3 Remove examples/local.mk.
4 examples/calc++/Makefile.am might be interesting to keep as is, since
5 it is an example in itself.
7 * examples/Makefile.am: Rename as...
8 * examples/local.mk: this.
10 * Makefile.am, configure.ac: Adjust.
12 2008-11-15 Akim Demaille <demaille@gostai.com>
14 Remove build-aux/Makefile.am.
15 Recursive Makefiles are really way too slow, let's get rid of some of
18 * build-aux/Makefile.am: Rename as...
19 * build-aux/local.mk: this.
21 * Makefile.am, configure.ac: Adjust.
23 2008-11-15 Akim Demaille <demaille@gostai.com>
25 Provide convenience constructors for locations and positions.
26 * data/location.cc (position::position): Accept file, line and
27 column as arguments with default values.
28 Always qualify initial line and column literals as unsigned.
29 (location::location): Provide convenience constructors.
31 2008-11-15 Akim Demaille <demaille@gostai.com>
33 Instead of using make_symbol<TOK_FOO>, generate make_FOO for each token type.
34 Using template buys us nothing, and makes it uselessly complex to
35 construct a symbol. Besides, it could not be generalized to other
36 languages, while make_FOO would work in C/Java etc.
38 * data/lalr1.cc (b4_symbol_): New.
40 (b4_symbol_constructor_declaration_)
41 (b4_symbol_constructor_definition_): Instead of generating
42 specializations of an overloaded template function, just generate
43 several functions whose names are forged from the token names
44 without the token.prefix.
45 (b4_symbol_constructor_declarations): Generate them for all the
46 symbols, not just by class of symbol type, now that instead of
47 specializing a function template by the token, we generate a
48 function named after the token.
49 (b4_symbol_constructor_specialization_)
50 (b4_symbol_constructor_specializations): Remove.
51 * etc/bench.pl.in: Adjust to this new API.
53 2008-11-13 Akim Demaille <demaille@gostai.com>
56 Provide a means to add a prefix to the name of the tokens as output in the
57 generated files. Because of name clashes, it is good to have such a
58 prefix such as TOK_ that protects from names such as EOF, FILE etc.
59 But it clutters the grammar itself.
61 * data/bison.m4 (token.prefix): Empty by default.
62 * data/c.m4 (b4_token_enum, b4_token_define): Use it.
63 * data/lalr1.cc (b4_symbol): Ditto.
65 2008-11-13 Akim Demaille <demaille@gostai.com>
67 Compute at M4 time some of the subtractions.
68 * data/lalr1.cc (b4_substract): New.
69 (b4_rhs_data): Use it.
71 2008-11-13 Akim Demaille <demaille@gostai.com>
74 This is allows the user to get the type of a token return by
77 * data/lalr1.cc (symbol::token): New.
78 (yytoknum_): Define when %define lex_symbol, independently of
80 (yytoken_number_): Move into...
81 (symbol::token): here, since that's the only use.
82 The other one is YYPRINT which was not officially supported
83 by lalr1.cc, and anyway it did not work since YYPRINT uses this
84 array under a different name (yytoknum).
86 2008-11-13 Akim Demaille <demaille@gostai.com>
89 * TODO (YYERRCODE): Mention the case of $undef.
91 2008-11-13 Akim Demaille <demaille@gostai.com>
94 * TODO (YYPRINT): New.
96 2008-11-13 Akim Demaille <demaille@gostai.com>
99 * data/lalr1.cc, data/yacc.c: Fix the description of the
100 yytranslate and yytoknum tables.
102 2008-11-13 Akim Demaille <demaille@gostai.com>
104 Define make_symbol in the header.
105 To reach good performances these functions should be inlined (yet this is
106 to measure precisely). To this end they must be available to the caller.
108 * data/lalr1.cc (b4_symbol_constructor_definition_): Qualify
109 location_type with the class name.
110 Since will now be output in the header, declare "inline".
111 No longer use b4_symbol_constructor_specializations, but
112 b4_symbol_constructor_definitions in the header.
113 Don't call it in the *.cc file.
115 2008-11-13 Akim Demaille <demaille@gostai.com>
117 Define yytranslate in the header for lex_symbol.
118 * data/lalr1.cc: Move the invocation of b4_yytranslate_definition
119 into the header file when using %define lex_symbol.
120 (yytranslate_): Declare inline.
122 2008-11-13 Akim Demaille <demaille@gostai.com>
124 Define the constructors of symbol_type in b4_symbol_constructor_definitions.
125 The constructors are called by the make_symbol functions, which a
126 forthcoming patch will move elsewhere. Hence the interest of putting them
129 The stack_symbol_type does not need to be moved, it is used only by the
132 * data/lalr1.cc: Move symbol_type and symbol_base_type
134 (b4_symbol_constructor_definitions): here.
137 2008-11-13 Akim Demaille <demaille@gostai.com>
139 Make it easier to move the definition of yytranslate_.
140 Forthcoming changes will make it possible to use yytranslate_
141 from outside the parser implementation file.
143 * data/lalr1.cc (b4_yytranslate_definition): New.
146 2008-11-13 Akim Demaille <demaille@gostai.com>
148 Remove useless class specification.
149 * data/lalr1.cc (b4_symbol_constructor_specialization_): No need
150 to refer to the class name to use a type defined by the class for
151 arguments of member functions.
153 2008-11-13 Akim Demaille <demaille@gostai.com>
155 Finer input type for yytranslate.
156 This patch is debatable: the tradition expects yylex to return an int
157 which happens to correspond to token_number (which is an enum). This
158 allows for instance to return characters (such as '*' etc.). But this
159 goes against the stronger typing I am trying to have with the new
160 lex interface which return a symbol_type. So in this case, feed
161 yytranslate_ with a token_type.
163 * data/lalr1.cc (yytranslate_): When in %define lex-symbol,
166 2008-11-13 Akim Demaille <demaille@gostai.com>
168 Honor lex-params in %define lex_symbol mode.
169 * data/lalr1.cc: Use b4_lex_param.
171 2008-11-13 Akim Demaille <demaille@gostai.com>
174 * src/output.c (symbol_definitions_output): Rename symbol
175 attributes type_name and has_type_name as type and has_type.
176 * data/lalr1.cc: Adjust uses.
178 2008-11-13 Akim Demaille <demaille@gostai.com>
180 Use b4_type_names for the union type.
181 The union used to compute the size of the variant used to iterate over the
182 type of all the symbols, with a lot of redundancy. Now iterate over the
183 lists of symbols having the same type-name.
185 * data/lalr1.cc (b4_char_sizeof_): New.
186 (b4_char_sizeof): Use it.
187 Adjust to be called with a list of numbers instead of a single
189 Adjust its caller for new-line issues.
191 2008-11-13 Akim Demaille <demaille@gostai.com>
193 Define the "identifier" of a symbol.
194 Symbols may have several string representations, for instance if they
195 have an alias. What I call its "id" is a string that can be used as
196 an identifier. May not exist.
198 Currently the symbols which have the "tag_is_id" flag set are those that
199 don't have an alias. Look harder for the id.
201 * src/output.c (is_identifier): Move to...
202 * src/symtab.c (is_identifier): here.
203 * src/symtab.h, src/symtab.c (symbol_id_get): New.
204 * src/output.c (symbol_definitions_output): Use it to define "id"
206 Remove the definition of "tag_is_id".
207 * data/lalr1.cc: Use the "id" and "has_id" whereever "tag" and
208 "tag_is_id" were used to produce code.
209 We still use "tag" for documentation.
211 2008-11-11 Akim Demaille <demaille@gostai.com>
213 Locations are no longer required by lalr1.cc.
214 * data/lalr1.cc (_b4_args, b4_args): New.
215 Adjust all uses of locations to make them optional.
216 * tests/c++.at (AT_CHECK_VARIANTS): No longer use the locations.
217 (AT_CHECK_NAMESPACE): Check the use of locations.
218 * tests/calc.at (_AT_DATA_CALC_Y): Adjust to be usable with or
219 without locations with lalr1.cc.
221 * tests/output.at: Check lalr1.cc with and without location
223 * tests/regression.at (_AT_DATA_EXPECT2_Y, _AT_DATA_DANCER_Y):
226 2008-11-11 Akim Demaille <demaille@gostai.com>
229 * tests/local.at (AT_FULL_COMPILE): New.
230 * tests/actions.at, tests/calc.at, tests/regression.at: Use it.
232 2008-11-11 Akim Demaille <demaille@gostai.com>
234 Support parens in calc++.
235 * doc/bison.texinfo (Calc++ Scanner, Calc++ Parser): Support parens.
236 * examples/calc++/test (run): Check the expected output.
240 2008-11-11 Akim Demaille <demaille@gostai.com>
242 Simplify lalr1.cc since %defines is mandatory.
243 * data/lalr1.cc: Remove useless calls to b4_defines_if.

248 * TODO (yysyntax_error): New item.
250 2008-11-11 Akim Demaille <demaille@gostai.com>

256 2008-11-11 Akim Demaille <demaille@gostai.com>
258 Support i18n of the parse error messages.
259 * TODO (lalr1.cc/I18n): Remove.
260 * data/lalr1.cc (yysyntax_error_): Support the translation of the
261 error messages, as done in yacc.c.
262 Stay within the yy* pseudo namespace.
264 2008-11-11 Akim Demaille <demaille@gostai.com>
267 * TODO (single stack, yysyntax_error): New.
269 2008-11-11 Akim Demaille <demaille@gostai.com>
271 Make it possible to return a symbol_type from yylex.
272 * data/lalr1.cc (b4_lex_symbol_if): New.
273 (parse): When lex_symbol is defined, expected yylex to return the

277 (bench_variant_parser): Exercise it.
279 2008-11-11 Akim Demaille <demaille@gostai.com>

287 Improve display of directives.

292 Use string_cast in the bench.

298 Replace yychar with a Boolean.
299 * data/lalr1.cc (parse::yychar): Replace by...
300 (parse::yyempty): this.
302 2008-11-11 Akim Demaille <demaille@gostai.com>
307 2008-11-11 Akim Demaille <demaille@gostai.com>
309 Let yytranslate handle the eof case.
310 * data/lalr1.cc (yytranslate_): Handle the EOF case.
312 No longer expect yychar to be equal to yyeof_, rather, test the
313 lookahead's (translated) kind.
315 2008-11-11 Akim Demaille <demaille@gostai.com>
317 yychar cannot be empty in yyerrlab.
318 * TODO (yychar == yyempty_): New.

320 This eases forthcoming changes related to yychar and yytranslate.

324 Bench: syntactic sugar for %define/#define.
325 * etc/bench.pl.in (parse_dirs): Support %d and #d with arguments.
326 (&bench_push_parser, bench_variant_parser): Use this feature.
330 2008-11-11 Akim Demaille <demaille@gostai.com>
332 Less memory pressure on the "list" bench.
333 * etc/bench.pl.in (generate_grammar_list): Do not accumulate all
334 the values, to limit memory pressure.
336 2008-11-11 Akim Demaille <demaille@gostai.com>
338 Introduce make_symbol.
339 make_symbol provides a means to construct a full symbol (kind, value,
340 location) in a single shot. It is meant to be a Symbol constructor,
341 parameterized by the symbol kind so that overloading would prevent
342 incorrect kind/value pairs. Unfortunately parameterized constructors do
343 not work well in C++ (unless the parameter also appears as an argument,
344 which is not acceptable), hence the use of a function instead of a

350 (b4_symbol_constructor_specializations)
351 (b4_symbol_constructor_definition_)
352 (b4_symbol_constructor_definitions): New.
353 Use them where appropriate to generate declaration, declaration of
354 the specializations, and implementations of the templated
355 overloaded function "make_symbol".
356 (variant::variant): Always define a default ctor.
357 Also provide a copy ctor.
358 (symbol_base_type, symbol_type): New ctor overloads for value-less
360 (symbol_type): Now public, so that functions such as yylex can use

365 Inform m4 whether a tag is a valid id.
366 * src/output.c (is_identifier): New.
367 (symbol_definitions_output): Use it to define tag_is_id.
368 But maybe this should be done at m4 level?
370 2008-11-11 Akim Demaille <demaille@gostai.com>
372 Test 214 was failing: it greps with a pattern containing [ ]*
373 which obviously meant to catch spaces and tabs, but contained only
374 spaces. Tabulations in sources are a nuisance, so to simplify the
375 matter, get rid of all the tabulations in the Java sources. The
376 other skeletons will be treated equally later.
378 * data/java.m4, data/lalr1.java: Untabify.
379 * tests/java.at: Simplify AT_CHECK_JAVA_GREP invocations:
380 tabulations are no longer generated.
382 2008-11-11 Paolo Bonzini <bonzini@gnu.org>
384 * bootstrap.conf: Replace m4/warning.m4 with warnings module.
385 * configure.ac: Adjust usage.
386 * lib/Makefile.am: Replace $(WARNING_CFLAGS) with $(WARN_CFLAGS).
387 * src/Makefile.am: Replace $(WARNING_CFLAGS) with $(WARN_CFLAGS).

392 Workaround Java's ``code too large'' problem for parser tables
393 in most cases, by using one function per initialization.

395 * data/lalr1.java (yypact_, yydefact_, yypgoto_, yydefgoto_,
396 yytable_, yycheck_, yystos_, yytoken_number_, yyr1_, yyr2_, yyrhs_
397 yyprhs_, yyrline_, yytranslate_table_): Use b4_integral_parser_table.

560 Change the handling of the symbols in the skeletons.
561 Before we were using tables which lines were the symbols and which
562 columns were things like number, tag, type-name etc. It is was
563 difficult to extend: each time a column was added, all the numbers had
564 to be updated (you asked for colon $2, not for "tag"). Also, it was
565 hard to filter these tables when only a subset of the symbols (say the
566 tokens, or the nterms, or the tokens that have and external number
567 *and* a type-name) was of interest.
569 Now instead of monolithic tables, we define one macro per cell. For
570 instance "b4_symbol(0, tag)" is a macro name which contents is
571 self-decriptive. The macro "b4_symbol" provides easier access to

620 Add %precedence support.
621 Unfortunately it is not possible to reuse the %prec directive. This
622 is because to please POSIX, we do not require to end the rules with a
623 semicolon. As a result,
627 is ambiguous: either a rule which precedence is that of baz, or a rule,
628 and then a declaration of the precedence of the token baz.

756 2008-11-09 Akim Demaille <demaille@gostai.com>
758 Rely on the state stack to display reduction traces.
759 To display rhs symbols before a reduction, we used information about the rule
760 reduced, which required the tables yyrhs and yyprhs. Now use rely only on the

889 Add "%define assert" to variants.
890 This is used to help the user catch cases where some value gets
891 ovewritten by a new one. This should not happen, as this will
894 Unfortunately this uncovered a bug in the C++ parser itself: the
895 lookahead value was not destroyed between two calls to yylex. For
896 instance if the previous lookahead was a std::string, and then an int,
897 then the value of the std::string was correctly taken (i.e., the
898 lookahead was now an empty string), but std::string structure itself
901 This is now done in variant::build(other&) (which is used to take the
902 value of the lookahead): other is not only stolen from its value, it
903 is also destroyed. This incurs a new performance penalty of a few
904 percent, and union becomes faster again.
906 * data/lalr1-fusion.cc (variant::build(other&)): Destroy other.

1178 2008-11-03 Akim Demaille <demaille@gostai.com>
1180 Add documentation to bench.pl.
1181 * etc/bench.pl.in: Comment changes.

1185 Fuse the three stacks into a single one.
1186 In order to make it easy to perform benchmarks to ensure that there are no
1187 performance loss, lalr1.cc is forked into lalr1-fusion.cc. Eventually,
1188 lalr1-fusion.cc will replace lalr1.cc.
1190 Meanwhile, to make sure that lalr1-fusion.cc is correctly exercized by the
1191 test suite, the user must install a symbolic link from lalr1.cc to it.
1193 Instead of having three stacks (state, value, location), use a stack
1194 of triples. This considerably simplifies the code (and it will be
1195 easier not to require locations as currently does the C++ parser),
1196 and also gives a 10% speedup according to etc/bench (probably mainly since
1197 memory allocation is done once instead of three times).
1199 Another motivation is to make it easier to destruct properly
1200 semantic values: now that they are bound to their state (hence
1201 symbol type) it will be easier to call the appropriate destructor.
1203 These changes should probably benefit the C parser too.
1205 * data/lalr1.cc: Copy as... * data/lalr1-fusion.cc: this new
1207 (b4_rhs_value, b4_rhs_location): New definitions overriding those
1209 (state_stack_type, semantic_stack_type, location_stack_type)
1210 (yystate_stack_, yysemantic_stack_, yylocation_stack_): Remove.
1211 (data_type, stack_type, yystack_): New.
1212 (YYLLOC_DEFAULT, yypush_): Adjust.
1213 (yyerror_range): Now based on data_type, not location_type.
1215 2008-11-03 Akim Demaille <demaille@gostai.com>
1217 Push the state, value, and location at the same time.
1218 This is needed to prepare a forthcoming patch that fuses the three
1221 * data/lalr1.cc (parser::yypush_): New.
1222 (parser::yynewstate): Change the semantics: instead of arriving to
1223 this label when value and location have been pushed, but yystate
1224 is to be pushed on the state stack, now the three of them must
1225 have been pushed before. yystate still must be the new state.
1226 This allows to use yypush_ everywhere instead of individual
1227 handling of the stacks.
1229 2008-11-03 Akim Demaille <demaille@gostai.com>
1231 Prefer references to pointers.
1232 * data/lalr1.cc (b4_symbol_actions): New, overrides the default C
1233 definition to use references instead of pointers.
1234 (yy_symbol_value_print_, yy_symbol_print_, yydestruct_):
1235 Take the value and location as references.
1238 2008-11-03 Akim Demaille <demaille@gostai.com>
1240 stack::size instead of stack::height.
1241 * data/lalr1.cc (stack::height): Rename as...
1242 (stack::size): this.
1243 Fix the output type.
1246 2008-11-03 Akim Demaille <demaille@gostai.com>
1248 Use variants to support objects as semantic values.
1249 This patch was inspired by work by Michiel De Wilde. But he used Boost
1250 variants which (i) requires Boost on the user side, (ii) is slow, and
1251 (iii) has useless overhead (the parser knows the type of the semantic value
1252 there is no reason to duplicate this information as Boost.Variants do).
1254 This implementation reserves a buffer large enough to store the largest
1255 objects. yy::variant implements this buffer. It was implemented with
1258 * src/output.c (type_names_output): New.
1259 (output_skeleton): Invoke it.
1260 * data/c++.m4 (b4_variant_if): New.
1261 (b4_symbol_value): If needed, provide a definition for variants.
1262 * data/lalr1.cc (b4_symbol_value, b4_symbol_action_)
1263 (b4_symbol_variant, _b4_char_sizeof_counter, _b4_char_sizeof_dummy)
1264 (b4_char_sizeof, yy::variant): New.
1265 (parser::parse): If variants are requested, define
1266 parser::union_type, parser::variant, change the definition of
1267 semantic_type, construct $$ before running the user action instead
1268 of performing a default $$ = $1.
1269 * examples/variant.yy: New.
1270 Based on an example by Michiel De Wilde.
1272 2008-11-03 Akim Demaille <demaille@gostai.com>
1274 Parameterize the extraction of semantic values.
1275 To make future changes easier, no longer rely on ".TYPE" being the
1276 way to get a semantic value.
1278 * data/c.m4 (b4_symbol_value): New.
1280 * data/c++.m4, data/yacc.c: Use it.
1281 * data/glr.c: Use b4_symbol_value.
1285 2008-11-03 Akim Demaille <demaille@gostai.com>

1308 2008-11-02 Joel E. Denny <jdenny@ces.clemson.edu>
1310 Say %language is experimental.
1311 We're thinking of extending it's effect on output file naming. See the

1389 Always put auxiliary code files in the same dir as other output files.
1390 * src/files.c (compute_file_name_parts): When the user specifies
1391 --output but not --file-prefix, extract the directory prefix from the
1392 file prefix not from the grammar file name. This affects the location
1393 of files like location.hh generated by the C++ skeleton. The includes

1656 (EXTRA_DIST): Remove GNUmakefile, handled by Gnulib. Add maint.mk,
1657 .prev-version, and .version.
1658 * NEWS (2.3b+): Rename to...
1659 (?.?): ... this because we're dropping the "+" version naming scheme,
1660 but, in general, we still can't be sure of our next release name.
1661 * bootstrap: Add a quick hack to remove from .gitignore the
1662 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile

1697 * bootstrap (insert_sorted_if_absent): Replace all uses with...
1698 (insert_vc_ignore): ... this new function, which prepends `/' to all
1699 .gitignore entries before passing them to insert_sorted_if_absent.
1700 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that
1701 .cvsignore files are maintained even though Bison developers run
1702 bootstrap while using Git.
1703 * .cvsignore (*.patch *.log log patches applied): Remove, apparently

1811 Update to the current gnulib CVS repository, and fix trigraph handling
1813 * bootstrap: Update gnulib CVS repository URL.
1814 (symlink_to_dir): Encapsulate the code that guarantees the destination
1815 directory exists into...
1816 (check_dst_dir): ... this new function, and...
1817 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
1818 fail when copying files into lib/uniwidth/.
1819 * src/output.c (prepare_symbols): When writing yytname muscles, where
1820 symbol names will be encoded in C-string literals, tell quotearg to
1821 escape trigraphs. This used to be the default in gnulib.
1822 * tests/regression.at (Token definitions): Because of the change in
1823 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
1824 escapes trigraphs in symbol names. Thus, yytname no longer has
1825 trigraphs unnecessarily doubly escaped. Update test case output.
1826 Extend test case to be sure Bison's own error messages will no longer
1827 have trigraphs in symbol names unnecessarily escaped once.

1844 arguments. Use brackets to indicate optional arguments.
1845 * src/getargs.c (usage): Explain the relationship between arguments of
1846 long and short options more completely. Document --defines and -d
1847 separately since the former takes an argument but, for POSIX Yacc, the
1849 (short_options): Let -W take an optional argument like --warnings.

2601 * data/push.c: ... to here and compute them from the value of the
2602 %define variable push_pull.
2603 * data/c-skel.m4: Instead of choosing the push.c skeleton for push
2604 parsing requests here...
2605 * data/yacc.c: ... hack this to switch to push.c any time
2606 b4_use_push_pull_flag or the %define variable push_pull is set. This
2607 will go away when we mv push.c yacc.c.
2608 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
2609 push parsing is not supported since unused %define variables are

2655 local variable `sep'.
2657 2007-09-21 Paul Eggert <eggert@cs.ucla.edu>
2659 * src/gram.c (rule_rhs_print_xml): Now static, since it isn't used
2661 * src/print-xml.c: Prefer "const" after types; that's more consistent.
2662 (xml_printf): Indent just 1 space for level.
2663 (e_char, xlate_char): Remove.
2664 (xml_escape_string): Rewrite to avoid undefined behavior (used
2665 storage that was freed from the stack).

2717 2006-08-18 Paul Eggert <eggert@cs.ucla.edu>
2718 Bruno Haible <bruno@clisp.org>
2720 * m4/bison-i18n.m4 (BISON_I18N): Also handle the case where yacc exists
2721 and is a script that invokes bison. Tighten the code. Add comments.
2723 2007-08-28 Joel E. Denny <jdenny@ces.clemson.edu>

2735 2007-08-17 Joel E. Denny <jdenny@ces.clemson.edu>
2737 In impure push mode, don't allow more than one yypstate to be allocated
2738 since multiple impure parsers would corrupt yynerrs.
2739 * data/push.c (yypstate_allocated): New static global variable
2741 (yypull_parse): If yypstate_new returns 0, don't report it as memory
2742 exhaustion if yypstate_allocated is 1, but still return 2.
2743 (yypstate_new): Invoke yyerror and return 0 if yypstate_allocated is
2744 already 1. Otherwise, set it to 1.
2745 (yypstate_delete): Set it to 0.
2746 * tests/push.at (Push Parsing: Multiple impure instances): New test

2820 Get rid of broken %no-parser, -n, and --no-parser implementation and
2822 * TODO: Don't mention them.
2823 * doc/bison.1: Likewise.
2824 * doc/bison.texinfo (Decl Summary): Likewise.
2825 (Bison Options): Likewise.
2826 (Option Cross Key): Likewise.
2827 * src/getargs.c (no_parser_flag): Remove global variable.
2828 (usage): Don't print description of -n and --no-parser.
2829 (long_options): Remove --no-parser entry here.
2830 (getargs): Remove -n case in the switch here.
2831 * src/getargs.h (no_parser_flag): Remove extern.
2832 * tests/regression.at (Web2c Actions): Remove comment that mentions
2835 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
2837 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
2838 name user variables starting with `yy'. Just pass NULL instead of a
2839 dummy local &yylval to yypush_parse.
2840 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
2843 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
2845 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
2846 true since it's then always used regardless of whether yyoverflow is
2847 defined. Reported by Christian Burger at
2848 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
2849 * THANKS: Add Christian Burger.
2851 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
2852 node names: say "Decl Summary" not "Bison Declaration Summary".
2854 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
2856 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
2857 determine whether this function has already complained about an invalid
2858 value for a %define boolean variable, don't check whether Bison has
2859 ever examined the value. As written, the check was a tautology.
2860 Instead, record and check for this complaint using a separate muscle.
2862 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
2864 Fix push parsing memory leak reported by Brandon Lucia at
2865 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
2866 * THANKS: Add Brandon Lucia.
2867 * data/push.c (yypstate_delete): Free the stack if it was reallocated
2868 but the parse never completed and thus freed it.
2869 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
2870 * tests/testsuite.at: Include push.at.
2871 * test/push.at: New.
2872 (Push Parsing: Memory Leak for Early Deletion): New test case.
2874 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
2876 Improve handling of multiple S/R conflicts in the same state and of S/R
2877 conflicts involving multiple reductions.
2878 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
2879 set for a state here or Bison will abort if it is reassigned on a
2880 later conflicted reduction in the same state.
2881 Similarly, don't finalize and assign the solved conflicts report here
2882 or it will be lost if it is reassigned on a later conflicted reduction
2884 (set_conflicts): Instead, assign them both here after all S/R conflicts
2885 in the state have been fully examined.
2886 * src/print.c (shift_set): Rename to...
2887 (no_reduce_set): ... this.
2888 (print_reductions): Update for rename, and add %nonassoc error action
2889 tokens to no_reduce_set so that, when printing the first remaining
2890 reduction on an error action token, the reduction is enclosed in
2892 (print_results): Update for rename.
2893 * tests/conflicts.at (Solved conflicts report for multiple reductions
2894 in a state): New test case.
2895 (%nonassoc error actions for multiple reductions in a state): New test
2898 * src/main.c (main): Don't depend on C99 features.
2900 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
2902 * build-aux/.cvsignore: Add compile.
2903 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
2906 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
2908 * bootstrap (slurp): Create target directories that don't exist.
2909 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
2911 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
2913 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
2915 * closure.c (closure): Likewise.
2916 * state.h (reductions): Comment sorting of rules.
2917 (state): Comment sorting of items.
2919 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
2921 Fix C++ test cases after recent Gnulib changes. Discussed starting at
2922 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
2923 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
2924 definition in order to avoid Gnulib headers since we don't use config.h
2926 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
2927 rather than AT_DATA so that config.h is included.
2929 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
2931 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
2932 instead of fprintf. Guard these functions with #if YYDEBUG instead of
2933 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
2934 and so that YYFPRINTF is guaranteed to be defined here.
2936 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
2938 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
2940 (muscle_percent_define_check_values): ... this more helpful function.
2941 Again, it's not used yet, but it will be.
2942 * src/muscle_tab.h: Likewise.
2944 Improve some comments in parser table construction.
2945 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
2946 (generate_states): Don't mention ruleset, which is internal to closure.
2947 * src/closure.c (closure): Explain sorting of core and itemset, which
2948 is required for this function to behave correctly.
2949 * src/closure.h (closure): Mention sorting.
2951 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
2953 * src/lalr.c (state_lookahead_tokens_count): For code readability,
2954 move the check for disabled transitions to an aver since conflict
2955 resolution hasn't happened yet.
2957 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
2958 labels a state as inconsistent just because it has error transitions.
2959 The original form of this check appeared in revision 1.1 of lalr.c,
2960 which was committed on 1991-12-21. Now (at least), changing the
2961 consistency label on such a state appears to have no useful effect in
2962 any of the places it is examined, which I enumerate below. The key
2963 point to understanding each item in this enumeration is that a state
2964 with an error transition is labelled consistent in the first place only
2965 if it has no rules, so the check cannot matter for states that have
2966 rules. (1) Labelling a state as inconsistent will cause set_conflicts
2967 to try to identify its conflicts, and a state must have *rules* to have
2968 conflicts. (2) Labelling a state as inconsistent will affect how
2969 action_row sets the default *rule* for the state. (3) Labelling a
2970 state as inconsistent will cause build_relations to add lookback edges
2971 to *rules* in that state.
2972 * src/state.h (struct state): Word the comment for member consistent
2975 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
2977 Don't depend on C99 features.
2978 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
2979 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
2980 * src/reader.c (check_and_convert_grammar): Fix for-loop.
2981 * src/state.c (state_mark_reachable_states): Fix for-loop.
2982 (state_remove_unreachable_states): Fix for-loop.
2984 Don't widen struct state with member reachable just to temporarily
2985 record reachability. Instead, use a local bitset.
2986 * src/state.h (struct state): Remove member.
2987 * src/state.c (state_new): Don't initialize it.
2988 (state_mark_reachable_states): Rename to...
2989 (state_record_reachable_states): ... this, and use bitset.
2990 (state_remove_unreachable_states): Use bitset.
2992 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
2994 * src/Makefile.am (yacc): Quote target action commands properly so
2995 that the yacc script isn't corrupt. Reported by Hans Aberg at
2996 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
2998 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
2999 the case of pure parsers. Reported by Frans Englich at
3000 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
3001 * THANKS: Add Frans Englich.
3003 * NEWS (2.3a+): In the %code entry, reference section `Bison
3004 Declaration Summary' from the manual now since the %code summary has
3006 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
3007 in the rules section must be terminated by semicolons.
3009 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
3011 Extend the front-end API for %define variables to more completely
3012 mirror the back-end. This will be useful in the future.
3013 * data/bison.m4 (b4_percent_define_get, b4_percent_define_ifdef):
3014 Update comments to mention the new front-end counterparts of these
3016 * src/muscle_tab.c (MUSCLE_COMMON_DECODE): New macro with common code
3017 for muscle_string_decode and muscle_location_decode.

3228 Undo my 2007-02-07 change, switching back to the c-strcase module
3229 introduced in the 2007-02-03 change. Bruno Haible reported that
3230 the 2007-02-07 change would be dangerous in Turkish if we add a
3231 language whose name contains "i", since "i" is not lowercase "I"
3233 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
3234 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
3235 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
3236 * m4/.cvsignore: Remove strcase.m4.
3237 * src/getargs.c: Revert 2007-02-07 change, as follows.
3238 Include c-strcase.h.
3239 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
3241 2007-02-11 Bruno Haible <bruno@clisp.org>
3243 Enable the Java related testsuite tests when the only Java compiler
3244 found is a gcj < 4.3. Discussed at
3245 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
3246 * configure.ac (gt_JAVACOMP): Don't specify a target_version.

3254 * src/reader.c (packgram): Move translation of rule actions from the
3255 beginning of packgram to...
3256 (check_and_convert_grammar): ... here right before packgram is invoked
3257 so it's easier to write more complete comments, and remove redundant
3260 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
3262 As in semantic actions, make @$ in %initial-action, %destructor, and
3263 %printer imply %locations.
3264 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
3266 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...

3274 now that gnulib strcase has been fixed.
3275 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
3276 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
3277 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
3278 * m4/.cvsignore: Add strcase.m4.
3279 * src/getargs.c: Revert 2007-02-03 change, as follows.
3280 Don't include c-strcase.h.
3281 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
3282 strcasecmp has "unspecified behavior" outside the POSIX locale,
3283 but it works fine in practice if at least one argument is ASCII,
3284 as is the case in Bison.
3286 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
3288 * tests/java.at: Skip tests if only one of javac/java is present.
3289 Reported by Joel E. Denny.
3290 * tests/atlocal.in: Adjust copyright years.

3294 * data/lalr1.java (Stack): Work around old verifiers that disallow
3295 access to the private fields of an inner class, from the outer class.
3296 We can make Stack's fields public because user code doesn't have access
3297 to the instance of Stack used by parse(). Reported by Paul Eggert.
3299 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
3301 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
3302 the right spot for these files?
3303 * bootstrap.conf (gnulib_modules): Add c-strcase.
3304 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
3306 * src/getargs.c: Include c-strcase.h.
3307 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
3308 to avoid unspecified behavior.
3310 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>

3318 * data/c++.m4: Adjust default definitions of %define variables.
3319 * data/java.m4: Adjust default definitions of %define variables.
3320 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according

3351 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
3352 at_directive_argv arguments so these no longer have to be global
3353 variables. Also, update the implementation for the following changes.
3354 (fail_for_at_directive_too_many_args,
3355 fail_for_at_directive_too_few_args): Add at_directive_name argument.
3356 (at_directive_name): Remove as at_directive_argv[0] will be used for
3358 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
3359 for the directive name.

3362 (INITIAL): Update directive start action for above changes.
3363 (SC_AT_DIRECTIVE_ARG): Rename to...
3364 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
3365 (SC_AT_DIRECTIVE_SKIP_WS): Update.
3366 (scan_skel): Move yylex_destroy to...
3367 (skel_scanner_free): ... here.
3368 * tests/skeletons.at (installed skeleton file name): Rename to...
3369 (installed skeleton file names): ... this.
3371 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
3373 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
3374 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
3375 Summary" not "Directives".
3376 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
3377 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
3378 since the former is now the more complete one.
3379 (Prologue Alternatives): Likewise and do the same for %defines.
3380 (Table of Symbols): Add summary of %code, add summary of %define, and
3381 move full %code documentation to...
3382 (Decl Summary): ... here for consistency with other entries in these
3384 Move %define entry in order to keep this list alphabetized.
3385 Reword %define entry a little to put less emphasis on the skeleton
3386 concept, which most users shouldn't have to think about.
3388 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
3390 Adjust to recent gnulib changes.
3391 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.

3399 Simplify implementation of unqualified %code, implement macros for
3400 uniform treatment of boolean %define flags. Document %define.

3472 Clean up %define and %code implementation in M4 some. Most
3473 importantly, rename all related macros to be in the b4_percent_define
3474 and b4_percent_code namespaces. Also, complete support for `.' in
3475 %define variable names and %code qualifiers.
3476 * data/bison.m4 (b4_check_user_names): Check for special
3477 "SKELETON-NAMESPACE(name)" macros instead of using two nested
3479 (b4_get_percent_define, b4_get_percent_code): Rename to...
3480 (b4_percent_define_get, b4_percent_code_get): ... these.
3481 Extend documentation with examples.
3482 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
3483 b4_percent_define_skeleton_variables and
3484 b4_percent_code_skeleton_qualifiers.
3485 Expect any value for the %define variable `foo' to be stored in the
3486 macro named `b4_percent_define(foo)'; expect any %code blocks for the
3487 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
3488 expect any unqualified %code blocks to be stored in a macro named
3489 `b4_percent_code_unqualified'.
3490 Use m4_indir so that %define variable names and %code qualifiers can
3491 contain `.', which is allowed by the grammar parser.
3492 (b4_percent_define_default): New macro to set a default value for a
3494 (m4_wrap): Update wrapped code, and fix some underquoting.
3495 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
3496 Expect grammar uses of %define variables and %code qualifiers to be
3497 defined in b4_percent_define_user_variables and
3498 b4_percent_code_user_qualifiers.
3499 * data/c++.m4: Use b4_percent_define_default rather than
3500 m4_define_default. Fix some underquoting. Skeleton usage of %define
3501 variable define_location_comparison now implies skeleton usage of
3502 %define variable filename_type.
3503 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
3504 data/push.c, data/yacc.c: Update macro names.
3505 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
3508 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
3510 DJGPP specific issues.
3512 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
3513 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
3515 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
3517 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
3518 run parsers in all tests so that Valgrind is invoked during
3519 maintainer-check-valgrind.
3520 (Duplicate representation of merged trees): Free all semantic values.
3521 (Duplicated user destructor for lookahead): Likewise.
3523 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
3525 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
3526 command-line prefix.
3527 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
3528 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
3529 miss Valgrind messages.
3530 (Exploding the Stack Size with Malloc): Likewise.
3532 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
3534 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
3535 locals. Reported by Juan Manuel Guerrero at
3536 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
3537 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
3538 Fix some indentation also.
3539 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
3540 explaining this issue.
3542 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
3543 and Joel E. Denny <jdenny@ces.clemson.edu>
3545 Simplify union and prologue handling, and escape union and lex/parse
3546 params with digraphs.
3547 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
3548 values to the empty string since these are no longer guaranteed
3549 initialized by the front-end.
3550 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
3551 braces around b4_user_stype since this is no longer done by the
3553 * src/files.c, src/files.h (pre_prologue_obstack,
3554 post_prologue_obstack): Remove.
3555 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
3556 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
3557 with digraphs. This fixes lex params and parse params.
3558 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
3559 * src/output.c (prepare): Remove muscle insertion of the prologues.
3560 (output): Remove freeing of pre_prologue_obstack and
3561 post_prologue_obstack.
3562 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
3563 than prologue_augment for prologue parsing so you don't need prologue
3565 (grammar_declaration): For %union RHS, use `braceless' instead of
3566 "{...}" so that braces are already stripped and code is escaped with
3568 * src/reader.c (prologue_augment): Remove.
3569 (reader): Remove initialization of pre_prologue_obstack and
3570 post_prologue_obstack.
3571 * src/reader.h (prologue_augment): Remove.
3573 * data/c.m4: Remove stray parenthesis.
3575 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
3577 Remove quotes from variables names in %define directives and from
3578 qualifiers in %code directives, and restrict the characters that are
3579 allowed in them to M4-friendly ones. For %define, continue to support
3580 the quoted form as a deprecated feature. Discussed starting at
3581 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
3582 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
3584 * doc/bison.texinfo (Prologue Alternatives): Update.
3585 (Decl Summary): In %defines entry, update mention of `%code requires'
3586 and `%code provides'.
3587 (C++ Location Values): Update %define uses.
3588 (Calc++ Parser Interface): Likewise.
3589 (Calc++ Parser): Likewise, and update `%code requires' uses.
3590 (Table of Symbols): Update %code documentation.
3591 * src/parse-gram.y (prologue_declaration): For %define variables, use
3592 `variable' instead of `STRING'.
3593 (grammar_declaration): For %code qualifiers, use `ID' instead of
3595 (variable): New nonterminal that takes an `ID' or a `STRING'.
3596 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
3598 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
3599 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
3600 (%define errors): Update %define uses.
3602 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
3604 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
3605 instead of muscle_insert for %define values so that M4-special
3606 characters are replaced with digraphs.
3607 * tests/input.at (%define errors): Extend to check weird values.
3609 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
3611 Instead of having skeletons declare all valid %define variables and
3612 %code qualifiers, provide macros that retrieve the associated values
3613 and build these lists automatically. Thus Bison will now warn when a
3614 variable or qualifier is not used by the skeleton in the current
3615 invocation regardless of whether it might sometimes be used by that
3616 skeleton in other invocations. Also, move all %define value macros to
3617 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
3618 form, which is replaced by %code.
3619 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
3620 (b4_check_user_names): ... this, and change the series of valid name
3621 arguments to a single list argument for names used in the skeleton
3622 similar to the existing list argument for names used in the grammar.
3623 Warn instead of complaining.
3624 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
3625 values and %code code, to format %code code properly, and to build
3626 lists of all %define variables and %code qualifiers used in the
3627 skeleton: b4_skeleton_percent_define_variables and
3628 b4_skeleton_percent_code_qualifiers.
3629 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
3631 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
3632 the skeleton names lists can finish building first. In place of
3633 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
3634 expect the lists b4_user_percent_define_variables and
3635 b4_user_percent_code_qualifiers.
3636 * data/c++.m4: Where setting default values for b4_parser_class_name,
3637 b4_location_type, b4_filename_type, b4_namespace, and
3638 b4_define_location_comparison, update their names to the
3639 b4_percent_define_ namespace.
3640 * data/glr.c: Don't use b4_check_percent_define_variables and
3641 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
3642 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
3643 (b4_parser_class_name, b4_namespace): Define these using
3644 b4_get_percent_define for parser_class_name and namespace.
3645 * data/location.cc: Use b4_get_percent_define.
3646 * data/push.c: Don't use b4_check_percent_define_variables and
3647 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
3648 * data/yacc.c: Likewise, and don't call m4_exit in
3649 b4_use_push_for_pull_if or m4_wrap code will never execute.
3650 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
3652 (muscle_grow_user_name_list): ... this for consistency with the
3653 terminology used in bison.m4.
3654 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
3655 %define variable names, and rename muscle used_percent_define_variables
3656 to user_percent_define_variables.
3657 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
3658 user_percent_code_qualifiers.
3660 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
3661 {CODE} form is no longer accepted.
3662 * tests/input.at (Reject bad %code qualifiers): Rename to...
3663 (Reject unused %code qualifiers): ... this, and update test output.
3664 (%define error): Update test output.
3666 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
3668 Check for unrecognized %define variables similar to checking for
3669 unrecognized %code qualifiers. Check for redefined %define variables.
3670 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
3672 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
3673 (b4_check_percent_define_variables): New, also wraps it.
3674 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
3675 variables using b4_check_percent_define_variables.
3676 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
3677 all those exercised in the test suite and all those listed in the
3678 `Default values' section of c++.m4. Are there others?
3679 * data/push.c, data/yacc.c: Declare no valid %define variables.
3680 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
3681 similar to muscle_find, but it works even when the muscle stores a
3683 (muscle_grow_used_name_list): New function for constructing the used
3684 name list muscles that b4_check_for_unrecognized_names requires.
3685 * src/parse-gram.y (prologue_declaration): Warn if a variable is
3686 %define'd more than once. Define the b4_used_percent_define_variables
3687 muscle with muscle_grow_used_name_list.
3688 (grammar_declaration): Abbreviate %code code with
3689 muscle_grow_used_name_list.
3690 * tests/input.at (%define errors): New.
3692 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
3694 Provide warn_at, complain_at, and fatal_at function callbacks to the
3695 skeletons, and use this for %code qualifier complaints.
3696 * data/bison.m4 (b4_error_at): New, invoked by...
3697 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
3698 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
3699 @fatal_at(...@) directives.
3700 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
3701 qualifiers in b4_used_percent_code_qualifiers and to use
3703 * src/location.c, src/location.h (boundary_set_from_string): New global
3705 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
3707 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
3708 to b4_used_percent_code_qualifiers.
3709 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
3711 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
3712 (lineno): Rename to...
3713 (out_lineno): ... this so I don't misunderstand it again.
3714 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
3715 here; these newlines are in the input but not the output file.
3716 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
3717 (at_directive_perform): ... this new static function, and add handling
3718 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
3720 * tests/input.at (Reject bad %code qualifiers): Update test output with
3721 locations and extend.
3723 * tests/output.at (Output file name: [, Output file name: ]): Remove
3724 bogus comment about these tests failing.
3726 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
3728 Clean up b4_check_percent_code_qualifiers a little.
3729 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
3730 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
3731 documentation and add examples.
3732 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
3735 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
3737 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
3738 unreliable -- especially when they're hidden inside another macro.
3739 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
3740 data/c.m4: Remove m4_divert(-1).
3741 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
3742 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
3743 m4_divert_push(0) and m4_divert_pop(0).
3744 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
3745 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
3746 pushed and popped by m4sugar, should be first on the stack.
3748 Provide warn, complain, and fatal function callbacks to the skeletons.
3749 This provides more flexibility than m4_fatal, improves the error
3750 message format, and captures messages for translation. Discussed
3752 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
3753 * data/bison.m4 (b4_error): New, invoked by...
3754 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
3755 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
3756 directives. Because these M4 macros might be called when the current
3757 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
3758 the previous removal of uses of m4_divert, which caused trouble.
3759 (b4_check_percent_code_qualifiers): Use b4_complain instead of
3760 m4_fatal to report unrecognized %code qualifiers.
3761 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
3762 push parser requests.
3763 * data/glr.c: Use b4_complain instead of m4_fatal to report
3764 non-deterministic push parser requests.
3765 Update @output usage to @output(...@) form.
3766 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
3767 report missing %defines. Update @output usage to @output(...@) form.
3768 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
3770 * src/main.c (main): Invoke skel_scanner_free.
3771 * src/scan-skel.h (skel_scanner_free): Prototype new function.
3772 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
3773 obstack_for_string from flex-scanner.h.
3774 (YY_DECL): Use to declare skel_lex static.
3775 (decode_at_digraphs): Remove; now handled in the new
3776 SC_AT_DIRECTIVE_ARG start condition.
3777 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
3779 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
3780 at_directive_argv): New static globals.
3781 (INITIAL): Use fail_for_invalid_at.
3782 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
3783 recognize the start of a generalized `@directive(...@)' form and
3785 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
3786 directive args (using the new obstack_for_string), to decode the
3787 contained @ diagraphs, and to perform the directive. It recognizes
3788 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
3790 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
3791 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
3793 (scan_skel): Initialize obstack_for_string on the first call.
3794 (skel_scanner_free): New function to free obstack_for_string.
3795 * tests/input.at (Reject bad %code qualifiers): Update test output.
3797 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
3799 Consolidate the 4 prologue alternative directives (%code, %requires,
3800 %provides, and %code-top) into a single %code directive with an
3801 optional qualifier field. Discussed at
3802 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
3803 * NEWS (2.3a+): Rewrite the existing entry for the prologue
3805 * doc/bison.texinfo (Prologue Alternatives): Update.
3806 (Decl Summary): Update to %code "requires" and %code "provides".
3807 (Calc++ Parser): Update to %code "requires".
3808 (Table of Symbols): Remove entries for %requires, %provides, and
3809 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
3810 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
3811 are replaced by b4_percent_code_provides and b4_percent_code_requires,
3812 which are skeleton-specific.
3813 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
3814 declare what %code qualifiers it supports and to complain if any other
3815 qualifiers were used in the grammar.
3816 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
3817 and b4_user_code([b4_percent_code_provides]) in place of
3818 b4_user_requires and b4_user_provides.
3819 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
3820 Add b4_user_code([b4_percent_code_top]) and
3821 b4_user_code([b4_percent_code]).
3822 Invoke b4_check_percent_code_qualifiers.
3823 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
3824 PERCENT_REQUIRES): Remove.
3825 (grammar_declaration): Remove RHS's for %code-top, %provides, and
3826 %requires. Rewrite the %code RHS as the unqualified form defining the
3827 muscle b4_percent_code. Add another RHS for the qualified %code form,
3828 which defines muscles of the form b4_percent_code_QUALIFIER and the
3829 b4_used_percent_code_qualifiers muscle.
3830 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
3831 PERCENT_REQUIRES): Remove.
3832 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
3833 %code "requires" and %code "provides".
3834 * tests/input.at (Reject bad %code qualifiers): New.
3836 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
3838 Use the new code_props interface for destructors and printers.
3839 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
3840 printer_location members, and change the type of the destructor and
3841 printer members to code_props.
3842 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
3843 symbol_printer_get, semantic_type_destructor_set,
3844 semantic_type_printer_set, default_tagged_destructor_set,
3845 default_tagless_destructor_set, default_tagged_printer_set,
3846 default_tagless_printer_set): Use code_props in arguments and return
3847 types in place of char const * and location.
3848 (symbol_destructor_location_get, symbol_printer_location_get): Remove
3849 since the locations are now contained in the return of
3850 symbol_destructor_get and symbol_printer_get.
3851 * src/output.c (symbol_destructors_output, symbol_printers_output):
3853 (symbol_code_props_output): ... this to eliminate duplicate code.
3854 (output_skeleton): Update to use symbol_code_props_output.
3855 * src/reader.c (symbol_should_be_used): Update use of
3856 symbol_destructor_get.
3857 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
3858 Update uses of the various _destructor_set and _printer_set functions.
3859 * src/symtab.c: (default_tagged_destructor_location,
3860 default_tagless_destructor_location, default_tagged_printer_location,
3861 default_tagless_printer_location): Remove since we...
3862 (default_tagged_destructor, default_tagless_destructor,
3863 default_tagged_printer, default_tagless_printer): ... change the type
3864 of these to code_props.
3865 (symbol_new, semantic_type_new, symbol_destructor_set,
3866 semantic_type_destructor_set, symbol_destructor_get,
3867 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
3868 symbol_check_alias_consistency, default_tagged_destructor_set,
3869 default_tagless_destructor_set, default_tagged_printer_set,
3870 default_tagless_printer_set): Update.
3871 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
3872 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
3874 (symbol_print): Use SYMBOL_CODE_PRINT.
3876 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
3878 Use the new code_props interface for rule actions.
3879 * src/symlist.h (symbol_list): Replace action, action_location, and
3880 used members with a code_props action_props member.
3881 * src/reader.c (symbol_should_be_used, grammar_rule_check,
3882 grammar_midrule_action, grammar_current_rule_merge_set,
3883 grammar_current_rule_symbol_append, packgram): Update.
3884 * src/scan-code.h (translate_rule_action): Remove, no longer used.
3885 * src/scan-code.l (handle_action_dollar): Update.
3886 (translate_rule_action): Remove, no longer used.
3887 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
3889 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
3891 Use the new code_props interface in parse-gram.y.
3892 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
3893 Update all uses of translate_* functions to use the new code_props
3894 interface and to use gram_scanner_last_string_free and
3895 code_scanner_last_string_free where possible.
3896 (grammar_declaration): symbol_list_destructor_set and
3897 symbol_list_printer_set now perform the translation, so don't do it
3898 here. Use gram_scanner_last_string_free where possible.
3899 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
3900 translate_code): Remove, no longer used.
3901 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
3902 symbol_list_printer_set): Perform code translation here rather than
3903 depending on the caller to do so.
3905 * src/symlist.h (struct symbol_list): Correct some documentation typos.
3906 * src/scan-gram.h (gram_last_string): Remove declaration.
3907 * src/scan-gram.l (last_string): Declare it static.
3909 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
3911 Encapsulate code properties and related functionality for the various
3912 destructors, printers, and actions into a code_props structure and
3913 interface. This patch merely implements code_props in scan-code.h and
3914 scan-code.l. Future patches will rewrite other modules to use it.
3915 Discussed starting at
3916 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
3917 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
3918 consistently initialize const structs that have an empty location
3920 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
3921 to ensure consistency.
3922 * src/scan-code.h (code_props): New structure.
3923 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
3924 function, macro, and const global variable for initializing a
3925 code_props with no code.
3926 (code_props_plain_init, code_props_symbol_action_init,
3927 code_props_rule_action_init, code_props_translate_code): The rest of
3928 the new code_props functional interface. Among other things, the init
3929 functions set the code_props kind field so that
3930 code_props_translate_code will know whether to behave like
3931 translate_symbol_action, translate_rule_action, or translate_code.
3932 These old translate functions must remain until all other modules are
3933 updated to use the new code_props interface.
3934 (code_scanner_last_string_free): New function similar to
3935 gram_scanner_last_string_free.
3936 (code_scanner_free): Add documentation.
3937 * src/scan-code.l: Implement the new interface.
3938 (code_lex): Make it static, add a code_props* argument, and remove the
3940 (last_string): New static global similar to the one in scan-gram.l.
3941 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
3943 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
3944 code_props since Bison may one day use this information for destructors
3946 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
3947 (handle_action_dollar): Use symbol_list_n_get and set used flag
3948 directly since symbol_list_n_used_set is removed.
3949 (translate_action): Add a code_props* argument and remove the rule,
3950 action, and location arguments. Pass the code_props* on to code_lex.
3951 (translate_rule_action, translate_symbol_action, translate_code):
3952 Rewrite as wrappers around the new code_props interface.
3953 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
3954 it would eventually need to break the encapsulation of code_props.
3956 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
3958 * etc/.cvsignore: New.
3960 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
3962 Add maintainer-push-check to run maintainer-check using push parsing in
3963 place of pull parsing where available.
3964 * Makefile.am (maintainer-push-check): New.
3965 * data/bison.m4 (b4_use_push_for_pull_if): New.
3966 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
3967 appropriately based on their existing values.
3968 (yypush_parse): Don't print push-parser-specific diagnostics if push
3969 parsing is being used in place of pull parsing.
3970 * data/yacc.c: If push parsing should replace pull parsing, redirect to
3972 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
3973 variable, and insert b4_use_push_for_pull_flag into muscles.
3974 * tests/Makefile.am (maintainer-push-check): New.
3976 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
3978 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
3979 (whether successful or failed) so that yypush_parse can be invoked
3980 again to start a new parse using the same yypstate.
3981 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
3982 check multiple yypull_parse invocations on the same yypstate. For pull
3983 mode, extend to check multiple yyparse invocations.
3984 (Exploding the Stack Size with Alloca): Extend to try with
3986 (Exploding the Stack Size with Malloc): Likewise.
3988 * tests/calc.at (Simple LALR Calculator): Don't specify
3989 %skeleton "push.c" since %push-pull-parser implies that now.
3990 * tests/headers.at (export YYLTYPE): Don't check for the push
3991 declarations. Otherwise, this test case can't be used to see if push
3992 mode can truly emulate pull mode.
3993 * tests/input.at (Torturing the Scanner): Likewise.
3994 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
3995 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
3996 AT_YACC_IF, which now includes the case of push mode since %skeleton
3997 need not be used for push mode. This will be more intuitive once
3998 push.c is renamed to yacc.c.
4000 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
4002 For push mode, convert yyparse from a macro to a function, invoke yylex
4003 instead of passing a yylexp argument to yypull_parse, and don't
4004 generate yypull_parse or yyparse unless %push-pull-parser is declared.
4005 Discussed starting at
4006 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
4007 * data/bison.m4 (b4_pull_if): New.
4008 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
4009 * data/push.c: Improve M4 quoting a little.
4010 (b4_generate_macro_args, b4_parenthesize): Remove.
4011 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
4012 any time a pull parser is requested.
4013 Don't #define this as a wrapper around yypull_parse. Instead, when
4014 both push and pull are requested, make it a function that does that
4016 (yypull_parse): If there's a b4_prefix, #define this to
4017 b4_prefix[pull_parse] when both push and pull are requested.
4018 Don't define this as a function unless both push and pull are
4020 Remove the yylexp argument and hard-code yylex invocation instead.
4021 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
4023 * src/getargs.c (pull_parser): New global initialized to true.
4024 * getargs.h (pull_parser): extern it.
4025 * src/output.c (prepare): Insert pull_flag muscle.
4026 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
4027 (prologue_declaration): Set both push_parser and pull_parser = true for
4028 %push-pull-parser. Set push_parser = true and pull_parser = false for
4030 * src/scan-gram.l: Don't accept %push_parser as an alternative to
4031 %push-parser since there's no backward-compatibility concern here.
4032 Scan %push-pull-parser.
4033 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
4034 instead of %push-parser.
4035 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
4036 prototype it in the module that calls yyparse.
4037 * tests/input.at (Torturing the Scanner): Likewise.
4038 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
4040 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
4042 Update etc/bench.pl. Optimize push mode a little (the yyn change
4043 deserves most of the credit).
4044 * Makefile.am (SUBDIRS): Add etc subdirectory.
4045 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
4046 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
4047 yytoken, yyval, and yyloc declarations to...
4048 (yyparse or yypush_parse): ... here to improve performance. For
4049 yypush_parse invocations after the first, be sure to assign yyn its old
4051 (yypstate_new): Don't bother initializing the yyresult field since the
4052 initial value isn't used.
4053 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
4054 remove the #define that, in push mode, set it to yyps->NAME.
4055 * etc/Makefile.am: New.
4056 * etc/bench.pl: Remove and build it instead from...
4057 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
4058 "tests/bison" from the build directory by default rather than just
4059 invoking "bison" from $PATH.
4060 (calc_grammar): Update push parser code: don't declare yylval globally,
4061 don't define yyparse_wrapper, and don't #define yyparse.
4062 (bench_grammar): Update to check all working combinations of yacc.c,
4063 push.c, impure, pure, pull, and push.
4065 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
4067 For push mode, add pull wrappers around yypush_parse.
4068 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
4069 (yypull_parse): New function wrapping yypush_parse.
4070 (yyparse): New #define wrapping yypull_parse.
4071 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
4073 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
4074 prototype yylex in the module that calls yyparse, and don't prototype
4075 yyparse there. Otherwise, the yyparse expansion won't compile.
4076 * tests/input.at (Torturing the Scanner): Likewise.
4078 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
4080 Enable push parsers to operate in impure mode. Thus, %push-parser no
4081 longer implies %pure-parser. The point of this change is to move
4082 towards being able to test the push parser code by running the entire
4083 test suite as if %push-parser had been declared.
4084 * data/push.c (yypush_parse): For impure mode, remove the
4085 yypushed_char, yypushed_val, and yypushed_loc arguments.
4086 Instead, declare these as local variables initialized to the global
4087 yychar, yylval, and yylloc.
4088 For the first yypush_parse invocation only, restore the initial values
4089 of these global variables when it's time to read a token since they
4090 have been overwritten.
4091 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
4093 * tests/calc.at (Simple LALR(1) Calculator): Always declare
4094 %pure-parser along with %push-parser since this test case was designed
4095 for pure push parsers.
4096 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
4097 (AT_YACC_OR_PUSH_IF): New.
4098 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
4099 add a note that it's still wrong for some cases (as it has been for a
4101 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
4102 %push-parser no longer implies %pure-parser.
4104 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4106 Remove some unnecessary differences between the pull parser code and
4107 the push parser code. This patch enables yynerrs in push mode.
4108 * data/push.c: Reformat M4 a little.
4109 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
4110 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
4111 because push mode is on. Instead, if pure mode is on, move yynerrs
4113 (b4_declare_parser_state_variables): ... here.
4114 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
4115 to yyps->NAME so it can be used in yypush_parse.
4116 (yypush_parse): Don't omit uses of yynerrs in push mode.
4118 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4120 Fix bug such that the first pushed token's value and location are
4121 sometimes overwritten (sometimes by %initial-action) before being used.
4122 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
4123 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
4124 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
4125 more closely mimic the pull parser logic.
4126 Don't copy the pushed token to yychar, yylval, and yylloc until it's
4127 time to read a token, which is after any initialization of yylval and
4129 (gottoken): Rename label to...
4130 (yyread_pushed_token): ... for clarity and to avoid infringing on the
4133 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4135 Rearrange initialization of the parser state variables so that the
4136 skeleton doesn't have to have a copy for pull mode and another for push
4137 mode. This patch also fixes at least a bug such that yylloc was not
4138 initialized (with b4_location_initial_line and
4139 b4_location_initial_column) upon calling yypush_parse. However, that
4140 initialization now overwrites the first token's location;
4141 %initial-action assigning @$ already did the same thing, and both bugs
4142 will be fixed in a later patch.
4143 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
4144 (b4_declare_parser_state_variables): Remove initialization of yytoken,
4145 yyss, yyvs, yyls, and yystacksize.
4146 (yypstate_new): Remove initialization of some yypstate fields: yystate,
4147 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
4149 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
4150 yyps->NAME so it can be used in yypush_parse.
4151 (yyparse or yypush_parse): For yypush_parse, don't print the
4152 "Starting parse" diagnostic for invocations after the first.
4153 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
4154 yypush_parse, only do it for the first invocation.
4155 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
4156 initialization to occur in yypush_parse but only on the first
4159 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
4161 * data/push.c: Add CPP guards around push parser declarations in both
4162 the header and the code file.
4163 In the code file, move the push parser declarations to the same place
4164 they appear in the header file.
4165 Clean up the M4 some, especially the inconsistent underquoting in
4166 some b4_c_function_def and b4_c_function_decl uses.
4168 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
4170 Encapsulate the push parser state variables into an M4 macro so the
4171 push skeleton doesn't have to list them again for pull mode's yyparse.
4172 For push mode, remove yypush_parse's local equivalents of these
4173 variables to eliminate unnecessary copying between the two sets at
4174 run-time. This patch also fixes at least a bug related to multiple
4175 %initial-action invocations in push mode.
4176 * data/push.c (b4_declare_parser_variables): Rename to...
4177 (b4_declare_scanner_communication_variables): ... this for clarity and
4179 (b4_declare_yyparse_variables): Remove and move its contents to the one
4180 spot where it was invoked.
4181 (b4_declare_parser_state_variables): New macro containing the parser
4182 state variables required by push mode.
4183 (struct yypstate): Replace all fields but yynew with
4184 b4_declare_parser_state_variables.
4185 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
4186 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
4187 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
4188 (yyparse or yypush_parse): For yyparse in pull mode, replace local
4189 parser state variable declarations with
4190 b4_declare_parser_state_variables.
4191 Don't initialize parser state variables when calling yypush_parse since
4192 yypstate_new already does that.
4193 Invoke the user's initial action only upon the first yypush_parse
4195 Remove all code that copies between the local parser state variables
4198 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
4200 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
4201 prevent a name collision in a future patch where these names will
4202 sometimes be #define'd.
4203 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
4204 since it no longer has the same name as the existing argument.
4205 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
4207 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
4208 and Joel E. Denny <jdenny@ces.clemson.edu>
4210 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
4211 that the argument is case-insensitive, and there's no `=' here.
4212 For the %skeleton entry, mention that %language is better.
4213 (Bison Options): Likewise for --language and --skeleton. Move the
4214 --skeleton entry so that the `Tuning the parser' section is sorted
4215 alphabetically on long options.
4216 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
4217 %language directive in detail here; cross-reference the %language
4218 documentation instead.
4219 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
4220 `%require "2.3b"' so that the example is always up-to-date.
4221 (Table of Symbols): Add entries for %language and %skeleton.
4222 * examples/extexi (normalize): Instead of replacing every %require
4223 argument with the current Bison version, just substitute for
4224 `@value{VERSION}'. This guarantees that we're testing what actually
4225 appears in the documentation.
4226 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
4227 rather than `@VERSION@'.
4229 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
4231 * NEWS: Reword the %language news a bit, and put it earlier.
4233 * src/getargs.c (skeleton_arg): Last arg is now location const *.
4234 Rewrite to simplify the logic.
4235 (language_argmatch): Likewise.
4236 (program_name): We now own this var.
4237 * src/getargs.h (struct bison_language): Use char[] rather than
4240 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
4242 * src/complain.c (program_name): Remove decl; no longer needed.
4243 * src/main.c (program_name): Remove; now belongs to getargs.
4245 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
4247 * NEWS: Document %language.
4249 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
4251 * data/c-skel.m4, data/c++-skel.m4: New files.
4252 * data/glr.c: Complain on push parsers.
4254 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
4256 (Decl Summary): Document %language and %skeleton.
4257 (Command line): Document -L.
4259 * examples/extexi: Rewrite %require directive.
4260 * examples/calc++/Makefile.am: Pass VERSION to extexi.
4262 * src/files.c (compute_exts_from_gc): Look in language structure
4264 (compute_file_name_parts): Check whether .tab should be added.
4265 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
4266 (language, skeleton_arg, language_argmatch): New.
4267 (long_options): Add --language.
4268 (getargs): Use skeleton_arg, add -L/--language.
4269 * src/getargs.h: Include location.h.
4270 (struct bison_language, language, skeleton_arg, language_argmatch): New.
4271 * src/output.c (prepare): Pick default skeleton from struct language.
4272 Don't dispatch C skeletons here.
4273 * src/parse-gram.y (PERCENT_LANGUAGE): New.
4274 (prologue_declaration): Add "%language" rule, use skeleton_arg.
4275 * src/scan-gram.l ("%language"): New rule.
4277 * tests/calc.at: Test %skeleton and %language.
4278 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
4279 (AT_GLR_IF): Look for %skeleton "glr.cc".
4280 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
4281 (AT_YACC_IF): Reject %language.
4283 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
4285 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
4286 since it wasn't used; only the typedef name 'semantic_type' is needed.
4287 Also, omit trailing white space.
4289 * bootstrap: Sync from coreutils.
4290 (gnulib_extra_files): Add build-aux/announce.gen.
4291 (slurp): Adjust .gitignore files like .cvsignore files.
4292 * build-aux/announce-gen: Remove from CVS, since bootstrap
4295 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
4297 Make %push-parser imply %pure-parser. This fixes several bugs; see
4298 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
4299 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
4301 * data/push.c: Don't bother testing b4_push_if when deciding whether
4302 to expand b4_declare_parser_variables globally.
4303 (yypush_parse): Likewise in here.
4305 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
4306 (yy_reduce_print): Reformat M4 for readability.
4308 2006-12-15 Bob Rossi <bob@brasko.net>
4309 and Joel Denny <jdenny@ces.clemson.edu>
4311 * data/push.c (yypstate): Add typedef, and update all uses of
4312 struct yypstate to just yypstate.
4313 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
4315 2006-12-14 Bob Rossi <bob@brasko.net>
4317 * data/push.c (yypush_parse): Declare prototype regardless of
4320 2006-12-14 Bob Rossi <bob@brasko.net>
4322 * data/push.c (yyparse): Remove the prototype and the #define when in
4325 2006-12-13 Bob Rossi <bob@brasko.net>
4327 * data/push.c (yypstate_init): Rename to...
4328 (yypstate_new): ... this and use b4_c_function_def.
4329 (yypstate_delete): New.
4330 (yypush_parse): Change parameters yynval and yynlloc to be const.
4331 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
4332 yypstate_delete functions.
4334 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
4336 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
4337 strange test case titles. Reported by Bob Rossi.
4339 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
4341 * TODO: Add pointer to Sylvain Schmitz's work on static detection
4342 of potential ambiguities in GLR grammers.
4344 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
4346 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
4347 `bison ', use m4_index instead of m4_substr since chopping up a string
4348 containing M4-special characters causes problems here.
4350 Fix a couple of bugs related to special characters in user-specified
4351 file names, and make it easier for skeletons to compute output file
4352 names with the same file name prefix as Bison-computed output file
4354 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
4355 b4_parser_file_name and b4_spec_defines_file instead of
4356 @output_parser_name@ and @output_header_name@, which are now redundant.
4357 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
4358 b4_parser_file_name, b4_spec_defines_file, and the new
4359 @basename(FILENAME@) instead of @output_parser_name@ and
4360 @output_header_name@, which inappropriately escaped the file names as
4362 * src/files.c (all_but_ext): Remove static qualifier.
4363 (compute_output_file_names): Move `free (all_but_ext)' to...
4364 (output_file_names_free): ... here since all_but_ext is needed later.
4365 * src/files.h (all_but_ext): Extern.
4366 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
4367 exactly what MUSCLE_INSERT_STRING used to do.
4368 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
4369 characters are escaped properly.
4370 * src/output.c (prepare): Define muscle file_name_all_but_ext as
4372 For pkgdatadir muscle, maintain previous functionality by using
4373 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
4374 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
4375 digraphs would never be expanded. Hopefully no one has M4-special
4376 characters in his Bison installation path.
4377 * src/scan-skel.l: Don't parse @output_header_name@ and
4378 @output_parser_name@ anymore since they're now redundant.
4379 In @output, use decode_at_digraphs.
4380 Parse a new @basename command that invokes last_component.
4381 (decode_at_digraphs): New.
4382 (BASE_QPUTS): Remove unused.
4383 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
4384 (Output file name): New tests.
4386 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
4388 Warn about output files that are generated by the skeletons and that
4389 conflict with other output files.
4390 * data/glr.c: Don't generate the header file here when glr.cc does.
4391 * src/files.c (file_names, file_names_count): New static globals.
4392 (compute_output_file_names): Invoke output_file_name_check for files
4393 not generated by the skeletons and remove existing checks.
4394 (output_file_name_check): New function that warns about conflicting
4396 (output_file_names_free): Free file_names.
4397 * src/files.h (output_file_name_check): Declare.
4398 * src/scan-skel.l: Invoke output_file_name_check for files generated by
4400 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
4401 (Conflicting output files): New tests.
4403 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4405 * doc/bison.texinfo: Fix a couple of typos.
4407 2006-12-08 Bob Rossi <bob@brasko.net>
4409 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
4411 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
4413 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
4414 (yypush_parse): Rename yypvars argument to yyps and remove redundant
4416 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
4417 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
4419 2006-12-07 Bob Rossi <bob@brasko.net>
4420 and Joel Denny <jdenny@ces.clemson.edu>
4422 * data/push.c (yypvarsinit): Change return type from void* to struct
4423 yypvars*. No longer cast to void* on return.
4424 (struct yypvars): Remove yylen since it need not be remembered between
4425 yypushparse invocations.
4426 (yypushparse): Don't copy between yylen and pv->yylen.
4428 2006-12-05 Bob Rossi <bob@brasko.net>
4430 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
4431 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
4432 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
4433 (struct yypvars): Remove b4_declare_parser_variables.
4434 (yypvarsinit): Remove init code for removed variables.
4435 (global scope): Do not declare b4_declare_parser_variables if
4437 (yypushparse): Add b4_declare_parser_variables.
4438 Init new local variables, and remove init code for removed
4441 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
4442 and yyparse for other modes.
4443 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
4444 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
4445 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
4446 (AT_PURE_LEX_IF): True if pure or push parser.
4448 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>

4473 * tests/headers.at (export YYLTYPE): Remove the `=' from %name-prefix.
4474 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Likewise.
4475 * tests/output.at (AT_CHECK_OUTPUT): Remove the `=' from all but one
4476 occurrence of each of %file-prefix and %output. Add check for %defines
4478 * tests/reduce.at (Useless Terminals, Useless Nonterminals,
4479 Useless Rules, Reduced Automaton, Underivable Rules, Empty Language):
4480 Remove the `=' from %output.
4482 2006-11-21 Joel E. Denny <jdenny@ces.clemson.edu>
4484 Don't escape $ in test case titles since Autoconf 2.61 now does that
4486 * tests/actions.at (Default %printer and %destructor are not for error
4487 or $undefined): Here.
4488 (Default %printer and %destructor are not for $accept): Here.
4489 * tests/input.at (Invalid $n and @n): Here.
4491 2006-11-20 Joel E. Denny <jdenny@ces.clemson.edu>
4493 Rename <!> to <>. Discussed starting at

4503 * tests/actions.at (Default tagless %printer and %destructor,
4504 Default tagged and per-type %printer and %destructor,
4505 Default %printer and %destructor are not for error or $undefined,
4506 Default %printer and %destructor are not for $accept,
4507 Default %printer and %destructor for mid-rule values): Update.
4508 * tests/input.at (Default %printer and %destructor redeclared,
4509 Unused values with default %destructor): Update.
4511 2006-11-17 Joel E. Denny <jdenny@ces.clemson.edu>

4524 grammar is maintained with Bison's highest standards.
4525 * src/getargs.c: Fix some typos in Doxygen comments.
4527 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
4529 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
4530 later. Reported by Paul Eggert in
4531 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
4532 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
4533 * src/scan-code.l (translate_action): Don't bother invoking
4534 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
4535 (code_scanner_free): Instead of invoking
4536 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,

4544 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
4545 has been called previously for the same key.
4546 (muscle_find): Return storage instead of value so that
4547 --enable-gcc-warnings doesn't produce warnings that the return discards
4548 const. aver that the value and storage are the same since storage
4549 could potentially be NULL when value is not.
4550 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
4553 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4555 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
4556 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
4557 us a slightly cleaner distribution, and also works.
4558 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
4561 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
4562 and Paul Eggert <eggert@cs.ucla.edu>

4567 since they are freed.
4568 * src/files.c: Likewise.
4569 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
4571 (tr): Now operates in-place. All uses changed.
4572 (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
4574 (compute_file_name_parts, compute_output_file_names): Don't store
4575 read-only data in variables that will be freed.
4576 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
4577 src_extension, and header_extension.
4578 (output_file_names_free): New public function to free
4579 spec_verbose_file, spec_graph_file, spec_defines_file,
4580 parser_file_name, and dir_prefix.
4581 * src/getargs.c (getargs): Don't store read-only data in variables that
4583 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
4584 (which previously existed but was unused), and quotearg_free.
4585 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
4586 * src/muscle_tab.c: Likewise.
4587 (muscle_entry): Make the value char const *,
4588 and add a new storage member that is char * and can be freed.
4589 (muscle_entry_free): New private function.
4590 (muscle_init): Use it instead of free.
4591 (muscle_insert, muscle_grow): Update and use new storage member.
4592 (muscle_code_grow): Free the string passed to muscle_grow
4593 since it's not needed anymore.
4594 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
4595 add a new `char *code' member.
4596 ("{...}"): Declare semantic type as code.
4597 * src/scan-code.h (translate_rule_action):
4598 (translate_symbol_action, translate_code, translate_action): Return
4599 `char const *' rather than `char *' since external code should not free
4601 * src/scan-code.l: Likewise.
4602 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
4603 which is "{...}" in the parser.
4604 * tests/Makefile.am (maintainer-check-valgrind): Set
4605 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
4607 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
4609 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
4610 expecting a non-zero exit status sets --leak-check=summary and
4611 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
4612 this case, and we don't want to hear about it.
4614 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4616 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
4617 instead of from the template, to simplify configuration a bit.

4633 declarations): Run tests with and without --warnings=midrule-values.
4635 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
4636 than LIST_FREE directly.
4638 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>

4659 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
4661 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
4662 the parser header file so that gcc doesn't warn.
4664 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
4666 Split the default %destructor/%printer into two kinds: <*> and <!>.

4712 Don't apply the default %destructor/%printer to an unreferenced midrule
4714 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
4715 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
4716 like $@n instead of just @n so that the default %destructor/%printer
4717 logic doesn't see them as user-defined symbols.
4718 (symbol_is_dummy): Check for both forms of the name.
4719 * src/reader.c (packgram): Remove the `$' from each midrule symbol
4720 name for which the midrule value is referenced in any action.

4748 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
4750 Similar to the recently removed %before-header, add %code-top as the
4751 alternative to the pre-prologue. Mentioned at
4752 <http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00063.html>.

4754 * src/parse-gram.y (PERCENT_CODE_TOP): New token.
4755 (prologue_declaration): Move the existing prologue alternatives to...
4756 (grammar_declaration): ... here and add %code-top.

4810 In messages and comments, say e.g., "checked-out sources",
4811 rather than "CVS sources".

4813 for CVS. Don't use grep's -q option.
4814 (slurp): Call it here, in place of CVS-specific code.
4816 2006-10-14 Joel E. Denny <jdenny@ces.clemson.edu>
4818 Fix testsuite for ./configure --enable-gcc-warnings:
4819 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.
4820 Otherwise, gcc 4.1.0 (at least) warns about sign comparisons in
4821 __AT_CHECK_PRINTER_AND_DESTRUCTOR in tests/actions.at.
4822 * test/input.at (Torturing the Scanner): #include <stdlib.h> for abort.

4863 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
4864 variable was sometimes used without being initialized. This
4865 messed up the installation of the INSTALL file in some cases.
4867 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4869 * bootstrap (usage, main program, symlink_to_gnulib): Add option
4870 --copy. Inspired by a suggestion from Bruno Haible.
4872 2006-10-03 Jim Meyering <jim@meyering.net>
4874 * bootstrap: Undo last change to this file, since now gnulib-tool
4875 sticks with the automake default in generating dependencies.
4877 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4879 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than
4880 the old AC_PROG_CC / AM_PROG_CC_STDC combination.
4882 * doc/bison.1: Add copyright notice.

4903 * src/print_graph.c: Include graphviz.h rather than vcg.h.
4904 (static_graph, fgraph): Remove. All uses changed to pass
4905 arguments instead of sharing a static var.
4906 (print_core, print_actions, print_state, print_graph):
4907 Output graphviz format rather than VCG format.
4908 * tests/.cvsignore: Remove *.vcg; add *.dot.
4909 * tests/output.at: Expect *.dot files, not *.vcg files.
4911 * data/Makefile.am (dist_pkgdata_DATA): Add bison.m4; this
4912 accommodates the 2006-10-08 change.
4914 2006-10-11 Bob Rossi <bob@brasko.net>
4916 * data/push.c (yypushparse, yypvarsinit, yypvars): Wrap in b4_push_if.

4924 * data/push.c (yypushparse): Fix memory leak if yymsg is malloced
4925 in a push parser. Reindent slightly to match yacc.c better.
4927 2006-10-11 Bob Rossi <bob@brasko.net>

4941 b4_location_initial_line, p4_parse_param, b4_ints_in, b4_flag_if,
4942 b4_define_flag_if and uses, b4_basename, b4_syncline, b4_user_code,
4943 b4_define_user_cde and uses): Remove.

4953 Fix test failure reported by Tom Lane in
4954 <http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
4955 and try to make such failures easier to catch in the future.
4956 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
4957 that's now the caller's responsibility.
4958 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
4959 Set yychar = YYEOF if it's negative.
4960 * tests/actions.at (yylex): Abort if asked to read past EOF.

4970 Fix problems with translating English-language diagnostics.
4971 * bootstrap: Fix bug introduced in recent bootstrap changes, with
4972 respect to bison-runtime pot generation. The YY_ stuff
4973 wasn't being captured.
4974 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
4975 * po/POTFILES.in: Add src/location.c, src/scan-code.l.
4976 * runtime-po/POTFILES.in: Add data/push.c.
4978 2006-09-29 Paul Eggert <eggert@cs.ucla.edu>
4980 Merge bootstrap changes from coreutils.
4982 2006-09-28 Jim Meyering <jim@meyering.net>
4984 Automatically generated dependencies are important even
4985 when all of the sources in a directory come from gnulib.
4986 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
4987 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
4989 2006-09-23 Jim Meyering <jim@meyering.net>
4991 * bootstrap (gnulib_tool_options): Add "--local-dir gl".
4993 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>

5015 Remove config.h, config.hin, intl (no longer created).
5016 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
5019 Sync bootstrap from coreutils, as follows:
5021 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
5023 * bootstrap (symlink_to_gnulib): New function.
5024 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
5025 to copies-of-gnulib.
5026 (cp_mark_as_generated, slurp, gnulib_files):
5027 Avoid making a copy if it's the same as the old version.
5028 (gnulib_files): Add support for this variable (used by Bison).
5030 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
5032 * src/getargs.c (usage): Rework to use conventions similar to
5033 coreutils, to make translation a bit easier and the code a bit
5034 smaller. Problem reported by Tim Van Holder.
5036 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
5038 Use some of gnulib's new modules, taken from coreutils.
5040 * bootstrap: Sync from coreutils, except add support for gnulib_files.
5041 * bootstrap.conf: New file.
5042 (gnulib_modules): Add configmake, inttypes, unistd.
5043 (XGETTEXT_OPTIONS): Add complain, complain_at,
5044 fatal, fatal_at, warn, warn_at, unexpected_end.
5045 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
5046 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
5048 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
5050 (GNULIB_AUTOCONF_SNIPPET): Remove.
5051 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
5053 * lib/.cvsignore: Add inttypes_.h.
5054 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
5055 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.

5057 no-longer-necessary initializations.
5058 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
5059 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
5060 use the unistd module.
5061 * src/system.h: Likewise.
5062 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
5063 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
5064 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
5065 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
5066 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
5067 * src/system.h: Include inttypes.h unconditionally, now that we
5068 use the inttypes module. Don't bother to include stdint.h, since
5069 inttypes.h now does that for us.
5070 (LOCALEDIR): Remove, now that we use the configmake module.
5071 * src/getargs.c: Include configmake.h.
5072 * src/main.c: Likewise.
5073 * src/output.c: Likewise.
5074 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
5075 not from $abs_top_builddir, since config.h moved.
5078 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
5079 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
5081 * src/parse-gram.y (symbol_declaration): Don't put statements
5082 before declarations; it's not portable to C89.
5083 * src/scan-code.l (handle_action_at): Likewise.
5085 * src/scan-code.l: Always initialize braces_level; the old code
5086 left it uninitialized and therefore had undefined behavior.
5088 Don't attempt to redefine 'assert', since it runs afoul of
5089 systems where standard headers (mistakenly) include <assert.h>.
5090 Instead, define and use our own alternative, called 'aver'.
5091 * src/reader.c: Don't include assert.h, since we no longer
5093 * src/scan-code.l: Likewise.
5094 * src/system.h (assert): Remove, replacing with....
5095 (aver): New function, taking a bool arg. All uses changed.
5096 * src/tables.c (pack_vector): Ensure that aver arg is bool,
5097 not merely an integer.
5099 2006-09-15 Bob Rossi <bob@brasko.net>
5101 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
5102 * data/c.m4 (YYPUSH): New.

5105 * src/getargs.h (push_parser): New declaration.
5106 * src/output.c (prepare): Add macro insertion of `push_flag'.
5107 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
5108 (prologue_declaration): Parse %push-parser.
5109 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
5110 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
5111 list of removed lines from the traces observed.
5112 (AT_CHECK_CALC_LALR): Added push parser tests.
5114 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
5116 * NEWS: Version 2.3a.
5117 * configure.ac (AC_INIT): Likewise.
5119 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
5120 "#define YYSTYPE int" that caused "make maintainer-check" to fail
5121 due to header ordering dependencies. I don't know why the #define
5124 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
5125 runtime cost when YYDEBUG is not defined, and so that some tests
5126 that used to fail now work. Problem and initial suggestion by
5128 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
5129 * data/glr.cc (b4_parser_class_name):
5130 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
5131 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
5132 (yydebug_) [YYDEBUG]: New member.
5133 (yycdebug_): Now defined only if YYDEBUG.
5134 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
5135 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
5136 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
5138 (debug_stream, set_debug_stream, debug_level, set_debug_level):
5139 Define only if YYDEBUG.
5140 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
5142 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
5143 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
5144 AT_CHECK_CALC_GLR_CC that are working now.
5146 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
5148 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
5149 We don't need them in glr.cc, and glr.c defines them.
5150 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
5151 assumes that defining it to anything is the same as defining
5152 it to 1. Problem reported by Paolo Bonzini.
5154 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
5156 * data/c.m4 (b4_null, b4_case): Define.
5157 * src/output.c (prepare_symbols): Use b4_null.
5158 (user_actions_output): Use b4_case.
5160 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
5162 * data/glr.c (b4_shared_declarations): Put start-header first,
5163 before any #includes that we generate, so that feature-test
5164 macros work. Problem reported by Michael Deutschmann in
5165 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
5166 * data/lalr1.cc: Likewise.
5167 * doc/bison.texinfo (Prologue): Document that feature-test macros
5168 should be defined before any Bison declarations.
5169 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
5170 that depend on location.hh after, not before, Bison decls, since
5171 we now include location.hh after the first user prologue.
5173 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
5174 Sander Brandenburg in
5175 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
5176 Also, fix minor white space and comment issues.
5177 (Prologue): Mention that it's better to define feature-test macros
5178 before Bison declarations. Problem reported by Michael Deutschmann.
5180 * README-cvs: Fix typo: "&" should be "&&". Problem reported
5182 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
5183 This adjusts to recent gnulib changes.
5185 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
5187 Finish implementation of per-type %destructor/%printer. Discussed
5189 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
5191 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
5192 * NEWS (2.3+): Add a description of this feature to the default
5193 %destructor/%printer description.
5194 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
5195 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
5196 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
5197 list node contains a semantic type.
5198 * src/symtab.c, src/symtab.h: Extend with a table that associates
5199 semantic types with their %destructor's and %printer's.
5200 (semantic_type_from_uniqstr, semantic_type_get,
5201 semantic_type_destructor_set, semantic_type_printer_set): New functions
5202 composing the public interface of that table.
5203 (symbol_destructor_get, symbol_destructor_location_get,
5204 symbol_printer_get, symbol_printer_location_get): If there's no
5205 per-symbol %destructor/%printer, look up the per-type before trying
5207 * tests/actions.at (Per-type %printer and %destructor): New test case.
5208 * tests/input.at (Default %printer and %destructor redeclared):
5209 Extend to check that multiple occurrences of %symbol-default in a
5210 single %destructor/%printer declaration is an error.
5211 (Per-type %printer and %destructor redeclared, Unused values with
5212 per-type %destructor): New test cases.
5214 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
5216 Require default %destructor/%printer to be declared using
5217 %symbol-default instead of an empty symbol list, and start working on
5218 new per-type %destructor/%printer. Discussed at
5219 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
5220 * NEWS (2.3+): Add %symbol-default to example.
5221 * bison.texinfo (Freeing Discarded Symbols): Likewise.
5222 (Table of Symbols): Add entry for %symbol-default.
5223 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
5224 (generic_symlist, generic_symlist_item): New nonterminals for creating
5225 a list in which each item is a symbol, semantic type, or
5227 (grammar_declaration): Use generic_symlist in %destructor and %printer
5228 declarations instead of symbols.1 or an empty list.
5229 (symbol_declaration, precedence_declaration, symbols.1): Update actions
5230 for changes to symbol_list.
5231 * src/reader.c: Update for changes to symbol_list.
5232 * src/scan-code.l: Likewise.
5233 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
5234 * src/symlist.c, src/symlist.h: Extend such that a list node may
5235 represent a semantic type or a %symbol-default in addition to just an
5236 ordinary symbol. Add switched functions for setting %destructor's and
5238 * tests/actions.at, tests/input.at: Add %symbol-default to all default
5239 %destructor/%printer declarations.
5241 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
5243 Whether the default %destructor/%printer applies to a particular symbol
5244 isn't a question of whether the user *declares* that symbol (in %token,
5245 for example). It's a question of whether the user by any means
5246 *defines* the symbol at all (by simply using a char token, for
5247 example). $end is defined by Bison whereas any other token with token
5248 number 0 is defined by the user. The error token is always defined by
5249 Bison regardless of whether the user declares it with %token, but we
5250 may one day let the user define error as a nonterminal instead.
5251 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
5252 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
5253 the meaning of "user-defined".
5254 * tests/actions.at (Default %printer and %destructor for user-declared
5255 end token): Rename to...
5256 (Default %printer and %destructor for user-defined end token): ...
5259 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
5260 computation of whether to apply the default, don't maintain a list of
5261 every Bison-defined symbol. Instead, just check for a first character
5262 of '$', which a user symbol cannot have, and check for the error token.
5264 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
5266 Don't apply the default %destructor or %printer to the error token,
5267 $undefined, or $accept. This change fits the general rule that the
5268 default %destructor and %printer are only for user-declared symbols,
5269 and it solves several difficulties that are described in the new test
5271 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
5272 * tests/actions.at (Default %printer and %destructor are not for error
5273 or $undefined, Default %printer and %destructor are not for $accept):
5276 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
5278 Allow %start after the first rule.
5279 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
5280 when parsing the first rule.
5281 (check_and_convert_grammar): Search for it here after all grammar
5282 declarations have been parsed. Skip midrules, which have dummy LHS
5284 * src/symtab.c (symbol_is_dummy): New function.
5285 * src/symtab.h (symbol_is_dummy): Declare it.
5286 * tests/input.at (%start after first rule): New test.
5288 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
5290 Redo some of the previous commit: add back the ability to use
5291 non-aliased/undeclared string literals since it might be useful to
5292 those declaring %token-table.
5293 * src/reader.c (check_and_convert_grammar): Undo changes in previous
5294 commit: don't worry about complaints from symbols_pack.
5295 * src/symtab.c (symbol_new, symbol_class_set,
5296 symbol_check_alias_consistency): Undo changes in previous commit: count
5297 each string literal as a new symbol and token, assign it a symbol
5298 number, and don't complain about non-aliased string literals.
5299 (symbols_pack): Since symbol_make_alias still does not decrement symbol
5300 and token counts but does still set aliased tokens to the same number,
5301 symbol_pack_processor now leaves empty slots in the symbols array.
5303 * tests/regression.at (Undeclared string literal): Remove test case
5304 added in previous commit since non-aliased string literals are allowed
5306 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
5307 remove unnecessary string literal declarations.
5308 * tests/sets.at (Firsts): Likewise.
5310 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
5312 Don't allow an undeclared string literal, but allow a string literal to
5313 be used before its declaration.
5314 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
5315 symbols_pack complained.
5316 * src/symtab.c (symbol_new): Don't count a string literal as a new
5318 (symbol_class_set): Don't count a string literal as a new token, and
5319 don't assign it a symbol number since symbol_make_alias does that.
5320 (symbol_make_alias): It's not necessary to decrement the symbol and
5321 token counts anymore. Don't assume that an alias declaration occurs
5322 before any uses of the identifier or string, and thus don't assert that
5323 one of them has the highest symbol number so far.
5324 (symbol_check_alias_consistency): Complain if there's a string literal
5325 that wasn't declared as an alias.
5326 (symbols_pack): Bail if symbol_check_alias_consistency failed since
5327 symbol_pack asserts that every token has been assigned a symbol number
5328 although undeclared string literals have not.
5329 * tests/regression.at (String alias declared after use, Undeclared
5330 string literal): New test cases.
5331 (Characters Escapes, Web2c Actions): Declare string literals as
5333 * tests/sets.at (Firsts): Likewise.
5335 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
5337 In the grammar scanner, STRING_FINISH unclosed constructs and return
5338 them to the parser in order to improve error messages.
5339 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
5340 SC_BRACED_CODE, SC_PROLOGUE): Implement.
5341 * tests/input.at (Unclosed constructs): New test case.
5342 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
5345 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
5348 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
5350 Handle string aliases for character tokens correctly.
5351 * src/symtab.c (symbol_user_token_number_set): If the token has an
5352 alias, check and set its alias's user token number instead of its own,
5353 which is set to indicate the alias. Previously, every occurrence of
5354 the character token in the grammar overwrote that alias indicator with
5356 * tests/input.at (String aliases for character tokens): New test.
5358 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
5360 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
5362 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
5364 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
5365 to prevent failures when building on older platforms.
5366 Check for autopoint failure.
5367 Set XGETTEXT_OPTIONS to values that check for C format strings,
5368 so that translators are warned about them (this also helps
5369 prevent core dumps).
5371 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
5372 function, since it simplifies our code a bit.
5374 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
5375 rather than -W, so we don't get bogus warnings about sign comparisons.
5376 Add -Wpointer-arith, since that warning is useful (it reports code
5377 that does not conform to C89 and that some compilers reject).
5378 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
5379 since it's no longer needed.
5381 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
5383 Clean up scanners a bit.
5384 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
5385 definitions so gcc won't warn when obstack_for_string is unused.
5386 * src/scan-code.l: config.h and system.h are already #include'd by
5387 scan-code-c.c, so get rid of them here.
5388 * src/scan-gram.l: Likewise.
5389 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
5390 definitions rather than duplicating the rest of it.
5391 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
5393 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
5395 Suppress signed/unsigned comparison warnings for yycheck.
5396 * data/c.m4 (b4_safest_int_type): New macro.
5397 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
5398 a signed int type, cast it to b4_safest_int_type first.
5399 * data/yacc.c: Likewise.
5400 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
5403 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
5405 * doc/bison.texinfo: Fix some typos.
5407 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
5409 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
5410 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
5412 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
5413 the latest gnulib does this a different way.
5414 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
5415 translation was patched, so stop omitting it.
5417 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
5419 Enable declaration of default %printer/%destructor. Make the parser
5420 use these for all user-declared grammar symbols for which the user does
5421 not declare a specific %printer/%destructor. Thus, the parser uses it
5422 for token 0 if the user declares it but not if Bison generates it as
5423 $end. Discussed starting at
5424 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
5425 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
5427 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
5428 * NEWS (2.3+): Mention.
5429 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
5430 declare a %destructor for a mid-rule's semantic value. It's just
5431 impossible to declare one specific to it.
5432 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
5433 code. Describe default %destructor form.
5434 * src/parse-gram.y (grammar_declaration): Parse default
5435 %printer/%destructor declarations.
5436 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
5437 and symbol_destructor_location_get rather than accessing the destructor
5438 and destructor_location members of struct symbol.
5439 (symbol_printers_output): Likewise but for %printer's.
5440 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
5442 * src/symtab.c (default_destructor, default_destructor_location,
5443 default_printer, default_printer_location): New static global
5444 variables to record the default %destructor and %printer.
5445 (symbol_destructor_get, symbol_destructor_location_get,
5446 symbol_printer_get, symbol_printer_location_get): New functions to
5447 compute the appropriate %destructor and %printer for a symbol.
5448 (default_destructor_set, default_printer_set): New functions to set the
5449 default %destructor and %printer.
5450 * src/symtab.h: Prototype all those new functions.
5451 * tests/actions.at (Default %printer and %destructor): New test to
5452 check that the right %printer and %destructor are called, that they're
5453 not called for $end, and that $$ and @$ work correctly.
5454 (Default %printer and %destructor for user-declared end token): New
5455 test to check that the default %printer and %destructor are called for
5456 a user-declared end token.
5457 * tests/input.at (Default %printer and %destructor redeclared, Unused
5458 values with default %destructor): New tests to check related grammar
5459 warnings and errors.
5461 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
5463 Clean up handling of %destructor for the end token (token 0).
5464 Discussed starting at
5465 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
5467 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
5469 Make the skeletons consistent in how they pop the end token and invoke
5471 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
5472 state, which has token number 0, since this would invoke the
5473 %destructor for the end token.
5474 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
5475 until after shifting the end token, or else it won't be popped.
5476 * data/yacc.c (yyparse): Likewise.
5478 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
5479 it's the end token. Upon termination, destroy an unshifted lookahead
5480 even when it's the end token.
5481 * data/lalr1.cc (yy::parser::parse): Likewise.
5482 * data/yacc.c (yyparse): Likewise.
5484 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
5485 value warnings for the end token when the user gives the end token a
5488 * tests/actions.at (Printers and Destructors): Test all the above.
5490 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
5492 Update to latest gnulib and gettext versions.
5493 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
5495 (gnulib_files): Add m4/warning.m4. Don't worry about files
5496 overwritten by autopoint.
5497 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
5498 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
5500 Don't use autoreconf; instead, invoke autopoint etc. by hand,
5501 so that we can remove the intl files at a better time.
5502 (intl_files_to_remove): Remove aclocal.m4, since it gets
5503 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
5504 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
5505 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
5506 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
5507 Remove datarootdir hack; no longer needed.
5508 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
5509 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
5510 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
5512 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
5513 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
5515 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
5517 * bootstrap: Adjust to today's change to gnulib-tool by invoking
5518 it with --assume-autoconf='latest-stable'.
5520 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
5522 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
5523 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
5525 * src/muscle_tab.h (muscle_grow): Replace the header comments with
5526 those from muscle_tab.c since the old ones are misleading.
5528 2006-07-13 Akim Demaille <akim@epita.fr>
5530 Support %define "KEY" {VALUE}.
5531 * src/scan-code.h, src/scan-code.l (translate_action)
5532 (translate_rule_action, translate_symbol_action, translate_code):
5533 Return char *, not const char *.
5534 * src/parse-gram.y (declaration): Rename as...
5535 (prologue_declaration): this.
5536 (string_content): Remove this nonterminal, use STRING.
5537 (braceless, content, content.opt): New nonterminal.
5539 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
5541 * src/scan-gram.l (getargs.h): Don't include it.
5543 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
5545 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
5546 rather than a for-loop that declares a local bool variable. This
5547 should work around a compatibility problem with a Cray x1e C++
5548 compiler reported by Hung Nguyen in
5549 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
5550 The for-loop was introduced in the 2004-11-17 change but I don't
5551 know why it was needed.
5553 2006-07-12 Akim Demaille <akim@epita.fr>
5555 * data/c.m4: Comment changes.
5557 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
5559 * src/complain.c (error_message, ERROR_MESSAGE): New.
5561 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
5562 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
5564 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
5566 * NEWS: Instead of %union, you can define and use your own union type
5567 YYSTYPE if your grammar contains at least one <type> tag.
5568 Your YYSTYPE need not be a macro; it can be a typedef.
5569 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
5570 (Union Decl, Decl Summary): Document this.
5571 * data/glr.c (YYSTYPE): Implement this.
5572 * data/glr.cc (YYSTYPE): Likewise.
5573 * data/lalr1.cc (YYSTYPE): Likewise.
5574 * data/yacc.c (YYSTYPE): Likewise.
5575 * src/output.c (prepare): Output tag_seen_flag.
5576 * src/parse-gram.y (declaration, grammar_declaration):
5577 Use 'union_seen' rather than 'typed' to determine whether
5578 %union has been seen, since grammars can now be typed without
5580 (symbol_declaration, type.opt, symbol_def):
5581 Keep track of whether a tag has been seen.
5582 * src/reader.c (union_seen, tag_seen): New vars.
5584 * src/reader.h (union_seen, tag_seen, typed): Likewise.
5585 * src/scan-code.l (untyped_var_seen): New variable.
5586 (handle_action_dollar): Adjust to above changes.
5587 (handle_action_dollar, handle_action_at):
5588 Improve overflow checking for outlandish numbers.
5589 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
5590 avoid new diagnostics generated by above changes.
5591 * tests/regression.at (YYSTYPE typedef): Add test to check
5592 for type tags without %union.
5594 * src/symlist.c (symbol_list_length): Return int, not unsigned
5595 int, since callers expect int. This may need to get revisited
5596 once we have proper integer overflow checking.
5598 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
5599 object is now static.
5601 * src/getargs.c (flags_argmatch): Return void, not int,
5602 to pacify ./configure --enable-gcc-warnings.
5604 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
5605 since last_string is already defined to FLEX_PREFIX (last_string).
5607 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
5609 Implement --warnings/-W.
5610 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
5612 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
5614 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
5615 (warnings_args, warnings_types): New.
5616 (getargs, short_options, long_options): Accept -W/--warnings.
5617 Sort the options by alphabetical order, upper case letter right
5618 before its lower case.
5620 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
5622 Change %merge result type clash warnings to errors. Discussed at
5623 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
5624 * src/reader.c (record_merge_function_type): Use complain_at.
5625 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
5626 declared later): Update test case results.
5628 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
5630 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
5631 to be in alphabetical order.
5632 (trace_args): Spelling fixes.
5634 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
5636 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
5637 so they don't collide with user-defined macros.
5638 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
5639 this was never guaranteed, and now that we're using gnulib stdint,
5640 which defines int_fast16_t to long int, the problem is exposed.
5642 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
5644 * data/c.m4 (b4_basename): Simplify a bit, since we don't
5645 need the full POSIX semantics (and weren't implementing them
5648 Adjust to Autoconf 2.60 and today's gnulib.
5649 * bootstrap (gnulib_modules): Add stdint.
5650 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
5651 no longer copies it.
5652 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
5653 since stdint needs the former and wcwidth (which is now required
5654 by mbswidth) needs the latter.
5655 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
5656 work around a compatibility glitch between gettext 0.14.6 and
5658 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
5659 Do not check for uintptr_t, since new stdint module does the right
5661 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
5662 Add stdint.h, stdint_.h, wcwidth.h.
5663 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
5664 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
5665 stdint.m4, wchar_t.m4, wcwidth.m4.
5666 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
5667 usual order for ../lib/*.h files.
5668 (file_name_split): Use last_component, not base_name, to adjust
5670 * src/parse-gram.h: Include <strverscmp.h> in the usual order
5671 for ../lib/*.h files.
5672 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
5673 Define unconditionally, since we now assume the stdint module.
5674 * src/scan-skel.l: Include <dirname.h>.
5675 (BASE_QPUTS): Use last_component, not base_name.
5676 * src/system.h: Include <unlocked-io.h> in the usual order
5677 for ../lib/*.h files. Include <stdint.h> unconditionally,
5678 since we now use the stdint module.
5679 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
5680 HAVE_UINTPTR_T, since we now use the stdint module.
5681 (base_name): Remove decl, since files now include <dirname.h>
5684 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
5686 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
5688 * data/yacc.c, data/glr.c, data/location.cc: Use them.
5689 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
5691 * tests/calc.at: Adjust.
5693 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
5695 * data/c.m4 (b4_basename): New.
5696 (b4_syncline): Also output the location of its invocation (from
5698 (b4_user_action, b4_define_user_action, b4_user_actions)
5699 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
5700 (b4_user_stype): New.
5701 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
5703 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
5705 In the grammar file, the first column is 1 not 0 on the first line as
5706 on every other line.
5707 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
5708 * tests/input.at (Torturing the Scanner): Update output.
5710 * src/scan-gram.l (scanner_cursor): Declare it static.
5712 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
5714 In warnings, say "previous declaration" rather than "first
5716 * src/symtab.c (redeclaration): Do that here.
5717 * src/reader.c (record_merge_function_type): In the case of a result
5718 type clash, report the previous declaration rather than the very first
5719 one in the grammar file.
5720 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
5721 declared later): Add a third declaration to check this behavior.
5722 * tests/input.at (Incompatible Aliases): Update output.
5724 2006-06-27 Akim Demaille <akim@epita.fr>
5726 * doc/Doxyfile.in: New.
5727 * doc/Makefile.am: Use it.
5728 * src/lalr.h, src/symtab.h: Initial doxygenation.
5730 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
5732 Don't miss %merge result type warnings just because the LHS types are
5733 declared after the %merge. This continues the effort of the previous
5735 * src/reader.c (get_merge_function): Don't set the merger type yet.
5736 (record_merge_function_type): New function for setting the merger type
5737 and checking for clashes.
5738 (grammar_current_rule_merge_set): Set the location of the %merge for
5740 (packgram): Invoke record_merge_function_type for each rule now that
5741 all symbol type declarations have been parsed.
5742 * src/reader.h (merger_list.type_declaration_location): New member
5743 storing the location of the first %merge from which the type for this
5744 merging function was derived.
5745 * src/symlist.h (symbol_list.merger_declaration_location): New member
5746 storing the location of a rule's %merge, if any.
5747 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
5748 declared later): New test to catch the error fixed by the above patch.
5750 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
5752 Get action warnings (grammar_rule_check) right even when symbol
5753 declarations appear after the rules. Discussed at
5754 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
5756 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
5757 Don't mistake the type of $$ in a midrule to be that of its parent
5759 * src/reader.c (grammar_current_rule_end): Don't invoke
5760 grammar_rule_check yet since not all symbol declarations may have been
5762 (grammar_midrule_action): Likewise.
5763 Don't record whether the midrule's $$ has been used yet since actions
5764 haven't been translated yet.
5765 Record the midrule's parent rule and its RHS index within the parent
5767 (grammar_current_rule_action_append): Don't translate the action yet
5768 since not all symbol declarations may have been parsed yet and, thus,
5769 warnings about types for $$, $n, @$, and @n can't be reported yet.
5770 (packgram): Translate the action and invoke grammar_rule_check now that
5771 all symbol declarations have been parsed.
5772 * src/scan-code.l (handle_action_dollar): Now that this is invoked
5773 after parsing the entire grammar file, the symbol list here in the case
5774 of a midrule is actually the midrule's empty RHS, so reference its
5775 parent rule's RHS where necessary.
5776 On the other hand, now that you can already know it's a midrule, you
5777 aren't forced to think $$ has the same type as its parent rule's $$.
5778 (handle_action_at): In the case of a midrule, reference the parent rule
5780 * src/symlist.c (symbol_list_new): Initialize new midrule-related
5782 (symbol_list_length): Now that this is invoked after all rules have
5783 been parsed, a NULL symbol (rather than a NULL symbol list node)
5784 terminates a rule. symbol_list_print already does this correctly.
5785 * src/symlist.h (symbol_list.midrule_parent_rule,
5786 symbol_list.midrule_parent_rhs_index): New members so that midrules can
5787 remember their relationships with their parents.
5788 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
5789 fixed by the above patch.
5790 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
5792 (Unused values): ... this old test case and...
5793 (Unused values before symbol declarations): ... this new test case.
5794 This one is the same as `Unused values' except that all symbol
5795 declarations appear after the rules in order to catch the rest of the
5796 errors fixed by the above patch.
5798 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
5801 * src/reader.c (current_rule): Declare it static since it's no longer
5802 used outside this file.
5803 (grammar_current_rule_action_append): Remove redundant arguments from
5804 translate_rule_action invocation.
5805 * src/reader.h (current_rule): Remove this unused extern.
5806 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
5807 * src/scan-code.l (translate_rule_action): Likewise.
5809 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
5811 Clean up yesterday's patch.
5812 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
5814 * src/reader.c (grammar_current_rule_action_append): ... here for
5815 consistency with grammar_current_rule_symbol_append.
5816 * tests/regression.at (Braced code in declaration in rules section):
5817 Make yyerror and yylex static as usual.
5819 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
5821 Fix bug that mistakes braced code in a declaration in the rules section
5822 to be a rule action. Mentioned at
5823 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
5824 * src/scan-gram.l: Move midrule action detection from the start of the
5825 scanning of any braced code to...
5826 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
5827 action. For readability, use $2 and @2 rather than the equivalent
5829 * tests/regression.at (Braced code in declaration in rules section):
5830 New test to catch the error fixed by the above patch.
5832 Work on code readability some.
5833 * src/scan-code.l (current_rule): Get rid of this misleading and
5834 redundant declaration: it's actually extern'ed in reader.h.
5835 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
5836 translate_action): Add a rule argument and use it instead of the global
5838 (translate_rule_action): This already receives current_rule through an
5839 argument, so pass it on to translate_action instead of assigning
5840 current_rule to current_rule.
5841 (translate_symbol_action, translate_code): Pass rule = NULL to
5844 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
5846 Rename %before-definitions to %start-header and %after-definitions to
5847 %end-header. Don't use these declarations to separate pre-prologue
5848 blocks from post-prologue blocks. Add new order-independent
5849 declarations %before-header and %after-header as alternatives to the
5850 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
5851 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
5852 * NEWS (2.3+): Update for these changes.
5853 * data/glr.c (b4_before_definitions): Update to...
5854 (b4_start_header): ... this.
5855 (b4_after_definitions): Update to...
5856 (b4_end_header): ... this.
5857 * data/glr.cc: Likewise.
5858 * data/lalr1.cc: Likewise.
5859 * data/yacc.c: Likewise.
5860 * doc/bison.texinfo (The prologue): Update names, and replace remaining
5861 prologue blocks with %*-header declarations.
5862 (Calc++ Parser): Likewise.
5863 (Decl Summary): Update names.
5864 (Table of Symbols): Update description.
5865 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
5866 (PERCENT_END_HEADER): ... this.
5867 (PERCENT_BEFORE_DEFINITIONS): Update to...
5868 (PERCENT_START_HEADER): ... this.
5869 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
5870 (declaration): Update token names and m4 macro names.
5871 When parsing %end-header and %start-header, invoke translate_code
5872 before muscle_code_grow, and no longer set global booleans to remember
5873 whether these declarations have been seen.
5874 Parse new %after-header and %before-header.
5875 * src/reader.c (before_definitions, after_definitions): Remove.
5876 (prologue_augment): Accept a new bool argument to specify whether to
5877 augment the pre-prologue or post-prologue.
5878 * src/reader.h (before_definitions, after_definitions): Remove these
5880 (prologue_augment): Add new bool argument.
5881 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
5882 (PERCENT_END_HEADER): ... this.
5883 (PERCENT_BEFORE_DEFINITIONS): Update to...
5884 (PERCENT_START_HEADER): ... this.
5885 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
5886 * tests/actions.at (Printers and Destructors): Update names.
5888 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
5890 Add comparison operators for C++ location classes. Discussed at
5891 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
5892 * data/c++.m4 (b4_define_location_comparison): New boolean %define
5893 declaration indicating whether filename_type has an operator==. If
5894 filename_type is `std::string', it defaults to `1', `0' otherwise.
5895 * data/location.cc: Iff b4_define_location_comparison is `1', add
5896 operator== and operator!= for class position and for class location.
5899 * src/scan-action.l: Remove unused file.
5900 * src/symtab.c (symbol_printer_set): Use printer_location not
5901 destructor_location.
5902 * src/symtab.h (struct symbol): Replace incorrect source comment for
5904 * tests/input.at (Incompatible Aliases): Update output with correct
5907 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
5909 Don't put the pre-prologue in the header file. For the yacc.c code
5910 file and the glr.c header and code files, move the pre-prologue before
5911 the token definitions. Add new %before-definitions and
5912 %after-definitions to declare code that will go in both the header file
5913 and code file. Discussed at
5914 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
5915 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
5917 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
5918 * NEWS (2.3+): Describe these changes.
5919 * data/glr.c (b4_pre_prologue): Move from within to before...
5920 (b4_shared_declarations): ... this.
5921 Add new b4_before_definitions before b4_token_enums.
5922 Add new b4_after_definitions at the end.
5923 * data/glr.cc (b4_pre_prologue): Replace with...
5924 (b4_before_definitions): ... this in the header file.
5925 (b4_after_definitions): New near the end of the header file.
5926 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
5927 code file right before including the header file.
5928 (b4_before_definitions): New in the previous position of
5929 b4_pre_prologue in the header file.
5930 (b4_after_definitions): New near the end of the header file.
5931 * data/yacc.c: Clean up some m4 quoting especially in the header file.
5932 (b4_token_enums_defines): In the code file, move to right before
5933 YYSTYPE for consistency with the header file.
5934 (b4_before_definitions): New right before b4_token_enums_defines in
5935 both the header and code file.
5936 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
5937 header and code file.
5938 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
5939 of prologues for %union dependencies.
5940 (Decl Summary): In %defines description, mention the effect of
5941 %before-definitions and %after-definitions on the header file.
5942 (Calc++ Parser): Forward declare driver in a %before-definitions rather
5943 than in the pre-prologue so that make check succeeds.
5944 (Table of Symbols): Add entries for %before-definitions and
5946 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
5947 %before-definitions.
5948 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
5949 (declaration): Parse those declarations and append to
5950 b4_before_definitions and b4_after_definitions, respectively.
5951 * src/reader.c (before_definitions, after_definitions): New bools to
5952 track whether those declarations have been seen.
5953 (prologue_augment): Add to the post-prologue if %union,
5954 %before-definitions, or %after-definitions has been seen.
5955 * src/reader.h (before_definitions, after_definitions): New extern's.
5956 * src/scan-gram.l: Scan the new declarations.
5957 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
5958 prologue block in a %before-definitions or a %after-definitions based
5959 on whether the %union is declared.
5960 * tests/regression.at (Early token definitions with --yacc, Early token
5961 definitions without --yacc): Move tests for token definitions into the
5962 post-prologue since token names are no longer defined in the
5965 2006-06-20 Akim Demaille <akim@epita.fr>
5967 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
5968 (symbol_get): Use it.
5969 * src/parse-gram.y: Use it.
5971 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
5973 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
5974 build succeeds when configured with --enable-gcc-warnings.
5976 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5978 * src/parse-gram.y (char_name): New function.
5979 (CHAR, STRING, string_content): For %printer, properly escape.
5980 (ID): Prefer fputs to fprintf.
5981 (id): Reindent to be consistent with other rules.
5982 Properly quote char.
5984 The Translation Project changed its way of publishing translations
5985 to maintainers. I haven't received any responses to my request
5986 for supporting the old way, or for documenting the new way. I
5987 have modified 'bootstrap' to use screen scraping
5988 (in this case, HTML scraping). This is unreliable and inelegant,
5989 but I don't see any better way. Yuck.
5990 * bootstrap (TP_URL, WGET_COMMAND): New vars.
5991 (get_translations): New function, which uses HTML scraping to
5992 deduce locations of latest translations.
5993 Use this function to grab both bison and bison-runtime .po files.
5994 Don't bother priming the pump for the runtime-po domain any more,
5995 as it's now translated better than bison is.
5997 2006-06-19 Akim Demaille <akim@epita.fr>
5999 * src/scan-gram.l: No longer "parse" things after `%union' until
6000 `{'. Rather, return a single "%union" token.
6001 No longer make symbols: return strings, and leave the conversion
6002 to symbols to the parser.
6003 (SC_PRE_CODE, token_type): Remove.
6004 * src/parse-gram.y (%union): New field `character'.
6007 (ID, ID_COLON): Now that the scanner no longer makes them
6008 identifiers, adjust all uses to invoke symbol_get.
6009 (id_colon): New, wraps the conversion from string to symbol.
6010 (%union): Accept a possible union_name.
6011 (symbol): Now can be a char.
6012 * data/c.m4 (b4_union_name): Leave a default value.
6013 * data/glr.c, data/yacc.c: Use it.
6015 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
6017 For associating token numbers with token names for "yacc.c", don't use
6018 #define statements unless `--yacc' is specified; always use enum
6019 yytokentype. Most important discussions start at:
6020 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
6021 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
6023 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
6024 * NEWS (2.3+): Mention.
6025 * data/c.m4 (b4_yacc_if): New.
6026 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
6028 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
6029 on token name definitions.
6030 * src/getargs.c (usage): Capitalize `Yacc' in English.
6031 * src/output.c (prepare): Define b4_yacc_flag.
6032 * tests/regression.at (Early token definitions): Test that tokens names
6033 are defined before the pre-prologue not just before the post-prologue.
6034 Remove this test case and copy to...
6035 (Early token definitions with --yacc): ... this to test #define's.
6036 (Early token definitions without --yacc): ... and this to test enums.
6038 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
6040 * NEWS: Reword the post-2.3 change to not be so optimistic about
6041 removing the old "look-ahead" spelling.
6042 Update previous look-ahead/lookahead change reports.
6043 * REFERENCES: look-ahead -> lookahead (since that's
6044 what he actually wrote).
6045 * doc/refcard.tex: look ahead -> lookahead,
6046 look-ahead -> lookahead
6048 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
6050 For consistency, use `lookahead' instead of `look-ahead' or
6051 `look_ahead'. Discussed starting at
6052 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00049.html>
6054 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00017.html>.
6055 * NEWS: For the next release, note the change to `--report'.
6056 * TODO, doc/bison.1: Update English.
6057 * doc/bison.texinfo: Update English.
6058 (Understanding Your Parser, Bison Options): Document as
6059 `--report=lookahead' rather than `--report=look-ahead'.
6060 * src/conflicts.c: Update English in comments.
6061 (lookahead_set): Rename from look_ahead_set.
6062 (flush_reduce): Rename argument look_ahead_tokens to lookahead_tokens.
6063 (resolve_sr_conflict): Rename local look_ahead_tokens to
6064 lookahead_tokens, and update other uses.
6065 (flush_shift, set_conflicts, conflicts_solve, count_sr_conflicts,
6066 count_rr_conflicts, conflicts_free): Update uses.
6067 * src/getargs.c (report_args): Move "lookahead" before alternate
6069 (report_types): Update uses.
6070 (usage): For `--report' usage description, state `lookahead' spelling
6071 rather than `look-ahead'.
6072 * src/getargs.h (report.report_lookahead_tokens): Rename from
6073 report_look_ahead_tokens.
6074 * src/lalr.c: Update English in comments.
6075 (compute_lookahead_tokens): Rename from compute_look_ahead_tokens.
6076 (state_lookahead_tokens_count): Rename from

6125 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
6127 * TODO: Add request from Nelson H. F. Beebe to be able to install
6128 Bison without installing the yacc script.
6130 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
6132 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
6133 and yytext if they're already #define'd.
6134 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...

6144 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
6145 loc argument as it shadows a global.
6146 * src/scan-gram.l: Remove stray comma that prevents boundary_set
6149 * src/.cvsignore: Add scan-code.c.
6151 2006-06-07 Akim Demaille <akim@epita.fr>
6153 * src/scan-gram.l: Move the "add a trailing ; to actions" code
6155 * src/scan-code.l: here.

6163 2006-06-06 Akim Demaille <akim@epita.fr>
6165 Extract the parsing of user actions from the grammar scanner.
6166 As a consequence, the relation between the grammar scanner and
6167 parser is much simpler. We can also split "composite tokens" back
6169 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
6170 * src/scan-gram.l (add_column_width, adjust_location): Move to and
6172 * src/location.h, src/location.c (add_column_width)
6173 (location_compute): these.
6174 Fix the column count: the initial column is 0.
6175 (location_print): Be robust to ending column being 0.
6176 * src/location.h (boundary_set): New.
6177 * src/main.c: Adjust to scanner_free being renamed as
6179 * src/output.c: Include scan-code.h.
6180 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
6182 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
6183 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
6184 which is now, again, a separate token.
6185 Adjust all dependencies.
6186 Whereever actions with $ and @ are used, use translate_code.
6187 (action): Remove this nonterminal which is now useless.
6188 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
6189 (grammar_current_rule_action_append): Use translate_code.

6196 (YY_DECL): Rename as...
6198 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
6199 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):

6207 (increment_rule_length): Remove.
6208 (last_braced_code_loc): Rename as...
6209 (gram_last_braced_code_loc): this.
6210 Adjust to the changes of the parser.
6211 Move all the handling of $ and @ into...
6212 * src/scan-code.l: here.
6213 * src/scan-gram.l (handle_dollar, handle_at): Remove.

6226 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
6228 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
6229 Use Akim's wording from
6230 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
6232 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
6234 Between Bison releases, manually append `+' to the previous Bison
6235 release number, and use that as a signal to automatically print the
6236 ChangeLog's CVS Id keyword from --version. Discussed starting at
6237 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
6238 * ChangeLog: Add Id header.
6239 * configure.ac (AC_INIT): Append `+' to `2.3'.
6240 * src/.cvsignore: Add revision.c.
6241 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
6242 (BUILT_SOURCES): Add revision.c.
6243 (revision.c): New target rule. This file defines a new global variable
6244 named revision. It initializes it with either the Id from ChangeLog
6245 or, if VERSION doesn't contain `+', with the empty string.
6246 * src/getargs.c (version): Print the value of revision.
6247 * src/revision.h: Extern revision.
6249 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
6251 * NEWS: Version 2.3.
6252 * configure.ac (AC_INIT): Likewise.
6254 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
6256 * data/glr.c (YYRECOVERING): Define to be a function-like macro
6257 with no arguments, not as an object-like macro. This is for
6258 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
6259 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
6260 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
6263 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
6265 * src/getargs.c (usage): Back out yesterday's modification of the
6266 --help output so that we don't have to wait for translation before
6269 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
6271 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
6272 Problem reported by Akim Demaille.
6274 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
6276 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
6278 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
6280 * data/yacc.c (yy_reduce_print): Omit trailing white space in
6281 generated source code. Problem reported by Frans Englich in
6282 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
6284 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
6286 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
6287 shell, not within 'make', so that 'make' by an ordinary builder
6288 (using GNU make) does not worry about configuring gzip. This also
6289 works around a bug reported independently by Keith Thompson and by
6290 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
6291 stderr rather than stdout, messing up the build logs.
6293 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
6295 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
6296 to make sure that YYID will never be unused. This fixes a 'make
6297 maintainer-check' failure caused by the recent changes to the 'Trivial
6298 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
6300 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
6302 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
6304 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
6305 state before an empty RHS is always resolved here. Only the location
6306 of that state is guaranteed to be resolved, and that's enough. This
6307 fixes the remaining bug reported by Derek M. Jones in
6308 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
6309 * tests/glr-regression.at (Uninitialized location when reporting
6310 ambiguity): Test the above case.
6311 Also, the embedded comments in this test case claim it checks the case
6312 of an empty RHS that has inherited the initial location. However, the
6313 corresponding LHS was already resolved, so yyresolveLocations didn't
6314 actually have reason to modify it. Fix this by forcing
6315 nondeterministic operation at the beginning of the parse.
6317 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
6319 * data/c.m4 (b4_yy_symbol_print_generate):
6320 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
6321 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
6322 of the bugs reported today by Derek M Jones in
6323 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
6324 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
6325 defined to be a type name without parens or brackets.
6326 (Location Type): Similarly for YYLTYPE.
6327 * tests/regression.at (Trivial grammars): Put in a test for this
6328 bug that will be caught by 'make maintainer-check' (though not,
6329 alas, by 'make check' unless your compiler is picky).
6331 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
6333 * NEWS: Version 2.2.
6334 * configure.ac (AC_INIT): Likewise.
6336 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
6338 * data/glr.c (yyreportTree): Make room in yystates for the state
6339 preceding the RHS. This fixes the segmentation fault reported by Derek
6341 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
6342 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
6343 to the user. Reported for yyreportTree by Derek M. Jones later in the
6345 * THANKS: Add Derek M. Jones.
6346 Update my email address.
6347 Fix typo in Steve Murphy's name.
6349 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
6351 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
6352 checking against YYLAST that caused the parser to miss a potential
6353 alternative in its diagnostic.
6354 Problem reported by Maria Jose Moron Fernandez in
6355 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
6356 * data/lalr1.cc (yysyntax_error_): Likewise.
6357 * data/yacc.c (yysyntax_error): Likewise.
6358 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
6359 tokens, in case we run into an older C compiler.
6360 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
6361 Use them to check for the off-by-one error fixed above.
6363 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
6364 YYSIZE_T, not size_t.
6365 * tests/regression.at (Trivial grammars): New test, to catch
6366 the error fixed by the above patch.
6368 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6370 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
6372 Reported by Steve Murphy.
6374 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6376 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
6377 * data/glr.cc: b4_location_flag is now b4_locations_flag.
6379 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6381 Implement --trace=m4.
6382 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
6383 * src/output.c (output_skeleton): When set, pass -dV to m4.
6385 Factor the handling of flags in m4.
6386 * src/output.c (prepare): Rename the muscle names debug, defines,
6387 error_verbose to debug_flag, defines_flag, error_verbose_flag.
6388 * data/c.m4: Adjust.
6389 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
6390 Use b4_define_flag_if to define other b4_FLAG_if macros.
6391 (b4_location_if): As a consequence, rename as...
6392 (b4_locations_if): this, for consistency.
6393 Adjust all the skeletons.
6395 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6397 * etc/bench.pm: Shorten bench names.
6399 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6401 * src/output.h, src/output.c (error_verbose): Move to...
6402 * src/getargs.h, src/getargs.c: here.
6404 Adjust dependencies.
6406 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
6408 * data/c.m4 (b4_copyright): Put the special exception for Bison
6409 skeletons here, so we don't have to put it in each skeleton. All
6410 uses changed. Suggested by Akim Demaille. Also, wrap the
6411 copyright notice, in case it is longer than 80 columns. Replace
6412 comma by newline after title.
6414 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
6416 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
6417 incompatibility, not a bug. Mention that it wasn't fixed as of
6420 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
6422 * examples/extexi: Enforce the precedence of concatenation over
6424 Reported by Tommy Nordgren.
6426 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
6428 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
6429 with the member "token".
6430 Reported by Martin Nylin.
6432 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
6434 * data/glr.c: Switch to Bison 2.2 special-exception language in
6435 the copyright notice. Use more-regular format for titles and
6437 * data/glr.cc: Likewise.
6438 * data/location.cc: Likewise.
6439 * data/yacc.cc: Likewise.

6445 * data/glr.cc: Remove dead code.
6447 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
6449 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
6450 that variable and the line breaks the bootstrap. Problem reported
6451 by Juan M. Guerrero.
6453 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
6455 * doc/bison.texinfo (Multiple start-symbols): New.
6457 2006-04-24 Akim Demaille <akim@lrde.epita.fr>
6459 * etc/README, etc/bench.pl: New.
6461 2006-04-03 Akim Demaille <akim@lrde.epita.fr>

6465 Reported by Mickael Labau.
6466 * tests/input.at (Torturing the Scanner): Test it.
6468 2006-03-16 Paul Eggert <eggert@cs.ucla.edu>
6470 * doc/bison.texinfo (Decl Summary): Don't mention yylloc twice.
6471 Problem reported by Bob Rossi.
6473 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
6475 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
6476 and didn't really work.
6477 For the index, use @ifnotinfo, not @iftex.
6478 Minor cleanups of spacing and terminology.
6480 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
6482 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
6483 of AT_NAME_PREFIX when %name-prefix is not used.
6485 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
6487 Apply --prefix to C++ skeletons too: they change the namespace.
6488 The test suite already exercize these cases.
6489 * data/c++.m4 (b4_namespace): New.
6490 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
6491 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
6492 * data/yacc.c, data/glr.c: Remove a useless `[]'.
6493 * doc/bison.texinfo: Document it.
6494 (Option Cross Key): Use @multitable in all formats. It looks
6495 nicer, even in TeX outputs.
6496 (Rules): Use the same code whatever the output type is.
6497 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
6498 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
6499 * tests/calc.at: Use it, instead of hard coding `yy'.

6528 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
6530 Fix some nits reported by twlevo.
6531 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
6532 and "POSIX". Use more-modern syntax for URLs. Mention C++
6533 and ask for Java. Don't hardwire OS version numbers. Add
6535 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
6536 * src/conflicts.c (solved_conflicts_obstack): Now static.
6538 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
6540 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
6541 page. Say "you can use it" not "you may use it" as on the web page;
6542 we're describing capabilities not granting permission.
6544 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
6546 * data/glr.c (yyresolveLocations): Rename local variables to avoid
6547 shadowing warnings. Use usual patter for iterating through RHS.
6548 * tests/glr-regression.at
6549 (Uninitialized location when reporting ambiguity):
6550 Modify yylex so that it uses its argument, rather than trying
6551 to rely on ARGSUSED (which doesn't work for gcc with warnings).
6552 const char -> char const.
6554 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
6555 Don't use tabs inside commands; it messes up 'ps'.
6556 Problem reported by twlevo.
6558 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
6560 * tests/glr-regression.at (Uninitialized location when reporting
6561 ambiguity): New test case.
6562 * data/glr.c (yyresolveLocations): New function, which uses
6564 (yyresolveValue): Invoke yyresolveLocations before reporting an
6566 * doc/bison.texinfo (Default Action for Locations): Note
6567 YYLLOC_DEFAULT's usage for ambiguity locations.
6568 (GLR Semantic Actions): Cross-reference those notes.
6570 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
6572 * tests/glr-regression.at (Leaked semantic values when reporting
6573 ambiguity): Remove unnecessary union and type declarations.
6574 (Leaked lookahead after nondeterministic parse syntax error): New test
6576 * data/glr.c (yyparse): Check for zero stacks remaining before
6577 attempting to shift the lookahead so that you don't lose it.
6579 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
6581 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
6582 * tests/glr-regression.at (Leaked semantic values when reporting
6583 ambiguity): New test case.
6584 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
6585 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
6586 now unnecessary yystackp parameter.
6587 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
6588 destructors can be called.
6590 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
6591 in existing testcases.

6595 Don't leak semantic values for parent RHS when a user action cuts the
6596 parser, and clean up related code a bit.
6597 * tests/glr-regression.at (Leaked merged semantic value if user action
6598 cuts parse): Rename to...
6599 (Leaked semantic values if user action cuts parse): ... this. Add check
6600 for leaked parent RHS values.
6601 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
6602 between an unresolved state (non-empty chain of semantic options) and
6603 an incomplete one (signaled by an empty chain).
6604 (yyresolveStates): Document the interface. Move all manipulation of a
6605 successfully or unsuccessfully resolved yyGLRState to...
6606 (yyresolveValue): ... here so that yyresolveValue always leaves a
6607 yyGLRState with consistent data and thus is easier to understand.
6608 Remove the yyvalp and yylocp parameters since they are always just
6609 taken from the yys parameter. When reporting a discarded merged value
6610 in debugging output, note that it is incompletely merged. Document the
6612 (yyresolveAction): If resolving any of the RHS states fails, destroy
6613 them all rather than leaking them. Thus, as long as user actions are
6614 written to clean up the RHS correctly, yyresolveAction always cleans up
6615 the RHS of a semantic option. Document the interface.

6681 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
6682 nodist_PROGRAMS, since we don't need to actually compile the
6683 example if we're just doing a plain 'make'. This avoids bothering
6684 the installer unnecessarily about problems due to weird C++

6693 not portable, according to Posix and the C standard, and it does
6694 not work with Sun C 5.7, where previous #line directives affect

6734 During deterministic GLR operation, user actions should be able to
6735 influence the parse by changing yychar. To make this easier to fix and
6736 to make glr.c easier to evolve in general, don't maintain yytoken in
6737 parallel with yychar; just compute yytoken when needed.

6764 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
6765 got from <http://bro-ids.org/download.html>. The bug is that
6766 when two actions appeared in succession, the second one was
6767 scanned before the first one was added to the grammar rule
6768 as a midrule action. Bison then output the incorrect warning
6769 "parse.y:905.17-906.36: warning: unused value: $3".

7028 (Actions): Mention look-ahead usage of yylval.
7029 (Actions and Locations): Mention look-ahead usage of yylloc.
7030 (Special Features for Use in Actions): Add YYEOF entry and mention it
7031 in the yychar entry.
7032 In the yychar entry, remove mention of the local yychar case (pure
7033 parser) since this is irrelevant information when writing semantic
7034 actions and since it's already discussed in `Table of Symbols' where
7035 yychar is otherwise described as an external variable.
7036 In the yychar entry, don't call it the `current' look-ahead since it
7037 isn't when semantic actions are deferred.
7038 In the yychar and yyclearin entries, add note about deferred semantic
7040 Add yylloc and yylval entries discussing look-ahead usage.
7041 (Look-Ahead Tokens): When discussing yychar, don't call it the
7042 `current' look-ahead, and do mention yylval and yylloc.
7043 (Error Recovery): Cross-reference `Action Features' when mentioning
7045 (Table of Symbols): In the yychar entry, don't call it the `current'
7047 In the yylloc and yylval entries, mention look-ahead usage.

7055 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to
7056 use during nondeterministic operation to track which stacks have
7057 actually needed the current lookahead.
7058 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack):
7059 Allocate, deallocate, resize, and otherwise shuffle space for
7060 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
7061 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
7062 appropriately during nondeterministic operation.
7063 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
7064 members to store the current lookahead to be used by the deferred
7066 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
7067 from which the RHS is taken. Set the lookahead members of the new

7096 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
7098 * data/glr.c (yyresolveValue): When merging semantic options, if at
7099 least one user action succeeds but a later one cuts the parse, then
7100 destroy the semantic value before returning rather than leaking it.
7101 (yyresolveStates): If a user action cuts the parse and thus
7102 yyresolveValue fails, ignore the (unset) semantic value rather than
7103 corrupting the yyGLRState, and empty the semantic options list since
7104 the user actions should have called all necessary destructors.
7105 Simplify code with YYCHK.
7106 * tests/glr-regression.at (Corrupted semantic options if user action
7107 cuts parse): New test case.
7108 (Undesirable destructors if user action cuts parse): New test case.
7109 Before applying any of this patch, this test case never actually failed
7110 for me... but only because the corrupted semantic options usually

7355 destroy the RHS symbols of a rule.
7356 * data/yacc.c (yylen): Initialize to 0.

7373 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
7374 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.

7376 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with

7406 sed out the final state number.
7408 Work around portability problem on Solaris 10: flex-generated
7409 files include <stdio.h> before <config.h>, which messes up
7410 because the latter defines __EXTENSIONS__. Address the problem
7411 by creating two new little files that include <config.h> first,
7412 then include the flex-generated files. Rewrite everyone else
7413 to include <config.h> first, as well.
7414 * lib/timevar.c: Always include "config.h".

7462 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
7464 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
7465 * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
7466 Use YYID(0) rather than 0, for lint.
7467 (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.

7753 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
7755 Undo the parts of the unlocked-I/O change that substituted
7756 putc or puts for printf. This might hurt performance a bit,
7757 but some people prefer the printf style.

7788 Use unlocked I/O for a minor performance improvement on hosts like
7789 GNU/Linux and Solaris that support unlocked I/O. The basic idea
7790 is to use the gnlib unlocked-io module, and to prefer putc and

7969 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
7970 doesn't affect behavior.
7971 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
7973 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
7974 This works a bit better with glibc, if user code has already included
7976 * doc/bison.texinfo (Bison Parser): Document that users can't
7977 arbitrarily use malloc and free for other purposes. Document
7978 that <alloca.h> and <malloc.h> might be included.
7979 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
7980 user must declare alloca.
7982 * HACKING (release): Forwarn the Translation Project about
7985 2005-09-20 Akim Demaille <akim@epita.fr>
7987 * data/glr.c: Use b4_token_enums, not b4_token_enums_defines.
7989 2005-09-19 Paul Eggert <eggert@cs.ucla.edu>
7991 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
7992 (YYSTACK_ALLOC_MAXIMUM): Use it.
7993 (yysyntax_error): New function.
7994 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
7995 multiple syntax errors are reported, and alloca is being used.
7996 Instead, reallocate buffers twice as big each time, so that
7997 we waste at most half the allocated memory. Start with a small
7998 (128-byte) buffer that will suffice in most cases anyway.
7999 Use yysyntax_error to do most of the work.
8001 * doc/bison.texinfo (Error Reporting, Table of Symbols):
8002 yynerrs is the number of errors reported, not the number of
8005 * tests/glr-regression.at (Duplicated user destructor for lookahead):
8006 Mark it as expected to fail.
8007 Cast result of malloc; problem reported by twlevo@xs4all.nl.
8008 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
8009 Don't start user-code symbols with "yy", to avoid name space problems.
8011 2005-09-19 Akim Demaille <akim@epita.fr>
8013 Remove the traits, failed experiment.
8014 It never proved useful, and anyway because of the current
8015 definition, it was not possible to have several specialization of
8016 this traits, making it useless.
8017 * data/lalr1.cc (yy:traits): Remove.
8018 Inline its definitions in the parser class.
8020 2005-09-19 Akim Demaille <akim@epita.fr>

8023 least Mac OSX with a /usr/local install of gettext.
8025 2005-09-19 Akim Demaille <akim@epita.fr>
8027 * data/lalr1.cc (yyparse): Rename yylooka and yyilooka as yychar
8028 and yytoken for similarity with the other skeletons.
8030 2005-09-19 Akim Demaille <akim@epita.fr>

8042 * src/output.c (prepare): Likewise.
8043 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
8044 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
8045 is not defined. This is an awful hack, but it's enough for now.
8046 All callers changed.
8047 * tests/glr-regression-at (make_value): Args are const pointers now,
8048 to avoid GCC warning.
8049 (Duplicated user destructor for lookahead): New test. Currently
8050 skipped. It fails on my host but I'm not sure it'll always fail.
8052 2005-09-16 Akim Demaille <akim@epita.fr>
8054 * src/symtab.h (struct symbol): Declare the printer and destructor
8055 as const, to avoid accidental calls to free.
8056 (symbol_destructor_set, symbol_printer_set): Adjust.
8057 * src/symtab.c: Adjust.
8059 2005-09-16 Akim Demaille <akim@epita.fr>
8061 * data/c.m4 (b4_token_enums): New.
8062 (b4_token_defines): Rename as...
8063 (b4_token_enums_defines): this.
8064 (b4_token_defines): New, output only the #defines.
8065 * data/yacc.c, data/glr.c: Adjust.
8066 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
8067 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
8070 2005-09-16 Akim Demaille <akim@epita.fr>
8072 * data/lalr1.cc (yylex_): Remove, inline its code.
8073 (yyreport_syntax_error_): Remove, replaced by...
8074 (yysyntax_error_): this which returns a string and leaves to the
8075 caller the call to the users' error function.
8076 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
8077 Move from members of the parser object...
8078 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
8079 to local variables of the parse function.
8081 2005-09-16 Akim Demaille <akim@epita.fr>
8083 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
8084 since it's in Bison's name space.
8086 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
8088 * data/glr.c (yyresolveValue): Add default case to pacify
8089 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
8091 * NEWS: Document when yyparse started to return 2.
8092 * doc/bison.texinfo (Parser Function): Document when yyparse
8095 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
8096 (b4_filename_type): Renamed back from b4_file_name_type. All uses
8098 (class position): file_name -> filename (reverting). All uses changed.
8100 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
8102 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
8103 do anything if $@ exists. This reverts part of the 2005-07-07
8106 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
8108 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
8109 contains obsolete information and isn't worth distributing as a
8110 separate file anyway.
8111 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
8112 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
8113 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
8114 (yyparse): Abort if user code uses longjmp to throw an unexpected
8117 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
8119 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
8120 Suggested by twlevo@xs4all.nl.
8122 * data/glr.c (YYCHK1): Do not assume YYE is in range.
8123 This avoids a diagnostic from gcc -Wswitch-enum.
8124 Problem reported by twlevo@xs4all.nl.
8126 * doc/bison.texinfo: Don't use "filename", as per GNU coding
8127 standards. Use "file name" or "file" or "name", depending on
8129 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
8130 not to hack/foo.tab.c.
8131 (Calc++ Top Level): 2nd arg of main is not const.
8132 * data/glr.c: b4_filename -> b4_file_name.
8133 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.
8135 (class position): filename -> file_name. All uses changed.

8146 * lib/.cvsignore: Add pipe-safer.c, stdio--.h, unistd--.h,
8147 to accommodate latest gnulib.
8149 * tests/glr-regression.at (Duplicate representation of merged trees):
8150 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
8152 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
8155 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
8157 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
8158 All uses changed. Invoke user destructor after an error during a
8159 split parse (trivial change from Joel E. Denny).
8161 * tests/glr-regression.at
8162 (User destructor after an error during a split parse): New test case.
8163 Problem reported by Joel E. Denny in:
8164 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
8166 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
8168 * README-cvs: Give URLs for recommended tools.
8169 Mention Gzip version problem, and bootstrapping issues.
8170 Remove troubleshooting section, as it's somewhat obsolete.
8172 * bootstrap (no_cache): New var, to accommodate different wget
8173 variants. Use it instead of '-C off'. Problem reported by
8176 * data/glr.c (yydestroyStackItem): New function.
8177 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
8178 debugging information. Problem reported by Joel E. Denny.
8180 2005-08-25 Akim Demaille <akim@epita.fr>
8182 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
8184 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>

8188 * tests/glr-regression.at
8189 (User destructor for unresolved GLR semantic value): New test case.
8190 Problem reported by Joel E. Denny in:
8191 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
8193 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
8195 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
8197 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
8198 lib-prefix.m4, po.m4.
8200 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
8201 in yydestruct diagnostic, since it might not be an error.
8202 Problem reported by Joel Denny near end of
8203 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
8204 * data/lalr1.cc (yyerturn): Likewise.
8205 * data/yacc.c (yyreturn): Likewise.
8206 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
8208 * src/files.c: Remove obsolete FIXME comment.
8210 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
8211 with the other templates, and to fix bogus run-on messages such
8212 as the one reported at the end of
8213 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
8214 All callers changed to avoid the newline.
8215 (yyprocessOneStack): Output two lines rather than one, to accommodate
8216 the above change. This changes the debug output format slightly.
8218 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
8219 reported by Joel E. Denny in
8220 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
8222 * tests/glr-regression.at (Duplicate representation of merged trees):
8223 New test, from Joel E. Denny in:
8224 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
8225 * THANKS: Add Joel E. Denny.
8227 * configure.ac (AC_INIT): Bump to 2.0c.
8229 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
8231 * NEWS: Version 2.0b.
8233 * Makefile.am (SUBDIRS): Put examples before tests, so that
8234 "make check" doesn't finish with "All 1 tests passed".
8236 * tests/regression.at (Token definitions): Don't rely on
8237 AT_PARSER_CHECK for data that contains backslashes. It currently
8238 uses 'echo', and 'echo' isn't portable if its argument contains
8239 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
8240 that the byte '\0xff' is not printable in the C locale; it is,
8241 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
8242 not printable, so use '\0x81' to test.
8244 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
8245 version of GCC, since the macro is used with non-GCC compilers.
8247 Fix core dump reported by Pablo De Napoli in
8248 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
8249 * tests/regression.at (Invalid inputs with {}): New test.
8250 * src/parse-gram.y (token_name): Translate type before using
8253 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
8254 the user's name space. All uses changed to __attribute__
8256 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
8257 Add __attribute__ ((__noreturn__)).
8259 * etc/clcommit: Remove. We weren't using it, and it failed
8260 "make maintainer-distcheck".
8261 * Makefile.maint: Merge from coreutils.
8262 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
8263 (syntax-check-rules): Change list of rules as described below.
8264 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
8265 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):

8271 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
8272 (makefile-check, po-check, author_mark_check):
8273 (makefile_path_separator_check, copyright-check):
8274 Use grep -n, to make it easier to find violations.
8275 Use CVS_LIST and CVS_LIST_EXCEPT.
8276 (header_regexp, h_re): Remove.
8278 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
8279 (my-distcheck): Use more-modern GCC flags.
8280 (signatures, %.asc): Remove.
8281 (rel-files, announcement): Remove signatures.
8282 Restore old updating code, even though we don't use it, so
8283 that we're the same as coreutils.
8284 (alpha, beta, major): Depend on news-date-check.
8285 Make the upload commands.
8287 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
8288 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
8289 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
8290 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.

8294 * tests/sets.at: Likewise.
8296 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
8297 we comment out the Autoconf version number.
8298 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
8299 it's error-prone and "make maintainer-distcheck" rejects it.
8301 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
8302 Indent calls to "error" to pacify "make maintainer-distcheck",
8303 when the calls are not intended to be translated.
8304 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
8306 * src/Makefile.am (DEFS): Use +=, to pacify
8307 "make maintainer-distcheck".
8308 (bison_SOURCES): Add scan-skel.h.
8309 (sc_tight_scope): New rule, from coreutils.
8311 * src/files.c (src_extension, header_extension):
8312 Now static, not extern.
8313 * src/getargs.c (short_options): Likewise.
8314 * src/muscle_tab.c (muscle_table): Likewise.
8315 * src/parse-gram.y (current_class, current_type, current_prec):
8317 * src/reader.c (grammar_end, previous_rule_end): Likewise.
8318 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
8319 * src/main.c (main): Cast bindtextdomain and textdomain calls to
8320 void, to avoid warning when NLS is disabled.
8321 * src/output.c: Include scan-skel.h.
8322 (scan_skel): Remove decl, since scan-skel.h does this.
8324 Indent calls to "error" to pacify "make maintainer-distcheck".
8325 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
8326 * src/reader.h (gram_end, gram_lineno): New decls to pacify
8327 "make maintainer-distcheck".
8328 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
8329 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
8330 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
8331 (skel_lex_destroy, scan_skel): Move these decls to...
8332 * src/scan-skel.h: New file.
8333 * src/uniqstr.c (uniqstr_assert):
8334 Indent calls to "error" to pacify "make maintainer-distcheck".
8336 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
8339 * tests/torture.at: Revamp to avoid misuse of atoi that
8340 "make maintainer-distcheck" complained about.
8342 * examples/extexi (message): Don't print a message more than once,
8343 and omit line-number decoration that makes Emacs compile think
8344 that informative messages are worth worrying about.
8346 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
8348 * configure.ac: Update version number.
8350 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
8352 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
8353 autogenerated by the maintainer.
8354 * examples/calc++/.cvsignore: Add *.yy.
8356 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
8357 * lib/bitset_stats.c (bitset_stats_init): Likewise.
8358 * lib/bitsetv.c (bitsetv_alloc): Likewise.
8360 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
8362 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
8363 from maintainer-distcheck about casting the argument of 'free'.
8365 * NEWS: Mention recent yytname changes.
8366 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
8368 * bootstrap: For translations that have not yet been upgraded to
8369 the new runtime-po domain, prime the pump by extracting the
8370 relevant strings from the obsolete translations. This code can be
8371 removed once the bison-runtime domain has been translated by each
8374 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
8375 now that token names are already quoted.
8377 Fix problem reported by Anthony Heading.
8378 * data/glr.c (YYTOKEN_TABLE): New macro.
8379 (yytname): Define if YYTOKEN_TABLE.
8380 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
8381 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
8382 (YYERROR_VERBOSE): Define the same way the other skeletons do.
8383 * src/output.c (prepare_symbols): Output token_table_flag.
8385 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
8387 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
8388 again if the first call fails.
8390 * data/glr.c (yytnamerr): New function.
8391 (yyreportSyntaxError): Use it to dequote most string literals.
8392 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
8393 with other skeletons. All uses changed.
8394 (yytnameerr_): New function.
8395 (yyreport_syntax_error): Use it to dequote most string literals.
8396 * data/yacc.c (yytnamerr): New function.
8397 (yyerrlab): Use it to decode most string literals.
8398 * doc/bison.texinfo (Decl Summary, Calling Convention):
8399 Clarify quoting convention of yytname.
8400 * src/output.c (prepare_symbols): Quote all names. This undoes
8401 the 2005-04-17 change, which is now accomplished (mostly) via
8402 changes in the parsers as described above.
8403 * tests/regression.at (Token definitions, Web2c Actions):
8404 Undo most 2005-04-17 change here, too.
8406 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
8408 Fix more problems reported by twlevo@xs4all.nl.
8409 * tests/cxx-type.at: Don't pipe output of ./types through sed to
8410 remove trailing spaces. This loses the exit status of ./types,
8411 and isn't needed since ./types shouldn't be emitting trailing
8413 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
8414 as the stack isn't valid in that case.
8416 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
8417 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
8418 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
8419 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
8421 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
8422 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
8423 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
8426 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
8427 overly-picky compilers that reject 'char *foo = "bar";'.
8429 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
8430 to FILE * parameter, not to stderr. This fixes a typo introduced
8431 in the 2005-07-12 change.
8433 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
8434 warnings from GCC 4.
8436 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
8437 (yyglrShiftDefer, yysplitStack):
8438 Remove unused parameters b4_pure_formals. All uses changed.
8439 (yyglrShift): Remove unused parameters b4_user_formals.
8441 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
8443 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
8445 Destructor cleanups and regularization among the three skeletons.
8446 * NEWS: Document the behavior changes.
8447 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
8448 stack before failing, as the cleanup code will do it for us now.
8449 * data/lalr1.cc (yyerrlab): Likewise.
8450 * data/glr.c (yyparse): Pop everything off the stack before
8451 freeing it, so that destructors get called properly.
8452 * data/lalr1.cc (yyreturn): Likewise.
8453 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
8454 This is more consistent.
8455 * doc/bison.texinfo (Destructor Decl): Mention more reasons
8456 why destructors might be called. 1.875 -> 2.1.
8457 (Destructor Decl, Decl Summary, Table of Symbols):
8458 Some English-language cleanups for %destructor.
8459 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
8460 Add output line for destructor of start symbol.
8461 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
8462 because of that same extra output line.
8464 * NEWS: Document minor wording changes in diagnostics of
8465 Bison-generated parsers.
8466 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
8467 Remove unused formals. All uses changed.
8468 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
8469 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
8470 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
8471 Rename yyoverflowab to yyexhaustedlab.
8472 When memory exhaustion occurs during syntax-error reporting,
8473 report it separately rather than in a single diagnostic; this
8475 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
8476 (Memory Exhausted): Renamed from Parser Stack Overflow.
8477 Revamp wording slightly to prefer "memory exhaustion".
8478 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
8480 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
8482 Add i18n support to the GLR skeleton. Partially fix the C++
8483 skeleton; a C++ expert needs to finish this. Remove debugging
8484 msgids; there's little point to having them translated, since they
8485 can be understood only by someone who can read the
8486 (English-language) source code.
8488 Generate runtime-po/bison-runtime.pot automatically, so that we
8489 don't have to worry about garbage getting in that file. We'll
8490 make sure after the next official release that old msgids don't
8492 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
8494 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
8496 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
8497 Fix typos in explanations of the runtime file.
8498 * bootstrap: Change gettext keyword from YYI18N to YY_.
8499 Use standard Makefile.in.in in runtime-po, since we'll arrange
8500 for backward-compatible bison-runtime.po files in a different way.
8501 * data/glr.c (YY_): New macro, from yacc.c.
8502 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
8503 Translate messages intended for users.
8504 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
8505 the wording in the other skeletons. We don't know that the memory
8507 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
8508 Use same method that yacc.c uses.
8509 Don't translate debugging messages.
8510 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
8511 it doesn't work (yet), and requires C++ expertise to fix.
8512 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
8513 Move defn to a more logical place, to be consistent with other
8515 Don't translate debugging messages.
8516 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
8517 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
8518 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
8519 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
8521 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
8522 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
8524 * tests/glr-regression.at (Badly Collapsed GLR States):
8526 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
8527 yylex should return 0 at EOF rather than aborting.
8529 Improve tests for stack overflow in GLR parser.
8530 Problem reported by twlevo@xs4all.nl.
8531 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
8533 (yyStackOverflow): Just longjmp, but with value 2 so that caller
8534 can handle the problem.
8535 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
8536 (yyparse): New local variable yyresult to record the result.
8537 Use result of setjmp to set it, rather than storing itinto
8539 (yyDone): Remove label.
8540 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
8541 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
8542 if YYABORT is used).
8543 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
8544 yyparse status; put status > 1 into diagnostic.
8545 Check that status==2 works.
8546 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
8547 Use exit status 3 for failure to open (which shouldn't happen).
8549 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
8551 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
8552 1 on syntax error; just let yyparse do its thing.
8553 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
8554 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
8555 (Exploding the Stack Size with Alloca):
8556 (Exploding the Stack Size with Malloc):
8557 Expect exit status 2, not 1, since the parser is supposed to blow
8558 its stack. Problem reported by twlevo@xs4all.nl.
8560 * data/glr.c (yyparse): Don't assume that the initial calls
8561 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
8562 Print a stack-overflow message and fail instead.
8563 Initialize the line-number information before creating the stack,
8564 so that the stack-overflow message can report line zero safely.
8566 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
8568 Fix problems reported by twlevo@xs4all.nl.
8569 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
8570 (yyuserMerge): Provide a default case if b4_mergers is empty.
8571 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
8572 * tests/glr-regression.at
8573 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
8574 Add casts to pacify C++ compilers.
8575 * tests/glr-regression.at (Improper merging of GLR delayed action
8576 sets): Declare yylex before using it.
8577 * tests/Makefile.am (maintainer-check-g++): Fix a stray
8578 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
8579 test for valgrind; valgrind is independent of g++.
8580 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
8581 for compatibility with POSIX 1003.1-2001 (if running coreutils).
8582 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
8583 Use a destructor, so that we can expand the stack. Change
8584 YYSTYPE to char * so that we can free it. Cast result of malloc.
8586 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
8588 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
8589 a valgrind failure. Problem reported by twlevo@xs4all.nl.
8591 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
8593 * PACKAGING: New file, suggested by Bruno Haible and taken from
8594 similar wording in gettext's PACKAGING file.
8595 * NEWS: Mention PACKAGING.
8596 * Makefile.am (EXTRA_DIST): Add PACKAGING.
8598 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
8600 * NEWS: Document recent i18n improvements.
8601 * bootstrap: Get runtime translations into runtime-po.
8602 Create runtime-po files automatically, if possible.
8603 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
8604 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
8605 does not infringe on the user's name space.
8606 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
8607 * doc/bison.texinfo (Internationalization): Revamp the English
8608 and Texinfo syntax a bit, to try to make it clearer.
8609 (Bison Options, Option Cross Key): Mention --print-localedir.
8610 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
8611 YYENABLE_NLS. Quote a bit more.
8612 * runtime-po/.cvsignore: New file.
8613 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
8614 * runtime-po/Rules-quot: Remove; now created by bootstrap.
8615 * runtime-po/quot.sed: Likewise.
8616 * runtime-po/boldquot.sed: Likewise.
8617 * runtime-po/en@quot.header: Likewise.
8618 * runtime-po/en@boldquot.header: Likewise.
8619 * runtime-po/insert-header.sin: Likewise.
8620 * runtime-po/remove-potcdate.sin: Likewise.
8621 * runtime-po/Makevars: Likewise.
8622 * runtime-po/LINGUAS: Likewise.
8623 * runtime-po/de.po: Likewise; we will rely on the translation project
8624 to maintain this, so "bootstrap" should get it.
8625 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
8627 * src/main.c (main): Bind the bison-runtime domain, too.
8629 2005-07-12 Bruno Haible <bruno@clisp.org>
8631 * data/yacc.c: Include <libintl.h> when NLS is enabled.
8632 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
8633 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
8634 * runtime-po: New directory.
8635 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
8636 $(DOMAIN).pot-update rule, so that old messages are never dropped.
8637 * runtime-po/Rules-quot: New file, copied from po/.
8638 * runtime-po/quot.sed: Likewise.
8639 * runtime-po/boldquot.sed: Likewise.
8640 * runtime-po/en@quot.header: Likewise.
8641 * runtime-po/en@boldquot.header: Likewise.
8642 * runtime-po/insert-header.sin: Likewise.
8643 * runtime-po/remove-potcdate.sin: Likewise.
8644 * runtime-po/Makevars: New file.
8645 * runtime-po/POTFILES.in: New file.
8646 * runtime-po/LINGUAS: New file.
8647 * runtime-po/bison-runtime.pot: New file.
8648 * runtime-po/de.po: New file.
8649 * m4/bison.m4: New file.
8650 * Makefile.am (SUBDIRS): Add runtime-po.
8651 (aclocaldir, aclocal_DATA): New variables.
8652 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
8654 * src/getargs.c (usage): Document --print-localedir option.
8655 (PRINT_LOCALEDIR_OPTION): New enum item.
8656 (long_options): Add --print-localedir option.
8657 (getargs): Handle --print-localedir option.
8658 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
8659 (Internationalization): New section.
8661 2005-07-12 Akim Demaille <akim@epita.fr>
8663 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
8664 for consistency with the rest of the code.
8665 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
8668 2005-07-12 Akim Demaille <akim@epita.fr>
8670 * src/parse-gram.y: Use %printer instead of YYPRINT.
8672 2005-07-12 Akim Demaille <akim@epita.fr>
8674 * src/symtab.h, src/symtab.c (symbol_print): New.
8675 * src/symlist.h, src/symlist.c (symbol_list_print): New.
8676 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
8678 2005-07-12 Akim Demaille <akim@epita.fr>
8680 * data/glr.c (b4_syncline): Fix (swap) the definitions of
8681 b4_at_dollar and b4_dollar_dollar.
8683 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
8685 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
8686 and Pennello's paper.
8688 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
8690 * data/yacc.c (yyparse): Undo previous patch. Instead,
8691 set yylsp[0] and yyvsp[0] only if the initial action
8692 sets yylloc and yylval, respectively.
8694 * data/yacc.c (yyparse): In the initial action, set
8695 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
8696 This avoids the use of undefined variables if the initial
8697 action does not set yylloc and/or yylval.
8699 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
8701 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
8702 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
8703 Remove from CVS. These files are automatically generated.
8704 * examples/extexi: Clarify that this file is now part of Bison,
8705 not GNU M4, and that it works with any POSIX-compatible Awk.
8706 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
8707 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
8708 so that we also get calc++-parser.yy. Geneate it.
8709 Use $(AWK), not gawk, since any conforming Awk will do.
8710 Put comment before action, since older 'make' can't handle comment
8712 $(BUILT_SOURCES): List all built sources, not just some of them.
8713 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
8714 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
8715 $($(calc_sources_generated)): Remove unnecessary test for existence
8716 of target. (This had a shell syntax error anyway; a stray "x".)
8717 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
8719 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
8721 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
8722 implied by the other modules.
8724 2005-07-06 Akim Demaille <akim@epita.fr>
8726 Bind examples/calc++ to the package.

8735 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
8737 * data/glr.c (yyFail): Drastically simplify; since the format argument
8738 never had any % directives, we can simply pass it to yyerror.
8739 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
8740 be modified later, as that is the usual style in glr.c.
8741 Problems reported by Paul Hilfinger.
8743 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
8744 and size overflow errors.
8745 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
8746 in case the user prolog sets feature-test macros like _GNU_SOURCE.
8747 (YYSIZEMAX): New macro.
8748 (yystpcpy): New function, taken from yacc.c.
8749 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
8750 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
8751 so that we don't have to maintain their signatures.
8752 (yyFail): Check for buffer overflow, by using vsnprintf rather
8753 than vsprintf. Allocate a bigger buffer if possible.
8754 Report an error if buffer allocation fails.
8755 (yyStackOverflow): New function.
8756 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
8757 the initialization was successful. It might fail if storage was
8759 (yyexpandGLRStack): Add more checks for storage allocation failure.
8760 Use yyStackOverflow to report failures.
8761 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
8762 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
8763 Don't assume stack number fits in int.
8764 (yysplitStack): Check for storage allocation failure.
8765 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
8766 can print diagnostics on storage allocation failure. All callers
8768 (yyresolveValue): Use yybool for boolean.
8769 (yyreportSyntaxError): Check for size-calculation overflow.
8770 This code is taken from yacc.c.
8771 (yyparse): Check for storage allocation errors when allocating
8774 2005-07-05 Akim Demaille <akim@epita.fr>
8776 Extract calc++ from the documentation.
8777 * doc/bison.texinfo (Calc++): Add the extraction marks.
8778 * examples/extexi: New, from the aborted GNU Programming 2E.
8779 Separate the different paragraph of a file with empty lines.
8780 * examples/Makefile: Use it to extract the whole calc++ example.
8782 2005-06-24 Akim Demaille <akim@epita.fr>
8784 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
8787 2005-06-22 Akim Demaille <akim@epita.fr>
8789 * doc/bison.texinfo (C++ Language Interface): First stab.
8790 (C++ Parsers): Remove.
8792 2005-06-22 Akim Demaille <akim@epita.fr>
8794 * data/lalr1.cc (yylex_): Honor %lex-param.
8796 2005-06-22 Akim Demaille <akim@epita.fr>
8798 Start a set of simple examples.
8799 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
8800 * examples/calc++/calc++-driver.hh,
8801 * examples/calc++/calc++-parser.yy,
8802 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
8803 * examples/calc++/compile, examples/calc++/test: New.
8805 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
8807 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
8808 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
8809 which stems from the 2005-05-27 patch.
8811 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
8813 * data/glr.c: Modify treatment of unused parameters to permit use
8814 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
8816 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
8818 Fix infringement on user name space reported by Janos Zoltan Szabo.
8819 * data/yacc.c (yyparse): strlen -> yystrlen.
8821 2005-05-30 Akim Demaille <akim@epita.fr>
8823 * data/lalr1.cc (_): New.
8824 Translate the various messages.
8826 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
8828 Fix infringement on user name space reported by Bruno Haible.
8829 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
8830 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
8831 the user's name space.
8832 (alloca): Include <stdlib.h> to get it, if it's not built in.
8833 (YYMALLOC, YYFREE): Define only if needed.
8834 (malloc, free): Declare, but only if needed, as this infringes on
8835 the user name space.
8837 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
8839 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
8840 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
8842 * lib/ebitset.c (min, max): Undef before defining.
8843 * lib/vbitset.c (min, max): Likewise.
8844 * lib/subpipe.c (create_subpipe): Save local variables in case
8845 vfork clobbers them.
8847 2005-05-24 Bruno Haible <bruno@clisp.org>
8849 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
8850 error message syntax used by gcc-4.0.
8852 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
8854 * README: Mention m4 1.4.3. Remove obsolete advice about
8855 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
8857 * bootstrap: Remove workaround for problem I encountered with
8858 gettext 0.14.1; it seems to be fixed now.
8860 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
8862 * NEWS: Version 2.0a.
8864 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
8865 the previous change.
8867 Various maintainer cleanups.
8868 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
8869 conftest*, for benefit of CVS commands run at the same time as
8870 "configure". Add build-aux, since "bootstrap" now creates it and
8872 * Makefile.cfg (move_if_change): Remove.
8873 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
8874 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
8875 (po_repo, do-po-update, po-update, wget_files, get-targets):

8879 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
8881 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
8882 this is now the recommended name.
8883 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
8884 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
8885 ylwrap. These files now go into build-aux.
8886 * config/move-if-change: Remove.
8887 * config/prev-version.txt: Bump from 1.75 to 2.0.
8889 * bootstrap: Add stdio-safer, unistd-safer modules.
8890 Remove m4/glibc2.m4 (introduced by latest gnulib, but
8892 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
8893 fopen-safer.c, stdio-safer.h, unistd-safer.h.
8894 * lib/subpipe.c: Include "unistd-safer.h".
8895 (create_subpipe): Make sure all the newly-created
8896 file descriptors are > 2, so that diagnostics don't
8897 get sent down them (which might cause Bison to hang, in theory).
8898 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
8899 * src/files.c (xfopen): Use fopen_safer, not fopen.
8901 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
8902 yesterday's yacc.c fix.
8904 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
8906 * data/glr.c, data/lalr1.cc: Update copyright date.
8908 Fix a destructor bug reported by Wolfgang Spraul in
8909 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
8910 * data/yacc.c (yyabortlab): Don't call destructor, and
8911 don't set yychar to EMPTY.
8912 (yyoverflowlab): Don't call destructor.
8913 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
8914 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
8915 since we no longer output the message "discarding lookahead token
8918 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
8920 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
8921 fix a small glitch in debugging output.
8922 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
8923 after YY_SYMBOL_PRINT where needed.
8925 (struct yyGLRState): Add some comments.
8926 (struct yySemanticOption): Add some comments.
8927 (union yyGLRStackItem): Add comment.
8929 (yymergeOptionSets): Correct this to properly perform the union,
8930 avoiding infinite reported by Michael Rosien.
8933 * tests/glr-regression.at: Add test for GLR merging error reported

8974 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
8976 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
8977 Problem reported by Ralf Menzel.
8979 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8981 * tests/actions.at: Test that stack overflow invokes destructors.
8982 From Marcus Holland-Moritz.
8983 * data/yacc.c (yyerrlab): Move the code that destroys the stack
8985 (yyreturn): to here. That way, destructors are called properly
8986 even if the stack overflows, or the user calls YYACCEPT or
8987 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
8988 (yyoverflowlab): Destroy the lookahead.
8990 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
8992 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
8994 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
8996 * NEWS: Bison-generated C parsers no longer quote literal strings
8997 associated with tokens.
8998 * src/output.c (prepare_symbols): Don't escape strings,
8999 since users don't want to see C escapes.
9000 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
9002 * tests/input.at (Torturing the Scanner): Likewise.
9003 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
9005 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
9007 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
9008 the data size is known to be too small and we can't increase it.
9009 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
9011 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
9013 * src/parse-gram.y: Include quotearg.h.
9014 (string_as_id): Quote $1 before using it as a key, since the
9015 lexer no longer quotes it for us.
9016 (string_content): Don't strip quotes, since lexer no longer
9018 * src/scan-gram.l: Include quotearg.h.
9020 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
9021 a key, since the rest of the lexer doesn't quote it.
9022 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
9023 * tests/regression.at (Token definitions): Check for backslashes
9026 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
9027 (YYSIZE_T): Define to unsigned long int when using an older compiler.
9028 (yyparse): Revamp code to generate long syntax error message, to
9029 make it easier to translate, and to avoid problems with arithmetic
9030 overflow. Change "virtual memory" to "memory" in diagnostic, since
9031 we don't know whether the memory is virtual.
9033 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
9035 * NEWS: Bison-generated C parsers now use the _ macro to
9037 * data/yacc.c (_) [!defined _]: New macro.
9038 All English strings wrapped inside this macro.
9039 * doc/bison.texinfo (Bison Parser): Document _.
9040 * po/POTFILES.in: Include src/parse-gram.c, since it now
9041 includes translateable strings that parse-gram.y doesn't.
9043 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
9045 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
9046 reverting the 2004-10-11 change to this function.
9047 (symbol_check_alias_consistency): Don't call symbol_type_set
9048 if the type name is already correct.
9049 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
9051 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
9053 * tests/regression.at (Token definitions): Don't use a token named
9054 c, as that generates a "#define c ..." that runs afoul of buggy
9055 stdlib.h that uses the identifier c as a member of struct
9056 drand48_data. Problem reported by Horst Wente.
9058 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
9060 * bootstrap: Change translation URL from
9061 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
9062 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
9063 redirection glitches. Problem reported by twlevo@xs4all.nl.
9065 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
9067 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
9068 after operands; POSIX says this isn't portable for the c99 command.
9070 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
9072 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
9073 immediately if a data overrun has occurred; this may help us track
9074 down what may be a spurious failure on MacOS.
9076 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
9078 Respond to problems reported by twlevo@xs4all.nl.
9080 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
9082 * src/vcg.h: Comment fix.
9083 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
9084 (G_CMAX): Change to -1 instead of INT_MAX.
9086 * data/yacc.c (yyparse): Omit spaces before #line.
9088 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
9090 * src/tables.c (state_number_to_vector_number): Put it inside an
9091 "#if 0", since it's not currently used. Problem reported by
9094 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
9096 * src/output.c (escaped_output): Renamed from
9097 escaped_file_name_output, since we now use it for symbol tags as
9098 well. All uses changed.
9099 (symbol_destructors_output, symbol_printers_output):
9100 Escape symbol tags too.
9101 Problem reported by Matyas Forstner in
9102 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
9104 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
9106 * src/output.c (user_actions_output, token_definitions_output,
9107 symbol_destructors_output, symbol_printers_output): Likewise.
9108 * src/reader.c (prologue_augment): Likewise.
9109 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
9111 * src/vcg.c (output_edge): Don't quote linestyle arg.
9112 Problem reported by twlevo@xs4all.nl.
9114 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
9116 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
9117 example, reported by Derek M Jones. Also, make the example even
9118 more outrageous, to better illustrate how bad the problem is.
9120 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
9122 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
9123 putsym. Typo reported by Sebastian Piping.
9125 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
9127 * doc/bison.texinfo (Language and Grammar): some -> same
9128 (Epilogue): int he -> in the
9129 Typos reported by Sebastian Piping via Justin Pence.
9131 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
9133 * tests/glr-regression.at (Improper handling of embedded actions
9134 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
9135 embedded actions and $-N in GLR parsers", work around an Autoconf bug
9136 with dollar signs in test names.
9137 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
9138 for a similar reason.
9140 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
9142 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
9143 wants to redefine G_VIEW.
9145 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
9147 * src/vcg.c (get_view_str): Remove case for normal_view.
9148 Problem reported by twlevo@xs4all.nl.
9150 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
9152 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
9153 Problem reported by twlevo@xs4all.nl.
9155 * doc/bison.texinfo: Change @dircategory from "GNU programming
9156 tools" to "Software development". Requested by Richard Stallman
9159 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
9161 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
9162 Problem reported by twlevo@xs4all.nl.
9164 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
9166 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
9167 keyword; it's not needed with modern compilers, and it doesn't
9168 affect correctness with older compilers. Suggested by
9171 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
9173 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
9174 gcc -Wswitch-default.
9175 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
9176 * data/yacc.c (yyparse): Likewise.
9178 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
9180 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
9181 already. Let config.h define any nonstandard values.
9183 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
9185 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
9186 for the benefit of slower hosts. Problem reported by
9189 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
9191 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
9192 being defined and not used.
9193 * data/lalr1.cc (yyparse): Likewise.
9194 Use "if (false)" rather than "if (0)".
9196 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
9198 * TODO: Mention that we should allow NUL bytes in tokens.
9200 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
9202 * src/scan-skel.l (<<EOF>>): Don't close standard output.
9203 Problem reported by Hans Aberg.
9205 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
9207 * src/getargs.c (version): Happy new year; update overall
9208 program copyright date from 2004 to 2005.
9210 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
9211 Problem reported by Hans Aberg.
9212 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
9213 (Output file names.): Add a test for the case when standard output
9216 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
9218 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
9219 to fix an oversight in the Bison 2.0 manual.
9221 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
9223 * NEWS: Version 2.0. Reformat the existing news items since
9224 1.875, so that related items are grouped together.
9225 * configure.ac (AC_INIT): Bump version to 2.0.
9226 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
9228 * tests/torture.at (Exploding the Stack Size with Alloca): Set
9229 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
9230 otherwise, we're not testing alloca. Unfortunately there's no
9231 simple way to consult HAVE_ALLOCA here.
9233 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
9236 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
9237 hand. This avoids a warning about comparing int to size_t when
9238 GCC warnings are enabled.
9240 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
9242 * NEWS: Bison-generated parsers no longer default to using the
9243 alloca function (when available) to extend the parser stack, due
9244 to widespread problems in unchecked stack-overflow detection.
9245 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
9246 responsibility to set it to a positive value. This lets the user
9247 specify a value that is not a preprocessor constant.
9248 * data/yacc.c (YYMAXDEPTH): Likewise.
9249 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
9250 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
9251 to be a compile-time constant. However, explain the constraints on it.
9252 Also, explain the constraints on YYINITDEPTH.
9253 (Table of Symbols): Explain that alloca is no longer the default.
9254 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
9257 * doc/bison.texinfo (Location Default Action): Mention that n must
9258 be zero when k is zero. Suggested by Frank Heckenbach.
9260 2004-12-22 Akim Demaille <akim@epita.fr>
9262 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
9263 (parser::state_type, parser::semantic_type, parser::location_type):
9264 Private, not public.
9265 (parser::parse): Return ints, not bool.
9266 Returning a bool introduces a problem: 0 corresponds to false, and
9267 it seems weird to return false on success. Returning true changes
9268 the conventions for yyparse.
9269 Alternatively we could return void and send an exception.
9270 There is no clear consensus (yet?).
9271 (state_stack, semantic_stack, location_stack): Rename as...
9272 (state_stack_type, semantic_stack_type, location_stack_type): these.
9273 Private, not public.
9274 * tests/c++.at: New.
9275 * tests/testsuite.at, tests/Makefile.am: Adjust.
9277 2004-12-21 Akim Demaille <akim@epita.fr>
9279 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
9281 2004-12-21 Akim Demaille <akim@epita.fr>
9283 Don't impose std::string for filenames.
9285 * data/lalr1.cc (b4_filename_type): New.
9286 (position::filename): Use it.
9287 (parser.hh): Move the inclusion of stack.hh and location.hh below
9288 the user code, so that needed headers for the filename type can be
9290 Forward declare them before the user code.
9291 * tests/Makefile.am (check-local, installcheck-local): Pass
9292 TESTSUITEFLAGS to the TESTSUITE.
9294 2004-12-20 Akim Demaille <akim@epita.fr>
9296 Use more STL like names: my_class instead of MyClass.
9298 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
9299 (SemanticStack, SemanticType, StateStack, StateType)
9300 (TokenNumberType, Stack, Slice, Traits, Parser::location)
9301 (Parser::value): Rename as...
9302 (location_stack, location_type, rhs_number_type, semantic_stack)
9303 (semantic_type, state_stack, state_type, token_number_type, stack)
9304 (slice, traits, parser::yylloc, parser::yylval): these.
9306 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
9308 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
9310 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
9311 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
9313 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
9315 Remove uses of 'short int' and 'unsigned short int'. This raises
9316 some arbitrary limits. It uses more memory but nowadays that's
9317 not much of an issue.
9319 This change does not affect the generated parsers; that's a different
9320 task, as some users will want to conserve memory there.
9322 Ideally we should use size_t to represent all object counts, and
9323 something like ptrdiff_t to represent signed differences of object
9324 counts; but that will require more code-cleanup than I have the
9325 time to do right now.
9327 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
9328 Use size_t, not int or short int, to count objects.
9329 * src/closure.c (nritemset, closure): Likewise.
9330 * src/closure.h (nritemset, closure): Likewise.
9331 * src/nullable.c (nullable_compute): Likewise.
9332 * src/print.c (print_core): Likewise.

9348 2004-12-17 Akim Demaille <akim@epita.fr>
9350 * data/lalr1.cc: Extensive Doxygenation.
9351 (error_): Rename as...
9352 (error): this, since it is visible to the user.
9354 (Parser::message): Now an automatic variable from...
9355 (Parser::yyreport_syntax_error_): here.
9356 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
9358 * tests/input.at: Escape $.
9360 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
9362 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
9363 Parenthesize rhs to avoid obscure problems with mistakes like
9364 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
9365 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
9366 b4_rhs_location): Likewise.

9378 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
9381 2004-12-16 Akim Demaille <akim@epita.fr>
9383 Use #define to handle the %name-prefix.
9385 * data/glr.c, data/yacc.c: Comment changes.
9386 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
9387 so that one can refer to yylex in the parser file, and have it
9388 renamed, as is the case with other skeletons.
9390 2004-12-16 Akim Demaille <akim@epita.fr>

9412 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
9414 Fix some problems reported by twlevo at xs4all.
9415 * src/symtab.c (symbol_new): Report an error if the input grammar
9416 contains too many symbols. This is better than calling abort() later.
9417 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
9418 (struct node, struct graph):
9419 Rename member expand to stretch. All uses changed.
9420 (struct graph): Remove member layoutalgorithm. All uses removed.

9443 2004-12-15 Akim Demaille <akim@epita.fr>
9445 Simplify the C++ parser constructor.
9447 * data/lalr1.cc (debug_): Rename as...
9448 (yydebug_): so that the parser's internals are always in the yy*
9451 (b4_parse_param_decl): Remove the leading comma as it is now only
9452 called as unique argument list.
9453 (Parser::Parser): Remove the constructor accepting a location and
9454 an initial debugging level.
9455 Remove from the other ctor the argument for the debugging level.
9456 (debug_level_type, debug_level, set_debug_level): New.
9458 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
9461 2004-12-15 Akim Demaille <akim@epita.fr>
9463 Remove b4_root related material: failure experiment
9464 (which goal was to allow to derive from a class).
9466 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
9467 definitions and uses.
9469 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
9471 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
9472 not 2, since it's not portable to subtract 1 from the start of an
9473 array. The new item 0 is never set or used. All uses changed.
9475 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
9476 the default definition of YYLLOC_DEFAULT. Problem reported
9477 by Frank Heckenbach.
9479 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
9481 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
9482 the normal case and one for the error case. Just use the
9483 first one uniformly. Problem reported by Frank Heckenbach.
9484 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
9485 use exactly the same macro in both places.
9486 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
9487 so that the normal-case YYRHSLOC works for the error case too.
9489 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
9490 (YYLLOC_DEFAULT): Use the same macro as glr.c.
9491 * doc/bison.texinfo (Location Default Action): Don't claim that
9492 we have an array of locations. Use the same macro for both glr
9493 and lalr parsers. Mention YYRHSLOC. Mention what happens when
9496 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
9498 * HACKING: Update email addresses to send announcements to.
9500 * configure.ac (AC_INIT): Bump version to 1.875f.

9505 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
9507 * src/scan-skel.l: Include "complain.h", for "fatal".
9509 * src/relation.h (relation_print, relation_digraph):
9510 Relation sizes are of type relation_node, not size_t (this is
9511 merely a doc fix, since the two types are equivalent).
9512 (relation_transpose): Relation sizes are of type relation_node,
9514 * src/relation.c: Likewise.
9515 (top, infinity): Now of type relation_node, not int.

9518 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
9519 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
9520 (yyparse): Remove unused local introduced in 2004-10-25 patch.
9522 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
9523 specifying whether the test should be skipped. Use it tp
9524 specify that the [%defines %skeleton "lalr1.cc"] tests currently
9525 fail on some hosts, and should be skipped.
9527 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
9529 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
9530 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
9531 unless otherwise specified below.
9533 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
9534 to allocate kernel_base, kernel_items, kernel_size, since
9535 they needn't be initialized to 0.
9536 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
9537 * src/closure.c (new_closure): Likewise, for itemset.
9538 * src/derives.c (derives_compute): Likewise, for delts, derives, q.

9544 * src/reduce.c (nonterminals_reduce): Likewise for nontermmap.
9545 * src/relation.c (relation_digraph): Likewise for VERTICES.
9546 (relation_transpose): Likewise for new_R, end_R.
9547 * src/symtab.c (symbols_token_translations_init): Likewise for
9549 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.
9550 (token_actions): Likewise for yydefact, actrow, conflrow,
9552 (save_column): Likewise for froms[symno], tos[symno].
9553 (goto_actions): Likewise for state_count.
9554 (pack_table): Likewise for base, pos, check.
9555 (tables_generate): Likewise for width.
9557 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
9558 for initial core. Just have a separate core, so we needn't worry
9559 about whether kernel_size and kernel_base are initialized.
9561 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
9562 kernel_size, kernel_items): Remove unnecessary initialization.
9563 * src/conflicts.c (conflicts): Likewise.
9564 * src/derives.c (derives): Likewise.
9565 * src/muscle_tablc (muscle_insert): Likewise.

9567 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
9568 conflrow, conflict_table, conflict_list, table, check):
9571 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
9572 This is because all callers pass unsigned int.
9573 * src/closure.h (new_closure): Likewise.
9575 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
9576 (build_relations): Initialize includes[i] in all cases.
9577 * src/reader.c (packgram): Always initialize rules[ruleno].prec
9578 and rules[ruleno].precsym. Initialize members in order.
9579 * src/relation.c (relation_transpose): Always initialize new_R[i]
9581 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
9583 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
9584 conflict_list[0] was always 0, but now it isn't initialized.
9586 * src/table.c (table_grow): When conflict_table grew, the grown
9587 area wasn't cleared. Fix this.
9589 * lib/.cvsignore: Add strdup.c, strdup.h.
9590 * m4/.cvsignore: Add strdup.m4.
9592 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
9594 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
9595 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
9596 GOTO_NUMBER_MAXIMUM, since we occasionally compute
9597 ngotos + 1 without checking for overflow.
9598 (build_relations): Use END_NODE, not -1, to denote end of edges.
9599 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
9600 build_relations): Use goto_number, not int, for goto numbers.
9601 * src/tables.c (save_column, default_goto): Likewise.
9603 2004-11-23 Akim Demaille <akim@epita.fr>
9605 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
9606 of #defining from yystype.
9607 Don't typedef yystype, C++ does not need it.
9608 This lets it possible to forward declare it as union.
9610 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
9612 * bootstrap (gnulib_modules): Add extensions.
9613 Problem reported by Jim Meyering.
9615 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
9617 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
9618 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
9619 src/system.h, src/tables.c: XFREE -> free, to accommodate
9620 recent change to gnulib xalloc.h.
9621 Problem reported by Jim Meyering.
9623 2004-11-17 Akim Demaille <akim@epita.fr>
9625 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
9627 2004-11-17 Akim Demaille <akim@epita.fr>,
9628 Alexandre Duret-Lutz <adl@gnu.org>
9630 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
9633 Use it instead of cdebug_.
9634 (Parser::debug_stream, Parser::set_debug_stream): New.
9635 (Parser::symprint_): Define cdebug_ for temporary backward
9637 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
9640 2004-11-17 Akim Demaille <akim@epita.fr>
9642 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
9643 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
9644 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
9645 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.

9650 Problem reported by Frank Heckenbach.
9652 2004-10-25 Akim Demaille <akim@epita.fr>
9654 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
9655 Introduce another definition to address simple location arrays.
9656 (yyGLRStack): New member: yyerror_range.
9657 (yyrecoverSyntaxError, yyparse): Update it.
9658 (yyrecoverSyntaxError): Use it when shifting the error token to
9659 have an accurate range, equivalent to the one computed by both
9660 yacc.c and lalr1.cc.
9661 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
9662 that column numbers start at column 0, as per GNU Coding
9663 Standards, the others tests, and the doc.
9664 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
9665 Adjust to the above change (first column is 0).
9666 And adjust the location of the "<error>", now covering the whole
9669 2004-10-22 Akim Demaille <akim@epita.fr>
9670 and Paul Eggert <eggert@cs.ucla.edu>
9672 Remove some arbitrary limits on goto numbers and relations.
9673 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
9674 initial values, since they're never used.
9675 (set_goto_map): ngotos is now unsigned, so test for overflow
9676 by seeing whether it wraps around to zero.
9677 * src/lalr.h (goto_number): Now size_t, not short int.
9678 (GOTO_NUMBER_MAXIMUM): Remove.
9679 * src/relation.c (relation_print, traverse, relation_transpose):
9680 Check for END_NODE rather than looking at sign.
9681 * src/relation.h (END_NODE): New macro.
9682 (relation_node): Now size_t, not short int.
9684 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
9686 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
9687 keyword, not an identifier. Problem reported by Baron Schwartz in
9688 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
9690 2004-10-11 Akim Demaille <akim@epita.fr>
9692 * src/symtab.c (symbol_check_alias_consistency): Also check
9693 type names, destructors, and printers.
9694 Reported by Alexandre Duret-Lutz.
9695 Recode the handling of associativity and precedence in terms
9696 of symbol_precedence_set.
9697 Accept no redeclaration at all, not even equal to the previous
9699 (redeclaration): New.
9700 Use it to factor redeclaration complaints.
9701 (symbol_make_alias): Don't set the type of the alias, let
9702 symbol_check_alias_consistency do it as for other features.
9703 * src/symtab.h (symbol): Add new member prec_location, and
9705 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
9706 * tests/input.at (Incompatible Aliases): New.
9708 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
9710 .cvsignore fixes to accommodate gnulib changes,
9711 and the practice of naming build directories "_build".
9712 * .cvsignore: Add "_*". Sort.
9713 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
9714 * m4/.cvsignore: Add "*_gl.m4".
9716 2004-10-06 Akim Demaille <akim@epita.fr>
9718 * src/parse-gram.y (add_param): Fix the truncation of trailing
9721 2004-10-05 Akim Demaille <akim@epita.fr>
9723 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
9724 whether the reducion was empty or not. This leaves room to
9725 improve the use of YYLLOC_DEFAULT in such a case.
9726 lalr1.cc is still experimental, so changing this is acceptable.
9727 And finally, there are probably not many users who changed the
9728 handling of locations in GLR, so changing is admissible too.
9730 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
9731 empty reduction, set @$ to an empty location ending the previously
9733 Adjust uses to make sure the code is triggered on empty
9735 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
9736 expected output: empty reductions have empty locations.
9738 2004-09-29 Akim Demaille <akim@epita.fr>
9740 * data/lalr1.cc: Move towards a more standard C++ coding style
9741 for templates: Class < T > -> Class<T>.
9743 2004-09-29 Akim Demaille <akim@epita.fr>
9745 * data/lalr1.cc: Reinstall the former ctor, for sake of
9746 compatibility, but warn it will be removed.
9747 Move towards a more standard C++ coding style (i.e., type *var ->
9750 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
9752 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
9753 since it's less likely to work if NULs are involved in the future.
9755 2004-09-27 Akim Demaille <akim@epita.fr>
9757 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
9759 2004-09-27 Akim Demaille <akim@epita.fr>
9761 * data/lalr1.cc (b4_parse_param_decl_1): New.
9762 (b4_parse_param_decl): Use it to have different names between attribute

9766 2004-09-24 Akim Demaille <akim@epita.fr>
9768 * src/parse-gram.y (add_param): Strip the leading and trailing
9769 blanks from a formal argument declaration.
9770 (YY_LOCATION_PRINT): New.
9772 2004-09-24 Akim Demaille <akim@epita.fr>
9774 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
9777 2004-09-24 Akim Demaille <akim@epita.fr>
9779 * doc/bison.texinfo (Table of Symbols): Sort.
9781 2004-09-21 Akim Demaille <akim@epita.fr>
9783 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
9784 the useless parentheses.
9785 Suggested by Paul Eggert.
9787 2004-09-20 Akim Demaille <akim@epita.fr>
9789 Let the initial-action act on the look-ahead, and use it for the
9790 "initial push" (corresponding to an hypothetical beginning-of-file).
9791 And let lalr1.cc honor %initial-action.
9793 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
9795 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
9796 (Parser::Parser): Remove the ctor that used to initialize it.
9797 (Parser::parse): Like in the other skeletons, issue the "starting
9798 parse" message before any action.
9799 Honor %initial-action.
9800 Initialize the stacks with the lookahead.
9801 * data/yacc.c: Let $$ and @$ in %initial-action designate the
9803 Push them in the stacks.
9804 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
9806 2004-09-20 Akim Demaille <akim@epita.fr>
9808 * doc/bison.texinfo (Initial Action Decl): New.
9810 2004-09-20 Akim Demaille <akim@epita.fr>
9812 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
9813 clearer criterion to define it.
9814 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
9815 When reducing on an empty RHS, use the latest stacked location as
9817 yylloc is not always available.
9818 * data/glr.c: Likewise.
9819 Also, honor initial-actions.
9821 2004-09-20 Akim Demaille <akim@epita.fr>
9823 * data/yacc.c (YY_LOCATION_PRINT): New.
9824 Define when we know YYLTYPE's structure, i.e., when the default
9825 YYLLOC_DEFAULT is used.
9826 * data/c.m4 (b4_yysymprint_generate): Use it.
9827 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
9828 value of the result.
9829 (error_start_): Replace with...
9830 (error_range_): this location array.
9831 This allows to replace code relying on the implementation of
9832 locations by portable code.
9833 * data/yacc.c (yylerrsp): Replace with...
9834 (yyerror_range): this.
9835 Every time a token is popped, update yyerror_range[0], to have an
9836 accurate location for the error token.
9837 * data/glr.c (YY_LOCATION_PRINT): New.
9838 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
9839 deference a pointer.
9840 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
9841 report the location in %printers.
9843 * src/scan-skel.l: Instead of abort, report error messages to ease
9844 understanding skeleton scanning failures.
9846 2004-09-16 Akim Demaille <akim@epita.fr>
9848 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
9849 (iterator, const_iterator): these, to be more in the C++ spirit.
9850 Also, return reverse iterators so that when displaying the stack
9851 we display its bottom first.
9852 (Parser::stack_print_, Parser::reduce_print_): Match the messages
9854 We should probably use vector here though.
9856 2004-09-16 Akim Demaille <akim@epita.fr>
9858 Have more complete shift traces.
9860 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
9861 to report Shifts instead of ad hoc YYDPRINTF invocations,
9862 including for the error token.
9863 * data/lalr1.cc (symprint_): Output the location.
9864 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
9865 output the location within the %printer.
9866 Activate GLR tests, at least to make sure they compile properly.
9867 They still don't pass though.
9868 * tests/calc.at: Adjust expect verbose output, since now "Entering
9869 state..." is on a different line than the "Shifting" message.
9871 2004-09-08 Akim Demaille <akim@epita.fr>
9873 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
9874 Bison directive from the Bison file to the invocation of this
9875 macro, so that these directives are passed to
9876 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
9877 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
9878 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
9879 the extra Bison directives instead of the whole series.
9880 Change the grammar so that there are recoverable errors, and
9881 unrecoverable errors. Now we can have the parser give up before
9882 consuming the whole input. As a result we now can observe that
9883 the lookahead is freed when needed.
9884 Change the parser source to parse argv[1] instead of a hard coded
9886 Simplify yylex, and give a value and location to EOF.
9887 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
9888 passed directives already coded in the file.
9889 Add some tests to check the location of "error".
9890 For some tests, the C++ parser is correct, and not yacc.c.
9891 For other tests, they provide different, but unsatisfying, values,
9892 so keep the C++ value so that at least one parser is "correct"
9893 according to the test suite.
9894 (Actions after errors): Remove, this is subsumed by the
9895 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
9897 2004-09-06 Akim Demaille <akim@epita.fr>
9899 * data/lalr1.cc: Adjust the indentation of the labels.
9903 2004-09-06 Akim Demaille <akim@epita.fr>
9905 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
9906 argument, an informative message.
9907 Call YY_SYMBOL_PRINT.
9908 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
9909 * data/lalr1.cc (destruct_): Likewise.
9910 In addition, no longer depend on b4_yysymprint_generate and
9911 b4_yydestruct_generate to generate these functions, do it "by
9914 2004-09-03 Akim Demaille <akim@epita.fr>
9916 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
9917 invoked, yydestruct the lookahead.
9918 * tests/calc.at (Calculator $1): Update the expected lengths of
9919 traces: there is an added line for the discarded lookahead.
9920 * doc/bison.texinfo (Destructor Decl): Some rewording.
9921 Define "discarded" symbols.
9923 2004-09-02 Akim Demaille <akim@epita.fr>
9925 * data/lalr1.cc (translate_, destruct_): No reason to be static.
9927 2004-09-02 Akim Demaille <akim@epita.fr>
9929 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
9930 (YYDSYMPRINTF): Rename as...
9931 (YY_SYMBOL_PRINT): this.
9932 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
9934 Use it instead of direct symprint_ calls.
9935 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
9938 2004-09-02 Akim Demaille <akim@epita.fr>
9940 * data/lalr1.cc (b4_yysymprint_generate): New.
9941 (symprint_): New member function, defined when YYDEBUG.
9942 Use it consistently instead of token/nterm debugging output by
9944 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
9945 %printer calls to use cdebug_ when using lalr1.cc.
9947 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
9949 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
9950 with #ifdef YYDEBUG.
9952 2004-08-26 Akim Demaille <akim@epita.fr>
9954 * doc/bison.texinfo (Implementing Loops): Rename as...
9955 (Implementing Gotos/Loops): this.
9957 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
9959 Adjust to latest gnulib.
9960 * bootstrap (gnulib_modules): Add xalloc-die.
9961 Set LC_ALL=C so that file names sort consistently.
9962 Prefer the gnulib copies of gettext.m4, glibc21.m4,
9963 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
9964 uintmax_t.m4, ulonglong.m4.
9965 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
9966 po.m4 since we are now using _gl.m4 instead.
9968 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
9970 * src/scan-action.l: Remove. Scanning of semantic actions is
9971 handled in scan-gram.l.
9973 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
9975 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
9977 * src/location.h (struct): The file member is a uniqstr.
9978 (equal_boundaries): Use UNIQSTR_EQ for comparison.
9980 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
9982 Fix bug with non-%union parsers that have printers or destructors,
9983 which led to a Bison core dump. Reported by Peter Fales in
9984 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
9986 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
9987 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
9988 not to our own type.
9989 * src/output.c (symbol_destructors_output, symbol_printers_output):
9990 Don't assume %union.
9991 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
9992 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
9993 UNION-FLAG. All callers changed.
9994 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
9995 Use type char, not unsigned int, when declaring an array of char;
9996 this lets us remove a cast.
9997 (Printers and Destructors): Add non-%union test cases.
9999 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
10001 * doc/bison.texinfo: Minor editorial changes, mostly to the new
10002 GLR writeups. E.g., avoid frenchspacing and the future tense,
10003 change "lookahead" to "look-ahead", and change "wrt" to "with
10006 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
10008 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
10009 New sections, split off from the GLR Parsers section. Put the new
10010 Simple GLR Parser near the start of the GLR section, for clarity.
10011 Rewrite connective text.
10013 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
10015 * doc/bison.texinfo (Simple GLR Parsers): New section.
10017 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
10019 * NEWS, TODO, doc/bison.texinfo:

10042 2004-06-03 Paul Eggert <eggert@cs.ucla.edu>
10044 * README: Update location of patched M4 distribution.
10046 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
10048 Don't assume the C++ compiler takes the same arguments as the C compiler
10050 * configure.ac (O0CXXFLAGS): New var.
10051 * tests/atlocal.in (CXXFLAGS): Use it.
10053 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
10055 Fix some "make check" problems with C++ reported by
10056 Albert Chin-A-Young for Tru64 C++ in this thread:
10057 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html

10068 * tests/calc.at, tests/actions.at: Workaround for SGI
10069 C++ compiler. (trivial change)
10071 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
10073 Spent a few hours checking out which prerequisite versions the
10074 current sources actually require. I went all the way back to
10075 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
10076 a seemingly endless set of combinations of versions more recent
10077 than that. The bottom line is that the current sources require
10078 fairly recent versions of the build tools, and it'll be some work
10080 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
10081 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
10082 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
10083 Add comments explaining why those particular versions are
10086 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
10087 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
10088 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
10090 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
10091 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
10093 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
10095 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
10096 0.11.5. Suggested by Bruno Haible.
10097 * bootstrap: Remove gettext version checking.
10099 * doc/bison.texinfo (Decl Summary): Also mention that %union
10100 can depend on prerequisite types. Problem reported by Tim
10103 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
10105 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
10106 * README-alpha: Don't tell people not to package this.
10108 * bootstrap: Don't assume $(...) works; use `...` instead.
10109 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
10112 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
10113 put into the -d output file, and mention what to do if YYSTYPE is
10114 defined as a macro.
10116 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
10118 Undo change made earlier today: it caused autopoint to not bring
10119 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
10122 * bootstrap: Check that gettext version matches what's in
10123 configure.ac. Warn users to ignore robots.txt ERROR 404.
10124 * bootstrap: Undo today's earlier change (logged below).
10125 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
10127 The gettext version checking is causing more trouble than it's
10128 curing; remove it. Problem reported by Paul Hilfinger.
10130 * bootstrap: Issue a warning that one can expect a message
10131 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
10132 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
10134 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
10136 Ensure that the C++ compiler used for testing actually works on a
10137 simple test program; if not, skip the C++-related tests. Problem
10138 reported by Vin Shelton in:
10139 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
10141 * m4/cxx.m4: New file.

10146 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
10148 * data/glr.c (yylloc): Output this macro even if locations are not
10149 being generated, as the GLR parser needs it even in that case.
10150 Problem reported by Troy A. Johnson
10151 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
10153 * configure.ac (AC_INIT): Update to 1.875e.

10157 * NEWS: Version 1.875d.
10158 * configure.ac (AC_INIT): Likewise.
10159 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
10161 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
10162 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
10163 lalr1.cc runs afoul of the first, and the last two are no longer
10164 supported by GCC 3.4.0.
10165 * README: Mention GNU m4 1.4 or later; mention m4 patches.
10166 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
10168 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
10170 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not
10171 unsigned int, for compatibility with latest gnulib hash module.
10172 * src/state.c (state_hash, state_hasher): Likewise.
10173 * src/symtab.c (hash_symbol, hash_symbol_hasher): Likewise.
10174 * src/uniqstr.c (hash_uniqstr): Likewise.
10176 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
10178 * NEWS: Unescaped newlines are no longer allowed in char & strings.
10180 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER,
10181 SC_CHARACTER,SC_STRING>): Reject unescaped newlines in
10182 character and string literals.
10183 (unexpected_end): New function.
10184 (unexpected_eof): Use it.
10185 (unexpected_newline): New function.
10186 (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>): Coalesce duplicate
10189 * NEWS: Document %expect-rr.
10191 * bootstrap (--gnulib-srcdir=*, --cvs-user=*):
10192 Fix typo by replacing $1 with $option.
10193 Remove more 'intl'-related files.
10194 Don't DEFUN AM_INTL_SUBDIR twice.
10196 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
10197 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,
10199 * m4/.cvsignore: Add exitfail.m4, extensions.m4, gnulib.m4,
10200 hard-locale.m4, mbstate_t.m4, strerror_r.m4, strndup.m4,

10203 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
10204 * src/.cvsignore: Add *.output.
10206 * src/parse-gram.y: Put copyright notice inside %{ %} so it
10207 gets copied to the output file.
10209 2004-04-28 Paul Eggert <eggert@twinsun.com>
10211 Get files from the gnulib and po repositories, instead of relying
10212 on them being in our CVS. Upgrade to latest versions of gnulib
10215 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
10216 * bootstrap: Bootstrap from gnulib and po repositories.
10217 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
10218 * README-cvs: Document these changes. Remove version numbers from
10219 mentions of build tools, since they change so often. Mention Flex.
10221 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
10222 (gl_USE_SYSTEM_EXTENSIONS): Add.
10223 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
10224 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
10226 (AC_ISC_POSIX): Remove; we no longer support this
10227 ancient OS, as it gets in the way of latest Autoconf & gnulib.
10228 (AC_HEADER_STDC): Remove: we now assume C89 or better.
10229 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
10230 Do not check for C89 headers, except for locale.h which is used
10231 by the Yacc library and must port to K&R hosts.
10232 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
10233 Do not check for C89 functions, except for setlocale which is
10234 used by the Yacc library.
10235 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
10236 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,

10239 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
10240 AM_GNU_GETTEXT): Remove; now done by:
10241 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
10242 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
10245 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
10246 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
10247 Define to empty, as gnulib.mk will do the rest for us.
10248 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
10250 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
10251 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
10253 * src/files.c: Include gnulib's xstrndup.h.
10255 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
10256 (REALLOC): Use xnrealloc, for likewise.
10257 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
10258 (strnlen, memrchr): Remove decls; functions no longer used.
10259 Include <stpcpy.h>.

10282 Remove, as these files are now generated automatically
10283 by bootstrap or automake.
10285 * po/ChangeLog: Remove: all but one entry was a duplicate
10286 of this file, and I moved that 2000-11-02 entry here.
10288 * config/.cvsignore: Add Makefile, depcomp, install-sh.
10289 * lib/.cvsignore: Add alloca.c, alloca.h, alloca_.h, argmatch.c,

10304 * po/.cvsignore: Add *.po, LINGUAS, Makefile.in.in, Makevars.
10305 * src/.cvsignore: Remove *_.c.
10308 * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't
10309 support it. (The latest stable gzip doesn't.)
10311 2004-04-27 Paul Eggert <eggert@twinsun.com>
10313 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
10314 case, as stos_ is now used by destructors due to the 2004-02-09
10317 Remove more K&R C support.
10318 * lib/libiberty.y (PARAMS): Remove. All uses removed.
10319 * lib/subpipe.c (errno): Remove decl.
10320 Include <stdlib.h> unconditionally.
10321 (EXIT_FAILURE): Remove macro.
10322 * src/complain.c (vfprintf, strerror): Remove.
10323 * src/system.h: Include limits.h, stdlib.h, string.h, locale.h
10325 (EXIT_FAILURE, EXIT_SUCCESS, setlocale): Remove defns.
10326 Use latest Autoconf recommendations for including inttypes.h, stdint.h.
10327 (strchr, strspn, memchr): Remove decls.
10328 * tests/calc.at (_AT_DATA_CALC_Y): Include stdlib.h, string.h
10329 unconditionally. Do not declare perror.
10330 * tests/conflicts.at (%nonassoc and eof): Include stdlib.h
10333 * src/complain.c (_): Remove useless defn, as system.h defines this.
10335 * lib/bitset.h (__INT_TO_PTR): Remove; workaround no longer needed
10336 with latest obstack.h.
10337 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
10338 to procedure types, as obstack.h now does that for us.
10339 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
10341 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
10342 so that this include file can stand alone.
10343 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
10344 does this now. Include subpipe.h first after config.h, to
10345 test whether it can stand alone.
10347 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
10348 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
10349 unused declaration.
10351 * tests/synclines.at (%union synch line): Put a dummy member in
10352 the union, because empty unions aren't allowed in C. Caught
10355 2004-04-13 Jim Meyering <jim@meyering.net>
10357 * src/conflicts.c (conflicts_print): Correct format string typo:
10358 use `%%' to produce literal `%'. (trivial change)
10360 2004-03-30 Paul Eggert <eggert@twinsun.com>
10362 * src/getargs.c (version): Update copyright year to 2004.
10364 * data/c.m4 (b4_int_type): Use 'short int' rather than
10365 'short', and similarly for 'long', 'unsigned', etc.

10404 (declaration): Replace expected_conflicts with expected_sr_conflicts.
10405 Add %expect-rr rule.

10410 expected_conflicts.
10411 (expected_rr_conflicts): Declare.
10413 * src/conflicts.c (expected_sr_conflicts): Rename from
10414 expected_conflicts.
10415 (expected_rr_conflicts): Define.
10416 (conflicts_print): Check r/r conflicts against expected_rr_conflicts
10418 Use expected_sr_conflicts in place of expected_conflicts.
10419 Warn if expected_rr_conflicts used in non-GLR parser.
10421 * doc/bison.texinfo: Add documentation for %expect-rr.
10423 2004-03-08 Paul Eggert <eggert@gnu.org>
10425 Add support for hex token numbers. Suggested by Odd Arild Olsen in
10426 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
10428 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
10430 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
10431 * src/scan-gram.l (scan_integer): New function.
10433 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
10434 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
10435 handle_action_dollar, handle_action_at, convert_ucn_to_byte):
10436 Say "long int", not "long", for uniformity with GNU style.
10438 2004-02-25 Paul Eggert <eggert@twinsun.com>
10440 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
10441 compilers. This fixes a problem with Intel's C++ compiler being
10442 chatty, reported by Guido Trentalancia in
10443 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
10445 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>
10447 Support %destructor and merge error locations in lalr1.cc.
10449 * data/lalr1.cc (b4_cxx_destruct_def): New macro.
10450 (Parser::stos_): Define unconditionally.
10451 (Parser::destruct_): New method. Generate its body with
10452 b4_yydestruct_generate.
10453 (Parser::error_start_): New attribute.
10454 (Parser::parse) <yyerrlab, yyerrlab1>: Call destruct_ on erroneous
10455 token which are discarded.
10456 (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update
10457 error_start_ when erroneous token are discarded.
10458 (Parser::parse) <yyerrlab1>: Compute the location of the error
10459 token so that it covers all the discarded tokens.
10460 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
10461 it can be called with `%skeleton "lalr1.cc"', and do that.
10463 2004-02-02 Paul Eggert <eggert@twinsun.com>
10465 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
10466 $(top_srcdir)/lib and ../lib. This fixes a bug reported
10467 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
10468 There's no need to mention top_builddir since Automake does that
10470 (INCLUDES): Remove, as Automake says it's obsolescent.
10471 Contents migrated into AM_CPPFLAGS as described above.
10472 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
10474 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
10476 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
10477 (yyreportSyntaxError): Handle case where lookahead token is
10480 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
10482 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
10483 resulting parsers are compilable with C++.
10485 2003-12-23 Paul Eggert <eggert@twinsun.com>
10487 * config/depcomp, config/install-sh: Sync with Automake 1.8.
10488 * src/output.c (output_skeleton): Rename local var.
10489 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
10490 Bison tokens, as this runs afoul of the 2003-10-07 change that
10491 disallowed NUL bytes in character constants or string literals.
10493 * tests/local.at: Require Autoconf 2.59's Autotest.
10494 * tests/testsuite.at: Don't include local.at, since we now assume
10495 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
10497 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
10498 multiple inclusion warnings.
10500 2003-12-02 Akim Demaille <akim@epita.fr>
10502 * doc/bison.texinfo (How Can I Reset the Parser): More about start
10506 2003-11-18 Alexandre Duret-Lutz <adl@gnu.org>
10508 * doc/bison.texinfo (Bison Options): Escape `@' in `$@'.
10510 2003-10-07 Paul Eggert <eggert@twinsun.com>
10512 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
10513 if testsuite doesn't exist.
10515 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
10516 literals, unfortunately.
10517 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
10518 Complain about NUL bytes in character constants or string literals.
10520 2003-10-05 Paul Eggert <eggert@twinsun.com>
10522 * NEWS: Don't document %no-default-prec, as it's still
10524 * doc/bison.texinfo: Document %no-default-prec only if
10525 the defaultprec flag is set. Normally it's not.
10527 2003-10-04 Paul Eggert <eggert@twinsun.com>
10529 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
10530 non-modifiable lvalue, instead of a modifiable one.
10531 * doc/bison.texinfo (Actions): Document that $$ can
10532 be assigned to. Do not claim that $$ and $N are
10533 array element references: user code should not rely on this.
10535 2003-10-01 Paul Eggert <eggert@twinsun.com>
10537 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.
10538 (grammar_declaration): Use it.
10539 * src/scan-gram.l: New token %no-default-prec.
10540 * tests/conflicts.at: Revamp tests to use %no-default-prec.
10541 * NEWS, doc/bison.texinfo: Document the above.
10543 2003-10-01 Akim Demaille <akim@epita.fr>
10545 VCG no longer supports long_straight_phase.
10547 * src/vcg.c, src/vcg.h: Remove the handling of long_straight_phase.
10548 * src/print_graph.c (print_graph): Adjust.
10550 2003-09-30 Frank Heckenbach <frank@g-n-u.de>
10551 and Paul Eggert <eggert@twinsun.com>
10553 * doc/bison.texinfo (Decl Summary, Contextual Precedence,
10554 Table of Symbols): Document %default-prec.
10555 * src/parse-gram.y (PERCENT_DEFAULT_PREC): New token.
10556 (grammar_declaration): Set default_prec on %default-prec.
10557 * src/scan-gram.l (%default-prec): New token.
10558 * src/reader.h (default_prec): New flag.
10559 * src/reader.c: Likewise.
10560 (packgram): Handle it.
10561 * tests/conflicts.at (%default-prec without %prec,
10562 %default-prec with %prec, %default-prec 1): New tests.
10564 2003-09-30 Paul Eggert <eggert@twinsun.com>
10566 * tests/testsuite.at: Include local.at, not input.at, fixing
10567 a typo in the 2003-08-25 patch.
10569 2003-08-27 Akim Demaille <akim@epita.fr>
10571 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
10574 2003-08-26 Akim Demaille <akim@epita.fr>
10576 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
10577 "<\#" to avoid magic from Gnus when posting parts of this script.
10579 2003-08-26 Akim Demaille <akim@epita.fr>
10581 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
10582 (Parser::parse): here.
10583 Adjust: nerrs and errstatus is now replaced by...
10584 (Parser::nerrs_, Parser::errstatus_): New.
10586 2003-08-25 Akim Demaille <akim@epita.fr>
10588 * config/announce-gen, Makefile.cfg: New.
10589 * Makefile.am: Adjust.
10590 * GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
10591 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
10593 2003-08-25 Akim Demaille <akim@epita.fr>
10595 When reducing initial empty rules, Bison parser read an initial
10596 location that is not defined. This results in garbage, and that
10597 affects Bison's own parser. Therefore we need (i) to extend Bison
10598 to support a means to initialize this location, and (ii) to use
10599 this CVS Bison to fix CVS Bison's parser.
10601 * src/reader.h, reader.c (epilogue_augment): Remove, replace
10603 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
10604 * src/parse-gram.y: Adjust.
10605 (%initial-action): New.
10606 (%error-verbose): Since we require CVS Bison, there is no reason
10608 * src/scan-gram.l: Adjust.
10609 * src/Makefile.am (YACC): New, to make sure we use our own parser.
10610 * data/yacc.c (yyparse): Use b4_initial_action.
10612 2003-08-25 Akim Demaille <akim@epita.fr>
10614 * doc/bison.texinfo: Don't promote stdout for error messages.
10616 2003-08-25 Akim Demaille <akim@epita.fr>
10618 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
10619 From Alexandre Duret-Lutz.
10621 2003-08-25 Akim Demaille <akim@epita.fr>
10625 2003-08-25 Akim Demaille <akim@epita.fr>
10627 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
10630 2003-08-25 Akim Demaille <akim@epita.fr>
10632 * data/lalr1.cc (Parser::reduce_print_): New.
10635 2003-08-25 Akim Demaille <akim@epita.fr>
10637 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
10638 error recovery loops. This patch is based on
10639 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
10640 Also, augment the similarity between lalr1.cc and yacc.c.
10641 Note: the locations of error recovery rules are not correct yet.
10643 * data/lalr1.cc: Comment changes to augment the similarity between
10644 lalr1.cc and yacc.c.
10645 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
10646 (yyerrlab1): Remove, but where it used to be (now the bottom part of
10647 yyerrlab), when hitting EOF, pop the whole stack here instead of
10648 merely falling thru the default error handling mechanism.
10649 (yyerrorlab): New label, with the old contents of YYERROR,
10650 plus the following change: pop the stack of rhs corresponding
10651 to the production that invoked YYERROR. That is how Yacc
10652 behaves (required by POSIX).
10653 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
10656 2003-08-25 Akim Demaille <akim@epita.fr>
10658 Tune local.at so that people can "autom4te -l autotest calc.at -o
10659 calc" for instance, to extract a sub test suite.
10661 * tests/testsuite.at: Move the initialization, Autotest version
10662 requirement, and AT_TESTED invocation into...
10663 * tests/local.at: here.
10664 * tests/testsuite.at: Include it for compatibility with Autoconf
10666 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
10669 2003-08-04 Paul Eggert <eggert@twinsun.com>
10671 Rework code slightly to avoid gcc -Wtraditional warnings.
10672 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
10673 The returned value is now stored in *YY0. All callers changed.
10674 * src/output.c (merge_output): Adjust to the above change.
10676 2003-07-26 Paul Eggert <eggert@twinsun.com>
10678 * data/glr.c (YYASSERT): New macro.
10679 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
10680 yyresolveStates, yyprocessOneStack):
10681 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
10682 Derived from a suggestion by Frank Heckenbach.
10684 2003-07-25 Paul Eggert <eggert@twinsun.com>
10686 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
10687 for portability to K&R C (after ansi2knr, presumably). See
10688 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
10689 by Frank Heckenbach, though I have omitted the structure-initialization
10690 part of his glr-knr.diff patch since I recall that the Portable
10691 C Compiler didn't require that change.
10693 Let the user specify how to allocate and free memory.
10694 Derived from a suggestion by Frank Heckenbach in

10696 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
10697 All uses of free, malloc, realloc changed to use these macros,
10698 and unnecessary casts removed.
10699 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
10701 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
10703 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
10704 use s.empty() rather than s == "" to test for empty string; see
10705 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
10708 2003-06-25 Akim Demaille <akim@epita.fr>
10710 * config/depcomp, config/install-sh: Update from masters.
10712 2003-06-20 Paul Eggert <eggert@twinsun.com>
10714 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
10715 and return properly parenthesized result.
10716 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
10717 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
10718 Remove unnecessary parentheses from uses.

10720 conventions for parentheses.
10722 2003-06-19 Paul Eggert <eggert@twinsun.com>
10724 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
10725 yyreportTree): Do not assume that size_t is the same width as int,
10726 when printing sizes. Print sizes using an unsigned format.
10727 Problem reported by Frank Heckenbach in
10728 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
10730 Port to Forte Developer 7 C compiler.
10731 * data/glr.c (struct YYLTYPE): If locations are not being used,
10732 declare a single dummy member, as empty structs do not conform
10734 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
10735 the Forte Developer 7 C compiler complains that end-of-loop
10736 code is not reached.
10738 2003-06-17 Paul Eggert <eggert@twinsun.com>
10740 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
10741 avoid warnings from picky compilers about redefinition of PARAMS.
10743 2003-06-17 Paul Eggert <eggert@twinsun.com>
10747 * NEWS: Document 1.875b.
10749 * lib/bbitset.h: Do not include config.h; that's the includer's job.
10750 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
10751 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
10752 Don't use 'index' in comments, as it's a builtin fn on some hosts.
10753 * lib/bitset_stats.c: Include gettext.h unconditionally, as
10754 per recent gettext manual's suggestion.
10755 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
10756 Use prototypes, not old-style definitions.
10757 * lib/lbitset.c (lbitset_unused_clear): Likewise.

10772 Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
10773 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>
10774 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
10775 * lib/vbitset.c, lib/vbitset.h: New files.
10776 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
10777 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
10780 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
10781 `How Can I Reset @code{yyparse}', since texinfo does not allow
10782 arbitrary @ in node names.
10784 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
10785 shouldn't be needed according to the gettext 0.12.1 documentation
10786 but which seem to be needed anyway: codeset.m4 glibc21.m4
10787 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
10788 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.

10792 * m4/.cvsignore: Add nls.m4, po.m4.
10794 Upgrade to CVS gnulib.
10795 * stdbool_.h: File renamed from stdbool.h.in.
10796 * configure.ac (AM_STDBOOL_H): Invoke this instead of
10798 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
10799 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
10800 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
10801 (MOSTLYCLEANFILES): New var.
10802 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).

10809 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
10810 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
10811 the tests right now.
10812 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
10813 yyerror are declared before use; C99 requires this.
10815 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
10817 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
10819 (yyrecoverSyntaxError): Correct the logic for setting and testing
10821 Correct comment on handling EOF.
10822 Allow states with only a default reduction, rather than failing
10823 (I can't quite reconstruct why these were not allowed before).
10825 Fixes to avoid problem that $-N rules in GLR parsers can cause
10826 buffer overruns, corrupting state.
10828 * src/output.c (prepare_rules): Output max_left_semantic_context
10830 * src/reader.h (max_left_semantic_context): New variable declaration.
10831 * src/scan-gram.l (max_left_semantic_context): Define.
10832 (handle_action_dollar): Update max_left_semantic_context.
10833 * data/glr.c (YYMAXLEFT): New definition.
10834 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
10835 (yyresolveAction): Ditto.
10837 Fixes to problems with location handling in GLR parsers reported by
10838 Frank Heckenbach (2003/06/05).
10840 * data/glr.c (YYLTYPE): Make trivial if locations not used.
10841 (YYRHSLOC): Add parentheses, and define only if locations used.
10842 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
10843 locations not used.
10844 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
10845 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
10847 * tests/cxx-type.at: Exercise location information; update tests
10848 to differentiate output with and without locations.
10849 Remove forward declarations of yylex and yyerror---caused errors
10850 because default YYLTYPE not yet defined.
10851 Change semantic actions to compute strings, rather than printing
10852 them directly (to test proper passing of semantics values). Change
10853 output to prefix notation and update test data and expected results.
10854 (yylex): Track locations.
10855 (stmtMerge): Return value rather than printing, and include arguments
10858 2003-06-03 Paul Eggert <eggert@twinsun.com>
10860 Avoid warnings generated by GCC 2.95.4 when Bison is
10861 configured with --enable-gcc-warnings.
10862 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
10863 yy::]b4_parser_class_name[::translate_,
10864 yy::Stack::operator[] (unsigned),
10865 yy::Stack::operator[] (unsigned) const,
10866 yy::Slice::operator[] (unsigned),
10867 yy::Slice::operator[] (unsigned) const):
10868 Rename local vars to avoid warnings.
10869 * tests/glr-regression.at (Improper handling of embedded actions
10870 and $-N in GLR parsers): Remove unused local variable from yylex.
10871 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
10872 (void) as arg when not pure, since we now assume C89 when building
10873 Bison. Pacify GCC by using parameter.
10875 2003-06-02 Paul Eggert <eggert@twinsun.com>
10877 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
10878 yy::Location::lines, yy::Location::columns): Rename arguments
10879 to avoid shadowing; this removes a warning generated by GCC 3.3.
10881 2003-06-01 Paul Eggert <eggert@twinsun.com>
10883 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
10884 to g++, as GCC 3.3 complains if you do it.
10885 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
10886 everything that WARNING_CFLAGS has, except omit warnings
10887 not suitable for C++.
10888 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
10889 * tests/atlocal.in (CXXFLAGS): New var.
10890 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
10892 Fix a GLR parser bug I reported in February; see
10893 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
10894 The problem was that GLR parsers did not conform to the C standard,
10895 because actions like { $1 = $2 + $3; } expanded to expressions
10896 that invoked YYFILL in separate subexpressions, and YYFILL assigned
10897 to a local variable. The C standard says that expressions
10898 like (var = f ()) + (var = f ()) have undefined behavior.
10899 Another problem was that GCC sometimes issues warnings that
10900 yyfill and its parameters are unused.
10902 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
10903 as possibly unused.
10904 (yyfill): New function.
10906 (yyuserAction): Change type of yynormal to bool, so that it matches
10907 the new yyfill signature. Mark it as possibly unused.
10910 Follow up on a bug I reported in February, where a Bison-generated
10911 parser can loop. Provide a test case and a fix for yacc.c. I
10912 don't have a fix for lalr1.cc or for glr.c, unfortunately.
10913 The original bug report is in:
10914 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
10916 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
10917 macro's size was becoming unwieldy.
10918 (yyerrlab): Do not discard an empty lookahead symbol, as this
10919 might destroy garbage.
10920 (yyerrorlab): New label, with the old contents of YYERROR,
10921 plus the following change: pop the stack of rhs corresponding
10922 to the production that invoked YYERROR. That is how Yacc
10923 behaves, and POSIX requires this behavior.
10924 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
10925 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
10926 Define 'alarm' to do nothing if unistd.h is not available.
10927 Add a new rule "exp: '-' error;" to test the above change to
10928 data/yacc.c. Use 'alarm' to abort any test taking longer than
10929 10 seconds, as it's probably looping.
10930 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
10931 Also, the new yacc.c generates two fewer diagnostics for an
10934 2003-05-24 Paul Eggert <eggert@twinsun.com>
10936 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
10937 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
10938 This fixes a problem reported by John Bowman when the Compaq/HP
10939 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
10940 -ansi -Wall -gall).
10941 * data/yacc.c (union yyalloc): Likewise.
10942 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
10944 Switch from 'int' to 'bool' where that makes sense.
10946 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
10947 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,

10949 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
10950 Return or accept bool, not int. All callers changed.
10951 * lib/bbitset.h: (bitset_toggle_, bitset_copy_, bitset_and_or_cmp_,
10952 bitset_andn_or_cmp_, bitset_or_and_cmp_): Likewise.
10953 * lib/bitset.c (bitset_only_set_p, bitset_print, bitset_toggle_,

10961 bitset_stats_and_or_cmp, bitset_stats_andn_or_cmp,
10962 bitset_stats_or_and_cmp): Likewise.

10964 ebitset_test, ebitset_empty_p, ebitset_subset_p, ebitset_disjoint_p,
10965 ebitset_op3_cmp, ebitset_and_cmp, ebitset_andn_cmp, ebitset_or_cmp,
10966 ebitset_xor_cmp): Likewise.

10969 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
10970 lbitset_xor_cmp): Likewise.
10971 * lib/bbitset.h: Include <stdbool.h>.
10972 (struct bitset_vtable): The following members now return bool, not
10973 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
10974 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
10976 * src/conflicts.c (count_rr_conflicts): Likewise.
10977 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
10979 * lib/ebitset.c (ebitset_obstack_init): Likewise.
10980 * lib/lbitset.c (lbitset_obstack_init): Likewise.
10981 * src/getargs.c (debug_flag, defines_flag, locations_flag,

10991 * src/getargs.c (LOCATIONS_OPTION): New constant.
10992 (long_options, getargs): Use it.
10993 * src/lalr.c (build_relations): Use bool, not int.
10994 * src/nullable.c (nullable_compute): Likewise.
10995 * src/print.c (print_reductions): Likewise.

10997 * src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro.
10998 * src/output.c (prepare): Use it.
10999 * src/output.c (token_definitions_output,

11001 not boolean integer, to keep track of whether to output separator.
11002 * src/print_graph.c (print_core): Likewise.
11003 * src/state.c (state_rule_lookaheads_print): Likewise.
11005 * config/install-sh: Sync from automake 1.7.5.
11007 2003-05-14 Paul Eggert <eggert@twinsun.com>
11009 * src/parse-gram.y (rules_or_grammar_declaration): Require a
11010 semicolon after a grammar declaration, in the interest of possible
11011 future changes to the Bison input language.
11012 Do not allow a stray semicolon at the start of the grammar.
11013 (rhses.1): Allow one or more semicolons after any rule, including
11014 just before "|" as required by POSIX.
11015 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
11018 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
11020 %parse-param support for lalr1.cc.
11022 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
11023 b4_cc_constructor_calls, b4_cc_constructor_call,
11024 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
11026 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
11027 parse-param arguments.
11028 (yy::b4_parser_class_name): Declare instance variables to
11029 hold parse-param arguments.
11030 * tests/calc.at: s/value/semantic_value/ because value clashes
11031 with a member of yy::b4_parser_class_name. Adjust C++ code
11032 to handle %parse-param. Enable %parse-param test in C++.
11034 2003-05-12 Paul Eggert <eggert@twinsun.com>
11036 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
11037 English a bit. Fix fclose typo. Change "const char" to "char
11038 const", and use ANSI C rather than K&R for "main". Suggest
11039 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
11040 and suggest yy_switch_to_buffer.
11042 2003-05-05 Paul Eggert <eggert@twinsun.com>
11044 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
11045 C89. This avoids a diagnostic on compilers that define __STDC__
11046 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
11047 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
11049 2003-05-03 Paul Eggert <eggert@twinsun.com>
11051 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
11052 Do not overrun array bounds.
11053 This should fix a bug reported today by Olatunji Oluwabukunmi in
11054 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
11056 2003-04-29 Akim Demaille <akim@epita.fr>
11058 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
11059 * src/getargs.c, src/getargs.h: here, as bool, not int.
11060 (nondeterministic_parser): New.
11061 * src/parse-gram.y, src/scan-gram.l: Support
11062 %nondeterministic-parser.
11063 * src/output.c (prepare): Use nondeterministic_parser instead
11064 of glr_parser where appropriate.
11065 * src/tables.c (conflict_row, action_row, save_row)
11066 (token_actions, token_actions, pack_vector): Ditto.
11068 2003-04-29 Akim Demaille <akim@epita.fr>
11070 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
11072 2003-04-29 Akim Demaille <akim@epita.fr>
11074 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
11075 with %pure-parser and %locations to exercise the patch from Yakov
11078 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
11080 * data/yacc.c: (b4_lex_param): Corrected for the case where
11081 %lex-param is provided and %pure-parser isn't.
11083 2003-04-27 Paul Eggert <eggert@twinsun.com>
11085 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
11086 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
11087 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
11088 if it is not defined.
11089 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
11091 2003-04-26 Paul Eggert <eggert@twinsun.com>
11093 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
11094 Declare to be of type suitable for the ninf value itself, not of
11095 type suitable for the corresponding table, since the latter might
11096 be unsigned but the ninf value might be negative. This fixes a
11097 bug reported by Alexandre Duret-Lutz in
11098 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
11100 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
11101 invokes it. We shouldn't invoke it twice because it will attempt
11102 to put error.o in the archive twice. This fixes a glitch reported
11103 by Martin Mokrejs in
11104 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
11106 2003-04-21 Paul Eggert <eggert@twinsun.com>
11108 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
11111 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
11113 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
11114 Fix obvious typo that results in uncompilable GLR parsers
11115 when both %pure-parser and %locations are used. (trivial change)
11117 2003-04-17 Paul Eggert <eggert@twinsun.com>
11119 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
11120 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
11121 Do not insert the expected token via unput, as this runs afoul
11122 of a POSIX-compatibility bug in flex 2.5.31.
11123 All uses changed to BEGIN the parent state,
11124 since we no longer insert the expected token via unput.
11125 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
11126 that is no longer emitted after the above change.
11128 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
11129 the first one. This change is from Paul Hilfinger, and it fixes
11130 regression reported by Werner Lemberg in
11131 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
11133 (resolve_sr_conflict): Don't invoke state_errs_set
11134 unless one or more tokens have been explicitly made errors.
11135 Otherwise, the above change causes Bison to abort.
11137 * tests/existing.at (GNU pic Grammar): New test case, taken from
11140 2003-03-31 Akim Demaille <akim@epita.fr>
11142 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
11144 2003-03-31 Akim Demaille <akim@epita.fr>
11146 * src/output.c (prepare_symbols): Avoid trailing spaces in the
11149 2003-03-31 Akim Demaille <akim@epita.fr>
11151 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
11152 From Paul Hilfinger.
11154 2003-03-29 Akim Demaille <akim@epita.fr>
11156 * m4/error.m4: Do not put under dynamic conditions some code which
11157 expansion is under static control.
11159 2003-03-29 Akim Demaille <akim@epita.fr>
11161 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
11163 2003-03-29 Akim Demaille <akim@epita.fr>
11165 * doc/bison.texinfo (Strings are Destroyed): New.
11167 2003-03-13 Paul Eggert <eggert@twinsun.com>
11169 * .cvsignore: Add configure.lineno.
11170 * src/.cvsignore: Add yacc.
11171 * tests/.cvsignore: Add testsuite.log.
11172 * doc/fdl.texi: Sync with latest FSF version.
11174 2003-03-12 Paul Eggert <eggert@twinsun.com>
11176 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
11177 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
11178 cursor, instead of leaving it undefined. This fixes a bug
11179 reported by Tim Van Holder in
11180 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
11181 * tests/input.at (Torturing the Scanner): Test the scanner on
11182 an empty input file, which was Tim Van Holder's test case.
11184 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
11185 <sys/resource.h> can be included, include sys/time.h and
11186 sys/times.h first, if available. This works around the SunOS
11187 4.1.4 porting bug reported by Bruce Becker in
11188 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
11190 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
11191 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
11192 AC_HEADER_SYS_WAIT.
11194 Merge changes from gnulib. This was prompted because the CVS
11195 snapshot didn't build on Solaris 7 due to strnlen problems.
11197 These changes need to be merged back into gnulib:
11198 * lib/hash.c: Include <stdbool.h> unconditionally.
11199 * m4/onceonly.m4 (m4_quote): New macro.
11200 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
11201 Quote AC_FOREACH variable-expansions properly.
11202 The 2003-01-03 obstack.h change also needs merging.
11203 {end of changes requiring merging}
11205 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
11206 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,

11210 New files, imported from gnulib.
11211 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
11214 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
11215 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
11218 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
11220 (gl_ERROR): New, replacing jm_PREREQ_ERROR.

11224 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
11225 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
11226 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
11227 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
11228 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
11229 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
11230 (jm_PREREQ_ARGMATCH): Remove.
11231 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
11232 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
11234 * src/system.h: Include <stdbool.h> unconditionally.
11236 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
11237 assuming at least C89 in the bitset code for some time now.
11239 2003-03-03 Akim Demaille <akim@epita.fr>
11243 2003-03-02 Akim Demaille <akim@epita.fr>
11245 * doc/bison.texinfo (Table of Symbols): Reactivate the
11246 documentation for %lex-param, and %parse-param.
11248 2003-03-02 Akim Demaille <akim@epita.fr>
11250 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
11251 generate verbose error messages.
11252 Use the number of tokens as an upper bound in yytname, as it
11253 cannot be a non terminal.
11255 2003-03-02 Akim Demaille <akim@epita.fr>
11257 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
11260 2003-03-02 Akim Demaille <akim@epita.fr>
11262 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
11263 Use them to exercise yycheck overrun.
11264 Based on Andrew Suffield's grammar.
11266 2003-03-02 Akim Demaille <akim@epita.fr>
11268 Create tests/local.at for Bison generic testing macros.
11270 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...

11274 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
11275 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
11276 * tests/local.at: here.
11277 (AT_COMPILE_CXX): Tags the tests using it as c++.
11278 Ignore the test if CXX is not functional.
11280 2003-03-01 Paul Eggert <eggert@twinsun.com>
11282 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
11283 not loc->end, since loc->end might contain garbage and this leads
11284 to undefined behavior on some platforms.
11285 (id_loc, token_start): Use (IF_LINTed) initial values that do not
11286 depend on *loc, so that the reader doesn't give the the false
11287 impression that *loc is initialized.
11288 (<INITIAL>"%%"): Do not bother setting code_start, since its value
11289 does not survive the return.
11291 2003-03-01 Akim Demaille <akim@epita.fr>
11293 * src/scan-gram.l (code_start): Always initialize it when entering
11294 into yylex, as SC_EPILOGUE is activated *before* the corresponding
11295 yylex invocation. An alternative would be making it static, but
11296 then it starts with the second %%'s beginning, instead of its end.
11298 2003-02-28 Paul Eggert <eggert@twinsun.com>
11300 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
11301 around a UnixWare 7.1.1 porting bug reported by John Hughes in
11302 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
11304 2003-02-26 Paul Eggert <eggert@twinsun.com>
11306 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
11307 Remove Sequent/Pyramid discussion (nobody uses them any more).
11308 Merge VMS and MS-DOS discussion; these ports may well be dead
11309 but let's keep mentioning them for now. Put <> around email
11310 addresses. Add copyright notice.
11312 2003-02-24 Paul Eggert <eggert@twinsun.com>
11314 * data/glr.c (yy_reduce_print): yylineno -> yylno,
11315 to avoid collision with flex use of yylineno.

11326 change integer types.
11327 Suggested by Paul Eggert.
11329 2003-02-21 Akim Demaille <akim@epita.fr>
11331 * doc/bison.texinfo: Use "location" consistently to refer to @n,
11332 to avoid confusions with lalr1.cc's notion of Position.
11333 Suggested by Paul Eggert.
11335 2003-02-20 Akim Demaille <akim@epita.fr>
11337 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
11338 before initial_columns.
11339 (location.hh): Use consistent variable names when defining the
11341 Use "last" so that we subtract from Positions, not from unsigned.
11343 2003-02-20 Akim Demaille <akim@epita.fr>
11345 * data/lalr1.cc (position.hh): New subfile, including the extended
11346 and Doxygen'ed documentation of class Position.
11347 (location.hh): Use it.
11348 Document a` la Doxygen.

11358 Don't use the location in yy::Parser::error_ and
11359 yy::Parser::print_ when not %locations.
11360 Activate more lalr1.cc tests.
11362 2003-02-19 Akim Demaille <akim@epita.fr>
11364 * data/lalr1.cc: When displaying a line number, be sure to make it
11367 2003-02-19 Akim Demaille <akim@epita.fr>
11369 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
11371 (YYABORT, YYACCEPT, YYERROR): New.
11372 * tests/calc.at: Renable the lalr1.cc test.
11374 2003-02-19 Akim Demaille <akim@epita.fr>
11376 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
11377 error recovery, mixing with/without pops and discarding of the

11394 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
11395 Check for malloc failure, for consistency with yacc.c.
11396 (yytname_size): Remove, for consistency with yacc.c.
11398 The bug still remains in data/lalr1.cc, as I didn't have time
11401 2003-02-06 Akim Demaille <akim@epita.fr>

11518 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
11521 Changes in response to error report by S. Eken: GLR mode does not
11522 handle negative $ indices or $ indices in embedded rules correctly.
11523 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.

11551 * data/lalr1.cc: Do not use @output_header_name@ unless
11552 b4_defines_flag is set. This fixes two bugs reported by
11554 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
11555 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
11557 2003-01-21 Paul Eggert <eggert@twinsun.com>
11559 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
11560 we don't need to worry about yyerrlab1 being reported as an
11561 "unused label" by non-GCC C compilers. The downside is that if
11562 locations are used then a couple of statements are duplicated each
11563 time YYERROR is invoked, but the upside is that the warnings
11565 (yyerrlab1): Move code to YERROR.
11566 (yyerrlab2): Remove. Change uses back to yyerrlab1.
11567 This reverts some of the 2002-12-27 change.
11569 2003-01-17 Paul Eggert <eggert@twinsun.com>
11571 * src/output.c (symbol_printers_output): Fix typo that led
11572 to core dump. Problem reported by Antonio Rus in
11573 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
11575 2003-01-13 Akim Demaille <akim@epita.fr>,
11576 Quoc Peyrot <chojin@lrde.epita.fr>,
11577 Robert Anisko <anisko_r@lrde.epita.fr>
11579 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
11580 when the stacks contain one element, as the loop would otherwise
11581 free the last state, and then use the top state (the one we just
11582 popped). This means that the initial elements will not be freed
11583 explicitly, as is the case in yacc.c; it is not a problem, as
11584 these elements have fake values.
11586 2003-01-11 Paul Eggert <eggert@twinsun.com>
11588 * NEWS: %expect-violations are now just warnings, reverting
11589 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
11590 bootstrapping problem reported by Matthias Klose; see
11591 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
11592 * src/conflicts.c (conflicts_print): Likewise.
11593 * tests/conflicts.at (%expect not enough, %expect too much,
11594 %expect with reduce conflicts): Likewise.
11595 * doc/bison.texinfo (Expect Decl): Document this. Also mention
11596 that the warning is enabled if the number of conflicts changes
11597 (not necessarily increases).
11599 * src/getargs.c (version): Update copyright year.
11601 2003-01-09 Akim Demaille <akim@epita.fr>
11603 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
11605 2003-01-08 Paul Eggert <eggert@twinsun.com>
11607 * Makefile.maint (WGETFLAGS):
11608 New macro, containing "-C off" to disable proxy caches.
11609 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
11610 (rel-check): Use $(WGET) instead of wget.
11612 2003-01-06 Paul Eggert <eggert@twinsun.com>
11614 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
11615 the GLR paper of Scott, Johnstone and Hussain.
11617 2003-01-04 Paul Eggert <eggert@twinsun.com>
11619 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
11620 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
11621 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
11622 (EXTRA_LIBRARIES): New var, for liby.a.
11623 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
11624 (EXTRA_SCRIPTS): New var, for yacc.
11626 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
11627 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
11628 Problem reported by Nelson H. F. Beebe.
11630 2003-01-03 Paul Eggert <eggert@twinsun.com>
11632 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
11633 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
11634 when compiling Bison 1.875's `bitset bset = obstack_alloc
11635 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
11637 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
11638 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
11639 grow to a huge size with typical invocation.
11641 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
11642 Use the pattern recommended by Autoconf 2.57, except also protect
11643 against double-definition.
11644 * src/system.h: Likewise.
11645 Portability issues reported by Nelson H. F. Beebe.
11647 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
11648 All uses changed. Provide a definition in both C and C++.
11649 (yytrue, yyfalse): Define even if defined (__cplusplus).
11651 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
11652 Reported by Nelson H. F. Beebe.
11654 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
11656 2003-01-02 Paul Eggert <eggert@twinsun.com>
11658 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
11659 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
11660 Bug reported by Nelson H. F. Beebe.
11662 2003-01-01 Paul Eggert <eggert@twinsun.com>
11666 2002-12-30 Paul Eggert <eggert@twinsun.com>
11668 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
11670 (<INITIAL>","): Here. This causes stray "," to be treated
11673 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
11674 last brace in braced code when not in Yacc mode, for compatibility
11675 with Bison 1.35. This resurrects the 2001-12-15 patch to
11678 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
11679 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
11681 2002-12-28 Paul Eggert <eggert@twinsun.com>
11683 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
11684 that of SYM's type. This fixes Debian bug 168069, reported by
11687 2002-12-28 Paul Eggert <eggert@twinsun.com>
11691 Switch back to the Yacc style of conflict reports, undoing some
11692 of the 2002-07-30 change.
11693 * doc/bison.texinfo (Understanding): Use Yacc style for
11694 conflict reports. Also, use new way of locating rules.
11695 * src/conflicts.c (conflict_report):
11696 Renamed from conflict_report_yacc, removing the old
11697 'conflict_report'. Translate the entire conflict report at once,
11698 so that we don't assume that "," has the same interpretation in
11700 (conflicts_output): Use Yacc-style conflict report for each state,
11701 instead of our more-complicated style.
11702 (conflicts_print): Use Yacc-style conflict report, except print
11703 the input file name when not emulating Yacc.
11704 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
11705 Conflicted Reduction, %expect not enough, %expect too much,
11706 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
11707 * tests/existing.at (GNU Cim Grammar): Likewise.
11708 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
11710 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
11711 fatal): Don't invoke fflush; it's not needed and it might even be
11712 harmful for stdout, as stdout might not be open.
11713 * src/reduce.c (reduce_print): Likewise.
11715 2002-12-27 Paul Eggert <eggert@twinsun.com>
11717 Fix a bug where error locations were not being recorded correctly.
11718 This problem was originally reported by Paul Hilfinger in
11719 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
11721 * data/yacc.c (yyparse): New local var yylerrsp, to record the
11722 top of the location stack's error locations.
11723 (yyerrlab): Set it. When discarding a token, push its location
11724 onto yylerrsp so that we don't lose track of the error's end.
11725 (yyerrlab1): Now is only the target of YYERROR, so that we can
11726 properly record the location of the action that failed. For GCC
11727 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
11728 GCC warning about yyerrlab1 being unused if YYERROR is unused.
11729 (yyerrlab2): New label, which yyerrlab now falls through to.
11730 Compute the error's location by applying YYLLOC_DEFAULT to
11731 the locations of all the symbols that went into the error.
11732 * doc/bison.texinfo (Location Default Action): Mention that
11733 YYLLOC_DEFAULT is also invoked for syntax errors.
11734 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
11735 Error locations include the locations of all the tokens that were
11736 discarded, not just the last token.
11738 2002-12-26 Paul Eggert <eggert@twinsun.com>
11740 * src/files.c: Include quote.h.
11741 (compute_output_file_names): Warn if we detect conflicting
11742 outputs to the same file. This should catch the misunderstanding
11743 exemplified by Debian Bug 165349, reported by Bruce Stephens..
11745 * src/conflicts.c (conflicts_print): If the user specifies
11746 "%expect N", report an error if there are any reduce/reduce
11747 conflicts. This is what the manual says should happen.
11748 This fixes Debian bug 130890, reported by Anthony DeRobertis.
11749 * tests/conflicts.at (%expect with reduce conflicts): New test.
11751 Don't use m4_include on relative file names, as it doesn't work as
11752 desired if there happens to be a file with that name under ".".
11754 * m4sugar/version.m4: Remove; it was included but it wasn't used.
11755 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
11756 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
11757 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
11758 * src/output.c (output_skeleton): Use full path names when
11759 specifying a file to include; don't rely on include path, as
11760 it's unreliable when the working file contains a file with
11763 2002-12-25 Paul Eggert <eggert@twinsun.com>
11765 Remove obsolete references to bison.simple and bison.hairy.
11766 Problem mentioned by Aubin Mahe in
11767 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
11768 * data/glr.c: Comment fix.
11769 * doc/bison.1: Remove references. Also, mention "yacc".
11771 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
11774 * src/parse-gram.y (declaration): Use enum "report_states" rather
11775 than its numeric value 1.
11777 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
11778 opening a new one. This fixes Debian bug 165349, reported by
11781 2002-12-24 Paul Eggert <eggert@twinsun.com>
11785 * Makefile.maint (cvs-update): Don't assume that the shell
11786 supports $(...), as Solaris sh doesn't.
11788 * src/parse-gram.y (lloc_default): Remove test for empty
11789 nonterminals at the end, since it didn't change the result.
11791 2002-12-24 Paul Eggert <eggert@twinsun.com>
11793 If the user does not define YYSTYPE as a macro, Bison now declares it
11794 using typedef instead of defining it as a macro. POSIX requires this.
11795 For consistency, YYLTYPE is also declared instead of defined.
11797 %union directives can now have a tag before the `{', e.g., the
11798 directive `%union foo {...}' now generates the C code
11799 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
11800 The default union tag is `YYSTYPE', for compatibility with Solaris 9
11801 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
11802 instead of `yyltype'.
11804 `yystype' and `yyltype' are now obsolescent macros instead of being
11805 typedefs or tags; they are no longer documented and will be
11806 withdrawn in a future release.
11808 * data/glr.c (b4_location_type): Remove.
11809 (YYSTYPE): Renamed from yystype.
11810 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
11811 (struct YYLTYPE): Renamed from struct yyltype.
11812 (YYLTYPE): Renamed from yyltype.
11813 (yyltype, yystype): New (and obsolescent) macros,
11814 for backward compatibility.
11815 * data/yacc.c: Likewise.
11817 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
11818 does not specify a union tag. This is for compatibility with
11821 * src/parse-gram.y (add_param): 2nd arg is now char * not char
11822 const *, since it is now modified by stripping surrounding { }.
11823 (current_braced_code): Remove.
11824 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
11825 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
11826 trailing " {...}". Now of type <chars>.
11827 (grammar_declaration): Adjust to bundled tokens.
11828 (code_content): Remove; stripping is now done by add_param.
11829 (print_token_value): Print contents of bundled tokens.
11830 (token_name): New function.
11832 * src/reader.h (braced_code, current_braced_code): Remove.
11833 (token_name): New decl.
11835 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
11836 token_type, not braced_code code_kind. All uses changed.
11837 (SC_PRE_CODE): New state, for scanning after a keyword that
11838 has (or usually has) an immediately-following braced code.
11839 (token_type): New local var, to keep track of which token type
11840 to return when scanning braced code.
11841 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
11842 <INITIAL>"%parse-param", <INITIAL>"%printer",
11843 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
11844 instead of returning a token type immediately.
11845 (<INITIAL>"{"): Set token type.
11846 (<SC_BRACED_CODE>"}"): Use it.
11847 (handle_action_dollar, handle_action_at): Now returns bool
11848 indicating success. Fail if ! current_rule; this prevents a core dump.
11849 (handle_symbol_code_dollar, handle_symbol_code_at):
11850 Remove; merge body into caller.
11851 (handle_dollar, handle_at): Complain in invalid contexts.
11853 * NEWS, doc/bison.texinfo: Document the above.
11854 * NEWS: Fix years and program names in copyright notice.
11856 2002-12-17 Paul Eggert <eggert@twinsun.com>
11858 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
11859 Reporting, Table of Symbols): Omit mentions of %lex-param and
11860 %parse-param from the documentation for now.
11862 2002-12-15 Paul Eggert <eggert@twinsun.com>
11864 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
11865 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
11866 lookahead symbol, and which sets yychar in parser actions) and it
11867 disagreed with the Bison documentation. Bug
11868 reported by Andrew Walrond.
11870 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
11871 as the caller now does that.
11872 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
11873 (YYEMPTY): Parenthesize right hand side, since others use it.
11874 (yyparse): Don't assume that our generated code is the only code
11877 2002-12-13 Paul Eggert <eggert@twinsun.com>
11881 POSIX requires a "yacc" command.
11882 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
11883 (MOSTLYCLEANFILES): Add yacc.
11885 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
11886 as an alias for bison y.
11888 * po/LINGUAS: Add da.
11890 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
11891 problem with latest <getopt.h>.
11892 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
11894 * doc/fdl.texi: Upgrade to 1.2.
11895 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
11896 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
11897 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
11899 * config/install-sh: Sync with autotools.
11901 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
11902 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
11903 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
11904 locations are requested.
11905 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
11906 locations are requested.
11908 2002-12-12 Paul Eggert <eggert@twinsun.com>
11910 Remove unportable casts and storage allocation tricks.
11911 While we're at it, remove almost all casts, since they
11912 usually aren't needed and are a sign of trouble.
11914 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
11916 * src/derives.c (derives_compute): Do not subtract NTOKENS from
11917 the pointer DSET returned by malloc; this isn't portable.
11918 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
11919 Similarly for DERIVES.
11920 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
11921 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
11922 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
11924 * src/derives.c (derives_compute): Do not bother invoking
11925 int_of_rule_number, since rule numbers are integers.
11927 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
11928 rather than XMALLOC (char, N).
11930 * src/files.c (filename_split): Rewrite to avoid cast.
11932 * src/gram.h (symbol_number_as_item_number,
11933 item_number_as_symbol_number, rule_number_as_item_number,
11934 item_number_as_rule_number):
11935 Now inline functions rather than macros, to avoid casts.
11936 * src/state.h (state_number_as_int): Likewise.
11937 * src/tables.c (state_number_to_vector_number,
11938 symbol_number_to_vector_number): Likewise.
11940 * src/gram.h (int_of_rule_number): Remove; no longer used.
11942 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
11943 since the resulting storage is always stored into.
11945 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
11948 * src/muscle_tab.c (muscle_m4_output):
11949 Now inline. Return bool, not int.
11950 * src/state.c (state_compare): Likewise.
11951 * src/symtab.c (symbol_check_defined,
11952 symbol_check_alias_consistency, symbol_pack, symbol_translation,
11953 hash_compare_symbol, hash_symbol):
11955 * src/uniqstr.c (uniqstr_print): Likewise.
11956 * src/muscle_tab.c (muscle_m4_output_processor):
11957 New function, to avoid casts.
11958 * src/state.c (state_comparator, stage_hasher): Likewise.
11959 * src/symtab.c (symbol_check_defined_processor,
11960 symbol_check_alias_consistency_processor, symbol_pack_processor,
11961 symbol_translation_processor, hash_symbol_comparator,
11962 hash_symbol_hasher): Likewise.
11963 * src/uniqstr.c (uniqstr_print_processor): Likewise.
11964 * src/muscle_tab.c (muscles_m4_output):
11965 Use new functions instead of casting old functions unportably.
11966 * src/state.c (state_hash_new): Likewise.
11967 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
11968 symbols_token_translations_init):
11970 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
11972 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
11973 var instead of casting to long, to avoid casts.
11974 (prepare_states): Use MALLOC rather than alloca, so that we don't
11975 have to worry about alloca.
11976 * src/state.c (state_hash_lookup): Likewise.
11978 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
11979 local var instead of casting to unsigned char, to avoid casts.
11981 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
11982 STATE_ALLOC): Remove.
11983 (transitions_new, errs_new, reductions_new, state_new): Use malloc
11984 rather than calloc, and use offsetof to avoid allocating slightly
11986 (state_new): Initialize all members.
11988 * src/state.c (state_hash): Use unsigned accumulator, not signed.
11990 * src/symtab.c (symbol_free): Remove; unused.
11991 (symbol_get): Remove cast in lhs of assignment.
11992 (symbols_do): Now static. Accept generic arguments, not
11993 hashing-related ones.
11995 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
11996 (symbol_processor): Remove.
11997 (symbols_do): Remove decl; now static.
11999 * src/system.h (alloca): Remove; decl no longer needed.
12000 (<stddef.h>): Include, for offsetof.
12001 (<inttypes.>, <stdint.h>): Include if available.
12002 (uintptr_t): New type, if system lacks it.
12003 (CALLOC, MALLOC, REALLOC): New macros.
12004 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
12007 * src/tables.c (table_size): Now int, to pacify GCC.
12008 (table_grow, table_ninf_remap): Use signed table size.
12009 (save_row): Don't bother initializing locals when not needed.
12010 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
12011 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
12013 * src/vcg.h: Correct misspellings.

12018 * src/getargs.c (getargs): Don't assume EOF == -1.
12020 2002-12-09 Paul Eggert <eggert@twinsun.com>
12022 Change identifier spellings to avoid collisions with names
12023 that are reserved by POSIX.
12025 Don't use names ending in _t, since POSIX reserves them.
12026 For consistency, remove _e and _s endings -- they're weren't
12027 needed to remove ambiguity. All uses changed.
12028 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
12029 turn was just renamed from struniq_t.
12030 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
12031 which in turn was just renamed from struniq_processor_t.
12032 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which
12033 in turn was renamed from hash_compare_struniq_t.

12102 * tests/input.at (Torturing the Scanner): Rename value_t -> value,
12103 value_t_as_yystype -> value_as_yystype.
12105 Don't include <errno.h> in the mainstream code, since it
12106 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
12107 * lib/get-errno.c, lib/get-errno.h: New files.
12108 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
12110 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.
12111 * src/output.c (output_skeleton): Likewise.
12112 * src/scan-gram.l (<INITIAL>{int}): Use set_errno and get_errno

12117 * src/system.h: Do not include <errno.h>.
12118 (TAB_EXT): Renamed from EXT_TAB.
12119 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
12121 Avoid str[a-z]*, since <string.h> reserves that name space.
12122 Change all instances of "struniq" in names to "uniqstr", and
12123 likewise for "STRUNIQ" and "UNIQSTR".
12124 * src/uniqstr.c: Renamed from src/struniq.c.
12125 * src/uniqstr.h: Renamed from src/struniq.h.
12126 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.
12127 * src/files.c (strsuffix): Remove; unused.
12128 (concat2): Renamed from stringappend. Now static.
12129 * src/files.h (strsuffix, stringappend): Remove; unused.
12130 * src/parse-gram.y (<chars>): Renamed from <string>.
12131 (<uniqstr>): Renamed from <struniq>.

12136 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
12137 (N_EXPAND): Renamed from N_STRETCH.

12140 * data/yacc.c (YYSTACK_GAP_MAXIMUM): Renamed from YYSTACK_GAP_MAX.
12141 * src/gram.h (ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX):
12143 * src/lalr.h (GOTO_NUMBER_MAXIMUM): Renamed from GOTO_NUMBER_MAX.
12144 * src/state.h (STATE_NUMBER_MAXIMUM): Renamed from STATE_NUMBER_MAX.
12145 * src/symtab.h (SYMBOL_NUMBER_MAXIMUM): Renamed from SYMBOL_NUMBER_MAX.
12146 * src/tables.c (VECTOR_NUMBER_MAX, VECTOR_NUMBER_MIN): Remove; unused.
12147 (BASE_MAXIMUM): Renamed from BASE_MAX.
12148 (BASE_MINIMUM): Renamed from BASE_MIN.
12149 (ACTION_MAX): Remove; unused.
12150 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
12151 Unnecessary casts removed from above defines.
12154 Fix misspelling in names.
12155 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
12156 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
12160 * lib/timevar.c (timevar_report): Renamed from time_report,
12161 for consistency with other names.
12162 * lib/timevar.h (timevar_report): New decl.
12163 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
12166 Sort include-file uses.
12168 Reorder all include files under src to be in the order "system.h".
12169 then the ../lib include files in angle brackets (alphabetized),
12170 then the . include files in double-quotes (alphabetized). Fix
12171 dependency breakages encountered in this process, as follows:
12172 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
12173 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
12174 * src/state.h: Include "symtab.h".
12176 2002-12-08 Paul Eggert <eggert@twinsun.com>
12178 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
12179 since this causes problems when __file__ contains character
12180 sequences like "@" that are treated specially by src/scan-skel.l.
12181 Instead, just use the file's basename. This fixes the bug
12182 reported by Martin Mokrejs in
12183 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
12185 2002-12-06 Paul Eggert <eggert@twinsun.com>
12187 Add support for rules that do not have trailing semicolons, as
12188 POSIX requires. Improve the quality of locations in Bison
12191 * src/location.c: Include <quotearg.h>.
12192 (empty_location): Now const.
12193 (location_print): New function. Follow the recommendation of the
12194 GNU Coding Standards for locations that span file boundaries.
12195 * src/location.h: Do not include <quotearg.h>; no longer needed.
12196 (boundary): New type.
12197 (location_t): Use it. This allows locations to span file boundaries.
12198 All member uses changed: file -> start.file or end.file (as needed),
12199 first_line -> start.line, first_column -> start.column,
12200 last_line -> end.line, last_column -> end.column.
12201 (equal_boundaries): New function.
12202 (LOCATION_RESET, LOCATION_STEP): Remove.
12203 (LOCATION_PRINT): Remove. All callers changed to use location_print.
12204 (empty_location): Now const.
12205 (location_print): New decl.
12206 * src/parse-gram.y (lloc_default): New function, which handles
12207 empty locations more accurately.
12208 (YYLLOC_DEFAULT): Use it.
12209 (%token COLON): Remove.
12210 (%token ID_COLON): New token.
12212 (declarations, rules): Remove trailing semicolon.
12213 (declaration, rules_or_grammar_declaration):
12214 Allow empty (";") declaration.
12215 (symbol_def): Remove empty actions; no longer needed.
12216 (rules_or_grammar_declaration): Remove trailing semicolon.
12217 (semi_colon.opt): Remove.
12218 * src/reader.h: Include location.h.
12219 (scanner_cursor): New decl.
12220 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
12222 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
12224 (STEP): Remove. No longer needed, now that adjust_location does
12225 the work. All uses removed.
12226 (scanner_cursor): New var.
12227 (adjust_location): Renamed from extend_location. It now sets
12228 *loc and adjusts the scanner cursor. All uses changed.
12229 Don't bother testing for CR.
12230 (handle_syncline): Remove location arg; now updates scanner cursor.
12231 All callers changed.
12232 (unexpected_end_of_file): Now accepts start boundary of token or
12233 comment, not location. All callers changed. Update scanner cursor,
12235 (SC_AFTER_IDENTIFIER): New state.
12236 (context_state): Renamed from c_context. All uses changed.
12237 (id_loc, code_start, token_start): New local vars.
12238 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
12239 processing of Yacc white space and equivalents here.
12240 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
12241 instead of returning ID immediately, since we need to search for
12242 a subsequent colon.
12243 (<INITIAL>"'", "\""): Save token_start.
12244 (<INITIAL>"%{", "{", "%%"): Save code_start.
12245 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
12246 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
12247 BEGIN context_state at end, not INITIAL.
12248 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
12249 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
12250 Return correct token start.
12251 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
12252 the start of a character, string or multiline comment is found.
12253 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
12254 Reduction): Adjust reported locations to match the more-precise
12255 results now expected.
12256 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
12257 * tests/reduce.at (Useless Rules, Reduced Automaton,
12258 Underivable Rules): Likewise.
12259 * tests/regression.at (Invalid inputs): No longer `expecting ";"
12260 or "|"' now that so many other tokens are allowed by the new grammar.
12262 * src/complain.h (current_file): Remove duplicate decl;
12263 current_file is now owned by files.h.
12264 * src/complain.c, src/scan-gram.l: Include files.h.
12266 2002-12-06 Paul Eggert <eggert@twinsun.com>
12268 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
12269 promotes to int; it might be unsigned int.
12270 * data/yacc.c (yy_reduce_print): Likewise.
12272 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
12273 be #defined in the prologue, not in the Bison declarations.
12274 This fixes Debian Bug 102878, reported by Shaul Karl.
12276 2002-12-02 Paul Eggert <eggert@twinsun.com>
12278 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
12279 * lib/strtoul.c: New file, from gnulib.
12280 This fixes a porting bug reported by Peter Klein in
12281 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
12283 2002-11-30 Paul Eggert <eggert@twinsun.com>
12285 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
12286 and put only a forward declaration in the prologue. This is for
12287 consistency with the other scanner helper functions.
12289 Type clashes now generate warnings, not errors, since it
12290 appears that POSIX may allow some grammars with type clashes.
12291 * src/reader.c (grammar_current_rule_check): Warn about
12292 type clashes instead of complaining.
12293 * tests/input.at (Type Clashes): Expect warnings, not complaints.
12295 Add Yacc library, since POSIX requires it.
12296 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
12297 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
12298 * lib/main.c, lib/yyerror.c: New files.
12300 gram_error can be static; it need not be extern.
12301 * src/reader.h (gram_error): Remove decl.
12302 * src/parse-gram.y (gram_error): Now static. Add static decl.
12303 (print_token_value): Omit parameter names from forward decl,
12306 2002-11-29 Paul Eggert <eggert@twinsun.com>
12308 * doc/bison.texinfo: Emphasize that yylex and yyerror must
12309 be declared before being used. E.g., one should typically
12310 declare them in the prologue. Use GNU coding style in examples.
12311 Put "const" consistently after the type it modifies. Mention
12312 that C99 supports "inline". Mention that yyerror traditionally
12315 %parse-param and %lex-param now take just one argument, the
12316 declaration; the argument name is deduced from the declaration.
12318 * doc/bison.texinfo (Parser Function, Pure Calling, Error
12319 Reporting, Table of Symbols): Document this.
12320 * src/parse-gram.y (add_param): New function.
12322 (declaration): Implement new rule for %parse-param and %lex-param.
12323 * src/scan-gram.l: "," now elicits a warning, rather than being
12324 a token; this is more compatible with byacc.
12325 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
12327 2002-11-27 Paul Eggert <eggert@twinsun.com>
12329 Rename identifiers to avoid real and potential collisions.
12331 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
12332 to avoid collision with lex macro described by Bruce Lilly in
12333 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
12334 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
12335 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
12336 * src/parse-gram.y (print_token_value): Renamed from yyprint.
12338 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
12339 The name "yycontrol" violates the name space rules, and this stuff
12340 wasn't being used anyway.
12341 (input): Remove action; this stuff wasn't being used.
12342 (gram_error): Rename local variable yylloc -> loc.
12343 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
12344 (YY_DECL): Don't use "yy" at start of local variables.
12345 All uses changed, e.g., yylloc -> loc.
12346 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
12347 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
12348 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
12349 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
12351 * src/parse-gram.y (gram_error): loc is now const *.
12352 * src/reader.h (gram_error): Likewise.
12354 2002-11-24 Paul Eggert <eggert@twinsun.com>
12358 * tests/actions.at (Actions after errors): Use an output format
12359 more similar to that of the Printers and Destructors test.
12360 Test the position of the ';' token too.
12361 (Printers and Destructors): Likewise.
12362 (Printers and Destructors: %glr-parser): Remove for now, to avoid
12363 unnecessarily alarming people when the test fails.
12365 * data/yacc.c (yyerrlab1): Move this label down, so that the
12366 parser does not discard the lookahead token if the user code
12367 invokes YYERROR. This change is required for POSIX conformance.
12369 * lib/error.c: Sync with gnulib.
12371 2002-11-22 Paul Eggert <eggert@twinsun.com>
12373 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
12374 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
12375 * lib/xmalloc.c: Likewise.
12377 2002-11-20 Paul Eggert <eggert@twinsun.com>
12379 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
12381 2002-11-20 Paul Eggert <eggert@twinsun.com>
12383 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
12384 should use `if (! x) abort ();' rather than `assert (x);', and
12385 anyway it's one less thing to worry about configuring.
12387 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
12388 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
12389 and replace all instances of assert with abort.
12390 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
12391 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
12393 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
12394 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
12395 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
12396 hash_find_entry, hash_rehash, hash_insert): Likewise.
12397 * src/conflicts.c (resolve_sr_conflict): Likewise.
12398 * src/lalr.c (set_goto_map, map_goto): Likewise.
12399 * src/nullable.c (nullable_compute): Likewise.
12400 * src/output.c (prepare_rules, token_definitions_output): Likewise.
12401 * src/reader.c (packgram, reader): Likewise.
12402 * src/state.c (state_new, state_free, state_transitions_set,
12403 state_reduction_find): Likewise.
12404 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
12405 symbol_pack): Likewise.
12406 * src/tables.c (conflict_row, pack_vector): Likewise.
12407 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
12408 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
12409 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
12410 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
12412 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
12413 (ARGMATCH_CONSTRAINT): New macro.
12414 (ARGMATCH_ASSERT): Use it.
12416 * src/system.h (verify): New macro.
12417 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
12418 rather than assert.
12419 * src/tables.c (tables_generate): Likewise.
12421 * src/struniq.c (struniq_assert): Now returns void, and aborts
12422 if the assertion is false.
12423 (struniq_assert_p): Remove.
12424 * src/struniq.h: Likewise.
12426 2002-11-18 Paul Eggert <eggert@twinsun.com>
12428 * data/glr.c (yygetLRActions): Replace `yyindex' with
12429 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
12430 This fixes the regression with Sun ONE Studio 7 cc that I reported in
12431 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
12433 2002-11-18 Akim Demaille <akim@epita.fr>
12435 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
12437 From Tim Van Holder.
12439 2002-11-17 Paul Eggert <eggert@twinsun.com>
12441 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
12442 to "SyntaxError" for consistency with my 2002-11-15 change.
12444 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
12445 not define to {}, since this breaks the common use of `YYDPRINTF
12446 ((...));' if a single statement is desired (e.g. before `else').
12447 Work around GCC warnings by surrounding corresponding calls with
12449 (yyhasResolvedValue): Remove unused function.
12450 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
12452 (yyreportSyntaxError): Renamed from yyreportParseError.
12453 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
12455 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
12456 extern when possible. Remove unused initializations.
12458 2002-11-16 Akim Demaille <akim@epita.fr>
12460 Augment the similarity between GLR and LALR traces.
12462 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
12463 (YY_REDUCE_PRINT): New.
12464 (yyparse): Use them.
12465 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
12467 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
12468 state reached after the reduction/recovery, since...
12469 (yyparse, yyprocessOneStack): Report the state we are entering in.
12471 2002-11-16 Akim Demaille <akim@epita.fr>
12473 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
12474 Add support for --trace=skeleton.
12475 * src/scan-skel.l: %option debug.
12476 Scan strings of non-@ or \n instead of character by character.
12477 (scan_skel): Handle trace_skeleton.
12479 (@output_parser_name@, @output_header_name@): ``Restore'' their
12480 support (used to be M4 macros).
12481 * data/yacc.c: Quote larger chunks, a la glr.c.
12482 * data/lalr1.cc: Likewise.
12483 The header guards are no longer available, so use some other
12484 string than `YYLSP_NEEDED'.
12486 2002-11-16 Akim Demaille <akim@epita.fr>
12488 Make the ``Printers and Destructors'' test more verbose, taking
12489 `yacc.c''s behavior as (possibly wrong) reference.
12491 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
12492 instead of fprint on stdout.
12493 Set and report the last_line of the symbols.
12494 Consistently display values and locations.
12496 2002-11-16 Paul Eggert <eggert@twinsun.com>
12498 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
12500 2002-11-15 Paul Eggert <eggert@twinsun.com>
12502 * tests/actions.at (Actions after errors): New test case.
12504 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
12505 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
12506 tests/action.at, tests/calc.at, tests/conflicts.at,
12507 tests/cxx-type.at, tests/regression.at:
12508 "parse error" -> "syntax error" for POSIX compatibility.
12509 "parsing stack overflow..." -> "parser stack overflow" so
12510 that code matches Bison documentation.
12512 2002-11-15 Akim Demaille <akim@epita.fr>
12514 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
12515 take two BRACED_CODE, not two string_content.
12516 Free the scanner's obstack when we are done.
12517 (code_content): New.
12518 * tests/calc.at: Adjust.
12519 * doc/bison.texinfo: Adjust.
12520 Also, make sure to include the `,' for these declarations.
12522 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
12524 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
12525 definition; avoids potential autoreconf problems.
12527 2002-11-15 Akim Demaille <akim@epita.fr>
12529 Always check the value returned by yyparse.
12531 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
12532 returned by yyparse.
12533 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
12535 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
12536 returned by yyparse.
12538 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12540 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
12543 2002-11-14 Paul Eggert <eggert@twinsun.com>
12545 * src/output.c (output_skeleton): Call xfopen instead of
12546 duplicating xfopen's body.
12548 Fix bugs reported by Nelson H. F. Beebe in
12549 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
12551 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
12552 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
12553 Group compiler. Instead, use "$CC -E bar.c". Include the .h
12554 file twice in the grammar, as an extra check.
12556 * tests/input.at (Torturing the Scanner): Surround the
12557 backslash-newline tests with "#if 0", to make it less likely that
12558 we'll run into compiler bugs. Bring back solitary \ inside
12559 comment, but add a closing comment to work around HP C bug. Don't
12560 test backslash-newline in C character constant.
12562 2002-11-14 Akim Demaille <akim@epita.fr>
12564 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
12565 status of the compiler.
12566 Calling `exit 1' is no longer needed.
12567 Reported by Nelson H. F. Beebe.
12569 2002-11-14 Akim Demaille <akim@epita.fr>
12571 * tests/atlocal.in (CPPFLAGS): We have config.h.
12572 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
12574 * tests/actions.at, tests/calc.at, tests/conflicts.at,
12575 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
12576 * tests/regression.at, tests/torture.at: Use them for all the
12577 grammars that are to be compiled.
12578 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
12579 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
12580 * doc/bison.texinfo (GLR Parsers): Document `inline'.
12582 2002-11-14 Akim Demaille <akim@epita.fr>
12584 * doc/bison.texinfo: Various formatting changes (alignments in
12585 samples, additional @group/@end group, GCS in samples.
12586 Use @deffn instead of simple @table to define the directives,
12587 macros, variables etc.
12589 2002-11-13 Paul Eggert <eggert@twinsun.com>
12591 Fix some bugs reported by Albert Chin-A-Young in
12592 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
12594 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
12595 -o c"; the HP C compiler chatters during compilation.
12596 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
12597 * tests/headers.at (export YYLTYPE): Likewise.
12599 * tests/input.at (Torturing the Scanner): Remove lines containing
12600 solitary backslashes, as they tickle a bug in the HP C compiler.
12602 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
12603 comments, since they're not portable. Use GNU coding style.
12605 2002-11-13 Akim Demaille <akim@epita.fr>
12607 * data/yacc.c: Leave bigger chunks of quoted text.
12608 (YYDSYMPRINTF): New.
12609 Use it to report symbol activities.
12610 * data/glr.c (YYDSYMPRINTF): New.
12613 2002-11-12 Paul Eggert <eggert@twinsun.com>
12617 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
12618 (yyglrReduce): Return yyok, not 0.
12619 This should avoid the enumerated-type warnings reported
12620 by Nelson H. F. Beebe in
12621 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
12623 * lib/bbitset.h (BITSET_INLINE): Remove.
12624 * lib/bitset.h [! BITSET_INLINE]: Remove.
12625 (bitset_set, bitset_reset, bitset_test): Rename local vars
12626 to avoid shadowing warnings by GCC.
12628 * data/glr.c (inline): Remove #define. It's the user's
12629 responsibility to #define it away, just like 'const'.
12630 This fixes one of the bugs reported by Nelson H. F. Beebe in
12631 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
12633 * Makefile.maint (po-check): Scan .l and .y files instead of the
12634 .c and the .h files that they generate. This fixes the bug
12635 reported by Tim Van Holder in:
12636 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
12637 Look for N_ as well as for _. Try to avoid matching #define for
12639 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
12640 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
12641 * src/scan-gram.l: Revamp regular expressions so that " and '
12642 do not confuse xgettext.
12644 * src/struniq.h (struniq_new): Do not declare the return type
12645 to be 'const'; this violates the C standard.
12646 * src/struniq.c (struniq_new): Likewise.
12648 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
12650 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
12651 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
12654 2002-11-12 Akim Demaille <akim@epita.fr>
12656 * Makefile.maint: Sync with Autoconf:
12657 (local_updates): New.
12659 2002-11-12 Akim Demaille <akim@epita.fr>
12661 * po/POTFILES.in (src/lalr.c, src/state.c): Remove
12663 2002-11-12 Akim Demaille <akim@epita.fr>
12665 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the
12668 2002-11-12 Akim Demaille <akim@epita.fr>
12670 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
12673 2002-11-12 Akim Demaille <akim@epita.fr>
12675 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
12676 Use it to test the GLR parser.
12678 2002-11-12 Akim Demaille <akim@epita.fr>
12680 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
12682 * data/glr.c (yystos): New.
12683 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
12684 (YYDSYMPRINT): New.
12685 (yyval): Don't define it, it is handled via M4.
12686 (yyrecoverParseError): Free verbosely the discarded symbols.
12687 * data/yacc.c (yysymprint): Remove, rather...
12688 (b4_yysymprint_generate): invoke.
12689 * data/c.m4 (b4_yysymprint_generate): New.
12690 Accept pointers as arguments, as opposed to the version from
12692 (b4_yydestruct_generate): Likewise.
12693 * tests/cations.at (Printers and Destructors): Use Bison directives
12694 instead of CPP macros.
12695 Don't rely on internal details.
12697 2002-11-12 Akim Demaille <akim@epita.fr>
12699 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
12700 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
12701 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
12702 it against YYEMPTY and so forth), work on yytoken (i.e., set
12703 it to YYEMPTY etc.).
12704 (yydestruct): Replace with a b4_yydestruct_generate invocation.
12705 (b4_symbol_actions): Remove.
12706 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
12707 for 0, end-of-input.
12709 2002-11-12 Akim Demaille <akim@epita.fr>
12711 * doc/bison.texinfo (Destructor Decl): New.
12713 2002-11-12 Akim Demaille <akim@epita.fr>
12715 * src/tables.c (tables_generate): Use free for pointers that
12716 cannot be NULL, not XFREE.
12717 (pack_vector): Use assert, not fatal, for bound violations.
12718 * src/state.c (state_new): Likewise.
12719 * src/reader.c (reader): Likewise.
12720 * src/lalr.c (set_goto_map): Likewise.
12721 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
12724 2002-11-12 Akim Demaille <akim@epita.fr>
12726 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
12728 * src/scan-gram.l (last_string): Is global to the file, not to
12730 * src/parse-gram.y (input): Don't append the epilogue here,
12731 (epilogue.opt): do it here, and free the scanner's obstack.
12732 * src/reader.c (epilogue_set): Rename as...
12733 (epilogue_augment): this.
12734 * data/c.m4 (b4_epilogue): Defaults to empty.
12736 2002-11-12 Akim Demaille <akim@epita.fr>
12738 * src/getargs.c (long_options): Remove duplicates.
12739 * src/vmsgetargs.c, src/build.com, src/bison.cld, src/vmshlp.mar:
12741 * doc/bison.rnh: Remove.
12742 * doc/bison.texinfo (VMS Invocation): Remove.
12744 2002-11-12 Akim Demaille <akim@epita.fr>
12746 * src/struniq.h, src/struniq.c (struniq_t): Is const.
12747 (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New.
12749 Use struniq for symbols.
12751 * src/symtab.h (symbol_t): The tag member is a struniq.
12752 (symbol_type_set): Adjust.
12753 * src/symtab.c (symbol_new): Takes a struniq.
12754 (symbol_free): Don't free the tag member.
12755 (hash_compare_symbol_t, hash_symbol_t): Rename as...
12756 (hash_compare_symbol, hash_symbol): these.
12757 Use the fact that tags as struniqs.
12758 (symbol_get): Use struniq_new.
12759 * src/symlist.h, src/symlist.c (symbol_list_n_type_name_get):
12761 * src/reader.h (merger_list, grammar_currentmerge_set): The name
12762 and type members are struniqs.
12763 * src/reader.c (get_merge_function)
12764 (grammar_current_rule_merge_set): Adjust.
12765 (TYPE, current_type): Are struniq.
12767 Use struniq for file names.
12769 * src/files.h, src/files.c (infile): Split into...
12770 (grammar_file, current_file): these.
12771 * src/scan-gram.c (YY_USER_INIT, handle_syncline): Adjust.

12775 * src/main.c (main): Call struniqs_new early enough to use it for
12777 Don't free the input file name.
12779 2002-11-12 Akim Demaille <akim@epita.fr>
12781 * src/symtab.c (symbol_free): Remove dead deactivated code:

12792 2002-11-11 Paul Eggert <eggert@twinsun.com>
12794 Revamp to fix many (but not all) of the C- and M4-related quoting
12795 problems. Among other things, this fixes the Bison bug reported
12796 by Jan Hubicka when processing the Bash grammar; see:
12797 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
12799 Use new @ escapes consistently. Represent brackets with @{ and @}
12800 rather than @<:@ and @:>@, since this works a bit better with dumb
12801 editors like vi. Represent @ with @@, since @ is now consistently
12802 an escape. Use @oline@ and @ofile@ rather than __oline__ and
12803 __ofile__, to avoid unexpected expansions. Similarly, use @output
12804 rather than #output.
12806 * data/c.m4 (b4_copyright): Omit file name from comment, since
12807 the file name could contain "*/".
12808 (b4_synclines_flag): Don't quote the 2nd argument; it should already
12809 be quoted. All uses changed.
12811 * data/glr.c: Use new @ escapes consistently.
12812 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
12813 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
12814 Remove, since they couldn't handle arbitrary characters in file
12816 * data/lalr1.cc: Likewise.
12817 * data/yacc.c: Likewise.
12819 * src/files.c (output_infix): Remove; all uses removed.
12820 * src/files.h: Likewise.
12822 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
12823 mishandled funny characters in file names, and anyway it isn't
12825 * data/yacc.c: Likewise.
12826 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
12828 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
12829 * data/yacc.c: Likewise.
12831 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
12833 (muscle_init): Quote filename as a C string.
12834 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
12835 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
12836 * src/output.c (escaped_file_name_output): New function.
12837 (prepare_symbols): Quote tokens for M4.
12838 (prepare): Don't insert output_infix, output_prefix,
12839 output_parser_name, output_header_name; this is now down by scan-skel.
12840 Insert skeleton as a C string.
12842 * src/output.c (user_actions_output, symbol_destructors_output,
12843 symbol_printers_output): Quote filenames for C and M4.
12844 * src/reader.c (prologue_augment, epilogue_set): Likewise.
12846 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
12847 escapes other than \\ and \'; this simplifies the code.
12848 (<SC_STRING>): Likewise, for \\ and \".
12849 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
12850 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
12851 Use new escapes @{ and @} for [ and ].
12853 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
12854 them with auto vars.
12855 Switch to new escape scheme, where @ is the escape character uniformly.
12856 Abort if a stray escape character is found. Avoid unbounded input
12857 buffer when parsing non-escaped text.
12859 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
12860 __oline__, #output, $@, and @{ do not have unintended meanings.
12862 2002-11-09 Paul Eggert <eggert@twinsun.com>
12864 Fix the test failure due to GCC warnings described in
12865 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
12866 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
12867 evaluate to 0 if it's impossible for NINF to be in the respective
12869 (yygetLRActions, yyrecoverParseError): Use them.
12871 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
12872 counted in the token inserted at end of file. Now takes
12873 location_t *, not location_t, so that the location can be
12874 adjusted. All uses changed.
12876 * tests/regression.at (Invalid inputs): Adjust wording in
12877 diagnostic to match the new behavior.
12879 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
12880 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
12881 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
12882 abort ();'. This reduces the runtime of the "Many lookaheads"
12883 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
12886 2002-11-07 Paul Eggert <eggert@twinsun.com>
12888 * src/parse-gram.y (CHARACTER): Remove unused token.
12891 * src/scan-gram.l: Remove stack option. We no longer use the
12892 stack, since the stack was never deeper than 1; instead, use the
12893 new auto var c_context to record the stacked value.
12895 Remove nounput option. At an unexpected end of file, we now unput
12896 the minimal input necessary to end cleanly; this simplifies the
12899 Avoid unbounded token sizes where this is easy.
12901 (unexpected_end_of_file): New function.
12902 Use it to systematize the error message on unexpected EOF.
12903 (last-string): Now auto, not static.

12910 2002-11-07 Akim Demaille <akim@epita.fr>
12912 Let yyerror always receive the msg as last argument, so that
12913 yyerror can be variadic.
12915 * data/yacc.c (b4_yyerror_args): New.
12916 Use it when calling yyerror.
12917 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.

12967 * src/scan-gram.l: Use more accurate diagnostics, e.g.
12968 "integer out of range" rather than "invalid value".
12969 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
12972 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
12973 Also, remove one static variable in the scanner.
12975 * src/scan-gram.l (braces_level): Now auto, not static.
12976 Initialize to zero if the compiler is being picky.
12977 (INITIAL): Clear braces_level instead of incrementing it.
12978 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,

12985 * src/scan-gram.l: When it starts with `%', complain about the
12986 whole directive, not just that `invalid character: %'.
12988 2002-11-04 Akim Demaille <akim@epita.fr>
12990 * Makefile.maint: Update from Autoconf.
12991 (update, cvs-update, po-update, do-po-update): New.

13009 Use quote, not quote_n since LOCATION_PRINT no longer uses the
13012 2002-11-03 Paul Eggert <eggert@twinsun.com>
13014 * src/reader.c (get_merge_function, grammar_current_rule_check):
13015 Use consistent diagnostics for reporting type name clashes.
13016 Quote the types with <>, for consistency with Yacc.
13017 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
13019 2002-11-03 Akim Demaille <akim@epita.fr>
13021 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
13023 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.

13033 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
13034 (yyreportAmbiguity): When using a pure parser, also need
13035 the location, and the parse-params.
13037 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
13038 When using a pure parser, also need the parse-params.
13040 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
13041 (%pure-parser + %parse-param) LALR and GLR parsers.
13042 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
13043 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,

13052 Document %error-verbose, deprecate YYERROR_VERBOSE.
13054 2002-11-03 Akim Demaille <akim@epita.fr>
13056 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
13057 AT_CHECK_CALC_GLR invocations to use % directives, instead of
13058 command line options.
13059 * tests/cxx-type.at: Formatting changes.
13061 2002-11-03 Paul Eggert <eggert@twinsun.com>
13063 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
13064 to count columns correctly, and to check for invalid inputs.
13066 Use mbsnwidth to count columns correctly. Account for tabs, too.
13067 Include mbswidth.h.
13068 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
13069 (extend_location): New function.
13070 (YY_LINES): Remove.
13072 Handle CRLF in C code rather than in Lex code.

13081 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
13083 (tag, splice): New EREs. Do not allow NUL or newline in tags.
13084 Use {splice} wherever C allows backslash-newline.
13085 YY_STEP after space, newline, vertical-tab.
13086 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
13088 (letter, id): Don't assume ASCII; e.g., spell out a-z.
13090 ({int}, handle_action_dollar, handle_action_at): Check for integer
13093 (YY_STEP): Omit trailing semicolon, so that it's more like C.
13095 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
13096 as well as \000. Check for UCHAR_MAX, not 255.
13097 Allow \x with an arbitrary positive number of digits, as in C.
13098 Check for overflow here.
13099 Allow \? and UCNs, for compatibility with C.
13101 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
13102 with quote slot used by complain_at.
13104 * tests/input.at: Add tests for backslash-newline, m4 quotes
13105 in symbols, long literals, and funny escapes in strings.
13107 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
13108 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.

13111 * m4/mbswidth.m4: New file, from GNU coreutils.
13113 * doc/bison.texinfo (Grammar Outline): Document // comments.
13114 (Symbols): Document that trigraphs have no special meaning in Bison,
13115 nor is backslash-newline allowed.

13121 2002-11-02 Paul Eggert <eggert@twinsun.com>
13123 * src/reader.c: Don't include quote.h; not needed.
13124 (get_merge_function): Reword warning to be consistent with
13125 type clash diagnostic in grammar_current_rule_check.
13127 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
13128 bug in trigraph handling.
13130 * src/output.c (prepare_symbols): When printing token names,
13131 escape "[" as "@<:@" and likewise for "]".
13133 * src/system.h (errno): Remove declaration, as we are now
13134 assuming C89 or better, and C89 guarantees errno.
13136 2002-10-30 Paul Eggert <eggert@twinsun.com>
13138 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
13139 Check for close failures.
13140 * src/files.h (xfclose): Return void, not int, since it always
13142 * src/files.c (xfclose): Likewise. Report I/O error if ferror
13144 * src/output.c (output_skeleton): Use xfclose rather than fclose
13145 and ferror. xfclose now checks ferror.
13147 * data/glr.c (YYLEFTMOST_STATE): Remove.
13148 (yyreportTree): Use a stack-based leftmost state. This avoids
13149 our continuing battles with bogus warnings about initializers.
13151 2002-10-30 Akim Demaille <akim@epita.fr>
13153 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only

13166 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
13167 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
13168 we use malloc. Don't assume 'A' through 'Z' are contiguous.
13169 Don't assume strdup exists; POSIX says its an XSI extension.
13170 Check for buffer overflow on input.
13172 2002-10-24 Akim Demaille <akim@epita.fr>
13174 * src/output.c (output_skeleton): Don't disable M4sugar comments
13175 too soon: it results in comments being expanded.
13176 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
13179 2002-10-24 Akim Demaille <akim@epita.fr>
13181 * data/yacc.c (m4_int_type): New.
13182 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
13183 char' as only yacc.c wants K&R portability.
13184 * data/glr.c (yysigned_char): Remove.
13185 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
13186 Reported by Quoc Peyrot.
13188 2002-10-23 Paul Eggert <eggert@twinsun.com>
13190 * src/main.c (main): With --trace=time, report times even if a
13191 non-fatal error occurs. Formerly, the times were reported in some
13192 such cases but not in others.
13193 * src/reader.c (reader): Just return if a complaint has been issued,
13194 instead of exiting, so that 'main' can report times.
13196 2002-10-22 Akim Demaille <akim@epita.fr>
13198 * src/system.h: Include sys/types.
13199 Reported by Bert Deknuydt.
13201 2002-10-23 Paul Eggert <eggert@twinsun.com>
13203 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.

13206 2002-10-22 Paul Eggert <eggert@twinsun.com>
13208 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
13209 decl; not needed any more.
13210 * src/main.c (main): Use return to exit, undoing yesterday's change.
13211 The last OS that we could find where this wouldn't work is
13212 SunOS 3.5, and that's too old to worry about now.
13214 * data/glr.c (struct yyltype): Define members even when not
13215 doing locations. This is more consistent with yacc.c, and it
13216 works around the following bug reports:
13217 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
13218 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
13220 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
13221 @acronym consistently. Standardize on "Yacc" instead of "YACC",
13222 "Algol" instead of "ALGOL". Give a bit more history about BNF.
13224 2002-10-22 Akim Demaille <akim@epita.fr>
13226 * data/README: New.
13228 2002-10-21 Paul Eggert <eggert@twinsun.com>
13230 Be consistent about 'bool'; the old code used an enum in one
13231 module and an int in another, and this violates the C standard.
13232 * m4/stdbool.m4: New file, from coreutils 4.5.3.
13233 * configure.ac (AC_HEADER_STDBOOL): Add.
13234 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
13235 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
13236 * src/symtab.c (hash_compare_symbol_t): Likewise.
13237 * src/system.h (bool, false, true): Use a definition consistent
13238 with ../lib/hash.c. All uses changed.
13240 * src/complain.c (warning_issued): Renamed from warn_message_count,
13241 so that we needn't worry about integer overflow (!).
13242 Now of type bool. All uses changed.
13243 (complaint_issued): Renamed from complain_message_count; likewise.
13245 * src/main.c (main): Use exit to exit with failure.
13247 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
13248 rather than 1 and 0.
13249 * src/main.c (main): Likewise.
13250 * src/getargs.c (getargs): Likewise.
13251 * src/reader.c (reader): Likewise.
13253 * src/getarg.c (getargs): Remove duplicate code for
13254 "Try `bison --help'".
13256 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
13257 What was that "2" for?
13259 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
13260 * src/getargs.c (usage): Likewise.
13262 * src/getargs.c (getargs): When there are too few operands, report
13263 the last one. When there are too many, report the first extra
13264 one. This is how diffutils does it.
13266 2002-10-20 Paul Eggert <eggert@twinsun.com>
13268 Remove K&R vestiges.
13269 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
13270 * src/complain.c (VA_START): Remove. Assume prototypes.
13271 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
13272 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
13273 fatal): Assume prototypes.
13274 * src/complain.h: Assume prototypes.
13275 * src/system.h (PARAMS): Remove.
13276 Include <limits.h> unconditionally, since it's guaranteeed even
13277 for a freestanding C89 compiler.
13278 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
13279 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
13281 2002-10-20 Akim Demaille <akim@epita.fr>
13283 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
13284 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.

13288 (yy_reduce_print): New.

13294 arguments and output `void'.

13297 (b4_c_function_decl, b4_c_ansi_function_def)
13298 (b4_c_ansi_function_decl): New.
13299 Change the interpretation of the arguments: before `int, foo', now
13301 * data/yacc.c (yyparse): Prototype and define thanks to these.
13302 Adjust b4_c_function_def uses.
13303 * data/glr.c (yyparse): Likewise, but ANSI only.
13305 2002-10-20 Akim Demaille <akim@epita.fr>
13307 * src/output.c (prepare): Move the definition of `tokens_number',
13308 `nterms_number', `undef_token_number', `user_token_number_max'
13310 (prepare_tokens): Here.
13311 (prepare_tokens): Rename as...
13312 (prepare_symbols): this.
13313 (prepare): Move the definition of `rules_number' to...
13314 (prepare_rules): here.
13315 (prepare): Move the definition of `last', `final_state_number',

13320 2002-10-20 Akim Demaille <akim@epita.fr>
13322 * src/tables.h, src/tables.c, src/output.c: Comment changes.
13324 2002-10-20 Akim Demaille <akim@epita.fr>
13326 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
13329 2002-10-20 Akim Demaille <akim@epita.fr>
13331 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
13332 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
13334 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
13336 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
13337 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
13340 2002-10-19 Paul Eggert <eggert@twinsun.com>
13342 Do not create a temporary file, as that involves security and
13343 cleanup headaches. Instead, use a pair of pipes.
13344 Derived from a suggestion by Florian Krohm.
13345 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
13346 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.

13356 (output_skeleton): Use pipe rather than temporary file for m4 input.
13357 Check that m4sugar.m4 is readable, to avoid deadlock.
13358 Check for pipe I/O error.
13359 * src/scan-skel.l (readpipe): Remove decl.
13360 (scan_skel): New function, to be used in place of m4_invoke.
13361 Read from stream rather than file.
13363 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
13364 float, as this generates a warning on Solaris 8 + GCC 3.2 with
13365 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
13366 this generates a more-accurate value anyway.
13368 * lib/timevar.c (timervar_accumulate): Rename locals to
13369 avoid confusion with similarly-named more-global.
13370 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
13372 * src/output.c (prepare): Use xstrdup to convert char const *
13373 to char *, to avoid GCC warning.
13375 2002-10-19 Akim Demaille <akim@epita.fr>
13377 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
13378 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
13379 Use them to have `calc.y' ready for %pure-parser.
13380 * data/yacc.c (YYLEX): Pass a yylex return type to
13381 b4_c_function_call.
13383 2002-10-19 Akim Demaille <akim@epita.fr>
13385 Prototype support of %lex-param and %parse-param.
13387 * src/parse-gram.y: Add the definition of the %lex-param and
13388 %parse-param tokens, plus their rules.
13389 Drop the `_' version of %glr-parser.
13391 * src/scan-gram.l (INITIAL): Scan them.
13392 * src/muscle_tab.c: Comment changes.
13393 (muscle_insert, muscle_find): Rename `pair' as `probe'.
13394 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
13395 (muscle_entry_s): The `value' member is no longer const.
13396 Adjust all dependencies.
13397 * src/muscle_tab.c (muscle_init): Adjust: use
13398 MUSCLE_INSERT_STRING.
13399 Initialize the obstack earlier.
13400 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
13401 (muscle_pair_list_grow): New.
13402 * data/c.m4 (b4_c_function_call, b4_c_args): New.
13403 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
13404 * tests/calc.at: Use %locations, not --locations.
13405 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
13407 2002-10-19 Akim Demaille <akim@epita.fr>
13409 * src/getargs.c (usage): Take status as argument and exit
13411 Report the traditional `Try ... --help' message when status != 0.
13412 (usage, version): Don't take a FILE * as arg, it is pointless.
13413 (getargs): When there is an incorrect number of arguments, make it
13414 an error, and report it GNUlically thanks to `usage ()'.
13416 2002-10-18 Paul Eggert <eggert@twinsun.com>
13418 * data/glr.c (yyreportParseError): Don't assume that sprintf
13419 yields the length of the printed string, as this is not true
13420 on SunOS 4.1.4. Reported by Peter Klein.
13422 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
13423 * tests/conflicts.at (%nonassoc and eof): Likewise.
13424 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
13426 2002-10-17 Akim Demaille <akim@epita.fr>
13428 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
13429 * src/getargs.c (trace_types, trace_args): Adjust.
13430 * src/reader.c (grammar_current_rule_prec_set)
13431 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
13432 Standardize error messages.
13433 And s/@prec/%prec/!
13434 (reader): Use trace_flag to enable scanner/parser debugging,
13435 instead of an adhoc scheme.
13436 * src/scan-gram.l: Remove trailing debugging code.
13438 2002-10-16 Paul Eggert <eggert@twinsun.com>
13440 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
13443 * NEWS: Officially drop support for building Bison with K&R C,
13444 since it didn't work anyway and it's not worth worrying about.
13445 * Makefile.maint (wget_files): Remove ansi2knr.c.
13446 (ansi2knr.c-url_prefix): Remove.
13447 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
13448 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
13449 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
13451 2002-10-15 Paul Eggert <eggert@twinsun.com>
13453 Stop using the "enum_" trick for K&R-style function definitions;
13454 it confused me, and I was the author! Instead, assume that people
13455 who want to use K&R C compilers (when using these modules in GCC,
13456 perhaps?) will run ansi2knr.
13458 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
13459 All uses of "enum_" changed to "enum ".
13460 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
13461 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
13463 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

13471 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
13472 Use function prototypes; this removes the need for declaring
13473 static functions simply to provide their prototypes.
13474 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

13533 * tests/Makefile.am (maintainer-check-posix): New.
13535 2002-10-14 Akim Demaille <akim@epita.fr>
13537 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
13540 2002-10-14 Akim Demaille <akim@epita.fr>
13542 * src/tables.c (table_ninf_remap): base -> tab.
13543 Reported by Matt Rosing.
13545 2002-10-14 Paul Eggert <eggert@twinsun.com>
13547 * tests/action.at, tests/calc.at, tests/conflicts.at,
13548 tests/cxx-type.at, tests/headers.at, tests/input.at,
13549 tests/regression.at, tests/synclines.at, tests/torture.at:
13550 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
13551 so that the tests still work even if POSIXLY_CORRECT is set.
13552 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
13554 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
13555 for portability to K&R hosts. Fix typo: signed char is guaranteed
13556 only to 127, not to 128.
13557 * data/glr.c (yysigned_char): New type.
13558 * data/yacc.c (yysigned_char): Likewise.
13559 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
13561 2002-10-13 Paul Eggert <eggert@twinsun.com>
13563 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
13564 true due to limited range of data type" warning from GCC.
13566 * data/c.m4 (b4_token_defines): Protect against double-inclusion
13567 by wrapping enum yytokentype's definition inside #ifndef
13568 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
13570 2002-10-13 Akim Demaille <akim@epita.fr>
13572 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
13573 Un yy- yyrhs to avoid the name clash with the global YYRHS.
13575 2002-10-13 Akim Demaille <akim@epita.fr>
13577 * Makefile.maint: Update from Autoconf 2.54.
13578 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
13580 2002-10-13 Akim Demaille <akim@epita.fr>
13582 * src/print.c (print_state): Separate the list of solved conflicts
13583 from the other items.
13584 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
13586 2002-10-13 Akim Demaille <akim@epita.fr>
13588 Let nondeterministic skeletons be usable with deterministic
13591 With the patch, GAWK compiled by GCC without -O2 passes its test
13592 suite using a GLR parser driven by LALR tables. It fails with -O2
13593 because `struct stat' gives two different answers on my machine:
13594 88 (definition of an auto var) and later 96 (memset on this var).
13595 Hence the stack is badly corrumpted. The headers inclusion is to
13596 blame: if I move the awk.h inclusion before GLR's system header
13597 inclusion, the two struct stat have the same size.
13599 * src/tables.c (pack_table): Always create conflict_table.
13600 (token_actions): Always create conflict_list.
13601 * data/glr.c (YYFLAG): Remove, unused.
13603 2002-10-13 Akim Demaille <akim@epita.fr>
13605 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
13607 (VALGRIND, GXX): New.
13608 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
13609 * tests/bison.in: Run $PREBISON a pre-command.
13610 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
13611 (maintainer-check-g++): New.
13612 * Makefile.am (maintainer-check): New.
13614 2002-10-13 Akim Demaille <akim@epita.fr>
13616 * data/glr.c: Formatting changes.
13617 Tweak some trace messages to match yacc.c's.
13619 2002-10-13 Akim Demaille <akim@epita.fr>
13621 GLR parsers sometimes raise parse errors instead of performing the
13623 Reported by Charles-Henry de Boysson.
13625 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
13626 check the length of the traces when %glr.
13627 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
13629 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
13631 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
13632 (yyltype): Remove the yy prefix from the member names.
13633 (yytable): Complete its comment.
13634 (yygetLRActions): Map error action number from YYTABLE from
13636 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
13637 (which was a bug: it should have been YYTABEL_NINF, and yet it was
13638 not satisfying as we could compare an YYACTION computed from
13639 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
13640 only value for error actions.
13641 (yyreportParseError): In verbose parse error messages, don't issue
13642 `error' in the list of expected tokens.
13643 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
13644 next action to perform to match glr.c's decoding.
13645 (yytable): Complete its comment.
13647 2002-10-13 Paul Eggert <eggert@twinsun.com>
13649 Fix problem reported by Henrik Grubbstroem in
13650 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
13651 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
13652 because the Bison parser reads the second action before reducing
13654 * src/scan-gram.l (rule_length): New static var.
13655 Use it to keep track of the rule length in the scanner, since
13656 we can't expect the parser to be in lock-step sync with the scanner.
13657 (handle_action_dollar, handle_action_at): Use this var.
13658 * tests/actions.at (Exotic Dollars): Test for the problem.
13660 2002-10-12 Paul Eggert <eggert@twinsun.com>
13662 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
13663 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
13664 Include <sys/time.h> when checking for clock_t and struct tms.
13665 Use same include order as source.
13666 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
13667 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
13669 * lib/timevar.c: Update copyright date and clarify comments.
13670 (get_time) [IN_GCC]: Keep the GCC version for reference.
13672 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
13673 GCC version as of today, then merge Bison's changes.
13674 Change "GCC" to "Bison" in copyright notice. timevar.def's
13675 author is Akim, so change that too.
13677 * src/reader.c (grammar_current_rule_check):
13678 Don't worry about the default action if $$ is untyped.
13679 Prevents bogus warnings reported by Jim Gifford in
13680 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
13682 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
13683 * data/glr.c, data/lalr1.cc, data/yacc.c:
13684 Output token definitions before the first part of user declarations.
13685 Fixes compatibility problem reported by Jim Gifford for kbd in
13686 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
13688 2002-10-11 Paul Eggert <eggert@twinsun.com>
13690 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
13691 (yyparse): here. This undoes some of the 2002-07-25 change.
13692 Compatibility problem reported by Ralf S. Engelschall with
13693 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.

13712 * lib/lbitset.c: Likewise.
13714 * lib/abitset.c (abitset_bytes): Return a size that is aligned

13717 properly aligned for the whole union.

13757 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
13758 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
13760 Do not use "struct bitset_struct" to mean different things in
13761 different modules. Not only is this confusing, it violates
13762 the C Standard, which requires that structure types in different
13763 modules must be compatible if one is to be passed to the other.
13764 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
13765 All instances of "struct bitset_struct *" replaced with "bitset".
13766 * lib/bitset.h (struct bitset_struct): Remove, replacing with....

13776 bitset_struct): Remove.
13777 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
13780 Do not call a function of type T using a call that assumes the
13781 function is of a different type U. Standard C requires that a
13782 function must be called with a type that is compatible with its
13784 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
13786 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
13788 * lib/ebitset.c (PFV): Remove.

13805 Use offsetof, for simplicity.
13807 2002-10-06 Paul Eggert <eggert@twinsun.com>
13809 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
13810 the same width as int. This reapplies a hunk of the 2002-08-12 patch
13811 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
13812 which was inadvertently undone by the 2002-09-30 patch.
13813 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
13814 the same width as int.
13816 2002-10-04 Paul Eggert <eggert@twinsun.com>

13840 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
13841 POSIX 1003.1-2001 has removed fgrep.

13918 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
13919 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

14166 to void, to avoid a GCC warning when --disable-nls is in effect.
14168 * src/scan-gram.l: Use strings rather than escapes when possible,
14169 to minimize the number of warnings from xgettext.
14170 (handle_action_dollar, handle_action_at): Don't use isdigit,
14171 as it mishandles negative chars and it may not work as expected
14172 outside the C locale.
14174 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
14175 this is a GCC extension and is not portable to other compilers.

14189 exit status as failure, not just exit status 1. Sun C exits

14195 2002-08-02 Akim Demaille <akim@epita.fr>
14197 * src/conflicts.c (conflicts_output): Don't output rules never
14198 reduced here, since anyway that computation doesn't work.

14414 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
14415 for the time being: %locations ought to provide it to yyerror.

16392 2002-04-07 Akim Demaille <akim@epita.fr>
16394 * data/bison.c++, data/bison.simple: Don't output the current file
16395 name in #line, to avoid useless diffs between two identical
16396 outputs under different names.

16400 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

16617 2002-03-04 Akim Demaille <akim@epita.fr>
16619 * src/closure.c (firsts): Now, also a bitset.
16620 Adjust all dependencies.
16621 (varsetsize): Remove, now unused.
16622 * src/warshall.h, src/warshall.c: Now work on arrays of bitsets.
16624 2002-03-04 Akim Demaille <akim@epita.fr>
16626 * src/print.c: Convert to use bitset.h, not hand coded iterations
16629 2002-03-04 Akim Demaille <akim@epita.fr>
16631 * src/reduce.c: Convert to use bitset.h, not hand coded BSet.
16633 2002-03-04 Akim Demaille <akim@epita.fr>
16635 * src/closure.c (ruleset): Be a bitset.
16636 (rulesetsize): Remove.
16638 2002-03-04 Akim Demaille <akim@epita.fr>
16640 * lib/bitset-int.h, lib/bitset.c, lib/bitset.h, lib/bitsetv.c,

16642 * lib/lbitset.h, lib/sbitset.c, lib/sbitset.h: New.
16643 * src/closure.c (fderives): Be an array of bitsets.
16645 2002-02-28 Robert Anisko <robert@lrde.epita.fr>
16647 * data/bison.c++: Merge the two generated headers. Insert a copyright
16648 notice in each output file.
16650 2002-02-28 Akim Demaille <akim@epita.fr>
16652 * data/bison.c++: Copy the prologue of bison.simple to fetch
16653 useful M4 definitions, such as b4_header_guard.
16655 2002-02-25 Akim Demaille <akim@epita.fr>
16657 * src/getargs.c (version): Give the name of the authors, and use a
16658 translator friendly scheme for the bgr
16661 2002-02-25 Akim Demaille <akim@epita.fr>
16663 * src/output.c (header_output): Remove, now handled completely via
16666 2002-02-25 Akim Demaille <akim@epita.fr>
16668 * m4/m4.m4: New, from CVS Autoconf.
16669 * configure.in: Invoke it.
16670 * src/output.c (output_skeleton): Use its result instead of the
16673 2002-02-25 Akim Demaille <akim@epita.fr>
16675 * lib/tempname.c, lib/mkstemp.c, m4/mkstemp.m4: New, stolen from
16677 * configure.in: Invoke UTILS_FUNC_MKSTEMP.
16678 * src/output.c (output_skeleton): Use mkstemp to create a real
16680 Move the filling of `skeleton' and its muscle to...
16682 (output): Move the definition of the prologue muscle to...
16684 * src/system.h (DEFAULT_TMPDIR): New.
16686 2002-02-14 Paul Eggert <eggert@twinsun.com>
16688 Remove the support for C++ namespace cleanliness; it was
16689 causing more problems than it was curing, since it didn't work
16690 properly on some nonstandard C++ compilers. This can wait
16691 for a proper C++ parser.
16693 * NEWS: Document this.
16694 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
16695 of C++, as it's treated like C now.
16696 * src/bison.simple (YYSTD): Remove.
16697 (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
16698 Treat C++ just like Standard C instead of trying to support
16699 namespace cleanliness.

16703 * tests/regression.at (else): Adjust to Andreas' change.
16705 2002-02-14 Akim Demaille <akim@epita.fr>
16707 * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
16709 2002-02-13 Andreas Schwab <schwab@suse.de>
16711 * src/output.c (output_rule_data): Don't output NULL, it might
16712 not be defined yet.
16714 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
16716 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
16717 (Copyright notice): Update.
16719 2002-02-11 Akim Demaille <akim@epita.fr>
16721 * tests/regression.at (%nonassoc and eof): Don't include
16722 nonportable headers.
16724 2002-02-08 Robert Anisko <robert@lrde.epita.fr>
16726 * data/bison.c++: Correct error recovery. Make the user able to
16727 initialize the starting location.
16729 2002-02-07 Akim Demaille <akim@epita.fr>
16731 * tests/input.at: New.
16733 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
16735 * data/bison.c++: Replace some direct m4 expansions by constants. Be
16736 more consistent when naming methods and variables. Put preprocessor
16737 directives around tables only needed for debugging.
16739 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
16741 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
16743 (yy::b4_name::parse): Use print_.
16745 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
16747 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
16749 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
16751 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
16753 (yy::b4_name::parse): Build verbose error messages, and use error_.
16755 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
16757 * data/bison.c++: Fix m4 quoting in comments.
16759 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
16761 * data/bison.c++: Adjust the parser code. Fix some muscles that were
16762 not expanded by m4.
16764 2002-02-05 Akim Demaille <akim@epita.fr>
16766 * data/bison.c++: Adjust to the M4 back end.
16767 More is certainly needed.
16769 2002-02-05 Akim Demaille <akim@epita.fr>
16771 Give a try to M4 as a back end.
16773 * lib/readpipe.c: New, from wdiff.
16774 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
16776 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
16777 specific values. Now it is m4 that performs the lookup.
16778 * src/parse-skel.y: Remove.
16779 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
16780 * src/output.c (actions_output, guards_output)
16781 (token_definitions_output): No longer keeps track of the output
16782 line number, hence remove the second argument.
16783 (guards_output): Check against the guard member of a rule, not the
16786 (output_skeleton): Don't look for the skeleton location, let m4 do
16788 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
16790 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
16791 (prepare): Given that for the time being changesyntax is not
16792 usable in M4, rename the muscles using `-' to `_'.
16793 Define `defines_flag', `output_parser_name' and `output_header_name'.
16794 * src/output.h (actions_output, guards_output)
16795 (token_definitions_output): Adjust prototypes.
16796 * src/scan-skel.l: Instead of scanning the skeletons, it now
16797 processes the output of m4: `__oline__' and `#output'.
16798 * data/bison.simple: Adjust to be used by M4(sugar).
16799 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
16801 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
16802 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
16803 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
16804 shamelessly stolen from CVS Autoconf.
16806 2002-02-05 Akim Demaille <akim@epita.fr>
16808 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
16809 * configure.in: Check for the declarations of free and malloc.
16810 * src/muscle_tab.c: Adjust.
16812 2002-02-05 Akim Demaille <akim@epita.fr>
16814 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
16815 which have no values.
16817 2002-02-05 Akim Demaille <akim@epita.fr>
16819 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
16822 2002-01-29 Paul Eggert <eggert@twinsun.com>
16824 * src/bison.simple (YYSIZE_T): Do not define merely because
16825 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
16826 On some platforms, <alloca.h> does not declare YYSTD (size_t).
16828 2002-01-27 Akim Demaille <akim@epita.fr>
16830 Fix `%nonassoc and eof'.
16832 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
16833 which were not properly copied! Replace
16834 memcpy (res->errs, src->errs, src->nerrs);
16836 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
16838 * tests/regression.at (%nonassoc and eof): Adjust to newest
16839 Autotest: `.' is not in the PATH.
16841 2002-01-27 Akim Demaille <akim@epita.fr>
16843 * tests/sets.at (AT_EXTRACT_SETS): New.
16844 (Nullable): Use it.
16847 2002-01-26 Akim Demaille <akim@epita.fr>
16849 * tests/actions.at, tests/calc.at, tests/headers.at,
16850 * tests/torture.at: Adjust to the newest Autotest which no longer
16851 forces `.' in the PATH.
16853 2002-01-25 Akim Demaille <akim@epita.fr>
16855 * tests/regression.at (%nonassoc and eof): New.
16856 Suggested by Robert Anisko.
16858 2002-01-24 Akim Demaille <akim@epita.fr>
16860 Bison dumps core when trying to complain about broken input files.
16861 Reported by Cris van Pelt.
16863 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
16864 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
16866 (Invalid inputs): Strengthen: exercise parse_percent_token.
16868 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
16870 * src/Makefile.am: Add bison.c++.
16871 * src/bison.c++: New skeleton.
16873 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
16877 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
16879 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
16881 2002-01-20 Marc Autret <marc@gnu.org>
16883 * src/files.c (compute_output_file_names): Fix
16885 2002-01-20 Marc Autret <marc@gnu.org>
16887 * tests/output.at: New test.
16888 * src/files.c (compute_base_names): Don't map extensions when
16889 the YACC flag is set, use defaults.
16890 Reported by Evgeny Stambulchik.
16892 2002-01-20 Marc Autret <marc@gnu.org>
16894 * src/system.h: Need to define __attribute__ away for non-GCC
16895 compilers as well (i.e., the vendor C compiler).
16896 Suggested by Albert Chin-A-Young.
16898 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
16900 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
16901 canonical definition.
16902 * src/system.h: Use the canonical definition for PARAMS (avoids
16903 a conflict with the macro from lib/hash.h).
16905 2002-01-11 Akim Demaille <akim@epita.fr>
16907 * configure.in: Use AC_FUNC_STRNLEN.
16908 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
16910 2002-01-09 Akim Demaille <akim@epita.fr>
16912 * src/files.c, src/files.h (output_infix): New.
16913 (tab_extension): Remove.
16914 (compute_base_names): Compute the former, drop the latter.
16915 * src/output.c (prepare): Insert the muscles `output-infix', and
16917 * src/parse-skel.y (string, string.1): New.
16918 (section.header): Use it.
16919 (section.yacc): Remove.
16920 (prefix): Remove too.
16921 * src/scan-skel.l: Adjust.
16922 * src/bison.simple, src/bison.hairy: Adjust.
16924 2002-01-09 Akim Demaille <akim@epita.fr>
16926 * configure.in (WERROR_CFLAGS): Compute it.
16927 * src/Makefile.am (CFLAGS): Pass it.
16928 * tests/atlocal.in (CFLAGS): Idem.
16929 * src/files.c: Fix a few warnings.
16930 (get_extension_index): Remove, unused.
16932 2002-01-08 Akim Demaille <akim@epita.fr>
16934 * src/getargs.c (AS_FILE_NAME): New.
16935 (getargs): Use it to convert DOSish file names.
16936 * src/files.c (base_name): Rename as full_base_name to avoid
16937 clashes with `base_name ()'.
16938 (filename_split): New.
16939 (compute_base_names): N-th rewrite, using filename_split.
16941 2002-01-08 Akim Demaille <akim@epita.fr>
16943 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
16944 New, stolen from the Fileutils 4.1.
16945 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
16946 * configure.in: Check for the presence of memrchr, and of its
16949 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
16951 * lib/hash.h (__P): Added definition for this macro.
16952 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
16953 BUILT_SOURCES, to ensure they are generated first.
16954 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
16955 %error-verbose to allow bootstrapping with bison 1.30x.
16957 2002-01-06 Akim Demaille <akim@epita.fr>
16959 * src/reader.c (parse_braces): Don't fetch the next char, the
16960 convention is to fetch on entry.
16961 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
16962 'switch' without a following semicolon.
16963 * tests/regression.at (braces parsing): New.
16965 2002-01-06 Akim Demaille <akim@epita.fr>
16967 Bison is dead wrong in its RR conflict reports.
16969 * tests/torture.at (GNU Cim Grammar): New.
16970 * src/conflicts.c (count_rr_conflicts): Fix.
16972 2002-01-06 Akim Demaille <akim@epita.fr>
16974 Creating package.m4 from configure.ac causes too many problems.
16976 * tests/Makefile.am (package.m4): Create it by hand,
16977 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
16979 2002-01-06 Akim Demaille <akim@epita.fr>
16981 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
16984 2002-01-04 Paul Eggert <eggert@twinsun.com>
16986 * doc/bison.texinfo (Debugging):
16987 Remove YYSTDERR; it's no longer defined or used.
16988 Also, s/cstdio.h/cstdio/.
16990 2002-01-03 Akim Demaille <akim@epita.fr>
16992 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
16994 2002-01-03 Akim Demaille <akim@epita.fr>
16996 * src/parse-skel.y (process_skeleton): Don't bind the parser's
16997 tracing code to --trace, wait for a better --trace option, with
17000 2002-01-03 Akim Demaille <akim@epita.fr>
17002 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
17003 The ISO C++ standard is extremely clear about it: stderr is
17004 considered a macro, not a regular symbol (see table 94 `Header
17005 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
17006 Therefore std:: does not apply to it. It still does with fprintf.
17007 Also, s/cstdio.h/cstdio/.
17009 2002-01-03 Akim Demaille <akim@epita.fr>
17011 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
17012 for non system headers.
17014 2002-01-02 Akim Demaille <akim@epita.fr>
17016 Equip the skeleton chain with location tracking, runtime trace,
17017 pure parser and scanner.
17019 * src/parse-skel.y: Request a pure parser, locations, and prefix
17021 (%union): Having several members with the same type does not help
17022 type mismatches, simplify.
17023 (YYPRINT, yyprint): New.
17024 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
17025 (skel_error): this.
17027 * src/scan-skel.l: Adjust to these changes.
17028 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
17029 (LOCATION_PRINT, skel_control_t): New.
17031 2001-12-30 Akim Demaille <akim@epita.fr>
17033 * src/parse-skel.y: Get rid of the shift/reduce conflict:
17034 replace `gb' with BLANKS.
17035 * src/scan-skel.l: Adjust.
17037 2001-12-30 Akim Demaille <akim@epita.fr>
17039 * src/system.h: We don't need nor want bcopy.
17040 Throw away MS-DOS crap: we don't need getpid.
17041 * configure.in: We don't need strndup. It was even causing
17042 problems: because Flex includes the headers *before* us,
17043 _GNU_SOURCE is not defined by config.h, and therefore strndup was
17045 * lib/xstrndup.c: New.
17046 * src/scan-skel.l: Use it.
17047 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
17048 * src/parse-skel.y: Use %directives instead of #defines.
17050 2001-12-30 Akim Demaille <akim@epita.fr>
17052 * src/skeleton.h: New.
17053 * src/output.c (output_parser, output_master_parser): Remove, dead
17055 * src/output.h (get_lines_number, actions_output, guards_output)
17056 (token_definitions_output): Prototype them.
17057 * src/parse-skel.y: Add the license notice.
17058 Include output.h and skeleton.h.
17059 (process_skeleton): Returns void, and takes a single parameter.
17060 * src/scan-skel.l: Add the license notice.
17061 Include skeleton.h.
17062 Don't use %option yylineno: it seems that then Flex imagines
17063 REJECT has been used, and therefore it won't reallocate its
17064 buffers (which makes no other sense to me than a bug). It results
17065 in warnings for `unused: yy_flex_realloc'.
17067 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
17069 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
17070 (MUSCLE_INSERT_PREFIX): ...to there.
17071 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
17072 (MUSCLE_INSERT_PREFIX): Move from here...
17074 * src/bison.hairy: Add a section directive. Put braces around muscle
17075 names. This parser skeleton is still broken, but Bison should not
17076 choke on a bad muscle 'syntax'.
17077 * src/bison.simple: Add a section directive. Put braces around muscle
17080 * src/files.h (strsuffix, stringappend): Add declarations.
17081 (tab_extension): Add declaration.
17082 (short_base_name): Add declaration.
17084 * src/files.c (strsuffix, stringappend): No longer static. These
17085 functions are used in the skeleton parser.
17086 (tab_extension): New.
17087 (compute_base_names): Use the computations done in this function
17088 to guess if the generated parsers should have '.tab' in their
17090 (short_base_name): No longer static.
17092 * src/output.c (output_skeleton): New.
17093 (output): Disable call to output_master_parser, and give a try to
17094 a new skeleton handling system.
17095 (guards_output, actions_output): No longer static.
17096 (token_definitions_output, get_lines_number): No longer static.
17098 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
17100 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
17103 * src/parse-skel.y: New file.
17104 * src/scan-skel.l: New file.
17106 2001-12-29 Akim Demaille <akim@epita.fr>
17108 %name-prefix is broken.
17110 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
17111 Adjust all dependencies.
17112 * tests/headers.at (export YYLTYPE): Strengthen this test: use
17115 Renaming yylval but not yylloc is not consistent. Now we do.
17117 * src/bison.simple: Prefix yylloc if used.
17118 * doc/bison.texinfo (Decl Summary): Document that.
17120 2001-12-29 Akim Demaille <akim@epita.fr>
17122 * doc/bison.texinfo: Promote `%long-directive' over
17124 Remove all references to fixed-output-files, yacc is enough.
17126 2001-12-29 Akim Demaille <akim@epita.fr>
17128 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
17129 user prologue. These are defaults.
17130 * tests/actions.at (Mid-rule actions): Make sure the user can
17131 define YYDEBUG and YYERROR_VERBOSE.
17133 2001-12-29 Akim Demaille <akim@epita.fr>

17137 * tests/headers.at (export YYLTYPE): New, make sure it does.
17138 * tests/regression.at (%union and --defines, Invalid CPP headers):
17140 * tests/headers.at: here.
17142 2001-12-29 Akim Demaille <akim@epita.fr>
17144 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
17146 2001-12-29 Akim Demaille <akim@epita.fr>
17148 * tests/actions.at (Mid-rule actions): Output on a single line
17149 instead of several.
17151 2001-12-29 Akim Demaille <akim@epita.fr>
17153 * doc/bison.texinfo: Formatting changes.
17155 2001-12-29 Akim Demaille <akim@epita.fr>
17157 Don't store the token defs in a muscle, just be ready to output it
17158 on command. Now possible via `symbols'. Fixes a memory leak.
17160 * src/output.c (token_definitions_output): New.
17161 (output_parser, header_output): Use it.
17162 * src/reader.c (symbols_save): Remove.
17164 2001-12-29 Akim Demaille <akim@epita.fr>
17166 * src/bison.simple: Do not provide a default for YYSTYPE and
17167 YYLTYPE before the user's prologue. Otherwise it's hardly... a
17170 2001-12-29 Akim Demaille <akim@epita.fr>
17172 Mid-rule actions are simply... ignored!
17174 * src/reader.c (readgram): Be sure to attach mid-rule actions to
17175 the empty-rule associated to the dummy symbol, not to the host
17177 * tests/actions.at (Mid-rule actions): New.
17179 2001-12-29 Akim Demaille <akim@epita.fr>
17183 * src/reader.c (reader): Free grammar.
17185 2001-12-29 Akim Demaille <akim@epita.fr>
17189 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
17190 since it allocates it for each state, although only one is needed.
17191 (allocate_storage): Do it here.
17193 2001-12-29 Akim Demaille <akim@epita.fr>
17195 * src/options.h, src/options.c (create_long_option_table): Rename
17197 (long_option_table_new): this, with a clearer prototype.
17198 (percent_table): Remove, unused,
17199 * src/getargs.c (getargs): Adjust.
17201 2001-12-29 Akim Demaille <akim@epita.fr>
17203 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c

17207 2001-12-29 Akim Demaille <akim@epita.fr>
17209 * src/lalr.c (build_relations): Rename `states' as `states1'.
17210 Sorry, I don't understand exactly what it is, no better name...
17212 2001-12-29 Akim Demaille <akim@epita.fr>
17214 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
17215 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c

17231 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
17232 Adjust all users to use symbols[i]->prec or ->assoc.

17237 Adjust all users to use symbols[i]->tag.
17239 2001-12-29 Akim Demaille <akim@epita.fr>
17241 * src/gram.h, src/gram.c (symbols): New, similar to state_table
17243 * src/reader.c (packsymbols): Fill this table.
17245 * src/conflicts.c (resolve_sr_conflict): Adjust.
17246 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
17248 Use symbols[i]->tag instead of tags[i].
17250 2001-12-29 Akim Demaille <akim@epita.fr>
17252 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
17253 In addition, put a comment in there, to replace...
17254 * tests/regression.at (%union and C comments): Remove.
17256 2001-12-29 Akim Demaille <akim@epita.fr>
17258 * tests/regression.at (Web2c Actions): Blindly move the actual
17259 output as expected output. The contents *seem* right to me, but I
17260 can't pretend reading perfectly parser tables... Nonetheless, all
17261 the other tests pass correctly, the table look OK, even though the
17262 presence of `$axiom' is to be noted: AFAICS it is useless (but
17265 2001-12-29 Akim Demaille <akim@epita.fr>
17267 * src/reader.c (readgram): Don't add the rule 0 if there were no
17268 rules read. In other words, add it _after_ having performed
17269 grammar sanity checks.
17270 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
17272 2001-12-29 Akim Demaille <akim@epita.fr>
17274 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
17275 visible, and some states have now a different number.
17277 2001-12-29 Akim Demaille <akim@epita.fr>
17279 * src/reader.c (readgram): Bind the initial rule's lineno to that
17281 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
17282 (Solved SR Conflicts): Adjust rule 0's line number.
17284 2001-12-29 Akim Demaille <akim@epita.fr>
17286 Fix the `GAWK Grammar' failure.
17288 * src/LR0.c (final_state): Initialize to -1 so that we do compute
17289 the reductions of the first state which was mistakenly confused
17290 with the final state because precisely final_state was initialized
17292 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
17293 now noticed by Bison.
17294 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
17295 have a reduction on $default.
17297 2001-12-29 Akim Demaille <akim@epita.fr>
17299 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
17301 * src/closure.c (print_closure): Likewise.
17302 * src/derives.c (print_derives): Likewise.
17303 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
17306 2001-12-29 Akim Demaille <akim@epita.fr>
17308 * src/lalr.c (lookaheads_print): New.
17309 (lalr): Call it when --trace-flag.
17310 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
17313 2001-12-29 Akim Demaille <akim@epita.fr>
17315 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
17316 when walking through ritem, even via rule->rhs.
17317 * src/reduce.c (dump_grammar, useful_production, reduce_output)
17318 (useful_production, useless_nonterminals): Likewise.
17319 (reduce_grammar_tables): Likewise, plus update nritems.
17320 * src/nullable.c (set_nullable): Likewise.
17321 * src/lalr.c (build_relations): Likewise.
17322 * tests/sets.at (Nullable): Adjust.
17323 Fortunately, now, the $axiom is no longer nullable.
17325 2001-12-29 Akim Demaille <akim@epita.fr>
17327 * src/LR0.c (generate_states): Use nritems, not nitems, nor using

17330 * src/reduce.c (nonterminals_reduce): Likewise.
17331 * src/print_graph.c (print_graph): Likewise.

17333 * src/nullable.c (set_nullable): Likewise.
17335 2001-12-29 Akim Demaille <akim@epita.fr>
17337 * src/output.c: Comment changes.
17339 2001-12-27 Paul Eggert <eggert@twinsun.com>
17341 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
17342 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
17343 Sparc, as they were causing more porting problems than the
17344 (minor) performance improvement was worth.
17346 Also, catch up with 1.31's YYSTD.
17348 2001-12-27 Akim Demaille <akim@epita.fr>
17350 * src/output.c (output_gram): Rely on nritems, not the
17351 0-sentinel. See below.
17352 Use -1 as separator, not 0.
17353 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
17354 Rely on -1 as separator in yyrhs, instead of 0.
17355 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
17356 twice `Now at end of input', therefore there are two lines less to
17359 2001-12-27 Akim Demaille <akim@epita.fr>
17361 * tests/regression.at (Unresolved SR Conflicts):
17362 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
17365 2001-12-27 Akim Demaille <akim@epita.fr>
17367 * src/LR0.c (new_state): Recognize the final state by the fact it
17368 is reached by eoftoken.
17369 (insert_start_shifting_state, insert_eof_shifting_state)
17370 (insert_accepting_state, augment_automaton): Remove, since now
17371 these states are automatically computed from the initial state.
17372 (generate_states): Adjust.
17373 * src/print.c: When reporting a rule number to the user, substract
17374 1, so that the axiom rule is rule 0, and the first user rule is 1.
17375 * src/reduce.c: Likewise.
17376 * src/print_graph.c (print_core): For the time being, just as for
17377 the report, depend upon --trace-flags to dump the full set of
17379 * src/reader.c (readgram): Once the grammar read, insert the rule
17380 0: `$axiom: START-SYMBOL $'.
17381 * tests/set.at: Adjust: rule 0 is now displayed, and since the
17382 number of the states has changed (the final state is no longer
17383 necessarily the last), catch up.
17385 2001-12-27 Akim Demaille <akim@epita.fr>
17387 Try to make the use of the eoftoken valid. Given that its value
17388 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
17389 is used instead of > 0 where appropriate, (ii), depend upon nritems
17390 instead of the 0-sentinel.
17392 * src/gram.h, src/gram.c (nritems): New.
17393 Expected to be duplication of nitems, but for the time being...
17394 * src/reader.c (packgram): Assert nritems and nitems are equal.
17395 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
17396 * src/closure.c (print_closure, print_fderives): Likewise.
17397 * src/gram.c (ritem_print): Likewise.
17398 * src/print.c (print_core, print_grammar): Likewise.
17399 * src/print_graph.c: Likewise.
17401 2001-12-27 Akim Demaille <akim@epita.fr>
17403 * src/main.c (main): If there are complains after grammar
17404 reductions, then output the report anyway if requested, then die.
17405 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
17406 * src/reader.c (eoftoken): New.
17407 (parse_token_decl): If the token being defined has value `0', it
17409 (packsymbols): No longer hack `tags' to insert `$' by hand.
17410 Be sure to preserve the value of the eoftoken.
17411 (reader): Make sure eoftoken is defined.
17412 Initialize nsyms to 0: now eoftoken is created just like the others.
17413 * src/print.c (print_grammar): Don't special case the eof token.
17414 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
17415 lie anyway, albeit pleasant.
17416 * tests/calc.at: Exercise error messages with eoftoken.
17417 Change the grammar so that empty input is invalid.
17418 Adjust expectations.
17419 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
17421 2001-12-27 Akim Demaille <akim@epita.fr>
17423 * configure.in: Check the protos of strchr ans strspn.
17424 Replace strchr if needed.
17425 * src/system.h: Provide the protos of strchr, strspn and memchr if
17427 * lib/strchr.c: New.
17428 * src/reader.c (symbols_save): Use strchr.
17430 2001-12-27 Akim Demaille <akim@epita.fr>
17432 * src/print.c, src/print_graph.c (escape): New.
17433 Use it to quote the TAGS outputs.
17434 * src/print_graph.c (print_state): Now errors are in red, and
17435 reductions in green.
17436 Prefer high to wide: output the state number on a line of its own.
17438 2001-12-27 Akim Demaille <akim@epita.fr>
17440 * src/state.h, src/state.c (reductions_new): New.
17441 * src/LR0.c (set_state_table): Let all the states have a
17442 `reductions', even if reduced to 0.
17443 (save_reductions): Adjust.

17461 2001-12-27 Akim Demaille <akim@epita.fr>
17463 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
17464 * src/print.c: here.
17465 (lookaheadset, shiftset): New, used as additional storage by
17467 (print_results): Adjust.
17468 (print_shifts, print_gotos, print_errs): New, extracted from...
17469 (print_actions): here.
17470 * src/print_graph.c (print_actions): Remove dead code.
17472 2001-12-27 Akim Demaille <akim@epita.fr>
17474 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
17477 2001-12-27 Akim Demaille <akim@epita.fr>
17479 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
17480 (build_relations): Adjust.
17482 2001-12-27 Akim Demaille <akim@epita.fr>
17484 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
17487 2001-12-27 Akim Demaille <akim@epita.fr>
17489 * src/reader.c (packgram): Catch nitems overflows.
17491 2001-12-27 Akim Demaille <akim@epita.fr>
17493 * src/files.c, src/files.h (guard_obstack): Remove.
17494 * src/output.c (output): Adjust.
17495 * src/reader.c (parse_braces): New, factoring...
17496 (copy_action, copy_guard): these two which are renamed as...
17497 (parse_action, parse_guard): these.
17498 As a voluntary consequence, using braces around guards is now
17501 2001-12-27 Akim Demaille <akim@epita.fr>
17503 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
17504 * src/reader.c (symbol_list): `guard' and `guard_line' are new
17506 (symbol_list_new): Adjust.
17507 (copy_action): action_line is the first line, not the last.
17508 (copy_guard): Just as for actions, store the `action' only, not
17509 the switch/case/break flesh.
17510 Don't parse the user action that might follow the guard, let...
17511 (readgram): do it, i.e., now, there can be an action after a
17513 In other words the guard is just explicitly optional.
17514 (packgram): Adjust.
17515 * src/output.c (guards_output): New.
17516 (output_parser): Call it when needed.
17517 (output): Also free the guard and attrs obstacks.
17518 * src/files.c, src/files.h (obstack_save): Remove.
17519 (output_files): Remove.
17520 As a result, if one needs the former `.act' file, using an
17521 appropriate skeleton which requires actions and guards is now
17523 * src/main.c (main): Adjust.
17524 * tests/semantic.at: New.
17525 * tests/regression.at: Use `input.y' as input file name.
17526 Avoid 8+3 problems by requiring input.c when the test needs the

17531 * src/reader.c (symbol_list_new): Be sure to initialize all the
17534 2001-12-27 Akim Demaille <akim@epita.fr>
17536 All the hacks using a final pseudo state are now useless.
17538 * src/LR0.c (set_state_table): state_table holds exactly nstates.
17539 * src/lalr.c (nLA): New.
17540 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
17541 instead of lookaheadsp from the pseudo state (nstate + 1).
17543 2001-12-27 Akim Demaille <akim@epita.fr>
17545 * src/output.c (action_row, token_actions): Use a state_t instead
17546 of a integer, and nlookaheads instead of the following state's

17553 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
17554 (conflicts_print, print_reductions): Use a state_t instead of an
17555 integer when referring to a state.
17556 As much as possible, depend upon nlookaheads, instead of the
17557 `lookaheadsp' member of the following state (since lookaheads of
17558 successive states are successive, the difference between state n + 1
17559 and n served as the number of lookaheads for state n).
17560 * src/lalr.c (add_lookback_edge): Likewise.
17561 * src/print.c (print_core, print_actions, print_state)
17562 (print_results): Likewise.

17572 Add plenty of `static'.
17574 2001-12-27 Akim Demaille <akim@epita.fr>
17576 * src/output.c (prepare): Drop the muscle `ntbase' which
17577 duplicates ntokens.
17578 * src/bison.simple: Formatting/comment changes.
17579 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
17580 is an undocumented synonym.
17582 2001-12-22 Akim Demaille <akim@epita.fr>
17584 * src/output.c (output_table_data): Change the prototype to use
17585 `int' for array ranges: some invocations do pass an int, not a
17587 Reported by Wayne Green.
17589 2001-12-22 Akim Demaille <akim@epita.fr>
17591 Some actions of web2c.y are improperly triggered.
17592 Reported by Mike Castle.
17594 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.

17596 (Web2c Report): this.
17597 (Web2c Actions): New.
17599 2001-12-22 Akim Demaille <akim@epita.fr>
17601 Reductions in web2c.y are improperly reported.
17602 Reported by Mike Castle.

17605 * tests/regression.at (Web2c): New.
17607 2001-12-18 Akim Demaille <akim@epita.fr>
17609 Some host fail on `assert (!"foo")', which expands to
17610 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
17611 Reported by Nelson Beebee.
17613 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
17614 `#define it_succeeded 0' and `assert (it_succeeded)'.
17616 2001-12-17 Marc Autret <autret_m@epita.fr>
17618 * src/bison.simple: Don't hard code the skeleton line and filename.
17619 * src/output.c (output_parser): Rename 'line' as 'output_line'.
17620 New line counter 'skeleton_line' (skeleton-line muscle).
17622 2001-12-17 Paul Eggert <eggert@twinsun.com>
17624 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
17625 YYDEBUG must be defined to a nonzero value.
17627 * src/bison.simple (yytname): Do not assume that the user defines
17628 YYDEBUG to a properly parenthesized expression.
17630 2001-12-17 Akim Demaille <akim@epita.fr>
17632 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
17633 nlookaheads is a new member.
17635 * src/lalr.h (nlookaheads): Remove this orphan declaration.
17636 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
17639 2001-12-17 Akim Demaille <akim@epita.fr>
17641 * src/files.h, src/files.c (open_files, close_files): Remove.
17642 * src/main.c (main): Don't open/close files, nor invoke lex_free,
17644 * src/reader.c (reader): Do it.
17646 2001-12-17 Akim Demaille <akim@epita.fr>
17648 * src/conflicts.c (print_reductions): Formatting changes.
17650 2001-12-17 Akim Demaille <akim@epita.fr>
17652 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
17653 (flush_reduce): New.
17654 (resolve_sr_conflict): Adjust.
17656 2001-12-17 Akim Demaille <akim@epita.fr>
17658 * src/output.c (output_obstack): Be static and rename as...
17659 (format_obstack): this, to avoid any confusion with files.c's
17661 * src/reader.h (muscle_obstack): Move to...
17662 * src/output.h: here, since it's defined in output.c.
17664 2001-12-17 Akim Demaille <akim@epita.fr>
17666 * src/output.c (action_row, save_column, default_goto)
17667 (sort_actions, matching_state, pack_vector): Better variable
17670 2001-12-17 Akim Demaille <akim@epita.fr>
17672 * src/output.c: Various formatting changes.
17674 2001-12-17 Akim Demaille <akim@epita.fr>
17676 * src/files.c (output_files): Free the output_obstack.
17677 * src/main.c (main): Call print and print_graph conditionally.
17678 * src/print.c (print): Work unconditionally.
17679 * src/print_graph.c (print_graph): Work unconditionally.
17680 * src/conflicts.c (log_resolution): Output only if verbose_flag.
17682 2001-12-16 Marc Autret <autret_m@epita.fr>
17684 * src/output.c (actions_output): Fix. When we use %no-lines,
17685 there is one less line per action.
17687 2001-12-16 Marc Autret <autret_m@epita.fr>
17689 * src/bison.simple: Remove a useless #line directive.
17690 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
17691 * src/output.c (get_lines_number): New.
17692 (output_parser): Adjust, now takes care about the lines of a
17694 Fix line numbering.
17695 (actions_output): Computes the number of lines taken by actions.
17696 (output_master_parser): Insert new skeleton which is the name of
17697 the output parser file name.
17699 2001-12-15 Marc Autret <autret_m@epita.fr>
17701 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
17703 2001-12-15 Marc Autret <autret_m@epita.fr>
17705 * src/output.c (output_gram): Keep track of the hairy one.
17707 2001-12-15 Akim Demaille <akim@epita.fr>
17709 Make `make distcheck' work.
17711 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
17712 system.h which uses libgettext.h.
17714 2001-12-15 Akim Demaille <akim@epita.fr>
17716 * src/nullable.c (set_nullable): Useless rules must be skipped,
17717 otherwise, since we range over their symbols, we might look at a
17718 nonterminal which no longer ``exists'', i.e., it is not counted in
17719 `nvars', hence we overflow our arrays.
17721 2001-12-15 Akim Demaille <akim@epita.fr>
17723 The header can also be produced directly, without any obstack!
17726 * src/files.c, src/files.h (defines_obstack): Remove.
17727 (compute_header_macro): Global.
17728 (defines_obstack_save): Remove.
17729 * src/reader.c (parse_union_decl): No longer output to
17730 defines_obstack: its content can be found in the `stype' muscle
17732 (output_token_translations): Merge into...
17733 (symbols_output): this.
17735 (symbols_save): this.
17737 * src/output.c (header_output): New.
17740 2001-12-15 Akim Demaille <akim@epita.fr>
17742 * src/reader.c (parse_union_decl): Instead of handling two obstack
17743 simultaneously, use one to define the `stype' muscle, and use the
17744 value of the latter to fill defines_obstack.
17745 (copy_comment): Remove.
17746 (copy_comment2): Work for a single obstack.
17748 (copy_comment): this.
17750 2001-12-15 Akim Demaille <akim@epita.fr>
17752 * src/lex.c, src/lex.h (xgetc): No longer static.
17753 * src/reader.c (parse_union_decl): Revamp.
17755 2001-12-15 Akim Demaille <akim@epita.fr>
17757 Still making progress in separating Bison into (i) input, (ii)
17758 process, (iii) output: now we can directly output the parser file
17759 without using table_obstack at all.
17761 * src/files.c, src/files.h (table_obstack): Bye bye.
17762 (parser_file_name): New.
17763 * src/files.c (compute_output_file_names): Compute it.
17764 * src/output.c (actions_output, output_parser)
17765 (output_master_parser): To a file instead of an obstack.
17767 2001-12-15 Akim Demaille <akim@epita.fr>
17769 Attach actions to rules, instead of pre-outputting them to
17772 * src/gram.h (rule_t): action and action_line are new members.
17773 * src/reader.c (symbol_list): Likewise.
17774 (copy_action): Save the actions within the rule.
17775 (packgram): Save them in rule_table.
17776 * src/output.c (actions_output): New.
17777 (output_parser): Use it on `%%actions'.
17778 (output_rule_data): Don't free rule_table.
17780 (prepare): Don't save the `action' muscle.
17781 * src/bison.simple: s/%%action/%%actions/.
17783 2001-12-15 Akim Demaille <akim@epita.fr>
17785 * src/reader.c (copy_action): When --yacc, don't append a `;'
17786 to the user action: let it fail if lacking.
17787 Suggested by Arnold Robbins and Tom Tromey.
17789 2001-12-14 Akim Demaille <akim@epita.fr>
17791 * src/lex.c (literalchar): Simply return the char you decoded, non
17792 longer mess around with obstacks and int pointers.
17793 Adjust all callers.
17795 2001-12-14 Akim Demaille <akim@epita.fr>
17797 * src/lex.c (literalchar): Don't escape the special characters,
17798 just decode them, and keep them as char (before, eol was output as
17799 the 2 char string `\n' etc.).
17800 * src/output.c (output_rule_data): Use quotearg to output the
17803 2001-12-13 Paul Eggert <eggert@twinsun.com>
17805 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
17806 Do not infringe on the global user namespace when using C++.
17807 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
17808 All uses of `fprintf' and `stderr' changed.
17810 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
17812 2001-12-13 Akim Demaille <akim@epita.fr>
17814 The computation of nullable is broken: it doesn't handle empty
17817 * tests/torture.at (GNU AWK Grammar): New.
17818 * tests/sets.at (Nullable): New.
17819 * src/nullable.c (set_nullable): Instead of blindly looping over
17820 `ritems', loop over the rules, and then over their rhs's.
17822 Work around Autotest bugs.
17824 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
17825 frame, because Autotest understand lines starting with a `+' as
17826 traces from the shell. Then, they are not processed properly.
17827 Admittedly an Autotest bug, but we don't have time to wait for
17828 Autotest to catch up.
17829 * tests/regression.at (Broken Closure): Adjust to the new table
17832 * tests/sets.at: here.
17834 2001-12-13 Akim Demaille <akim@epita.fr>
17836 * src/closure.c (closure): Use nrules instead of playing tricks
17837 with BITS_PER_WORD.
17839 2001-12-13 Akim Demaille <akim@epita.fr>
17841 * src/print.c (print_actions): Output the handling of `$' as the
17842 traces do: shifting the token EOF. Before EOF was treated as a
17844 * tests/regression.at: Adjust some tests.
17845 * src/print_graph.c (print_core): Complete the set of items via
17846 closure. The next-to-final and final states are still unsatisfying,
17847 but that's to be addressed elsewhere.
17848 No longer output the rule numbers, but do output the state number.
17849 A single loop for the shifts + gotos is enough, but picked a
17850 distinct color for each.
17851 (print_graph): Initialize and finalize closure.
17853 2001-12-13 Akim Demaille <akim@epita.fr>
17855 * src/reader.c (readgram): Remove dead code, an strip useless
17857 (get_type): Remove, unused.
17859 2001-12-12 Akim Demaille <akim@epita.fr>
17861 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
17862 on that of lib/error.c.
17864 2001-12-12 Akim Demaille <akim@epita.fr>
17866 Some hosts don't like `/' in includes.
17868 * src/system.h: Include libgettext.h without qualifying the path.
17869 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
17872 2001-12-11 Marc Autret <autret_m@epita.fr>
17874 * src/output.c (output_parser): Remove useless muscle.
17876 2001-12-11 Marc Autret <autret_m@epita.fr>
17878 * src/bison.simple: Remove #line just before %%epilogue. It
17879 is now handled in ...
17880 * src/reader.c (read_additionnal_code): Add the output of a
17881 #line for the epilogue.
17883 2001-12-10 Marc Autret <autret_m@epita.fr>
17885 * src/reader.c (copy_definition): Re-use CPP-outed code which
17886 replace precedent remove.
17887 * src/bison.simple: Remove #line before %%prologue because
17888 %%input-line is wrong at this time.
17890 2001-12-10 Marc Autret <autret_m@epita.fr>
17892 * src/reader.c (symbols_output): Clean up.
17893 * src/output.c (output_gram, output): Clean up.
17895 2001-12-10 Akim Demaille <akim@epita.fr>
17897 * src/lalr.c (initialize_lookaheads): New. Extracted from...
17898 * src/LR0.c (set_state_table): here.
17899 * src/lalr.c (lalr): Call it.
17901 2001-12-10 Akim Demaille <akim@epita.fr>
17903 * src/state.h (shifts): Remove the `number' member: shifts are
17904 attached to state, hence no longer need to be labelled with a
17907 2001-12-10 Akim Demaille <akim@epita.fr>
17909 Now that states have a complete set of members, the linked list of
17910 shifts is useless: just fill directly the state's shifts member.
17912 * src/state.h (shifts): Remove the `next' member.
17913 * src/LR0.c (first_state, last_state): Remove.
17914 Adjust the callers.
17915 (augment_automaton): Don't look for the shifts that must be added
17916 a shift on EOF: it is those of the state we looked for! But now,
17917 since shifts are attached, it is no longer needed to looking
17918 merely by its id: its number.
17920 2001-12-10 Akim Demaille <akim@epita.fr>
17922 * src/LR0.c (augment_automaton): Better variable locality.
17923 Remove an impossible branch: if there is a state corresponding to
17924 the start symbol being shifted, then there is shift for the start
17925 symbol from the initial state.
17927 2001-12-10 Akim Demaille <akim@epita.fr>
17929 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
17930 only when appropriate: when insert_start_shifting_state' is not
17932 * tests/regression.at (Rule Line Numbers): Adjust.
17934 2001-12-10 Akim Demaille <akim@epita.fr>
17936 * src/LR0.c (augment_automaton): Now that all states have shifts,
17937 merge the two cases addition shifts to the initial state.
17939 2001-12-10 Akim Demaille <akim@epita.fr>
17941 * src/lalr.c (set_state_table): Move to...
17943 * src/lalr.c (lalr): Don't call it...
17944 * src/LR0.c (generate_states): do it.
17945 * src/LR0.h (first_state): Remove, only the table is used.
17947 2001-12-10 Akim Demaille <akim@epita.fr>
17949 * src/LR0.h (first_shift, first_reduction): Remove.
17950 * src/lalr.c: Don't use first_shift: find shifts through the
17953 2001-12-10 Akim Demaille <akim@epita.fr>
17955 * src/LR0.c: Attach shifts to states as soon as they are
17957 * src/lalr.c (set_state_table): Instead of assigning shifts to
17958 state, just assert that the mapping was properly done.
17960 2001-12-10 Akim Demaille <akim@epita.fr>
17962 * src/LR0.c (insert_start_shift): Rename as...
17963 (insert_start_shifting_state): this.
17964 (insert_eof_shifting_state, insert_accepting_state): New.
17965 (augment_automaton): Adjust.
17966 Better locality of the variables.
17967 When looking if the start_symbol is shifted from the initial
17968 state, using `while (... symbol != start_symbol ...)' sounds
17969 better than `while (... symbol < start_symbol ...)': If fail
17970 to see how the order between symbols could be relevant!
17972 2001-12-10 Akim Demaille <akim@epita.fr>
17974 * src/getargs.h: Don't declare `spec_name_prefix' and
17975 `spec_file_prefix', declared by src/files.h.
17976 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
17977 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
17978 * src/output.c (prepare): Adjust.
17979 * src/reader.c (symbols_output): Likewise.
17980 * src/vmsgetargs.c: Vaguely adjust, but who cares?
17982 2001-12-10 Akim Demaille <akim@epita.fr>
17984 * src/muscle_tab.c (muscle_init): NULL is a better default than
17987 2001-12-10 Akim Demaille <akim@epita.fr>
17989 * src/reader.c (reader): Calling symbols_output once is enough.
17991 2001-12-10 Akim Demaille <akim@epita.fr>
17993 Now that states have a complete set of members, the linked list of
17994 reductions is useless: just fill directly the state's reductions
17997 * src/state.h (struct reductions): Remove member `number' and
17999 * src/LR0.c (first_reduction, last_reduction): Remove.
18000 (save_reductions): Don't link the new reductions, store them in
18002 * src/lalr.c (set_state_table): No need to attach reductions to
18003 states, it's already done.
18004 * src/output.c (output_actions): No longer free the shifts, then
18005 the reductions, then the states: free all the states and their
18008 2001-12-10 Akim Demaille <akim@epita.fr>
18010 * src/options.c (OPTN, DRTV, BOTH): New.
18011 (option_table): Use them.
18013 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
18014 the job of system.h.
18015 * src/options.c: Don't include stdio.h and xalloc.h for the same
18018 2001-12-10 Akim Demaille <akim@epita.fr>
18020 * src/output.c (output, prepare): Make sure the values of the
18021 muscles `action' and `prologue' are 0-terminated.
18023 2001-12-10 Akim Demaille <akim@epita.fr>
18025 Clean up GCC warnings.
18027 * src/reader.c (copy_action): `buf' is not used.
18028 (parse_skel_decl): Be static.
18029 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
18030 * src/options.h (create_long_option_table): Have a real prototype.
18031 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
18032 (hash_delete_at): Return const void *.
18033 Adjust casts to preserve the const.
18035 2001-12-10 Akim Demaille <akim@epita.fr>
18037 * configure.in: Require 2.52g.
18038 M4 is not needed, but AUTOM4TE is.
18039 * m4/m4.m4: Remove.
18040 * tests/Makefile.am: Adjust.
18042 2001-12-10 Akim Demaille <akim@epita.fr>
18044 One structure for states is enough, even though theoretically
18045 there are LR(0) states and LALR(1) states.
18047 * src/lalr.h (state_t): Remove.
18048 (state_table): Be state_t **, not state_t *.
18049 * src/state.h (core, CORE_ALLOC): Rename as...
18050 (state_t, STATE_ALLOC): this.
18051 Add the LALR(1) members: shifts, reductions, errs.
18052 * src/LR0.c (state_table): Rename as...
18053 (state_hash): this, to avoid name clashes with the global
18055 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
18056 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
18058 2001-12-10 Akim Demaille <akim@epita.fr>
18060 Bison dumps core on bash.y.
18061 Reported by Pascal Bart.
18063 * src/warshall.c (bitmatrix_print): New.
18065 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
18066 j must be the outer loop.
18067 * tests/regression.at (Broken Closure): New.
18069 2001-12-05 Akim Demaille <akim@epita.fr>
18071 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
18073 Reported by Peter Hamorsky.
18075 2001-12-05 Akim Demaille <akim@epita.fr>
18077 * src/conflicts.c (err_table): Remove.
18078 (resolve_sr_conflict): Adjust.
18079 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
18081 (state_t.reductions, state_t.shifts): this.
18083 2001-12-05 Akim Demaille <akim@epita.fr>
18085 * src/reduce.c (reduce_grammar_tables): No longer disable the
18086 removal of useless rules via CPP but via `if (0)', so that the
18087 compiler still check the code is valid.
18088 For instance, it should have noticed `rline' no longer exists: use
18089 the `line' member of rule_t.
18090 * src/gram.c (dummy, rline): Remove, unused.
18092 2001-12-05 Akim Demaille <akim@epita.fr>
18094 * src/output.c (pack_vector): Use assert, not berror.
18095 * src/main.c (berror): Remove, unused.
18097 2001-12-05 Akim Demaille <akim@epita.fr>
18099 New experimental feature: if --verbose --trace output all the
18100 items of a state, not only its kernel.
18102 * src/print.c (print_core): If `trace_flag', then invoke closure
18103 before outputting the items of the state (print_core is no longer
18104 a correct name them).
18105 (print_results): Invoke new_closure/free_closure if needed.
18107 2001-12-05 Akim Demaille <akim@epita.fr>
18109 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
18110 * src/closure.c, src/closure.h (itemsetsize): Rename as...
18111 (nitemset): for consistency with the rest of the project.
18113 2001-12-05 Akim Demaille <akim@epita.fr>
18115 * src/closure.c (print_closure): Improve.
18116 (closure): Use it for printing input and output.
18118 2001-12-05 Akim Demaille <akim@epita.fr>
18120 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
18121 indexed by nonterminals.
18123 2001-12-05 Akim Demaille <akim@epita.fr>
18125 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
18127 * src/warshall.h: Remove accidental duplication of the content.
18129 2001-12-05 Akim Demaille <akim@epita.fr>
18131 * src/closure.c (set_fderives): De-obfuscate.
18133 2001-12-05 Akim Demaille <akim@epita.fr>

18139 * src/closure.c (set_firsts): De-obfuscate.
18141 2001-12-05 Akim Demaille <akim@epita.fr>
18143 * src/output.c (action_row): De-obfuscate
18144 using the good o' techniques: arrays not pointers, variable
18145 locality, BITISSET, RESETBIT etc.
18147 2001-12-05 Akim Demaille <akim@epita.fr>
18149 Pessimize the code to simplify it: from now on, all the states
18150 have a valid SHIFTS, which NSHIFTS is possibly 0.
18152 * src/LR0.c (shifts_new): Be global and move to..
18153 * src/state.c, src/state.h: here.
18154 * src/conflicts, src/lalr.c, src/output.c, src/print.c,

18166 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
18167 using the good o' techniques: arrays not pointers, variable
18168 locality, BITISSET, RESETBIT etc.
18170 2001-12-05 Akim Demaille <akim@epita.fr>
18172 * src/state.h (SHIFT_SYMBOL): New.

18220 * src/lalr.c (maxrhs): Move to...
18221 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
18222 * src/lalr.c (build_relations): Adjust.
18224 2001-12-05 Akim Demaille <akim@epita.fr>
18226 * src/lalr.c (transpose): Free the memory allocated to the
18227 argument, as it is replaced by the results by the unique caller.
18228 (build_relations): Merely invoke transpose: it handles the memory
18230 Improve variable locality.
18231 Avoid variables used as mere abbreviations.
18232 (compute_lookaheads): Use arrays instead of pointers.
18234 2001-12-05 Akim Demaille <akim@epita.fr>
18236 * src/lalr.c (initialize_F): Improve variable locality.
18237 Avoid variables used as mere abbreviations.

18252 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
18253 the handling of squeue.
18254 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
18256 2001-12-05 Akim Demaille <akim@epita.fr>
18258 Because useless nonterminals are now kept alive (instead of being
18259 `destroyed'), we now sometimes examine them, and store information
18260 related to them. Hence we need to know their number, and adjust
18261 memory allocations.
18263 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
18265 * src/LR0.c (allocate_itemsets): The memory allocated to
18266 `symbol_count' was used for two different purpose: once to count
18267 the number of occurrences of each symbol, and later reassigned to
18268 `shift_symbol', containing the symbol that can be shifted from a
18270 Deobfuscate, i.e., allocate, use and free `symbol_count' here
18272 (new_itemsets): Allocate `shift_symbol' here.
18273 (allocate_itemsets): symbol_count includes useless nonterminals.
18274 Make room for them.

18286 * src/gram.c, src/gram.h (ritem_print): New.
18287 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
18288 (This useless function was defined only to work around VMS linkers
18289 that can't handle compilation units with variables only).
18290 * src/reduce.c (dump_grammar): Use it to trace the construction of
18293 2001-12-04 Paul Eggert <eggert@twinsun.com>
18295 * src/bison.simple (union yyalloc): Change member names
18296 to be the same as the stack names.
18297 (yyparse): yyptr is now union yyalloc *, not char *.
18298 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
18299 and may generate better code on some machines.
18300 (yystpcpy): Use prototype if __STDC__ is defined, not just
18301 if __cplusplus is defined.
18303 2001-11-30 Akim Demaille <akim@epita.fr>
18305 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
18306 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
18307 Gettext doesn't compile cleanly, and dies with -Werror.
18308 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
18309 Include WARNING_CFLAGS here.
18310 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
18311 before being defined.

18315 * lib/quotearg.h (quotearg_n, quotearg_n_style):
18316 First arg is int, not unsigned.

18318 (SIZE_MAX, UINT_MAX): New macros.
18319 (quotearg_n_options): Abort if N is negative.
18320 Avoid overflow check on hosts where size_t is 64 bits and int
18321 is 32 bits, as overflow is impossible there.
18322 Fix off-by-one typo that caused unnecessary reallocation.
18324 2001-11-29 Paul Eggert <eggert@twinsun.com>
18326 Name space cleanup in generated parser.
18328 * doc/bison.texinfo (Bison Parser): Discuss system headers
18329 and their effect on the user name space.
18331 * src/bison.simple:
18332 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
18333 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
18334 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
18336 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
18337 on user names when possible.
18339 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
18340 Simplify test for whather <alloca.h> exists.
18342 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
18344 (<stdio.h>): Include if YYDEBUG.
18346 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
18347 ! defined (yyoverflow) && ! defined (yymemcpy).
18349 (yymemcpy, yyparse): Rename local variables as needed so that
18350 they all begin with 'yy'.
18352 (yystrlen, yystpcpy): New functions.
18354 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
18357 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
18358 instead of relying on string.h functions. Use YYSTACK_ALLOC
18359 and YYSTACK_FREE instead of malloc and free.
18361 2001-11-30 Akim Demaille <akim@epita.fr>
18363 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
18364 before their first uses.

18374 if body instead of `;' to pacify GCC's warnings.
18376 2001-11-30 Akim Demaille <akim@epita.fr>
18378 Instead of mapping the LHS of unused rules to -1, keep the LHS
18379 valid, but flag the rules as invalid.
18381 * src/gram.h (rule_t): `useful' is a new member.
18382 * src/print.c (print_grammar): Adjust.
18383 * src/derives.c (set_derives): Likewise.
18384 * src/reader.c (packgram, reduce_output): Likewise.
18385 * src/reduce.c (reduce_grammar_tables): Likewise.
18386 * tests/reduce.at (Underivable Rules, Useless Rules): New.
18388 2001-11-30 Akim Demaille <akim@epita.fr>

18402 2001-11-30 Akim Demaille <akim@epita.fr>

18412 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
18413 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
18415 (union yyalloc): New type.
18416 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
18417 an arbitrary restriction on hosts where size_t is wider than int.
18419 (yyparse): Don't dump core if alloca or malloc fails; instead, report
18420 a parser stack overflow. Allocate just one block of memory for all
18421 three stacks, instead of allocating three blocks; this typically is
18422 faster and reduces fragmentation.
18424 Do not limit the number of items in the stack to a value that fits
18425 in 'int', as this is an arbitrary limit on hosts with 64-bit
18426 size_t and 32-bit int.
18428 2001-11-29 Marc Autret <autret_m@epita.fr>
18430 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
18431 of defining YYERROR_VERBOSE.
18432 [AT_DATA]: $4 is now out of C declarations in the prologue.
18434 2001-11-28 Marc Autret <autret_m@epita.fr>

18478 * src/closure.c (closure): `b' and `ruleno' denote the same value:
18481 2001-11-28 Akim Demaille <akim@epita.fr>
18483 * src/closure.c (closure): Instead of looping over word in array
18484 then bits in words, loop over bits in array.
18486 2001-11-28 Akim Demaille <akim@epita.fr>
18488 * src/closure.c (closure): No longer optimize the special case
18489 where all the bits of `ruleset[r]' are set to 0, to make the code

18504 * src/reduce.c (dump_grammar): Don't translate trace messages.
18506 2001-11-28 Akim Demaille <akim@epita.fr>
18508 * tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
18509 * src/reduce.c (reduce_grammar_tables): Do not free useless tags,

18513 2001-11-27 Paul Eggert <eggert@twinsun.com>
18515 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to

18599 * src/conflicts.c (conflicts_print): Don't complain at all when
18600 there are no reduce/reduce conflicts, and as many shift/reduce
18601 conflicts as expected.
18602 * tests/regression.at (%expect right): Adjust.
18604 2001-11-23 Akim Demaille <akim@epita.fr>

18625 2001-11-23 Akim Demaille <akim@epita.fr>
18627 Attaching lineno to buckets is stupid, since only one copy of each

20231 * src/conflicts.c (conflict_report): Be sure not to append to res
20232 between two calls, which could happen if both first sprintf were
20233 skipped, but not the first cp += strlen.
20235 2001-02-08 Akim Demaille <akim@epita.fr>
20237 * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
20238 New, from fileutils 4.0.37.
20239 * configure.in: Require Autoconf 2.49c. I took some time before
20240 making this decision. This is the only way out for portability
20241 issues in Bison, it would mean way too much duplicate effort to
20242 import in Bison features implemented in 2.49c since 2.13.
20243 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
20245 2001-02-02 Akim Demaille <akim@epita.fr>

20262 * src/lex.h: Rename all the tokens:
20263 s/\bENDFILE\b/tok_eof/g;
20264 s/\bIDENTIFIER\b/tok_identifier/g;
20266 Let them be enums, not #define, to ease debugging.

20274 2001-01-18 Akim Demaille <akim@epita.fr>
20276 Since we now use obstacks, more % directives can be enabled.
20278 * src/lex.c (percent_table): Also accept `%yacc',
20279 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and

20282 instead of returning a token.

20284 * src/reader.c (read_declarations): Adjust.
20285 * src/files.c (open_files): Don't call `compute_base_names', don't

20289 * src/output.c (output_headers): Document the fact that this patch
20290 introduces a guaranteed SEGV for semantic parsers.
20291 * doc/bison.texinfo: Document them.
20292 * tests/suite.at: Exercise these %options.
20294 2000-12-20 Akim Demaille <akim@epita.fr>

20304 (obstack_fgrow4): New.
20306 2000-12-20 Akim Demaille <akim@epita.fr>
20308 * src/files.c (open_files): Fix the computation of short_base_name
20309 in the case of `-o foo.tab.c'.

20317 2000-12-20 Akim Demaille <akim@epita.fr>
20319 * src/files.c (open_files): Actually the `.output' file is based

20359 (obstack_grow_string): this.
20360 * src/output.c (output_parser): Recognize `%% actions' instead of
20362 * src/bison.s1: s/$/%% actions/.
20363 * src/bison.hairy: Likewise.
20365 2000-12-19 Akim Demaille <akim@epita.fr>
20367 * src/output.c (output_parser): Compute the `#line' lines when
20369 * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.

20392 2000-12-19 Akim Demaille <akim@epita.fr>
20394 * src/files.c (open_files): Yipee! We no longer need all the code

20399 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

20424 2000-11-17 Akim Demaille <akim@epita.fr>
20426 * lib/obstack.h: Formatting changes.
20427 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
20428 prevents type checking.
20429 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
20430 cast the value to (void *): assigning a `foo *' to a `void *'

20452 Use them to declare the variables which are global or local to
20455 2000-11-17 Akim Demaille <akim@epita.fr>
20457 * acconfig.h: Remove, no longer used.
20459 2000-11-07 Akim Demaille <akim@epita.fr>
20461 * src: s/Copyright (C)/Copyright/g.
20463 2000-11-07 Akim Demaille <akim@epita.fr>
20465 * src/reader.c (reader): #define YYLSP_NEEDED to 1 instead of just
20467 * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.
20469 2000-11-07 Akim Demaille <akim@epita.fr>
20471 * src/bison.s1 (YYLEX): Use #if instead of #ifdef.

20477 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
20478 argument `data' for consistency with the prototypes.
20479 Qualify it `const'.
20480 (obstack_copy, obstack_copy0): Rename the second argument as
20481 `address' for consistency. Qualify it `const'.
20482 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
20483 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
20484 `const' their input argument (`data' or `address').
20485 Adjust the corresponding macros to include `const' in casts.
20487 2000-11-03 Akim Demaille <akim@epita.fr>
20489 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
20490 s/PFILE1/BISON_HAIRY/.
20491 Adjust dependencies.
20493 2000-11-03 Akim Demaille <akim@epita.fr>
20495 For some reason, this was not applied.
20497 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
20498 `unlink': it's no longer used.
20500 2000-11-03 Akim Demaille <akim@epita.fr>
20502 * src/files.c (skeleton_find): New function, eved out of...

20507 Don't use `atexit'.
20509 * src/files.c (obstack_save): New function.
20510 (done): Rename as...
20511 (output_files): this.
20512 Use `obstack_save'.
20513 * src/main.c (main): Don't use `atexit' to register `done', since
20514 it no longer has to remove tmp files, just call `output_files'
20515 when there are no errors.
20517 2000-11-02 Akim Demaille <akim@epita.fr>
20519 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
20520 `unlink': it's no longer used.
20521 * src/files.h: Formatting changes.
20523 2000-11-02 Akim Demaille <akim@epita.fr>
20525 Remove the last uses of mktemp and unlink/delete.
20527 * src/files.c (fdefines, ftable): Removed.
20528 (defines_ostack, table_obstack): New.
20529 Adjust dependencies of the former into uses of the latter.
20530 * src/output.c (output_short_or_char_table, output_short_table):
20531 Convert to using obstacks.

20543 * src/files.c (fattrs): Remove.
20544 (attrs_obstack): New.

20556 Adjust all dependencies.
20558 2000-10-20 Akim Demaille <akim@epita.fr>
20560 * lib/quote.h (PARAMS): New macro. Use it.
20562 2000-10-16 Akim Demaille <akim@epita.fr>

20585 2000-10-16 Akim Demaille <akim@epita.fr>
20587 * src/reader.c (copy_comment2): Expect the input stream to be on
20588 the `/' which is suspected to open a comment, instead of being
20589 called after `//' or `/*' was read.
20590 (copy_comment, copy_definition, parse_union_decl, copy_action)
20591 (copy_guard): Adjust.
20593 2000-10-16 Akim Demaille <akim@epita.fr>
20595 * src/reader.c (parse_expect_decl): Use `skip_white_space' and
20596 `read_signed_integer'.
20598 2000-10-16 Akim Demaille <akim@epita.fr>
20600 * src/reader.c (copy_dollar): New function.
20601 (copy_guard, copy_action): Use it.
20603 2000-10-16 Akim Demaille <akim@epita.fr>
20605 * lib/quote.h, lib/quote.c, lib/quotearg.h, lib/quotearg.c:
20606 * m4/prereq.m4, m4/c-bs-a.m4, m4/mbstate.m4:
20607 New files, from Fileutils 4.0.27.
20608 * src/main.c (printable_version): Remove.
20609 * src/lex.c, src/reader.c: Use `quote'.
20611 2000-10-04 Akim Demaille <akim@epita.fr>
20613 * lib/error.c, lib/error.h: New files, needed by xmalloc.c.
20615 2000-10-04 Akim Demaille <akim@epita.fr>
20617 * doc/bison.texinfo: Various typos spotted by Neil Booth.
20619 2000-10-04 Akim Demaille <akim@epita.fr>
20621 When a literal string is used to define two different tokens,
20622 `bison -v' segfaults.
20623 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
20625 * tests/regression.m4: New file.
20626 Include the core of the sample provided by Piotr Gackiewicz.
20627 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
20630 2000-10-04 Akim Demaille <akim@epita.fr>
20632 * src/reader.c (parse_expect_decl): Keep `count' within the size
20636 2000-10-02 Paul Eggert <eggert@twinsun.com>
20638 * bison.s1 (yyparse): Assign the default value
20639 unconditionally, to avoid a GCC warning and make the parser a
20642 2000-10-02 Akim Demaille <akim@epita.fr>
20644 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
20647 2000-10-02 Akim Demaille <akim@epita.fr>
20649 * src/derives.c, src/print.c, src/reduce.c: To ease the
20650 translation, move some `\n' out of the translated strings.
20652 2000-10-02 Akim Demaille <akim@epita.fr>
20654 The location tracking mechanism is precious for parse error
20655 messages. Nevertheless, it is enabled only when `@n' is used in
20656 the grammar, which is a different issue (you can use it in error
20657 message, but not in the grammar per se). Therefore, there should
20658 be another means to enable it.
20660 * src/getargs.c (getargs): Support `--locations'.
20661 (usage): Report it.
20662 * src/getargs.h (locationsflag): Export it.
20663 * src/lex.c (percent_table): Support `%locations'.
20664 * src/reader.c (yylsp_needed): Remove this variable, now replaced
20665 with `locationsflag'.
20666 * doc/bison.texinfo: Document `--locations' and `%locations'.
20668 * tests/calc.m4: Test it.
20670 For regularity of the names, replace each
20671 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
20672 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
20673 In addition replace each `flag' with `_flag'.
20675 2000-10-02 Akim Demaille <akim@epita.fr>
20677 Also test parse error messages, including with YYERROR_VERBOSE.
20679 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
20681 Use it to check the computations.
20682 Use it to check `nonassoc' is honored.
20683 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
20684 `--yyerror-verbose'.
20685 (_AT_CHECK_CALC): Adjust to this option.
20686 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
20688 2000-10-02 Akim Demaille <akim@epita.fr>
20690 Test also `--verbose', `--defines' and `--name-prefix'. Testing
20691 the latter demonstrates a flaw in the handling of non debugging
20692 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
20693 was used in order to simplify:
20709 unfortunately this leads to a CPP conflict when
20710 `--name-prefix=foo' is used since it produces `#define yydebug
20713 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
20714 (YYDPRINTF): New macro.
20716 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
20718 Also test `--verbose', `--defines' and `--name-prefix'.
20720 2000-10-02 Akim Demaille <akim@epita.fr>
20722 Improve the readability of the produced parsers.
20724 * src/bison.s1: Formatting changes.
20725 Improve the comment related to the `$' mark.
20726 (yydefault): Don't fall through to `yyresume': `goto' there.
20727 * src/output.c (output_parser): When the `$' is met, skip the end
20729 New variable, `number_of_dollar_signs', to check there's exactly
20730 one `$' in the parser skeleton.
20732 2000-10-02 Akim Demaille <akim@epita.fr>
20734 * lib/xstrdup.c: New file, from the fileutils.
20735 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
20736 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
20737 instead of strlen + xmalloc + strcpy.
20738 * src/symtab.c (copys): Remove, use xstrdup instead.
20740 2000-10-02 Akim Demaille <akim@epita.fr>

20761 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
20762 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
20763 difficult and introduced a lot of core dump. It turns out that
20764 Bison used an implementation of `xmalloc' based on `calloc', and
20765 at various places it does depend upon the initialization to 0. I
20766 have not tried to isolate the pertinent places, and all the former
20767 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
20768 someone should address this issue.
20770 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
20771 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

20867 output_short_table.
20869 2000-10-02 Akim Demaille <akim@epita.fr>
20871 `user_toknums' is output as a `short[]' in `output.c', while it is
20872 defined as a `int[]' in `reader.c'. For consistency with the
20873 other output tables, `user_toknums' is now defined as a table of

20917 * src/system.h: Define PARAMS.

21138 Change the handling of @s so that they behave exactly like $s.
21139 There is now a pseudo variable @$ (readble and writable), location
21140 of the lhs of the rule (by default ranging from the location of

21142 or, if the rhs is empty, YYLLOC).

21149 same way you stack YYVAL.

21177 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

21904 (parse_percent_token): Added % declarations as another
21905 way to specify the flags -n, -l, and -r. Also added hooks for
21906 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
21907 major changes to files.c.
21908 (lex) Retain in the incoming stream a character following
