3 Remove src/Makefile.am.
4 * src/Makefile.am: Rename as...
5 * src/local.mk: this.
6 Prefix all the paths with src/.
7 (AUTOMAKE_OPTIONS): Build object files in the sub dirs.
8 (AM_CPPFLAGS): Find find in builddir/src.
9 (YACC): Move the flags into...
10 (AM_YFLAGS): here.
11 * maint.mk (sc_tight_scope): Disable.
12 It used to bounce to the version in src/Makefile.am which is now
13 part of this very Makefile.
14 * Makefile.am, configure.ac: Adjust.
15 * src/scan-code-c.c, src/scan-code.l: We can no longer rely on
16 include "..." to find files "here": we are no longer in src/, so
17 qualify the includes with src/.
18 * doc/Makefile.am (PREPATH): No longer include the top_builddir
19 prefix.
20 (.x.1): Adjust to be able to create src/foo from the top level
21 Makefile, instead of going bounce to src/Makefile the creation of
22 foo.

48 examples/calc++/Makefile.am might be interesting to keep as is, since
49 it is an example in itself.

76
77 Instead of using make_symbol<TOK_FOO>, generate make_FOO for each token type.
78 Using template buys us nothing, and makes it uselessly complex to
79 construct a symbol. Besides, it could not be generalized to other
80 languages, while make_FOO would work in C/Java etc.
81
82 * data/lalr1.cc (b4_symbol_): New.
83 (b4_symbol): Use it.
84 (b4_symbol_constructor_declaration_)
85 (b4_symbol_constructor_definition_): Instead of generating
86 specializations of an overloaded template function, just generate
87 several functions whose names are forged from the token names
88 without the token.prefix.
89 (b4_symbol_constructor_declarations): Generate them for all the
90 symbols, not just by class of symbol type, now that instead of
91 specializing a function template by the token, we generate a
92 function named after the token.
93 (b4_symbol_constructor_specialization_)
94 (b4_symbol_constructor_specializations): Remove.
95 * etc/bench.pl.in: Adjust to this new API.

98
99 %define token.prefix.
100 Provide a means to add a prefix to the name of the tokens as output in the
101 generated files. Because of name clashes, it is good to have such a
102 prefix such as TOK_ that protects from names such as EOF, FILE etc.
103 But it clutters the grammar itself.
104
105 * data/bison.m4 (token.prefix): Empty by default.
106 * data/c.m4 (b4_token_enum, b4_token_define): Use it.
107 * data/lalr1.cc (b4_symbol): Ditto.

117 symbol::token.
118 This is allows the user to get the type of a token return by
119 yylex.
120
121 * data/lalr1.cc (symbol::token): New.
122 (yytoknum_): Define when %define lex_symbol, independently of
123 %debug.
124 (yytoken_number_): Move into...
125 (symbol::token): here, since that's the only use.
126 The other one is YYPRINT which was not officially supported
127 by lalr1.cc, and anyway it did not work since YYPRINT uses this
128 array under a different name (yytoknum).

147
148 Define make_symbol in the header.
149 To reach good performances these functions should be inlined (yet this is
150 to measure precisely). To this end they must be available to the caller.
151
152 * data/lalr1.cc (b4_symbol_constructor_definition_): Qualify
153 location_type with the class name.
154 Since will now be output in the header, declare "inline".
155 No longer use b4_symbol_constructor_specializations, but
156 b4_symbol_constructor_definitions in the header.
157 Don't call it in the *.cc file.

162 * data/lalr1.cc: Move the invocation of b4_yytranslate_definition
163 into the header file when using %define lex_symbol.
164 (yytranslate_): Declare inline.

167
168 Define the constructors of symbol_type in b4_symbol_constructor_definitions.
169 The constructors are called by the make_symbol functions, which a
170 forthcoming patch will move elsewhere. Hence the interest of putting them
171 together.
172
173 The stack_symbol_type does not need to be moved, it is used only by the
174 parser.
175
176 * data/lalr1.cc: Move symbol_type and symbol_base_type
177 constructors into...
178 (b4_symbol_constructor_definitions): here.
179 Adjust.

183 Make it easier to move the definition of yytranslate_.
184 Forthcoming changes will make it possible to use yytranslate_
185 from outside the parser implementation file.

188 Use it.

192 Remove useless class specification.
193 * data/lalr1.cc (b4_symbol_constructor_specialization_): No need
194 to refer to the class name to use a type defined by the class for
195 arguments of member functions.

198
199 Finer input type for yytranslate.
200 This patch is debatable: the tradition expects yylex to return an int
201 which happens to correspond to token_number (which is an enum). This
202 allows for instance to return characters (such as '*' etc.). But this
203 goes against the stronger typing I am trying to have with the new
204 lex interface which return a symbol_type. So in this case, feed
205 yytranslate_ with a token_type.
206
207 * data/lalr1.cc (yytranslate_): When in %define lex-symbol,
208 expect a token_type.

219 attributes type_name and has_type_name as type and has_type.

224 Use b4_type_names for the union type.
225 The union used to compute the size of the variant used to iterate over the
226 type of all the symbols, with a lot of redundancy. Now iterate over the
227 lists of symbols having the same type-name.
228
229 * data/lalr1.cc (b4_char_sizeof_): New.
230 (b4_char_sizeof): Use it.
231 Adjust to be called with a list of numbers instead of a single
232 number.
233 Adjust its caller for new-line issues.

236
237 Define the "identifier" of a symbol.
238 Symbols may have several string representations, for instance if they
239 have an alias. What I call its "id" is a string that can be used as
240 an identifier. May not exist.
241
242 Currently the symbols which have the "tag_is_id" flag set are those that
243 don't have an alias. Look harder for the id.
244
245 * src/output.c (is_identifier): Move to...
246 * src/symtab.c (is_identifier): here.
247 * src/symtab.h, src/symtab.c (symbol_id_get): New.
248 * src/output.c (symbol_definitions_output): Use it to define "id"
249 and "has_id".
250 Remove the definition of "tag_is_id".
251 * data/lalr1.cc: Use the "id" and "has_id" whereever "tag" and
252 "tag_is_id" were used to produce code.
253 We still use "tag" for documentation.

382 Introduce make_symbol.
383 make_symbol provides a means to construct a full symbol (kind, value,
384 location) in a single shot. It is meant to be a Symbol constructor,
385 parameterized by the symbol kind so that overloading would prevent
386 incorrect kind/value pairs. Unfortunately parameterized constructors do
387 not work well in C++ (unless the parameter also appears as an argument,
388 which is not acceptable), hence the use of a function instead of a
389 constructor.

399 overloaded function "make_symbol".
400 (variant::variant): Always define a default ctor.
401 Also provide a copy ctor.
402 (symbol_base_type, symbol_type): New ctor overloads for value-less

416 Test 214 was failing: it greps with a pattern containing [ ]*
417 which obviously meant to catch spaces and tabs, but contained only
418 spaces. Tabulations in sources are a nuisance, so to simplify the
419 matter, get rid of all the tabulations in the Java sources. The
420 other skeletons will be treated equally later.
421

604 Change the handling of the symbols in the skeletons.
605 Before we were using tables which lines were the symbols and which
606 columns were things like number, tag, type-name etc. It is was
607 difficult to extend: each time a column was added, all the numbers had
608 to be updated (you asked for colon $2, not for "tag"). Also, it was
609 hard to filter these tables when only a subset of the symbols (say the
610 tokens, or the nterms, or the tokens that have and external number
611 *and* a type-name) was of interest.
de62edee 612
d69c9694
AD
613 Now instead of monolithic tables, we define one macro per cell. For
614 instance "b4_symbol(0, tag)" is a macro name which contents is
615 self-decriptive. The macro "b4_symbol" provides easier access to
616 these cells.

933 Add "%define assert" to variants.
934 This is used to help the user catch cases where some value gets
935 ovewritten by a new one. This should not happen, as this will
936 probably leak.

938 Unfortunately this uncovered a bug in the C++ parser itself: the
939 lookahead value was not destroyed between two calls to yylex. For
940 instance if the previous lookahead was a std::string, and then an int,
941 then the value of the std::string was correctly taken (i.e., the
942 lookahead was now an empty string), but std::string structure itself
943 was not reclaimed.
de62edee 944
2d32fc9f
AD
945 This is now done in variant::build(other&) (which is used to take the
946 value of the lookahead): other is not only stolen from its value, it
947 is also destroyed. This incurs a new performance penalty of a few
948 percent, and union becomes faster again.

1229 Fuse the three stacks into a single one.
1230 In order to make it easy to perform benchmarks to ensure that there are no
1231 performance loss, lalr1.cc is forked into lalr1-fusion.cc. Eventually,
1232 lalr1-fusion.cc will replace lalr1.cc.
de62edee 1233
0e0ed236
AD
1234 Meanwhile, to make sure that lalr1-fusion.cc is correctly exercized by the
1235 test suite, the user must install a symbolic link from lalr1.cc to it.

1237 Instead of having three stacks (state, value, location), use a stack
1238 of triples. This considerably simplifies the code (and it will be
1239 easier not to require locations as currently does the C++ parser),
1240 and also gives a 10% speedup according to etc/bench (probably mainly since
1241 memory allocation is done once instead of three times).
de62edee 1242
0e0ed236

1243 Another motivation is to make it easier to destruct properly
1244 semantic values: now that they are bound to their state (hence
1245 symbol type) it will be easier to call the appropriate destructor.

1292 Use variants to support objects as semantic values.
1293 This patch was inspired by work by Michiel De Wilde. But he used Boost
1294 variants which (i) requires Boost on the user side, (ii) is slow, and
1295 (iii) has useless overhead (the parser knows the type of the semantic value
1296 there is no reason to duplicate this information as Boost.Variants do).

2538 * data/c++.m4: (b4_namespace_ref, b4_namespace_open,
2539 b4_namespace_close): New macros that interpret the %define variable
2540 "namespace" so its value can contain "::" to indicate nested
2541 namespaces.
2542 * data/glr.cc (b4_namespace): Don't define, and replace all uses with
2543 the above macros.
2544 * data/lalr1.cc (b4_namespace): Likewise.
2545 * data/location.cc (b4_namespace): Likewise.
2546 * doc/bison.texinfo (Decl Summary): Move `%define push_pull' entry
2547 inside a new table in the general %define entry. Document `%define
2548 namespace' there as well. Point the %name-prefix entry to it since it
2549 explains it more completely in the case of C++.
2550 (C++ Bison Interface): Mention `%define namespace' instead of
2551 %name-prefix.
2552 (Table of Symbols): Remove the `%define push_pull' entry. The %define
2553 entry suffices.
2554 * tests/c++.at (Relative namespace references): New test case.
2555 (Absolute namespace references): New test case.
2556 (Syntactically invalid namespace references): New test case.
2557 * tests/input.at (C++ namespace reference errors): New test case.

2595 to stdout so they don't become arguments to other macros. Update
2596 comments and add examples.
2597 (b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and
2598 add examples.
2599 (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately
2600 after printing the error directive so that M4 doesn't report subsequent
2601 problems that are induced by this problem.
2602 * src/scan-skel.l: Recognize @` digraph outside of directive arguments
2603 instead of just in them. Recognize @\n in both places. Both expand to
2604 the empty string. Needed by b4_cat.

2997 * src/lalr.c (state_lookahead_tokens_count): For code readability,
2998 move the check for disabled transitions to an aver since conflict
2999 resolution hasn't happened yet.
3000
3001 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
3002 labels a state as inconsistent just because it has error transitions.
3003 The original form of this check appeared in revision 1.1 of lalr.c,
3004 which was committed on 1991-12-21. Now (at least), changing the
3005 consistency label on such a state appears to have no useful effect in
3006 any of the places it is examined, which I enumerate below. The key
3007 point to understanding each item in this enumeration is that a state
3008 with an error transition is labelled consistent in the first place only
3009 if it has no rules, so the check cannot matter for states that have
3010 rules. (1) Labelling a state as inconsistent will cause set_conflicts
3011 to try to identify its conflicts, and a state must have *rules* to have
3012 conflicts. (2) Labelling a state as inconsistent will affect how
3013 action_row sets the default *rule* for the state. (3) Labelling a
3014 state as inconsistent will cause build_relations to add lookback edges
3015 to *rules* in that state.
3016 * src/state.h (struct state): Word the comment for member consistent
3017 more carefully.

3326 strcasecmp has "unspecified behavior" outside the POSIX locale,

3655 Instead of having skeletons declare all valid %define variables and

3657 and build these lists automatically. Thus Bison will now warn when a
3658 variable or qualifier is not used by the skeleton in the current
3659 invocation regardless of whether it might sometimes be used by that
3660 skeleton in other invocations. Also, move all %define value macros to
3661 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
3662 form, which is replaced by %code.

4048 generate yypull_parse or yyparse unless %push-pull-parser is declared.
4049 Discussed starting at
4050 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
4051 * data/bison.m4 (b4_pull_if): New.
4052 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
4053 * data/push.c: Improve M4 quoting a little.
4054 (b4_generate_macro_args, b4_parenthesize): Remove.
4055 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
4056 any time a pull parser is requested.
4057 Don't #define this as a wrapper around yypull_parse. Instead, when
4058 both push and pull are requested, make it a function that does that
4059 same thing.
4060 (yypull_parse): If there's a b4_prefix, #define this to
4061 b4_prefix[pull_parse] when both push and pull are requested.
4062 Don't define this as a function unless both push and pull are
4063 requested.
4064 Remove the yylexp argument and hard-code yylex invocation instead.
4065 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
4066 %push-parser.
4067 * src/getargs.c (pull_parser): New global initialized to true.
4068 * getargs.h (pull_parser): extern it.
4069 * src/output.c (prepare): Insert pull_flag muscle.
4070 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
4071 (prologue_declaration): Set both push_parser and pull_parser = true for
4072 %push-pull-parser. Set push_parser = true and pull_parser = false for
4073 %push-parser.
4074 * src/scan-gram.l: Don't accept %push_parser as an alternative to
4075 %push-parser since there's no backward-compatibility concern here.
4076 Scan %push-pull-parser.
4077 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
4078 instead of %push-parser.
4079 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
4080 prototype it in the module that calls yyparse.
4081 * tests/input.at (Torturing the Scanner): Likewise.
4082 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.

4086 Update etc/bench.pl. Optimize push mode a little (the yyn change
4087 deserves most of the credit).
4088 * Makefile.am (SUBDIRS): Add etc subdirectory.
4089 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
4090 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
4091 yytoken, yyval, and yyloc declarations to...
4092 (yyparse or yypush_parse): ... here to improve performance. For
4093 yypush_parse invocations after the first, be sure to assign yyn its old
4094 value again.
4095 (yypstate_new): Don't bother initializing the yyresult field since the
4096 initial value isn't used.
4097 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
4098 remove the #define that, in push mode, set it to yyps->NAME.
4099 * etc/Makefile.am: New.
4100 * etc/bench.pl: Remove and build it instead from...
4101 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
4102 "tests/bison" from the build directory by default rather than just
4103 invoking "bison" from $PATH.
4104 (calc_grammar): Update push parser code: don't declare yylval globally,
4105 don't define yyparse_wrapper, and don't #define yyparse.
4106 (bench_grammar): Update to check all working combinations of yacc.c,
4107 push.c, impure, pure, pull, and push.

4113 (yypull_parse): New function wrapping yypush_parse.
4114 (yyparse): New #define wrapping yypull_parse.
4115 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
4116 is declared.
4117 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
4118 prototype yylex in the module that calls yyparse, and don't prototype
4119 yyparse there. Otherwise, the yyparse expansion won't compile.
4120 * tests/input.at (Torturing the Scanner): Likewise.

4124 Enable push parsers to operate in impure mode. Thus, %push-parser no
4125 longer implies %pure-parser. The point of this change is to move
4126 towards being able to test the push parser code by running the entire
4127 test suite as if %push-parser had been declared.
4128 * data/push.c (yypush_parse): For impure mode, remove the
4129 yypushed_char, yypushed_val, and yypushed_loc arguments.
4130 Instead, declare these as local variables initialized to the global
4131 yychar, yylval, and yylloc.
4132 For the first yypush_parse invocation only, restore the initial values
4133 of these global variables when it's time to read a token since they
4134 have been overwritten.
4135 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
4136 %push-parser.
4137 * tests/calc.at (Simple LALR(1) Calculator): Always declare
4138 %pure-parser along with %push-parser since this test case was designed
4139 for pure push parsers.
4140 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
4141 (AT_YACC_OR_PUSH_IF): New.
4142 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
4143 add a note that it's still wrong for some cases (as it has been for a
4144 while).
4145 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
4146 %push-parser no longer implies %pure-parser.

4167 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
4168 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
4169 more closely mimic the pull parser logic.
4170 Don't copy the pushed token to yychar, yylval, and yylloc until it's
4171 time to read a token, which is after any initialization of yylval and
4172 yylloc.

4179 Rearrange initialization of the parser state variables so that the
4180 skeleton doesn't have to have a copy for pull mode and another for push
4181 mode. This patch also fixes at least a bug such that yylloc was not
4182 initialized (with b4_location_initial_line and
4183 b4_location_initial_column) upon calling yypush_parse. However, that
4184 initialization now overwrites the first token's location;
4185 %initial-action assigning @$ already did the same thing, and both bugs
4186 will be fixed in a later patch.
4187 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
4188 (b4_declare_parser_state_variables): Remove initialization of yytoken,
4189 yyss, yyvs, yyls, and yystacksize.
4190 (yypstate_new): Remove initialization of some yypstate fields: yystate,
4191 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
4192 yylsp.
4193 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
4194 yyps->NAME so it can be used in yypush_parse.
4195 (yyparse or yypush_parse): For yypush_parse, don't print the
4196 "Starting parse" diagnostic for invocations after the first.
4197 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
4198 yypush_parse, only do it for the first invocation.
4199 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
4200 initialization to occur in yypush_parse but only on the first

4214 Encapsulate the push parser state variables into an M4 macro so the
4215 push skeleton doesn't have to list them again for pull mode's yyparse.
4216 For push mode, remove yypush_parse's local equivalents of these
4217 variables to eliminate unnecessary copying between the two sets at
4218 run-time. This patch also fixes at least a bug related to multiple
4219 %initial-action invocations in push mode.

4223 (b4_declare_yyparse_variables): Remove and move its contents to the one
4224 spot where it was invoked.

4226 state variables required by push mode.
4227 (struct yypstate): Replace all fields but yynew with

4229 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
4230 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
4231 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
4232 (yyparse or yypush_parse): For yyparse in pull mode, replace local
4233 parser state variable declarations with
4234 b4_declare_parser_state_variables.
4235 Don't initialize parser state variables when calling yypush_parse since
4236 yypstate_new already does that.
4237 Invoke the user's initial action only upon the first yypush_parse
4238 invocation.

4240 and the yypstate.

5129 * src/scan-code.l: Always initialize braces_level; the old code
5130 left it uninitialized and therefore had undefined behavior.

5133 systems where standard headers (mistakenly) include <assert.h>.

5287 Whether the default %destructor/%printer applies to a particular symbol
5288 isn't a question of whether the user *declares* that symbol (in %token,
5289 for example). It's a question of whether the user by any means
5290 *defines* the symbol at all (by simply using a char token, for
5291 example). $end is defined by Bison whereas any other token with token
5292 number 0 is defined by the user. The error token is always defined by
5293 Bison regardless of whether the user declares it with %token, but we
5294 may one day let the user define error as a nonterminal instead.
5295 * NEWS (2.3+): Say "user-defined" instead of "user-declared".

5698 by mbswidth) needs the latter.
5699 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to

5808 haven't been translated yet.
5809 Record the midrule's parent rule and its RHS index within the parent
5810 rule.

5812 since not all symbol declarations may have been parsed yet and, thus,
5813 warnings about types for $$, $n, @$, and @n can't be reported yet.
5814 (packgram): Translate the action and invoke grammar_rule_check now that
5815 all symbol declarations have been parsed.
5816 * src/scan-code.l (handle_action_dollar): Now that this is invoked
5817 after parsing the entire grammar file, the symbol list here in the case
5818 of a midrule is actually the midrule's empty RHS, so reference its
5819 parent rule's RHS where necessary.
5820 On the other hand, now that you can already know it's a midrule, you

5828 terminates a rule. symbol_list_print already does this correctly.
5829 * src/symlist.h (symbol_list.midrule_parent_rule,

6028 The Translation Project changed its way of publishing translations
6029 to maintainers. I haven't received any responses to my request
6030 for supporting the old way, or for documenting the new way. I
6031 have modified 'bootstrap' to use screen scraping
6032 (in this case, HTML scraping). This is unreliable and inelegant,
6033 but I don't see any better way. Yuck.
6034 * bootstrap (TP_URL, WGET_COMMAND): New vars.
6035 (get_translations): New function, which uses HTML scraping to
6036 deduce locations of latest translations.
6037 Use this function to grab both bison and bison-runtime .po files.
6038 Don't bother priming the pump for the runtime-po domain any more,
6039 as it's now translated better than bison is.

6351 fixes the remaining bug reported by Derek M. Jones in
6352 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
6353 * tests/glr-regression.at (Uninitialized location when reporting
6354 ambiguity): Test the above case.
6355 Also, the embedded comments in this test case claim it checks the case
6356 of an empty RHS that has inherited the initial location. However, the
6357 corresponding LHS was already resolved, so yyresolveLocations didn't
6358 actually have reason to modify it. Fix this by forcing
6359 nondeterministic operation at the beginning of the parse.

6747 More portability fixes for problems summarized by Nelson H. F. Beebe.

6760 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
6761 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
6762 "warning: sorry: semantics of inline function static data `const
6763 unsigned char translate_table[262]' are wrong (you'll wind up with
6764 multiple copies)".

6766 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
6767 or, xor to not_, and_, or_, and xor_, respectively. This works
6768 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
6769 random system header somewhere that includes the equivalent of
6770 <iso646.h>.

6778 During deterministic GLR operation, user actions should be able to
6779 influence the parse by changing yychar. To make this easier to fix and
6780 to make glr.c easier to evolve in general, don't maintain yytoken in
6781 parallel with yychar; just compute yytoken when needed.
6782 * tests/glr-regression.at (Incorrect lookahead during deterministic
6783 GLR): Check that setting yychar in a user action has the intended
6784 effect.
6785 * data/glr.c (yyGLRStack): Remove yytokenp member.
6786 (yyclearin): Don't set *yytokenp.
6787 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
6788 yychar rather than *yytokenp to determine the current lookahead.
6789 Compute yytoken locally when needed.
6790 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
6791 point to.
6792
6793 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
6794 after `--report' documentation.

6808 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
6809 got from <http://bro-ids.org/download.html>. The bug is that
6810 when two actions appeared in succession, the second one was
6811 scanned before the first one was added to the grammar rule
6812 as a midrule action. Bison then output the incorrect warning
6813 "parse.y:905.17-906.36: warning: unused value: $3".
6814 * src/parse-gram.y (BRACED_CODE, action): These are no longer
6815 associated with a value.
6816 (rhs): Don't invoke grammar_current_rule_action_append.
6817 (action): Invoke it here instead.
6818 * src/reader.c (grammar_midrule_action): Now extern.
6819 (grammar_current_rule_action_append): Don't invoke
6820 grammar_midrule_action; that is now the scanner's job.
6821 * src/reader.h (last_string, last_braced_code_loc):
6822 (grammar_midrule_action): New decls.
6823 * src/scan-gram.l (last_string): Now extern, sigh.
6824 (last_braced_code_loc): New extern variable.
6825 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
6826 rule already has an action.
6827 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
6828 * tests/input.at (AT_CHECK_UNUSED_VALUES):
6829 Add some tests to check that the above changes fixed the bug.

6835 not whether it is typed.

6854 user can override the types.
6855 (short): #undef, to work around a bug in Pike 7.0.
6856 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.

6876 visible elsewhere.

7142 * data/glr.c (yyresolveValue): When merging semantic options, if at
7143 least one user action succeeds but a later one cuts the parse, then
7144 destroy the semantic value before returning rather than leaking it.
7145 (yyresolveStates): If a user action cuts the parse and thus
7146 yyresolveValue fails, ignore the (unset) semantic value rather than
7147 corrupting the yyGLRState, and empty the semantic options list since
7148 the user actions should have called all necessary destructors.
7149 Simplify code with YYCHK.

8384 "make maintainer-distcheck" complained about.

8387 and omit line-number decoration that makes Emacs compile think
8388 that informative messages are worth worrying about.

8408

8413 the new runtime-po domain, prime the pump by extracting the
8414 relevant strings from the obsolete translations. This code can be
8415 removed once the bison-runtime domain has been translated by each
8416 team.

8442 * doc/bison.texinfo (Decl Summary, Calling Convention):
8443 Clarify quoting convention of yytname.
8444 * src/output.c (prepare_symbols): Quote all names. This undoes
8445 the 2005-04-17 change, which is now accomplished (mostly) via
8446 changes in the parsers as described above.
8447 * tests/regression.at (Token definitions, Web2c Actions):
8448 Undo most 2005-04-17 change here, too.

8452 Fix more problems reported by twlevo@xs4all.nl.
8453 * tests/cxx-type.at: Don't pipe output of ./types through sed to
8454 remove trailing spaces. This loses the exit status of ./types,
8455 and isn't needed since ./types shouldn't be emitting trailing
8456 spaces.
8457 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
8458 as the stack isn't valid in that case.
8459
8460 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
8461 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
8462 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):

8464 is used.

8470 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
8471 overly-picky compilers that reject 'char *foo = "bar";'.
8472
8473 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
8474 to FILE * parameter, not to stderr. This fixes a typo introduced
8475 in the 2005-07-12 change.
8476
8477 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
8478 warnings from GCC 4.

8489 Destructor cleanups and regularization among the three skeletons.
8490 * NEWS: Document the behavior changes.
8491 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
8492 stack before failing, as the cleanup code will do it for us now.
8493 * data/lalr1.cc (yyerrlab): Likewise.
8494 * data/glr.c (yyparse): Pop everything off the stack before
8495 freeing it, so that destructors get called properly.
8496 * data/lalr1.cc (yyreturn): Likewise.
8497 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
8498 This is more consistent.
8499 * doc/bison.texinfo (Destructor Decl): Mention more reasons
8500 why destructors might be called. 1.875 -> 2.1.

8502 Some English-language cleanups for %destructor.
8503 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

8515 Rename yyoverflowab to yyexhaustedlab.
8516 When memory exhaustion occurs during syntax-error reporting,
8517 report it separately rather than in a single diagnostic; this
8518 eases translation.

8520 (Memory Exhausted): Renamed from Parser Stack Overflow.

8526 Add i18n support to the GLR skeleton. Partially fix the C++
8527 skeleton; a C++ expert needs to finish this. Remove debugging
8528 msgids; there's little point to having them translated, since they
8529 can be understood only by someone who can read the
8530 (English-language) source code.
8531
8532 Generate runtime-po/bison-runtime.pot automatically, so that we
8533 don't have to worry about garbage getting in that file. We'll
8534 make sure after the next official release that old msgids don't
8535 get lost. See
8536 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
8537
8538 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
8539 Now auto-generated.
8540 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
8541 Fix typos in explanations of the runtime file.
8542 * bootstrap: Change gettext keyword from YYI18N to YY_.
8543 Use standard Makefile.in.in in runtime-po, since we'll arrange
8544 for backward-compatible bison-runtime.po files in a different way.
8545 * data/glr.c (YY_): New macro, from yacc.c.
8546 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
8547 Translate messages intended for users.
8548 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
8549 the wording in the other skeletons. We don't know that the memory
8550 is virtual.
8551 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
8552 Use same method that yacc.c uses.
8553 Don't translate debugging messages.
8554 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
8555 it doesn't work (yet), and requires C++ expertise to fix.
8556 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
8557 Move defn to a more logical place, to be consistent with other
8558 skeletons.
8559 Don't translate debugging messages.
8560 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
8561 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
8562 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
8563 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.

8579 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
8580 (yyparse): New local variable yyresult to record the result.

8586 if YYABORT is used).

8797 than vsprintf. Allocate a bigger buffer if possible.

8800 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
8801 the initialization was successful. It might fail if storage was
8802 exhausted.

9767 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
9768 whether the reducion was empty or not. This leaves room to
9769 improve the use of YYLLOC_DEFAULT in such a case.
9770 lalr1.cc is still experimental, so changing this is acceptable.
9771 And finally, there are probably not many users who changed the
9772 handling of locations in GLR, so changing is admissible too.

9917 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
9918 Bison directive from the Bison file to the invocation of this
9919 macro, so that these directives are passed to
9920 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
9921 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
9922 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
9923 the extra Bison directives instead of the whole series.
9924 Change the grammar so that there are recoverable errors, and
9925 unrecoverable errors. Now we can have the parser give up before
9926 consuming the whole input. As a result we now can observe that
9927 the lookahead is freed when needed.
9928 Change the parser source to parse argv[1] instead of a hard coded
9929 string.
9930 Simplify yylex, and give a value and location to EOF.
9931 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
9932 passed directives already coded in the file.
9933 Add some tests to check the location of "error".
9934 For some tests, the C++ parser is correct, and not yacc.c.
9935 For other tests, they provide different, but unsatisfying, values,
9936 so keep the C++ value so that at least one parser is "correct"
9937 according to the test suite.
9938 (Actions after errors): Remove, this is subsumed by the
9939 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

10120 a seemingly endless set of combinations of versions more recent
10121 than that. The bottom line is that the current sources require
10122 fairly recent versions of the build tools, and it'll be some work

10255 Get files from the gnulib and po repositories, instead of relying
10256 on them being in our CVS. Upgrade to latest versions of gnulib
10257 and Automake.
10258
10259 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
10260 * bootstrap: Bootstrap from gnulib and po repositories.
10261 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
10262 * README-cvs: Document these changes. Remove version numbers from
10263 mentions of build tools, since they change so often. Mention Flex.
10264
10265 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.

12ffdd28
PE
10267 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):

1f65350a 10269 does this for us.
12ffdd28
PE
10270 (AC_ISC_POSIX): Remove; we no longer support this
10271 ancient OS, as it gets in the way of latest Autoconf & gnulib.

10272 (AC_HEADER_STDC): Remove: we now assume C89 or better.
10273 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
10274 Do not check for C89 headers, except for locale.h which is used
10275 by the Yacc library and must port to K&R hosts.
10276 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
10277 Do not check for C89 functions, except for setlocale which is
10278 used by the Yacc library.

10284 AM_GNU_GETTEXT): Remove; now done by:
10285 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
10286 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
10287 for us.
10288
10289 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
10290 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
10291 Define to empty, as gnulib.mk will do the rest for us.
10292 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
10293 for us.
10294 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
10295 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
10296
10297 * src/files.c: Include gnulib's xstrndup.h.
10298
10299 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
10300 (REALLOC): Use xnrealloc, for likewise.
10301 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.

10327 by bootstrap or automake.
10328
10329 * po/ChangeLog: Remove: all but one entry was a duplicate
10330 of this file, and I moved that 2000-11-02 entry here.

10356
10357 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
10358 case, as stos_ is now used by destructors due to the 2004-02-09
10359 change.
10360
10361 Remove more K&R C support.
10362 * lib/libiberty.y (PARAMS): Remove. All uses removed.

10374 * tests/conflicts.at (%nonassoc and eof): Include stdlib.h
10375 unconditionally.

10377 * src/complain.c (_): Remove useless defn, as system.h defines this.

10380 with latest obstack.h.
10381 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args

10384
10385 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
10386 so that this include file can stand alone.
10387 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
10388 does this now. Include subpipe.h first after config.h, to
10389 test whether it can stand alone.
10390
10391 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
10392 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
10393 unused declaration.
10394
10395 * tests/synclines.at (%union synch line): Put a dummy member in
10396 the union, because empty unions aren't allowed in C. Caught

10511 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
10512 There's no need to mention top_builddir since Automake does that
10513 for us.

10639 When reducing initial empty rules, Bison parser read an initial
10640 location that is not defined. This results in garbage, and that
10641 affects Bison's own parser. Therefore we need (i) to extend Bison

10643 this CVS Bison to fix CVS Bison's parser.

10927 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
10928 to g++, as GCC 3.3 complains if you do it.
10929 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
10930 everything that WARNING_CFLAGS has, except omit warnings
10931 not suitable for C++.
10932 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).

10936 Fix a GLR parser bug I reported in February; see
161a71f3 10937 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.

10938 The problem was that GLR parsers did not conform to the C standard,
10939 because actions like { $1 = $2 + $3; } expanded to expressions
10940 that invoked YYFILL in separate subexpressions, and YYFILL assigned
10941 to a local variable. The C standard says that expressions
10942 like (var = f ()) + (var = f ()) have undefined behavior.
10943 Another problem was that GCC sometimes issues warnings that
10944 yyfill and its parameters are unused.
10945
10946 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
10947 as possibly unused.
10948 (yyfill): New function.
10949 (YYFILL): Use it.
10950 (yyuserAction): Change type of yynormal to bool, so that it matches
10951 the new yyfill signature. Mark it as possibly unused.
10952
10953
10954 Follow up on a bug I reported in February, where a Bison-generated
10955 parser can loop. Provide a test case and a fix for yacc.c. I
10956 don't have a fix for lalr1.cc or for glr.c, unfortunately.
10957 The original bug report is in:

10959
10960 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
10961 macro's size was becoming unwieldy.
10962 (yyerrlab): Do not discard an empty lookahead symbol, as this
10963 might destroy garbage.
10964 (yyerrorlab): New label, with the old contents of YYERROR,
10965 plus the following change: pop the stack of rhs corresponding
10966 to the production that invoked YYERROR. That is how Yacc
10967 behaves, and POSIX requires this behavior.
10968 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
10969 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
10970 Define 'alarm' to do nothing if unistd.h is not available.
10971 Add a new rule "exp: '-' error;" to test the above change to
10972 data/yacc.c. Use 'alarm' to abort any test taking longer than
10973 10 seconds, as it's probably looping.
10974 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
10975 Also, the new yacc.c generates two fewer diagnostics for an
10976 existing test.

11604 we don't need to worry about yyerrlab1 being reported as an

11628 these elements have fake values.

11737 * doc/bison.texinfo (Understanding): Use Yacc style for
11738 conflict reports. Also, use new way of locating rules.
11739 * src/conflicts.c (conflict_report):
11740 Renamed from conflict_report_yacc, removing the old
11741 'conflict_report'. Translate the entire conflict report at once,
11742 so that we don't assume that "," has the same interpretation in
11743 all languages.
11744 (conflicts_output): Use Yacc-style conflict report for each state,
11745 instead of our more-complicated style.
11746 (conflicts_print): Use Yacc-style conflict report, except print
11747 the input file name when not emulating Yacc.
11748 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
11749 Conflicted Reduction, %expect not enough, %expect too much,

11761 Fix a bug where error locations were not being recorded correctly.
11762 This problem was originally reported by Paul Hilfinger in

11765 * data/yacc.c (yyparse): New local var yylerrsp, to record the
11766 top of the location stack's error locations.
11767 (yyerrlab): Set it. When discarding a token, push its location
11768 onto yylerrsp so that we don't lose track of the error's end.
11769 (yyerrlab1): Now is only the target of YYERROR, so that we can
11770 properly record the location of the action that failed. For GCC
11771 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
11772 GCC warning about yyerrlab1 being unused if YYERROR is unused.
11773 (yyerrlab2): New label, which yyerrlab now falls through to.
11774 Compute the error's location by applying YYLLOC_DEFAULT to
11775 the locations of all the symbols that went into the error.
11776 * doc/bison.texinfo (Location Default Action): Mention that
11777 YYLLOC_DEFAULT is also invoked for syntax errors.
11778 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
11779 Error locations include the locations of all the tokens that were
11780 discarded, not just the last token.

11837 If the user does not define YYSTYPE as a macro, Bison now declares it
11838 using typedef instead of defining it as a macro. POSIX requires this.
11839 For consistency, YYLTYPE is also declared instead of defined.
11840
11841 %union directives can now have a tag before the `{', e.g., the
11842 directive `%union foo {...}' now generates the C code
11843 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
11844 The default union tag is `YYSTYPE', for compatibility with Solaris 9
11845 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
11846 instead of `yyltype'.
11847
11848 `yystype' and `yyltype' are now obsolescent macros instead of being
11849 typedefs or tags; they are no longer documented and will be
11850 withdrawn in a future release.

11856 (YYLTYPE): Renamed from yyltype.
11857 (yyltype, yystype): New (and obsolescent) macros,
11858 for backward compatibility.
11859 * data/yacc.c: Likewise.
11860
11861 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
11862 does not specify a union tag. This is for compatibility with
11863 Solaris 9 yacc.
11864
11865 * src/parse-gram.y (add_param): 2nd arg is now char * not char

11882 has (or usually has) an immediately-following braced code.

11884 to return when scanning braced code.

12490 ((...));' if a single statement is desired (e.g. before `else').
12491 Work around GCC warnings by surrounding corresponding calls with

12843 Use new @ escapes consistently. Represent brackets with @{ and @}
12844 rather than @<:@ and @:>@, since this works a bit better with dumb
12845 editors like vi. Represent @ with @@, since @ is now consistently
12846 an escape. Use @oline@ and @ofile@ rather than __oline__ and
12847 __ofile__, to avoid unexpected expansions. Similarly, use @output
12848 rather than #output.
12849
12850 * data/c.m4 (b4_copyright): Omit file name from comment, since
12851 the file name could contain "*/".

12896
12897 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
12898 them with auto vars.
12899 Switch to new escape scheme, where @ is the escape character uniformly.
12900 Abort if a stray escape character is found. Avoid unbounded input
12901 buffer when parsing non-escaped text.

12913 (yygetLRActions, yyrecoverParseError): Use them.

12916 counted in the token inserted at end of file. Now takes
12917 location_t *, not location_t, so that the location can be
12918 adjusted. All uses changed.

13632 Let nondeterministic skeletons be usable with deterministic
13633 tables.
13634
13635 With the patch, GAWK compiled by GCC without -O2 passes its test
13636 suite using a GLR parser driven by LALR tables. It fails with -O2
13637 because `struct stat' gives two different answers on my machine:
13638 88 (definition of an auto var) and later 96 (memset on this var).
13639 Hence the stack is badly corrumpted. The headers inclusion is to
13640 blame: if I move the awk.h inclusion before GLR's system header
13641 inclusion, the two struct stat have the same size.

13695 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,

16162 of composing the error message from different bits.

16181 hard coded 2.
16182 (Even though this 2 is not the same as above: the number of the
16183 undeftoken remains being 2, it is its user token number which
16184 might not be 2).

16947 a conflict with the macro from lib/hash.h).

17086 problems: because Flex includes the headers *before* us,
17087 _GNU_SOURCE is not defined by config.h, and therefore strndup was
17088 not visible.

17106 Don't use %option yylineno: it seems that then Flex imagines
17107 REJECT has been used, and therefore it won't reallocate its

17109 in warnings for `unused: yy_flex_realloc'.

17415 these states are automatically computed from the initial state.
17416 (generate_states): Adjust.
17417 * src/print.c: When reporting a rule number to the user, substract
17418 1, so that the axiom rule is rule 0, and the first user rule is 1.
17419 * src/reduce.c: Likewise.

17424 0: `$axiom: START-SYMBOL $'.

17452 is the eoftoken.
17453 (packsymbols): No longer hack `tags' to insert `$' by hand.
17454 Be sure to preserve the value of the eoftoken.
17455 (reader): Make sure eoftoken is defined.
17456 Initialize nsyms to 0: now eoftoken is created just like the others.
17457 * src/print.c (print_grammar): Don't special case the eof token.
17458 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
17459 lie anyway, albeit pleasant.
17460 * tests/calc.at: Exercise error messages with eoftoken.
17461 Change the grammar so that empty input is invalid.

17554 Don't parse the user action that might follow the guard, let...
17555 (readgram): do it, i.e., now, there can be an action after a

17601 `lookaheadsp' member of the following state (since lookaheads of

17891 but that's to be addressed elsewhere.
17892 No longer output the rule numbers, but do output the state number.

18302 Because useless nonterminals are now kept alive (instead of being

18311 the number of occurrences of each symbol, and later reassigned to
18312 `shift_symbol', containing the symbol that can be shifted from a
18313 given state.
18314 Deobfuscate, i.e., allocate, use and free `symbol_count' here
18315 only, and...

18902 use abs. path to find config.h.

20698 The location tracking mechanism is precious for parse error

20734 Test also `--verbose', `--defines' and `--name-prefix'. Testing
20735 the latter demonstrates a flaw in the handling of non debugging
20736 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
20737 was used in order to simplify:
20738
20739 #if YYDEBUG
20740 if (yydebug)
20741 {
20742 ...

20748 if (yydebug)
20749 {
20750 ...
20751 }
20752

20755 foodebug'.

20805 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
20806 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
20807 difficult and introduced a lot of core dump. It turns out that
20808 Bison used an implementation of `xmalloc' based on `calloc', and
20809 at various places it does depend upon the initialization to 0. I
20810 have not tried to isolate the pertinent places, and all the former
20811 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,

21895 New function.
21896 (readgram): Use `#if 0' around code that accepted %command
21897 inside grammar rules: The documentation doesn't allow it,

21899 (parse_token_decl): Extended the %token
21900 declaration to allow a multi-character symbol as an alias.
21901 (parse_thong_decl): New function.
21902 (read_declarations): Added %thong declarations.

21912 Revised and use multiple warnxxx functions to avoid using VARARGS1.
21913 (read_declarations): Improve the error message for
21914 an invalid character. Do not abort.
21915 (read_declarations, copy_guard, copy_action): Use
21916 printable_version to avoid unprintable characters in printed output.
21917 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
21918 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):

21933
21934 * src/lex.h:
21935 Added THONG and NOOP for alias processing.

21939 Include getopt.h. Add some extern decls.
21940 (safegetc): New function to deal with EOF gracefully.
21941 (literalchar); new function to deal with reading \ escapes.
21942 (lex): Use literalchar.
21943 (lex): Implemented "..." tokens.
21944 (literalchar, lex, parse_percent_token): Made tokenbuffer
21945 always contain the token. This includes growing the token
21946 buffer while reading an integer.
21947 (parse_percent_token): Replaced if-else statement with percent_table.
21948 (parse_percent_token): Added % declarations as another
21949 way to specify the flags -n, -l, and -r. Also added hooks for
21950 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
21951 major changes to files.c.
21952 (lex) Retain in the incoming stream a character following
21953 an incorrect '/'.
21954 (skip_white_space, lex): Revised most error messages
21955 and changed fatal to warn to avoid aborting.
