13 Move sc_tight_scope into maint.mk.
14 It does not work, and I don't know how it was supposed to work: it seems
15 to be looking for sources in the build tree. I just moved it at a better
16 place, fixing it is still required.

30 * src/Makefile.am: Rename as...
31 * src/local.mk: this.
32 Prefix all the paths with src/.
33 (AUTOMAKE_OPTIONS): Build object files in the sub dirs.
34 (AM_CPPFLAGS): Find find in builddir/src.
35 (YACC): Move the flags into...
36 (AM_YFLAGS): here.
37 * maint.mk (sc_tight_scope): Disable.
38 It used to bounce to the version in src/Makefile.am which is now
39 part of this very Makefile.
40 * Makefile.am, configure.ac: Adjust.
41 * src/scan-code-c.c, src/scan-code.l: We can no longer rely on
42 include "..." to find files "here": we are no longer in src/, so
43 qualify the includes with src/.
44 * doc/Makefile.am (PREPATH): No longer include the top_builddir
45 prefix.
46 (.x.1): Adjust to be able to create src/foo from the top level
47 Makefile, instead of going bounce to src/Makefile the creation of
48 foo.

102
103 Instead of using make_symbol<TOK_FOO>, generate make_FOO for each token type.
104 Using template buys us nothing, and makes it uselessly complex to
105 construct a symbol. Besides, it could not be generalized to other
106 languages, while make_FOO would work in C/Java etc.

109 (b4_symbol): Use it.
110 (b4_symbol_constructor_declaration_)
111 (b4_symbol_constructor_definition_): Instead of generating
112 specializations of an overloaded template function, just generate
113 several functions whose names are forged from the token names
114 without the token.prefix.
115 (b4_symbol_constructor_declarations): Generate them for all the
116 symbols, not just by class of symbol type, now that instead of
117 specializing a function template by the token, we generate a
118 function named after the token.
119 (b4_symbol_constructor_specialization_)
120 (b4_symbol_constructor_specializations): Remove.

125 %define token.prefix.
126 Provide a means to add a prefix to the name of the tokens as output in the
127 generated files. Because of name clashes, it is good to have such a
128 prefix such as TOK_ that protects from names such as EOF, FILE etc.
129 But it clutters the grammar itself.

150 (yytoken_number_): Move into...
151 (symbol::token): here, since that's the only use.
152 The other one is YYPRINT which was not officially supported
153 by lalr1.cc, and anyway it did not work since YYPRINT uses this
154 array under a different name (yytoknum).

174 Define make_symbol in the header.
175 To reach good performances these functions should be inlined (yet this is
176 to measure precisely). To this end they must be available to the caller.

178 * data/lalr1.cc (b4_symbol_constructor_definition_): Qualify
179 location_type with the class name.
180 Since will now be output in the header, declare "inline".
181 No longer use b4_symbol_constructor_specializations, but
182 b4_symbol_constructor_definitions in the header.
183 Don't call it in the *.cc file.

194 Define the constructors of symbol_type in b4_symbol_constructor_definitions.
195 The constructors are called by the make_symbol functions, which a

197 together.

220 to refer to the class name to use a type defined by the class for
221 arguments of member functions.

224
225 Finer input type for yytranslate.
226 This patch is debatable: the tradition expects yylex to return an int
227 which happens to correspond to token_number (which is an enum). This
228 allows for instance to return characters (such as '*' etc.). But this
229 goes against the stronger typing I am trying to have with the new
230 lex interface which return a symbol_type. So in this case, feed
231 yytranslate_ with a token_type.
2df9ec37 232
4654b0c0

233 * data/lalr1.cc (yytranslate_): When in %define lex-symbol,

250 Use b4_type_names for the union type.
251 The union used to compute the size of the variant used to iterate over the
252 type of all the symbols, with a lot of redundancy. Now iterate over the
253 lists of symbols having the same type-name.

263 Define the "identifier" of a symbol.
264 Symbols may have several string representations, for instance if they
265 have an alias. What I call its "id" is a string that can be used as
266 an identifier. May not exist.
2df9ec37 267

268 Currently the symbols which have the "tag_is_id" flag set are those that

275 and "has_id".
276 Remove the definition of "tag_is_id".
277 * data/lalr1.cc: Use the "id" and "has_id" whereever "tag" and
278 "tag_is_id" were used to produce code.

408 Introduce make_symbol.
409 make_symbol provides a means to construct a full symbol (kind, value,
410 location) in a single shot. It is meant to be a Symbol constructor,
411 parameterized by the symbol kind so that overloading would prevent
412 incorrect kind/value pairs. Unfortunately parameterized constructors do
413 not work well in C++ (unless the parameter also appears as an argument,
414 which is not acceptable), hence the use of a function instead of a
415 constructor.

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

630 Change the handling of the symbols in the skeletons.
631 Before we were using tables which lines were the symbols and which
632 columns were things like number, tag, type-name etc. It is was
633 difficult to extend: each time a column was added, all the numbers had
634 to be updated (you asked for colon $2, not for "tag"). Also, it was
635 hard to filter these tables when only a subset of the symbols (say the
636 tokens, or the nterms, or the tokens that have and external number
637 *and* a type-name) was of interest.
de62edee 638
d69c9694
AD
639 Now instead of monolithic tables, we define one macro per cell. For
640 instance "b4_symbol(0, tag)" is a macro name which contents is
641 self-decriptive. The macro "b4_symbol" provides easier access to
642 these cells.

959 Add "%define assert" to variants.

961 ovewritten by a new one. This should not happen, as this will
962 probably leak.

964 Unfortunately this uncovered a bug in the C++ parser itself: the
965 lookahead value was not destroyed between two calls to yylex. For
966 instance if the previous lookahead was a std::string, and then an int,
967 then the value of the std::string was correctly taken (i.e., the
968 lookahead was now an empty string), but std::string structure itself
969 was not reclaimed.
de62edee 970
2d32fc9f
AD
971 This is now done in variant::build(other&) (which is used to take the
972 value of the lookahead): other is not only stolen from its value, it
973 is also destroyed. This incurs a new performance penalty of a few
974 percent, and union becomes faster again.

1255 Fuse the three stacks into a single one.
1256 In order to make it easy to perform benchmarks to ensure that there are no
1257 performance loss, lalr1.cc is forked into lalr1-fusion.cc. Eventually,
1258 lalr1-fusion.cc will replace lalr1.cc.
de62edee 1259
0e0ed236
AD
1260 Meanwhile, to make sure that lalr1-fusion.cc is correctly exercized by the
1261 test suite, the user must install a symbolic link from lalr1.cc to it.

1263 Instead of having three stacks (state, value, location), use a stack
1264 of triples. This considerably simplifies the code (and it will be
1265 easier not to require locations as currently does the C++ parser),
1266 and also gives a 10% speedup according to etc/bench (probably mainly since
1267 memory allocation is done once instead of three times).
de62edee 1268
0e0ed236

1269 Another motivation is to make it easier to destruct properly
1270 semantic values: now that they are bound to their state (hence
1271 symbol type) it will be easier to call the appropriate destructor.

1318 Use variants to support objects as semantic values.
1319 This patch was inspired by work by Michiel De Wilde. But he used Boost
1320 variants which (i) requires Boost on the user side, (ii) is slow, and
1321 (iii) has useless overhead (the parser knows the type of the semantic value
1322 there is no reason to duplicate this information as Boost.Variants do).

3023 * src/lalr.c (state_lookahead_tokens_count): For code readability,
3024 move the check for disabled transitions to an aver since conflict
3025 resolution hasn't happened yet.
3026
3027 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
3028 labels a state as inconsistent just because it has error transitions.
3029 The original form of this check appeared in revision 1.1 of lalr.c,
3030 which was committed on 1991-12-21. Now (at least), changing the
3031 consistency label on such a state appears to have no useful effect in
3032 any of the places it is examined, which I enumerate below. The key
3033 point to understanding each item in this enumeration is that a state
3034 with an error transition is labelled consistent in the first place only
3035 if it has no rules, so the check cannot matter for states that have
3036 rules. (1) Labelling a state as inconsistent will cause set_conflicts
3037 to try to identify its conflicts, and a state must have *rules* to have
3038 conflicts. (2) Labelling a state as inconsistent will affect how
3039 action_row sets the default *rule* for the state. (3) Labelling a
3040 state as inconsistent will cause build_relations to add lookback edges
3041 to *rules* in that state.
3042 * src/state.h (struct state): Word the comment for member consistent
3043 more carefully.

3681 Instead of having skeletons declare all valid %define variables and
3682 %code qualifiers, provide macros that retrieve the associated values
3683 and build these lists automatically. Thus Bison will now warn when a
3684 variable or qualifier is not used by the skeleton in the current
3685 invocation regardless of whether it might sometimes be used by that
3686 skeleton in other invocations. Also, move all %define value macros to
3687 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
3688 form, which is replaced by %code.
3689 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
3690 (b4_check_user_names): ... this, and change the series of valid name
3691 arguments to a single list argument for names used in the skeleton
3692 similar to the existing list argument for names used in the grammar.
3693 Warn instead of complaining.
3694 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
3695 values and %code code, to format %code code properly, and to build
3696 lists of all %define variables and %code qualifiers used in the
3697 skeleton: b4_skeleton_percent_define_variables and
3698 b4_skeleton_percent_code_qualifiers.
3699 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
3700 Remove, and...
3701 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
3702 the skeleton names lists can finish building first. In place of
3703 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
3704 expect the lists b4_user_percent_define_variables and
3705 b4_user_percent_code_qualifiers.
3706 * data/c++.m4: Where setting default values for b4_parser_class_name,
3707 b4_location_type, b4_filename_type, b4_namespace, and
3708 b4_define_location_comparison, update their names to the
3709 b4_percent_define_ namespace.
3710 * data/glr.c: Don't use b4_check_percent_define_variables and
3711 b4_check_percent_code_qualifiers. Use b4_get_percent_code.

3718 * data/yacc.c: Likewise, and don't call m4_exit in
3719 b4_use_push_for_pull_if or m4_wrap code will never execute.
3720 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
3721 Rename to...
3722 (muscle_grow_user_name_list): ... this for consistency with the
3723 terminology used in bison.m4.
3724 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
3725 %define variable names, and rename muscle used_percent_define_variables
3726 to user_percent_define_variables.
3727 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
3728 user_percent_code_qualifiers.

3825 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
3826 directives. Because these M4 macros might be called when the current
3827 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
3828 the previous removal of uses of m4_divert, which caused trouble.
3829 (b4_check_percent_code_qualifiers): Use b4_complain instead of

4051 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to

4150 Enable push parsers to operate in impure mode. Thus, %push-parser no
4151 longer implies %pure-parser. The point of this change is to move
4152 towards being able to test the push parser code by running the entire
4153 test suite as if %push-parser had been declared.
4154 * data/push.c (yypush_parse): For impure mode, remove the
4155 yypushed_char, yypushed_val, and yypushed_loc arguments.
4156 Instead, declare these as local variables initialized to the global
4157 yychar, yylval, and yylloc.
4158 For the first yypush_parse invocation only, restore the initial values
4159 of these global variables when it's time to read a token since they
4160 have been overwritten.
4161 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
4162 %push-parser.
4163 * tests/calc.at (Simple LALR(1) Calculator): Always declare

4208 initialized (with b4_location_initial_line and
4209 b4_location_initial_column) upon calling yypush_parse. However, that
4210 initialization now overwrites the first token's location;
4211 %initial-action assigning @$ already did the same thing, and both bugs

4426 @output_parser_name@ and @output_header_name@, which are now redundant.
4427 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
4428 b4_parser_file_name, b4_spec_defines_file, and the new
4429 @basename(FILENAME@) instead of @output_parser_name@ and
4430 @output_header_name@, which inappropriately escaped the file names as
4431 C string literals.

4436 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
4437 exactly what MUSCLE_INSERT_STRING used to do.

4439 characters are escaped properly.
4440 * src/output.c (prepare): Define muscle file_name_all_but_ext as
4441 all_but_ext.
4442 For pkgdatadir muscle, maintain previous functionality by using
4443 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
4444 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
4445 digraphs would never be expanded. Hopefully no one has M4-special
4446 characters in his Bison installation path.
4447 * src/scan-skel.l: Don't parse @output_header_name@ and

4798 Warn about unset midrule $$ if the corresponding $n is used.
4799 * src/reader.c (symbol_should_be_used): Check midrule parent rule for
4800 $n usage.
4801 (packgram): Before invoking grammar_rule_check on any rule, make sure
4802 all actions have already been scanned in order to set `used' flags.
4803 Otherwise, checking that a midrule's $$ is set will not always work
4804 properly because the midrule check must forward-reference the midrule's
4805 parent rule.
4806 * tests/input.at (AT_CHECK_UNUSED_VALUES): Extend to check the new
4807 warning.

5313 Whether the default %destructor/%printer applies to a particular symbol
5314 isn't a question of whether the user *declares* that symbol (in %token,
5315 for example). It's a question of whether the user by any means
5316 *defines* the symbol at all (by simply using a char token, for
5317 example). $end is defined by Bison whereas any other token with token
5318 number 0 is defined by the user. The error token is always defined by
5319 Bison regardless of whether the user declares it with %token, but we
5320 may one day let the user define error as a nonterminal instead.
5321 * NEWS (2.3+): Say "user-defined" instead of "user-declared".

5842 * src/scan-code.l (handle_action_dollar): Now that this is invoked
5843 after parsing the entire grammar file, the symbol list here in the case
5844 of a midrule is actually the midrule's empty RHS, so reference its
5845 parent rule's RHS where necessary.
5846 On the other hand, now that you can already know it's a midrule, you

5854 terminates a rule. symbol_list_print already does this correctly.
5855 * src/symlist.h (symbol_list.midrule_parent_rule,

6376 of that state is guaranteed to be resolved, and that's enough. This

6379 * tests/glr-regression.at (Uninitialized location when reporting

6381 Also, the embedded comments in this test case claim it checks the case
6382 of an empty RHS that has inherited the initial location. However, the
6383 corresponding LHS was already resolved, so yyresolveLocations didn't
6384 actually have reason to modify it. Fix this by forcing
6385 nondeterministic operation at the beginning of the parse.

6804 During deterministic GLR operation, user actions should be able to
6805 influence the parse by changing yychar. To make this easier to fix and

6834 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
6835 got from <http://bro-ids.org/download.html>. The bug is that
6836 when two actions appeared in succession, the second one was
6837 scanned before the first one was added to the grammar rule
6838 as a midrule action. Bison then output the incorrect warning
6839 "parse.y:905.17-906.36: warning: unused value: $3".

7125 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to
7126 use during nondeterministic operation to track which stacks have
7127 actually needed the current lookahead.

7129 Allocate, deallocate, resize, and otherwise shuffle space for
7130 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
7131 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
7132 appropriately during nondeterministic operation.
7133 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
7134 members to store the current lookahead to be used by the deferred
7135 user action.
7136 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
7137 from which the RHS is taken. Set the lookahead members of the new
7138 yySemanticOption according to the lookahead status for stack yyk.
7139 (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to
7140 yyaddDeferredAction.

7143 them back to their current values afterward.

7168 * data/glr.c (yyresolveValue): When merging semantic options, if at
7169 least one user action succeeds but a later one cuts the parse, then
7170 destroy the semantic value before returning rather than leaking it.
7171 (yyresolveStates): If a user action cuts the parse and thus
7172 yyresolveValue fails, ignore the (unset) semantic value rather than
7173 corrupting the yyGLRState, and empty the semantic options list since
7174 the user actions should have called all necessary destructors.
7175 Simplify code with YYCHK.

8293 New test, from Joel E. Denny in:

8306 * tests/regression.at (Token definitions): Don't rely on
8307 AT_PARSER_CHECK for data that contains backslashes. It currently
8308 uses 'echo', and 'echo' isn't portable if its argument contains
8309 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
8310 that the byte '\0xff' is not printable in the C locale; it is,
8311 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
8312 not printable, so use '\0x81' to test.

8327 Add __attribute__ ((__noreturn__)).

8330 "make maintainer-distcheck".
8331 * Makefile.maint: Merge from coreutils.
8332 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
8333 (syntax-check-rules): Change list of rules as described below.

8350 (signatures, %.asc): Remove.
8351 (rel-files, announcement): Remove signatures.
8352 Restore old updating code, even though we don't use it, so

8367 we comment out the Autoconf version number.
8368 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
8369 it's error-prone and "make maintainer-distcheck" rejects it.

8371 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.

8390 void, to avoid warning when NLS is disabled.
8391 * src/output.c: Include scan-skel.h.
8392 (scan_skel): Remove decl, since scan-skel.h does this.
8393 (output_skeleton):
8394 Indent calls to "error" to pacify "make maintainer-distcheck".
8395 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.

8397 "make maintainer-distcheck".
8398 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):

8407 not @VAR@.

8410 "make maintainer-distcheck" complained about.

8412 * examples/extexi (message): Don't print a message more than once,
8413 and omit line-number decoration that makes Emacs compile think
8414 that informative messages are worth worrying about.

8421 accidentally.
8422 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
8423 autogenerated by the maintainer.
8424 * examples/calc++/.cvsignore: Add *.yy.
8425
8426 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
8427 * lib/bitset_stats.c (bitset_stats_init): Likewise.
8428 * lib/bitsetv.c (bitsetv_alloc): Likewise.
8429
8430 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.

8433 from maintainer-distcheck about casting the argument of 'free'.
8434
8435 * NEWS: Mention recent yytname changes.
8436 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
8437
8438 * bootstrap: For translations that have not yet been upgraded to
8439 the new runtime-po domain, prime the pump by extracting the
8440 relevant strings from the obsolete translations. This code can be
8441 removed once the bison-runtime domain has been translated by each
8442 team.
8443
8444 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
8445 now that token names are already quoted.
8446
8447 Fix problem reported by Anthony Heading.
8448 * data/glr.c (YYTOKEN_TABLE): New macro.

8461 (yyreportSyntaxError): Use it to dequote most string literals.
8462 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
8463 with other skeletons. All uses changed.

8468 * doc/bison.texinfo (Decl Summary, Calling Convention):
8469 Clarify quoting convention of yytname.
8470 * src/output.c (prepare_symbols): Quote all names. This undoes
8471 the 2005-04-17 change, which is now accomplished (mostly) via
8472 changes in the parsers as described above.
8473 * tests/regression.at (Token definitions, Web2c Actions):
8474 Undo most 2005-04-17 change here, too.
8475
84762005-07-20 Paul Eggert <eggert@cs.ucla.edu>
8477
8478 Fix more problems reported by twlevo@xs4all.nl.
8479 * tests/cxx-type.at: Don't pipe output of ./types through sed to
8480 remove trailing spaces. This loses the exit status of ./types,
8481 and isn't needed since ./types shouldn't be emitting trailing
8482 spaces.
8483 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
8484 as the stack isn't valid in that case.
8485
8486 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
8487 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
8488 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
8489 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
8490 is used.
8491 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
8492 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):

8496 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
8497 overly-picky compilers that reject 'char *foo = "bar";'.
8498
8499 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
8500 to FILE * parameter, not to stderr. This fixes a typo introduced
8501 in the 2005-07-12 change.
8502
8503 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
8504 warnings from GCC 4.
8505

8509 (yyglrShift): Remove unused parameters b4_user_formals.

8515 Destructor cleanups and regularization among the three skeletons.
8516 * NEWS: Document the behavior changes.
8517 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
8518 stack before failing, as the cleanup code will do it for us now.
8519 * data/lalr1.cc (yyerrlab): Likewise.
8520 * data/glr.c (yyparse): Pop everything off the stack before
8521 freeing it, so that destructors get called properly.
8522 * data/lalr1.cc (yyreturn): Likewise.
8523 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
8524 This is more consistent.

8528 Some English-language cleanups for %destructor.
8529 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

8538 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
8539 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
8540 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
8541 Rename yyoverflowab to yyexhaustedlab.
8542 When memory exhaustion occurs during syntax-error reporting,
8543 report it separately rather than in a single diagnostic; this
8544 eases translation.
8545 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
8546 (Memory Exhausted): Renamed from Parser Stack Overflow.

8553 skeleton; a C++ expert needs to finish this. Remove debugging
8554 msgids; there's little point to having them translated, since they
8555 can be understood only by someone who can read the
8556 (English-language) source code.
8557
8558 Generate runtime-po/bison-runtime.pot automatically, so that we
8559 don't have to worry about garbage getting in that file. We'll
8560 make sure after the next official release that old msgids don't
8561 get lost. See

8563
8564 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
8565 Now auto-generated.
8566 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
8567 Fix typos in explanations of the runtime file.
8568 * bootstrap: Change gettext keyword from YYI18N to YY_.
8569 Use standard Makefile.in.in in runtime-po, since we'll arrange
8570 for backward-compatible bison-runtime.po files in a different way.
8571 * data/glr.c (YY_): New macro, from yacc.c.
8572 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
8573 Translate messages intended for users.
8574 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
8575 the wording in the other skeletons. We don't know that the memory
8576 is virtual.
8577 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
8578 Use same method that yacc.c uses.
8579 Don't translate debugging messages.
8580 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
8581 it doesn't work (yet), and requires C++ expertise to fix.
8582 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
8583 Move defn to a more logical place, to be consistent with other
8584 skeletons.
8585 Don't translate debugging messages.
8586 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
8587 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
8588 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
8589 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.

8604 can handle the problem.
8605 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
8606 (yyparse): New local variable yyresult to record the result.

8612 if YYABORT is used).

9793 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
9794 whether the reducion was empty or not. This leaves room to
9795 improve the use of YYLLOC_DEFAULT in such a case.
9796 lalr1.cc is still experimental, so changing this is acceptable.

9933 * data/lalr1.cc (symprint_): Output the location.

9935 output the location within the %printer.
9936 Activate GLR tests, at least to make sure they compile properly.
9937 They still don't pass though.

9942
9943 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
9944 Bison directive from the Bison file to the invocation of this
9945 macro, so that these directives are passed to
9946 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
9947 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
9948 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
9949 the extra Bison directives instead of the whole series.
9950 Change the grammar so that there are recoverable errors, and
9951 unrecoverable errors. Now we can have the parser give up before
9952 consuming the whole input. As a result we now can observe that
9953 the lookahead is freed when needed.
9954 Change the parser source to parse argv[1] instead of a hard coded
9955 string.
9956 Simplify yylex, and give a value and location to EOF.
9957 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
9958 passed directives already coded in the file.
9959 Add some tests to check the location of "error".
9960 For some tests, the C++ parser is correct, and not yacc.c.
9961 For other tests, they provide different, but unsatisfying, values,
9962 so keep the C++ value so that at least one parser is "correct"
9963 according to the test suite.
9964 (Actions after errors): Remove, this is subsumed by the
9965 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

10146 a seemingly endless set of combinations of versions more recent
10147 than that. The bottom line is that the current sources require
10148 fairly recent versions of the build tools, and it'll be some work

10665 When reducing initial empty rules, Bison parser read an initial
10666 location that is not defined. This results in garbage, and that
10667 affects Bison's own parser. Therefore we need (i) to extend Bison

10962 Fix a GLR parser bug I reported in February; see

10964 The problem was that GLR parsers did not conform to the C standard,
10965 because actions like { $1 = $2 + $3; } expanded to expressions
10966 that invoked YYFILL in separate subexpressions, and YYFILL assigned
10967 to a local variable. The C standard says that expressions
10968 like (var = f ()) + (var = f ()) have undefined behavior.
10969 Another problem was that GCC sometimes issues warnings that
10970 yyfill and its parameters are unused.
10971
10972 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
10973 as possibly unused.
10974 (yyfill): New function.
10975 (YYFILL): Use it.
10976 (yyuserAction): Change type of yynormal to bool, so that it matches
10977 the new yyfill signature. Mark it as possibly unused.

10980 Follow up on a bug I reported in February, where a Bison-generated
10981 parser can loop. Provide a test case and a fix for yacc.c. I
10982 don't have a fix for lalr1.cc or for glr.c, unfortunately.
10983 The original bug report is in:

10986 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
10987 macro's size was becoming unwieldy.
10988 (yyerrlab): Do not discard an empty lookahead symbol, as this
10989 might destroy garbage.
10990 (yyerrorlab): New label, with the old contents of YYERROR,
10991 plus the following change: pop the stack of rhs corresponding
10992 to the production that invoked YYERROR. That is how Yacc
10993 behaves, and POSIX requires this behavior.
10994 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
10995 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
10996 Define 'alarm' to do nothing if unistd.h is not available.
10997 Add a new rule "exp: '-' error;" to test the above change to
10998 data/yacc.c. Use 'alarm' to abort any test taking longer than
10999 10 seconds, as it's probably looping.
11000 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
11001 Also, the new yacc.c generates two fewer diagnostics for an
11002 existing test.

11628
11629 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
11630 we don't need to worry about yyerrlab1 being reported as an
11631 "unused label" by non-GCC C compilers. The downside is that if
11632 locations are used then a couple of statements are duplicated each
11633 time YYERROR is invoked, but the upside is that the warnings
11634 should vanish.
11635 (yyerrlab1): Move code to YERROR.
11636 (yyerrlab2): Remove. Change uses back to yyerrlab1.
11637 This reverts some of the 2002-12-27 change.

11649 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
11650 when the stacks contain one element, as the loop would otherwise
11651 free the last state, and then use the top state (the one we just
11652 popped). This means that the initial elements will not be freed
11653 explicitly, as is the case in yacc.c; it is not a problem, as
11654 these elements have fake values.

11760
11761 Switch back to the Yacc style of conflict reports, undoing some
11762 of the 2002-07-30 change.
11763 * doc/bison.texinfo (Understanding): Use Yacc style for
11764 conflict reports. Also, use new way of locating rules.
11765 * src/conflicts.c (conflict_report):
11766 Renamed from conflict_report_yacc, removing the old
11767 'conflict_report'. Translate the entire conflict report at once,
11768 so that we don't assume that "," has the same interpretation in
11769 all languages.
11770 (conflicts_output): Use Yacc-style conflict report for each state,
11771 instead of our more-complicated style.
11772 (conflicts_print): Use Yacc-style conflict report, except print
11773 the input file name when not emulating Yacc.
11774 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
11775 Conflicted Reduction, %expect not enough, %expect too much,
11776 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
11777 * tests/existing.at (GNU Cim Grammar): Likewise.

11779

11787 Fix a bug where error locations were not being recorded correctly.
11788 This problem was originally reported by Paul Hilfinger in

11790
11791 * data/yacc.c (yyparse): New local var yylerrsp, to record the
11792 top of the location stack's error locations.
11793 (yyerrlab): Set it. When discarding a token, push its location
11794 onto yylerrsp so that we don't lose track of the error's end.
11795 (yyerrlab1): Now is only the target of YYERROR, so that we can
11796 properly record the location of the action that failed. For GCC
11797 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
11798 GCC warning about yyerrlab1 being unused if YYERROR is unused.
11799 (yyerrlab2): New label, which yyerrlab now falls through to.
11800 Compute the error's location by applying YYLLOC_DEFAULT to
11801 the locations of all the symbols that went into the error.
11802 * doc/bison.texinfo (Location Default Action): Mention that
11803 YYLLOC_DEFAULT is also invoked for syntax errors.
11804 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
11805 Error locations include the locations of all the tokens that were
11806 discarded, not just the last token.

11863 If the user does not define YYSTYPE as a macro, Bison now declares it
11864 using typedef instead of defining it as a macro. POSIX requires this.
11865 For consistency, YYLTYPE is also declared instead of defined.
11866
11867 %union directives can now have a tag before the `{', e.g., the
11868 directive `%union foo {...}' now generates the C code
11869 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
11870 The default union tag is `YYSTYPE', for compatibility with Solaris 9
11871 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
11872 instead of `yyltype'.
11873
11874 `yystype' and `yyltype' are now obsolescent macros instead of being
11875 typedefs or tags; they are no longer documented and will be
11876 withdrawn in a future release.
11877
11878 * data/glr.c (b4_location_type): Remove.

11881 (struct YYLTYPE): Renamed from struct yyltype.
11882 (YYLTYPE): Renamed from yyltype.
11883 (yyltype, yystype): New (and obsolescent) macros,
11884 for backward compatibility.
11885 * data/yacc.c: Likewise.
11886
11887 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
11888 does not specify a union tag. This is for compatibility with
11889 Solaris 9 yacc.
11890
11891 * src/parse-gram.y (add_param): 2nd arg is now char * not char

11894 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,

11908 has (or usually has) an immediately-following braced code.

11910 to return when scanning braced code.

12311 instead of returning ID immediately, since we need to search for
12312 a subsequent colon.
12313 (<INITIAL>"'", "\""): Save token_start.

12869 Use new @ escapes consistently. Represent brackets with @{ and @}
12870 rather than @<:@ and @:>@, since this works a bit better with dumb
12871 editors like vi. Represent @ with @@, since @ is now consistently
12872 an escape. Use @oline@ and @ofile@ rather than __oline__ and
12873 __ofile__, to avoid unexpected expansions. Similarly, use @output
12874 rather than #output.
12875
12876 * data/c.m4 (b4_copyright): Omit file name from comment, since
12877 the file name could contain "*/".

12920 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
12921 Use new escapes @{ and @} for [ and ].
12922
12923 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
12924 them with auto vars.
12925 Switch to new escape scheme, where @ is the escape character uniformly.
12926 Abort if a stray escape character is found. Avoid unbounded input
12927 buffer when parsing non-escaped text.

12939 (yygetLRActions, yyrecoverParseError): Use them.

12941 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
12942 counted in the token inserted at end of file. Now takes
12943 location_t *, not location_t, so that the location can be
12944 adjusted. All uses changed.

13166 as well as \000. Check for UCHAR_MAX, not 255.

13213 indicates one.
13214 * src/output.c (output_skeleton): Use xfclose rather than fclose

13281 The last OS that we could find where this wouldn't work is
13282 SunOS 3.5, and that's too old to worry about now.
13283
13284 * data/glr.c (struct yyltype): Define members even when not

13303 * configure.ac (AC_HEADER_STDBOOL): Add.

13523 Stop using the "enum_" trick for K&R-style function definitions;

13658 Let nondeterministic skeletons be usable with deterministic
13659 tables.
13660
13661 With the patch, GAWK compiled by GCC without -O2 passes its test
13662 suite using a GLR parser driven by LALR tables. It fails with -O2
13663 because `struct stat' gives two different answers on my machine:
13664 88 (definition of an auto var) and later 96 (memset on this var).
13665 Hence the stack is badly corrumpted. The headers inclusion is to
13666 blame: if I move the awk.h inclusion before GLR's system header
13667 inclusion, the two struct stat have the same size.

13721 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,

13832 the C Standard, which requires that structure types in different
13833 modules must be compatible if one is to be passed to the other.
13834 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
13835 All instances of "struct bitset_struct *" replaced with "bitset".

13851 function is of a different type U. Standard C requires that a

17331 the other tests pass correctly, the table look OK, even though the

17441 these states are automatically computed from the initial state.
17442 (generate_states): Adjust.
17443 * src/print.c: When reporting a rule number to the user, substract
17444 1, so that the axiom rule is rule 0, and the first user rule is 1.
17445 * src/reduce.c: Likewise.

17450 0: `$axiom: START-SYMBOL $'.

17452 number of the states has changed (the final state is no longer
17453 necessarily the last), catch up.

17477 (parse_token_decl): If the token being defined has value `0', it
17478 is the eoftoken.
17479 (packsymbols): No longer hack `tags' to insert `$' by hand.
17480 Be sure to preserve the value of the eoftoken.
17481 (reader): Make sure eoftoken is defined.
17482 Initialize nsyms to 0: now eoftoken is created just like the others.
17483 * src/print.c (print_grammar): Don't special case the eof token.
17484 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
17485 lie anyway, albeit pleasant.
17486 * tests/calc.at: Exercise error messages with eoftoken.
17487 Change the grammar so that empty input is invalid.

18328 Because useless nonterminals are now kept alive (instead of being

18338 `shift_symbol', containing the symbol that can be shifted from a
18339 given state.
18340 Deobfuscate, i.e., allocate, use and free `symbol_count' here
18341 only, and...

20724 The location tracking mechanism is precious for parse error
20725 messages. Nevertheless, it is enabled only when `@n' is used in
20726 the grammar, which is a different issue (you can use it in error

20760 Test also `--verbose', `--defines' and `--name-prefix'. Testing
20761 the latter demonstrates a flaw in the handling of non debugging
20762 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
20763 was used in order to simplify:
20764
20765 #if YYDEBUG

20774 if (yydebug)
20775 {
20776 ...

20831 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
20832 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
20833 difficult and introduced a lot of core dump. It turns out that
20834 Bison used an implementation of `xmalloc' based on `calloc', and
20835 at various places it does depend upon the initialization to 0. I
20836 have not tried to isolate the pertinent places, and all the former
20837 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,

21926 declaration to allow a multi-character symbol as an alias.
21927 (parse_thong_decl): New function.

21938 Revised and use multiple warnxxx functions to avoid using VARARGS1.
21939 (read_declarations): Improve the error message for
21940 an invalid character. Do not abort.
21941 (read_declarations, copy_guard, copy_action): Use
21942 printable_version to avoid unprintable characters in printed output.

21968 (lex): Use literalchar.
21969 (lex): Implemented "..." tokens.
21970 (literalchar, lex, parse_percent_token): Made tokenbuffer
21971 always contain the token. This includes growing the token
21972 buffer while reading an integer.
21973 (parse_percent_token): Replaced if-else statement with percent_table.
21974 (parse_percent_token): Added % declarations as another
21975 way to specify the flags -n, -l, and -r. Also added hooks for
21976 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
21977 major changes to files.c.
21978 (lex) Retain in the incoming stream a character following
21979 an incorrect '/'.
21980 (skip_white_space, lex): Revised most error messages
