181 Fix portability issue in the test suite.
182 * tests/local.at (AT_MATCHES_CHECK): New.

216 Makefile properly updates atconfig when needed.
218 2008-12-07 Di-an Jan <dianj@freeshell.org>
220 Implement the FIXME that ends an user action with a semicolon
221 if it seems necessary.
222 * src/scan-code.l (flex rules section): Flag cpp directive from
223 any `#' to the first unescaped end-of-line. Semicolon is not
224 needed after `;', `{', '}', or cpp directives and is needed after
225 any other token (whitespaces and comments have no effect).

256 2008-12-01 Akim Demaille <demaille@gostai.com>
258 Use b4_symbol for printers and destructors everywhere.
259 * data/bison.m4 (b4_symbol_action_location): New.
260 * data/c.m4 (b4_symbol_actions): Remove.
261 Adjust all callers to use by b4_symbol_foreach and the corresponding
262 b4_symbol_printer/destructor macro.
263 * data/glr.cc: Adjust.
264 * data/lalr1.java: Adjust the %destructor sanity check.
265 * src/output.c (symbol_code_props_output): Remove, we no longer
266 need the b4_symbol_printers/destructors tables.
268 2008-12-01 Akim Demaille <demaille@gostai.com>
271 * data/lalr1.cc, data/bison.m4 (b4_symbol_action): Use
274 2008-12-01 Akim Demaille <demaille@gostai.com>

279 (b4_symbol_case_, b4_symbol_foreach, b4_type_action_)
280 (b4_type_foreach): Move to...
281 * data/bison.m4: Here.
282 * data/lalr1.cc (b4_symbol_action): Specialize for C++: use
283 b4_symbol_value_template instead of b4_symbol_value.
285 2008-12-01 Akim Demaille <demaille@gostai.com>
287 b4_symbol/type_foreach.
288 * data/lalr1.cc (b4_symbol_foreach, b4_type_foreach): New.
291 2008-12-01 Akim Demaille <demaille@gostai.com>
293 Use the symbol properties to output the printer/destructor for lalr1.cc.
294 Instead of defining complex list of tuples to define various
295 properties of the symbols, we now prefer to define symbols as
296 "structs" in m4: using the symbol key (its number), and the
297 property name, b4_symbol gives it value. Use this to handle
298 destructors and printers.
300 * src/output.c (CODE_PROP): New.
301 (prepare_symbol_definitions): Use it to define the printer and
302 destructor related attributes of the symbols.
303 * data/lalr1.cc (b4_symbol_actions): Rename as...
304 (b4_symbol_action): this.
305 Use b4_symbol instead of 6 arguments.

317 Remove spurious empty line before syncline.
318 * data/bison.m4 (b4_syncline): Don't output an empty line before
321 2008-11-26 Akim Demaille <demaille@gostai.com>
323 Convert lib/Makefile.am into lib/local.mk.
324 The real problem is rather gnulib.mk, which itself is extracted
325 from a Makefile.am that gnulib expects to the "recursive". The
326 tool prefix-gnulib-mk converts such a gnulib.mk to be
327 non-recursive. Also, some AC_SUBST variables need to be adjusted.
329 * etc/prefix-gnulib-mk: New.
330 * bootstrap (slurp): Use it to convert further gnulib.mk.
331 No longer try to avoid re-creation of lib/gnulib.mk as the changes
333 * lib/Makefile.am: Rename as...
334 * lib/local.mk: this.
335 Adjust to be prefixed.
336 * Makefile.am, configure.ac: Adjust.
337 * src/local.mk (AM_CPPFLAGS): Extend it, don't define it.

348 Use b4_parser_tables_define in glr.cc.
349 * data/glr.c: Use b4_parser_tables_define instead of defining the
350 (deterministic integral) tables by hand.
352 2008-11-26 Akim Demaille <demaille@gostai.com>
354 Use b4_parser_tables_define in Java.

377 (yyrline_): Move the comment where it is actually used.
378 * data/yacc.c: Adjust.
379 (yyrline): Use b4_integral_parser_table_define.
381 2008-11-26 Akim Demaille <demaille@gostai.com>
384 * src/parse-gram.h, src/parse-gram.c: Regen.
386 2008-11-26 Akim Demaille <demaille@gostai.com>
388 Factor the generation of the (integral) tables bw yacc.c and lalr1.cc.

391 Update the comment for yytable during the flight.
392 (b4_tables_declare, b4_tables_define): New.
393 * data/lalr1.cc: Use them.
394 * data/c.m4 (b4_table_define): New.
395 * data/yacc.c: Use b4_tables_define instead of output the tables
397 * tests/regression.at (Web2c Actions): Adjust the expected output,
398 the order of the tables changed.
400 2008-11-26 Akim Demaille <demaille@gostai.com>
402 Get rid of (yy)rhs and (yy)prhs.
403 These tables are no longer needed in the parsers, and they don't seem to
404 be useful. They are not documented either.
406 * src/output.c (prepare_rules): Get rid of rhs and prhs.
407 Adjust the computation of (yy)r2.
409 2008-11-26 Akim Demaille <demaille@gostai.com>
411 Rule length is unsigned.
412 * src/gram.h, src/gram.c (rule_rhs_length): Return a size_t.
414 2008-11-26 Akim Demaille <demaille@gostai.com>
416 Get rid of lalr1-split.cc.
417 It was no longer maintainer.
419 * data/lalr1-split.cc: Remove.
420 * etc/bench.pl.in (bench_fusion_parser): Remove.
423 2008-11-26 Akim Demaille <demaille@gostai.com>
425 Use yy* consistently.
426 * data/glr.c: Now that yyrhs no longer exists as a global
427 variable, rename local "rhs" variables into "yyrhs" for
430 2008-11-25 Akim Demaille <demaille@gostai.com>
432 Get rid of yyrhs and yyprhs in glr.c.
433 * data/glr.c (yyrhs, yyprhs): Remove.
434 Instead, use the state stack and yystos.
436 2008-11-25 Akim Demaille <demaille@gostai.com>
439 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): If glr, declare it
440 as an Autotest keyword.
442 2008-11-25 Akim Demaille <demaille@gostai.com>
444 Prefer TESTSUITE_FLAGS.
445 TESTSUITEFLAGS is barely readable.
447 * tests/local.mk (TESTSUITE_FLAGS): Default to $(TESTSUITEFLAGS)
448 for backward compatibility.
449 Use the former instead of the latter.
451 2008-11-25 Akim Demaille <demaille@gostai.com>
453 Get rid of yyrhs and yyprhs in larl1.java.
454 * data/lalr1.java (yyrhs_, yyprhs_): Remove.
455 (yy_reduce_print): Rather, use yystos_ and the state stack.
457 2008-11-25 Akim Demaille <demaille@gostai.com>
461 2008-11-25 Akim Demaille <demaille@gostai.com>
463 Get rid of yyrhs and yyprhs in yacc.c.
464 They were used to get the symbol types, given a rule number, when
465 displaying the top of the stack before a reduction. But the
466 symbol type is available from the state stack. This has two be
467 benefits: two tables less in the parser (making it smaller), and a
468 more consistent use of the three stacks which will help to fuse
471 * data/yacc.c (yyprhs, yyrhs): Remove.
472 (YY_REDUCE_PRINT): Pass yyssp to yy_reduce_print.
473 (yy_reduce_print): Take yyssp as argument.
474 Use it, together with yystos, to get the symbol type.
475 * tests/regression.at (Web2c Report): Remove these tables from the
478 2008-11-25 Akim Demaille <demaille@gostai.com>
481 The point is to factor the generation of the tables across skeletons.
482 This is language dependant.
484 * data/c.m4 (b4_comment_): New.
485 Should be usable to define how to generate tables independently of
488 (b4_comment): Bounce to b4_c_comment.
489 Now support $2 = [PREFIX] for indentation.
490 * data/lalr1.cc (b4_table_declare): Don't output a comment if
492 Indent it properly when there is one.
493 Output the ending semicolon.
494 (b4_table_define): Space changes.
495 Output the ending semicolon.
496 (b4_tables_map): New.
497 Use it twice instead of declaring and defining the (integral)

662 2008-11-15 Akim Demaille <demaille@gostai.com>
664 Support parametric types.
666 There are two issues to handle: first scanning nested angle
667 bracket pairs to support types such as std::pair< std::string,
668 std::list<std::string> > >.
670 Another issue is to address idiosyncracies of C++: do not glue two
671 closing angle brackets together (otherwise it's operator>>), and
672 avoid sticking blindly a TYPE to the opening <, as it can result
673 in '<:' which is a digraph for '['.
675 * src/scan-gram.l (brace_level): Rename as...
678 Implement support for complex tags.
681 * data/lalr1.cc (b4_symbol_value, b4_symbol_value_template)

684 * src/parse-gram.y (TYPE, TYPE_TAG_ANY, TYPE_TAG_NONE, type.opt):
686 (TAG, TAG_ANY, TAG_NONE, tag.opt): these.
687 * tests/c++.at: Test parametric types.
689 2008-11-15 Akim Demaille <akim@betelgeuse.gostai.ensta.fr>
692 This is not sufficient, but we test at least that the make_SYMBOL
693 interface is not affected by token.prefix. A more general test
694 will be implemented when the support of token.prefix is generalized

772 It does not work, and I don't know how it was supposed to work: it
773 seems to be looking for sources in the build tree. I just moved
774 it at a better place, fixing it is still required.

797 part of this very Makefile.
798 * Makefile.am, configure.ac: Adjust.
799 * src/scan-code-c.c, src/scan-code.l: We can no longer rely on
800 include "..." to find files "here": we are no longer in src/, so
801 qualify the includes with src/.
802 * doc/Makefile.am (PREPATH): No longer include the top_builddir

853 Provide convenience constructors for locations and positions.
854 * data/location.cc (position::position): Accept file, line and
855 column as arguments with default values.
856 Always qualify initial line and column literals as unsigned.
857 (location::location): Provide convenience constructors.
859 2008-11-15 Akim Demaille <demaille@gostai.com>
861 Instead of using make_symbol<TOK_FOO>, generate make_FOO for each
863 Using template buys us nothing, and makes it uselessly complex to
864 construct a symbol. Besides, it could not be generalized to other
865 languages, while make_FOO would work in C/Java etc.
867 * data/lalr1.cc (b4_symbol_): New.
869 (b4_symbol_constructor_declaration_)
870 (b4_symbol_constructor_definition_): Instead of generating
871 specializations of an overloaded template function, just generate
872 several functions whose names are forged from the token names
873 without the token.prefix.
874 (b4_symbol_constructor_declarations): Generate them for all the
875 symbols, not just by class of symbol type, now that instead of
876 specializing a function template by the token, we generate a
877 function named after the token.
878 (b4_symbol_constructor_specialization_)
879 (b4_symbol_constructor_specializations): Remove.
880 * etc/bench.pl.in: Adjust to this new API.
882 2008-11-13 Akim Demaille <demaille@gostai.com>
884 %define token.prefix.
885 Provide a means to add a prefix to the name of the tokens as
886 output in the generated files. Because of name clashes, it is
887 good to have such a prefix such as TOK_ that protects from names
888 such as EOF, FILE etc. But it clutters the grammar itself.
890 * data/bison.m4 (token.prefix): Empty by default.
891 * data/c.m4 (b4_token_enum, b4_token_define): Use it.
892 * data/lalr1.cc (b4_symbol): Ditto.
894 2008-11-13 Akim Demaille <demaille@gostai.com>
896 Compute at M4 time some of the subtractions.
897 * data/lalr1.cc (b4_subtract): New.
898 (b4_rhs_data): Use it.
900 2008-11-13 Akim Demaille <demaille@gostai.com>
903 This allows the user to get the type of a token returned by yylex.
905 * data/lalr1.cc (symbol::token): New.
906 (yytoknum_): Define when %define lex_symbol, independently of
908 (yytoken_number_): Move into...
909 (symbol::token): here, since that's the only use.
910 The other one is YYPRINT which was not officially supported
911 by lalr1.cc, and anyway it did not work since YYPRINT uses this
912 array under a different name (yytoknum).
914 2008-11-13 Akim Demaille <demaille@gostai.com>
917 * TODO (YYERRCODE): Mention the case of $undef.

924 2008-11-13 Akim Demaille <demaille@gostai.com>

928 yytranslate and yytoknum tables.
930 2008-11-13 Akim Demaille <demaille@gostai.com>
932 Define make_symbol in the header.
933 To reach good performances these functions should be inlined (yet
934 this is to measure precisely). To this end they must be available
937 * data/lalr1.cc (b4_symbol_constructor_definition_): Qualify
938 location_type with the class name.
939 Since will now be output in the header, declare "inline".
940 No longer use b4_symbol_constructor_specializations, but
941 b4_symbol_constructor_definitions in the header.
942 Don't call it in the *.cc file.
944 2008-11-13 Akim Demaille <demaille@gostai.com>
946 Define yytranslate in the header for lex_symbol.
947 * data/lalr1.cc: Move the invocation of b4_yytranslate_definition
948 into the header file when using %define lex_symbol.
949 (yytranslate_): Declare inline.
951 2008-11-13 Akim Demaille <demaille@gostai.com>
953 Define the constructors of symbol_type in
954 b4_symbol_constructor_definitions.
955 The constructors are called by the make_symbol functions, which a
956 forthcoming patch will move elsewhere. Hence the interest of
957 putting them together.
959 The stack_symbol_type does not need to be moved, it is used only
962 * data/lalr1.cc: Move symbol_type and symbol_base_type
964 (b4_symbol_constructor_definitions): here.
967 2008-11-13 Akim Demaille <demaille@gostai.com>
969 Make it easier to move the definition of yytranslate_.
970 Forthcoming changes will make it possible to use yytranslate_
971 from outside the parser implementation file.
973 * data/lalr1.cc (b4_yytranslate_definition): New.
976 2008-11-13 Akim Demaille <demaille@gostai.com>
978 Remove useless class specification.
979 * data/lalr1.cc (b4_symbol_constructor_specialization_): No need
980 to refer to the class name to use a type defined by the class for
981 arguments of member functions.
983 2008-11-13 Akim Demaille <demaille@gostai.com>
985 Finer input type for yytranslate.
986 This patch is debatable: the tradition expects yylex to return an int
987 which happens to correspond to token_number (which is an enum). This
988 allows for instance to return characters (such as '*' etc.). But this
989 goes against the stronger typing I am trying to have with the new
990 lex interface which return a symbol_type. So in this case, feed
991 yytranslate_ with a token_type.
993 * data/lalr1.cc (yytranslate_): When in %define lex-symbol,
996 2008-11-13 Akim Demaille <demaille@gostai.com>
998 Honor lex-params in %define lex_symbol mode.
999 * data/lalr1.cc: Use b4_lex_param.
1001 2008-11-13 Akim Demaille <demaille@gostai.com>
1004 * src/output.c (symbol_definitions_output): Rename symbol
1005 attributes type_name and has_type_name as type and has_type.
1006 * data/lalr1.cc: Adjust uses.
1008 2008-11-13 Akim Demaille <demaille@gostai.com>
1010 Use b4_type_names for the union type.
1011 The union used to compute the size of the variant used to iterate
1012 over the type of all the symbols, with a lot of redundancy. Now
1013 iterate over the lists of symbols having the same type-name.
1015 * data/lalr1.cc (b4_char_sizeof_): New.
1016 (b4_char_sizeof): Use it.
1017 Adjust to be called with a list of numbers instead of a single
1019 Adjust its caller for new-line issues.
1021 2008-11-13 Akim Demaille <demaille@gostai.com>
1023 Define the "identifier" of a symbol.
1024 Symbols may have several string representations, for instance if
1025 they have an alias. What I call its "id" is a string that can be
1026 used as an identifier. May not exist.
1028 Currently the symbols which have the "tag_is_id" flag set are
1029 those that don't have an alias. Look harder for the id.
1031 * src/output.c (is_identifier): Move to...
1032 * src/symtab.c (is_identifier): here.
1033 * src/symtab.h, src/symtab.c (symbol_id_get): New.
1034 * src/output.c (symbol_definitions_output): Use it to define "id"
1036 Remove the definition of "tag_is_id".
1037 * data/lalr1.cc: Use the "id" and "has_id" whereever "tag" and
1038 "tag_is_id" were used to produce code.
1039 We still use "tag" for documentation.
1041 2008-11-11 Akim Demaille <demaille@gostai.com>
1043 Locations are no longer required by lalr1.cc.
1044 * data/lalr1.cc (_b4_args, b4_args): New.
1045 Adjust all uses of locations to make them optional.
1046 * tests/c++.at (AT_CHECK_VARIANTS): No longer use the locations.
1047 (AT_CHECK_NAMESPACE): Check the use of locations.
1048 * tests/calc.at (_AT_DATA_CALC_Y): Adjust to be usable with or
1049 without locations with lalr1.cc.
1051 * tests/output.at: Check lalr1.cc with and without location
1053 * tests/regression.at (_AT_DATA_EXPECT2_Y, _AT_DATA_DANCER_Y):
1054 Don't use locations.

1059 * tests/local.at (AT_FULL_COMPILE): New.

1064 Support parens in calc++.
1065 * doc/bison.texinfo (Calc++ Scanner, Calc++ Parser): Support parens.

1086 2008-11-11 Akim Demaille <demaille@gostai.com>
1088 Support i18n of the parse error messages.
1089 * TODO (lalr1.cc/I18n): Remove.
1090 * data/lalr1.cc (yysyntax_error_): Support the translation of the
1091 error messages, as done in yacc.c.
1092 Stay within the yy* pseudo namespace.

1101 Make it possible to return a symbol_type from yylex.

1139 Let yytranslate handle the eof case.
1140 * data/lalr1.cc (yytranslate_): Handle the EOF case.
1142 No longer expect yychar to be equal to yyeof_, rather, test the
1143 lookahead's (translated) kind.
1145 2008-11-11 Akim Demaille <demaille@gostai.com>
1147 yychar cannot be empty in yyerrlab.
1148 * TODO (yychar == yyempty_): New.
1149 * data/lalr1.cc: Remove the handling of this case.
1150 This eases forthcoming changes related to yychar and yytranslate.

1154 Bench: syntactic sugar for %define/#define.

1162 Less memory pressure on the "list" bench.
1163 * etc/bench.pl.in (generate_grammar_list): Do not accumulate all
1164 the values, to limit memory pressure.
1166 2008-11-11 Akim Demaille <demaille@gostai.com>
1168 Introduce make_symbol.
1169 make_symbol provides a means to construct a full symbol (kind,
1170 value, location) in a single shot. It is meant to be a Symbol
1171 constructor, parameterized by the symbol kind so that overloading
1172 would prevent incorrect kind/value pairs. Unfortunately
1173 parameterized constructors do not work well in C++ (unless the
1174 parameter also appears as an argument, which is not acceptable),
1175 hence the use of a function instead of a constructor.
1177 * data/lalr1.cc (b4_symbol_constructor_declaration_)
1178 (b4_symbol_constructor_declarations)
1179 (b4_symbol_constructor_specialization_)
1180 (b4_symbol_constructor_specializations)
1181 (b4_symbol_constructor_definition_)
1182 (b4_symbol_constructor_definitions): New.
1183 Use them where appropriate to generate declaration, declaration of
1184 the specializations, and implementations of the templated
1185 overloaded function "make_symbol".
1186 (variant::variant): Always define a default ctor.
1187 Also provide a copy ctor.
1188 (symbol_base_type, symbol_type): New ctor overloads for value-less
1190 (symbol_type): Now public, so that functions such as yylex can use

1195 Inform m4 whether a tag is a valid id.
1196 * src/output.c (is_identifier): New.
1197 (symbol_definitions_output): Use it to define tag_is_id.
1198 But maybe this should be done at m4 level?
1200 2008-11-11 Akim Demaille <demaille@gostai.com>
1202 Test 214 was failing: it greps with a pattern containing [ ]*
1203 which obviously meant to catch spaces and tabs, but contained only
1204 spaces. Tabulations in sources are a nuisance, so to simplify the
1205 matter, get rid of all the tabulations in the Java sources. The
1206 other skeletons will be treated equally later.
1208 * data/java.m4, data/lalr1.java: Untabify.
1209 * tests/java.at: Simplify AT_CHECK_JAVA_GREP invocations:
1210 tabulations are no longer generated.

1247 the other skeletons.

1313 More information about the symbols.
1314 * src/output.c (type_names_output): Document all the symbols,
1315 including those that don't have a type-name.
1316 (symbol_definitions_output): Define "is_token" and

1325 2008-11-10 Akim Demaille <demaille@gostai.com>
1327 Make parser::yytranslate static.

1338 * data/lalr1.cc: Don't indent before rule and symbol actions, as
1339 they can be empty, and anyway this incorrectly indents the first

1346 2008-11-10 Akim Demaille <demaille@gostai.com>

1388 2008-11-10 Akim Demaille <demaille@gostai.com>
1390 Change the handling of the symbols in the skeletons.
1391 Before we were using tables which lines were the symbols and which
1392 columns were things like number, tag, type-name etc. It is was
1393 difficult to extend: each time a column was added, all the numbers had
1394 to be updated (you asked for colon $2, not for "tag"). Also, it was
1395 hard to filter these tables when only a subset of the symbols (say the
1396 tokens, or the nterms, or the tokens that have and external number
1397 *and* a type-name) was of interest.
1399 Now instead of monolithic tables, we define one macro per cell. For
1400 instance "b4_symbol(0, tag)" is a macro name which contents is
1401 self-decriptive. The macro "b4_symbol" provides easier access to
1404 * src/output.c (type_names_output): Remove.
1405 (symbol_numbers_output, symbol_definitions_output): New.
1406 (muscles_output): Call them.

1446 Use it with and without %define assert.
1448 2008-11-10 Akim Demaille <demaille@gostai.com>
1450 Add %precedence support.
1451 Unfortunately it is not possible to reuse the %prec directive. This
1452 is because to please POSIX, we do not require to end the rules with a
1453 semicolon. As a result,
1457 is ambiguous: either a rule which precedence is that of baz, or a rule,
1458 and then a declaration of the precedence of the token baz.
1460 * doc/bison.texinfo: Document %precedence.
1461 (Precedence Only): New.
1462 * src/assoc.h, src/assoc.c (precedence_assoc): New.

1588 Rely on the state stack to display reduction traces.
1589 To display rhs symbols before a reduction, we used information
1590 about the rule reduced, which required the tables yyrhs and
1591 yyprhs. Now use rely only on the state stack to get the same

1718 2008-11-07 Akim Demaille <demaille@gostai.com>
1720 Add "%define assert" to variants.
1721 This is used to help the user catch cases where some value gets
1722 ovewritten by a new one. This should not happen, as this will
1725 Unfortunately this uncovered a bug in the C++ parser itself: the
1726 lookahead value was not destroyed between two calls to yylex. For
1727 instance if the previous lookahead was a std::string, and then an int,
1728 then the value of the std::string was correctly taken (i.e., the
1729 lookahead was now an empty string), but std::string structure itself
1732 This is now done in variant::build(other&) (which is used to take the
1733 value of the lookahead): other is not only stolen from its value, it
1734 is also destroyed. This incurs a new performance penalty of a few
1735 percent, and union becomes faster again.
1737 * data/lalr1-fusion.cc (variant::build(other&)): Destroy other.

2014 2008-11-03 Akim Demaille <demaille@gostai.com>
2016 Fuse the three stacks into a single one.
2018 In order to make it easy to perform benchmarks to ensure that
2019 there are no performance loss, lalr1.cc is forked into
2020 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
2023 Meanwhile, to make sure that lalr1-fusion.cc is correctly
2024 exercized by the test suite, the user must install a symbolic link
2025 from lalr1.cc to it.
2027 Instead of having three stacks (state, value, location), use a
2028 stack of triples. This considerably simplifies the code (and it
2029 will be easier not to require locations as currently does the C++
2030 parser), and also gives a 10% speedup according to
2031 etc/bench (probably mainly since memory allocation is done once
2032 instead of three times).
2034 Another motivation is to make it easier to destruct properly
2035 semantic values: now that they are bound to their state (hence
2036 symbol type) it will be easier to call the appropriate destructor.
2038 These changes should probably benefit the C parser too.
2040 * data/lalr1.cc: Copy as...
2041 * data/lalr1-fusion.cc: this new file.
2042 (b4_rhs_value, b4_rhs_location): New definitions overriding those
2044 (state_stack_type, semantic_stack_type, location_stack_type)
2045 (yystate_stack_, yysemantic_stack_, yylocation_stack_): Remove.
2046 (data_type, stack_type, yystack_): New.
2047 (YYLLOC_DEFAULT, yypush_): Adjust.
2048 (yyerror_range): Now based on data_type, not location_type.
2050 2008-11-03 Akim Demaille <demaille@gostai.com>
2052 Push the state, value, and location at the same time.
2053 This is needed to prepare a forthcoming patch that fuses the three
2056 * data/lalr1.cc (parser::yypush_): New.
2057 (parser::yynewstate): Change the semantics: instead of arriving to
2058 this label when value and location have been pushed, but yystate
2059 is to be pushed on the state stack, now the three of them must
2060 have been pushed before. yystate still must be the new state.
2061 This allows to use yypush_ everywhere instead of individual
2062 handling of the stacks.
2064 2008-11-03 Akim Demaille <demaille@gostai.com>
2066 Prefer references to pointers.
2067 * data/lalr1.cc (b4_symbol_actions): New, overrides the default C
2068 definition to use references instead of pointers.
2069 (yy_symbol_value_print_, yy_symbol_print_, yydestruct_):
2070 Take the value and location as references.
2073 2008-11-03 Akim Demaille <demaille@gostai.com>
2075 stack::size instead of stack::height.
2076 * data/lalr1.cc (stack::height): Rename as...
2077 (stack::size): this.
2078 Fix the output type.
2081 2008-11-03 Akim Demaille <demaille@gostai.com>
2083 Use variants to support objects as semantic values.
2084 This patch was inspired by work by Michiel De Wilde. But he used
2085 Boost variants which (i) requires Boost on the user side, (ii) is
2086 slow, and (iii) has useless overhead (the parser knows the type of
2087 the semantic value there is no reason to duplicate this
2088 information as Boost.Variants do).
2090 This implementation reserves a buffer large enough to store the
2091 largest objects. yy::variant implements this buffer. It was
2092 implemented with Quentin Hocquet.
2094 * src/output.c (type_names_output): New.
2095 (output_skeleton): Invoke it.
2096 * data/c++.m4 (b4_variant_if): New.

2099 (b4_symbol_variant, _b4_char_sizeof_counter, _b4_char_sizeof_dummy)
2100 (b4_char_sizeof, yy::variant): New.
2101 (parser::parse): If variants are requested, define
2102 parser::union_type, parser::variant, change the definition of
2103 semantic_type, construct $$ before running the user action instead
2104 of performing a default $$ = $1.
2105 * examples/variant.yy: New.
2106 Based on an example by Michiel De Wilde.
2108 2008-11-03 Akim Demaille <demaille@gostai.com>
2110 Parameterize the extraction of semantic values.
2111 To make future changes easier, no longer rely on ".TYPE" being the
2112 way to get a semantic value.
2114 * data/c.m4 (b4_symbol_value): New.
2116 * data/c++.m4, data/yacc.c: Use it.
2117 * data/glr.c: Use b4_symbol_value.

2152 recommend it over %skeleton for now.
2153 (Bison Options): Likewise.

2225 Always put auxiliary code files in the same dir as other output files.
2226 * src/files.c (compute_file_name_parts): When the user specifies
2227 --output but not --file-prefix, extract the directory prefix from the
2228 file prefix not from the grammar file name. This affects the location
2229 of files like location.hh generated by the C++ skeleton. The includes

2494 * NEWS (2.3b+): Rename to...
2495 (?.?): ... this because we're dropping the "+" version naming scheme,
2496 but, in general, we still can't be sure of our next release name.
2497 * bootstrap: Add a quick hack to remove from .gitignore the
2498 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile
2499 entry. This should really be fixed in gnulib instead.
2500 * bootstrap.conf (gnulib_modules): Add gnumakefile.
2501 * configure.ac (AC_INIT): Set version name by invoking
2502 build-aux/git-version-gen.

2532 Fix some .gitignore and .cvsignore problems.
2533 * bootstrap (insert_sorted_if_absent): Replace all uses with...
2534 (insert_vc_ignore): ... this new function, which prepends `/' to all
2535 .gitignore entries before passing them to insert_sorted_if_absent.
2536 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that
2537 .cvsignore files are maintained even though Bison developers run
2538 bootstrap while using Git.
2539 * .cvsignore (*.patch *.log log patches applied): Remove, apparently
2542 * .gitignore (/*.patch *.log log patches applied): Remove, broken and
2543 unneeded. Reported by Eric Blake.

2558 * src/output.c (output_skeleton): For the m4 invocation, pass -dV as
2559 the first argument because it may become position-dependent, and unset
2560 POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
2561 Add comments explaining these issues in more detail.
2563 2008-07-14 Joel E. Denny <jdenny@ces.clemson.edu>

2596 2008-05-23 Joel E. Denny <jdenny@ces.clemson.edu>

2625 Revert prior patch, by working around autoconf regression.
2626 * tests/output.at (m4_expand): Add workaround for autoconf 2.62.
2627 ("Output file name: ("): Uncomment test.
2628 ("Output file name: )"): Likewise.
2629 Based on an idea from Noah Misch.
2631 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>

2645 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
2647 Update to the current gnulib CVS repository, and fix trigraph handling
2649 * bootstrap: Update gnulib CVS repository URL.
2650 (symlink_to_dir): Encapsulate the code that guarantees the destination
2651 directory exists into...
2652 (check_dst_dir): ... this new function, and...
2653 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
2654 fail when copying files into lib/uniwidth/.
2655 * src/output.c (prepare_symbols): When writing yytname muscles, where
2656 symbol names will be encoded in C-string literals, tell quotearg to
2657 escape trigraphs. This used to be the default in gnulib.
2658 * tests/regression.at (Token definitions): Because of the change in
2659 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
2660 escapes trigraphs in symbol names. Thus, yytname no longer has
2661 trigraphs unnecessarily doubly escaped. Update test case output.
2662 Extend test case to be sure Bison's own error messages will no longer
2663 have trigraphs in symbol names unnecessarily escaped once.
2665 2008-04-20 Joel E. Denny <jdenny@ces.clemson.edu>

2678 * doc/bison.texinfo (Bison Options): Reword -W entry a little for
2679 consistency. Update the -g and -x entries now that they take
2680 arguments. Use brackets to indicate optional arguments.
2681 * src/getargs.c (usage): Explain the relationship between arguments of
2682 long and short options more completely. Document --defines and -d
2683 separately since the former takes an argument but, for POSIX Yacc, the
2685 (short_options): Let -W take an optional argument like --warnings.

2703 Fix the handling of $opt which resulted in all the argument to be
2704 considered as optional.

3342 (C++ Bison Interface): Mention `%define namespace' instead of
3344 (Table of Symbols): Remove the `%define push_pull' entry. The %define
3346 * tests/c++.at (Relative namespace references): New test case.
3347 (Absolute namespace references): New test case.
3348 (Syntactically invalid namespace references): New test case.

3440 parsing requests here...
3441 * data/yacc.c: ... hack this to switch to push.c any time
3442 b4_use_push_pull_flag or the %define variable push_pull is set. This
3443 will go away when we mv push.c yacc.c.
3444 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
3445 push parsing is not supported since unused %define variables are

3656 Get rid of broken %no-parser, -n, and --no-parser implementation and
3658 * TODO: Don't mention them.
3659 * doc/bison.1: Likewise.
3660 * doc/bison.texinfo (Decl Summary): Likewise.
3661 (Bison Options): Likewise.
3662 (Option Cross Key): Likewise.
3663 * src/getargs.c (no_parser_flag): Remove global variable.
3664 (usage): Don't print description of -n and --no-parser.
3665 (long_options): Remove --no-parser entry here.
3666 (getargs): Remove -n case in the switch here.
3667 * src/getargs.h (no_parser_flag): Remove extern.
3668 * tests/regression.at (Web2c Actions): Remove comment that mentions
3671 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
3673 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
3674 name user variables starting with `yy'. Just pass NULL instead of a
3675 dummy local &yylval to yypush_parse.
3676 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
3679 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
3681 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
3682 true since it's then always used regardless of whether yyoverflow is
3683 defined. Reported by Christian Burger at
3684 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
3685 * THANKS: Add Christian Burger.
3687 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
3688 node names: say "Decl Summary" not "Bison Declaration Summary".
3690 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
3692 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
3693 determine whether this function has already complained about an invalid
3694 value for a %define boolean variable, don't check whether Bison has
3695 ever examined the value. As written, the check was a tautology.
3696 Instead, record and check for this complaint using a separate muscle.
3698 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
3700 Fix push parsing memory leak reported by Brandon Lucia at
3701 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
3702 * THANKS: Add Brandon Lucia.
3703 * data/push.c (yypstate_delete): Free the stack if it was reallocated
3704 but the parse never completed and thus freed it.
3705 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
3706 * tests/testsuite.at: Include push.at.
3707 * test/push.at: New.
3708 (Push Parsing: Memory Leak for Early Deletion): New test case.
3710 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
3712 Improve handling of multiple S/R conflicts in the same state and of S/R
3713 conflicts involving multiple reductions.
3714 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
3715 set for a state here or Bison will abort if it is reassigned on a
3716 later conflicted reduction in the same state.
3717 Similarly, don't finalize and assign the solved conflicts report here
3718 or it will be lost if it is reassigned on a later conflicted reduction
3720 (set_conflicts): Instead, assign them both here after all S/R conflicts
3721 in the state have been fully examined.
3722 * src/print.c (shift_set): Rename to...
3723 (no_reduce_set): ... this.
3724 (print_reductions): Update for rename, and add %nonassoc error action
3725 tokens to no_reduce_set so that, when printing the first remaining
3726 reduction on an error action token, the reduction is enclosed in
3728 (print_results): Update for rename.
3729 * tests/conflicts.at (Solved conflicts report for multiple reductions
3730 in a state): New test case.
3731 (%nonassoc error actions for multiple reductions in a state): New test
3734 * src/main.c (main): Don't depend on C99 features.
3736 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
3738 * build-aux/.cvsignore: Add compile.
3739 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
3742 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
3744 * bootstrap (slurp): Create target directories that don't exist.
3745 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
3747 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
3749 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
3751 * closure.c (closure): Likewise.
3752 * state.h (reductions): Comment sorting of rules.
3753 (state): Comment sorting of items.
3755 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
3757 Fix C++ test cases after recent Gnulib changes. Discussed starting at
3758 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
3759 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
3760 definition in order to avoid Gnulib headers since we don't use config.h
3762 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
3763 rather than AT_DATA so that config.h is included.
3765 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
3767 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
3768 instead of fprintf. Guard these functions with #if YYDEBUG instead of
3769 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
3770 and so that YYFPRINTF is guaranteed to be defined here.
3772 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
3774 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
3776 (muscle_percent_define_check_values): ... this more helpful function.
3777 Again, it's not used yet, but it will be.
3778 * src/muscle_tab.h: Likewise.
3780 Improve some comments in parser table construction.
3781 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
3782 (generate_states): Don't mention ruleset, which is internal to closure.
3783 * src/closure.c (closure): Explain sorting of core and itemset, which
3784 is required for this function to behave correctly.
3785 * src/closure.h (closure): Mention sorting.
3787 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
3789 * src/lalr.c (state_lookahead_tokens_count): For code readability,
3790 move the check for disabled transitions to an aver since conflict
3791 resolution hasn't happened yet.
3793 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
3794 labels a state as inconsistent just because it has error transitions.
3795 The original form of this check appeared in revision 1.1 of lalr.c,
3796 which was committed on 1991-12-21. Now (at least), changing the
3797 consistency label on such a state appears to have no useful effect in
3798 any of the places it is examined, which I enumerate below. The key
3799 point to understanding each item in this enumeration is that a state
3800 with an error transition is labelled consistent in the first place only
3801 if it has no rules, so the check cannot matter for states that have
3802 rules. (1) Labelling a state as inconsistent will cause set_conflicts
3803 to try to identify its conflicts, and a state must have *rules* to have
3804 conflicts. (2) Labelling a state as inconsistent will affect how
3805 action_row sets the default *rule* for the state. (3) Labelling a
3806 state as inconsistent will cause build_relations to add lookback edges
3807 to *rules* in that state.
3808 * src/state.h (struct state): Word the comment for member consistent
3811 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
3813 Don't depend on C99 features.
3814 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
3815 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
3816 * src/reader.c (check_and_convert_grammar): Fix for-loop.
3817 * src/state.c (state_mark_reachable_states): Fix for-loop.
3818 (state_remove_unreachable_states): Fix for-loop.
3820 Don't widen struct state with member reachable just to temporarily
3821 record reachability. Instead, use a local bitset.
3822 * src/state.h (struct state): Remove member.
3823 * src/state.c (state_new): Don't initialize it.
3824 (state_mark_reachable_states): Rename to...
3825 (state_record_reachable_states): ... this, and use bitset.
3826 (state_remove_unreachable_states): Use bitset.
3828 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
3830 * src/Makefile.am (yacc): Quote target action commands properly so
3831 that the yacc script isn't corrupt. Reported by Hans Aberg at
3832 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
3834 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
3835 the case of pure parsers. Reported by Frans Englich at
3836 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
3837 * THANKS: Add Frans Englich.
3839 * NEWS (2.3a+): In the %code entry, reference section `Bison
3840 Declaration Summary' from the manual now since the %code summary has
3842 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
3843 in the rules section must be terminated by semicolons.
3845 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
3847 Extend the front-end API for %define variables to more completely
3848 mirror the back-end. This will be useful in the future.
3849 * data/bison.m4 (b4_percent_define_get, b4_percent_define_ifdef):
3850 Update comments to mention the new front-end counterparts of these
3852 * src/muscle_tab.c (MUSCLE_COMMON_DECODE): New macro with common code

3860 implementation more closely.
3861 (muscle_percent_define_invalid_value): New function.
3862 * src/muscle_tab.h (muscle_percent_define_get,
3863 muscle_percent_define_ifdef, muscle_percent_define_invalid_value):
3866 2007-05-07 Joel E. Denny <jdenny@ces.clemson.edu>
3868 * NEWS (2.3a+): Mention yesterday's state-removal change.
3869 (2.3a): Remove the %language entry, which was added after 2.3a.

3871 src/conflicts.h, src/lalr.c, src/lalr.h, src/print.c,
3872 src/print_graph.c, src/state.c, src/state.h, tests/conflicts.at,
3873 tests/existing.at: Update copyright date.
3875 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
3877 If conflict resolution makes states unreachable, remove those states,
3878 report rules that are then unused, and don't report conflicts in those

3901 (new_itemsets, save_reductions): Update for rename to nitemset.
3902 * src/closure.c (nritemset): Rename to...

3904 used in the comments.
3905 (closure): Update for rename.
3906 * src/closure.h (nritemset): Update extern to...
3907 (nitemset): ... this.

4026 * tests/input.at (%define errors): Update expected output.
4027 * tests/skeletons.at (%define boolean variables: invalid skeleton

4032 * src/print.c (lookahead_set, state_default_rule): Remove.
4033 (print_reductions): Replace state_default_rule invocation with
4034 equivalent use of yydefact, which was computed in token_actions in
4036 (print_results): Don't allocate lookahead_set.
4038 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
4040 * data/lalr1.java: Prefix all private members with yy.
4042 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
4044 Use YYFPRINTF instead of fprintf where appropriate. Reported by
4045 Sebastien Fricker at

4064 Undo my 2007-02-07 change, switching back to the c-strcase module
4065 introduced in the 2007-02-03 change. Bruno Haible reported that
4066 the 2007-02-07 change would be dangerous in Turkish if we add a
4067 language whose name contains "i", since "i" is not lowercase "I"
4069 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
4070 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
4071 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
4072 * m4/.cvsignore: Remove strcase.m4.
4073 * src/getargs.c: Revert 2007-02-07 change, as follows.
4074 Include c-strcase.h.
4075 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
4077 2007-02-11 Bruno Haible <bruno@clisp.org>
4079 Enable the Java related testsuite tests when the only Java compiler
4080 found is a gcj < 4.3. Discussed at
4081 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
4082 * configure.ac (gt_JAVACOMP): Don't specify a target_version.
4084 2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
4086 * data/Makefile.am: Update copyright date.
4087 * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
4088 yypstate_new returns NULL.
4089 (yypstate_new): Return NULL if malloc does.
4090 * src/reader.c (packgram): Move translation of rule actions from the
4091 beginning of packgram to...
4092 (check_and_convert_grammar): ... here right before packgram is invoked
4093 so it's easier to write more complete comments, and remove redundant
4096 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
4098 As in semantic actions, make @$ in %initial-action, %destructor, and
4099 %printer imply %locations.
4100 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
4102 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
4103 (@$ in %initial-action implies %locations,
4104 @$ in %destructor implies %locations,
4105 @$ in %printer implies %locations): ... these new test cases.
4107 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
4109 Undo most of the 2007-02-03 change, switching to the strcase module
4110 now that gnulib strcase has been fixed.
4111 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
4112 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
4113 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
4114 * m4/.cvsignore: Add strcase.m4.
4115 * src/getargs.c: Revert 2007-02-03 change, as follows.
4116 Don't include c-strcase.h.
4117 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
4118 strcasecmp has "unspecified behavior" outside the POSIX locale,
4119 but it works fine in practice if at least one argument is ASCII,
4120 as is the case in Bison.
4122 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
4124 * tests/java.at: Skip tests if only one of javac/java is present.
4125 Reported by Joel E. Denny.
4126 * tests/atlocal.in: Adjust copyright years.
4128 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
4130 * data/lalr1.java (Stack): Work around old verifiers that disallow
4131 access to the private fields of an inner class, from the outer class.
4132 We can make Stack's fields public because user code doesn't have access
4133 to the instance of Stack used by parse(). Reported by Paul Eggert.
4135 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
4137 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
4138 the right spot for these files?
4139 * bootstrap.conf (gnulib_modules): Add c-strcase.
4140 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
4142 * src/getargs.c: Include c-strcase.h.
4143 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
4144 to avoid unspecified behavior.
4146 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
4148 * doc/bison.texinfo (Decl Summary): Correct typo.
4150 2007-01-30 Paolo Bonzini <bonzini@gnu.org>
4152 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
4153 Complain if the value does not match empty, "true" or "false".
4154 * data/c++.m4: Adjust default definitions of %define variables.
4155 * data/java.m4: Adjust default definitions of %define variables.
4156 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
4158 * tests/input.at (Boolean %define variables): Test new behavior.
4160 2007-01-29 Paolo Bonzini <bonzini@gnu.org>
4162 * NEWS: Mention java.
4163 * TODO: Remove things that are done.
4164 * bootstrap.conf: Add javacomp-script and javaexec-script.
4165 * configure.ac: Invoke gt_JAVACOMP and gt_JAVAEXEC.
4167 * data/Makefile.am: Add new files.
4168 * data/java-skel.m4: New.
4169 * data/java.m4: New.
4170 * data/lalr1.java: New.
4172 * doc/bison.texinfo: Put "A Complete C++ Example" under
4173 C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
4174 under Other Languages.
4176 * src/getargs.c (valid_languages): Add Java.
4177 * src/getargs.h (struct bison_language): Update size of string fields.
4179 * tests/Makefile.am: Add java.at.
4180 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
4181 * tests/java.at: New.
4182 * tests/testsuite.at: Include it.
4184 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
4187 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
4188 at_directive_argv arguments so these no longer have to be global
4189 variables. Also, update the implementation for the following changes.
4190 (fail_for_at_directive_too_many_args,
4191 fail_for_at_directive_too_few_args): Add at_directive_name argument.
4192 (at_directive_name): Remove as at_directive_argv[0] will be used for
4194 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
4195 for the directive name.
4196 (at_directive_argc, at_directive_argv): Make these local within
4197 skel_lex instead of global.
4198 (INITIAL): Update directive start action for above changes.
4199 (SC_AT_DIRECTIVE_ARG): Rename to...
4200 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
4201 (SC_AT_DIRECTIVE_SKIP_WS): Update.
4202 (scan_skel): Move yylex_destroy to...
4203 (skel_scanner_free): ... here.
4204 * tests/skeletons.at (installed skeleton file name): Rename to...
4205 (installed skeleton file names): ... this.
4207 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
4209 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
4210 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
4211 Summary" not "Directives".
4212 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
4213 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
4214 since the former is now the more complete one.
4215 (Prologue Alternatives): Likewise and do the same for %defines.
4216 (Table of Symbols): Add summary of %code, add summary of %define, and
4217 move full %code documentation to...
4218 (Decl Summary): ... here for consistency with other entries in these
4220 Move %define entry in order to keep this list alphabetized.
4221 Reword %define entry a little to put less emphasis on the skeleton
4222 concept, which most users shouldn't have to think about.
4224 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
4226 Adjust to recent gnulib changes.
4227 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
4228 Add string.h, string_.h, unistd_.h, wchar_.h.
4229 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
4230 * src/system.h: Don't include <stpcpy.h>; this is now done by
4233 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
4235 Simplify implementation of unqualified %code, implement macros for
4236 uniform treatment of boolean %define flags. Document %define.
4237 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
4238 b4_percent_code_ifdef): New.
4239 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
4240 * data/c++.m4: Define default value for global_tokens_and_yystype.
4241 * data/glr.cc: Likewise.
4242 * data/location.cc: Use b4_percent_define_flag_if.
4244 * doc/bison.texinfo (Decl Summary): Document %define.
4246 * src/parse-gram.y (Unqualified %code): Change muscle name to
4248 (content.opt): Default to empty.
4250 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
4252 Implement support for relative and absolute skeleton file names.
4253 Discussed starting at
4254 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
4255 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
4256 (Bison Options): Document in --skeleton entry.
4257 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
4258 full_skeleton can't necessarily hold all of pkgdatadir.
4259 If the specified skeleton file name contains a `/', don't prepend
4261 * src/parse-gram.y (prologue_declaration): If the specified skeleton
4262 file name contains a `/', prepend the grammar file directory.
4263 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
4264 * skeletons.at: New file.
4265 (relative skeleton file names): New test case.
4266 (installed skeleton file names): New test case.
4267 * tests/testsuite.at: Include skeletons.at.
4269 * bootstrap: Update copyright to 2007.
4271 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
4273 * bootstrap: Remove occurrences of .#bootmp from the files.
4275 2007-01-17 Akim Demaille <akim@epita.fr>
4277 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
4279 Use per-type %printer.
4281 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
4283 * NEWS, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, data/c.m4,

4291 2007-01-16 Akim Demaille <akim@epita.fr>
4293 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
4295 (Calc++ Scanner): Exit with failure if we can't open the input
4297 Accept "-" standing for stdin.
4298 (Calc++ Top Level): Print the result only if the parsing was
4301 2007-01-16 Akim Demaille <akim@epita.fr>
4303 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
4305 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
4306 and Joel E. Denny <jdenny@ces.clemson.edu>
4308 Clean up %define and %code implementation in M4 some. Most
4309 importantly, rename all related macros to be in the b4_percent_define
4310 and b4_percent_code namespaces. Also, complete support for `.' in
4311 %define variable names and %code qualifiers.
4312 * data/bison.m4 (b4_check_user_names): Check for special
4313 "SKELETON-NAMESPACE(name)" macros instead of using two nested
4315 (b4_get_percent_define, b4_get_percent_code): Rename to...
4316 (b4_percent_define_get, b4_percent_code_get): ... these.
4317 Extend documentation with examples.
4318 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
4319 b4_percent_define_skeleton_variables and
4320 b4_percent_code_skeleton_qualifiers.
4321 Expect any value for the %define variable `foo' to be stored in the
4322 macro named `b4_percent_define(foo)'; expect any %code blocks for the
4323 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
4324 expect any unqualified %code blocks to be stored in a macro named
4325 `b4_percent_code_unqualified'.
4326 Use m4_indir so that %define variable names and %code qualifiers can
4327 contain `.', which is allowed by the grammar parser.
4328 (b4_percent_define_default): New macro to set a default value for a
4330 (m4_wrap): Update wrapped code, and fix some underquoting.
4331 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
4332 Expect grammar uses of %define variables and %code qualifiers to be
4333 defined in b4_percent_define_user_variables and
4334 b4_percent_code_user_qualifiers.
4335 * data/c++.m4: Use b4_percent_define_default rather than
4336 m4_define_default. Fix some underquoting. Skeleton usage of %define
4337 variable define_location_comparison now implies skeleton usage of
4338 %define variable filename_type.
4339 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
4340 data/push.c, data/yacc.c: Update macro names.
4341 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
4344 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
4346 DJGPP specific issues.
4348 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
4349 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
4351 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
4353 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
4354 run parsers in all tests so that Valgrind is invoked during
4355 maintainer-check-valgrind.
4356 (Duplicate representation of merged trees): Free all semantic values.
4357 (Duplicated user destructor for lookahead): Likewise.
4359 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
4361 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
4362 command-line prefix.
4363 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
4364 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
4365 miss Valgrind messages.
4366 (Exploding the Stack Size with Malloc): Likewise.
4368 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
4370 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
4371 locals. Reported by Juan Manuel Guerrero at
4372 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
4373 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
4374 Fix some indentation also.
4375 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
4376 explaining this issue.
4378 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
4379 and Joel E. Denny <jdenny@ces.clemson.edu>
4381 Simplify union and prologue handling, and escape union and lex/parse
4382 params with digraphs.
4383 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
4384 values to the empty string since these are no longer guaranteed
4385 initialized by the front-end.
4386 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
4387 braces around b4_user_stype since this is no longer done by the
4389 * src/files.c, src/files.h (pre_prologue_obstack,
4390 post_prologue_obstack): Remove.
4391 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
4392 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
4393 with digraphs. This fixes lex params and parse params.
4394 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
4395 * src/output.c (prepare): Remove muscle insertion of the prologues.
4396 (output): Remove freeing of pre_prologue_obstack and
4397 post_prologue_obstack.
4398 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
4399 than prologue_augment for prologue parsing so you don't need prologue
4401 (grammar_declaration): For %union RHS, use `braceless' instead of
4402 "{...}" so that braces are already stripped and code is escaped with
4404 * src/reader.c (prologue_augment): Remove.
4405 (reader): Remove initialization of pre_prologue_obstack and
4406 post_prologue_obstack.
4407 * src/reader.h (prologue_augment): Remove.
4409 * data/c.m4: Remove stray parenthesis.
4411 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
4413 Remove quotes from variables names in %define directives and from
4414 qualifiers in %code directives, and restrict the characters that are
4415 allowed in them to M4-friendly ones. For %define, continue to support
4416 the quoted form as a deprecated feature. Discussed starting at
4417 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
4418 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
4420 * doc/bison.texinfo (Prologue Alternatives): Update.
4421 (Decl Summary): In %defines entry, update mention of `%code requires'
4422 and `%code provides'.
4423 (C++ Location Values): Update %define uses.
4424 (Calc++ Parser Interface): Likewise.
4425 (Calc++ Parser): Likewise, and update `%code requires' uses.
4426 (Table of Symbols): Update %code documentation.
4427 * src/parse-gram.y (prologue_declaration): For %define variables, use
4428 `variable' instead of `STRING'.
4429 (grammar_declaration): For %code qualifiers, use `ID' instead of
4431 (variable): New nonterminal that takes an `ID' or a `STRING'.
4432 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
4434 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
4435 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
4436 (%define errors): Update %define uses.
4438 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
4440 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
4441 instead of muscle_insert for %define values so that M4-special
4442 characters are replaced with digraphs.
4443 * tests/input.at (%define errors): Extend to check weird values.
4445 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
4447 Instead of having skeletons declare all valid %define variables and
4448 %code qualifiers, provide macros that retrieve the associated values
4449 and build these lists automatically. Thus Bison will now warn when a
4450 variable or qualifier is not used by the skeleton in the current
4451 invocation regardless of whether it might sometimes be used by that
4452 skeleton in other invocations. Also, move all %define value macros to
4453 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
4454 form, which is replaced by %code.
4455 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
4456 (b4_check_user_names): ... this, and change the series of valid name
4457 arguments to a single list argument for names used in the skeleton
4458 similar to the existing list argument for names used in the grammar.
4459 Warn instead of complaining.
4460 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
4461 values and %code code, to format %code code properly, and to build
4462 lists of all %define variables and %code qualifiers used in the
4463 skeleton: b4_skeleton_percent_define_variables and
4464 b4_skeleton_percent_code_qualifiers.
4465 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
4467 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
4468 the skeleton names lists can finish building first. In place of
4469 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
4470 expect the lists b4_user_percent_define_variables and
4471 b4_user_percent_code_qualifiers.
4472 * data/c++.m4: Where setting default values for b4_parser_class_name,
4473 b4_location_type, b4_filename_type, b4_namespace, and
4474 b4_define_location_comparison, update their names to the
4475 b4_percent_define_ namespace.
4476 * data/glr.c: Don't use b4_check_percent_define_variables and
4477 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
4478 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
4479 (b4_parser_class_name, b4_namespace): Define these using
4480 b4_get_percent_define for parser_class_name and namespace.
4481 * data/location.cc: Use b4_get_percent_define.
4482 * data/push.c: Don't use b4_check_percent_define_variables and
4483 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
4484 * data/yacc.c: Likewise, and don't call m4_exit in
4485 b4_use_push_for_pull_if or m4_wrap code will never execute.
4486 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
4488 (muscle_grow_user_name_list): ... this for consistency with the
4489 terminology used in bison.m4.
4490 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
4491 %define variable names, and rename muscle used_percent_define_variables
4492 to user_percent_define_variables.
4493 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
4494 user_percent_code_qualifiers.
4496 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
4497 {CODE} form is no longer accepted.
4498 * tests/input.at (Reject bad %code qualifiers): Rename to...
4499 (Reject unused %code qualifiers): ... this, and update test output.
4500 (%define error): Update test output.
4502 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
4504 Check for unrecognized %define variables similar to checking for
4505 unrecognized %code qualifiers. Check for redefined %define variables.
4506 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
4508 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
4509 (b4_check_percent_define_variables): New, also wraps it.
4510 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
4511 variables using b4_check_percent_define_variables.
4512 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
4513 all those exercised in the test suite and all those listed in the
4514 `Default values' section of c++.m4. Are there others?
4515 * data/push.c, data/yacc.c: Declare no valid %define variables.
4516 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
4517 similar to muscle_find, but it works even when the muscle stores a
4519 (muscle_grow_used_name_list): New function for constructing the used
4520 name list muscles that b4_check_for_unrecognized_names requires.
4521 * src/parse-gram.y (prologue_declaration): Warn if a variable is
4522 %define'd more than once. Define the b4_used_percent_define_variables
4523 muscle with muscle_grow_used_name_list.
4524 (grammar_declaration): Abbreviate %code code with
4525 muscle_grow_used_name_list.
4526 * tests/input.at (%define errors): New.
4528 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
4530 Provide warn_at, complain_at, and fatal_at function callbacks to the
4531 skeletons, and use this for %code qualifier complaints.
4532 * data/bison.m4 (b4_error_at): New, invoked by...
4533 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
4534 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
4535 @fatal_at(...@) directives.
4536 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
4537 qualifiers in b4_used_percent_code_qualifiers and to use
4539 * src/location.c, src/location.h (boundary_set_from_string): New global
4541 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
4543 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
4544 to b4_used_percent_code_qualifiers.
4545 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
4547 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
4548 (lineno): Rename to...
4549 (out_lineno): ... this so I don't misunderstand it again.
4550 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
4551 here; these newlines are in the input but not the output file.
4552 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
4553 (at_directive_perform): ... this new static function, and add handling
4554 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
4556 * tests/input.at (Reject bad %code qualifiers): Update test output with
4557 locations and extend.
4559 * tests/output.at (Output file name: [, Output file name: ]): Remove
4560 bogus comment about these tests failing.
4562 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
4564 Clean up b4_check_percent_code_qualifiers a little.
4565 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
4566 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
4567 documentation and add examples.
4568 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
4571 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
4573 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
4574 unreliable -- especially when they're hidden inside another macro.
4575 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
4576 data/c.m4: Remove m4_divert(-1).
4577 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
4578 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
4579 m4_divert_push(0) and m4_divert_pop(0).
4580 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
4581 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
4582 pushed and popped by m4sugar, should be first on the stack.
4584 Provide warn, complain, and fatal function callbacks to the skeletons.
4585 This provides more flexibility than m4_fatal, improves the error
4586 message format, and captures messages for translation. Discussed
4588 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
4589 * data/bison.m4 (b4_error): New, invoked by...
4590 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
4591 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
4592 directives. Because these M4 macros might be called when the current
4593 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
4594 the previous removal of uses of m4_divert, which caused trouble.
4595 (b4_check_percent_code_qualifiers): Use b4_complain instead of
4596 m4_fatal to report unrecognized %code qualifiers.
4597 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
4598 push parser requests.
4599 * data/glr.c: Use b4_complain instead of m4_fatal to report
4600 non-deterministic push parser requests.
4601 Update @output usage to @output(...@) form.
4602 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
4603 report missing %defines. Update @output usage to @output(...@) form.
4604 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
4606 * src/main.c (main): Invoke skel_scanner_free.
4607 * src/scan-skel.h (skel_scanner_free): Prototype new function.
4608 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
4609 obstack_for_string from flex-scanner.h.
4610 (YY_DECL): Use to declare skel_lex static.
4611 (decode_at_digraphs): Remove; now handled in the new
4612 SC_AT_DIRECTIVE_ARG start condition.
4613 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
4615 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
4616 at_directive_argv): New static globals.
4617 (INITIAL): Use fail_for_invalid_at.
4618 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
4619 recognize the start of a generalized `@directive(...@)' form and
4621 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
4622 directive args (using the new obstack_for_string), to decode the
4623 contained @ diagraphs, and to perform the directive. It recognizes
4624 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
4626 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
4627 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
4629 (scan_skel): Initialize obstack_for_string on the first call.
4630 (skel_scanner_free): New function to free obstack_for_string.
4631 * tests/input.at (Reject bad %code qualifiers): Update test output.
4633 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
4635 Consolidate the 4 prologue alternative directives (%code, %requires,
4636 %provides, and %code-top) into a single %code directive with an
4637 optional qualifier field. Discussed at
4638 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
4639 * NEWS (2.3a+): Rewrite the existing entry for the prologue
4641 * doc/bison.texinfo (Prologue Alternatives): Update.
4642 (Decl Summary): Update to %code "requires" and %code "provides".
4643 (Calc++ Parser): Update to %code "requires".
4644 (Table of Symbols): Remove entries for %requires, %provides, and
4645 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
4646 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
4647 are replaced by b4_percent_code_provides and b4_percent_code_requires,
4648 which are skeleton-specific.
4649 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
4650 declare what %code qualifiers it supports and to complain if any other
4651 qualifiers were used in the grammar.
4652 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
4653 and b4_user_code([b4_percent_code_provides]) in place of
4654 b4_user_requires and b4_user_provides.
4655 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
4656 Add b4_user_code([b4_percent_code_top]) and
4657 b4_user_code([b4_percent_code]).
4658 Invoke b4_check_percent_code_qualifiers.
4659 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
4660 PERCENT_REQUIRES): Remove.
4661 (grammar_declaration): Remove RHS's for %code-top, %provides, and
4662 %requires. Rewrite the %code RHS as the unqualified form defining the
4663 muscle b4_percent_code. Add another RHS for the qualified %code form,
4664 which defines muscles of the form b4_percent_code_QUALIFIER and the
4665 b4_used_percent_code_qualifiers muscle.
4666 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
4667 PERCENT_REQUIRES): Remove.
4668 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
4669 %code "requires" and %code "provides".
4670 * tests/input.at (Reject bad %code qualifiers): New.
4672 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
4674 Use the new code_props interface for destructors and printers.
4675 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
4676 printer_location members, and change the type of the destructor and
4677 printer members to code_props.
4678 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
4679 symbol_printer_get, semantic_type_destructor_set,
4680 semantic_type_printer_set, default_tagged_destructor_set,
4681 default_tagless_destructor_set, default_tagged_printer_set,
4682 default_tagless_printer_set): Use code_props in arguments and return
4683 types in place of char const * and location.
4684 (symbol_destructor_location_get, symbol_printer_location_get): Remove
4685 since the locations are now contained in the return of
4686 symbol_destructor_get and symbol_printer_get.
4687 * src/output.c (symbol_destructors_output, symbol_printers_output):
4689 (symbol_code_props_output): ... this to eliminate duplicate code.
4690 (output_skeleton): Update to use symbol_code_props_output.
4691 * src/reader.c (symbol_should_be_used): Update use of
4692 symbol_destructor_get.
4693 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
4694 Update uses of the various _destructor_set and _printer_set functions.
4695 * src/symtab.c: (default_tagged_destructor_location,
4696 default_tagless_destructor_location, default_tagged_printer_location,
4697 default_tagless_printer_location): Remove since we...
4698 (default_tagged_destructor, default_tagless_destructor,
4699 default_tagged_printer, default_tagless_printer): ... change the type
4700 of these to code_props.
4701 (symbol_new, semantic_type_new, symbol_destructor_set,
4702 semantic_type_destructor_set, symbol_destructor_get,
4703 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
4704 symbol_check_alias_consistency, default_tagged_destructor_set,
4705 default_tagless_destructor_set, default_tagged_printer_set,
4706 default_tagless_printer_set): Update.
4707 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
4708 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
4710 (symbol_print): Use SYMBOL_CODE_PRINT.
4712 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
4714 Use the new code_props interface for rule actions.
4715 * src/symlist.h (symbol_list): Replace action, action_location, and
4716 used members with a code_props action_props member.
4717 * src/reader.c (symbol_should_be_used, grammar_rule_check,
4718 grammar_midrule_action, grammar_current_rule_merge_set,
4719 grammar_current_rule_symbol_append, packgram): Update.
4720 * src/scan-code.h (translate_rule_action): Remove, no longer used.
4721 * src/scan-code.l (handle_action_dollar): Update.
4722 (translate_rule_action): Remove, no longer used.
4723 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
4725 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
4727 Use the new code_props interface in parse-gram.y.
4728 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
4729 Update all uses of translate_* functions to use the new code_props
4730 interface and to use gram_scanner_last_string_free and
4731 code_scanner_last_string_free where possible.
4732 (grammar_declaration): symbol_list_destructor_set and
4733 symbol_list_printer_set now perform the translation, so don't do it
4734 here. Use gram_scanner_last_string_free where possible.
4735 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
4736 translate_code): Remove, no longer used.
4737 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
4738 symbol_list_printer_set): Perform code translation here rather than
4739 depending on the caller to do so.
4741 * src/symlist.h (struct symbol_list): Correct some documentation typos.
4742 * src/scan-gram.h (gram_last_string): Remove declaration.
4743 * src/scan-gram.l (last_string): Declare it static.
4745 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
4747 Encapsulate code properties and related functionality for the various
4748 destructors, printers, and actions into a code_props structure and
4749 interface. This patch merely implements code_props in scan-code.h and
4750 scan-code.l. Future patches will rewrite other modules to use it.
4751 Discussed starting at
4752 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
4753 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
4754 consistently initialize const structs that have an empty location
4756 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
4757 to ensure consistency.
4758 * src/scan-code.h (code_props): New structure.
4759 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
4760 function, macro, and const global variable for initializing a
4761 code_props with no code.
4762 (code_props_plain_init, code_props_symbol_action_init,
4763 code_props_rule_action_init, code_props_translate_code): The rest of
4764 the new code_props functional interface. Among other things, the init
4765 functions set the code_props kind field so that
4766 code_props_translate_code will know whether to behave like
4767 translate_symbol_action, translate_rule_action, or translate_code.
4768 These old translate functions must remain until all other modules are
4769 updated to use the new code_props interface.
4770 (code_scanner_last_string_free): New function similar to
4771 gram_scanner_last_string_free.
4772 (code_scanner_free): Add documentation.
4773 * src/scan-code.l: Implement the new interface.
4774 (code_lex): Make it static, add a code_props* argument, and remove the
4776 (last_string): New static global similar to the one in scan-gram.l.
4777 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
4779 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
4780 code_props since Bison may one day use this information for destructors
4782 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
4783 (handle_action_dollar): Use symbol_list_n_get and set used flag
4784 directly since symbol_list_n_used_set is removed.
4785 (translate_action): Add a code_props* argument and remove the rule,
4786 action, and location arguments. Pass the code_props* on to code_lex.
4787 (translate_rule_action, translate_symbol_action, translate_code):
4788 Rewrite as wrappers around the new code_props interface.
4789 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
4790 it would eventually need to break the encapsulation of code_props.
4792 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
4794 * etc/.cvsignore: New.
4796 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
4798 Add maintainer-push-check to run maintainer-check using push parsing in
4799 place of pull parsing where available.
4800 * Makefile.am (maintainer-push-check): New.
4801 * data/bison.m4 (b4_use_push_for_pull_if): New.
4802 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
4803 appropriately based on their existing values.
4804 (yypush_parse): Don't print push-parser-specific diagnostics if push
4805 parsing is being used in place of pull parsing.
4806 * data/yacc.c: If push parsing should replace pull parsing, redirect to
4808 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
4809 variable, and insert b4_use_push_for_pull_flag into muscles.
4810 * tests/Makefile.am (maintainer-push-check): New.
4812 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
4814 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
4815 (whether successful or failed) so that yypush_parse can be invoked
4816 again to start a new parse using the same yypstate.
4817 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
4818 check multiple yypull_parse invocations on the same yypstate. For pull
4819 mode, extend to check multiple yyparse invocations.
4820 (Exploding the Stack Size with Alloca): Extend to try with
4822 (Exploding the Stack Size with Malloc): Likewise.
4824 * tests/calc.at (Simple LALR Calculator): Don't specify
4825 %skeleton "push.c" since %push-pull-parser implies that now.
4826 * tests/headers.at (export YYLTYPE): Don't check for the push
4827 declarations. Otherwise, this test case can't be used to see if push
4828 mode can truly emulate pull mode.
4829 * tests/input.at (Torturing the Scanner): Likewise.
4830 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
4831 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
4832 AT_YACC_IF, which now includes the case of push mode since %skeleton
4833 need not be used for push mode. This will be more intuitive once
4834 push.c is renamed to yacc.c.
4836 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
4838 For push mode, convert yyparse from a macro to a function, invoke yylex
4839 instead of passing a yylexp argument to yypull_parse, and don't
4840 generate yypull_parse or yyparse unless %push-pull-parser is declared.
4841 Discussed starting at
4842 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
4843 * data/bison.m4 (b4_pull_if): New.
4844 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
4845 * data/push.c: Improve M4 quoting a little.
4846 (b4_generate_macro_args, b4_parenthesize): Remove.
4847 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
4848 any time a pull parser is requested.
4849 Don't #define this as a wrapper around yypull_parse. Instead, when
4850 both push and pull are requested, make it a function that does that
4852 (yypull_parse): If there's a b4_prefix, #define this to
4853 b4_prefix[pull_parse] when both push and pull are requested.
4854 Don't define this as a function unless both push and pull are
4856 Remove the yylexp argument and hard-code yylex invocation instead.
4857 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
4859 * src/getargs.c (pull_parser): New global initialized to true.
4860 * getargs.h (pull_parser): extern it.
4861 * src/output.c (prepare): Insert pull_flag muscle.
4862 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
4863 (prologue_declaration): Set both push_parser and pull_parser = true for
4864 %push-pull-parser. Set push_parser = true and pull_parser = false for
4866 * src/scan-gram.l: Don't accept %push_parser as an alternative to
4867 %push-parser since there's no backward-compatibility concern here.
4868 Scan %push-pull-parser.
4869 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
4870 instead of %push-parser.
4871 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
4872 prototype it in the module that calls yyparse.
4873 * tests/input.at (Torturing the Scanner): Likewise.
4874 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
4876 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
4878 Update etc/bench.pl. Optimize push mode a little (the yyn change
4879 deserves most of the credit).
4880 * Makefile.am (SUBDIRS): Add etc subdirectory.
4881 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
4882 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
4883 yytoken, yyval, and yyloc declarations to...
4884 (yyparse or yypush_parse): ... here to improve performance. For
4885 yypush_parse invocations after the first, be sure to assign yyn its old
4887 (yypstate_new): Don't bother initializing the yyresult field since the
4888 initial value isn't used.
4889 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
4890 remove the #define that, in push mode, set it to yyps->NAME.
4891 * etc/Makefile.am: New.
4892 * etc/bench.pl: Remove and build it instead from...
4893 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
4894 "tests/bison" from the build directory by default rather than just
4895 invoking "bison" from $PATH.
4896 (calc_grammar): Update push parser code: don't declare yylval globally,
4897 don't define yyparse_wrapper, and don't #define yyparse.
4898 (bench_grammar): Update to check all working combinations of yacc.c,
4899 push.c, impure, pure, pull, and push.
4901 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
4903 For push mode, add pull wrappers around yypush_parse.
4904 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
4905 (yypull_parse): New function wrapping yypush_parse.
4906 (yyparse): New #define wrapping yypull_parse.
4907 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
4909 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
4910 prototype yylex in the module that calls yyparse, and don't prototype
4911 yyparse there. Otherwise, the yyparse expansion won't compile.
4912 * tests/input.at (Torturing the Scanner): Likewise.
4914 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
4916 Enable push parsers to operate in impure mode. Thus, %push-parser no
4917 longer implies %pure-parser. The point of this change is to move
4918 towards being able to test the push parser code by running the entire
4919 test suite as if %push-parser had been declared.
4920 * data/push.c (yypush_parse): For impure mode, remove the
4921 yypushed_char, yypushed_val, and yypushed_loc arguments.
4922 Instead, declare these as local variables initialized to the global
4923 yychar, yylval, and yylloc.
4924 For the first yypush_parse invocation only, restore the initial values
4925 of these global variables when it's time to read a token since they
4926 have been overwritten.
4927 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
4929 * tests/calc.at (Simple LALR(1) Calculator): Always declare
4930 %pure-parser along with %push-parser since this test case was designed
4931 for pure push parsers.
4932 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
4933 (AT_YACC_OR_PUSH_IF): New.
4934 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
4935 add a note that it's still wrong for some cases (as it has been for a
4937 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
4938 %push-parser no longer implies %pure-parser.
4940 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4942 Remove some unnecessary differences between the pull parser code and
4943 the push parser code. This patch enables yynerrs in push mode.
4944 * data/push.c: Reformat M4 a little.
4945 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
4946 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
4947 because push mode is on. Instead, if pure mode is on, move yynerrs
4949 (b4_declare_parser_state_variables): ... here.
4950 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
4951 to yyps->NAME so it can be used in yypush_parse.
4952 (yypush_parse): Don't omit uses of yynerrs in push mode.
4954 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4956 Fix bug such that the first pushed token's value and location are
4957 sometimes overwritten (sometimes by %initial-action) before being used.
4958 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
4959 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
4960 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
4961 more closely mimic the pull parser logic.
4962 Don't copy the pushed token to yychar, yylval, and yylloc until it's
4963 time to read a token, which is after any initialization of yylval and
4965 (gottoken): Rename label to...
4966 (yyread_pushed_token): ... for clarity and to avoid infringing on the
4969 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
4971 Rearrange initialization of the parser state variables so that the
4972 skeleton doesn't have to have a copy for pull mode and another for push
4973 mode. This patch also fixes at least a bug such that yylloc was not
4974 initialized (with b4_location_initial_line and
4975 b4_location_initial_column) upon calling yypush_parse. However, that
4976 initialization now overwrites the first token's location;
4977 %initial-action assigning @$ already did the same thing, and both bugs
4978 will be fixed in a later patch.
4979 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
4980 (b4_declare_parser_state_variables): Remove initialization of yytoken,
4981 yyss, yyvs, yyls, and yystacksize.
4982 (yypstate_new): Remove initialization of some yypstate fields: yystate,
4983 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
4985 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
4986 yyps->NAME so it can be used in yypush_parse.
4987 (yyparse or yypush_parse): For yypush_parse, don't print the
4988 "Starting parse" diagnostic for invocations after the first.
4989 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
4990 yypush_parse, only do it for the first invocation.
4991 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
4992 initialization to occur in yypush_parse but only on the first
4995 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
4997 * data/push.c: Add CPP guards around push parser declarations in both
4998 the header and the code file.
4999 In the code file, move the push parser declarations to the same place
5000 they appear in the header file.
5001 Clean up the M4 some, especially the inconsistent underquoting in
5002 some b4_c_function_def and b4_c_function_decl uses.
5004 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
5006 Encapsulate the push parser state variables into an M4 macro so the
5007 push skeleton doesn't have to list them again for pull mode's yyparse.
5008 For push mode, remove yypush_parse's local equivalents of these
5009 variables to eliminate unnecessary copying between the two sets at
5010 run-time. This patch also fixes at least a bug related to multiple
5011 %initial-action invocations in push mode.
5012 * data/push.c (b4_declare_parser_variables): Rename to...
5013 (b4_declare_scanner_communication_variables): ... this for clarity and
5015 (b4_declare_yyparse_variables): Remove and move its contents to the one
5016 spot where it was invoked.
5017 (b4_declare_parser_state_variables): New macro containing the parser
5018 state variables required by push mode.
5019 (struct yypstate): Replace all fields but yynew with
5020 b4_declare_parser_state_variables.
5021 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
5022 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
5023 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
5024 (yyparse or yypush_parse): For yyparse in pull mode, replace local
5025 parser state variable declarations with
5026 b4_declare_parser_state_variables.
5027 Don't initialize parser state variables when calling yypush_parse since
5028 yypstate_new already does that.
5029 Invoke the user's initial action only upon the first yypush_parse
5031 Remove all code that copies between the local parser state variables
5034 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
5036 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
5037 prevent a name collision in a future patch where these names will
5038 sometimes be #define'd.
5039 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
5040 since it no longer has the same name as the existing argument.
5041 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
5043 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
5044 and Joel E. Denny <jdenny@ces.clemson.edu>
5046 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
5047 that the argument is case-insensitive, and there's no `=' here.
5048 For the %skeleton entry, mention that %language is better.
5049 (Bison Options): Likewise for --language and --skeleton. Move the
5050 --skeleton entry so that the `Tuning the parser' section is sorted
5051 alphabetically on long options.
5052 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
5053 %language directive in detail here; cross-reference the %language
5054 documentation instead.
5055 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
5056 `%require "2.3b"' so that the example is always up-to-date.
5057 (Table of Symbols): Add entries for %language and %skeleton.
5058 * examples/extexi (normalize): Instead of replacing every %require
5059 argument with the current Bison version, just substitute for
5060 `@value{VERSION}'. This guarantees that we're testing what actually
5061 appears in the documentation.
5062 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
5063 rather than `@VERSION@'.
5065 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
5067 * NEWS: Reword the %language news a bit, and put it earlier.
5069 * src/getargs.c (skeleton_arg): Last arg is now location const *.
5070 Rewrite to simplify the logic.
5071 (language_argmatch): Likewise.
5072 (program_name): We now own this var.
5073 * src/getargs.h (struct bison_language): Use char[] rather than
5076 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
5078 * src/complain.c (program_name): Remove decl; no longer needed.
5079 * src/main.c (program_name): Remove; now belongs to getargs.
5081 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
5083 * NEWS: Document %language.
5085 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
5087 * data/c-skel.m4, data/c++-skel.m4: New files.
5088 * data/glr.c: Complain on push parsers.
5090 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
5092 (Decl Summary): Document %language and %skeleton.
5093 (Command line): Document -L.
5095 * examples/extexi: Rewrite %require directive.
5096 * examples/calc++/Makefile.am: Pass VERSION to extexi.
5098 * src/files.c (compute_exts_from_gc): Look in language structure
5100 (compute_file_name_parts): Check whether .tab should be added.
5101 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
5102 (language, skeleton_arg, language_argmatch): New.
5103 (long_options): Add --language.
5104 (getargs): Use skeleton_arg, add -L/--language.
5105 * src/getargs.h: Include location.h.
5106 (struct bison_language, language, skeleton_arg, language_argmatch): New.
5107 * src/output.c (prepare): Pick default skeleton from struct language.
5108 Don't dispatch C skeletons here.
5109 * src/parse-gram.y (PERCENT_LANGUAGE): New.
5110 (prologue_declaration): Add "%language" rule, use skeleton_arg.
5111 * src/scan-gram.l ("%language"): New rule.
5113 * tests/calc.at: Test %skeleton and %language.
5114 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
5115 (AT_GLR_IF): Look for %skeleton "glr.cc".
5116 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
5117 (AT_YACC_IF): Reject %language.
5119 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
5121 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
5122 since it wasn't used; only the typedef name 'semantic_type' is needed.
5123 Also, omit trailing white space.
5125 * bootstrap: Sync from coreutils.
5126 (gnulib_extra_files): Add build-aux/announce.gen.
5127 (slurp): Adjust .gitignore files like .cvsignore files.
5128 * build-aux/announce-gen: Remove from CVS, since bootstrap
5131 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
5133 Make %push-parser imply %pure-parser. This fixes several bugs; see
5134 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
5135 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
5137 * data/push.c: Don't bother testing b4_push_if when deciding whether
5138 to expand b4_declare_parser_variables globally.
5139 (yypush_parse): Likewise in here.
5141 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
5142 (yy_reduce_print): Reformat M4 for readability.
5144 2006-12-15 Bob Rossi <bob@brasko.net>
5145 and Joel Denny <jdenny@ces.clemson.edu>
5147 * data/push.c (yypstate): Add typedef, and update all uses of
5148 struct yypstate to just yypstate.
5149 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
5151 2006-12-14 Bob Rossi <bob@brasko.net>
5153 * data/push.c (yypush_parse): Declare prototype regardless of
5156 2006-12-14 Bob Rossi <bob@brasko.net>
5158 * data/push.c (yyparse): Remove the prototype and the #define when in
5161 2006-12-13 Bob Rossi <bob@brasko.net>
5163 * data/push.c (yypstate_init): Rename to...
5164 (yypstate_new): ... this and use b4_c_function_def.
5165 (yypstate_delete): New.
5166 (yypush_parse): Change parameters yynval and yynlloc to be const.
5167 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
5168 yypstate_delete functions.
5170 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
5172 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
5173 strange test case titles. Reported by Bob Rossi.
5175 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
5177 * TODO: Add pointer to Sylvain Schmitz's work on static detection
5178 of potential ambiguities in GLR grammers.
5180 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
5182 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
5183 `bison ', use m4_index instead of m4_substr since chopping up a string
5184 containing M4-special characters causes problems here.
5186 Fix a couple of bugs related to special characters in user-specified
5187 file names, and make it easier for skeletons to compute output file
5188 names with the same file name prefix as Bison-computed output file
5190 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
5191 b4_parser_file_name and b4_spec_defines_file instead of
5192 @output_parser_name@ and @output_header_name@, which are now redundant.
5193 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
5194 b4_parser_file_name, b4_spec_defines_file, and the new
5195 @basename(FILENAME@) instead of @output_parser_name@ and
5196 @output_header_name@, which inappropriately escaped the file names as
5198 * src/files.c (all_but_ext): Remove static qualifier.
5199 (compute_output_file_names): Move `free (all_but_ext)' to...
5200 (output_file_names_free): ... here since all_but_ext is needed later.
5201 * src/files.h (all_but_ext): Extern.
5202 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
5203 exactly what MUSCLE_INSERT_STRING used to do.
5204 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
5205 characters are escaped properly.
5206 * src/output.c (prepare): Define muscle file_name_all_but_ext as
5208 For pkgdatadir muscle, maintain previous functionality by using
5209 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
5210 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
5211 digraphs would never be expanded. Hopefully no one has M4-special
5212 characters in his Bison installation path.
5213 * src/scan-skel.l: Don't parse @output_header_name@ and
5214 @output_parser_name@ anymore since they're now redundant.
5215 In @output, use decode_at_digraphs.
5216 Parse a new @basename command that invokes last_component.
5217 (decode_at_digraphs): New.
5218 (BASE_QPUTS): Remove unused.
5219 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
5220 (Output file name): New tests.
5222 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
5224 Warn about output files that are generated by the skeletons and that
5225 conflict with other output files.
5226 * data/glr.c: Don't generate the header file here when glr.cc does.
5227 * src/files.c (file_names, file_names_count): New static globals.
5228 (compute_output_file_names): Invoke output_file_name_check for files
5229 not generated by the skeletons and remove existing checks.
5230 (output_file_name_check): New function that warns about conflicting
5232 (output_file_names_free): Free file_names.
5233 * src/files.h (output_file_name_check): Declare.
5234 * src/scan-skel.l: Invoke output_file_name_check for files generated by
5236 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
5237 (Conflicting output files): New tests.
5239 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5241 * doc/bison.texinfo: Fix a couple of typos.
5243 2006-12-08 Bob Rossi <bob@brasko.net>
5245 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
5247 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
5249 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
5250 (yypush_parse): Rename yypvars argument to yyps and remove redundant
5252 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
5253 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
5255 2006-12-07 Bob Rossi <bob@brasko.net>
5256 and Joel Denny <jdenny@ces.clemson.edu>
5258 * data/push.c (yypvarsinit): Change return type from void* to struct
5259 yypvars*. No longer cast to void* on return.
5260 (struct yypvars): Remove yylen since it need not be remembered between
5261 yypushparse invocations.
5262 (yypushparse): Don't copy between yylen and pv->yylen.
5264 2006-12-05 Bob Rossi <bob@brasko.net>
5266 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
5267 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
5268 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
5269 (struct yypvars): Remove b4_declare_parser_variables.
5270 (yypvarsinit): Remove init code for removed variables.
5271 (global scope): Do not declare b4_declare_parser_variables if
5273 (yypushparse): Add b4_declare_parser_variables.
5274 Init new local variables, and remove init code for removed
5277 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
5278 and yyparse for other modes.
5279 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
5280 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
5281 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
5282 (AT_PURE_LEX_IF): True if pure or push parser.
5284 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>

5353 won't take a nonterminal.
5355 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
5357 * tests/testsuite.at (AT_CHECK): Don't miss an exit value of 0 because
5358 it was double-quoted.
5359 * src/Makefile.am (YACC): Use --warnings=all,error so that Bison's own
5360 grammar is maintained with Bison's highest standards.
5361 * src/getargs.c: Fix some typos in Doxygen comments.
5363 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>

5366 later. Reported by Paul Eggert in
5367 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
5368 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
5369 * src/scan-code.l (translate_action): Don't bother invoking
5370 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
5371 (code_scanner_free): Instead of invoking
5372 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,
5374 * src/scan-gram.l (gram_scanner_free): Likewise.
5375 * src/scan-skel.l (scan_skel): Likewise.
5377 2006-11-09 Joel E. Denny <jdenny@ces.clemson.edu>
5379 * src/files.c (tr): Change return type to void.
5380 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
5381 has been called previously for the same key.
5382 (muscle_find): Return storage instead of value so that
5383 --enable-gcc-warnings doesn't produce warnings that the return discards
5384 const. aver that the value and storage are the same since storage
5385 could potentially be NULL when value is not.
5386 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
5389 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
5391 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
5392 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
5393 us a slightly cleaner distribution, and also works.
5394 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
5397 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
5398 and Paul Eggert <eggert@cs.ucla.edu>
5400 Don't let Bison leak memory except when it complains.
5401 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
5402 (spec_defines_file, dir_prefix): Now char *, not const char *,
5403 since they are freed.
5404 * src/files.c: Likewise.
5405 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
5407 (tr): Now operates in-place. All uses changed.
5408 (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
5410 (compute_file_name_parts, compute_output_file_names): Don't store
5411 read-only data in variables that will be freed.
5412 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
5413 src_extension, and header_extension.
5414 (output_file_names_free): New public function to free
5415 spec_verbose_file, spec_graph_file, spec_defines_file,
5416 parser_file_name, and dir_prefix.
5417 * src/getargs.c (getargs): Don't store read-only data in variables that
5419 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
5420 (which previously existed but was unused), and quotearg_free.
5421 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
5422 * src/muscle_tab.c: Likewise.
5423 (muscle_entry): Make the value char const *,
5424 and add a new storage member that is char * and can be freed.
5425 (muscle_entry_free): New private function.
5426 (muscle_init): Use it instead of free.
5427 (muscle_insert, muscle_grow): Update and use new storage member.
5428 (muscle_code_grow): Free the string passed to muscle_grow
5429 since it's not needed anymore.
5430 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
5431 add a new `char *code' member.
5432 ("{...}"): Declare semantic type as code.
5433 * src/scan-code.h (translate_rule_action):
5434 (translate_symbol_action, translate_code, translate_action): Return
5435 `char const *' rather than `char *' since external code should not free
5437 * src/scan-code.l: Likewise.
5438 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
5439 which is "{...}" in the parser.
5440 * tests/Makefile.am (maintainer-check-valgrind): Set
5441 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
5443 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
5445 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
5446 expecting a non-zero exit status sets --leak-check=summary and
5447 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
5448 this case, and we don't want to hear about it.
5450 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
5452 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
5453 instead of from the template, to simplify configuration a bit.
5454 * bootstrap.conf (excluded_files): Don't exclude m4/codeset.m4
5455 and m4/wint_t.m4, as they are needed with the latest gnulib.
5457 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>

5466 the value is a set/used mid-rule value unless
5467 --warnings=midrule-values was specified.
5468 * tests/input.at (Unused values, Unused values before symbol
5469 declarations): Run tests with and without --warnings=midrule-values.
5471 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
5472 than LIST_FREE directly.
5474 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>

5490 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
5492 * src/getargs.c (flags_argmatch): Don't cause segmentation fault for
5493 empty subargument list. For example: `bison --warnings= parser.y'.
5495 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
5497 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
5498 the parser header file so that gcc doesn't warn.
5500 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
5502 Split the default %destructor/%printer into two kinds: <*> and <!>.

5521 * src/symlist.h: Update symbol_list_default*_new prototypes.
5522 (symbol_list.content_type): Split enum value SYMLIST_DEFAULT into
5523 SYMLIST_DEFAULT_TAGGED and SYMLIST_DEFAULT_TAGLESS.

5548 Don't apply the default %destructor/%printer to an unreferenced midrule
5550 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
5551 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
5552 like $@n instead of just @n so that the default %destructor/%printer
5553 logic doesn't see them as user-defined symbols.
5554 (symbol_is_dummy): Check for both forms of the name.
5555 * src/reader.c (packgram): Remove the `$' from each midrule symbol
5556 name for which the midrule value is referenced in any action.
5557 * tests/actions.at (Default %printer and %destructor for mid-rule

5565 * src/reader.c (symbol_should_be_used): Check midrule parent rule for
5567 (packgram): Before invoking grammar_rule_check on any rule, make sure
5568 all actions have already been scanned in order to set `used' flags.
5569 Otherwise, checking that a midrule's $$ is set will not always work
5570 properly because the midrule check must forward-reference the midrule's

5582 to show how these directives may be viewed as code labels.
5584 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
5586 Similar to the recently removed %before-header, add %code-top as the
5587 alternative to the pre-prologue. Mentioned at
5588 <http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00063.html>.

5654 Fix testsuite for ./configure --enable-gcc-warnings:
5655 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.
5656 Otherwise, gcc 4.1.0 (at least) warns about sign comparisons in

5692 * tests/local.at (AT_DATA_GRAMMAR_PROLOGUE):
5693 Include <config.h> unconditionally.
5695 * bootstrap: Sync from coreutils, as follows:
5697 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
5699 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
5700 variable was sometimes used without being initialized. This
5701 messed up the installation of the INSTALL file in some cases.
5703 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
5705 * bootstrap (usage, main program, symlink_to_gnulib): Add option
5706 --copy. Inspired by a suggestion from Bruno Haible.
5708 2006-10-03 Jim Meyering <jim@meyering.net>
5710 * bootstrap: Undo last change to this file, since now gnulib-tool
5711 sticks with the automake default in generating dependencies.
5713 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
5715 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than

5789 Fix test failure reported by Tom Lane in
5790 <http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
5791 and try to make such failures easier to catch in the future.
5792 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
5793 that's now the caller's responsibility.
5794 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
5795 Set yychar = YYEOF if it's negative.
5796 * tests/actions.at (yylex): Abort if asked to read past EOF.
5797 * tests/conflicts.at (yylex): Likewise.
5798 * tests/cxx-type.at (yylex): Likewise.
5799 * tests/glr-regression.at (yylex): Likewise.
5800 * tests/input.at (yylex): Likewise.
5801 * tests/regression.at (yylex): Likewise.
5802 * tests/torture.at (yylex): Likewise.
5804 2006-10-01 Paul Eggert <eggert@cs.ucla.edu>
5806 Fix problems with translating English-language diagnostics.
5807 * bootstrap: Fix bug introduced in recent bootstrap changes, with
5808 respect to bison-runtime pot generation. The YY_ stuff
5809 wasn't being captured.
5810 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
5811 * po/POTFILES.in: Add src/location.c, src/scan-code.l.
5812 * runtime-po/POTFILES.in: Add data/push.c.
5814 2006-09-29 Paul Eggert <eggert@cs.ucla.edu>
5816 Merge bootstrap changes from coreutils.
5818 2006-09-28 Jim Meyering <jim@meyering.net>
5820 Automatically generated dependencies are important even
5821 when all of the sources in a directory come from gnulib.
5822 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
5823 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
5825 2006-09-23 Jim Meyering <jim@meyering.net>
5827 * bootstrap (gnulib_tool_options): Add "--local-dir gl".
5829 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
5831 * bootstrap: Add support for --force.
5832 (usage): New function. Describe usage less tersely.
5833 (CVS_only_file): New var.
5835 2006-09-21 Paul Eggert <eggert@cs.ucla.edu>
5837 * data/push.c (YYPUSH_MORE): Make it an enum instead.
5838 (yypushparse): Use YYPUSH_MORE instead of the mystery constant.
5839 Adjust white space and comments to match GNU style better.
5841 2006-09-20 Bob Rossi <bob@brasko.net>
5843 * data/push.c (yyresult_get): Remove function.
5844 (YYPUSH_MORE): Add #define.
5845 (yypushparse): Modify return value.
5847 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
5849 * stamp-h.in: Remove; no longer needed.
5850 * .cvsignore: Replace autom4te.cache and config.cache with *.cache.
5851 Remove config.h, config.hin, intl (no longer created).
5852 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
5855 Sync bootstrap from coreutils, as follows:
5857 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
5859 * bootstrap (symlink_to_gnulib): New function.
5860 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
5861 to copies-of-gnulib.
5862 (cp_mark_as_generated, slurp, gnulib_files):
5863 Avoid making a copy if it's the same as the old version.
5864 (gnulib_files): Add support for this variable (used by Bison).
5866 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
5868 * src/getargs.c (usage): Rework to use conventions similar to
5869 coreutils, to make translation a bit easier and the code a bit
5870 smaller. Problem reported by Tim Van Holder.
5872 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
5874 Use some of gnulib's new modules, taken from coreutils.
5876 * bootstrap: Sync from coreutils, except add support for gnulib_files.
5877 * bootstrap.conf: New file.
5878 (gnulib_modules): Add configmake, inttypes, unistd.
5879 (XGETTEXT_OPTIONS): Add complain, complain_at,
5880 fatal, fatal_at, warn, warn_at, unexpected_end.
5881 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
5882 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
5884 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
5886 (GNULIB_AUTOCONF_SNIPPET): Remove.
5887 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
5889 * lib/.cvsignore: Add inttypes_.h.
5890 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
5891 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
5892 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
5893 no-longer-necessary initializations.
5894 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
5895 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
5896 use the unistd module.
5897 * src/system.h: Likewise.
5898 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
5899 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
5900 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
5901 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
5902 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
5903 * src/system.h: Include inttypes.h unconditionally, now that we
5904 use the inttypes module. Don't bother to include stdint.h, since
5905 inttypes.h now does that for us.
5906 (LOCALEDIR): Remove, now that we use the configmake module.
5907 * src/getargs.c: Include configmake.h.
5908 * src/main.c: Likewise.
5909 * src/output.c: Likewise.
5910 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
5911 not from $abs_top_builddir, since config.h moved.
5914 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
5915 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
5917 * src/parse-gram.y (symbol_declaration): Don't put statements
5918 before declarations; it's not portable to C89.
5919 * src/scan-code.l (handle_action_at): Likewise.
5921 * src/scan-code.l: Always initialize braces_level; the old code
5922 left it uninitialized and therefore had undefined behavior.
5924 Don't attempt to redefine 'assert', since it runs afoul of
5925 systems where standard headers (mistakenly) include <assert.h>.
5926 Instead, define and use our own alternative, called 'aver'.
5927 * src/reader.c: Don't include assert.h, since we no longer
5929 * src/scan-code.l: Likewise.
5930 * src/system.h (assert): Remove, replacing with....
5931 (aver): New function, taking a bool arg. All uses changed.
5932 * src/tables.c (pack_vector): Ensure that aver arg is bool,
5933 not merely an integer.
5935 2006-09-15 Bob Rossi <bob@brasko.net>
5937 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
5938 * data/c.m4 (YYPUSH): New.
5939 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
5940 * src/getargs.c (push_parser): New var.
5941 * src/getargs.h (push_parser): New declaration.
5942 * src/output.c (prepare): Add macro insertion of `push_flag'.
5943 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
5944 (prologue_declaration): Parse %push-parser.
5945 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
5946 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
5947 list of removed lines from the traces observed.
5948 (AT_CHECK_CALC_LALR): Added push parser tests.
5950 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
5952 * NEWS: Version 2.3a.
5953 * configure.ac (AC_INIT): Likewise.
5955 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
5956 "#define YYSTYPE int" that caused "make maintainer-check" to fail
5957 due to header ordering dependencies. I don't know why the #define
5960 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
5961 runtime cost when YYDEBUG is not defined, and so that some tests
5962 that used to fail now work. Problem and initial suggestion by
5964 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
5965 * data/glr.cc (b4_parser_class_name):
5966 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
5967 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
5968 (yydebug_) [YYDEBUG]: New member.
5969 (yycdebug_): Now defined only if YYDEBUG.
5970 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
5971 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
5972 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
5974 (debug_stream, set_debug_stream, debug_level, set_debug_level):
5975 Define only if YYDEBUG.
5976 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
5978 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
5979 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
5980 AT_CHECK_CALC_GLR_CC that are working now.
5982 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
5984 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
5985 We don't need them in glr.cc, and glr.c defines them.
5986 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
5987 assumes that defining it to anything is the same as defining
5988 it to 1. Problem reported by Paolo Bonzini.
5990 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
5992 * data/c.m4 (b4_null, b4_case): Define.
5993 * src/output.c (prepare_symbols): Use b4_null.
5994 (user_actions_output): Use b4_case.
5996 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
5998 * data/glr.c (b4_shared_declarations): Put start-header first,
5999 before any #includes that we generate, so that feature-test
6000 macros work. Problem reported by Michael Deutschmann in
6001 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
6002 * data/lalr1.cc: Likewise.
6003 * doc/bison.texinfo (Prologue): Document that feature-test macros
6004 should be defined before any Bison declarations.
6005 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
6006 that depend on location.hh after, not before, Bison decls, since
6007 we now include location.hh after the first user prologue.
6009 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
6010 Sander Brandenburg in
6011 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
6012 Also, fix minor white space and comment issues.
6013 (Prologue): Mention that it's better to define feature-test macros
6014 before Bison declarations. Problem reported by Michael Deutschmann.
6016 * README-cvs: Fix typo: "&" should be "&&". Problem reported
6018 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
6019 This adjusts to recent gnulib changes.
6021 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
6023 Finish implementation of per-type %destructor/%printer. Discussed
6025 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
6027 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
6028 * NEWS (2.3+): Add a description of this feature to the default
6029 %destructor/%printer description.
6030 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
6031 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
6032 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
6033 list node contains a semantic type.
6034 * src/symtab.c, src/symtab.h: Extend with a table that associates
6035 semantic types with their %destructor's and %printer's.
6036 (semantic_type_from_uniqstr, semantic_type_get,
6037 semantic_type_destructor_set, semantic_type_printer_set): New functions
6038 composing the public interface of that table.
6039 (symbol_destructor_get, symbol_destructor_location_get,
6040 symbol_printer_get, symbol_printer_location_get): If there's no
6041 per-symbol %destructor/%printer, look up the per-type before trying
6043 * tests/actions.at (Per-type %printer and %destructor): New test case.
6044 * tests/input.at (Default %printer and %destructor redeclared):
6045 Extend to check that multiple occurrences of %symbol-default in a
6046 single %destructor/%printer declaration is an error.
6047 (Per-type %printer and %destructor redeclared, Unused values with
6048 per-type %destructor): New test cases.
6050 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
6052 Require default %destructor/%printer to be declared using
6053 %symbol-default instead of an empty symbol list, and start working on
6054 new per-type %destructor/%printer. Discussed at
6055 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
6056 * NEWS (2.3+): Add %symbol-default to example.
6057 * bison.texinfo (Freeing Discarded Symbols): Likewise.
6058 (Table of Symbols): Add entry for %symbol-default.
6059 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
6060 (generic_symlist, generic_symlist_item): New nonterminals for creating
6061 a list in which each item is a symbol, semantic type, or
6063 (grammar_declaration): Use generic_symlist in %destructor and %printer
6064 declarations instead of symbols.1 or an empty list.
6065 (symbol_declaration, precedence_declaration, symbols.1): Update actions
6066 for changes to symbol_list.
6067 * src/reader.c: Update for changes to symbol_list.
6068 * src/scan-code.l: Likewise.
6069 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
6070 * src/symlist.c, src/symlist.h: Extend such that a list node may
6071 represent a semantic type or a %symbol-default in addition to just an
6072 ordinary symbol. Add switched functions for setting %destructor's and
6074 * tests/actions.at, tests/input.at: Add %symbol-default to all default
6075 %destructor/%printer declarations.
6077 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
6079 Whether the default %destructor/%printer applies to a particular symbol
6080 isn't a question of whether the user *declares* that symbol (in %token,
6081 for example). It's a question of whether the user by any means
6082 *defines* the symbol at all (by simply using a char token, for
6083 example). $end is defined by Bison whereas any other token with token
6084 number 0 is defined by the user. The error token is always defined by
6085 Bison regardless of whether the user declares it with %token, but we
6086 may one day let the user define error as a nonterminal instead.
6087 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
6088 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
6089 the meaning of "user-defined".
6090 * tests/actions.at (Default %printer and %destructor for user-declared
6091 end token): Rename to...
6092 (Default %printer and %destructor for user-defined end token): ...
6095 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
6096 computation of whether to apply the default, don't maintain a list of
6097 every Bison-defined symbol. Instead, just check for a first character
6098 of '$', which a user symbol cannot have, and check for the error token.
6100 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
6102 Don't apply the default %destructor or %printer to the error token,
6103 $undefined, or $accept. This change fits the general rule that the
6104 default %destructor and %printer are only for user-declared symbols,
6105 and it solves several difficulties that are described in the new test
6107 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
6108 * tests/actions.at (Default %printer and %destructor are not for error
6109 or $undefined, Default %printer and %destructor are not for $accept):
6112 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
6114 Allow %start after the first rule.
6115 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
6116 when parsing the first rule.
6117 (check_and_convert_grammar): Search for it here after all grammar
6118 declarations have been parsed. Skip midrules, which have dummy LHS
6120 * src/symtab.c (symbol_is_dummy): New function.
6121 * src/symtab.h (symbol_is_dummy): Declare it.
6122 * tests/input.at (%start after first rule): New test.
6124 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
6126 Redo some of the previous commit: add back the ability to use
6127 non-aliased/undeclared string literals since it might be useful to
6128 those declaring %token-table.
6129 * src/reader.c (check_and_convert_grammar): Undo changes in previous
6130 commit: don't worry about complaints from symbols_pack.
6131 * src/symtab.c (symbol_new, symbol_class_set,
6132 symbol_check_alias_consistency): Undo changes in previous commit: count
6133 each string literal as a new symbol and token, assign it a symbol
6134 number, and don't complain about non-aliased string literals.
6135 (symbols_pack): Since symbol_make_alias still does not decrement symbol
6136 and token counts but does still set aliased tokens to the same number,
6137 symbol_pack_processor now leaves empty slots in the symbols array.
6139 * tests/regression.at (Undeclared string literal): Remove test case
6140 added in previous commit since non-aliased string literals are allowed
6142 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
6143 remove unnecessary string literal declarations.
6144 * tests/sets.at (Firsts): Likewise.
6146 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
6148 Don't allow an undeclared string literal, but allow a string literal to
6149 be used before its declaration.
6150 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
6151 symbols_pack complained.
6152 * src/symtab.c (symbol_new): Don't count a string literal as a new
6154 (symbol_class_set): Don't count a string literal as a new token, and
6155 don't assign it a symbol number since symbol_make_alias does that.
6156 (symbol_make_alias): It's not necessary to decrement the symbol and
6157 token counts anymore. Don't assume that an alias declaration occurs
6158 before any uses of the identifier or string, and thus don't assert that
6159 one of them has the highest symbol number so far.
6160 (symbol_check_alias_consistency): Complain if there's a string literal
6161 that wasn't declared as an alias.
6162 (symbols_pack): Bail if symbol_check_alias_consistency failed since
6163 symbol_pack asserts that every token has been assigned a symbol number
6164 although undeclared string literals have not.
6165 * tests/regression.at (String alias declared after use, Undeclared
6166 string literal): New test cases.
6167 (Characters Escapes, Web2c Actions): Declare string literals as
6169 * tests/sets.at (Firsts): Likewise.
6171 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
6173 In the grammar scanner, STRING_FINISH unclosed constructs and return
6174 them to the parser in order to improve error messages.
6175 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
6176 SC_BRACED_CODE, SC_PROLOGUE): Implement.
6177 * tests/input.at (Unclosed constructs): New test case.
6178 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
6181 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
6184 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
6186 Handle string aliases for character tokens correctly.
6187 * src/symtab.c (symbol_user_token_number_set): If the token has an
6188 alias, check and set its alias's user token number instead of its own,
6189 which is set to indicate the alias. Previously, every occurrence of
6190 the character token in the grammar overwrote that alias indicator with
6192 * tests/input.at (String aliases for character tokens): New test.
6194 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
6196 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
6198 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
6200 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
6201 to prevent failures when building on older platforms.
6202 Check for autopoint failure.
6203 Set XGETTEXT_OPTIONS to values that check for C format strings,
6204 so that translators are warned about them (this also helps
6205 prevent core dumps).
6207 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
6208 function, since it simplifies our code a bit.
6210 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
6211 rather than -W, so we don't get bogus warnings about sign comparisons.
6212 Add -Wpointer-arith, since that warning is useful (it reports code
6213 that does not conform to C89 and that some compilers reject).
6214 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
6215 since it's no longer needed.
6217 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
6219 Clean up scanners a bit.
6220 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
6221 definitions so gcc won't warn when obstack_for_string is unused.
6222 * src/scan-code.l: config.h and system.h are already #include'd by
6223 scan-code-c.c, so get rid of them here.
6224 * src/scan-gram.l: Likewise.
6225 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
6226 definitions rather than duplicating the rest of it.
6227 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
6229 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
6231 Suppress signed/unsigned comparison warnings for yycheck.
6232 * data/c.m4 (b4_safest_int_type): New macro.
6233 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
6234 a signed int type, cast it to b4_safest_int_type first.
6235 * data/yacc.c: Likewise.
6236 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
6239 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
6241 * doc/bison.texinfo: Fix some typos.
6243 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
6245 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
6246 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
6248 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
6249 the latest gnulib does this a different way.
6250 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
6251 translation was patched, so stop omitting it.
6253 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
6255 Enable declaration of default %printer/%destructor. Make the parser
6256 use these for all user-declared grammar symbols for which the user does
6257 not declare a specific %printer/%destructor. Thus, the parser uses it
6258 for token 0 if the user declares it but not if Bison generates it as
6259 $end. Discussed starting at
6260 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
6261 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
6263 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
6264 * NEWS (2.3+): Mention.
6265 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
6266 declare a %destructor for a mid-rule's semantic value. It's just
6267 impossible to declare one specific to it.
6268 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
6269 code. Describe default %destructor form.
6270 * src/parse-gram.y (grammar_declaration): Parse default
6271 %printer/%destructor declarations.
6272 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
6273 and symbol_destructor_location_get rather than accessing the destructor
6274 and destructor_location members of struct symbol.
6275 (symbol_printers_output): Likewise but for %printer's.
6276 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
6278 * src/symtab.c (default_destructor, default_destructor_location,
6279 default_printer, default_printer_location): New static global
6280 variables to record the default %destructor and %printer.
6281 (symbol_destructor_get, symbol_destructor_location_get,
6282 symbol_printer_get, symbol_printer_location_get): New functions to
6283 compute the appropriate %destructor and %printer for a symbol.
6284 (default_destructor_set, default_printer_set): New functions to set the
6285 default %destructor and %printer.
6286 * src/symtab.h: Prototype all those new functions.
6287 * tests/actions.at (Default %printer and %destructor): New test to
6288 check that the right %printer and %destructor are called, that they're
6289 not called for $end, and that $$ and @$ work correctly.
6290 (Default %printer and %destructor for user-declared end token): New
6291 test to check that the default %printer and %destructor are called for
6292 a user-declared end token.
6293 * tests/input.at (Default %printer and %destructor redeclared, Unused
6294 values with default %destructor): New tests to check related grammar
6295 warnings and errors.
6297 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
6299 Clean up handling of %destructor for the end token (token 0).
6300 Discussed starting at
6301 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
6303 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
6305 Make the skeletons consistent in how they pop the end token and invoke
6307 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
6308 state, which has token number 0, since this would invoke the
6309 %destructor for the end token.
6310 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
6311 until after shifting the end token, or else it won't be popped.
6312 * data/yacc.c (yyparse): Likewise.
6314 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
6315 it's the end token. Upon termination, destroy an unshifted lookahead
6316 even when it's the end token.
6317 * data/lalr1.cc (yy::parser::parse): Likewise.
6318 * data/yacc.c (yyparse): Likewise.
6320 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
6321 value warnings for the end token when the user gives the end token a
6324 * tests/actions.at (Printers and Destructors): Test all the above.
6326 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
6328 Update to latest gnulib and gettext versions.
6329 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
6331 (gnulib_files): Add m4/warning.m4. Don't worry about files
6332 overwritten by autopoint.
6333 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
6334 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
6336 Don't use autoreconf; instead, invoke autopoint etc. by hand,
6337 so that we can remove the intl files at a better time.
6338 (intl_files_to_remove): Remove aclocal.m4, since it gets
6339 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
6340 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
6341 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
6342 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
6343 Remove datarootdir hack; no longer needed.
6344 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
6345 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
6346 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
6348 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
6349 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
6351 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
6353 * bootstrap: Adjust to today's change to gnulib-tool by invoking
6354 it with --assume-autoconf='latest-stable'.
6356 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
6358 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
6359 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
6361 * src/muscle_tab.h (muscle_grow): Replace the header comments with
6362 those from muscle_tab.c since the old ones are misleading.
6364 2006-07-13 Akim Demaille <akim@epita.fr>
6366 Support %define "KEY" {VALUE}.
6367 * src/scan-code.h, src/scan-code.l (translate_action)
6368 (translate_rule_action, translate_symbol_action, translate_code):
6369 Return char *, not const char *.
6370 * src/parse-gram.y (declaration): Rename as...
6371 (prologue_declaration): this.
6372 (string_content): Remove this nonterminal, use STRING.
6373 (braceless, content, content.opt): New nonterminal.
6375 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
6377 * src/scan-gram.l (getargs.h): Don't include it.
6379 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
6381 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
6382 rather than a for-loop that declares a local bool variable. This
6383 should work around a compatibility problem with a Cray x1e C++
6384 compiler reported by Hung Nguyen in
6385 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
6386 The for-loop was introduced in the 2004-11-17 change but I don't
6387 know why it was needed.
6389 2006-07-12 Akim Demaille <akim@epita.fr>
6391 * data/c.m4: Comment changes.
6393 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
6395 * src/complain.c (error_message, ERROR_MESSAGE): New.
6397 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
6398 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
6400 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
6402 * NEWS: Instead of %union, you can define and use your own union type
6403 YYSTYPE if your grammar contains at least one <type> tag.
6404 Your YYSTYPE need not be a macro; it can be a typedef.
6405 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
6406 (Union Decl, Decl Summary): Document this.
6407 * data/glr.c (YYSTYPE): Implement this.
6408 * data/glr.cc (YYSTYPE): Likewise.
6409 * data/lalr1.cc (YYSTYPE): Likewise.
6410 * data/yacc.c (YYSTYPE): Likewise.
6411 * src/output.c (prepare): Output tag_seen_flag.
6412 * src/parse-gram.y (declaration, grammar_declaration):
6413 Use 'union_seen' rather than 'typed' to determine whether
6414 %union has been seen, since grammars can now be typed without
6416 (symbol_declaration, type.opt, symbol_def):
6417 Keep track of whether a tag has been seen.
6418 * src/reader.c (union_seen, tag_seen): New vars.
6420 * src/reader.h (union_seen, tag_seen, typed): Likewise.
6421 * src/scan-code.l (untyped_var_seen): New variable.
6422 (handle_action_dollar): Adjust to above changes.
6423 (handle_action_dollar, handle_action_at):
6424 Improve overflow checking for outlandish numbers.
6425 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
6426 avoid new diagnostics generated by above changes.
6427 * tests/regression.at (YYSTYPE typedef): Add test to check
6428 for type tags without %union.
6430 * src/symlist.c (symbol_list_length): Return int, not unsigned
6431 int, since callers expect int. This may need to get revisited
6432 once we have proper integer overflow checking.
6434 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
6435 object is now static.
6437 * src/getargs.c (flags_argmatch): Return void, not int,
6438 to pacify ./configure --enable-gcc-warnings.
6440 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
6441 since last_string is already defined to FLEX_PREFIX (last_string).
6443 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
6445 Implement --warnings/-W.
6446 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
6448 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
6450 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
6451 (warnings_args, warnings_types): New.
6452 (getargs, short_options, long_options): Accept -W/--warnings.
6453 Sort the options by alphabetical order, upper case letter right
6454 before its lower case.
6456 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
6458 Change %merge result type clash warnings to errors. Discussed at
6459 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
6460 * src/reader.c (record_merge_function_type): Use complain_at.
6461 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
6462 declared later): Update test case results.
6464 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
6466 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
6467 to be in alphabetical order.
6468 (trace_args): Spelling fixes.
6470 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
6472 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
6473 so they don't collide with user-defined macros.
6474 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
6475 this was never guaranteed, and now that we're using gnulib stdint,
6476 which defines int_fast16_t to long int, the problem is exposed.
6478 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
6480 * data/c.m4 (b4_basename): Simplify a bit, since we don't
6481 need the full POSIX semantics (and weren't implementing them
6484 Adjust to Autoconf 2.60 and today's gnulib.
6485 * bootstrap (gnulib_modules): Add stdint.
6486 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
6487 no longer copies it.
6488 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
6489 since stdint needs the former and wcwidth (which is now required
6490 by mbswidth) needs the latter.
6491 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
6492 work around a compatibility glitch between gettext 0.14.6 and
6494 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
6495 Do not check for uintptr_t, since new stdint module does the right
6497 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
6498 Add stdint.h, stdint_.h, wcwidth.h.
6499 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
6500 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
6501 stdint.m4, wchar_t.m4, wcwidth.m4.
6502 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
6503 usual order for ../lib/*.h files.
6504 (file_name_split): Use last_component, not base_name, to adjust
6506 * src/parse-gram.h: Include <strverscmp.h> in the usual order
6507 for ../lib/*.h files.
6508 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
6509 Define unconditionally, since we now assume the stdint module.
6510 * src/scan-skel.l: Include <dirname.h>.
6511 (BASE_QPUTS): Use last_component, not base_name.
6512 * src/system.h: Include <unlocked-io.h> in the usual order
6513 for ../lib/*.h files. Include <stdint.h> unconditionally,
6514 since we now use the stdint module.
6515 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
6516 HAVE_UINTPTR_T, since we now use the stdint module.
6517 (base_name): Remove decl, since files now include <dirname.h>
6520 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
6522 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
6524 * data/yacc.c, data/glr.c, data/location.cc: Use them.
6525 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
6527 * tests/calc.at: Adjust.
6529 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
6531 * data/c.m4 (b4_basename): New.
6532 (b4_syncline): Also output the location of its invocation (from
6534 (b4_user_action, b4_define_user_action, b4_user_actions)
6535 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
6536 (b4_user_stype): New.
6537 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
6539 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
6541 In the grammar file, the first column is 1 not 0 on the first line as
6542 on every other line.
6543 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
6544 * tests/input.at (Torturing the Scanner): Update output.
6546 * src/scan-gram.l (scanner_cursor): Declare it static.
6548 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
6550 In warnings, say "previous declaration" rather than "first
6552 * src/symtab.c (redeclaration): Do that here.
6553 * src/reader.c (record_merge_function_type): In the case of a result
6554 type clash, report the previous declaration rather than the very first
6555 one in the grammar file.
6556 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
6557 declared later): Add a third declaration to check this behavior.
6558 * tests/input.at (Incompatible Aliases): Update output.
6560 2006-06-27 Akim Demaille <akim@epita.fr>
6562 * doc/Doxyfile.in: New.
6563 * doc/Makefile.am: Use it.
6564 * src/lalr.h, src/symtab.h: Initial doxygenation.
6566 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
6568 Don't miss %merge result type warnings just because the LHS types are
6569 declared after the %merge. This continues the effort of the previous
6571 * src/reader.c (get_merge_function): Don't set the merger type yet.
6572 (record_merge_function_type): New function for setting the merger type
6573 and checking for clashes.
6574 (grammar_current_rule_merge_set): Set the location of the %merge for
6576 (packgram): Invoke record_merge_function_type for each rule now that
6577 all symbol type declarations have been parsed.
6578 * src/reader.h (merger_list.type_declaration_location): New member
6579 storing the location of the first %merge from which the type for this
6580 merging function was derived.
6581 * src/symlist.h (symbol_list.merger_declaration_location): New member
6582 storing the location of a rule's %merge, if any.
6583 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
6584 declared later): New test to catch the error fixed by the above patch.
6586 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
6588 Get action warnings (grammar_rule_check) right even when symbol
6589 declarations appear after the rules. Discussed at
6590 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
6592 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
6593 Don't mistake the type of $$ in a midrule to be that of its parent
6595 * src/reader.c (grammar_current_rule_end): Don't invoke
6596 grammar_rule_check yet since not all symbol declarations may have been
6598 (grammar_midrule_action): Likewise.
6599 Don't record whether the midrule's $$ has been used yet since actions
6600 haven't been translated yet.
6601 Record the midrule's parent rule and its RHS index within the parent
6603 (grammar_current_rule_action_append): Don't translate the action yet
6604 since not all symbol declarations may have been parsed yet and, thus,
6605 warnings about types for $$, $n, @$, and @n can't be reported yet.
6606 (packgram): Translate the action and invoke grammar_rule_check now that
6607 all symbol declarations have been parsed.
6608 * src/scan-code.l (handle_action_dollar): Now that this is invoked
6609 after parsing the entire grammar file, the symbol list here in the case
6610 of a midrule is actually the midrule's empty RHS, so reference its
6611 parent rule's RHS where necessary.
6612 On the other hand, now that you can already know it's a midrule, you
6613 aren't forced to think $$ has the same type as its parent rule's $$.
6614 (handle_action_at): In the case of a midrule, reference the parent rule
6616 * src/symlist.c (symbol_list_new): Initialize new midrule-related
6618 (symbol_list_length): Now that this is invoked after all rules have
6619 been parsed, a NULL symbol (rather than a NULL symbol list node)
6620 terminates a rule. symbol_list_print already does this correctly.
6621 * src/symlist.h (symbol_list.midrule_parent_rule,
6622 symbol_list.midrule_parent_rhs_index): New members so that midrules can
6623 remember their relationships with their parents.
6624 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
6625 fixed by the above patch.
6626 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
6628 (Unused values): ... this old test case and...
6629 (Unused values before symbol declarations): ... this new test case.
6630 This one is the same as `Unused values' except that all symbol
6631 declarations appear after the rules in order to catch the rest of the
6632 errors fixed by the above patch.
6634 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
6637 * src/reader.c (current_rule): Declare it static since it's no longer
6638 used outside this file.
6639 (grammar_current_rule_action_append): Remove redundant arguments from
6640 translate_rule_action invocation.
6641 * src/reader.h (current_rule): Remove this unused extern.
6642 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
6643 * src/scan-code.l (translate_rule_action): Likewise.
6645 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
6647 Clean up yesterday's patch.
6648 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
6650 * src/reader.c (grammar_current_rule_action_append): ... here for
6651 consistency with grammar_current_rule_symbol_append.
6652 * tests/regression.at (Braced code in declaration in rules section):
6653 Make yyerror and yylex static as usual.
6655 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
6657 Fix bug that mistakes braced code in a declaration in the rules section
6658 to be a rule action. Mentioned at
6659 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
6660 * src/scan-gram.l: Move midrule action detection from the start of the
6661 scanning of any braced code to...
6662 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
6663 action. For readability, use $2 and @2 rather than the equivalent
6665 * tests/regression.at (Braced code in declaration in rules section):
6666 New test to catch the error fixed by the above patch.
6668 Work on code readability some.
6669 * src/scan-code.l (current_rule): Get rid of this misleading and
6670 redundant declaration: it's actually extern'ed in reader.h.
6671 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
6672 translate_action): Add a rule argument and use it instead of the global
6674 (translate_rule_action): This already receives current_rule through an
6675 argument, so pass it on to translate_action instead of assigning
6676 current_rule to current_rule.
6677 (translate_symbol_action, translate_code): Pass rule = NULL to
6680 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
6682 Rename %before-definitions to %start-header and %after-definitions to
6683 %end-header. Don't use these declarations to separate pre-prologue
6684 blocks from post-prologue blocks. Add new order-independent
6685 declarations %before-header and %after-header as alternatives to the
6686 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
6687 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.

6706 (declaration): Update token names and m4 macro names.
6707 When parsing %end-header and %start-header, invoke translate_code

6709 whether these declarations have been seen.
6710 Parse new %after-header and %before-header.
6711 * src/reader.c (before_definitions, after_definitions): Remove.

6727 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
6728 * data/c++.m4 (b4_define_location_comparison): New boolean %define
6729 declaration indicating whether filename_type has an operator==. If
6730 filename_type is `std::string', it defaults to `1', `0' otherwise.
6731 * data/location.cc: Iff b4_define_location_comparison is `1', add
6732 operator== and operator!= for class position and for class location.

6745 Don't put the pre-prologue in the header file. For the yacc.c code
6746 file and the glr.c header and code files, move the pre-prologue before
6747 the token definitions. Add new %before-definitions and
6748 %after-definitions to declare code that will go in both the header file
6749 and code file. Discussed at
6750 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
6751 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
6753 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
6754 * NEWS (2.3+): Describe these changes.
6755 * data/glr.c (b4_pre_prologue): Move from within to before...

6757 Add new b4_before_definitions before b4_token_enums.
6758 Add new b4_after_definitions at the end.
6759 * data/glr.cc (b4_pre_prologue): Replace with...
6760 (b4_before_definitions): ... this in the header file.
6761 (b4_after_definitions): New near the end of the header file.
6762 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
6763 code file right before including the header file.
6764 (b4_before_definitions): New in the previous position of
6765 b4_pre_prologue in the header file.
6766 (b4_after_definitions): New near the end of the header file.
6767 * data/yacc.c: Clean up some m4 quoting especially in the header file.
6768 (b4_token_enums_defines): In the code file, move to right before
6769 YYSTYPE for consistency with the header file.
6770 (b4_before_definitions): New right before b4_token_enums_defines in
6771 both the header and code file.
6772 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
6773 header and code file.
6774 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
6775 of prologues for %union dependencies.
6776 (Decl Summary): In %defines description, mention the effect of
6777 %before-definitions and %after-definitions on the header file.
6778 (Calc++ Parser): Forward declare driver in a %before-definitions rather
6779 than in the pre-prologue so that make check succeeds.
6780 (Table of Symbols): Add entries for %before-definitions and
6782 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
6783 %before-definitions.
6784 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
6785 (declaration): Parse those declarations and append to
6786 b4_before_definitions and b4_after_definitions, respectively.
6787 * src/reader.c (before_definitions, after_definitions): New bools to
6788 track whether those declarations have been seen.
6789 (prologue_augment): Add to the post-prologue if %union,
6790 %before-definitions, or %after-definitions has been seen.
6791 * src/reader.h (before_definitions, after_definitions): New extern's.
6792 * src/scan-gram.l: Scan the new declarations.
6793 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
6794 prologue block in a %before-definitions or a %after-definitions based
6795 on whether the %union is declared.
6796 * tests/regression.at (Early token definitions with --yacc, Early token
6797 definitions without --yacc): Move tests for token definitions into the
6798 post-prologue since token names are no longer defined in the
6801 2006-06-20 Akim Demaille <akim@epita.fr>
6803 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
6804 (symbol_get): Use it.
6805 * src/parse-gram.y: Use it.
6807 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
6809 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
6810 build succeeds when configured with --enable-gcc-warnings.
6812 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
6814 * src/parse-gram.y (char_name): New function.
6815 (CHAR, STRING, string_content): For %printer, properly escape.
6816 (ID): Prefer fputs to fprintf.
6817 (id): Reindent to be consistent with other rules.
6818 Properly quote char.
6820 The Translation Project changed its way of publishing translations
6821 to maintainers. I haven't received any responses to my request
6822 for supporting the old way, or for documenting the new way. I
6823 have modified 'bootstrap' to use screen scraping
6824 (in this case, HTML scraping). This is unreliable and inelegant,
6825 but I don't see any better way. Yuck.
6826 * bootstrap (TP_URL, WGET_COMMAND): New vars.
6827 (get_translations): New function, which uses HTML scraping to
6828 deduce locations of latest translations.
6829 Use this function to grab both bison and bison-runtime .po files.
6830 Don't bother priming the pump for the runtime-po domain any more,
6831 as it's now translated better than bison is.
6833 2006-06-19 Akim Demaille <akim@epita.fr>
6835 * src/scan-gram.l: No longer "parse" things after `%union' until
6836 `{'. Rather, return a single "%union" token.
6837 No longer make symbols: return strings, and leave the conversion
6838 to symbols to the parser.
6839 (SC_PRE_CODE, token_type): Remove.
6840 * src/parse-gram.y (%union): New field `character'.
6843 (ID, ID_COLON): Now that the scanner no longer makes them
6844 identifiers, adjust all uses to invoke symbol_get.
6845 (id_colon): New, wraps the conversion from string to symbol.
6846 (%union): Accept a possible union_name.
6847 (symbol): Now can be a char.
6848 * data/c.m4 (b4_union_name): Leave a default value.
6849 * data/glr.c, data/yacc.c: Use it.
6851 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
6853 For associating token numbers with token names for "yacc.c", don't use
6854 #define statements unless `--yacc' is specified; always use enum
6855 yytokentype. Most important discussions start at:
6856 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
6857 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
6859 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
6860 * NEWS (2.3+): Mention.
6861 * data/c.m4 (b4_yacc_if): New.
6862 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
6864 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
6865 on token name definitions.
6866 * src/getargs.c (usage): Capitalize `Yacc' in English.
6867 * src/output.c (prepare): Define b4_yacc_flag.
6868 * tests/regression.at (Early token definitions): Test that tokens names
6869 are defined before the pre-prologue not just before the post-prologue.
6870 Remove this test case and copy to...
6871 (Early token definitions with --yacc): ... this to test #define's.
6872 (Early token definitions without --yacc): ... and this to test enums.
6874 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
6876 * NEWS: Reword the post-2.3 change to not be so optimistic about
6877 removing the old "look-ahead" spelling.
6878 Update previous look-ahead/lookahead change reports.
6879 * REFERENCES: look-ahead -> lookahead (since that's
6880 what he actually wrote).
6881 * doc/refcard.tex: look ahead -> lookahead,
6882 look-ahead -> lookahead
6884 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
6886 For consistency, use `lookahead' instead of `look-ahead' or
6887 `look_ahead'. Discussed starting at

6964 Bison without installing the yacc script.
6966 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
6968 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
6969 and yytext if they're already #define'd.
6970 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
6971 * src/scan-code-c.c: ... here.

7001 Extract the parsing of user actions from the grammar scanner.
7002 As a consequence, the relation between the grammar scanner and
7003 parser is much simpler. We can also split "composite tokens" back
7005 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
7006 * src/scan-gram.l (add_column_width, adjust_location): Move to and

7068 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
7070 Between Bison releases, manually append `+' to the previous Bison
7071 release number, and use that as a signal to automatically print the
7072 ChangeLog's CVS Id keyword from --version. Discussed starting at
7073 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
7074 * ChangeLog: Add Id header.
7075 * configure.ac (AC_INIT): Append `+' to `2.3'.
7076 * src/.cvsignore: Add revision.c.
7077 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
7078 (BUILT_SOURCES): Add revision.c.
7079 (revision.c): New target rule. This file defines a new global variable
7080 named revision. It initializes it with either the Id from ChangeLog
7081 or, if VERSION doesn't contain `+', with the empty string.
7082 * src/getargs.c (version): Print the value of revision.
7083 * src/revision.h: Extern revision.
7085 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
7087 * NEWS: Version 2.3.
7088 * configure.ac (AC_INIT): Likewise.
7090 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
7092 * data/glr.c (YYRECOVERING): Define to be a function-like macro
7093 with no arguments, not as an object-like macro. This is for
7094 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
7095 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
7096 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
7099 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>

7102 --help output so that we don't have to wait for translation before
7105 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
7107 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".

7117 generated source code. Problem reported by Frans Englich in
7118 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
7120 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
7122 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
7123 shell, not within 'make', so that 'make' by an ordinary builder
7124 (using GNU make) does not worry about configuring gzip. This also
7125 works around a bug reported independently by Keith Thompson and by
7126 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
7127 stderr rather than stdout, messing up the build logs.
7129 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
7131 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
7132 to make sure that YYID will never be unused. This fixes a 'make
7133 maintainer-check' failure caused by the recent changes to the 'Trivial
7134 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
7136 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
7138 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
7140 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
7141 state before an empty RHS is always resolved here. Only the location
7142 of that state is guaranteed to be resolved, and that's enough. This
7143 fixes the remaining bug reported by Derek M. Jones in
7144 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
7145 * tests/glr-regression.at (Uninitialized location when reporting
7146 ambiguity): Test the above case.
7147 Also, the embedded comments in this test case claim it checks the case
7148 of an empty RHS that has inherited the initial location. However, the
7149 corresponding LHS was already resolved, so yyresolveLocations didn't
7150 actually have reason to modify it. Fix this by forcing
7151 nondeterministic operation at the beginning of the parse.
7153 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
7155 * data/c.m4 (b4_yy_symbol_print_generate):
7156 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
7157 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
7158 of the bugs reported today by Derek M Jones in
7159 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
7160 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
7161 defined to be a type name without parens or brackets.
7162 (Location Type): Similarly for YYLTYPE.
7163 * tests/regression.at (Trivial grammars): Put in a test for this
7164 bug that will be caught by 'make maintainer-check' (though not,
7165 alas, by 'make check' unless your compiler is picky).
7167 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>

7174 * data/glr.c (yyreportTree): Make room in yystates for the state
7175 preceding the RHS. This fixes the segmentation fault reported by Derek
7177 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
7178 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
7179 to the user. Reported for yyreportTree by Derek M. Jones later in the
7181 * THANKS: Add Derek M. Jones.
7182 Update my email address.
7183 Fix typo in Steve Murphy's name.
7185 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
7187 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
7188 checking against YYLAST that caused the parser to miss a potential
7189 alternative in its diagnostic.
7190 Problem reported by Maria Jose Moron Fernandez in
7191 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.

7193 * data/yacc.c (yysyntax_error): Likewise.
7194 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
7195 tokens, in case we run into an older C compiler.
7196 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
7197 Use them to check for the off-by-one error fixed above.
7199 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
7200 YYSIZE_T, not size_t.
7201 * tests/regression.at (Trivial grammars): New test, to catch
7202 the error fixed by the above patch.
7204 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7206 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
7208 Reported by Steve Murphy.
7210 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7212 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
7213 * data/glr.cc: b4_location_flag is now b4_locations_flag.
7215 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7217 Implement --trace=m4.
7218 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
7219 * src/output.c (output_skeleton): When set, pass -dV to m4.
7221 Factor the handling of flags in m4.
7222 * src/output.c (prepare): Rename the muscle names debug, defines,
7223 error_verbose to debug_flag, defines_flag, error_verbose_flag.
7224 * data/c.m4: Adjust.
7225 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
7226 Use b4_define_flag_if to define other b4_FLAG_if macros.
7227 (b4_location_if): As a consequence, rename as...
7228 (b4_locations_if): this, for consistency.
7229 Adjust all the skeletons.
7231 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7233 * etc/bench.pm: Shorten bench names.
7235 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
7237 * src/output.h, src/output.c (error_verbose): Move to...

7240 Adjust dependencies.
7242 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
7244 * data/c.m4 (b4_copyright): Put the special exception for Bison
7245 skeletons here, so we don't have to put it in each skeleton. All
7246 uses changed. Suggested by Akim Demaille. Also, wrap the
7247 copyright notice, in case it is longer than 80 columns. Replace
7248 comma by newline after title.
7250 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
7252 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
7253 incompatibility, not a bug. Mention that it wasn't fixed as of
7256 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
7258 * examples/extexi: Enforce the precedence of concatenation over
7260 Reported by Tommy Nordgren.
7262 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
7264 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
7265 with the member "token".
7266 Reported by Martin Nylin.
7268 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
7270 * data/glr.c: Switch to Bison 2.2 special-exception language in
7271 the copyright notice. Use more-regular format for titles and

7281 * data/glr.cc: Remove dead code.
7283 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
7285 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
7286 that variable and the line breaks the bootstrap. Problem reported
7287 by Juan M. Guerrero.

7307 Problem reported by Bob Rossi.
7309 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
7311 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
7312 and didn't really work.
7313 For the index, use @ifnotinfo, not @iftex.
7314 Minor cleanups of spacing and terminology.
7316 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
7318 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Fix the definition
7319 of AT_NAME_PREFIX when %name-prefix is not used.
7321 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
7323 Apply --prefix to C++ skeletons too: they change the namespace.
7324 The test suite already exercize these cases.
7325 * data/c++.m4 (b4_namespace): New.
7326 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
7327 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
7328 * data/yacc.c, data/glr.c: Remove a useless `[]'.
7329 * doc/bison.texinfo: Document it.
7330 (Option Cross Key): Use @multitable in all formats. It looks
7331 nicer, even in TeX outputs.
7332 (Rules): Use the same code whatever the output type is.
7333 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
7334 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
7335 * tests/calc.at: Use it, instead of hard coding `yy'.

7356 Fix two nits reported by twlevo, plus one more that I discovered.
7358 * src/assoc.h (assoc_to_string): Give a name to the arg, as
7359 this is the usual Bison style.
7360 * src/location.h (location_print): Likewise.
7362 * src/reader.h (token_name): Likewise.
7364 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
7366 Fix some nits reported by twlevo.
7367 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
7368 and "POSIX". Use more-modern syntax for URLs. Mention C++
7369 and ask for Java. Don't hardwire OS version numbers. Add
7371 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
7372 * src/conflicts.c (solved_conflicts_obstack): Now static.
7374 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
7376 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
7377 page. Say "you can use it" not "you may use it" as on the web page;
7378 we're describing capabilities not granting permission.
7380 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
7382 * data/glr.c (yyresolveLocations): Rename local variables to avoid
7383 shadowing warnings. Use usual patter for iterating through RHS.
7384 * tests/glr-regression.at
7385 (Uninitialized location when reporting ambiguity):
7386 Modify yylex so that it uses its argument, rather than trying
7387 to rely on ARGSUSED (which doesn't work for gcc with warnings).
7388 const char -> char const.
7390 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
7391 Don't use tabs inside commands; it messes up 'ps'.
7392 Problem reported by twlevo.
7394 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
7396 * tests/glr-regression.at (Uninitialized location when reporting
7397 ambiguity): New test case.
7398 * data/glr.c (yyresolveLocations): New function, which uses
7400 (yyresolveValue): Invoke yyresolveLocations before reporting an
7402 * doc/bison.texinfo (Default Action for Locations): Note
7403 YYLLOC_DEFAULT's usage for ambiguity locations.
7404 (GLR Semantic Actions): Cross-reference those notes.
7406 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
7408 * tests/glr-regression.at (Leaked semantic values when reporting
7409 ambiguity): Remove unnecessary union and type declarations.
7410 (Leaked lookahead after nondeterministic parse syntax error): New test
7412 * data/glr.c (yyparse): Check for zero stacks remaining before
7413 attempting to shift the lookahead so that you don't lose it.
7415 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
7417 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
7418 * tests/glr-regression.at (Leaked semantic values when reporting
7419 ambiguity): New test case.
7420 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
7421 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
7422 now unnecessary yystackp parameter.
7423 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
7424 destructors can be called.
7426 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
7427 in existing testcases.
7429 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
7431 Don't leak semantic values for parent RHS when a user action cuts the
7432 parser, and clean up related code a bit.
7433 * tests/glr-regression.at (Leaked merged semantic value if user action
7434 cuts parse): Rename to...
7435 (Leaked semantic values if user action cuts parse): ... this. Add check
7436 for leaked parent RHS values.
7437 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
7438 between an unresolved state (non-empty chain of semantic options) and
7439 an incomplete one (signaled by an empty chain).
7440 (yyresolveStates): Document the interface. Move all manipulation of a
7441 successfully or unsuccessfully resolved yyGLRState to...
7442 (yyresolveValue): ... here so that yyresolveValue always leaves a
7443 yyGLRState with consistent data and thus is easier to understand.
7444 Remove the yyvalp and yylocp parameters since they are always just
7445 taken from the yys parameter. When reporting a discarded merged value
7446 in debugging output, note that it is incompletely merged. Document the
7448 (yyresolveAction): If resolving any of the RHS states fails, destroy
7449 them all rather than leaking them. Thus, as long as user actions are
7450 written to clean up the RHS correctly, yyresolveAction always cleans up
7451 the RHS of a semantic option. Document the interface.
7453 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>

7456 led to a segmentation fault in GNU Pascal. Problem reported
7459 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
7461 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
7462 mid-rule action inside a nonterminal symbol in order to declare a
7463 destructor for its semantic value.

7518 nodist_PROGRAMS, since we don't need to actually compile the
7519 example if we're just doing a plain 'make'. This avoids bothering
7520 the installer unnecessarily about problems due to weird C++

7529 not portable, according to Posix and the C standard, and it does
7530 not work with Sun C 5.7, where previous #line directives affect

7550 that '#include <string>' works.

7570 During deterministic GLR operation, user actions should be able to
7571 influence the parse by changing yychar. To make this easier to fix and
7572 to make glr.c easier to evolve in general, don't maintain yytoken in
7573 parallel with yychar; just compute yytoken when needed.

7580 yychar rather than *yytokenp to determine the current lookahead.

7600 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
7601 got from <http://bro-ids.org/download.html>. The bug is that
7602 when two actions appeared in succession, the second one was
7603 scanned before the first one was added to the grammar rule
7604 as a midrule action. Bison then output the incorrect warning
7605 "parse.y:905.17-906.36: warning: unused value: $3".

7867 in the yychar entry.
7868 In the yychar entry, remove mention of the local yychar case (pure
7869 parser) since this is irrelevant information when writing semantic
7870 actions and since it's already discussed in `Table of Symbols' where
7871 yychar is otherwise described as an external variable.
7872 In the yychar entry, don't call it the `current' look-ahead since it
7873 isn't when semantic actions are deferred.
7874 In the yychar and yyclearin entries, add note about deferred semantic
7876 Add yylloc and yylval entries discussing look-ahead usage.
7877 (Look-Ahead Tokens): When discussing yychar, don't call it the

7902 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
7903 from which the RHS is taken. Set the lookahead members of the new
7904 yySemanticOption according to the lookahead status for stack yyk.

7906 yyaddDeferredAction.
7907 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead

7918 (Incorrect lookahead during nondeterministic GLR): New test case.
7920 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>

7932 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
7934 * data/glr.c (yyresolveValue): When merging semantic options, if at
7935 least one user action succeeds but a later one cuts the parse, then
7936 destroy the semantic value before returning rather than leaking it.
7937 (yyresolveStates): If a user action cuts the parse and thus
7938 yyresolveValue fails, ignore the (unset) semantic value rather than
7939 corrupting the yyGLRState, and empty the semantic options list since
7940 the user actions should have called all necessary destructors.
7941 Simplify code with YYCHK.
7942 * tests/glr-regression.at (Corrupted semantic options if user action
7943 cuts parse): New test case.
7944 (Undesirable destructors if user action cuts parse): New test case.

8242 sed out the final state number.
8244 Work around portability problem on Solaris 10: flex-generated
8245 files include <stdio.h> before <config.h>, which messes up
8246 because the latter defines __EXTENSIONS__. Address the problem
8247 by creating two new little files that include <config.h> first,

8326 it's no longer just a file.

8328 reads like the already-existing exception for C LALR(1) parsers.

8587 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
8589 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
8591 Undo the parts of the unlocked-I/O change that substituted
8592 putc or puts for printf. This might hurt performance a bit,
8593 but some people prefer the printf style.
8594 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
8595 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.

8622 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
8624 Use unlocked I/O for a minor performance improvement on hosts like
8625 GNU/Linux and Solaris that support unlocked I/O. The basic idea
8626 is to use the gnlib unlocked-io module, and to prefer putc and
8627 puts to printf when either will work (since the latter doesn't
8628 come in an unlocked flavor).
8629 * bootstrap (gnulib_modules): Add unlocked-io.

8648 * src/system.h: Include unlocked-io.h rather than stdio.h.
8650 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as

8700 to allow support for non-posix systems. This is a no-op function
8703 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
8704 handle the lack of pipe/fork functionality on non-posix systems.

8788 local variables whose names begin with 'yy'.
8789 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
8790 Trivial changes from Joel E. Denny.
8792 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
8794 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
8795 don't use alloca any more.
8797 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
8798 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
8799 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.

8810 This works a bit better with glibc, if user code has already included

8829 (yysyntax_error): New function.
8830 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
8831 multiple syntax errors are reported, and alloca is being used.
8832 Instead, reallocate buffers twice as big each time, so that
8833 we waste at most half the allocated memory. Start with a small
8834 (128-byte) buffer that will suffice in most cases anyway.
8835 Use yysyntax_error to do most of the work.
8837 * doc/bison.texinfo (Error Reporting, Table of Symbols):
8838 yynerrs is the number of errors reported, not the number of

8845 Don't start user-code symbols with "yy", to avoid name space problems.
8847 2005-09-19 Akim Demaille <akim@epita.fr>
8849 Remove the traits, failed experiment.
8850 It never proved useful, and anyway because of the current
8851 definition, it was not possible to have several specialization of
8852 this traits, making it useless.
8853 * data/lalr1.cc (yy:traits): Remove.
8854 Inline its definitions in the parser class.
8856 2005-09-19 Akim Demaille <akim@epita.fr>

8879 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
8880 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
8881 is not defined. This is an awful hack, but it's enough for now.
8882 All callers changed.
8883 * tests/glr-regression-at (make_value): Args are const pointers now,
8884 to avoid GCC warning.
8885 (Duplicated user destructor for lookahead): New test. Currently
8886 skipped. It fails on my host but I'm not sure it'll always fail.
8888 2005-09-16 Akim Demaille <akim@epita.fr>
8890 * src/symtab.h (struct symbol): Declare the printer and destructor
8891 as const, to avoid accidental calls to free.

8908 * data/lalr1.cc (yylex_): Remove, inline its code.
8909 (yyreport_syntax_error_): Remove, replaced by...
8910 (yysyntax_error_): this which returns a string and leaves to the
8911 caller the call to the users' error function.
8912 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
8913 Move from members of the parser object...
8914 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):

8938 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
8939 do anything if $@ exists. This reverts part of the 2005-07-07
8942 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
8944 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
8945 contains obsolete information and isn't worth distributing as a
8946 separate file anyway.
8947 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
8948 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.

8955 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
8956 Suggested by twlevo@xs4all.nl.
8958 * data/glr.c (YYCHK1): Do not assume YYE is in range.

8960 Problem reported by twlevo@xs4all.nl.
8962 * doc/bison.texinfo: Don't use "filename", as per GNU coding
8963 standards. Use "file name" or "file" or "name", depending on
8965 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
8966 not to hack/foo.tab.c.
8967 (Calc++ Top Level): 2nd arg of main is not const.
8968 * data/glr.c: b4_filename -> b4_file_name.

8998 (User destructor after an error during a split parse): New test case.
8999 Problem reported by Joel E. Denny in:

9031 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
9033 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
9034 lib-prefix.m4, po.m4.
9036 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
9037 in yydestruct diagnostic, since it might not be an error.
9038 Problem reported by Joel Denny near end of
9039 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
9040 * data/lalr1.cc (yyerturn): Likewise.
9041 * data/yacc.c (yyreturn): Likewise.
9042 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
9044 * src/files.c: Remove obsolete FIXME comment.
9046 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
9047 with the other templates, and to fix bogus run-on messages such
9048 as the one reported at the end of
9049 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
9050 All callers changed to avoid the newline.
9051 (yyprocessOneStack): Output two lines rather than one, to accommodate
9052 the above change. This changes the debug output format slightly.
9054 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
9055 reported by Joel E. Denny in
9056 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
9058 * tests/glr-regression.at (Duplicate representation of merged trees):
9059 New test, from Joel E. Denny in:
9060 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
9061 * THANKS: Add Joel E. Denny.
9063 * configure.ac (AC_INIT): Bump to 2.0c.
9065 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
9067 * NEWS: Version 2.0b.
9069 * Makefile.am (SUBDIRS): Put examples before tests, so that
9070 "make check" doesn't finish with "All 1 tests passed".
9072 * tests/regression.at (Token definitions): Don't rely on
9073 AT_PARSER_CHECK for data that contains backslashes. It currently
9074 uses 'echo', and 'echo' isn't portable if its argument contains
9075 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
9076 that the byte '\0xff' is not printable in the C locale; it is,
9077 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
9078 not printable, so use '\0x81' to test.
9080 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
9081 version of GCC, since the macro is used with non-GCC compilers.
9083 Fix core dump reported by Pablo De Napoli in
9084 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
9085 * tests/regression.at (Invalid inputs with {}): New test.
9086 * src/parse-gram.y (token_name): Translate type before using
9089 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
9090 the user's name space. All uses changed to __attribute__
9092 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
9093 Add __attribute__ ((__noreturn__)).
9095 * etc/clcommit: Remove. We weren't using it, and it failed
9096 "make maintainer-distcheck".
9097 * Makefile.maint: Merge from coreutils.
9098 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
9099 (syntax-check-rules): Change list of rules as described below.
9100 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
9101 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
9102 (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):

9107 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
9108 (makefile-check, po-check, author_mark_check):
9109 (makefile_path_separator_check, copyright-check):
9110 Use grep -n, to make it easier to find violations.
9111 Use CVS_LIST and CVS_LIST_EXCEPT.
9112 (header_regexp, h_re): Remove.
9114 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
9115 (my-distcheck): Use more-modern GCC flags.
9116 (signatures, %.asc): Remove.
9117 (rel-files, announcement): Remove signatures.
9118 Restore old updating code, even though we don't use it, so
9119 that we're the same as coreutils.
9120 (alpha, beta, major): Depend on news-date-check.
9121 Make the upload commands.
9123 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
9124 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
9125 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
9126 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.
9127 * src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise.
9128 * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
9129 * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
9130 * tests/sets.at: Likewise.
9132 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
9133 we comment out the Autoconf version number.
9134 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
9135 it's error-prone and "make maintainer-distcheck" rejects it.
9137 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
9138 Indent calls to "error" to pacify "make maintainer-distcheck",
9139 when the calls are not intended to be translated.
9140 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
9142 * src/Makefile.am (DEFS): Use +=, to pacify
9143 "make maintainer-distcheck".
9144 (bison_SOURCES): Add scan-skel.h.
9145 (sc_tight_scope): New rule, from coreutils.
9147 * src/files.c (src_extension, header_extension):
9148 Now static, not extern.
9149 * src/getargs.c (short_options): Likewise.
9150 * src/muscle_tab.c (muscle_table): Likewise.
9151 * src/parse-gram.y (current_class, current_type, current_prec):
9153 * src/reader.c (grammar_end, previous_rule_end): Likewise.
9154 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
9155 * src/main.c (main): Cast bindtextdomain and textdomain calls to
9156 void, to avoid warning when NLS is disabled.
9157 * src/output.c: Include scan-skel.h.
9158 (scan_skel): Remove decl, since scan-skel.h does this.
9160 Indent calls to "error" to pacify "make maintainer-distcheck".
9161 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
9162 * src/reader.h (gram_end, gram_lineno): New decls to pacify
9163 "make maintainer-distcheck".
9164 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
9165 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
9166 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
9167 (skel_lex_destroy, scan_skel): Move these decls to...
9168 * src/scan-skel.h: New file.
9169 * src/uniqstr.c (uniqstr_assert):
9170 Indent calls to "error" to pacify "make maintainer-distcheck".
9172 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
9175 * tests/torture.at: Revamp to avoid misuse of atoi that
9176 "make maintainer-distcheck" complained about.
9178 * examples/extexi (message): Don't print a message more than once,
9179 and omit line-number decoration that makes Emacs compile think
9180 that informative messages are worth worrying about.
9182 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
9184 * configure.ac: Update version number.
9186 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
9188 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
9189 autogenerated by the maintainer.
9190 * examples/calc++/.cvsignore: Add *.yy.
9192 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
9193 * lib/bitset_stats.c (bitset_stats_init): Likewise.
9194 * lib/bitsetv.c (bitsetv_alloc): Likewise.
9196 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
9198 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
9199 from maintainer-distcheck about casting the argument of 'free'.
9201 * NEWS: Mention recent yytname changes.
9202 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
9204 * bootstrap: For translations that have not yet been upgraded to
9205 the new runtime-po domain, prime the pump by extracting the
9206 relevant strings from the obsolete translations. This code can be
9207 removed once the bison-runtime domain has been translated by each
9210 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
9211 now that token names are already quoted.
9213 Fix problem reported by Anthony Heading.
9214 * data/glr.c (YYTOKEN_TABLE): New macro.
9215 (yytname): Define if YYTOKEN_TABLE.
9216 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
9217 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
9218 (YYERROR_VERBOSE): Define the same way the other skeletons do.
9219 * src/output.c (prepare_symbols): Output token_table_flag.
9221 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
9223 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
9224 again if the first call fails.
9226 * data/glr.c (yytnamerr): New function.
9227 (yyreportSyntaxError): Use it to dequote most string literals.
9228 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
9229 with other skeletons. All uses changed.
9230 (yytnameerr_): New function.
9231 (yyreport_syntax_error): Use it to dequote most string literals.
9232 * data/yacc.c (yytnamerr): New function.
9233 (yyerrlab): Use it to decode most string literals.
9234 * doc/bison.texinfo (Decl Summary, Calling Convention):
9235 Clarify quoting convention of yytname.
9236 * src/output.c (prepare_symbols): Quote all names. This undoes
9237 the 2005-04-17 change, which is now accomplished (mostly) via
9238 changes in the parsers as described above.
9239 * tests/regression.at (Token definitions, Web2c Actions):
9240 Undo most 2005-04-17 change here, too.
9242 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
9244 Fix more problems reported by twlevo@xs4all.nl.
9245 * tests/cxx-type.at: Don't pipe output of ./types through sed to
9246 remove trailing spaces. This loses the exit status of ./types,
9247 and isn't needed since ./types shouldn't be emitting trailing
9249 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
9250 as the stack isn't valid in that case.
9252 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
9253 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
9254 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
9255 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
9257 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
9258 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
9259 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
9262 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
9263 overly-picky compilers that reject 'char *foo = "bar";'.
9265 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
9266 to FILE * parameter, not to stderr. This fixes a typo introduced
9267 in the 2005-07-12 change.
9269 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
9270 warnings from GCC 4.
9272 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
9273 (yyglrShiftDefer, yysplitStack):
9274 Remove unused parameters b4_pure_formals. All uses changed.
9275 (yyglrShift): Remove unused parameters b4_user_formals.
9277 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
9279 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
9281 Destructor cleanups and regularization among the three skeletons.
9282 * NEWS: Document the behavior changes.
9283 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
9284 stack before failing, as the cleanup code will do it for us now.
9285 * data/lalr1.cc (yyerrlab): Likewise.
9286 * data/glr.c (yyparse): Pop everything off the stack before
9287 freeing it, so that destructors get called properly.
9288 * data/lalr1.cc (yyreturn): Likewise.
9289 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
9290 This is more consistent.
9291 * doc/bison.texinfo (Destructor Decl): Mention more reasons
9292 why destructors might be called. 1.875 -> 2.1.
9293 (Destructor Decl, Decl Summary, Table of Symbols):
9294 Some English-language cleanups for %destructor.
9295 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
9296 Add output line for destructor of start symbol.
9297 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
9298 because of that same extra output line.
9300 * NEWS: Document minor wording changes in diagnostics of
9301 Bison-generated parsers.
9302 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
9303 Remove unused formals. All uses changed.
9304 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
9305 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
9306 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
9307 Rename yyoverflowab to yyexhaustedlab.
9308 When memory exhaustion occurs during syntax-error reporting,
9309 report it separately rather than in a single diagnostic; this
9311 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
9312 (Memory Exhausted): Renamed from Parser Stack Overflow.
9313 Revamp wording slightly to prefer "memory exhaustion".
9314 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
9316 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
9318 Add i18n support to the GLR skeleton. Partially fix the C++
9319 skeleton; a C++ expert needs to finish this. Remove debugging
9320 msgids; there's little point to having them translated, since they
9321 can be understood only by someone who can read the
9322 (English-language) source code.
9324 Generate runtime-po/bison-runtime.pot automatically, so that we
9325 don't have to worry about garbage getting in that file. We'll
9326 make sure after the next official release that old msgids don't
9328 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
9330 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
9332 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
9333 Fix typos in explanations of the runtime file.
9334 * bootstrap: Change gettext keyword from YYI18N to YY_.
9335 Use standard Makefile.in.in in runtime-po, since we'll arrange
9336 for backward-compatible bison-runtime.po files in a different way.
9337 * data/glr.c (YY_): New macro, from yacc.c.
9338 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
9339 Translate messages intended for users.
9340 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
9341 the wording in the other skeletons. We don't know that the memory
9343 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
9344 Use same method that yacc.c uses.
9345 Don't translate debugging messages.
9346 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
9347 it doesn't work (yet), and requires C++ expertise to fix.
9348 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
9349 Move defn to a more logical place, to be consistent with other
9351 Don't translate debugging messages.
9352 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
9353 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
9354 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
9355 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
9357 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
9358 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
9360 * tests/glr-regression.at (Badly Collapsed GLR States):
9362 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
9363 yylex should return 0 at EOF rather than aborting.
9365 Improve tests for stack overflow in GLR parser.
9366 Problem reported by twlevo@xs4all.nl.
9367 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
9369 (yyStackOverflow): Just longjmp, but with value 2 so that caller
9370 can handle the problem.
9371 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
9372 (yyparse): New local variable yyresult to record the result.
9373 Use result of setjmp to set it, rather than storing itinto
9375 (yyDone): Remove label.
9376 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
9377 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
9378 if YYABORT is used).
9379 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
9380 yyparse status; put status > 1 into diagnostic.
9381 Check that status==2 works.
9382 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
9383 Use exit status 3 for failure to open (which shouldn't happen).
9385 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
9387 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
9388 1 on syntax error; just let yyparse do its thing.
9389 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
9390 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
9391 (Exploding the Stack Size with Alloca):
9392 (Exploding the Stack Size with Malloc):
9393 Expect exit status 2, not 1, since the parser is supposed to blow
9394 its stack. Problem reported by twlevo@xs4all.nl.
9396 * data/glr.c (yyparse): Don't assume that the initial calls
9397 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
9398 Print a stack-overflow message and fail instead.
9399 Initialize the line-number information before creating the stack,
9400 so that the stack-overflow message can report line zero safely.
9402 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
9404 Fix problems reported by twlevo@xs4all.nl.
9405 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
9406 (yyuserMerge): Provide a default case if b4_mergers is empty.
9407 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
9408 * tests/glr-regression.at
9409 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
9410 Add casts to pacify C++ compilers.
9411 * tests/glr-regression.at (Improper merging of GLR delayed action
9412 sets): Declare yylex before using it.
9413 * tests/Makefile.am (maintainer-check-g++): Fix a stray
9414 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
9415 test for valgrind; valgrind is independent of g++.
9416 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
9417 for compatibility with POSIX 1003.1-2001 (if running coreutils).
9418 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
9419 Use a destructor, so that we can expand the stack. Change
9420 YYSTYPE to char * so that we can free it. Cast result of malloc.
9422 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
9424 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
9425 a valgrind failure. Problem reported by twlevo@xs4all.nl.
9427 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
9429 * PACKAGING: New file, suggested by Bruno Haible and taken from
9430 similar wording in gettext's PACKAGING file.
9431 * NEWS: Mention PACKAGING.
9432 * Makefile.am (EXTRA_DIST): Add PACKAGING.
9434 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
9436 * NEWS: Document recent i18n improvements.
9437 * bootstrap: Get runtime translations into runtime-po.
9438 Create runtime-po files automatically, if possible.
9439 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
9440 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
9441 does not infringe on the user's name space.
9442 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
9443 * doc/bison.texinfo (Internationalization): Revamp the English
9444 and Texinfo syntax a bit, to try to make it clearer.
9445 (Bison Options, Option Cross Key): Mention --print-localedir.
9446 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
9447 YYENABLE_NLS. Quote a bit more.
9448 * runtime-po/.cvsignore: New file.
9449 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
9450 * runtime-po/Rules-quot: Remove; now created by bootstrap.
9451 * runtime-po/quot.sed: Likewise.
9452 * runtime-po/boldquot.sed: Likewise.
9453 * runtime-po/en@quot.header: Likewise.
9454 * runtime-po/en@boldquot.header: Likewise.
9455 * runtime-po/insert-header.sin: Likewise.
9456 * runtime-po/remove-potcdate.sin: Likewise.
9457 * runtime-po/Makevars: Likewise.
9458 * runtime-po/LINGUAS: Likewise.
9459 * runtime-po/de.po: Likewise; we will rely on the translation project
9460 to maintain this, so "bootstrap" should get it.
9461 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
9463 * src/main.c (main): Bind the bison-runtime domain, too.
9465 2005-07-12 Bruno Haible <bruno@clisp.org>
9467 * data/yacc.c: Include <libintl.h> when NLS is enabled.
9468 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
9469 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
9470 * runtime-po: New directory.
9471 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
9472 $(DOMAIN).pot-update rule, so that old messages are never dropped.
9473 * runtime-po/Rules-quot: New file, copied from po/.
9474 * runtime-po/quot.sed: Likewise.
9475 * runtime-po/boldquot.sed: Likewise.
9476 * runtime-po/en@quot.header: Likewise.
9477 * runtime-po/en@boldquot.header: Likewise.
9478 * runtime-po/insert-header.sin: Likewise.
9479 * runtime-po/remove-potcdate.sin: Likewise.
9480 * runtime-po/Makevars: New file.
9481 * runtime-po/POTFILES.in: New file.
9482 * runtime-po/LINGUAS: New file.
9483 * runtime-po/bison-runtime.pot: New file.
9484 * runtime-po/de.po: New file.
9485 * m4/bison.m4: New file.
9486 * Makefile.am (SUBDIRS): Add runtime-po.
9487 (aclocaldir, aclocal_DATA): New variables.
9488 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
9490 * src/getargs.c (usage): Document --print-localedir option.
9491 (PRINT_LOCALEDIR_OPTION): New enum item.
9492 (long_options): Add --print-localedir option.
9493 (getargs): Handle --print-localedir option.
9494 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
9495 (Internationalization): New section.
9497 2005-07-12 Akim Demaille <akim@epita.fr>
9499 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
9500 for consistency with the rest of the code.
9501 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
9504 2005-07-12 Akim Demaille <akim@epita.fr>
9506 * src/parse-gram.y: Use %printer instead of YYPRINT.
9508 2005-07-12 Akim Demaille <akim@epita.fr>
9510 * src/symtab.h, src/symtab.c (symbol_print): New.
9511 * src/symlist.h, src/symlist.c (symbol_list_print): New.
9512 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
9514 2005-07-12 Akim Demaille <akim@epita.fr>
9516 * data/glr.c (b4_syncline): Fix (swap) the definitions of
9517 b4_at_dollar and b4_dollar_dollar.
9519 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
9521 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
9522 and Pennello's paper.
9524 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
9526 * data/yacc.c (yyparse): Undo previous patch. Instead,
9527 set yylsp[0] and yyvsp[0] only if the initial action
9528 sets yylloc and yylval, respectively.
9530 * data/yacc.c (yyparse): In the initial action, set
9531 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
9532 This avoids the use of undefined variables if the initial
9533 action does not set yylloc and/or yylval.
9535 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
9537 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
9538 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
9539 Remove from CVS. These files are automatically generated.
9540 * examples/extexi: Clarify that this file is now part of Bison,
9541 not GNU M4, and that it works with any POSIX-compatible Awk.
9542 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
9543 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
9544 so that we also get calc++-parser.yy. Geneate it.
9545 Use $(AWK), not gawk, since any conforming Awk will do.
9546 Put comment before action, since older 'make' can't handle comment
9548 $(BUILT_SOURCES): List all built sources, not just some of them.
9549 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
9550 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
9551 $($(calc_sources_generated)): Remove unnecessary test for existence
9552 of target. (This had a shell syntax error anyway; a stray "x".)
9553 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
9555 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
9557 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
9558 implied by the other modules.
9560 2005-07-06 Akim Demaille <akim@epita.fr>
9562 Bind examples/calc++ to the package.
9563 * examples/calc++/Makefile: Remove, replaced by...

9565 * examples/calc++/test: Remove input.
9566 * examples/calc++/compile: Remove.
9567 * examples/Makefile.am: New.
9568 * configure.ac, Makefile.am: Adjust.
9569 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
9571 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
9573 * data/glr.c (yyFail): Drastically simplify; since the format argument
9574 never had any % directives, we can simply pass it to yyerror.
9575 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
9576 be modified later, as that is the usual style in glr.c.
9577 Problems reported by Paul Hilfinger.
9579 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
9580 and size overflow errors.
9581 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
9582 in case the user prolog sets feature-test macros like _GNU_SOURCE.
9583 (YYSIZEMAX): New macro.
9584 (yystpcpy): New function, taken from yacc.c.
9585 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
9586 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
9587 so that we don't have to maintain their signatures.
9588 (yyFail): Check for buffer overflow, by using vsnprintf rather
9589 than vsprintf. Allocate a bigger buffer if possible.
9590 Report an error if buffer allocation fails.
9591 (yyStackOverflow): New function.
9592 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
9593 the initialization was successful. It might fail if storage was
9595 (yyexpandGLRStack): Add more checks for storage allocation failure.
9596 Use yyStackOverflow to report failures.
9597 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
9598 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
9599 Don't assume stack number fits in int.
9600 (yysplitStack): Check for storage allocation failure.
9601 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
9602 can print diagnostics on storage allocation failure. All callers
9604 (yyresolveValue): Use yybool for boolean.
9605 (yyreportSyntaxError): Check for size-calculation overflow.
9606 This code is taken from yacc.c.
9607 (yyparse): Check for storage allocation errors when allocating
9610 2005-07-05 Akim Demaille <akim@epita.fr>
9612 Extract calc++ from the documentation.
9613 * doc/bison.texinfo (Calc++): Add the extraction marks.
9614 * examples/extexi: New, from the aborted GNU Programming 2E.
9615 Separate the different paragraph of a file with empty lines.
9616 * examples/Makefile: Use it to extract the whole calc++ example.
9618 2005-06-24 Akim Demaille <akim@epita.fr>
9620 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
9623 2005-06-22 Akim Demaille <akim@epita.fr>
9625 * doc/bison.texinfo (C++ Language Interface): First stab.
9626 (C++ Parsers): Remove.
9628 2005-06-22 Akim Demaille <akim@epita.fr>
9630 * data/lalr1.cc (yylex_): Honor %lex-param.
9632 2005-06-22 Akim Demaille <akim@epita.fr>
9634 Start a set of simple examples.
9635 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
9636 * examples/calc++/calc++-driver.hh,
9637 * examples/calc++/calc++-parser.yy,
9638 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
9639 * examples/calc++/compile, examples/calc++/test: New.
9641 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
9643 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
9644 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
9645 which stems from the 2005-05-27 patch.
9647 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
9649 * data/glr.c: Modify treatment of unused parameters to permit use
9650 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
9652 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
9654 Fix infringement on user name space reported by Janos Zoltan Szabo.
9655 * data/yacc.c (yyparse): strlen -> yystrlen.
9657 2005-05-30 Akim Demaille <akim@epita.fr>
9659 * data/lalr1.cc (_): New.
9660 Translate the various messages.
9662 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
9664 Fix infringement on user name space reported by Bruno Haible.
9665 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
9666 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
9667 the user's name space.
9668 (alloca): Include <stdlib.h> to get it, if it's not built in.
9669 (YYMALLOC, YYFREE): Define only if needed.
9670 (malloc, free): Declare, but only if needed, as this infringes on
9671 the user name space.
9673 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
9675 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
9676 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
9678 * lib/ebitset.c (min, max): Undef before defining.
9679 * lib/vbitset.c (min, max): Likewise.
9680 * lib/subpipe.c (create_subpipe): Save local variables in case
9681 vfork clobbers them.
9683 2005-05-24 Bruno Haible <bruno@clisp.org>
9685 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
9686 error message syntax used by gcc-4.0.
9688 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
9690 * README: Mention m4 1.4.3. Remove obsolete advice about
9691 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
9693 * bootstrap: Remove workaround for problem I encountered with
9694 gettext 0.14.1; it seems to be fixed now.
9696 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
9698 * NEWS: Version 2.0a.
9700 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
9701 the previous change.
9703 Various maintainer cleanups.
9704 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
9705 conftest*, for benefit of CVS commands run at the same time as
9706 "configure". Add build-aux, since "bootstrap" now creates it and
9708 * Makefile.cfg (move_if_change): Remove.
9709 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
9710 (ftp-gnu, www-gnu, move_if_change, local_updates, update):

9712 (config.guess-url_prefix, config.sub-url_prefix):
9713 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):

9715 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
9717 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
9718 this is now the recommended name.
9719 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
9720 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
9721 ylwrap. These files now go into build-aux.
9722 * config/move-if-change: Remove.
9723 * config/prev-version.txt: Bump from 1.75 to 2.0.
9725 * bootstrap: Add stdio-safer, unistd-safer modules.
9726 Remove m4/glibc2.m4 (introduced by latest gnulib, but
9728 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
9729 fopen-safer.c, stdio-safer.h, unistd-safer.h.
9730 * lib/subpipe.c: Include "unistd-safer.h".
9731 (create_subpipe): Make sure all the newly-created
9732 file descriptors are > 2, so that diagnostics don't
9733 get sent down them (which might cause Bison to hang, in theory).
9734 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
9735 * src/files.c (xfopen): Use fopen_safer, not fopen.
9737 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
9738 yesterday's yacc.c fix.
9740 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
9742 * data/glr.c, data/lalr1.cc: Update copyright date.
9744 Fix a destructor bug reported by Wolfgang Spraul in
9745 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
9746 * data/yacc.c (yyabortlab): Don't call destructor, and
9747 don't set yychar to EMPTY.
9748 (yyoverflowlab): Don't call destructor.
9749 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
9750 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
9751 since we no longer output the message "discarding lookahead token
9754 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
9756 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
9757 fix a small glitch in debugging output.
9758 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
9759 after YY_SYMBOL_PRINT where needed.
9761 (struct yyGLRState): Add some comments.
9762 (struct yySemanticOption): Add some comments.
9763 (union yyGLRStackItem): Add comment.
9765 (yymergeOptionSets): Correct this to properly perform the union,
9766 avoiding infinite reported by Michael Rosien.

9810 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
9812 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
9813 Problem reported by Ralf Menzel.
9815 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
9817 * tests/actions.at: Test that stack overflow invokes destructors.
9818 From Marcus Holland-Moritz.
9819 * data/yacc.c (yyerrlab): Move the code that destroys the stack
9821 (yyreturn): to here. That way, destructors are called properly
9822 even if the stack overflows, or the user calls YYACCEPT or
9823 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
9824 (yyoverflowlab): Destroy the lookahead.
9826 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
9828 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
9830 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
9832 * NEWS: Bison-generated C parsers no longer quote literal strings
9833 associated with tokens.
9834 * src/output.c (prepare_symbols): Don't escape strings,
9835 since users don't want to see C escapes.
9836 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
9838 * tests/input.at (Torturing the Scanner): Likewise.
9839 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
9841 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
9843 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
9844 the data size is known to be too small and we can't increase it.
9845 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
9847 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
9849 * src/parse-gram.y: Include quotearg.h.
9850 (string_as_id): Quote $1 before using it as a key, since the
9851 lexer no longer quotes it for us.
9852 (string_content): Don't strip quotes, since lexer no longer
9854 * src/scan-gram.l: Include quotearg.h.
9856 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
9857 a key, since the rest of the lexer doesn't quote it.
9858 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
9859 * tests/regression.at (Token definitions): Check for backslashes
9862 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
9863 (YYSIZE_T): Define to unsigned long int when using an older compiler.
9864 (yyparse): Revamp code to generate long syntax error message, to
9865 make it easier to translate, and to avoid problems with arithmetic
9866 overflow. Change "virtual memory" to "memory" in diagnostic, since
9867 we don't know whether the memory is virtual.
9869 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
9871 * NEWS: Bison-generated C parsers now use the _ macro to
9873 * data/yacc.c (_) [!defined _]: New macro.
9874 All English strings wrapped inside this macro.
9875 * doc/bison.texinfo (Bison Parser): Document _.
9876 * po/POTFILES.in: Include src/parse-gram.c, since it now
9877 includes translateable strings that parse-gram.y doesn't.
9879 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
9881 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
9882 reverting the 2004-10-11 change to this function.
9883 (symbol_check_alias_consistency): Don't call symbol_type_set
9884 if the type name is already correct.
9885 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
9887 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
9889 * tests/regression.at (Token definitions): Don't use a token named
9890 c, as that generates a "#define c ..." that runs afoul of buggy
9891 stdlib.h that uses the identifier c as a member of struct
9892 drand48_data. Problem reported by Horst Wente.
9894 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
9896 * bootstrap: Change translation URL from
9897 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to

9899 redirection glitches. Problem reported by twlevo@xs4all.nl.
9901 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
9903 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
9904 after operands; POSIX says this isn't portable for the c99 command.
9906 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
9908 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
9909 immediately if a data overrun has occurred; this may help us track
9910 down what may be a spurious failure on MacOS.
9912 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
9914 Respond to problems reported by twlevo@xs4all.nl.
9916 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
9918 * src/vcg.h: Comment fix.
9919 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
9920 (G_CMAX): Change to -1 instead of INT_MAX.
9922 * data/yacc.c (yyparse): Omit spaces before #line.
9924 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
9926 * src/tables.c (state_number_to_vector_number): Put it inside an
9927 "#if 0", since it's not currently used. Problem reported by
9930 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
9932 * src/output.c (escaped_output): Renamed from
9933 escaped_file_name_output, since we now use it for symbol tags as
9934 well. All uses changed.
9935 (symbol_destructors_output, symbol_printers_output):
9936 Escape symbol tags too.
9937 Problem reported by Matyas Forstner in
9938 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
9940 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
9942 * src/output.c (user_actions_output, token_definitions_output,
9943 symbol_destructors_output, symbol_printers_output): Likewise.
9944 * src/reader.c (prologue_augment): Likewise.
9945 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
9947 * src/vcg.c (output_edge): Don't quote linestyle arg.
9948 Problem reported by twlevo@xs4all.nl.
9950 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
9952 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
9953 example, reported by Derek M Jones. Also, make the example even
9954 more outrageous, to better illustrate how bad the problem is.
9956 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
9958 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
9959 putsym. Typo reported by Sebastian Piping.
9961 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
9963 * doc/bison.texinfo (Language and Grammar): some -> same
9964 (Epilogue): int he -> in the
9965 Typos reported by Sebastian Piping via Justin Pence.
9967 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
9969 * tests/glr-regression.at (Improper handling of embedded actions
9970 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
9971 embedded actions and $-N in GLR parsers", work around an Autoconf bug
9972 with dollar signs in test names.
9973 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
9974 for a similar reason.
9976 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
9978 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
9979 wants to redefine G_VIEW.
9981 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
9983 * src/vcg.c (get_view_str): Remove case for normal_view.
9984 Problem reported by twlevo@xs4all.nl.
9986 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
9988 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
9989 Problem reported by twlevo@xs4all.nl.
9991 * doc/bison.texinfo: Change @dircategory from "GNU programming
9992 tools" to "Software development". Requested by Richard Stallman
9995 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
9997 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
9998 Problem reported by twlevo@xs4all.nl.
10000 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
10002 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
10003 keyword; it's not needed with modern compilers, and it doesn't
10004 affect correctness with older compilers. Suggested by
10007 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
10009 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
10010 gcc -Wswitch-default.
10011 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
10012 * data/yacc.c (yyparse): Likewise.
10014 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
10016 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
10017 already. Let config.h define any nonstandard values.
10019 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
10021 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
10022 for the benefit of slower hosts. Problem reported by
10023 Nelson H. F. Beebe.
10025 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
10027 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
10028 being defined and not used.
10029 * data/lalr1.cc (yyparse): Likewise.
10030 Use "if (false)" rather than "if (0)".
10032 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
10034 * TODO: Mention that we should allow NUL bytes in tokens.
10036 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
10038 * src/scan-skel.l (<<EOF>>): Don't close standard output.
10039 Problem reported by Hans Aberg.
10041 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
10043 * src/getargs.c (version): Happy new year; update overall
10044 program copyright date from 2004 to 2005.
10046 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
10047 Problem reported by Hans Aberg.
10048 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
10049 (Output file names.): Add a test for the case when standard output
10052 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
10054 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
10055 to fix an oversight in the Bison 2.0 manual.
10057 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
10059 * NEWS: Version 2.0. Reformat the existing news items since
10060 1.875, so that related items are grouped together.
10061 * configure.ac (AC_INIT): Bump version to 2.0.
10062 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
10064 * tests/torture.at (Exploding the Stack Size with Alloca): Set
10065 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
10066 otherwise, we're not testing alloca. Unfortunately there's no
10067 simple way to consult HAVE_ALLOCA here.
10069 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
10072 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
10073 hand. This avoids a warning about comparing int to size_t when
10074 GCC warnings are enabled.
10076 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
10078 * NEWS: Bison-generated parsers no longer default to using the
10079 alloca function (when available) to extend the parser stack, due
10080 to widespread problems in unchecked stack-overflow detection.
10081 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
10082 responsibility to set it to a positive value. This lets the user
10083 specify a value that is not a preprocessor constant.
10084 * data/yacc.c (YYMAXDEPTH): Likewise.
10085 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
10086 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
10087 to be a compile-time constant. However, explain the constraints on it.
10088 Also, explain the constraints on YYINITDEPTH.
10089 (Table of Symbols): Explain that alloca is no longer the default.
10090 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
10093 * doc/bison.texinfo (Location Default Action): Mention that n must
10094 be zero when k is zero. Suggested by Frank Heckenbach.
10096 2004-12-22 Akim Demaille <akim@epita.fr>
10098 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
10099 (parser::state_type, parser::semantic_type, parser::location_type):
10100 Private, not public.
10101 (parser::parse): Return ints, not bool.
10102 Returning a bool introduces a problem: 0 corresponds to false, and
10103 it seems weird to return false on success. Returning true changes
10104 the conventions for yyparse.
10105 Alternatively we could return void and send an exception.
10106 There is no clear consensus (yet?).
10107 (state_stack, semantic_stack, location_stack): Rename as...
10108 (state_stack_type, semantic_stack_type, location_stack_type): these.
10109 Private, not public.
10110 * tests/c++.at: New.
10111 * tests/testsuite.at, tests/Makefile.am: Adjust.
10113 2004-12-21 Akim Demaille <akim@epita.fr>
10115 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
10117 2004-12-21 Akim Demaille <akim@epita.fr>
10119 Don't impose std::string for filenames.
10121 * data/lalr1.cc (b4_filename_type): New.
10122 (position::filename): Use it.
10123 (parser.hh): Move the inclusion of stack.hh and location.hh below
10124 the user code, so that needed headers for the filename type can be
10126 Forward declare them before the user code.
10127 * tests/Makefile.am (check-local, installcheck-local): Pass
10128 TESTSUITEFLAGS to the TESTSUITE.
10130 2004-12-20 Akim Demaille <akim@epita.fr>
10132 Use more STL like names: my_class instead of MyClass.
10134 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
10135 (SemanticStack, SemanticType, StateStack, StateType)
10136 (TokenNumberType, Stack, Slice, Traits, Parser::location)
10137 (Parser::value): Rename as...
10138 (location_stack, location_type, rhs_number_type, semantic_stack)
10139 (semantic_type, state_stack, state_type, token_number_type, stack)
10140 (slice, traits, parser::yylloc, parser::yylval): these.
10142 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
10144 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
10146 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
10147 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
10149 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
10151 Remove uses of 'short int' and 'unsigned short int'. This raises
10152 some arbitrary limits. It uses more memory but nowadays that's
10153 not much of an issue.
10155 This change does not affect the generated parsers; that's a different
10156 task, as some users will want to conserve memory there.
10158 Ideally we should use size_t to represent all object counts, and
10159 something like ptrdiff_t to represent signed differences of object
10160 counts; but that will require more code-cleanup than I have the
10161 time to do right now.
10163 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
10164 Use size_t, not int or short int, to count objects.
10165 * src/closure.c (nritemset, closure): Likewise.
10166 * src/closure.h (nritemset, closure): Likewise.
10167 * src/nullable.c (nullable_compute): Likewise.

10172 * src/tables.c (default_goto, goto_actions): Likewise.
10174 * src/gram.h (rule_number, rule): Use int, not short int.
10175 * src/output.c (prepare_rules): Likewise.
10176 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
10177 errs, reductions): Likewise.

10180 * src/tables.c (vector_number, tally, action_number,
10181 ACTION_NUMBER_MINIMUM): Likewise.
10182 * src/output.c (muscle_insert_short_int_table): Remove.
10184 2004-12-17 Akim Demaille <akim@epita.fr>
10186 * data/lalr1.cc: Extensive Doxygenation.
10187 (error_): Rename as...
10188 (error): this, since it is visible to the user.
10190 (Parser::message): Now an automatic variable from...
10191 (Parser::yyreport_syntax_error_): here.
10192 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
10194 * tests/input.at: Escape $.
10196 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
10198 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
10199 Parenthesize rhs to avoid obscure problems with mistakes like
10200 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
10201 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
10202 b4_rhs_location): Likewise.
10203 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
10204 b4_rhs_location): Likewise.
10206 2004-12-16 Akim Demaille <akim@epita.fr>
10208 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
10209 yacc.c: be sure to stay within yycheck_.
10210 * tests/actions.at: Re-enable C++ tests.
10212 2004-12-16 Akim Demaille <akim@epita.fr>
10214 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
10217 2004-12-16 Akim Demaille <akim@epita.fr>
10219 Use #define to handle the %name-prefix.
10221 * data/glr.c, data/yacc.c: Comment changes.
10222 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
10223 so that one can refer to yylex in the parser file, and have it
10224 renamed, as is the case with other skeletons.
10226 2004-12-16 Akim Demaille <akim@epita.fr>
10228 Move lalr1.cc internals into yy*.

10248 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
10250 Fix some problems reported by twlevo at xs4all.
10251 * src/symtab.c (symbol_new): Report an error if the input grammar
10252 contains too many symbols. This is better than calling abort() later.
10253 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
10254 (struct node, struct graph):
10255 Rename member expand to stretch. All uses changed.
10256 (struct graph): Remove member layoutalgorithm. All uses removed.
10257 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
10258 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.
10260 (N_STRETCH): Rename from N_EXPAND. All uses changed.
10262 2004-12-15 Akim Demaille <akim@epita.fr>
10264 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
10265 Add more Doxygen comments.
10266 (symprint_, stack_print_, reduce_print_, destruct_, pop)
10267 (report_syntax_error_, translate_): Rename as...
10268 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
10269 (yypop_, yyreport_syntax_error_, yytranslate_): this.
10271 2004-12-15 Akim Demaille <akim@epita.fr>
10273 * data/lalr1.cc (lex_): Rename as...
10275 Move the trace here.
10276 Take the %name-prefix into account.
10277 Reported by Alexandre Duret-Lutz.
10279 2004-12-15 Akim Demaille <akim@epita.fr>
10281 Simplify the C++ parser constructor.
10283 * data/lalr1.cc (debug_): Rename as...
10284 (yydebug_): so that the parser's internals are always in the yy*
10287 (b4_parse_param_decl): Remove the leading comma as it is now only
10288 called as unique argument list.
10289 (Parser::Parser): Remove the constructor accepting a location and
10290 an initial debugging level.
10291 Remove from the other ctor the argument for the debugging level.
10292 (debug_level_type, debug_level, set_debug_level): New.
10294 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
10297 2004-12-15 Akim Demaille <akim@epita.fr>
10299 Remove b4_root related material: failure experiment
10300 (which goal was to allow to derive from a class).
10302 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
10303 definitions and uses.
10305 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
10307 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
10308 not 2, since it's not portable to subtract 1 from the start of an
10309 array. The new item 0 is never set or used. All uses changed.
10311 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
10312 the default definition of YYLLOC_DEFAULT. Problem reported
10313 by Frank Heckenbach.
10315 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
10317 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
10318 the normal case and one for the error case. Just use the
10319 first one uniformly. Problem reported by Frank Heckenbach.
10320 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
10321 use exactly the same macro in both places.
10322 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
10323 so that the normal-case YYRHSLOC works for the error case too.
10325 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
10326 (YYLLOC_DEFAULT): Use the same macro as glr.c.
10327 * doc/bison.texinfo (Location Default Action): Don't claim that
10328 we have an array of locations. Use the same macro for both glr
10329 and lalr parsers. Mention YYRHSLOC. Mention what happens when
10332 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
10334 * HACKING: Update email addresses to send announcements to.
10336 * configure.ac (AC_INIT): Bump version to 1.875f.
10338 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
10340 * NEWS: Version 1.875e.
10341 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
10343 * src/scan-skel.l: Include "complain.h", for "fatal".
10345 * src/relation.h (relation_print, relation_digraph):
10346 Relation sizes are of type relation_node, not size_t (this is
10347 merely a doc fix, since the two types are equivalent).
10348 (relation_transpose): Relation sizes are of type relation_node,
10350 * src/relation.c: Likewise.
10351 (top, infinity): Now of type relation_node, not int.
10352 (traverse, relation_transpose): Use relation_node, not int.
10354 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
10355 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
10356 (yyparse): Remove unused local introduced in 2004-10-25 patch.
10358 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
10359 specifying whether the test should be skipped. Use it tp
10360 specify that the [%defines %skeleton "lalr1.cc"] tests currently
10361 fail on some hosts, and should be skipped.
10363 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
10365 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
10366 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
10367 unless otherwise specified below.
10369 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
10370 to allocate kernel_base, kernel_items, kernel_size, since
10371 they needn't be initialized to 0.

10386 (token_actions): Likewise for yydefact, actrow, conflrow,
10388 (save_column): Likewise for froms[symno], tos[symno].
10389 (goto_actions): Likewise for state_count.
10390 (pack_table): Likewise for base, pos, check.
10391 (tables_generate): Likewise for width.
10393 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
10394 for initial core. Just have a separate core, so we needn't worry
10395 about whether kernel_size and kernel_base are initialized.
10397 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
10398 kernel_size, kernel_items): Remove unnecessary initialization.
10399 * src/conflicts.c (conflicts): Likewise.
10400 * src/derives.c (derives): Likewise.

10403 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
10404 conflrow, conflict_table, conflict_list, table, check):
10407 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
10408 This is because all callers pass unsigned int.
10409 * src/closure.h (new_closure): Likewise.
10411 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
10412 (build_relations): Initialize includes[i] in all cases.
10413 * src/reader.c (packgram): Always initialize rules[ruleno].prec
10414 and rules[ruleno].precsym. Initialize members in order.
10415 * src/relation.c (relation_transpose): Always initialize new_R[i]
10417 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
10419 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
10420 conflict_list[0] was always 0, but now it isn't initialized.
10422 * src/table.c (table_grow): When conflict_table grew, the grown
10423 area wasn't cleared. Fix this.
10425 * lib/.cvsignore: Add strdup.c, strdup.h.

10428 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
10430 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
10431 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
10432 GOTO_NUMBER_MAXIMUM, since we occasionally compute
10433 ngotos + 1 without checking for overflow.
10434 (build_relations): Use END_NODE, not -1, to denote end of edges.
10435 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
10436 build_relations): Use goto_number, not int, for goto numbers.
10437 * src/tables.c (save_column, default_goto): Likewise.
10439 2004-11-23 Akim Demaille <akim@epita.fr>
10441 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
10442 of #defining from yystype.
10443 Don't typedef yystype, C++ does not need it.
10444 This lets it possible to forward declare it as union.
10446 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
10448 * bootstrap (gnulib_modules): Add extensions.
10449 Problem reported by Jim Meyering.
10451 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
10453 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
10454 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
10455 src/system.h, src/tables.c: XFREE -> free, to accommodate
10456 recent change to gnulib xalloc.h.
10457 Problem reported by Jim Meyering.
10459 2004-11-17 Akim Demaille <akim@epita.fr>
10461 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
10463 2004-11-17 Akim Demaille <akim@epita.fr>,
10464 Alexandre Duret-Lutz <adl@gnu.org>
10466 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
10468 (YYCDEBUG): Adjust.
10469 Use it instead of cdebug_.
10470 (Parser::debug_stream, Parser::set_debug_stream): New.
10471 (Parser::symprint_): Define cdebug_ for temporary backward
10473 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
10476 2004-11-17 Akim Demaille <akim@epita.fr>
10478 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
10479 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
10480 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
10481 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
10483 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
10485 * data/glr.c (yyloc_default): Remove; not used.
10486 Problem reported by Frank Heckenbach.
10488 2004-10-25 Akim Demaille <akim@epita.fr>
10490 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
10491 Introduce another definition to address simple location arrays.
10492 (yyGLRStack): New member: yyerror_range.
10493 (yyrecoverSyntaxError, yyparse): Update it.
10494 (yyrecoverSyntaxError): Use it when shifting the error token to
10495 have an accurate range, equivalent to the one computed by both
10496 yacc.c and lalr1.cc.
10497 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
10498 that column numbers start at column 0, as per GNU Coding
10499 Standards, the others tests, and the doc.
10500 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
10501 Adjust to the above change (first column is 0).
10502 And adjust the location of the "<error>", now covering the whole
10505 2004-10-22 Akim Demaille <akim@epita.fr>
10506 and Paul Eggert <eggert@cs.ucla.edu>
10508 Remove some arbitrary limits on goto numbers and relations.
10509 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
10510 initial values, since they're never used.
10511 (set_goto_map): ngotos is now unsigned, so test for overflow
10512 by seeing whether it wraps around to zero.
10513 * src/lalr.h (goto_number): Now size_t, not short int.
10514 (GOTO_NUMBER_MAXIMUM): Remove.
10515 * src/relation.c (relation_print, traverse, relation_transpose):
10516 Check for END_NODE rather than looking at sign.
10517 * src/relation.h (END_NODE): New macro.
10518 (relation_node): Now size_t, not short int.
10520 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
10522 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
10523 keyword, not an identifier. Problem reported by Baron Schwartz in
10524 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
10526 2004-10-11 Akim Demaille <akim@epita.fr>
10528 * src/symtab.c (symbol_check_alias_consistency): Also check
10529 type names, destructors, and printers.
10530 Reported by Alexandre Duret-Lutz.
10531 Recode the handling of associativity and precedence in terms
10532 of symbol_precedence_set.
10533 Accept no redeclaration at all, not even equal to the previous
10535 (redeclaration): New.
10536 Use it to factor redeclaration complaints.
10537 (symbol_make_alias): Don't set the type of the alias, let
10538 symbol_check_alias_consistency do it as for other features.
10539 * src/symtab.h (symbol): Add new member prec_location, and
10541 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
10542 * tests/input.at (Incompatible Aliases): New.
10544 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
10546 .cvsignore fixes to accommodate gnulib changes,
10547 and the practice of naming build directories "_build".
10548 * .cvsignore: Add "_*". Sort.
10549 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
10550 * m4/.cvsignore: Add "*_gl.m4".
10552 2004-10-06 Akim Demaille <akim@epita.fr>
10554 * src/parse-gram.y (add_param): Fix the truncation of trailing
10557 2004-10-05 Akim Demaille <akim@epita.fr>
10559 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
10560 whether the reducion was empty or not. This leaves room to
10561 improve the use of YYLLOC_DEFAULT in such a case.
10562 lalr1.cc is still experimental, so changing this is acceptable.
10563 And finally, there are probably not many users who changed the
10564 handling of locations in GLR, so changing is admissible too.
10566 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
10567 empty reduction, set @$ to an empty location ending the previously
10569 Adjust uses to make sure the code is triggered on empty
10571 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
10572 expected output: empty reductions have empty locations.
10574 2004-09-29 Akim Demaille <akim@epita.fr>
10576 * data/lalr1.cc: Move towards a more standard C++ coding style
10577 for templates: Class < T > -> Class<T>.
10579 2004-09-29 Akim Demaille <akim@epita.fr>
10581 * data/lalr1.cc: Reinstall the former ctor, for sake of
10582 compatibility, but warn it will be removed.
10583 Move towards a more standard C++ coding style (i.e., type *var ->
10586 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
10588 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
10589 since it's less likely to work if NULs are involved in the future.
10591 2004-09-27 Akim Demaille <akim@epita.fr>
10593 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
10595 2004-09-27 Akim Demaille <akim@epita.fr>
10597 * data/lalr1.cc (b4_parse_param_decl_1): New.
10598 (b4_parse_param_decl): Use it to have different names between attribute
10599 and argument names.
10600 (b4_cc_constructor_call): Likewise.
10602 2004-09-24 Akim Demaille <akim@epita.fr>
10604 * src/parse-gram.y (add_param): Strip the leading and trailing
10605 blanks from a formal argument declaration.
10606 (YY_LOCATION_PRINT): New.
10608 2004-09-24 Akim Demaille <akim@epita.fr>
10610 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
10611 after the location.
10613 2004-09-24 Akim Demaille <akim@epita.fr>
10615 * doc/bison.texinfo (Table of Symbols): Sort.
10617 2004-09-21 Akim Demaille <akim@epita.fr>
10619 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
10620 the useless parentheses.
10621 Suggested by Paul Eggert.
10623 2004-09-20 Akim Demaille <akim@epita.fr>
10625 Let the initial-action act on the look-ahead, and use it for the
10626 "initial push" (corresponding to an hypothetical beginning-of-file).
10627 And let lalr1.cc honor %initial-action.
10629 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
10631 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
10632 (Parser::Parser): Remove the ctor that used to initialize it.
10633 (Parser::parse): Like in the other skeletons, issue the "starting
10634 parse" message before any action.
10635 Honor %initial-action.
10636 Initialize the stacks with the lookahead.
10637 * data/yacc.c: Let $$ and @$ in %initial-action designate the
10639 Push them in the stacks.
10640 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
10642 2004-09-20 Akim Demaille <akim@epita.fr>
10644 * doc/bison.texinfo (Initial Action Decl): New.
10646 2004-09-20 Akim Demaille <akim@epita.fr>
10648 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
10649 clearer criterion to define it.
10650 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
10651 When reducing on an empty RHS, use the latest stacked location as
10653 yylloc is not always available.
10654 * data/glr.c: Likewise.
10655 Also, honor initial-actions.
10657 2004-09-20 Akim Demaille <akim@epita.fr>
10659 * data/yacc.c (YY_LOCATION_PRINT): New.
10660 Define when we know YYLTYPE's structure, i.e., when the default
10661 YYLLOC_DEFAULT is used.
10662 * data/c.m4 (b4_yysymprint_generate): Use it.
10663 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
10664 value of the result.
10665 (error_start_): Replace with...
10666 (error_range_): this location array.
10667 This allows to replace code relying on the implementation of
10668 locations by portable code.
10669 * data/yacc.c (yylerrsp): Replace with...
10670 (yyerror_range): this.
10671 Every time a token is popped, update yyerror_range[0], to have an
10672 accurate location for the error token.
10673 * data/glr.c (YY_LOCATION_PRINT): New.
10674 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
10675 deference a pointer.
10676 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
10677 report the location in %printers.
10679 * src/scan-skel.l: Instead of abort, report error messages to ease
10680 understanding skeleton scanning failures.
10682 2004-09-16 Akim Demaille <akim@epita.fr>
10684 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
10685 (iterator, const_iterator): these, to be more in the C++ spirit.
10686 Also, return reverse iterators so that when displaying the stack
10687 we display its bottom first.
10688 (Parser::stack_print_, Parser::reduce_print_): Match the messages
10690 We should probably use vector here though.
10692 2004-09-16 Akim Demaille <akim@epita.fr>
10694 Have more complete shift traces.
10696 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
10697 to report Shifts instead of ad hoc YYDPRINTF invocations,
10698 including for the error token.
10699 * data/lalr1.cc (symprint_): Output the location.
10700 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
10701 output the location within the %printer.
10702 Activate GLR tests, at least to make sure they compile properly.
10703 They still don't pass though.
10704 * tests/calc.at: Adjust expect verbose output, since now "Entering
10705 state..." is on a different line than the "Shifting" message.
10707 2004-09-08 Akim Demaille <akim@epita.fr>
10709 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
10710 Bison directive from the Bison file to the invocation of this
10711 macro, so that these directives are passed to
10712 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
10713 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
10714 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
10715 the extra Bison directives instead of the whole series.
10716 Change the grammar so that there are recoverable errors, and
10717 unrecoverable errors. Now we can have the parser give up before
10718 consuming the whole input. As a result we now can observe that
10719 the lookahead is freed when needed.
10720 Change the parser source to parse argv[1] instead of a hard coded
10722 Simplify yylex, and give a value and location to EOF.
10723 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
10724 passed directives already coded in the file.
10725 Add some tests to check the location of "error".
10726 For some tests, the C++ parser is correct, and not yacc.c.
10727 For other tests, they provide different, but unsatisfying, values,
10728 so keep the C++ value so that at least one parser is "correct"
10729 according to the test suite.
10730 (Actions after errors): Remove, this is subsumed by the
10731 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
10733 2004-09-06 Akim Demaille <akim@epita.fr>
10735 * data/lalr1.cc: Adjust the indentation of the labels.
10736 (Parser::pop): New.
10739 2004-09-06 Akim Demaille <akim@epita.fr>
10741 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
10742 argument, an informative message.
10743 Call YY_SYMBOL_PRINT.
10744 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
10745 * data/lalr1.cc (destruct_): Likewise.
10746 In addition, no longer depend on b4_yysymprint_generate and
10747 b4_yydestruct_generate to generate these functions, do it "by
10750 2004-09-03 Akim Demaille <akim@epita.fr>
10752 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
10753 invoked, yydestruct the lookahead.
10754 * tests/calc.at (Calculator $1): Update the expected lengths of
10755 traces: there is an added line for the discarded lookahead.
10756 * doc/bison.texinfo (Destructor Decl): Some rewording.
10757 Define "discarded" symbols.
10759 2004-09-02 Akim Demaille <akim@epita.fr>
10761 * data/lalr1.cc (translate_, destruct_): No reason to be static.
10763 2004-09-02 Akim Demaille <akim@epita.fr>
10765 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
10766 (YYDSYMPRINTF): Rename as...
10767 (YY_SYMBOL_PRINT): this.
10768 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
10770 Use it instead of direct symprint_ calls.
10771 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
10774 2004-09-02 Akim Demaille <akim@epita.fr>
10776 * data/lalr1.cc (b4_yysymprint_generate): New.
10777 (symprint_): New member function, defined when YYDEBUG.
10778 Use it consistently instead of token/nterm debugging output by
10780 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
10781 %printer calls to use cdebug_ when using lalr1.cc.
10783 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
10785 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
10786 with #ifdef YYDEBUG.
10788 2004-08-26 Akim Demaille <akim@epita.fr>
10790 * doc/bison.texinfo (Implementing Loops): Rename as...
10791 (Implementing Gotos/Loops): this.
10793 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
10795 Adjust to latest gnulib.
10796 * bootstrap (gnulib_modules): Add xalloc-die.
10797 Set LC_ALL=C so that file names sort consistently.
10798 Prefer the gnulib copies of gettext.m4, glibc21.m4,
10799 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
10800 uintmax_t.m4, ulonglong.m4.
10801 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
10802 po.m4 since we are now using _gl.m4 instead.
10804 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
10806 * src/scan-action.l: Remove. Scanning of semantic actions is
10807 handled in scan-gram.l.
10809 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
10811 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
10813 * src/location.h (struct): The file member is a uniqstr.
10814 (equal_boundaries): Use UNIQSTR_EQ for comparison.
10816 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
10818 Fix bug with non-%union parsers that have printers or destructors,
10819 which led to a Bison core dump. Reported by Peter Fales in
10820 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
10822 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
10823 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
10824 not to our own type.
10825 * src/output.c (symbol_destructors_output, symbol_printers_output):
10826 Don't assume %union.
10827 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
10828 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
10829 UNION-FLAG. All callers changed.
10830 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
10831 Use type char, not unsigned int, when declaring an array of char;
10832 this lets us remove a cast.
10833 (Printers and Destructors): Add non-%union test cases.
10835 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
10837 * doc/bison.texinfo: Minor editorial changes, mostly to the new
10838 GLR writeups. E.g., avoid frenchspacing and the future tense,
10839 change "lookahead" to "look-ahead", and change "wrt" to "with
10842 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
10844 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
10845 New sections, split off from the GLR Parsers section. Put the new
10846 Simple GLR Parser near the start of the GLR section, for clarity.
10847 Rewrite connective text.
10849 2004-06-21 Frank Heckenbach <frank@g-n-u.de>

10905 C++ compiler. (trivial change)
10907 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
10909 Spent a few hours checking out which prerequisite versions the
10910 current sources actually require. I went all the way back to
10911 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
10912 a seemingly endless set of combinations of versions more recent
10913 than that. The bottom line is that the current sources require
10914 fairly recent versions of the build tools, and it'll be some work
10916 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
10917 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
10918 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
10919 Add comments explaining why those particular versions are
10922 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
10923 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
10924 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
10926 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
10927 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
10929 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
10931 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
10932 0.11.5. Suggested by Bruno Haible.
10933 * bootstrap: Remove gettext version checking.
10935 * doc/bison.texinfo (Decl Summary): Also mention that %union
10936 can depend on prerequisite types. Problem reported by Tim
10939 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
10941 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
10942 * README-alpha: Don't tell people not to package this.
10944 * bootstrap: Don't assume $(...) works; use `...` instead.
10945 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
10948 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
10949 put into the -d output file, and mention what to do if YYSTYPE is
10950 defined as a macro.
10952 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
10954 Undo change made earlier today: it caused autopoint to not bring
10955 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
10958 * bootstrap: Check that gettext version matches what's in
10959 configure.ac. Warn users to ignore robots.txt ERROR 404.
10960 * bootstrap: Undo today's earlier change (logged below).
10961 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
10963 The gettext version checking is causing more trouble than it's
10964 curing; remove it. Problem reported by Paul Hilfinger.
10966 * bootstrap: Issue a warning that one can expect a message
10967 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
10968 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
10970 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
10972 Ensure that the C++ compiler used for testing actually works on a
10973 simple test program; if not, skip the C++-related tests. Problem
10974 reported by Vin Shelton in:
10975 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html

10982 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
10984 * data/glr.c (yylloc): Output this macro even if locations are not
10985 being generated, as the GLR parser needs it even in that case.
10986 Problem reported by Troy A. Johnson
10987 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
10989 * configure.ac (AC_INIT): Update to 1.875e.

10993 * NEWS: Version 1.875d.
10994 * configure.ac (AC_INIT): Likewise.
10995 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
10997 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
10998 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
10999 lalr1.cc runs afoul of the first, and the last two are no longer
11000 supported by GCC 3.4.0.
11001 * README: Mention GNU m4 1.4 or later; mention m4 patches.
11002 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
11004 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
11006 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not

11018 character and string literals.
11019 (unexpected_end): New function.
11020 (unexpected_eof): Use it.
11021 (unexpected_newline): New function.
11022 (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>): Coalesce duplicate
11025 * NEWS: Document %expect-rr.
11027 * bootstrap (--gnulib-srcdir=*, --cvs-user=*):
11028 Fix typo by replacing $1 with $option.
11029 Remove more 'intl'-related files.
11030 Don't DEFUN AM_INTL_SUBDIR twice.

11040 * src/.cvsignore: Add *.output.
11042 * src/parse-gram.y: Put copyright notice inside %{ %} so it
11043 gets copied to the output file.
11045 2004-04-28 Paul Eggert <eggert@twinsun.com>
11047 Get files from the gnulib and po repositories, instead of relying
11048 on them being in our CVS. Upgrade to latest versions of gnulib
11051 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
11052 * bootstrap: Bootstrap from gnulib and po repositories.
11053 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
11054 * README-cvs: Document these changes. Remove version numbers from
11055 mentions of build tools, since they change so often. Mention Flex.
11057 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
11058 (gl_USE_SYSTEM_EXTENSIONS): Add.
11059 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
11060 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
11062 (AC_ISC_POSIX): Remove; we no longer support this
11063 ancient OS, as it gets in the way of latest Autoconf & gnulib.
11064 (AC_HEADER_STDC): Remove: we now assume C89 or better.
11065 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
11066 Do not check for C89 headers, except for locale.h which is used
11067 by the Yacc library and must port to K&R hosts.
11068 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
11069 Do not check for C89 functions, except for setlocale which is
11070 used by the Yacc library.
11071 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.

11075 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
11076 AM_GNU_GETTEXT): Remove; now done by:
11077 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
11078 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
11081 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
11082 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
11083 Define to empty, as gnulib.mk will do the rest for us.
11084 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
11086 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
11087 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
11089 * src/files.c: Include gnulib's xstrndup.h.

11094 (strnlen, memrchr): Remove decls; functions no longer used.
11095 Include <stpcpy.h>.

11118 Remove, as these files are now generated automatically
11119 by bootstrap or automake.
11121 * po/ChangeLog: Remove: all but one entry was a duplicate
11122 of this file, and I moved that 2000-11-02 entry here.
11124 * config/.cvsignore: Add Makefile, depcomp, install-sh.
11125 * lib/.cvsignore: Add alloca.c, alloca.h, alloca_.h, argmatch.c,

11141 * src/.cvsignore: Remove *_.c.
11144 * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't
11145 support it. (The latest stable gzip doesn't.)
11147 2004-04-27 Paul Eggert <eggert@twinsun.com>
11149 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
11150 case, as stos_ is now used by destructors due to the 2004-02-09
11153 Remove more K&R C support.
11154 * lib/libiberty.y (PARAMS): Remove. All uses removed.

11165 unconditionally. Do not declare perror.

11172 with latest obstack.h.
11173 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
11174 to procedure types, as obstack.h now does that for us.
11175 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
11177 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
11178 so that this include file can stand alone.

11181 test whether it can stand alone.
11183 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
11184 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
11185 unused declaration.
11187 * tests/synclines.at (%union synch line): Put a dummy member in
11188 the union, because empty unions aren't allowed in C. Caught
11191 2004-04-13 Jim Meyering <jim@meyering.net>

11250 expected_conflicts.
11251 (expected_rr_conflicts): Define.
11252 (conflicts_print): Check r/r conflicts against expected_rr_conflicts
11254 Use expected_sr_conflicts in place of expected_conflicts.
11255 Warn if expected_rr_conflicts used in non-GLR parser.
11257 * doc/bison.texinfo: Add documentation for %expect-rr.
11259 2004-03-08 Paul Eggert <eggert@gnu.org>
11261 Add support for hex token numbers. Suggested by Odd Arild Olsen in
11262 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
11264 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
11266 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.

11270 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
11271 handle_action_dollar, handle_action_at, convert_ucn_to_byte):
11272 Say "long int", not "long", for uniformity with GNU style.
11274 2004-02-25 Paul Eggert <eggert@twinsun.com>
11276 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
11277 compilers. This fixes a problem with Intel's C++ compiler being
11278 chatty, reported by Guido Trentalancia in
11279 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
11281 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>
11283 Support %destructor and merge error locations in lalr1.cc.
11285 * data/lalr1.cc (b4_cxx_destruct_def): New macro.

11295 token so that it covers all the discarded tokens.
11296 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
11297 it can be called with `%skeleton "lalr1.cc"', and do that.
11299 2004-02-02 Paul Eggert <eggert@twinsun.com>
11301 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
11302 $(top_srcdir)/lib and ../lib. This fixes a bug reported
11303 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
11304 There's no need to mention top_builddir since Automake does that
11306 (INCLUDES): Remove, as Automake says it's obsolescent.
11307 Contents migrated into AM_CPPFLAGS as described above.
11308 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
11310 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
11312 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
11313 (yyreportSyntaxError): Handle case where lookahead token is
11316 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11318 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
11319 resulting parsers are compilable with C++.
11321 2003-12-23 Paul Eggert <eggert@twinsun.com>
11323 * config/depcomp, config/install-sh: Sync with Automake 1.8.
11324 * src/output.c (output_skeleton): Rename local var.
11325 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
11326 Bison tokens, as this runs afoul of the 2003-10-07 change that
11327 disallowed NUL bytes in character constants or string literals.
11329 * tests/local.at: Require Autoconf 2.59's Autotest.
11330 * tests/testsuite.at: Don't include local.at, since we now assume
11331 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
11333 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
11334 multiple inclusion warnings.
11336 2003-12-02 Akim Demaille <akim@epita.fr>

11348 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
11349 if testsuite doesn't exist.

11352 literals, unfortunately.
11353 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
11354 Complain about NUL bytes in character constants or string literals.
11356 2003-10-05 Paul Eggert <eggert@twinsun.com>
11358 * NEWS: Don't document %no-default-prec, as it's still
11360 * doc/bison.texinfo: Document %no-default-prec only if
11361 the defaultprec flag is set. Normally it's not.
11363 2003-10-04 Paul Eggert <eggert@twinsun.com>
11365 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
11366 non-modifiable lvalue, instead of a modifiable one.
11367 * doc/bison.texinfo (Actions): Document that $$ can
11368 be assigned to. Do not claim that $$ and $N are
11369 array element references: user code should not rely on this.
11371 2003-10-01 Paul Eggert <eggert@twinsun.com>
11373 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.

11403 a typo in the 2003-08-25 patch.
11405 2003-08-27 Akim Demaille <akim@epita.fr>
11407 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify

11419 Adjust: nerrs and errstatus is now replaced by...
11420 (Parser::nerrs_, Parser::errstatus_): New.
11422 2003-08-25 Akim Demaille <akim@epita.fr>
11424 * config/announce-gen, Makefile.cfg: New.

11427 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
11429 2003-08-25 Akim Demaille <akim@epita.fr>
11431 When reducing initial empty rules, Bison parser read an initial
11432 location that is not defined. This results in garbage, and that
11433 affects Bison's own parser. Therefore we need (i) to extend Bison
11434 to support a means to initialize this location, and (ii) to use
11435 this CVS Bison to fix CVS Bison's parser.
11437 * src/reader.h, reader.c (epilogue_augment): Remove, replace
11439 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.

11441 (%initial-action): New.
11442 (%error-verbose): Since we require CVS Bison, there is no reason
11444 * src/scan-gram.l: Adjust.
11445 * src/Makefile.am (YACC): New, to make sure we use our own parser.
11446 * data/yacc.c (yyparse): Use b4_initial_action.
11448 2003-08-25 Akim Demaille <akim@epita.fr>
11450 * doc/bison.texinfo: Don't promote stdout for error messages.
11452 2003-08-25 Akim Demaille <akim@epita.fr>
11454 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
11455 From Alexandre Duret-Lutz.

11468 * data/lalr1.cc (Parser::reduce_print_): New.
11471 2003-08-25 Akim Demaille <akim@epita.fr>
11473 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
11474 error recovery loops. This patch is based on
11475 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
11476 Also, augment the similarity between lalr1.cc and yacc.c.
11477 Note: the locations of error recovery rules are not correct yet.
11479 * data/lalr1.cc: Comment changes to augment the similarity between
11480 lalr1.cc and yacc.c.
11481 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
11482 (yyerrlab1): Remove, but where it used to be (now the bottom part of
11483 yyerrlab), when hitting EOF, pop the whole stack here instead of
11484 merely falling thru the default error handling mechanism.
11485 (yyerrorlab): New label, with the old contents of YYERROR,
11486 plus the following change: pop the stack of rhs corresponding
11487 to the production that invoked YYERROR. That is how Yacc
11488 behaves (required by POSIX).
11489 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
11492 2003-08-25 Akim Demaille <akim@epita.fr>
11494 Tune local.at so that people can "autom4te -l autotest calc.at -o
11495 calc" for instance, to extract a sub test suite.
11497 * tests/testsuite.at: Move the initialization, Autotest version
11498 requirement, and AT_TESTED invocation into...
11499 * tests/local.at: here.
11500 * tests/testsuite.at: Include it for compatibility with Autoconf
11502 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
11505 2003-08-04 Paul Eggert <eggert@twinsun.com>
11507 Rework code slightly to avoid gcc -Wtraditional warnings.
11508 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
11509 The returned value is now stored in *YY0. All callers changed.
11510 * src/output.c (merge_output): Adjust to the above change.
11512 2003-07-26 Paul Eggert <eggert@twinsun.com>
11514 * data/glr.c (YYASSERT): New macro.
11515 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
11516 yyresolveStates, yyprocessOneStack):
11517 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
11518 Derived from a suggestion by Frank Heckenbach.
11520 2003-07-25 Paul Eggert <eggert@twinsun.com>
11522 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
11523 for portability to K&R C (after ansi2knr, presumably). See
11524 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
11525 by Frank Heckenbach, though I have omitted the structure-initialization
11526 part of his glr-knr.diff patch since I recall that the Portable
11527 C Compiler didn't require that change.
11529 Let the user specify how to allocate and free memory.
11530 Derived from a suggestion by Frank Heckenbach in
11531 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
11532 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
11533 All uses of free, malloc, realloc changed to use these macros,
11534 and unnecessary casts removed.
11535 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
11537 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
11539 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
11540 use s.empty() rather than s == "" to test for empty string; see
11541 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
11544 2003-06-25 Akim Demaille <akim@epita.fr>

11550 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
11551 and return properly parenthesized result.

11560 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
11561 yyreportTree): Do not assume that size_t is the same width as int,
11562 when printing sizes. Print sizes using an unsigned format.
11563 Problem reported by Frank Heckenbach in
11564 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
11566 Port to Forte Developer 7 C compiler.
11567 * data/glr.c (struct YYLTYPE): If locations are not being used,
11568 declare a single dummy member, as empty structs do not conform
11570 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
11571 the Forte Developer 7 C compiler complains that end-of-loop
11572 code is not reached.

11587 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
11588 Don't use 'index' in comments, as it's a builtin fn on some hosts.

11590 per recent gettext manual's suggestion.
11591 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
11592 Use prototypes, not old-style definitions.
11593 * lib/lbitset.c (lbitset_unused_clear): Likewise.

11616 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
11617 `How Can I Reset @code{yyparse}', since texinfo does not allow
11618 arbitrary @ in node names.
11620 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
11621 shouldn't be needed according to the gettext 0.12.1 documentation
11622 but which seem to be needed anyway: codeset.m4 glibc21.m4
11623 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
11624 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.

11647 the tests right now.
11648 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
11649 yyerror are declared before use; C99 requires this.

11653 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
11655 (yyrecoverSyntaxError): Correct the logic for setting and testing
11657 Correct comment on handling EOF.
11658 Allow states with only a default reduction, rather than failing
11659 (I can't quite reconstruct why these were not allowed before).
11661 Fixes to avoid problem that $-N rules in GLR parsers can cause
11662 buffer overruns, corrupting state.
11664 * src/output.c (prepare_rules): Output max_left_semantic_context
11666 * src/reader.h (max_left_semantic_context): New variable declaration.

11681 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
11683 * tests/cxx-type.at: Exercise location information; update tests
11684 to differentiate output with and without locations.
11685 Remove forward declarations of yylex and yyerror---caused errors
11686 because default YYLTYPE not yet defined.
11687 Change semantic actions to compute strings, rather than printing
11688 them directly (to test proper passing of semantics values). Change
11689 output to prefix notation and update test data and expected results.
11690 (yylex): Track locations.
11691 (stmtMerge): Return value rather than printing, and include arguments

11696 Avoid warnings generated by GCC 2.95.4 when Bison is
11697 configured with --enable-gcc-warnings.
11698 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
11699 yy::]b4_parser_class_name[::translate_,
11700 yy::Stack::operator[] (unsigned),
11701 yy::Stack::operator[] (unsigned) const,
11702 yy::Slice::operator[] (unsigned),
11703 yy::Slice::operator[] (unsigned) const):
11704 Rename local vars to avoid warnings.
11705 * tests/glr-regression.at (Improper handling of embedded actions
11706 and $-N in GLR parsers): Remove unused local variable from yylex.
11707 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
11708 (void) as arg when not pure, since we now assume C89 when building
11709 Bison. Pacify GCC by using parameter.
11711 2003-06-02 Paul Eggert <eggert@twinsun.com>
11713 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
11714 yy::Location::lines, yy::Location::columns): Rename arguments
11715 to avoid shadowing; this removes a warning generated by GCC 3.3.
11717 2003-06-01 Paul Eggert <eggert@twinsun.com>
11719 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
11720 to g++, as GCC 3.3 complains if you do it.
11721 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
11722 everything that WARNING_CFLAGS has, except omit warnings
11723 not suitable for C++.
11724 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
11725 * tests/atlocal.in (CXXFLAGS): New var.
11726 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
11728 Fix a GLR parser bug I reported in February; see
11729 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
11730 The problem was that GLR parsers did not conform to the C standard,
11731 because actions like { $1 = $2 + $3; } expanded to expressions
11732 that invoked YYFILL in separate subexpressions, and YYFILL assigned
11733 to a local variable. The C standard says that expressions
11734 like (var = f ()) + (var = f ()) have undefined behavior.
11735 Another problem was that GCC sometimes issues warnings that
11736 yyfill and its parameters are unused.
11738 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
11739 as possibly unused.
11740 (yyfill): New function.
11742 (yyuserAction): Change type of yynormal to bool, so that it matches
11743 the new yyfill signature. Mark it as possibly unused.
11746 Follow up on a bug I reported in February, where a Bison-generated
11747 parser can loop. Provide a test case and a fix for yacc.c. I
11748 don't have a fix for lalr1.cc or for glr.c, unfortunately.
11749 The original bug report is in:
11750 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
11752 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
11753 macro's size was becoming unwieldy.
11754 (yyerrlab): Do not discard an empty lookahead symbol, as this
11755 might destroy garbage.
11756 (yyerrorlab): New label, with the old contents of YYERROR,
11757 plus the following change: pop the stack of rhs corresponding
11758 to the production that invoked YYERROR. That is how Yacc
11759 behaves, and POSIX requires this behavior.
11760 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
11761 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
11762 Define 'alarm' to do nothing if unistd.h is not available.
11763 Add a new rule "exp: '-' error;" to test the above change to
11764 data/yacc.c. Use 'alarm' to abort any test taking longer than
11765 10 seconds, as it's probably looping.
11766 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
11767 Also, the new yacc.c generates two fewer diagnostics for an
11770 2003-05-24 Paul Eggert <eggert@twinsun.com>
11772 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
11773 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
11774 This fixes a problem reported by John Bowman when the Compaq/HP
11775 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
11776 -ansi -Wall -gall).
11777 * data/yacc.c (union yyalloc): Likewise.
11778 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
11780 Switch from 'int' to 'bool' where that makes sense.

11785 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
11786 Return or accept bool, not int. All callers changed.

11806 lbitset_xor_cmp): Likewise.
11807 * lib/bbitset.h: Include <stdbool.h>.
11808 (struct bitset_vtable): The following members now return bool, not
11809 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
11810 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
11812 * src/conflicts.c (count_rr_conflicts): Likewise.

11832 * src/tables.c (action_row, pack_vector): Likewise.
11833 * src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro.
11834 * src/output.c (prepare): Use it.
11835 * src/output.c (token_definitions_output,
11836 symbol_destructors_output, symbol_destructors_output): Use string,
11837 not boolean integer, to keep track of whether to output separator.
11838 * src/print_graph.c (print_core): Likewise.
11839 * src/state.c (state_rule_lookaheads_print): Likewise.
11841 * config/install-sh: Sync from automake 1.7.5.
11843 2003-05-14 Paul Eggert <eggert@twinsun.com>
11845 * src/parse-gram.y (rules_or_grammar_declaration): Require a
11846 semicolon after a grammar declaration, in the interest of possible
11847 future changes to the Bison input language.
11848 Do not allow a stray semicolon at the start of the grammar.
11849 (rhses.1): Allow one or more semicolons after any rule, including
11850 just before "|" as required by POSIX.
11851 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
11854 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
11856 %parse-param support for lalr1.cc.
11858 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
11859 b4_cc_constructor_calls, b4_cc_constructor_call,
11860 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
11862 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
11863 parse-param arguments.
11864 (yy::b4_parser_class_name): Declare instance variables to
11865 hold parse-param arguments.
11866 * tests/calc.at: s/value/semantic_value/ because value clashes
11867 with a member of yy::b4_parser_class_name. Adjust C++ code
11868 to handle %parse-param. Enable %parse-param test in C++.
11870 2003-05-12 Paul Eggert <eggert@twinsun.com>
11872 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
11873 English a bit. Fix fclose typo. Change "const char" to "char
11874 const", and use ANSI C rather than K&R for "main". Suggest
11875 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
11876 and suggest yy_switch_to_buffer.
11878 2003-05-05 Paul Eggert <eggert@twinsun.com>
11880 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
11881 C89. This avoids a diagnostic on compilers that define __STDC__
11882 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
11883 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
11885 2003-05-03 Paul Eggert <eggert@twinsun.com>
11887 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
11888 Do not overrun array bounds.
11889 This should fix a bug reported today by Olatunji Oluwabukunmi in
11890 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
11892 2003-04-29 Akim Demaille <akim@epita.fr>
11894 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
11895 * src/getargs.c, src/getargs.h: here, as bool, not int.
11896 (nondeterministic_parser): New.
11897 * src/parse-gram.y, src/scan-gram.l: Support
11898 %nondeterministic-parser.
11899 * src/output.c (prepare): Use nondeterministic_parser instead
11900 of glr_parser where appropriate.
11901 * src/tables.c (conflict_row, action_row, save_row)
11902 (token_actions, token_actions, pack_vector): Ditto.
11904 2003-04-29 Akim Demaille <akim@epita.fr>
11906 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
11908 2003-04-29 Akim Demaille <akim@epita.fr>
11910 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
11911 with %pure-parser and %locations to exercise the patch from Yakov
11914 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
11916 * data/yacc.c: (b4_lex_param): Corrected for the case where
11917 %lex-param is provided and %pure-parser isn't.
11919 2003-04-27 Paul Eggert <eggert@twinsun.com>
11921 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
11922 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
11923 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
11924 if it is not defined.
11925 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
11927 2003-04-26 Paul Eggert <eggert@twinsun.com>
11929 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
11930 Declare to be of type suitable for the ninf value itself, not of
11931 type suitable for the corresponding table, since the latter might
11932 be unsigned but the ninf value might be negative. This fixes a
11933 bug reported by Alexandre Duret-Lutz in
11934 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
11936 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
11937 invokes it. We shouldn't invoke it twice because it will attempt
11938 to put error.o in the archive twice. This fixes a glitch reported
11939 by Martin Mokrejs in
11940 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
11942 2003-04-21 Paul Eggert <eggert@twinsun.com>
11944 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
11947 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
11949 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
11950 Fix obvious typo that results in uncompilable GLR parsers
11951 when both %pure-parser and %locations are used. (trivial change)
11953 2003-04-17 Paul Eggert <eggert@twinsun.com>
11955 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
11956 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
11957 Do not insert the expected token via unput, as this runs afoul
11958 of a POSIX-compatibility bug in flex 2.5.31.
11959 All uses changed to BEGIN the parent state,
11960 since we no longer insert the expected token via unput.
11961 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
11962 that is no longer emitted after the above change.
11964 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
11965 the first one. This change is from Paul Hilfinger, and it fixes
11966 regression reported by Werner Lemberg in
11967 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
11969 (resolve_sr_conflict): Don't invoke state_errs_set
11970 unless one or more tokens have been explicitly made errors.
11971 Otherwise, the above change causes Bison to abort.
11973 * tests/existing.at (GNU pic Grammar): New test case, taken from
11976 2003-03-31 Akim Demaille <akim@epita.fr>
11978 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
11980 2003-03-31 Akim Demaille <akim@epita.fr>
11982 * src/output.c (prepare_symbols): Avoid trailing spaces in the
11985 2003-03-31 Akim Demaille <akim@epita.fr>
11987 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
11988 From Paul Hilfinger.
11990 2003-03-29 Akim Demaille <akim@epita.fr>
11992 * m4/error.m4: Do not put under dynamic conditions some code which
11993 expansion is under static control.
11995 2003-03-29 Akim Demaille <akim@epita.fr>
11997 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
11999 2003-03-29 Akim Demaille <akim@epita.fr>
12001 * doc/bison.texinfo (Strings are Destroyed): New.
12003 2003-03-13 Paul Eggert <eggert@twinsun.com>
12005 * .cvsignore: Add configure.lineno.
12006 * src/.cvsignore: Add yacc.
12007 * tests/.cvsignore: Add testsuite.log.
12008 * doc/fdl.texi: Sync with latest FSF version.
12010 2003-03-12 Paul Eggert <eggert@twinsun.com>
12012 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
12013 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
12014 cursor, instead of leaving it undefined. This fixes a bug
12015 reported by Tim Van Holder in
12016 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
12017 * tests/input.at (Torturing the Scanner): Test the scanner on
12018 an empty input file, which was Tim Van Holder's test case.
12020 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
12021 <sys/resource.h> can be included, include sys/time.h and
12022 sys/times.h first, if available. This works around the SunOS
12023 4.1.4 porting bug reported by Bruce Becker in
12024 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
12026 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
12027 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
12028 AC_HEADER_SYS_WAIT.
12030 Merge changes from gnulib. This was prompted because the CVS
12031 snapshot didn't build on Solaris 7 due to strnlen problems.
12033 These changes need to be merged back into gnulib:
12034 * lib/hash.c: Include <stdbool.h> unconditionally.
12035 * m4/onceonly.m4 (m4_quote): New macro.
12036 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
12037 Quote AC_FOREACH variable-expansions properly.
12038 The 2003-01-03 obstack.h change also needs merging.
12039 {end of changes requiring merging}
12041 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
12042 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,

12045 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
12046 New files, imported from gnulib.
12047 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
12050 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
12051 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
12054 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
12056 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
12057 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
12058 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
12059 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
12060 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
12061 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
12062 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
12063 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
12064 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
12065 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
12066 (jm_PREREQ_ARGMATCH): Remove.
12067 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
12068 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
12070 * src/system.h: Include <stdbool.h> unconditionally.
12072 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
12073 assuming at least C89 in the bitset code for some time now.
12075 2003-03-03 Akim Demaille <akim@epita.fr>
12079 2003-03-02 Akim Demaille <akim@epita.fr>
12081 * doc/bison.texinfo (Table of Symbols): Reactivate the
12082 documentation for %lex-param, and %parse-param.
12084 2003-03-02 Akim Demaille <akim@epita.fr>
12086 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
12087 generate verbose error messages.
12088 Use the number of tokens as an upper bound in yytname, as it
12089 cannot be a non terminal.
12091 2003-03-02 Akim Demaille <akim@epita.fr>
12093 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
12096 2003-03-02 Akim Demaille <akim@epita.fr>
12098 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
12099 Use them to exercise yycheck overrun.
12100 Based on Andrew Suffield's grammar.
12102 2003-03-02 Akim Demaille <akim@epita.fr>
12104 Create tests/local.at for Bison generic testing macros.
12106 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
12107 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
12109 * tests/calc.at (AT_CHECK_CALC): Adjust.
12110 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
12111 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
12112 * tests/local.at: here.
12113 (AT_COMPILE_CXX): Tags the tests using it as c++.
12114 Ignore the test if CXX is not functional.
12116 2003-03-01 Paul Eggert <eggert@twinsun.com>
12118 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
12119 not loc->end, since loc->end might contain garbage and this leads
12120 to undefined behavior on some platforms.
12121 (id_loc, token_start): Use (IF_LINTed) initial values that do not
12122 depend on *loc, so that the reader doesn't give the the false
12123 impression that *loc is initialized.
12124 (<INITIAL>"%%"): Do not bother setting code_start, since its value
12125 does not survive the return.
12127 2003-03-01 Akim Demaille <akim@epita.fr>
12129 * src/scan-gram.l (code_start): Always initialize it when entering
12130 into yylex, as SC_EPILOGUE is activated *before* the corresponding
12131 yylex invocation. An alternative would be making it static, but
12132 then it starts with the second %%'s beginning, instead of its end.
12134 2003-02-28 Paul Eggert <eggert@twinsun.com>
12136 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
12137 around a UnixWare 7.1.1 porting bug reported by John Hughes in
12138 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
12140 2003-02-26 Paul Eggert <eggert@twinsun.com>
12142 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
12143 Remove Sequent/Pyramid discussion (nobody uses them any more).
12144 Merge VMS and MS-DOS discussion; these ports may well be dead
12145 but let's keep mentioning them for now. Put <> around email
12146 addresses. Add copyright notice.
12148 2003-02-24 Paul Eggert <eggert@twinsun.com>
12150 * data/glr.c (yy_reduce_print): yylineno -> yylno,
12151 to avoid collision with flex use of yylineno.
12152 Problem reported by Bruce Lilly in
12153 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
12154 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.

12157 * config/depcomp: Sync with Automake 1.7.3.
12159 2003-02-21 Akim Demaille <akim@epita.fr>
12161 * data/lalr1.cc: Use temporary variables instead of casts to
12162 change integer types.
12163 Suggested by Paul Eggert.
12165 2003-02-21 Akim Demaille <akim@epita.fr>
12167 * doc/bison.texinfo: Use "location" consistently to refer to @n,
12168 to avoid confusions with lalr1.cc's notion of Position.
12169 Suggested by Paul Eggert.
12171 2003-02-20 Akim Demaille <akim@epita.fr>
12173 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
12174 before initial_columns.
12175 (location.hh): Use consistent variable names when defining the
12177 Use "last" so that we subtract from Positions, not from unsigned.
12179 2003-02-20 Akim Demaille <akim@epita.fr>
12181 * data/lalr1.cc (position.hh): New subfile, including the extended
12182 and Doxygen'ed documentation of class Position.
12183 (location.hh): Use it.
12184 Document a` la Doxygen.
12185 With the help of Benoit Perrot.
12187 2003-02-20 Akim Demaille <akim@epita.fr>
12189 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
12191 Redefine AT_YYERROR_SEES_LOC_IF using it.
12192 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
12194 Don't use the location in yy::Parser::error_ and
12195 yy::Parser::print_ when not %locations.
12196 Activate more lalr1.cc tests.
12198 2003-02-19 Akim Demaille <akim@epita.fr>
12200 * data/lalr1.cc: When displaying a line number, be sure to make it
12203 2003-02-19 Akim Demaille <akim@epita.fr>
12205 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
12207 (YYABORT, YYACCEPT, YYERROR): New.
12208 * tests/calc.at: Renable the lalr1.cc test.
12210 2003-02-19 Akim Demaille <akim@epita.fr>
12212 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
12213 error recovery, mixing with/without pops and discarding of the
12216 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
12218 2003-02-17 Paul Eggert <eggert@twinsun.com>
12220 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
12221 * tests/testsuite.at (AT_COMPILE): Use them.
12222 This fixes the testsuite problem reported by Robert Lentz in
12223 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
12225 2003-02-12 Paul Eggert <eggert@twinsun.com>
12227 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
12228 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
12229 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
12230 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
12231 Check for malloc failure, for consistency with yacc.c.
12232 (yytname_size): Remove, for consistency with yacc.c.
12234 The bug still remains in data/lalr1.cc, as I didn't have time
12237 2003-02-06 Akim Demaille <akim@epita.fr>
12239 * configure.ac (GXX): Rename as...
12240 (CXX): this, to keep the original Autoconf semantics.
12242 * data/lalr1.cc: Fix b4_copyright invocations.
12243 If YYDEBUG is not defined, don't depend upon name_ being defined.
12244 (location.hh): Include string and iostream.
12245 (Position::filename): New member.
12246 (Position::Position ()): New.
12247 (operator<< (Position)): New.
12248 (operator- (Position, int)): New.
12249 (Location::first, Location::last): Rename as...
12250 (Location::begin, Location::end): these, to mock the conventional
12252 (operator<< (Location)): New.
12253 * tests/atlocal.in (CXX): New.
12254 * tests/testsuite.at (AT_COMPILE_CXX): New.
12255 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
12256 locations in a more synthetic way.
12257 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
12259 Adjust the C locations to match those from Emacs: first column is
12261 Change all the expected results.
12262 Conform to the GCS: simplify the locations when applicable.
12263 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
12264 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
12265 these CPP macros with the m4 macros new defined by...
12266 (AT_CHECK_PUSHDEFS): this, i.e.:
12267 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
12268 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
12270 (AT_CHECK_POPDEFS): Undefine them.
12271 (AT_CHECK_CALC_LALR1_CC): New.
12272 Use it for the first lalr1.cc test.
12274 2003-02-04 Akim Demaille <akim@epita.fr>
12276 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
12277 Location as is defined.
12279 2003-02-04 Akim Demaille <akim@epita.fr>
12281 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
12282 name_ being defined.
12284 2003-02-03 Paul Eggert <eggert@twinsun.com>
12286 * src/gram.h (start_symbol): Remove unused decl.
12288 Use more-consistent naming conventions for local vars.
12290 * src/derives.c (derives_compute): Change type of local var from
12291 int to rule_number.
12292 * src/gram.c (grammar_rules_partial_print): Likewise.
12293 * src/print.c (print_core): Likewise.
12294 * src/reduce.c (reduce_grammar_tables): Likewise.
12296 * src/gram.c (grammar_dump): Change name of item_number *
12297 local var from r to rp.
12298 * src/nullable.c (nullable_compute): Likewise.
12300 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
12302 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
12303 for symbol or symbol_number var.
12304 * src/reader.c (grammar_start_symbol_set): Likewise.
12305 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
12307 * src/state.c (transitions_to): Likewise.
12308 * src/state.h: Likewise.
12309 * src/tables.c (symbol_number_to_vector_number): Likewise.
12311 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
12314 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
12317 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
12320 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
12321 Use str, not s, for char * var. Use ch, not c, for character var.
12322 Use size for size var.
12324 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
12326 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
12328 * src/uniqstr.h: Likewise.
12330 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
12331 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
12332 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
12333 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
12334 param to have same name as that of enum, so that we don't use
12335 "s" to stand for a non-state.
12337 2003-02-02 Akim Demaille <akim@epita.fr>
12339 * src/scan-skel.l: Scan more than one inert character per yylex
12342 2003-02-01 Paul Eggert <eggert@twinsun.com>
12346 * po/LINGUAS: Add ms.
12348 2003-01-30 Akim Demaille <akim@epita.fr>
12350 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
12352 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12354 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
12357 Changes in response to error report by S. Eken: GLR mode does not
12358 handle negative $ indices or $ indices in embedded rules correctly.
12359 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
12361 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
12362 (b4_rhs_location): Ditto.
12363 (yyfill): New function to copy from stack tree into array
12365 (yyuserAction): Modify to allow incremental move of semantic values
12366 to rhs array when in GLR mode.
12367 Define YYFILL to use in user-defined actions to fill semantic array
12369 Remove dummy use of yystack, as there is now a guaranteed use.
12370 (yydoAction): Modify to allow incremental move of semantic values
12371 to rhs array when in GLR mode.
12372 (yyresolveAction): Ditto.
12373 (yyglrShiftDefer): Update comment.
12374 (yyresolveStates): Use X == NULL for pointers, not !X.
12375 (yyglrReduce): Ditto.
12376 (yydoAction): Ditto
12378 * tests/glr-regr1.at: Rename to ...
12379 * tests/glr-regression.at: Add new regression test for the problems
12380 described above (adapted from S. Eken).
12381 Update copyright notice.
12382 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
12383 * tests/Makefile.am: Ditto.
12385 2003-01-28 Paul Eggert <eggert@twinsun.com>
12387 * data/lalr1.cc: Do not use @output_header_name@ unless
12388 b4_defines_flag is set. This fixes two bugs reported by
12390 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
12391 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
12393 2003-01-21 Paul Eggert <eggert@twinsun.com>
12395 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
12396 we don't need to worry about yyerrlab1 being reported as an
12397 "unused label" by non-GCC C compilers. The downside is that if
12398 locations are used then a couple of statements are duplicated each
12399 time YYERROR is invoked, but the upside is that the warnings
12401 (yyerrlab1): Move code to YERROR.
12402 (yyerrlab2): Remove. Change uses back to yyerrlab1.
12403 This reverts some of the 2002-12-27 change.
12405 2003-01-17 Paul Eggert <eggert@twinsun.com>
12407 * src/output.c (symbol_printers_output): Fix typo that led
12408 to core dump. Problem reported by Antonio Rus in
12409 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
12411 2003-01-13 Akim Demaille <akim@epita.fr>,
12412 Quoc Peyrot <chojin@lrde.epita.fr>,
12413 Robert Anisko <anisko_r@lrde.epita.fr>
12415 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
12416 when the stacks contain one element, as the loop would otherwise
12417 free the last state, and then use the top state (the one we just
12418 popped). This means that the initial elements will not be freed
12419 explicitly, as is the case in yacc.c; it is not a problem, as
12420 these elements have fake values.
12422 2003-01-11 Paul Eggert <eggert@twinsun.com>
12424 * NEWS: %expect-violations are now just warnings, reverting
12425 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
12426 bootstrapping problem reported by Matthias Klose; see
12427 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
12428 * src/conflicts.c (conflicts_print): Likewise.
12429 * tests/conflicts.at (%expect not enough, %expect too much,
12430 %expect with reduce conflicts): Likewise.
12431 * doc/bison.texinfo (Expect Decl): Document this. Also mention
12432 that the warning is enabled if the number of conflicts changes
12433 (not necessarily increases).
12435 * src/getargs.c (version): Update copyright year.
12437 2003-01-09 Akim Demaille <akim@epita.fr>
12439 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
12441 2003-01-08 Paul Eggert <eggert@twinsun.com>
12443 * Makefile.maint (WGETFLAGS):
12444 New macro, containing "-C off" to disable proxy caches.
12445 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
12446 (rel-check): Use $(WGET) instead of wget.
12448 2003-01-06 Paul Eggert <eggert@twinsun.com>
12450 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
12451 the GLR paper of Scott, Johnstone and Hussain.
12453 2003-01-04 Paul Eggert <eggert@twinsun.com>
12455 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
12456 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
12457 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
12458 (EXTRA_LIBRARIES): New var, for liby.a.
12459 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
12460 (EXTRA_SCRIPTS): New var, for yacc.
12462 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
12463 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
12464 Problem reported by Nelson H. F. Beebe.
12466 2003-01-03 Paul Eggert <eggert@twinsun.com>
12468 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
12469 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
12470 when compiling Bison 1.875's `bitset bset = obstack_alloc
12471 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
12473 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
12474 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
12475 grow to a huge size with typical invocation.
12477 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
12478 Use the pattern recommended by Autoconf 2.57, except also protect
12479 against double-definition.
12480 * src/system.h: Likewise.
12481 Portability issues reported by Nelson H. F. Beebe.
12483 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
12484 All uses changed. Provide a definition in both C and C++.
12485 (yytrue, yyfalse): Define even if defined (__cplusplus).
12487 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
12488 Reported by Nelson H. F. Beebe.
12490 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
12492 2003-01-02 Paul Eggert <eggert@twinsun.com>
12494 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
12495 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
12496 Bug reported by Nelson H. F. Beebe.
12498 2003-01-01 Paul Eggert <eggert@twinsun.com>
12502 2002-12-30 Paul Eggert <eggert@twinsun.com>
12504 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
12506 (<INITIAL>","): Here. This causes stray "," to be treated
12509 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
12510 last brace in braced code when not in Yacc mode, for compatibility
12511 with Bison 1.35. This resurrects the 2001-12-15 patch to
12514 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
12515 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
12517 2002-12-28 Paul Eggert <eggert@twinsun.com>
12519 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
12520 that of SYM's type. This fixes Debian bug 168069, reported by
12523 2002-12-28 Paul Eggert <eggert@twinsun.com>
12527 Switch back to the Yacc style of conflict reports, undoing some
12528 of the 2002-07-30 change.
12529 * doc/bison.texinfo (Understanding): Use Yacc style for
12530 conflict reports. Also, use new way of locating rules.
12531 * src/conflicts.c (conflict_report):
12532 Renamed from conflict_report_yacc, removing the old
12533 'conflict_report'. Translate the entire conflict report at once,
12534 so that we don't assume that "," has the same interpretation in
12536 (conflicts_output): Use Yacc-style conflict report for each state,
12537 instead of our more-complicated style.
12538 (conflicts_print): Use Yacc-style conflict report, except print
12539 the input file name when not emulating Yacc.
12540 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
12541 Conflicted Reduction, %expect not enough, %expect too much,
12542 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
12543 * tests/existing.at (GNU Cim Grammar): Likewise.
12544 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
12546 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
12547 fatal): Don't invoke fflush; it's not needed and it might even be
12548 harmful for stdout, as stdout might not be open.
12549 * src/reduce.c (reduce_print): Likewise.
12551 2002-12-27 Paul Eggert <eggert@twinsun.com>
12553 Fix a bug where error locations were not being recorded correctly.
12554 This problem was originally reported by Paul Hilfinger in
12555 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
12557 * data/yacc.c (yyparse): New local var yylerrsp, to record the
12558 top of the location stack's error locations.
12559 (yyerrlab): Set it. When discarding a token, push its location
12560 onto yylerrsp so that we don't lose track of the error's end.
12561 (yyerrlab1): Now is only the target of YYERROR, so that we can
12562 properly record the location of the action that failed. For GCC
12563 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
12564 GCC warning about yyerrlab1 being unused if YYERROR is unused.
12565 (yyerrlab2): New label, which yyerrlab now falls through to.
12566 Compute the error's location by applying YYLLOC_DEFAULT to
12567 the locations of all the symbols that went into the error.
12568 * doc/bison.texinfo (Location Default Action): Mention that
12569 YYLLOC_DEFAULT is also invoked for syntax errors.
12570 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
12571 Error locations include the locations of all the tokens that were
12572 discarded, not just the last token.
12574 2002-12-26 Paul Eggert <eggert@twinsun.com>
12576 * src/files.c: Include quote.h.
12577 (compute_output_file_names): Warn if we detect conflicting
12578 outputs to the same file. This should catch the misunderstanding
12579 exemplified by Debian Bug 165349, reported by Bruce Stephens..
12581 * src/conflicts.c (conflicts_print): If the user specifies
12582 "%expect N", report an error if there are any reduce/reduce
12583 conflicts. This is what the manual says should happen.
12584 This fixes Debian bug 130890, reported by Anthony DeRobertis.
12585 * tests/conflicts.at (%expect with reduce conflicts): New test.
12587 Don't use m4_include on relative file names, as it doesn't work as
12588 desired if there happens to be a file with that name under ".".
12590 * m4sugar/version.m4: Remove; it was included but it wasn't used.
12591 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
12592 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
12593 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
12594 * src/output.c (output_skeleton): Use full path names when
12595 specifying a file to include; don't rely on include path, as
12596 it's unreliable when the working file contains a file with
12599 2002-12-25 Paul Eggert <eggert@twinsun.com>
12601 Remove obsolete references to bison.simple and bison.hairy.
12602 Problem mentioned by Aubin Mahe in
12603 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
12604 * data/glr.c: Comment fix.
12605 * doc/bison.1: Remove references. Also, mention "yacc".
12607 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
12610 * src/parse-gram.y (declaration): Use enum "report_states" rather
12611 than its numeric value 1.
12613 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
12614 opening a new one. This fixes Debian bug 165349, reported by
12617 2002-12-24 Paul Eggert <eggert@twinsun.com>
12621 * Makefile.maint (cvs-update): Don't assume that the shell
12622 supports $(...), as Solaris sh doesn't.
12624 * src/parse-gram.y (lloc_default): Remove test for empty
12625 nonterminals at the end, since it didn't change the result.
12627 2002-12-24 Paul Eggert <eggert@twinsun.com>
12629 If the user does not define YYSTYPE as a macro, Bison now declares it
12630 using typedef instead of defining it as a macro. POSIX requires this.
12631 For consistency, YYLTYPE is also declared instead of defined.
12633 %union directives can now have a tag before the `{', e.g., the
12634 directive `%union foo {...}' now generates the C code
12635 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
12636 The default union tag is `YYSTYPE', for compatibility with Solaris 9
12637 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
12638 instead of `yyltype'.
12640 `yystype' and `yyltype' are now obsolescent macros instead of being
12641 typedefs or tags; they are no longer documented and will be
12642 withdrawn in a future release.
12644 * data/glr.c (b4_location_type): Remove.
12645 (YYSTYPE): Renamed from yystype.
12646 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
12647 (struct YYLTYPE): Renamed from struct yyltype.
12648 (YYLTYPE): Renamed from yyltype.
12649 (yyltype, yystype): New (and obsolescent) macros,
12650 for backward compatibility.
12651 * data/yacc.c: Likewise.
12653 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
12654 does not specify a union tag. This is for compatibility with
12657 * src/parse-gram.y (add_param): 2nd arg is now char * not char
12658 const *, since it is now modified by stripping surrounding { }.
12659 (current_braced_code): Remove.
12660 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
12661 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
12662 trailing " {...}". Now of type <chars>.
12663 (grammar_declaration): Adjust to bundled tokens.
12664 (code_content): Remove; stripping is now done by add_param.
12665 (print_token_value): Print contents of bundled tokens.
12666 (token_name): New function.
12668 * src/reader.h (braced_code, current_braced_code): Remove.
12669 (token_name): New decl.
12671 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
12672 token_type, not braced_code code_kind. All uses changed.
12673 (SC_PRE_CODE): New state, for scanning after a keyword that
12674 has (or usually has) an immediately-following braced code.
12675 (token_type): New local var, to keep track of which token type
12676 to return when scanning braced code.
12677 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
12678 <INITIAL>"%parse-param", <INITIAL>"%printer",
12679 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
12680 instead of returning a token type immediately.
12681 (<INITIAL>"{"): Set token type.
12682 (<SC_BRACED_CODE>"}"): Use it.
12683 (handle_action_dollar, handle_action_at): Now returns bool
12684 indicating success. Fail if ! current_rule; this prevents a core dump.
12685 (handle_symbol_code_dollar, handle_symbol_code_at):
12686 Remove; merge body into caller.
12687 (handle_dollar, handle_at): Complain in invalid contexts.
12689 * NEWS, doc/bison.texinfo: Document the above.
12690 * NEWS: Fix years and program names in copyright notice.
12692 2002-12-17 Paul Eggert <eggert@twinsun.com>
12694 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
12695 Reporting, Table of Symbols): Omit mentions of %lex-param and
12696 %parse-param from the documentation for now.
12698 2002-12-15 Paul Eggert <eggert@twinsun.com>
12700 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
12701 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
12702 lookahead symbol, and which sets yychar in parser actions) and it
12703 disagreed with the Bison documentation. Bug
12704 reported by Andrew Walrond.
12706 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
12707 as the caller now does that.
12708 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
12709 (YYEMPTY): Parenthesize right hand side, since others use it.
12710 (yyparse): Don't assume that our generated code is the only code
12713 2002-12-13 Paul Eggert <eggert@twinsun.com>
12717 POSIX requires a "yacc" command.
12718 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
12719 (MOSTLYCLEANFILES): Add yacc.
12721 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
12722 as an alias for bison y.
12724 * po/LINGUAS: Add da.
12726 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
12727 problem with latest <getopt.h>.
12728 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
12730 * doc/fdl.texi: Upgrade to 1.2.
12731 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
12732 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
12733 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
12735 * config/install-sh: Sync with autotools.
12737 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
12738 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
12739 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
12740 locations are requested.
12741 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
12742 locations are requested.
12744 2002-12-12 Paul Eggert <eggert@twinsun.com>
12746 Remove unportable casts and storage allocation tricks.
12747 While we're at it, remove almost all casts, since they
12748 usually aren't needed and are a sign of trouble.
12750 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
12752 * src/derives.c (derives_compute): Do not subtract NTOKENS from
12753 the pointer DSET returned by malloc; this isn't portable.
12754 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
12755 Similarly for DERIVES.
12756 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
12757 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
12758 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
12760 * src/derives.c (derives_compute): Do not bother invoking
12761 int_of_rule_number, since rule numbers are integers.
12763 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
12764 rather than XMALLOC (char, N).
12766 * src/files.c (filename_split): Rewrite to avoid cast.
12768 * src/gram.h (symbol_number_as_item_number,
12769 item_number_as_symbol_number, rule_number_as_item_number,

12771 Now inline functions rather than macros, to avoid casts.
12772 * src/state.h (state_number_as_int): Likewise.
12773 * src/tables.c (state_number_to_vector_number,
12774 symbol_number_to_vector_number): Likewise.
12776 * src/gram.h (int_of_rule_number): Remove; no longer used.
12778 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
12779 since the resulting storage is always stored into.
12781 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
12784 * src/muscle_tab.c (muscle_m4_output):
12785 Now inline. Return bool, not int.
12786 * src/state.c (state_compare): Likewise.
12787 * src/symtab.c (symbol_check_defined,
12788 symbol_check_alias_consistency, symbol_pack, symbol_translation,
12789 hash_compare_symbol, hash_symbol):

12796 symbol_check_alias_consistency_processor, symbol_pack_processor,
12797 symbol_translation_processor, hash_symbol_comparator,
12798 hash_symbol_hasher): Likewise.
12799 * src/uniqstr.c (uniqstr_print_processor): Likewise.
12800 * src/muscle_tab.c (muscles_m4_output):
12801 Use new functions instead of casting old functions unportably.
12802 * src/state.c (state_hash_new): Likewise.
12803 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
12804 symbols_token_translations_init):
12806 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
12808 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
12809 var instead of casting to long, to avoid casts.
12810 (prepare_states): Use MALLOC rather than alloca, so that we don't
12811 have to worry about alloca.
12812 * src/state.c (state_hash_lookup): Likewise.
12814 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
12815 local var instead of casting to unsigned char, to avoid casts.
12817 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
12818 STATE_ALLOC): Remove.
12819 (transitions_new, errs_new, reductions_new, state_new): Use malloc
12820 rather than calloc, and use offsetof to avoid allocating slightly
12822 (state_new): Initialize all members.
12824 * src/state.c (state_hash): Use unsigned accumulator, not signed.
12826 * src/symtab.c (symbol_free): Remove; unused.

12829 hashing-related ones.
12831 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
12832 (symbol_processor): Remove.
12833 (symbols_do): Remove decl; now static.
12835 * src/system.h (alloca): Remove; decl no longer needed.
12836 (<stddef.h>): Include, for offsetof.
12837 (<inttypes.>, <stdint.h>): Include if available.
12838 (uintptr_t): New type, if system lacks it.
12839 (CALLOC, MALLOC, REALLOC): New macros.

12858 Change identifier spellings to avoid collisions with names
12859 that are reserved by POSIX.
12861 Don't use names ending in _t, since POSIX reserves them.
12862 For consistency, remove _e and _s endings -- they're weren't
12863 needed to remove ambiguity. All uses changed.
12864 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
12865 turn was just renamed from struniq_t.
12866 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
12867 which in turn was just renamed from struniq_processor_t.
12868 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which

12954 (TAB_EXT): Renamed from EXT_TAB.

12960 * src/uniqstr.c: Renamed from src/struniq.c.

12999 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
13002 Sort include-file uses.
13004 Reorder all include files under src to be in the order "system.h".
13005 then the ../lib include files in angle brackets (alphabetized),
13006 then the . include files in double-quotes (alphabetized). Fix
13007 dependency breakages encountered in this process, as follows:
13008 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
13009 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
13010 * src/state.h: Include "symtab.h".
13012 2002-12-08 Paul Eggert <eggert@twinsun.com>
13014 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
13015 since this causes problems when __file__ contains character
13016 sequences like "@" that are treated specially by src/scan-skel.l.
13017 Instead, just use the file's basename. This fixes the bug
13018 reported by Martin Mokrejs in
13019 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
13021 2002-12-06 Paul Eggert <eggert@twinsun.com>
13023 Add support for rules that do not have trailing semicolons, as
13024 POSIX requires. Improve the quality of locations in Bison
13027 * src/location.c: Include <quotearg.h>.
13028 (empty_location): Now const.
13029 (location_print): New function. Follow the recommendation of the
13030 GNU Coding Standards for locations that span file boundaries.
13031 * src/location.h: Do not include <quotearg.h>; no longer needed.
13032 (boundary): New type.
13033 (location_t): Use it. This allows locations to span file boundaries.
13034 All member uses changed: file -> start.file or end.file (as needed),
13035 first_line -> start.line, first_column -> start.column,
13036 last_line -> end.line, last_column -> end.column.
13037 (equal_boundaries): New function.
13038 (LOCATION_RESET, LOCATION_STEP): Remove.
13039 (LOCATION_PRINT): Remove. All callers changed to use location_print.
13040 (empty_location): Now const.
13041 (location_print): New decl.
13042 * src/parse-gram.y (lloc_default): New function, which handles
13043 empty locations more accurately.
13044 (YYLLOC_DEFAULT): Use it.
13045 (%token COLON): Remove.
13046 (%token ID_COLON): New token.
13048 (declarations, rules): Remove trailing semicolon.
13049 (declaration, rules_or_grammar_declaration):
13050 Allow empty (";") declaration.
13051 (symbol_def): Remove empty actions; no longer needed.
13052 (rules_or_grammar_declaration): Remove trailing semicolon.
13053 (semi_colon.opt): Remove.
13054 * src/reader.h: Include location.h.
13055 (scanner_cursor): New decl.
13056 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
13058 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
13060 (STEP): Remove. No longer needed, now that adjust_location does
13061 the work. All uses removed.
13062 (scanner_cursor): New var.
13063 (adjust_location): Renamed from extend_location. It now sets
13064 *loc and adjusts the scanner cursor. All uses changed.
13065 Don't bother testing for CR.
13066 (handle_syncline): Remove location arg; now updates scanner cursor.
13067 All callers changed.
13068 (unexpected_end_of_file): Now accepts start boundary of token or
13069 comment, not location. All callers changed. Update scanner cursor,
13071 (SC_AFTER_IDENTIFIER): New state.
13072 (context_state): Renamed from c_context. All uses changed.
13073 (id_loc, code_start, token_start): New local vars.
13074 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
13075 processing of Yacc white space and equivalents here.
13076 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
13077 instead of returning ID immediately, since we need to search for
13078 a subsequent colon.
13079 (<INITIAL>"'", "\""): Save token_start.
13080 (<INITIAL>"%{", "{", "%%"): Save code_start.
13081 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
13082 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
13083 BEGIN context_state at end, not INITIAL.
13084 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
13085 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
13086 Return correct token start.
13087 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
13088 the start of a character, string or multiline comment is found.
13089 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
13090 Reduction): Adjust reported locations to match the more-precise
13091 results now expected.
13092 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
13093 * tests/reduce.at (Useless Rules, Reduced Automaton,
13094 Underivable Rules): Likewise.
13095 * tests/regression.at (Invalid inputs): No longer `expecting ";"
13096 or "|"' now that so many other tokens are allowed by the new grammar.
13098 * src/complain.h (current_file): Remove duplicate decl;
13099 current_file is now owned by files.h.
13100 * src/complain.c, src/scan-gram.l: Include files.h.
13102 2002-12-06 Paul Eggert <eggert@twinsun.com>
13104 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
13105 promotes to int; it might be unsigned int.
13106 * data/yacc.c (yy_reduce_print): Likewise.
13108 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
13109 be #defined in the prologue, not in the Bison declarations.
13110 This fixes Debian Bug 102878, reported by Shaul Karl.
13112 2002-12-02 Paul Eggert <eggert@twinsun.com>
13114 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
13115 * lib/strtoul.c: New file, from gnulib.
13116 This fixes a porting bug reported by Peter Klein in
13117 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
13119 2002-11-30 Paul Eggert <eggert@twinsun.com>
13121 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
13122 and put only a forward declaration in the prologue. This is for
13123 consistency with the other scanner helper functions.
13125 Type clashes now generate warnings, not errors, since it
13126 appears that POSIX may allow some grammars with type clashes.
13127 * src/reader.c (grammar_current_rule_check): Warn about
13128 type clashes instead of complaining.
13129 * tests/input.at (Type Clashes): Expect warnings, not complaints.
13131 Add Yacc library, since POSIX requires it.
13132 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
13133 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
13134 * lib/main.c, lib/yyerror.c: New files.
13136 gram_error can be static; it need not be extern.
13137 * src/reader.h (gram_error): Remove decl.
13138 * src/parse-gram.y (gram_error): Now static. Add static decl.
13139 (print_token_value): Omit parameter names from forward decl,
13142 2002-11-29 Paul Eggert <eggert@twinsun.com>
13144 * doc/bison.texinfo: Emphasize that yylex and yyerror must
13145 be declared before being used. E.g., one should typically
13146 declare them in the prologue. Use GNU coding style in examples.
13147 Put "const" consistently after the type it modifies. Mention
13148 that C99 supports "inline". Mention that yyerror traditionally
13151 %parse-param and %lex-param now take just one argument, the
13152 declaration; the argument name is deduced from the declaration.
13154 * doc/bison.texinfo (Parser Function, Pure Calling, Error
13155 Reporting, Table of Symbols): Document this.
13156 * src/parse-gram.y (add_param): New function.
13158 (declaration): Implement new rule for %parse-param and %lex-param.
13159 * src/scan-gram.l: "," now elicits a warning, rather than being
13160 a token; this is more compatible with byacc.
13161 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
13163 2002-11-27 Paul Eggert <eggert@twinsun.com>
13165 Rename identifiers to avoid real and potential collisions.
13167 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
13168 to avoid collision with lex macro described by Bruce Lilly in
13169 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
13170 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
13171 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
13172 * src/parse-gram.y (print_token_value): Renamed from yyprint.
13174 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
13175 The name "yycontrol" violates the name space rules, and this stuff
13176 wasn't being used anyway.
13177 (input): Remove action; this stuff wasn't being used.
13178 (gram_error): Rename local variable yylloc -> loc.
13179 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
13180 (YY_DECL): Don't use "yy" at start of local variables.
13181 All uses changed, e.g., yylloc -> loc.
13182 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
13183 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
13184 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
13185 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
13187 * src/parse-gram.y (gram_error): loc is now const *.
13188 * src/reader.h (gram_error): Likewise.
13190 2002-11-24 Paul Eggert <eggert@twinsun.com>
13194 * tests/actions.at (Actions after errors): Use an output format
13195 more similar to that of the Printers and Destructors test.
13196 Test the position of the ';' token too.
13197 (Printers and Destructors): Likewise.
13198 (Printers and Destructors: %glr-parser): Remove for now, to avoid
13199 unnecessarily alarming people when the test fails.
13201 * data/yacc.c (yyerrlab1): Move this label down, so that the
13202 parser does not discard the lookahead token if the user code
13203 invokes YYERROR. This change is required for POSIX conformance.
13205 * lib/error.c: Sync with gnulib.
13207 2002-11-22 Paul Eggert <eggert@twinsun.com>
13209 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
13210 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
13211 * lib/xmalloc.c: Likewise.
13213 2002-11-20 Paul Eggert <eggert@twinsun.com>
13215 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
13217 2002-11-20 Paul Eggert <eggert@twinsun.com>
13219 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
13220 should use `if (! x) abort ();' rather than `assert (x);', and
13221 anyway it's one less thing to worry about configuring.
13223 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
13224 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
13225 and replace all instances of assert with abort.
13226 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
13227 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
13229 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
13230 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
13231 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
13232 hash_find_entry, hash_rehash, hash_insert): Likewise.
13233 * src/conflicts.c (resolve_sr_conflict): Likewise.
13234 * src/lalr.c (set_goto_map, map_goto): Likewise.
13235 * src/nullable.c (nullable_compute): Likewise.
13236 * src/output.c (prepare_rules, token_definitions_output): Likewise.
13237 * src/reader.c (packgram, reader): Likewise.
13238 * src/state.c (state_new, state_free, state_transitions_set,
13239 state_reduction_find): Likewise.
13240 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
13241 symbol_pack): Likewise.
13242 * src/tables.c (conflict_row, pack_vector): Likewise.
13243 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
13244 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
13245 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
13246 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
13248 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
13249 (ARGMATCH_CONSTRAINT): New macro.
13250 (ARGMATCH_ASSERT): Use it.
13252 * src/system.h (verify): New macro.
13253 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
13254 rather than assert.
13255 * src/tables.c (tables_generate): Likewise.
13257 * src/struniq.c (struniq_assert): Now returns void, and aborts
13258 if the assertion is false.
13259 (struniq_assert_p): Remove.
13260 * src/struniq.h: Likewise.
13262 2002-11-18 Paul Eggert <eggert@twinsun.com>
13264 * data/glr.c (yygetLRActions): Replace `yyindex' with
13265 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
13266 This fixes the regression with Sun ONE Studio 7 cc that I reported in
13267 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
13269 2002-11-18 Akim Demaille <akim@epita.fr>
13271 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
13273 From Tim Van Holder.
13275 2002-11-17 Paul Eggert <eggert@twinsun.com>
13277 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
13278 to "SyntaxError" for consistency with my 2002-11-15 change.
13280 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
13281 not define to {}, since this breaks the common use of `YYDPRINTF
13282 ((...));' if a single statement is desired (e.g. before `else').
13283 Work around GCC warnings by surrounding corresponding calls with
13285 (yyhasResolvedValue): Remove unused function.
13286 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
13288 (yyreportSyntaxError): Renamed from yyreportParseError.
13289 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
13291 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
13292 extern when possible. Remove unused initializations.
13294 2002-11-16 Akim Demaille <akim@epita.fr>
13296 Augment the similarity between GLR and LALR traces.
13298 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
13299 (YY_REDUCE_PRINT): New.
13300 (yyparse): Use them.
13301 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
13303 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
13304 state reached after the reduction/recovery, since...
13305 (yyparse, yyprocessOneStack): Report the state we are entering in.
13307 2002-11-16 Akim Demaille <akim@epita.fr>
13309 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
13310 Add support for --trace=skeleton.
13311 * src/scan-skel.l: %option debug.
13312 Scan strings of non-@ or \n instead of character by character.
13313 (scan_skel): Handle trace_skeleton.
13315 (@output_parser_name@, @output_header_name@): ``Restore'' their
13316 support (used to be M4 macros).
13317 * data/yacc.c: Quote larger chunks, a la glr.c.
13318 * data/lalr1.cc: Likewise.
13319 The header guards are no longer available, so use some other
13320 string than `YYLSP_NEEDED'.
13322 2002-11-16 Akim Demaille <akim@epita.fr>
13324 Make the ``Printers and Destructors'' test more verbose, taking
13325 `yacc.c''s behavior as (possibly wrong) reference.
13327 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
13328 instead of fprint on stdout.
13329 Set and report the last_line of the symbols.
13330 Consistently display values and locations.
13332 2002-11-16 Paul Eggert <eggert@twinsun.com>
13334 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
13336 2002-11-15 Paul Eggert <eggert@twinsun.com>
13338 * tests/actions.at (Actions after errors): New test case.
13340 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
13341 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
13342 tests/action.at, tests/calc.at, tests/conflicts.at,
13343 tests/cxx-type.at, tests/regression.at:
13344 "parse error" -> "syntax error" for POSIX compatibility.
13345 "parsing stack overflow..." -> "parser stack overflow" so
13346 that code matches Bison documentation.
13348 2002-11-15 Akim Demaille <akim@epita.fr>
13350 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
13351 take two BRACED_CODE, not two string_content.
13352 Free the scanner's obstack when we are done.
13353 (code_content): New.
13354 * tests/calc.at: Adjust.
13355 * doc/bison.texinfo: Adjust.
13356 Also, make sure to include the `,' for these declarations.
13358 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
13360 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
13361 definition; avoids potential autoreconf problems.
13363 2002-11-15 Akim Demaille <akim@epita.fr>
13365 Always check the value returned by yyparse.
13367 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
13368 returned by yyparse.
13369 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
13371 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
13372 returned by yyparse.
13374 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
13376 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
13379 2002-11-14 Paul Eggert <eggert@twinsun.com>
13381 * src/output.c (output_skeleton): Call xfopen instead of
13382 duplicating xfopen's body.
13384 Fix bugs reported by Nelson H. F. Beebe in
13385 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
13387 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
13388 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
13389 Group compiler. Instead, use "$CC -E bar.c". Include the .h
13390 file twice in the grammar, as an extra check.
13392 * tests/input.at (Torturing the Scanner): Surround the
13393 backslash-newline tests with "#if 0", to make it less likely that
13394 we'll run into compiler bugs. Bring back solitary \ inside
13395 comment, but add a closing comment to work around HP C bug. Don't
13396 test backslash-newline in C character constant.
13398 2002-11-14 Akim Demaille <akim@epita.fr>
13400 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
13401 status of the compiler.
13402 Calling `exit 1' is no longer needed.
13403 Reported by Nelson H. F. Beebe.
13405 2002-11-14 Akim Demaille <akim@epita.fr>
13407 * tests/atlocal.in (CPPFLAGS): We have config.h.
13408 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
13410 * tests/actions.at, tests/calc.at, tests/conflicts.at,
13411 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
13412 * tests/regression.at, tests/torture.at: Use them for all the
13413 grammars that are to be compiled.
13414 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
13415 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
13416 * doc/bison.texinfo (GLR Parsers): Document `inline'.
13418 2002-11-14 Akim Demaille <akim@epita.fr>
13420 * doc/bison.texinfo: Various formatting changes (alignments in
13421 samples, additional @group/@end group, GCS in samples.
13422 Use @deffn instead of simple @table to define the directives,
13423 macros, variables etc.
13425 2002-11-13 Paul Eggert <eggert@twinsun.com>
13427 Fix some bugs reported by Albert Chin-A-Young in
13428 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
13430 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
13431 -o c"; the HP C compiler chatters during compilation.
13432 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
13433 * tests/headers.at (export YYLTYPE): Likewise.
13435 * tests/input.at (Torturing the Scanner): Remove lines containing
13436 solitary backslashes, as they tickle a bug in the HP C compiler.
13438 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
13439 comments, since they're not portable. Use GNU coding style.
13441 2002-11-13 Akim Demaille <akim@epita.fr>

13461 (bitset_set, bitset_reset, bitset_test): Rename local vars
13462 to avoid shadowing warnings by GCC.
13464 * data/glr.c (inline): Remove #define. It's the user's
13465 responsibility to #define it away, just like 'const'.
13466 This fixes one of the bugs reported by Nelson H. F. Beebe in
13467 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
13469 * Makefile.maint (po-check): Scan .l and .y files instead of the
13470 .c and the .h files that they generate. This fixes the bug
13471 reported by Tim Van Holder in:
13472 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
13473 Look for N_ as well as for _. Try to avoid matching #define for

13478 do not confuse xgettext.
13480 * src/struniq.h (struniq_new): Do not declare the return type
13481 to be 'const'; this violates the C standard.
13482 * src/struniq.c (struniq_new): Likewise.
13484 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
13486 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the

13536 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
13537 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
13538 it against YYEMPTY and so forth), work on yytoken (i.e., set
13539 it to YYEMPTY etc.).
13540 (yydestruct): Replace with a b4_yydestruct_generate invocation.
13541 (b4_symbol_actions): Remove.
13542 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands

13628 2002-11-11 Paul Eggert <eggert@twinsun.com>
13630 Revamp to fix many (but not all) of the C- and M4-related quoting
13631 problems. Among other things, this fixes the Bison bug reported
13632 by Jan Hubicka when processing the Bash grammar; see:
13633 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
13635 Use new @ escapes consistently. Represent brackets with @{ and @}
13636 rather than @<:@ and @:>@, since this works a bit better with dumb
13637 editors like vi. Represent @ with @@, since @ is now consistently
13638 an escape. Use @oline@ and @ofile@ rather than __oline__ and
13639 __ofile__, to avoid unexpected expansions. Similarly, use @output
13640 rather than #output.
13642 * data/c.m4 (b4_copyright): Omit file name from comment, since
13643 the file name could contain "*/".
13644 (b4_synclines_flag): Don't quote the 2nd argument; it should already
13645 be quoted. All uses changed.
13647 * data/glr.c: Use new @ escapes consistently.
13648 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
13649 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
13650 Remove, since they couldn't handle arbitrary characters in file
13652 * data/lalr1.cc: Likewise.
13653 * data/yacc.c: Likewise.
13655 * src/files.c (output_infix): Remove; all uses removed.
13656 * src/files.h: Likewise.
13658 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
13659 mishandled funny characters in file names, and anyway it isn't
13661 * data/yacc.c: Likewise.
13662 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
13664 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
13665 * data/yacc.c: Likewise.
13667 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
13669 (muscle_init): Quote filename as a C string.
13670 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
13671 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
13672 * src/output.c (escaped_file_name_output): New function.
13673 (prepare_symbols): Quote tokens for M4.
13674 (prepare): Don't insert output_infix, output_prefix,
13675 output_parser_name, output_header_name; this is now down by scan-skel.
13676 Insert skeleton as a C string.
13678 * src/output.c (user_actions_output, symbol_destructors_output,
13679 symbol_printers_output): Quote filenames for C and M4.
13680 * src/reader.c (prologue_augment, epilogue_set): Likewise.
13682 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
13683 escapes other than \\ and \'; this simplifies the code.
13684 (<SC_STRING>): Likewise, for \\ and \".
13685 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
13686 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
13687 Use new escapes @{ and @} for [ and ].
13689 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
13690 them with auto vars.
13691 Switch to new escape scheme, where @ is the escape character uniformly.
13692 Abort if a stray escape character is found. Avoid unbounded input
13693 buffer when parsing non-escaped text.
13695 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
13696 __oline__, #output, $@, and @{ do not have unintended meanings.
13698 2002-11-09 Paul Eggert <eggert@twinsun.com>
13700 Fix the test failure due to GCC warnings described in
13701 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
13702 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
13703 evaluate to 0 if it's impossible for NINF to be in the respective
13705 (yygetLRActions, yyrecoverParseError): Use them.
13707 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
13708 counted in the token inserted at end of file. Now takes
13709 location_t *, not location_t, so that the location can be
13710 adjusted. All uses changed.
13712 * tests/regression.at (Invalid inputs): Adjust wording in
13713 diagnostic to match the new behavior.
13715 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
13716 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
13717 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
13718 abort ();'. This reduces the runtime of the "Many lookaheads"
13719 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
13722 2002-11-07 Paul Eggert <eggert@twinsun.com>
13724 * src/parse-gram.y (CHARACTER): Remove unused token.
13727 * src/scan-gram.l: Remove stack option. We no longer use the
13728 stack, since the stack was never deeper than 1; instead, use the
13729 new auto var c_context to record the stacked value.
13731 Remove nounput option. At an unexpected end of file, we now unput
13732 the minimal input necessary to end cleanly; this simplifies the
13735 Avoid unbounded token sizes where this is easy.
13737 (unexpected_end_of_file): New function.
13738 Use it to systematize the error message on unexpected EOF.
13739 (last-string): Now auto, not static.
13740 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
13741 (scanner_last_string_free): Remove; not used.
13742 (percent_percent_count): Move decl to just before use.
13743 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
13744 not the (never otherwised-used) CHARACTER.
13746 2002-11-07 Akim Demaille <akim@epita.fr>

13909 (YY_INPUT): New macro.
13910 (no_cr_read): New function.
13912 Scan UCNs, even though we don't fully handle them yet.
13913 (convert_ucn_to_byte): New function.
13915 Handle backslash-newline correctly in C code.
13916 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
13917 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
13919 (tag, splice): New EREs. Do not allow NUL or newline in tags.
13920 Use {splice} wherever C allows backslash-newline.
13921 YY_STEP after space, newline, vertical-tab.
13922 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
13924 (letter, id): Don't assume ASCII; e.g., spell out a-z.
13926 ({int}, handle_action_dollar, handle_action_at): Check for integer
13929 (YY_STEP): Omit trailing semicolon, so that it's more like C.
13931 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
13932 as well as \000. Check for UCHAR_MAX, not 255.
13933 Allow \x with an arbitrary positive number of digits, as in C.
13934 Check for overflow here.
13935 Allow \? and UCNs, for compatibility with C.
13937 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
13938 with quote slot used by complain_at.
13940 * tests/input.at: Add tests for backslash-newline, m4 quotes
13941 in symbols, long literals, and funny escapes in strings.
13943 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
13944 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
13945 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
13946 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
13947 * m4/mbswidth.m4: New file, from GNU coreutils.
13949 * doc/bison.texinfo (Grammar Outline): Document // comments.
13950 (Symbols): Document that trigraphs have no special meaning in Bison,
13951 nor is backslash-newline allowed.
13952 (Actions): Document that trigraphs have no special meaning.
13954 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
13957 2002-11-02 Paul Eggert <eggert@twinsun.com>
13959 * src/reader.c: Don't include quote.h; not needed.
13960 (get_merge_function): Reword warning to be consistent with
13961 type clash diagnostic in grammar_current_rule_check.
13963 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
13964 bug in trigraph handling.
13966 * src/output.c (prepare_symbols): When printing token names,
13967 escape "[" as "@<:@" and likewise for "]".
13969 * src/system.h (errno): Remove declaration, as we are now
13970 assuming C89 or better, and C89 guarantees errno.
13972 2002-10-30 Paul Eggert <eggert@twinsun.com>
13974 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
13975 Check for close failures.
13976 * src/files.h (xfclose): Return void, not int, since it always
13978 * src/files.c (xfclose): Likewise. Report I/O error if ferror
13980 * src/output.c (output_skeleton): Use xfclose rather than fclose
13981 and ferror. xfclose now checks ferror.
13983 * data/glr.c (YYLEFTMOST_STATE): Remove.
13984 (yyreportTree): Use a stack-based leftmost state. This avoids
13985 our continuing battles with bogus warnings about initializers.
13987 2002-10-30 Akim Demaille <akim@epita.fr>
13989 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
13992 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
13994 * tests/glr-regr1.at: New test for reported regressions.
13995 * tests/testsuite.at: Add glr-regr1.at test.
13996 * tests/Makefile.am: Add glr-regr1.at test.
13998 2002-10-24 Paul Eggert <eggert@twinsun.com>
14002 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
14003 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
14004 we use malloc. Don't assume 'A' through 'Z' are contiguous.
14005 Don't assume strdup exists; POSIX says its an XSI extension.
14006 Check for buffer overflow on input.
14008 2002-10-24 Akim Demaille <akim@epita.fr>
14010 * src/output.c (output_skeleton): Don't disable M4sugar comments
14011 too soon: it results in comments being expanded.
14012 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
14015 2002-10-24 Akim Demaille <akim@epita.fr>
14017 * data/yacc.c (m4_int_type): New.
14018 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
14019 char' as only yacc.c wants K&R portability.
14020 * data/glr.c (yysigned_char): Remove.
14021 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
14022 Reported by Quoc Peyrot.
14024 2002-10-23 Paul Eggert <eggert@twinsun.com>
14026 * src/main.c (main): With --trace=time, report times even if a
14027 non-fatal error occurs. Formerly, the times were reported in some
14028 such cases but not in others.
14029 * src/reader.c (reader): Just return if a complaint has been issued,
14030 instead of exiting, so that 'main' can report times.
14032 2002-10-22 Akim Demaille <akim@epita.fr>
14034 * src/system.h: Include sys/types.
14035 Reported by Bert Deknuydt.
14037 2002-10-23 Paul Eggert <eggert@twinsun.com>
14039 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
14040 Suggested by Art Haas.
14042 2002-10-22 Paul Eggert <eggert@twinsun.com>
14044 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
14045 decl; not needed any more.
14046 * src/main.c (main): Use return to exit, undoing yesterday's change.
14047 The last OS that we could find where this wouldn't work is
14048 SunOS 3.5, and that's too old to worry about now.
14050 * data/glr.c (struct yyltype): Define members even when not
14051 doing locations. This is more consistent with yacc.c, and it
14052 works around the following bug reports:
14053 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
14054 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
14056 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
14057 @acronym consistently. Standardize on "Yacc" instead of "YACC",
14058 "Algol" instead of "ALGOL". Give a bit more history about BNF.
14060 2002-10-22 Akim Demaille <akim@epita.fr>
14062 * data/README: New.
14064 2002-10-21 Paul Eggert <eggert@twinsun.com>
14066 Be consistent about 'bool'; the old code used an enum in one
14067 module and an int in another, and this violates the C standard.
14068 * m4/stdbool.m4: New file, from coreutils 4.5.3.
14069 * configure.ac (AC_HEADER_STDBOOL): Add.
14070 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
14071 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
14072 * src/symtab.c (hash_compare_symbol_t): Likewise.
14073 * src/system.h (bool, false, true): Use a definition consistent
14074 with ../lib/hash.c. All uses changed.
14076 * src/complain.c (warning_issued): Renamed from warn_message_count,
14077 so that we needn't worry about integer overflow (!).
14078 Now of type bool. All uses changed.
14079 (complaint_issued): Renamed from complain_message_count; likewise.
14081 * src/main.c (main): Use exit to exit with failure.
14083 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
14084 rather than 1 and 0.
14085 * src/main.c (main): Likewise.
14086 * src/getargs.c (getargs): Likewise.
14087 * src/reader.c (reader): Likewise.
14089 * src/getarg.c (getargs): Remove duplicate code for
14090 "Try `bison --help'".
14092 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
14093 What was that "2" for?
14095 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
14096 * src/getargs.c (usage): Likewise.
14098 * src/getargs.c (getargs): When there are too few operands, report
14099 the last one. When there are too many, report the first extra
14100 one. This is how diffutils does it.
14102 2002-10-20 Paul Eggert <eggert@twinsun.com>
14104 Remove K&R vestiges.
14105 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
14106 * src/complain.c (VA_START): Remove. Assume prototypes.
14107 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
14108 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
14109 fatal): Assume prototypes.
14110 * src/complain.h: Assume prototypes.
14111 * src/system.h (PARAMS): Remove.
14112 Include <limits.h> unconditionally, since it's guaranteeed even
14113 for a freestanding C89 compiler.
14114 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
14115 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
14117 2002-10-20 Akim Demaille <akim@epita.fr>
14119 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
14120 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
14121 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
14122 (yyresolveStates, yyresolveAction, yyresolveStack)
14123 (yyprocessOneStack): Use them.
14124 (yy_reduce_print): New.
14125 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
14127 2002-10-20 Akim Demaille <akim@epita.fr>
14129 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
14130 arguments and output `void'.
14131 (b4_c_function): Rename as...
14132 (b4_c_function_def): this.
14133 (b4_c_function_decl, b4_c_ansi_function_def)
14134 (b4_c_ansi_function_decl): New.
14135 Change the interpretation of the arguments: before `int, foo', now
14137 * data/yacc.c (yyparse): Prototype and define thanks to these.
14138 Adjust b4_c_function_def uses.
14139 * data/glr.c (yyparse): Likewise, but ANSI only.
14141 2002-10-20 Akim Demaille <akim@epita.fr>
14143 * src/output.c (prepare): Move the definition of `tokens_number',
14144 `nterms_number', `undef_token_number', `user_token_number_max'
14146 (prepare_tokens): Here.
14147 (prepare_tokens): Rename as...
14148 (prepare_symbols): this.
14149 (prepare): Move the definition of `rules_number' to...
14150 (prepare_rules): here.
14151 (prepare): Move the definition of `last', `final_state_number',
14152 `states_number' to...
14153 (prepare_states): here.
14154 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
14156 2002-10-20 Akim Demaille <akim@epita.fr>
14158 * src/tables.h, src/tables.c, src/output.c: Comment changes.
14160 2002-10-20 Akim Demaille <akim@epita.fr>
14162 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
14165 2002-10-20 Akim Demaille <akim@epita.fr>
14167 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
14168 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
14170 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
14172 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
14173 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
14176 2002-10-19 Paul Eggert <eggert@twinsun.com>
14178 Do not create a temporary file, as that involves security and
14179 cleanup headaches. Instead, use a pair of pipes.
14180 Derived from a suggestion by Florian Krohm.
14181 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
14182 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
14183 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
14184 (BISON_PREREQ_SUBPIPE): Add.
14185 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
14186 Add subpipe.h, subpipe.c.
14187 * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4.
14188 * po/POTFILES.in: Add lib/subpipe.c.

14190 (m4_invoke): Remove decl.
14191 (scan_skel): New decl.
14192 (output_skeleton): Use pipe rather than temporary file for m4 input.
14193 Check that m4sugar.m4 is readable, to avoid deadlock.
14194 Check for pipe I/O error.
14195 * src/scan-skel.l (readpipe): Remove decl.
14196 (scan_skel): New function, to be used in place of m4_invoke.
14197 Read from stream rather than file.
14199 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
14200 float, as this generates a warning on Solaris 8 + GCC 3.2 with
14201 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
14202 this generates a more-accurate value anyway.
14204 * lib/timevar.c (timervar_accumulate): Rename locals to
14205 avoid confusion with similarly-named more-global.
14206 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
14208 * src/output.c (prepare): Use xstrdup to convert char const *
14209 to char *, to avoid GCC warning.
14211 2002-10-19 Akim Demaille <akim@epita.fr>
14213 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
14214 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
14215 Use them to have `calc.y' ready for %pure-parser.
14216 * data/yacc.c (YYLEX): Pass a yylex return type to
14217 b4_c_function_call.
14219 2002-10-19 Akim Demaille <akim@epita.fr>
14221 Prototype support of %lex-param and %parse-param.
14223 * src/parse-gram.y: Add the definition of the %lex-param and
14224 %parse-param tokens, plus their rules.
14225 Drop the `_' version of %glr-parser.
14227 * src/scan-gram.l (INITIAL): Scan them.
14228 * src/muscle_tab.c: Comment changes.

14231 (muscle_entry_s): The `value' member is no longer const.
14232 Adjust all dependencies.
14233 * src/muscle_tab.c (muscle_init): Adjust: use
14234 MUSCLE_INSERT_STRING.
14235 Initialize the obstack earlier.
14236 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
14237 (muscle_pair_list_grow): New.
14238 * data/c.m4 (b4_c_function_call, b4_c_args): New.
14239 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
14240 * tests/calc.at: Use %locations, not --locations.
14241 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
14243 2002-10-19 Akim Demaille <akim@epita.fr>
14245 * src/getargs.c (usage): Take status as argument and exit
14247 Report the traditional `Try ... --help' message when status != 0.
14248 (usage, version): Don't take a FILE * as arg, it is pointless.
14249 (getargs): When there is an incorrect number of arguments, make it
14250 an error, and report it GNUlically thanks to `usage ()'.
14252 2002-10-18 Paul Eggert <eggert@twinsun.com>
14254 * data/glr.c (yyreportParseError): Don't assume that sprintf
14255 yields the length of the printed string, as this is not true
14256 on SunOS 4.1.4. Reported by Peter Klein.
14258 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
14259 * tests/conflicts.at (%nonassoc and eof): Likewise.
14260 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
14262 2002-10-17 Akim Demaille <akim@epita.fr>
14264 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
14265 * src/getargs.c (trace_types, trace_args): Adjust.
14266 * src/reader.c (grammar_current_rule_prec_set)
14267 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
14268 Standardize error messages.
14269 And s/@prec/%prec/!
14270 (reader): Use trace_flag to enable scanner/parser debugging,
14271 instead of an adhoc scheme.
14272 * src/scan-gram.l: Remove trailing debugging code.
14274 2002-10-16 Paul Eggert <eggert@twinsun.com>
14276 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
14279 * NEWS: Officially drop support for building Bison with K&R C,
14280 since it didn't work anyway and it's not worth worrying about.
14281 * Makefile.maint (wget_files): Remove ansi2knr.c.
14282 (ansi2knr.c-url_prefix): Remove.
14283 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
14284 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
14285 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
14287 2002-10-15 Paul Eggert <eggert@twinsun.com>
14289 Stop using the "enum_" trick for K&R-style function definitions;
14290 it confused me, and I was the author! Instead, assume that people
14291 who want to use K&R C compilers (when using these modules in GCC,
14292 perhaps?) will run ansi2knr.
14294 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
14295 All uses of "enum_" changed to "enum ".
14296 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
14297 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
14299 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

14306 abitset_size, abitset_small_list, abitset_subset_p, abitset_test,
14307 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
14308 Use function prototypes; this removes the need for declaring
14309 static functions simply to provide their prototypes.
14310 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,
14311 bitset_andn_or_, bitset_andn_or_cmp_, bitset_bytes, bitset_copy_,

14320 * lib/bitset_stats.c (bitset_log_histogram_print,
14321 bitset_percent_histogram_print, bitset_stats_and,

14384 tests/cxx-type.at, tests/headers.at, tests/input.at,

14386 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
14387 so that the tests still work even if POSIXLY_CORRECT is set.
14388 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
14390 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
14391 for portability to K&R hosts. Fix typo: signed char is guaranteed
14392 only to 127, not to 128.
14393 * data/glr.c (yysigned_char): New type.

14397 2002-10-13 Paul Eggert <eggert@twinsun.com>
14399 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
14400 true due to limited range of data type" warning from GCC.
14402 * data/c.m4 (b4_token_defines): Protect against double-inclusion
14403 by wrapping enum yytokentype's definition inside #ifndef
14404 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
14406 2002-10-13 Akim Demaille <akim@epita.fr>
14408 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):

14424 Let nondeterministic skeletons be usable with deterministic
14427 With the patch, GAWK compiled by GCC without -O2 passes its test
14428 suite using a GLR parser driven by LALR tables. It fails with -O2
14429 because `struct stat' gives two different answers on my machine:
14430 88 (definition of an auto var) and later 96 (memset on this var).
14431 Hence the stack is badly corrumpted. The headers inclusion is to
14432 blame: if I move the awk.h inclusion before GLR's system header
14433 inclusion, the two struct stat have the same size.
14435 * src/tables.c (pack_table): Always create conflict_table.
14436 (token_actions): Always create conflict_list.
14437 * data/glr.c (YYFLAG): Remove, unused.

14441 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.

14455 2002-10-13 Akim Demaille <akim@epita.fr>
14457 GLR parsers sometimes raise parse errors instead of performing the
14459 Reported by Charles-Henry de Boysson.
14461 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
14462 check the length of the traces when %glr.
14463 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
14465 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
14467 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
14468 (yyltype): Remove the yy prefix from the member names.
14469 (yytable): Complete its comment.
14470 (yygetLRActions): Map error action number from YYTABLE from
14472 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
14473 (which was a bug: it should have been YYTABEL_NINF, and yet it was
14474 not satisfying as we could compare an YYACTION computed from
14475 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
14476 only value for error actions.
14477 (yyreportParseError): In verbose parse error messages, don't issue
14478 `error' in the list of expected tokens.
14479 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
14480 next action to perform to match glr.c's decoding.

14487 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
14488 because the Bison parser reads the second action before reducing
14490 * src/scan-gram.l (rule_length): New static var.
14491 Use it to keep track of the rule length in the scanner, since
14492 we can't expect the parser to be in lock-step sync with the scanner.
14493 (handle_action_dollar, handle_action_at): Use this var.

14500 Include <sys/time.h> when checking for clock_t and struct tms.
14501 Use same include order as source.
14502 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
14503 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
14505 * lib/timevar.c: Update copyright date and clarify comments.
14506 (get_time) [IN_GCC]: Keep the GCC version for reference.
14508 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
14509 GCC version as of today, then merge Bison's changes.
14510 Change "GCC" to "Bison" in copyright notice. timevar.def's
14511 author is Akim, so change that too.
14513 * src/reader.c (grammar_current_rule_check):
14514 Don't worry about the default action if $$ is untyped.

14550 * lib/abitset.c (abitset_bytes): Return a size that is aligned

14594 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
14596 Do not use "struct bitset_struct" to mean different things in
14597 different modules. Not only is this confusing, it violates
14598 the C Standard, which requires that structure types in different
14599 modules must be compatible if one is to be passed to the other.

14647 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,

14661 signifies end-of-input. Warn about negative chars. Mention
14662 the portable Standard C character set.

14749 BITSET_SIZE_MAX): New macros.
14750 (BITSET_INDEX_MAX): Remove. It wasn't right, since it assumed that
14751 sizeof (bitset_word) == sizeof (bitset_windex). All uses changed
14752 to BITSET_WINDEX_MAX.
14754 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
14755 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,
14756 since we now return the bitset_bindex type (not int).

14854 2002-09-06 Paul Eggert <eggert@twinsun.com>
14856 * doc/bison.texinfo (Conditions): Make explicit that the GPL
14857 exception applies only to yacc.c. This is a modification of a
14858 patch originally suggested by Akim Demaille.
14860 2002-09-06 Akim Demaille <akim@epita.fr>

14872 * data/yacc.c: Guard the declaration of yytoknum also with

14910 as int, and similarly for yyposn and YYINDEX.

14952 PROTOTYPES to check for prototypes, and "defined __STDC__" to

14956 size_t; the old version tried to do this but casted improperly.
14957 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
14958 (bitset_test): Now returns int, not unsigned long.
14960 * lib/bitset_stats.c: Include "gettext.h".
14962 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
14963 name locals "index", as it generates unnecessary warnings on some

15002 to void, to avoid a GCC warning when --disable-nls is in effect.
15004 * src/scan-gram.l: Use strings rather than escapes when possible,
15005 to minimize the number of warnings from xgettext.
15006 (handle_action_dollar, handle_action_at): Don't use isdigit,
15007 as it mishandles negative chars and it may not work as expected
15008 outside the C locale.
15010 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
15011 this is a GCC extension and is not portable to other compilers.

15018 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
15021 * tests/regression.at: Do not use 'cc -c input.c -o input';
15022 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
15024 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
15025 exit status as failure, not just exit status 1. Sun C exits
15026 with status 2 sometimes.
15028 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
15029 Use it for the two large tests.
15031 2002-08-02 Akim Demaille <akim@epita.fr>
15033 * src/conflicts.c (conflicts_output): Don't output rules never
15034 reduced here, since anyway that computation doesn't work.

15045 that rules never reduced are computed.
15046 Call grammar_rules_never_reduced_report.
15047 * src/print.c (print_results): Report rules never reduced.
15048 * tests/conflicts.at, tests/reduce.at: Adjust.
15050 2002-08-01 Akim Demaille <akim@epita.fr>

15075 2002-08-01 Akim Demaille <akim@epita.fr>

15080 (derives_compute, derives_free): this.
15081 Adjust all dependencies.
15082 * src/nullable.c (set_nullable, free_nullable): Rename as...
15083 (nullable_compute, nullable_free): these.
15084 (rule_list_t): Store rule_t *, not rule_number_t.
15085 * src/state.c (state_rule_lookaheads_print): Directly compare rule
15086 pointers, instead of their numbers.
15087 * src/main.c (main): Call nullable_free, and derives_free earlier,
15088 as they were lo longer used.

15172 * tests/calc.at (Calculator $1): Adjust.

15189 Report rules which are never reduced by the parser: those hidden

15193 different: save its reduction (accept) instead of having a state
15194 without any action (no shift or goto, no reduce).
15195 Note: the final state is now a ``regular'' state, i.e., the
15196 parsers now contain `reduce 0' as default reduction.
15197 Nevertheless, since they decide to `accept' when yystate =
15198 final_state, they still will not reduce rule 0.
15199 * src/print.c (print_actions, print_reduction): Adjust.
15200 * src/output.c (action_row): Track reduced rules.
15201 (token_actions): Report rules never reduced.

17145 2002-04-07 Akim Demaille <akim@epita.fr>
17147 As a result of the previous patch, it is no longer needed
17148 to reorder ritem itself.
17150 * src/reduce.c (reduce_grammar_tables): Don't sort RITEM.
17152 2002-04-07 Akim Demaille <akim@epita.fr>
17154 Be sure never to walk through RITEMS, but use only data related to
17155 the rules themselves. RITEMS should be banished.
17157 * src/output.c (output_token_translations): Rename as...
17158 (prepare_tokens): this.
17159 In addition to `translate', prepare the muscles `tname' and
17160 `toknum', which were handled by...
17161 (output_rule_data): this.
17162 Remove, and move the remainder of its outputs into...
17163 (prepare_rules): this new routines, which also merges content from
17164 (output_gram): this.
17165 (prepare_rules): Be sure never to walk through RITEMS.
17166 (output_stos): Rename as...
17167 (prepare_stos): this.
17168 (output): Always invoke prepare_states, after all, just don't use it
17169 in the output if you don't need it.

17173 * src/LR0.c (new_state): Display `nstates' as the name of the
17174 newly created state.
17175 Adjust to initialize first_state and last_state if needed.
17176 Be sure to distinguish the initial from the final state.
17177 (new_states): Create the itemset of the initial state, and use
17179 * src/closure.c (closure): Now that the initial state has its
17180 items properly set, there is no need for a special case when
17181 creating `ruleset'.
17183 As a result, now the rule 0, reducing to $axiom, is visible in the
17184 outputs. Adjust the test suite.
17186 * tests/conflicts.at (Solved SR Conflicts)
17187 (Unresolved SR Conflicts): Adjust.
17188 * tests/regression.at (Web2c Report, Rule Line Numbers): Idem.

17203 `number' of the buckets too.
17204 * src/gram.h: Include `symtab.h'.
17205 (associativity): Move to...
17206 * src/symtab.h: here.
17207 No longer include `gram.h'.
17209 2002-04-07 Akim Demaille <akim@epita.fr>
17211 * src/gram.h, src/gram.c (rules_rhs_length): New.
17212 (ritem_longest_rhs): Use it.

17214 * src/reader.c (packgram): Set it.
17215 * src/reduce.c (reduce_grammar_tables): Move the useless rules at
17216 the end of `rules', and count them out of `nrules'.
17217 (reduce_output, dump_grammar): Adjust.
17218 * src/print.c (print_grammar): It is no longer needed to check for
17219 the usefulness of a rule, as useless rules are beyond `nrules + 1'.
17220 * tests/reduce.at (Reduced Automaton): New test.
17222 2002-04-07 Akim Demaille <akim@epita.fr>
17224 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
17225 lacking `+ 1' to nrules, Bison reported as useless a token if it
17226 was used solely to set the precedence of the last rule...
17228 2002-04-07 Akim Demaille <akim@epita.fr>
17230 * data/bison.c++, data/bison.simple: Don't output the current file
17231 name in #line, to avoid useless diffs between two identical
17232 outputs under different names.
17234 2002-04-07 Akim Demaille <akim@epita.fr>
17236 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:
17237 Normalize loops to using `< nrules + 1', not `<= nrules'.

17251 * src/nullable.c, src/output.c, src/print.c, src/print_graph.c,
17252 * src/reader.c, src/reduce.c: Let rule_t.rhs point directly to the
17253 RHS, instead of being an index in RITEMS.
17255 2002-04-04 Paul Eggert <eggert@twinsun.com>
17257 * doc/bison.texinfo: Update copyright date.
17258 (Rpcalc Lexer, Symbols, Token Decl): Don't assume ASCII.

17263 2002-04-03 Paul Eggert <eggert@twinsun.com>
17265 * src/bison.data (YYSTACK_ALLOC): Depend on whether
17266 YYERROR_VERBOSE is nonzero, not whether it is defined.
17268 Merge changes from bison-1_29-branch.
17270 2002-03-20 Paul Eggert <eggert@twinsun.com>
17272 Merge fixes from Debian bison_1.34-1.diff.

17522 2002-02-14 Paul Eggert <eggert@twinsun.com>
17524 Remove the support for C++ namespace cleanliness; it was

17618 line number, hence remove the second argument.

17622 (output_skeleton): Don't look for the skeleton location, let m4 do
17624 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
17626 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
17627 (prepare): Given that for the time being changesyntax is not
17628 usable in M4, rename the muscles using `-' to `_'.
17629 Define `defines_flag', `output_parser_name' and `output_header_name'.
17630 * src/output.h (actions_output, guards_output)
17631 (token_definitions_output): Adjust prototypes.

17645 * configure.in: Check for the declarations of free and malloc.
17646 * src/muscle_tab.c: Adjust.
17648 2002-02-05 Akim Demaille <akim@epita.fr>
17650 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
17651 which have no values.
17653 2002-02-05 Akim Demaille <akim@epita.fr>
17655 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
17658 2002-01-29 Paul Eggert <eggert@twinsun.com>
17660 * src/bison.simple (YYSIZE_T): Do not define merely because
17661 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
17662 On some platforms, <alloca.h> does not declare YYSTD (size_t).
17664 2002-01-27 Akim Demaille <akim@epita.fr>
17666 Fix `%nonassoc and eof'.
17668 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
17669 which were not properly copied! Replace
17670 memcpy (res->errs, src->errs, src->nerrs);
17672 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
17674 * tests/regression.at (%nonassoc and eof): Adjust to newest
17675 Autotest: `.' is not in the PATH.
17677 2002-01-27 Akim Demaille <akim@epita.fr>
17679 * tests/sets.at (AT_EXTRACT_SETS): New.
17680 (Nullable): Use it.
17683 2002-01-26 Akim Demaille <akim@epita.fr>
17685 * tests/actions.at, tests/calc.at, tests/headers.at,
17686 * tests/torture.at: Adjust to the newest Autotest which no longer
17687 forces `.' in the PATH.
17689 2002-01-25 Akim Demaille <akim@epita.fr>
17691 * tests/regression.at (%nonassoc and eof): New.
17692 Suggested by Robert Anisko.
17694 2002-01-24 Akim Demaille <akim@epita.fr>
17696 Bison dumps core when trying to complain about broken input files.
17697 Reported by Cris van Pelt.
17699 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
17700 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
17702 (Invalid inputs): Strengthen: exercise parse_percent_token.
17704 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
17706 * src/Makefile.am: Add bison.c++.
17707 * src/bison.c++: New skeleton.
17709 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
17713 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
17715 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
17717 2002-01-20 Marc Autret <marc@gnu.org>
17719 * src/files.c (compute_output_file_names): Fix
17721 2002-01-20 Marc Autret <marc@gnu.org>
17723 * tests/output.at: New test.
17724 * src/files.c (compute_base_names): Don't map extensions when
17725 the YACC flag is set, use defaults.
17726 Reported by Evgeny Stambulchik.
17728 2002-01-20 Marc Autret <marc@gnu.org>
17730 * src/system.h: Need to define __attribute__ away for non-GCC
17731 compilers as well (i.e., the vendor C compiler).
17732 Suggested by Albert Chin-A-Young.
17734 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
17736 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
17737 canonical definition.
17738 * src/system.h: Use the canonical definition for PARAMS (avoids
17739 a conflict with the macro from lib/hash.h).
17741 2002-01-11 Akim Demaille <akim@epita.fr>
17743 * configure.in: Use AC_FUNC_STRNLEN.
17744 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
17746 2002-01-09 Akim Demaille <akim@epita.fr>
17748 * src/files.c, src/files.h (output_infix): New.
17749 (tab_extension): Remove.
17750 (compute_base_names): Compute the former, drop the latter.
17751 * src/output.c (prepare): Insert the muscles `output-infix', and
17753 * src/parse-skel.y (string, string.1): New.
17754 (section.header): Use it.
17755 (section.yacc): Remove.
17756 (prefix): Remove too.
17757 * src/scan-skel.l: Adjust.
17758 * src/bison.simple, src/bison.hairy: Adjust.
17760 2002-01-09 Akim Demaille <akim@epita.fr>
17762 * configure.in (WERROR_CFLAGS): Compute it.
17763 * src/Makefile.am (CFLAGS): Pass it.
17764 * tests/atlocal.in (CFLAGS): Idem.
17765 * src/files.c: Fix a few warnings.
17766 (get_extension_index): Remove, unused.
17768 2002-01-08 Akim Demaille <akim@epita.fr>
17770 * src/getargs.c (AS_FILE_NAME): New.
17771 (getargs): Use it to convert DOSish file names.
17772 * src/files.c (base_name): Rename as full_base_name to avoid
17773 clashes with `base_name ()'.
17774 (filename_split): New.
17775 (compute_base_names): N-th rewrite, using filename_split.
17777 2002-01-08 Akim Demaille <akim@epita.fr>
17779 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
17780 New, stolen from the Fileutils 4.1.
17781 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
17782 * configure.in: Check for the presence of memrchr, and of its
17785 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
17787 * lib/hash.h (__P): Added definition for this macro.
17788 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
17789 BUILT_SOURCES, to ensure they are generated first.
17790 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
17791 %error-verbose to allow bootstrapping with bison 1.30x.
17793 2002-01-06 Akim Demaille <akim@epita.fr>
17795 * src/reader.c (parse_braces): Don't fetch the next char, the
17796 convention is to fetch on entry.
17797 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
17798 'switch' without a following semicolon.
17799 * tests/regression.at (braces parsing): New.
17801 2002-01-06 Akim Demaille <akim@epita.fr>
17803 Bison is dead wrong in its RR conflict reports.
17805 * tests/torture.at (GNU Cim Grammar): New.
17806 * src/conflicts.c (count_rr_conflicts): Fix.
17808 2002-01-06 Akim Demaille <akim@epita.fr>
17810 Creating package.m4 from configure.ac causes too many problems.
17812 * tests/Makefile.am (package.m4): Create it by hand,
17813 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
17815 2002-01-06 Akim Demaille <akim@epita.fr>
17817 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
17820 2002-01-04 Paul Eggert <eggert@twinsun.com>
17822 * doc/bison.texinfo (Debugging):
17823 Remove YYSTDERR; it's no longer defined or used.
17824 Also, s/cstdio.h/cstdio/.
17826 2002-01-03 Akim Demaille <akim@epita.fr>
17828 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
17830 2002-01-03 Akim Demaille <akim@epita.fr>
17832 * src/parse-skel.y (process_skeleton): Don't bind the parser's
17833 tracing code to --trace, wait for a better --trace option, with
17836 2002-01-03 Akim Demaille <akim@epita.fr>
17838 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
17839 The ISO C++ standard is extremely clear about it: stderr is
17840 considered a macro, not a regular symbol (see table 94 `Header
17841 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
17842 Therefore std:: does not apply to it. It still does with fprintf.
17843 Also, s/cstdio.h/cstdio/.
17845 2002-01-03 Akim Demaille <akim@epita.fr>
17847 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
17848 for non system headers.
17850 2002-01-02 Akim Demaille <akim@epita.fr>
17852 Equip the skeleton chain with location tracking, runtime trace,
17853 pure parser and scanner.
17855 * src/parse-skel.y: Request a pure parser, locations, and prefix
17857 (%union): Having several members with the same type does not help
17858 type mismatches, simplify.
17859 (YYPRINT, yyprint): New.
17860 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
17861 (skel_error): this.
17863 * src/scan-skel.l: Adjust to these changes.
17864 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
17865 (LOCATION_PRINT, skel_control_t): New.
17867 2001-12-30 Akim Demaille <akim@epita.fr>
17869 * src/parse-skel.y: Get rid of the shift/reduce conflict:
17870 replace `gb' with BLANKS.
17871 * src/scan-skel.l: Adjust.
17873 2001-12-30 Akim Demaille <akim@epita.fr>
17875 * src/system.h: We don't need nor want bcopy.
17876 Throw away MS-DOS crap: we don't need getpid.
17877 * configure.in: We don't need strndup. It was even causing
17878 problems: because Flex includes the headers *before* us,
17879 _GNU_SOURCE is not defined by config.h, and therefore strndup was
17881 * lib/xstrndup.c: New.
17882 * src/scan-skel.l: Use it.
17883 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
17884 * src/parse-skel.y: Use %directives instead of #defines.
17886 2001-12-30 Akim Demaille <akim@epita.fr>
17888 * src/skeleton.h: New.
17889 * src/output.c (output_parser, output_master_parser): Remove, dead
17891 * src/output.h (get_lines_number, actions_output, guards_output)
17892 (token_definitions_output): Prototype them.
17893 * src/parse-skel.y: Add the license notice.
17894 Include output.h and skeleton.h.
17895 (process_skeleton): Returns void, and takes a single parameter.
17896 * src/scan-skel.l: Add the license notice.
17897 Include skeleton.h.
17898 Don't use %option yylineno: it seems that then Flex imagines
17899 REJECT has been used, and therefore it won't reallocate its
17900 buffers (which makes no other sense to me than a bug). It results
17901 in warnings for `unused: yy_flex_realloc'.
17903 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
17905 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
17906 (MUSCLE_INSERT_PREFIX): ...to there.
17907 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
17908 (MUSCLE_INSERT_PREFIX): Move from here...
17910 * src/bison.hairy: Add a section directive. Put braces around muscle
17911 names. This parser skeleton is still broken, but Bison should not
17912 choke on a bad muscle 'syntax'.
17913 * src/bison.simple: Add a section directive. Put braces around muscle
17916 * src/files.h (strsuffix, stringappend): Add declarations.
17917 (tab_extension): Add declaration.
17918 (short_base_name): Add declaration.
17920 * src/files.c (strsuffix, stringappend): No longer static. These
17921 functions are used in the skeleton parser.
17922 (tab_extension): New.
17923 (compute_base_names): Use the computations done in this function
17924 to guess if the generated parsers should have '.tab' in their
17926 (short_base_name): No longer static.
17928 * src/output.c (output_skeleton): New.
17929 (output): Disable call to output_master_parser, and give a try to
17930 a new skeleton handling system.
17931 (guards_output, actions_output): No longer static.
17932 (token_definitions_output, get_lines_number): No longer static.
17934 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
17936 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
17939 * src/parse-skel.y: New file.
17940 * src/scan-skel.l: New file.
17942 2001-12-29 Akim Demaille <akim@epita.fr>
17944 %name-prefix is broken.
17946 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
17947 Adjust all dependencies.
17948 * tests/headers.at (export YYLTYPE): Strengthen this test: use
17951 Renaming yylval but not yylloc is not consistent. Now we do.
17953 * src/bison.simple: Prefix yylloc if used.
17954 * doc/bison.texinfo (Decl Summary): Document that.
17956 2001-12-29 Akim Demaille <akim@epita.fr>
17958 * doc/bison.texinfo: Promote `%long-directive' over
17960 Remove all references to fixed-output-files, yacc is enough.
17962 2001-12-29 Akim Demaille <akim@epita.fr>
17964 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
17965 user prologue. These are defaults.
17966 * tests/actions.at (Mid-rule actions): Make sure the user can
17967 define YYDEBUG and YYERROR_VERBOSE.
17969 2001-12-29 Akim Demaille <akim@epita.fr>
17971 * src/output.c (header_output): Don't forget to export YYLTYPE and
17973 * tests/headers.at (export YYLTYPE): New, make sure it does.
17974 * tests/regression.at (%union and --defines, Invalid CPP headers):
17976 * tests/headers.at: here.
17978 2001-12-29 Akim Demaille <akim@epita.fr>
17980 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
17982 2001-12-29 Akim Demaille <akim@epita.fr>
17984 * tests/actions.at (Mid-rule actions): Output on a single line
17985 instead of several.
17987 2001-12-29 Akim Demaille <akim@epita.fr>
17989 * doc/bison.texinfo: Formatting changes.
17991 2001-12-29 Akim Demaille <akim@epita.fr>
17993 Don't store the token defs in a muscle, just be ready to output it
17994 on command. Now possible via `symbols'. Fixes a memory leak.
17996 * src/output.c (token_definitions_output): New.
17997 (output_parser, header_output): Use it.
17998 * src/reader.c (symbols_save): Remove.
18000 2001-12-29 Akim Demaille <akim@epita.fr>
18002 * src/bison.simple: Do not provide a default for YYSTYPE and
18003 YYLTYPE before the user's prologue. Otherwise it's hardly... a
18006 2001-12-29 Akim Demaille <akim@epita.fr>
18008 Mid-rule actions are simply... ignored!
18010 * src/reader.c (readgram): Be sure to attach mid-rule actions to
18011 the empty-rule associated to the dummy symbol, not to the host
18013 * tests/actions.at (Mid-rule actions): New.
18015 2001-12-29 Akim Demaille <akim@epita.fr>
18019 * src/reader.c (reader): Free grammar.
18021 2001-12-29 Akim Demaille <akim@epita.fr>
18025 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
18026 since it allocates it for each state, although only one is needed.
18027 (allocate_storage): Do it here.
18029 2001-12-29 Akim Demaille <akim@epita.fr>
18031 * src/options.h, src/options.c (create_long_option_table): Rename
18033 (long_option_table_new): this, with a clearer prototype.
18034 (percent_table): Remove, unused,
18035 * src/getargs.c (getargs): Adjust.
18037 2001-12-29 Akim Demaille <akim@epita.fr>
18039 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
18040 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
18043 2001-12-29 Akim Demaille <akim@epita.fr>
18045 * src/lalr.c (build_relations): Rename `states' as `states1'.
18046 Sorry, I don't understand exactly what it is, no better name...
18048 2001-12-29 Akim Demaille <akim@epita.fr>
18050 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
18051 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
18052 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
18055 2001-12-29 Akim Demaille <akim@epita.fr>
18057 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
18060 2001-12-29 Akim Demaille <akim@epita.fr>
18062 * src/reader.c, src/reader.h (user_toknums): Remove.
18063 Adjust all users to use symbols[i]->user_token_number.
18065 2001-12-29 Akim Demaille <akim@epita.fr>
18067 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
18068 Adjust all users to use symbols[i]->prec or ->assoc.
18070 2001-12-29 Akim Demaille <akim@epita.fr>
18072 * src/reader.c, src/reader.h (tags): Remove.
18073 Adjust all users to use symbols[i]->tag.
18075 2001-12-29 Akim Demaille <akim@epita.fr>
18077 * src/gram.h, src/gram.c (symbols): New, similar to state_table
18079 * src/reader.c (packsymbols): Fill this table.
18081 * src/conflicts.c (resolve_sr_conflict): Adjust.
18082 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
18084 Use symbols[i]->tag instead of tags[i].
18086 2001-12-29 Akim Demaille <akim@epita.fr>
18088 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
18089 In addition, put a comment in there, to replace...
18090 * tests/regression.at (%union and C comments): Remove.
18092 2001-12-29 Akim Demaille <akim@epita.fr>
18094 * tests/regression.at (Web2c Actions): Blindly move the actual
18095 output as expected output. The contents *seem* right to me, but I
18096 can't pretend reading perfectly parser tables... Nonetheless, all
18097 the other tests pass correctly, the table look OK, even though the
18098 presence of `$axiom' is to be noted: AFAICS it is useless (but
18101 2001-12-29 Akim Demaille <akim@epita.fr>
18103 * src/reader.c (readgram): Don't add the rule 0 if there were no
18104 rules read. In other words, add it _after_ having performed
18105 grammar sanity checks.
18106 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
18108 2001-12-29 Akim Demaille <akim@epita.fr>
18110 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
18111 visible, and some states have now a different number.
18113 2001-12-29 Akim Demaille <akim@epita.fr>
18115 * src/reader.c (readgram): Bind the initial rule's lineno to that
18117 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
18118 (Solved SR Conflicts): Adjust rule 0's line number.
18120 2001-12-29 Akim Demaille <akim@epita.fr>
18122 Fix the `GAWK Grammar' failure.
18124 * src/LR0.c (final_state): Initialize to -1 so that we do compute
18125 the reductions of the first state which was mistakenly confused
18126 with the final state because precisely final_state was initialized
18128 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
18129 now noticed by Bison.
18130 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
18131 have a reduction on $default.
18133 2001-12-29 Akim Demaille <akim@epita.fr>
18135 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
18137 * src/closure.c (print_closure): Likewise.
18138 * src/derives.c (print_derives): Likewise.
18139 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
18142 2001-12-29 Akim Demaille <akim@epita.fr>
18144 * src/lalr.c (lookaheads_print): New.
18145 (lalr): Call it when --trace-flag.
18146 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
18149 2001-12-29 Akim Demaille <akim@epita.fr>
18151 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
18152 when walking through ritem, even via rule->rhs.
18153 * src/reduce.c (dump_grammar, useful_production, reduce_output)
18154 (useful_production, useless_nonterminals): Likewise.
18155 (reduce_grammar_tables): Likewise, plus update nritems.
18156 * src/nullable.c (set_nullable): Likewise.
18157 * src/lalr.c (build_relations): Likewise.
18158 * tests/sets.at (Nullable): Adjust.
18159 Fortunately, now, the $axiom is no longer nullable.
18161 2001-12-29 Akim Demaille <akim@epita.fr>
18163 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
18165 * src/gram.c (ritem_longest_rhs): Likewise.
18166 * src/reduce.c (nonterminals_reduce): Likewise.
18167 * src/print_graph.c (print_graph): Likewise.
18168 * src/output.c (output_rule_data): Likewise.
18169 * src/nullable.c (set_nullable): Likewise.
18171 2001-12-29 Akim Demaille <akim@epita.fr>
18173 * src/output.c: Comment changes.
18175 2001-12-27 Paul Eggert <eggert@twinsun.com>
18177 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
18178 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
18179 Sparc, as they were causing more porting problems than the
18180 (minor) performance improvement was worth.
18182 Also, catch up with 1.31's YYSTD.
18184 2001-12-27 Akim Demaille <akim@epita.fr>
18186 * src/output.c (output_gram): Rely on nritems, not the
18187 0-sentinel. See below.
18188 Use -1 as separator, not 0.
18189 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
18190 Rely on -1 as separator in yyrhs, instead of 0.
18191 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
18192 twice `Now at end of input', therefore there are two lines less to
18195 2001-12-27 Akim Demaille <akim@epita.fr>
18197 * tests/regression.at (Unresolved SR Conflicts):
18198 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
18201 2001-12-27 Akim Demaille <akim@epita.fr>
18203 * src/LR0.c (new_state): Recognize the final state by the fact it
18204 is reached by eoftoken.
18205 (insert_start_shifting_state, insert_eof_shifting_state)
18206 (insert_accepting_state, augment_automaton): Remove, since now
18207 these states are automatically computed from the initial state.
18208 (generate_states): Adjust.
18209 * src/print.c: When reporting a rule number to the user, substract
18210 1, so that the axiom rule is rule 0, and the first user rule is 1.
18211 * src/reduce.c: Likewise.
18212 * src/print_graph.c (print_core): For the time being, just as for
18213 the report, depend upon --trace-flags to dump the full set of
18215 * src/reader.c (readgram): Once the grammar read, insert the rule
18216 0: `$axiom: START-SYMBOL $'.
18217 * tests/set.at: Adjust: rule 0 is now displayed, and since the
18218 number of the states has changed (the final state is no longer
18219 necessarily the last), catch up.
18221 2001-12-27 Akim Demaille <akim@epita.fr>
18223 Try to make the use of the eoftoken valid. Given that its value
18224 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
18225 is used instead of > 0 where appropriate, (ii), depend upon nritems
18226 instead of the 0-sentinel.
18228 * src/gram.h, src/gram.c (nritems): New.
18229 Expected to be duplication of nitems, but for the time being...
18230 * src/reader.c (packgram): Assert nritems and nitems are equal.
18231 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
18232 * src/closure.c (print_closure, print_fderives): Likewise.
18233 * src/gram.c (ritem_print): Likewise.
18234 * src/print.c (print_core, print_grammar): Likewise.
18235 * src/print_graph.c: Likewise.
18237 2001-12-27 Akim Demaille <akim@epita.fr>
18239 * src/main.c (main): If there are complains after grammar
18240 reductions, then output the report anyway if requested, then die.
18241 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
18242 * src/reader.c (eoftoken): New.
18243 (parse_token_decl): If the token being defined has value `0', it
18245 (packsymbols): No longer hack `tags' to insert `$' by hand.
18246 Be sure to preserve the value of the eoftoken.
18247 (reader): Make sure eoftoken is defined.
18248 Initialize nsyms to 0: now eoftoken is created just like the others.
18249 * src/print.c (print_grammar): Don't special case the eof token.
18250 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
18251 lie anyway, albeit pleasant.
18252 * tests/calc.at: Exercise error messages with eoftoken.
18253 Change the grammar so that empty input is invalid.
18254 Adjust expectations.
18255 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
18257 2001-12-27 Akim Demaille <akim@epita.fr>
18259 * configure.in: Check the protos of strchr ans strspn.
18260 Replace strchr if needed.
18261 * src/system.h: Provide the protos of strchr, strspn and memchr if
18263 * lib/strchr.c: New.
18264 * src/reader.c (symbols_save): Use strchr.
18266 2001-12-27 Akim Demaille <akim@epita.fr>
18268 * src/print.c, src/print_graph.c (escape): New.
18269 Use it to quote the TAGS outputs.
18270 * src/print_graph.c (print_state): Now errors are in red, and
18271 reductions in green.
18272 Prefer high to wide: output the state number on a line of its own.
18274 2001-12-27 Akim Demaille <akim@epita.fr>
18276 * src/state.h, src/state.c (reductions_new): New.
18277 * src/LR0.c (set_state_table): Let all the states have a
18278 `reductions', even if reduced to 0.
18279 (save_reductions): Adjust.
18280 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
18281 * src/print.c (print_reductions, print_actions): Adjust.
18282 * src/output.c (action_row): Adjust.

18290 * src/output.c (output_actions, action_row): Adjust.
18291 * src/conflicts.c (resolve_sr_conflict): Adjust.
18293 2001-12-27 Akim Demaille <akim@epita.fr>
18295 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
18297 2001-12-27 Akim Demaille <akim@epita.fr>
18299 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
18300 * src/print.c: here.
18301 (lookaheadset, shiftset): New, used as additional storage by
18303 (print_results): Adjust.
18304 (print_shifts, print_gotos, print_errs): New, extracted from...
18305 (print_actions): here.
18306 * src/print_graph.c (print_actions): Remove dead code.
18308 2001-12-27 Akim Demaille <akim@epita.fr>
18310 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
18313 2001-12-27 Akim Demaille <akim@epita.fr>
18315 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
18316 (build_relations): Adjust.
18318 2001-12-27 Akim Demaille <akim@epita.fr>
18320 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
18323 2001-12-27 Akim Demaille <akim@epita.fr>
18325 * src/reader.c (packgram): Catch nitems overflows.
18327 2001-12-27 Akim Demaille <akim@epita.fr>
18329 * src/files.c, src/files.h (guard_obstack): Remove.
18330 * src/output.c (output): Adjust.
18331 * src/reader.c (parse_braces): New, factoring...
18332 (copy_action, copy_guard): these two which are renamed as...
18333 (parse_action, parse_guard): these.
18334 As a voluntary consequence, using braces around guards is now
18337 2001-12-27 Akim Demaille <akim@epita.fr>
18339 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
18340 * src/reader.c (symbol_list): `guard' and `guard_line' are new
18342 (symbol_list_new): Adjust.
18343 (copy_action): action_line is the first line, not the last.
18344 (copy_guard): Just as for actions, store the `action' only, not
18345 the switch/case/break flesh.
18346 Don't parse the user action that might follow the guard, let...
18347 (readgram): do it, i.e., now, there can be an action after a
18349 In other words the guard is just explicitly optional.
18350 (packgram): Adjust.
18351 * src/output.c (guards_output): New.
18352 (output_parser): Call it when needed.
18353 (output): Also free the guard and attrs obstacks.
18354 * src/files.c, src/files.h (obstack_save): Remove.
18355 (output_files): Remove.
18356 As a result, if one needs the former `.act' file, using an
18357 appropriate skeleton which requires actions and guards is now
18359 * src/main.c (main): Adjust.
18360 * tests/semantic.at: New.
18361 * tests/regression.at: Use `input.y' as input file name.
18362 Avoid 8+3 problems by requiring input.c when the test needs the
18365 2001-12-27 Akim Demaille <akim@epita.fr>
18367 * src/reader.c (symbol_list_new): Be sure to initialize all the
18370 2001-12-27 Akim Demaille <akim@epita.fr>
18372 All the hacks using a final pseudo state are now useless.
18374 * src/LR0.c (set_state_table): state_table holds exactly nstates.
18375 * src/lalr.c (nLA): New.
18376 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
18377 instead of lookaheadsp from the pseudo state (nstate + 1).
18379 2001-12-27 Akim Demaille <akim@epita.fr>
18381 * src/output.c (action_row, token_actions): Use a state_t instead
18382 of a integer, and nlookaheads instead of the following state's

18387 * src/conflicts.c (log_resolution, flush_shift)
18388 (resolve_sr_conflict, set_conflicts, solve_conflicts)
18389 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
18390 (conflicts_print, print_reductions): Use a state_t instead of an
18391 integer when referring to a state.
18392 As much as possible, depend upon nlookaheads, instead of the
18393 `lookaheadsp' member of the following state (since lookaheads of
18394 successive states are successive, the difference between state n + 1
18395 and n served as the number of lookaheads for state n).
18396 * src/lalr.c (add_lookback_edge): Likewise.
18397 * src/print.c (print_core, print_actions, print_state)
18398 (print_results): Likewise.
18399 * src/print_graph.c (print_core, print_actions, print_state)
18400 (print_graph): Likewise.

18408 Add plenty of `static'.
18410 2001-12-27 Akim Demaille <akim@epita.fr>
18412 * src/output.c (prepare): Drop the muscle `ntbase' which
18413 duplicates ntokens.
18414 * src/bison.simple: Formatting/comment changes.
18415 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
18416 is an undocumented synonym.
18418 2001-12-22 Akim Demaille <akim@epita.fr>
18420 * src/output.c (output_table_data): Change the prototype to use
18421 `int' for array ranges: some invocations do pass an int, not a
18423 Reported by Wayne Green.
18425 2001-12-22 Akim Demaille <akim@epita.fr>
18427 Some actions of web2c.y are improperly triggered.
18428 Reported by Mike Castle.
18430 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
18431 * tests/regression.at (Web2c): Rename as...
18432 (Web2c Report): this.
18433 (Web2c Actions): New.
18435 2001-12-22 Akim Demaille <akim@epita.fr>
18437 Reductions in web2c.y are improperly reported.
18438 Reported by Mike Castle.
18440 * src/conflicts.c (print_reductions): Fix.
18441 * tests/regression.at (Web2c): New.
18443 2001-12-18 Akim Demaille <akim@epita.fr>
18445 Some host fail on `assert (!"foo")', which expands to
18446 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
18447 Reported by Nelson Beebee.
18449 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
18450 `#define it_succeeded 0' and `assert (it_succeeded)'.
18452 2001-12-17 Marc Autret <autret_m@epita.fr>
18454 * src/bison.simple: Don't hard code the skeleton line and filename.
18455 * src/output.c (output_parser): Rename 'line' as 'output_line'.
18456 New line counter 'skeleton_line' (skeleton-line muscle).
18458 2001-12-17 Paul Eggert <eggert@twinsun.com>
18460 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
18461 YYDEBUG must be defined to a nonzero value.
18463 * src/bison.simple (yytname): Do not assume that the user defines
18464 YYDEBUG to a properly parenthesized expression.
18466 2001-12-17 Akim Demaille <akim@epita.fr>
18468 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
18469 nlookaheads is a new member.
18471 * src/lalr.h (nlookaheads): Remove this orphan declaration.
18472 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
18475 2001-12-17 Akim Demaille <akim@epita.fr>
18477 * src/files.h, src/files.c (open_files, close_files): Remove.
18478 * src/main.c (main): Don't open/close files, nor invoke lex_free,
18480 * src/reader.c (reader): Do it.
18482 2001-12-17 Akim Demaille <akim@epita.fr>
18484 * src/conflicts.c (print_reductions): Formatting changes.
18486 2001-12-17 Akim Demaille <akim@epita.fr>
18488 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
18489 (flush_reduce): New.

18492 2001-12-17 Akim Demaille <akim@epita.fr>
18494 * src/output.c (output_obstack): Be static and rename as...
18495 (format_obstack): this, to avoid any confusion with files.c's
18497 * src/reader.h (muscle_obstack): Move to...
18498 * src/output.h: here, since it's defined in output.c.
18500 2001-12-17 Akim Demaille <akim@epita.fr>
18502 * src/output.c (action_row, save_column, default_goto)
18503 (sort_actions, matching_state, pack_vector): Better variable
18506 2001-12-17 Akim Demaille <akim@epita.fr>
18508 * src/output.c: Various formatting changes.
18510 2001-12-17 Akim Demaille <akim@epita.fr>
18512 * src/files.c (output_files): Free the output_obstack.
18513 * src/main.c (main): Call print and print_graph conditionally.
18514 * src/print.c (print): Work unconditionally.
18515 * src/print_graph.c (print_graph): Work unconditionally.
18516 * src/conflicts.c (log_resolution): Output only if verbose_flag.
18518 2001-12-16 Marc Autret <autret_m@epita.fr>
18520 * src/output.c (actions_output): Fix. When we use %no-lines,
18521 there is one less line per action.
18523 2001-12-16 Marc Autret <autret_m@epita.fr>
18525 * src/bison.simple: Remove a useless #line directive.
18526 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
18527 * src/output.c (get_lines_number): New.
18528 (output_parser): Adjust, now takes care about the lines of a
18530 Fix line numbering.
18531 (actions_output): Computes the number of lines taken by actions.
18532 (output_master_parser): Insert new skeleton which is the name of
18533 the output parser file name.
18535 2001-12-15 Marc Autret <autret_m@epita.fr>
18537 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
18539 2001-12-15 Marc Autret <autret_m@epita.fr>
18541 * src/output.c (output_gram): Keep track of the hairy one.
18543 2001-12-15 Akim Demaille <akim@epita.fr>
18545 Make `make distcheck' work.
18547 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
18548 system.h which uses libgettext.h.
18550 2001-12-15 Akim Demaille <akim@epita.fr>
18552 * src/nullable.c (set_nullable): Useless rules must be skipped,
18553 otherwise, since we range over their symbols, we might look at a
18554 nonterminal which no longer ``exists'', i.e., it is not counted in
18555 `nvars', hence we overflow our arrays.
18557 2001-12-15 Akim Demaille <akim@epita.fr>
18559 The header can also be produced directly, without any obstack!
18562 * src/files.c, src/files.h (defines_obstack): Remove.
18563 (compute_header_macro): Global.
18564 (defines_obstack_save): Remove.
18565 * src/reader.c (parse_union_decl): No longer output to
18566 defines_obstack: its content can be found in the `stype' muscle
18568 (output_token_translations): Merge into...
18569 (symbols_output): this.
18571 (symbols_save): this.
18573 * src/output.c (header_output): New.
18576 2001-12-15 Akim Demaille <akim@epita.fr>
18578 * src/reader.c (parse_union_decl): Instead of handling two obstack
18579 simultaneously, use one to define the `stype' muscle, and use the
18580 value of the latter to fill defines_obstack.
18581 (copy_comment): Remove.
18582 (copy_comment2): Work for a single obstack.
18584 (copy_comment): this.
18586 2001-12-15 Akim Demaille <akim@epita.fr>
18588 * src/lex.c, src/lex.h (xgetc): No longer static.
18589 * src/reader.c (parse_union_decl): Revamp.
18591 2001-12-15 Akim Demaille <akim@epita.fr>
18593 Still making progress in separating Bison into (i) input, (ii)
18594 process, (iii) output: now we can directly output the parser file
18595 without using table_obstack at all.
18597 * src/files.c, src/files.h (table_obstack): Bye bye.
18598 (parser_file_name): New.
18599 * src/files.c (compute_output_file_names): Compute it.
18600 * src/output.c (actions_output, output_parser)
18601 (output_master_parser): To a file instead of an obstack.
18603 2001-12-15 Akim Demaille <akim@epita.fr>
18605 Attach actions to rules, instead of pre-outputting them to
18608 * src/gram.h (rule_t): action and action_line are new members.
18609 * src/reader.c (symbol_list): Likewise.
18610 (copy_action): Save the actions within the rule.
18611 (packgram): Save them in rule_table.
18612 * src/output.c (actions_output): New.
18613 (output_parser): Use it on `%%actions'.
18614 (output_rule_data): Don't free rule_table.
18616 (prepare): Don't save the `action' muscle.
18617 * src/bison.simple: s/%%action/%%actions/.
18619 2001-12-15 Akim Demaille <akim@epita.fr>
18621 * src/reader.c (copy_action): When --yacc, don't append a `;'
18622 to the user action: let it fail if lacking.
18623 Suggested by Arnold Robbins and Tom Tromey.
18625 2001-12-14 Akim Demaille <akim@epita.fr>
18627 * src/lex.c (literalchar): Simply return the char you decoded, non
18628 longer mess around with obstacks and int pointers.
18629 Adjust all callers.
18631 2001-12-14 Akim Demaille <akim@epita.fr>
18633 * src/lex.c (literalchar): Don't escape the special characters,
18634 just decode them, and keep them as char (before, eol was output as
18635 the 2 char string `\n' etc.).
18636 * src/output.c (output_rule_data): Use quotearg to output the
18639 2001-12-13 Paul Eggert <eggert@twinsun.com>
18641 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
18642 Do not infringe on the global user namespace when using C++.
18643 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
18644 All uses of `fprintf' and `stderr' changed.
18646 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
18648 2001-12-13 Akim Demaille <akim@epita.fr>
18650 The computation of nullable is broken: it doesn't handle empty
18653 * tests/torture.at (GNU AWK Grammar): New.
18654 * tests/sets.at (Nullable): New.
18655 * src/nullable.c (set_nullable): Instead of blindly looping over
18656 `ritems', loop over the rules, and then over their rhs's.
18658 Work around Autotest bugs.
18660 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
18661 frame, because Autotest understand lines starting with a `+' as
18662 traces from the shell. Then, they are not processed properly.
18663 Admittedly an Autotest bug, but we don't have time to wait for
18664 Autotest to catch up.
18665 * tests/regression.at (Broken Closure): Adjust to the new table
18668 * tests/sets.at: here.
18670 2001-12-13 Akim Demaille <akim@epita.fr>
18672 * src/closure.c (closure): Use nrules instead of playing tricks
18673 with BITS_PER_WORD.
18675 2001-12-13 Akim Demaille <akim@epita.fr>
18677 * src/print.c (print_actions): Output the handling of `$' as the
18678 traces do: shifting the token EOF. Before EOF was treated as a
18680 * tests/regression.at: Adjust some tests.
18681 * src/print_graph.c (print_core): Complete the set of items via
18682 closure. The next-to-final and final states are still unsatisfying,
18683 but that's to be addressed elsewhere.
18684 No longer output the rule numbers, but do output the state number.
18685 A single loop for the shifts + gotos is enough, but picked a
18686 distinct color for each.
18687 (print_graph): Initialize and finalize closure.
18689 2001-12-13 Akim Demaille <akim@epita.fr>
18691 * src/reader.c (readgram): Remove dead code, an strip useless
18693 (get_type): Remove, unused.
18695 2001-12-12 Akim Demaille <akim@epita.fr>
18697 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
18698 on that of lib/error.c.
18700 2001-12-12 Akim Demaille <akim@epita.fr>
18702 Some hosts don't like `/' in includes.
18704 * src/system.h: Include libgettext.h without qualifying the path.
18705 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
18708 2001-12-11 Marc Autret <autret_m@epita.fr>
18710 * src/output.c (output_parser): Remove useless muscle.
18712 2001-12-11 Marc Autret <autret_m@epita.fr>
18714 * src/bison.simple: Remove #line just before %%epilogue. It
18715 is now handled in ...
18716 * src/reader.c (read_additionnal_code): Add the output of a
18717 #line for the epilogue.
18719 2001-12-10 Marc Autret <autret_m@epita.fr>
18721 * src/reader.c (copy_definition): Re-use CPP-outed code which
18722 replace precedent remove.
18723 * src/bison.simple: Remove #line before %%prologue because
18724 %%input-line is wrong at this time.
18726 2001-12-10 Marc Autret <autret_m@epita.fr>
18728 * src/reader.c (symbols_output): Clean up.
18729 * src/output.c (output_gram, output): Clean up.
18731 2001-12-10 Akim Demaille <akim@epita.fr>
18733 * src/lalr.c (initialize_lookaheads): New. Extracted from...
18734 * src/LR0.c (set_state_table): here.
18735 * src/lalr.c (lalr): Call it.
18737 2001-12-10 Akim Demaille <akim@epita.fr>
18739 * src/state.h (shifts): Remove the `number' member: shifts are
18740 attached to state, hence no longer need to be labelled with a
18743 2001-12-10 Akim Demaille <akim@epita.fr>
18745 Now that states have a complete set of members, the linked list of
18746 shifts is useless: just fill directly the state's shifts member.
18748 * src/state.h (shifts): Remove the `next' member.
18749 * src/LR0.c (first_state, last_state): Remove.
18750 Adjust the callers.
18751 (augment_automaton): Don't look for the shifts that must be added
18752 a shift on EOF: it is those of the state we looked for! But now,
18753 since shifts are attached, it is no longer needed to looking
18754 merely by its id: its number.
18756 2001-12-10 Akim Demaille <akim@epita.fr>
18758 * src/LR0.c (augment_automaton): Better variable locality.
18759 Remove an impossible branch: if there is a state corresponding to
18760 the start symbol being shifted, then there is shift for the start
18761 symbol from the initial state.
18763 2001-12-10 Akim Demaille <akim@epita.fr>
18765 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
18766 only when appropriate: when insert_start_shifting_state' is not
18768 * tests/regression.at (Rule Line Numbers): Adjust.
18770 2001-12-10 Akim Demaille <akim@epita.fr>
18772 * src/LR0.c (augment_automaton): Now that all states have shifts,
18773 merge the two cases addition shifts to the initial state.
18775 2001-12-10 Akim Demaille <akim@epita.fr>
18777 * src/lalr.c (set_state_table): Move to...
18779 * src/lalr.c (lalr): Don't call it...
18780 * src/LR0.c (generate_states): do it.
18781 * src/LR0.h (first_state): Remove, only the table is used.
18783 2001-12-10 Akim Demaille <akim@epita.fr>
18785 * src/LR0.h (first_shift, first_reduction): Remove.
18786 * src/lalr.c: Don't use first_shift: find shifts through the
18789 2001-12-10 Akim Demaille <akim@epita.fr>
18791 * src/LR0.c: Attach shifts to states as soon as they are
18793 * src/lalr.c (set_state_table): Instead of assigning shifts to
18794 state, just assert that the mapping was properly done.
18796 2001-12-10 Akim Demaille <akim@epita.fr>
18798 * src/LR0.c (insert_start_shift): Rename as...
18799 (insert_start_shifting_state): this.
18800 (insert_eof_shifting_state, insert_accepting_state): New.
18801 (augment_automaton): Adjust.
18802 Better locality of the variables.
18803 When looking if the start_symbol is shifted from the initial
18804 state, using `while (... symbol != start_symbol ...)' sounds
18805 better than `while (... symbol < start_symbol ...)': If fail
18806 to see how the order between symbols could be relevant!
18808 2001-12-10 Akim Demaille <akim@epita.fr>
18810 * src/getargs.h: Don't declare `spec_name_prefix' and
18811 `spec_file_prefix', declared by src/files.h.
18812 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
18813 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
18814 * src/output.c (prepare): Adjust.
18815 * src/reader.c (symbols_output): Likewise.
18816 * src/vmsgetargs.c: Vaguely adjust, but who cares?
18818 2001-12-10 Akim Demaille <akim@epita.fr>
18820 * src/muscle_tab.c (muscle_init): NULL is a better default than
18823 2001-12-10 Akim Demaille <akim@epita.fr>
18825 * src/reader.c (reader): Calling symbols_output once is enough.
18827 2001-12-10 Akim Demaille <akim@epita.fr>
18829 Now that states have a complete set of members, the linked list of
18830 reductions is useless: just fill directly the state's reductions
18833 * src/state.h (struct reductions): Remove member `number' and
18835 * src/LR0.c (first_reduction, last_reduction): Remove.
18836 (save_reductions): Don't link the new reductions, store them in
18838 * src/lalr.c (set_state_table): No need to attach reductions to
18839 states, it's already done.
18840 * src/output.c (output_actions): No longer free the shifts, then
18841 the reductions, then the states: free all the states and their
18844 2001-12-10 Akim Demaille <akim@epita.fr>
18846 * src/options.c (OPTN, DRTV, BOTH): New.
18847 (option_table): Use them.
18849 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
18850 the job of system.h.
18851 * src/options.c: Don't include stdio.h and xalloc.h for the same
18854 2001-12-10 Akim Demaille <akim@epita.fr>
18856 * src/output.c (output, prepare): Make sure the values of the
18857 muscles `action' and `prologue' are 0-terminated.
18859 2001-12-10 Akim Demaille <akim@epita.fr>
18861 Clean up GCC warnings.
18863 * src/reader.c (copy_action): `buf' is not used.
18864 (parse_skel_decl): Be static.
18865 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
18866 * src/options.h (create_long_option_table): Have a real prototype.
18867 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
18868 (hash_delete_at): Return const void *.
18869 Adjust casts to preserve the const.
18871 2001-12-10 Akim Demaille <akim@epita.fr>
18873 * configure.in: Require 2.52g.
18874 M4 is not needed, but AUTOM4TE is.
18875 * m4/m4.m4: Remove.
18876 * tests/Makefile.am: Adjust.
18878 2001-12-10 Akim Demaille <akim@epita.fr>
18880 One structure for states is enough, even though theoretically
18881 there are LR(0) states and LALR(1) states.
18883 * src/lalr.h (state_t): Remove.
18884 (state_table): Be state_t **, not state_t *.
18885 * src/state.h (core, CORE_ALLOC): Rename as...
18886 (state_t, STATE_ALLOC): this.
18887 Add the LALR(1) members: shifts, reductions, errs.
18888 * src/LR0.c (state_table): Rename as...
18889 (state_hash): this, to avoid name clashes with the global
18891 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
18892 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
18894 2001-12-10 Akim Demaille <akim@epita.fr>
18896 Bison dumps core on bash.y.
18897 Reported by Pascal Bart.
18899 * src/warshall.c (bitmatrix_print): New.
18901 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
18902 j must be the outer loop.
18903 * tests/regression.at (Broken Closure): New.
18905 2001-12-05 Akim Demaille <akim@epita.fr>
18907 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
18909 Reported by Peter Hamorsky.
18911 2001-12-05 Akim Demaille <akim@epita.fr>
18913 * src/conflicts.c (err_table): Remove.
18914 (resolve_sr_conflict): Adjust.
18915 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
18917 (state_t.reductions, state_t.shifts): this.
18919 2001-12-05 Akim Demaille <akim@epita.fr>
18921 * src/reduce.c (reduce_grammar_tables): No longer disable the
18922 removal of useless rules via CPP but via `if (0)', so that the
18923 compiler still check the code is valid.
18924 For instance, it should have noticed `rline' no longer exists: use
18925 the `line' member of rule_t.
18926 * src/gram.c (dummy, rline): Remove, unused.
18928 2001-12-05 Akim Demaille <akim@epita.fr>
18930 * src/output.c (pack_vector): Use assert, not berror.
18931 * src/main.c (berror): Remove, unused.
18933 2001-12-05 Akim Demaille <akim@epita.fr>
18935 New experimental feature: if --verbose --trace output all the
18936 items of a state, not only its kernel.
18938 * src/print.c (print_core): If `trace_flag', then invoke closure
18939 before outputting the items of the state (print_core is no longer
18940 a correct name them).
18941 (print_results): Invoke new_closure/free_closure if needed.
18943 2001-12-05 Akim Demaille <akim@epita.fr>
18945 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
18946 * src/closure.c, src/closure.h (itemsetsize): Rename as...
18947 (nitemset): for consistency with the rest of the project.
18949 2001-12-05 Akim Demaille <akim@epita.fr>
18951 * src/closure.c (print_closure): Improve.
18952 (closure): Use it for printing input and output.
18954 2001-12-05 Akim Demaille <akim@epita.fr>
18956 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
18957 indexed by nonterminals.
18959 2001-12-05 Akim Demaille <akim@epita.fr>
18961 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
18963 * src/warshall.h: Remove accidental duplication of the content.
18965 2001-12-05 Akim Demaille <akim@epita.fr>
18967 * src/closure.c (set_fderives): De-obfuscate.
18969 2001-12-05 Akim Demaille <akim@epita.fr>
18971 * src/closure.c (print_firsts, print_fderives): De-obfuscate.

18977 2001-12-05 Akim Demaille <akim@epita.fr>
18979 * src/output.c (action_row): De-obfuscate
18980 using the good o' techniques: arrays not pointers, variable
18981 locality, BITISSET, RESETBIT etc.
18983 2001-12-05 Akim Demaille <akim@epita.fr>
18985 Pessimize the code to simplify it: from now on, all the states
18986 have a valid SHIFTS, which NSHIFTS is possibly 0.
18988 * src/LR0.c (shifts_new): Be global and move to..
18989 * src/state.c, src/state.h: here.
18990 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
18991 * src/print_graph: Adjust.
18993 2001-12-05 Akim Demaille <akim@epita.fr>
18995 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
18996 * src/conflicts.c: Use it.
18997 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
18998 incorrectly ``simplified''.
19000 2001-12-05 Akim Demaille <akim@epita.fr>
19002 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
19003 using the good o' techniques: arrays not pointers, variable
19004 locality, BITISSET, RESETBIT etc.
19006 2001-12-05 Akim Demaille <akim@epita.fr>
19008 * src/state.h (SHIFT_SYMBOL): New.
19009 * src/conflicts.c: Use it to deobfuscate.
19011 2001-12-05 Akim Demaille <akim@epita.fr>
19013 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
19014 (print_reductions): De-obfuscate using the good o' techniques:
19015 arrays not pointers, variable locality, BITISSET.
19017 2001-12-05 Akim Demaille <akim@epita.fr>
19019 * src/conflicts.c (print_reductions): Arrays, not pointers.
19022 2001-12-05 Akim Demaille <akim@epita.fr>
19024 * src/conflicts.c (print_reductions): Pessimize, but clarify.
19026 2001-12-05 Akim Demaille <akim@epita.fr>
19028 * src/conflicts.c (print_reductions): Improve variable locality.
19030 2001-12-05 Akim Demaille <akim@epita.fr>
19032 * src/conflicts.c (print_reductions): Pessimize, but clarify.
19034 2001-12-05 Akim Demaille <akim@epita.fr>
19036 * src/conflicts.c (print_reductions): Improve variable locality.
19038 2001-12-05 Akim Demaille <akim@epita.fr>
19040 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
19041 * src/lalr.c: Use them.
19043 2001-12-05 Akim Demaille <akim@epita.fr>
19045 * src/LR0.c (augment_automaton): Formatting changes.
19046 Better variable locality.
19048 2001-12-05 Akim Demaille <akim@epita.fr>
19050 * src/lalr.c (matrix_print): New.
19051 (transpose): Use it.
19052 Use arrays instead of pointers.
19054 2001-12-05 Akim Demaille <akim@epita.fr>
19056 * src/lalr.c (maxrhs): Move to...
19057 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
19058 * src/lalr.c (build_relations): Adjust.
19060 2001-12-05 Akim Demaille <akim@epita.fr>
19062 * src/lalr.c (transpose): Free the memory allocated to the
19063 argument, as it is replaced by the results by the unique caller.
19064 (build_relations): Merely invoke transpose: it handles the memory
19066 Improve variable locality.
19067 Avoid variables used as mere abbreviations.
19068 (compute_lookaheads): Use arrays instead of pointers.
19070 2001-12-05 Akim Demaille <akim@epita.fr>
19072 * src/lalr.c (initialize_F): Improve variable locality.
19073 Avoid variables used as mere abbreviations.
19075 2001-12-05 Akim Demaille <akim@epita.fr>
19077 * src/derives.c (print_derives): Display the ruleno.
19078 * src/lalr.c (initialize_F, transpose): Better variable locality
19079 to improve readability.
19080 Avoid variables used as mere abbreviations.
19082 2001-12-05 Akim Demaille <akim@epita.fr>
19084 * src/lalr.c (traverse): Use arrays instead of pointers.
19086 2001-12-05 Akim Demaille <akim@epita.fr>
19088 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
19089 the handling of squeue.
19090 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
19092 2001-12-05 Akim Demaille <akim@epita.fr>
19094 Because useless nonterminals are now kept alive (instead of being
19095 `destroyed'), we now sometimes examine them, and store information
19096 related to them. Hence we need to know their number, and adjust
19097 memory allocations.
19099 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
19101 * src/LR0.c (allocate_itemsets): The memory allocated to
19102 `symbol_count' was used for two different purpose: once to count
19103 the number of occurrences of each symbol, and later reassigned to
19104 `shift_symbol', containing the symbol that can be shifted from a
19106 Deobfuscate, i.e., allocate, use and free `symbol_count' here
19108 (new_itemsets): Allocate `shift_symbol' here.
19109 (allocate_itemsets): symbol_count includes useless nonterminals.
19110 Make room for them.
19111 (free_storage): Use `free', not `XFREE', for pointers that cannot
19114 2001-12-05 Akim Demaille <akim@epita.fr>
19116 * src/nullable.c (set_nullable): Deobfuscate the handling of
19118 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
19120 2001-12-05 Akim Demaille <akim@epita.fr>
19122 * src/gram.c, src/gram.h (ritem_print): New.
19123 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
19124 (This useless function was defined only to work around VMS linkers
19125 that can't handle compilation units with variables only).
19126 * src/reduce.c (dump_grammar): Use it to trace the construction of
19129 2001-12-04 Paul Eggert <eggert@twinsun.com>
19131 * src/bison.simple (union yyalloc): Change member names
19132 to be the same as the stack names.
19133 (yyparse): yyptr is now union yyalloc *, not char *.
19134 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
19135 and may generate better code on some machines.
19136 (yystpcpy): Use prototype if __STDC__ is defined, not just
19137 if __cplusplus is defined.
19139 2001-11-30 Akim Demaille <akim@epita.fr>
19141 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
19142 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
19143 Gettext doesn't compile cleanly, and dies with -Werror.
19144 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
19145 Include WARNING_CFLAGS here.
19146 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
19147 before being defined.
19149 2001-11-27 Paul Eggert <eggert@twinsun.com>
19151 * lib/quotearg.h (quotearg_n, quotearg_n_style):
19152 First arg is int, not unsigned.
19153 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
19154 (SIZE_MAX, UINT_MAX): New macros.
19155 (quotearg_n_options): Abort if N is negative.
19156 Avoid overflow check on hosts where size_t is 64 bits and int
19157 is 32 bits, as overflow is impossible there.
19158 Fix off-by-one typo that caused unnecessary reallocation.
19160 2001-11-29 Paul Eggert <eggert@twinsun.com>
19162 Name space cleanup in generated parser.
19164 * doc/bison.texinfo (Bison Parser): Discuss system headers
19165 and their effect on the user name space.
19167 * src/bison.simple:
19168 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
19169 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
19170 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
19172 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing

19210 if body instead of `;' to pacify GCC's warnings.
19212 2001-11-30 Akim Demaille <akim@epita.fr>
19214 Instead of mapping the LHS of unused rules to -1, keep the LHS
19215 valid, but flag the rules as invalid.
19217 * src/gram.h (rule_t): `useful' is a new member.
19218 * src/print.c (print_grammar): Adjust.
19219 * src/derives.c (set_derives): Likewise.
19220 * src/reader.c (packgram, reduce_output): Likewise.

19253 an arbitrary restriction on hosts where size_t is wider than int.
19255 (yyparse): Don't dump core if alloca or malloc fails; instead, report

19257 three stacks, instead of allocating three blocks; this typically is
19258 faster and reduces fragmentation.
19260 Do not limit the number of items in the stack to a value that fits
19261 in 'int', as this is an arbitrary limit on hosts with 64-bit
19262 size_t and 32-bit int.

21126 introduces a guaranteed SEGV for semantic parsers.

21260 2000-11-17 Akim Demaille <akim@epita.fr>
21262 * lib/obstack.h: Formatting changes.
21263 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
21264 prevents type checking.
21265 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
21266 cast the value to (void *): assigning a `foo *' to a `void *'

21299 2000-11-07 Akim Demaille <akim@epita.fr>
21301 * src/reader.c (reader): #define YYLSP_NEEDED to 1 instead of just
21303 * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.

21325 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
21326 s/PFILE1/BISON_HAIRY/.
21327 Adjust dependencies.
21329 2000-11-03 Akim Demaille <akim@epita.fr>
21331 For some reason, this was not applied.
21333 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

21346 (done): Rename as...
21347 (output_files): this.
21348 Use `obstack_save'.
21349 * src/main.c (main): Don't use `atexit' to register `done', since
21350 it no longer has to remove tmp files, just call `output_files'
21351 when there are no errors.
21353 2000-11-02 Akim Demaille <akim@epita.fr>
21355 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

21357 * src/files.h: Formatting changes.
21359 2000-11-02 Akim Demaille <akim@epita.fr>
21361 Remove the last uses of mktemp and unlink/delete.
21363 * src/files.c (fdefines, ftable): Removed.

21423 * src/reader.c (copy_comment2): Expect the input stream to be on
21424 the `/' which is suspected to open a comment, instead of being
21425 called after `//' or `/*' was read.
21426 (copy_comment, copy_definition, parse_union_decl, copy_action)
21427 (copy_guard): Adjust.
21429 2000-10-16 Akim Demaille <akim@epita.fr>
21431 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

21455 2000-10-04 Akim Demaille <akim@epita.fr>
21457 When a literal string is used to define two different tokens,
21458 `bison -v' segfaults.
21459 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
21461 * tests/regression.m4: New file.
21462 Include the core of the sample provided by Piotr Gackiewicz.
21463 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
21466 2000-10-04 Akim Demaille <akim@epita.fr>
21468 * src/reader.c (parse_expect_decl): Keep `count' within the size
21472 2000-10-02 Paul Eggert <eggert@twinsun.com>

21483 2000-10-02 Akim Demaille <akim@epita.fr>
21485 * src/derives.c, src/print.c, src/reduce.c: To ease the
21486 translation, move some `\n' out of the translated strings.
21488 2000-10-02 Akim Demaille <akim@epita.fr>
21490 The location tracking mechanism is precious for parse error
21491 messages. Nevertheless, it is enabled only when `@n' is used in
21492 the grammar, which is a different issue (you can use it in error
21493 message, but not in the grammar per se). Therefore, there should
21494 be another means to enable it.
21496 * src/getargs.c (getargs): Support `--locations'.
21497 (usage): Report it.
21498 * src/getargs.h (locationsflag): Export it.
21499 * src/lex.c (percent_table): Support `%locations'.
21500 * src/reader.c (yylsp_needed): Remove this variable, now replaced
21501 with `locationsflag'.
21502 * doc/bison.texinfo: Document `--locations' and `%locations'.
21504 * tests/calc.m4: Test it.
21506 For regularity of the names, replace each
21507 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
21508 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
21509 In addition replace each `flag' with `_flag'.
21511 2000-10-02 Akim Demaille <akim@epita.fr>
21513 Also test parse error messages, including with YYERROR_VERBOSE.
21515 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
21517 Use it to check the computations.
21518 Use it to check `nonassoc' is honored.
21519 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
21520 `--yyerror-verbose'.
21521 (_AT_CHECK_CALC): Adjust to this option.

21524 2000-10-02 Akim Demaille <akim@epita.fr>
21526 Test also `--verbose', `--defines' and `--name-prefix'. Testing
21527 the latter demonstrates a flaw in the handling of non debugging
21528 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
21529 was used in order to simplify:
21545 unfortunately this leads to a CPP conflict when
21546 `--name-prefix=foo' is used since it produces `#define yydebug
21549 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
21550 (YYDPRINTF): New macro.
21552 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
21554 Also test `--verbose', `--defines' and `--name-prefix'.

21558 Improve the readability of the produced parsers.
21560 * src/bison.s1: Formatting changes.
21561 Improve the comment related to the `$' mark.
21562 (yydefault): Don't fall through to `yyresume': `goto' there.
21563 * src/output.c (output_parser): When the `$' is met, skip the end
21565 New variable, `number_of_dollar_signs', to check there's exactly
21566 one `$' in the parser skeleton.
21568 2000-10-02 Akim Demaille <akim@epita.fr>
21570 * lib/xstrdup.c: New file, from the fileutils.
21571 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
21572 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
21573 instead of strlen + xmalloc + strcpy.
21574 * src/symtab.c (copys): Remove, use xstrdup instead.
21576 2000-10-02 Akim Demaille <akim@epita.fr>
21578 * src/gram.h (associativity): New enum type which replaces the
21579 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
21580 `right_assoc', `left_assoc' and `non_assoc'.
21581 Adjust all dependencies.
21582 * src/reader.c: Formatting changes.
21583 (LTYPESTR): Don't define it, use it as a literal in
21584 `reader_output_yylsp'.
21585 * src/symtab.h (symbol_class): New enum type which replaces the
21586 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
21587 `sunknown', `stoken and `snterm'.
21589 2000-10-02 Akim Demaille <akim@epita.fr>
21591 * src/getargs.c (fixed_outfiles): Rename as...
21592 (yaccflag): for consistency and accuracy.
21593 Adjust dependencies.
21595 2000-10-02 Akim Demaille <akim@epita.fr>
21597 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
21598 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
21599 difficult and introduced a lot of core dump. It turns out that
21600 Bison used an implementation of `xmalloc' based on `calloc', and
21601 at various places it does depend upon the initialization to 0. I
21602 have not tried to isolate the pertinent places, and all the former
21603 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
21604 someone should address this issue.
21606 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
21607 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

21617 * src/system.h: Include `assert.h'.
21619 2000-10-02 Akim Demaille <akim@epita.fr>
21621 * src/state.h (nstates, final_state, first_state, first_shift)
21622 (first_reduction): Move their exportation from here...

21624 Adjust dependencies.
21625 * src/getargs.c (statisticsflag): New variable.
21626 Add support for `--statistics'.

21629 Remove a lot of now useless `extern' statements in most files.
21631 2000-10-02 Akim Demaille <akim@epita.fr>
21633 * src/LR0.h: New file.
21636 2000-10-02 Akim Demaille <akim@epita.fr>

21663 Propagate its inclusion.
21664 * src/reduce.c: Topological sort and other formatting changes.
21665 (bool, TRUE, FALSE): Move their definition to...

21670 * src/files.c: Formatting changes.
21671 (tryopen, tryclose, openfiles): Rename as...
21672 (xfopen, xfclose, open_files): this.
21673 (stringappend): static.
21674 * src/files.h: Complete the list of exported symbols.

21697 * src/lalr.c: Formatting changes, topological sorting etc.
21699 2000-10-02 Akim Demaille <akim@epita.fr>
21701 * src/output.c (token_actions): Introduce a temporary array,
21702 YYDEFACT, that makes it possible for this function to use
21703 output_short_table.
21705 2000-10-02 Akim Demaille <akim@epita.fr>
21707 `user_toknums' is output as a `short[]' in `output.c', while it is
21708 defined as a `int[]' in `reader.c'. For consistency with the
21709 other output tables, `user_toknums' is now defined as a table of

21753 * src/system.h: Define PARAMS.
21754 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
21755 purpose of config.h. system.h must not try to fix wrong
21756 definitions in config.h.

22740 (parse_percent_token): Added % declarations as another
22741 way to specify the flags -n, -l, and -r. Also added hooks for
22742 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
22743 major changes to files.c.
22744 (lex) Retain in the incoming stream a character following
