44 Make yyparser::error public.
45 * data/lalr1.cc: here.
46 There is no good reason to keep it private (and it is convenient
47 to use it from the scanner for instance). It is already public in
48 glr.cc.

30c10faf
AD
270 Instead of defining complex list of tuples to define various
271 properties of the symbols, we now prefer to define symbols as
272 "structs" in m4: using the symbol key (its number), and the
273 property name, b4_symbol gives it value. Use this to handle
274 destructors and printers.

299 Convert lib/Makefile.am into lib/local.mk.
300 The real problem is rather gnulib.mk, which itself is extracted
301 from a Makefile.am that gnulib expects to the "recursive". The
302 tool prefix-gnulib-mk converts such a gnulib.mk to be
303 non-recursive. Also, some AC_SUBST variables need to be adjusted.
304
305 * etc/prefix-gnulib-mk: New.
306 * bootstrap (slurp): Use it to convert further gnulib.mk.
307 No longer try to avoid re-creation of lib/gnulib.mk as the changes
308 are deeper.
309 * lib/Makefile.am: Rename as...
310 * lib/local.mk: this.
311 Adjust to be prefixed.

441 displaying the top of the stack before a reduction. But the
442 symbol type is available from the state stack. This has two be
443 benefits: two tables less in the parser (making it smaller), and a
444 more consistent use of the three stacks which will help to fuse
445 them.

961 Finer input type for yytranslate.
962 This patch is debatable: the tradition expects yylex to return an int
963 which happens to correspond to token_number (which is an enum). This
964 allows for instance to return characters (such as '*' etc.). But this
965 goes against the stronger typing I am trying to have with the new
966 lex interface which return a symbol_type. So in this case, feed
967 yytranslate_ with a token_type.

b06df3c2
AD
1145 make_symbol provides a means to construct a full symbol (kind,
1146 value, location) in a single shot. It is meant to be a Symbol
1147 constructor, parameterized by the symbol kind so that overloading
1148 would prevent incorrect kind/value pairs. Unfortunately
1149 parameterized constructors do not work well in C++ (unless the
1150 parameter also appears as an argument, which is not acceptable),
1151 hence the use of a function instead of a constructor.

1366 Change the handling of the symbols in the skeletons.
1367 Before we were using tables which lines were the symbols and which
1368 columns were things like number, tag, type-name etc. It is was
1369 difficult to extend: each time a column was added, all the numbers had
1370 to be updated (you asked for colon $2, not for "tag"). Also, it was
1371 hard to filter these tables when only a subset of the symbols (say the
1372 tokens, or the nterms, or the tokens that have and external number
1373 *and* a type-name) was of interest.
de62edee 1374
d69c9694
AD
1375 Now instead of monolithic tables, we define one macro per cell. For
1376 instance "b4_symbol(0, tag)" is a macro name which contents is
1377 self-decriptive. The macro "b4_symbol" provides easier access to
1378 these cells.

1701 Unfortunately this uncovered a bug in the C++ parser itself: the
1702 lookahead value was not destroyed between two calls to yylex. For
1703 instance if the previous lookahead was a std::string, and then an int,
1704 then the value of the std::string was correctly taken (i.e., the
1705 lookahead was now an empty string), but std::string structure itself
1706 was not reclaimed.
de62edee 1707

1708 This is now done in variant::build(other&) (which is used to take the
1709 value of the lookahead): other is not only stolen from its value, it
1710 is also destroyed. This incurs a new performance penalty of a few
1711 percent, and union becomes faster again.

1992 Fuse the three stacks into a single one.

b06df3c2
AD
1994 In order to make it easy to perform benchmarks to ensure that
1995 there are no performance loss, lalr1.cc is forked into
1996 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
1997 lalr1.cc.
1998
1999 Meanwhile, to make sure that lalr1-fusion.cc is correctly
2000 exercized by the test suite, the user must install a symbolic link
2001 from lalr1.cc to it.

2003 Instead of having three stacks (state, value, location), use a
2004 stack of triples. This considerably simplifies the code (and it
2005 will be easier not to require locations as currently does the C++
2006 parser), and also gives a 10% speedup according to
2007 etc/bench (probably mainly since memory allocation is done once
2008 instead of three times).
de62edee 2009

2010 Another motivation is to make it easier to destruct properly
2011 semantic values: now that they are bound to their state (hence
2012 symbol type) it will be easier to call the appropriate destructor.

2059 Use variants to support objects as semantic values.
b06df3c2
AD
2060 This patch was inspired by work by Michiel De Wilde. But he used
2061 Boost variants which (i) requires Boost on the user side, (ii) is
2062 slow, and (iii) has useless overhead (the parser knows the type of
2063 the semantic value there is no reason to duplicate this
2064 information as Boost.Variants do).
2065
2066 This implementation reserves a buffer large enough to store the
2067 largest objects. yy::variant implements this buffer. It was
2068 implemented with Quentin Hocquet.

2634 * tests/regression.at (Token definitions): Because of the change in
2635 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
2636 escapes trigraphs in symbol names. Thus, yytname no longer has
2637 trigraphs unnecessarily doubly escaped. Update test case output.

2639 have trigraphs in symbol names unnecessarily escaped once.

3765 * src/lalr.c (state_lookahead_tokens_count): For code readability,
3766 move the check for disabled transitions to an aver since conflict
3767 resolution hasn't happened yet.
3768
3769 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
3770 labels a state as inconsistent just because it has error transitions.
3771 The original form of this check appeared in revision 1.1 of lalr.c,
3772 which was committed on 1991-12-21. Now (at least), changing the
3773 consistency label on such a state appears to have no useful effect in
3774 any of the places it is examined, which I enumerate below. The key
3775 point to understanding each item in this enumeration is that a state
3776 with an error transition is labelled consistent in the first place only
3777 if it has no rules, so the check cannot matter for states that have
3778 rules. (1) Labelling a state as inconsistent will cause set_conflicts
3779 to try to identify its conflicts, and a state must have *rules* to have
3780 conflicts. (2) Labelling a state as inconsistent will affect how
3781 action_row sets the default *rule* for the state. (3) Labelling a
3782 state as inconsistent will cause build_relations to add lookback edges
3783 to *rules* in that state.
3784 * src/state.h (struct state): Word the comment for member consistent
3785 more carefully.

4294 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use

4423 Instead of having skeletons declare all valid %define variables and

4426 variable or qualifier is not used by the skeleton in the current
4427 invocation regardless of whether it might sometimes be used by that
4428 skeleton in other invocations. Also, move all %define value macros to
4429 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
4430 form, which is replaced by %code.
4431 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...

4856 * Makefile.am (SUBDIRS): Add etc subdirectory.
4857 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
4858 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
4859 yytoken, yyval, and yyloc declarations to...
4860 (yyparse or yypush_parse): ... here to improve performance. For
4861 yypush_parse invocations after the first, be sure to assign yyn its old
4862 value again.
4863 (yypstate_new): Don't bother initializing the yyresult field since the
4864 initial value isn't used.
4865 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
4866 remove the #define that, in push mode, set it to yyps->NAME.
4867 * etc/Makefile.am: New.
4868 * etc/bench.pl: Remove and build it instead from...

4871 invoking "bison" from $PATH.

4875 push.c, impure, pure, pull, and push.

4892 Enable push parsers to operate in impure mode. Thus, %push-parser no
4893 longer implies %pure-parser. The point of this change is to move
4894 towards being able to test the push parser code by running the entire
4895 test suite as if %push-parser had been declared.
4896 * data/push.c (yypush_parse): For impure mode, remove the
4897 yypushed_char, yypushed_val, and yypushed_loc arguments.
4898 Instead, declare these as local variables initialized to the global
4899 yychar, yylval, and yylloc.
4900 For the first yypush_parse invocation only, restore the initial values
4901 of these global variables when it's time to read a token since they
4902 have been overwritten.

4947 Rearrange initialization of the parser state variables so that the

4949 mode. This patch also fixes at least a bug such that yylloc was not
4950 initialized (with b4_location_initial_line and
4951 b4_location_initial_column) upon calling yypush_parse. However, that
4952 initialization now overwrites the first token's location;
4953 %initial-action assigning @$ already did the same thing, and both bugs
4954 will be fixed in a later patch.

6055 Whether the default %destructor/%printer applies to a particular symbol
6056 isn't a question of whether the user *declares* that symbol (in %token,
6057 for example). It's a question of whether the user by any means
6058 *defines* the symbol at all (by simply using a char token, for
6059 example). $end is defined by Bison whereas any other token with token
6060 number 0 is defined by the user. The error token is always defined by
6061 Bison regardless of whether the user declares it with %token, but we
6062 may one day let the user define error as a nonterminal instead.
6063 * NEWS (2.3+): Say "user-defined" instead of "user-declared".

6074 of '$', which a user symbol cannot have, and check for the error token.

6111 (symbols_pack): Since symbol_make_alias still does not decrement symbol

6132 (symbol_make_alias): It's not necessary to decrement the symbol and
6133 token counts anymore. Don't assume that an alias declaration occurs
6134 before any uses of the identifier or string, and thus don't assert that

6578 rule.

6580 since not all symbol declarations may have been parsed yet and, thus,
6581 warnings about types for $$, $n, @$, and @n can't be reported yet.
6582 (packgram): Translate the action and invoke grammar_rule_check now that
6583 all symbol declarations have been parsed.
6584 * src/scan-code.l (handle_action_dollar): Now that this is invoked
6585 after parsing the entire grammar file, the symbol list here in the case
6586 of a midrule is actually the midrule's empty RHS, so reference its
6587 parent rule's RHS where necessary.
6588 On the other hand, now that you can already know it's a midrule, you

6596 terminates a rule. symbol_list_print already does this correctly.
6597 * src/symlist.h (symbol_list.midrule_parent_rule,

6796 The Translation Project changed its way of publishing translations
6797 to maintainers. I haven't received any responses to my request
6798 for supporting the old way, or for documenting the new way. I
6799 have modified 'bootstrap' to use screen scraping
6800 (in this case, HTML scraping). This is unreliable and inelegant,

7576 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
7577 got from <http://bro-ids.org/download.html>. The bug is that
7578 when two actions appeared in succession, the second one was
7579 scanned before the first one was added to the grammar rule
7580 as a midrule action. Bison then output the incorrect warning
7581 "parse.y:905.17-906.36: warning: unused value: $3".

9181 the new runtime-po domain, prime the pump by extracting the
9182 relevant strings from the obsolete translations. This code can be
9183 removed once the bison-runtime domain has been translated by each

9213 the 2005-04-17 change, which is now accomplished (mostly) via
9214 changes in the parsers as described above.

9220 Fix more problems reported by twlevo@xs4all.nl.
9221 * tests/cxx-type.at: Don't pipe output of ./types through sed to
9222 remove trailing spaces. This loses the exit status of ./types,
9223 and isn't needed since ./types shouldn't be emitting trailing
9224 spaces.
9225 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
9226 as the stack isn't valid in that case.

9239 overly-picky compilers that reject 'char *foo = "bar";'.
9240
9241 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
9242 to FILE * parameter, not to stderr. This fixes a typo introduced
9243 in the 2005-07-12 change.
9244
9245 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid

9259 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
9260 stack before failing, as the cleanup code will do it for us now.
9261 * data/lalr1.cc (yyerrlab): Likewise.
9262 * data/glr.c (yyparse): Pop everything off the stack before
9263 freeing it, so that destructors get called properly.

9283 Rename yyoverflowab to yyexhaustedlab.
9284 When memory exhaustion occurs during syntax-error reporting,
9285 report it separately rather than in a single diagnostic; this
9286 eases translation.

9297 can be understood only by someone who can read the
9298 (English-language) source code.
9299
9300 Generate runtime-po/bison-runtime.pot automatically, so that we
9301 don't have to worry about garbage getting in that file. We'll
9302 make sure after the next official release that old msgids don't
9303 get lost. See

9308 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
9309 Fix typos in explanations of the runtime file.
9310 * bootstrap: Change gettext keyword from YYI18N to YY_.
9311 Use standard Makefile.in.in in runtime-po, since we'll arrange
9312 for backward-compatible bison-runtime.po files in a different way.
9313 * data/glr.c (YY_): New macro, from yacc.c.
9314 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
9315 Translate messages intended for users.
9316 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
9317 the wording in the other skeletons. We don't know that the memory
9318 is virtual.
9319 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
9320 Use same method that yacc.c uses.
9321 Don't translate debugging messages.
9322 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
9323 it doesn't work (yet), and requires C++ expertise to fix.
9324 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
9325 Move defn to a more logical place, to be consistent with other
9326 skeletons.
9327 Don't translate debugging messages.
9328 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
9329 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
9330 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
9331 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.

9354 if YYABORT is used).

9506 * data/yacc.c (yyparse): In the initial action, set
9507 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
9508 This avoids the use of undefined variables if the initial
9509 action does not set yylloc and/or yylval.

9517 not GNU M4, and that it works with any POSIX-compatible Awk.
9518 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
9519 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
9520 so that we also get calc++-parser.yy. Geneate it.
9521 Use $(AWK), not gawk, since any conforming Awk will do.
9522 Put comment before action, since older 'make' can't handle comment
9523 in action.

9550 never had any % directives, we can simply pass it to yyerror.

9561 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
9562 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
9563 so that we don't have to maintain their signatures.
9564 (yyFail): Check for buffer overflow, by using vsnprintf rather
9565 than vsprintf. Allocate a bigger buffer if possible.
9566 Report an error if buffer allocation fails.
9567 (yyStackOverflow): New function.
9568 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
9569 the initialization was successful. It might fail if storage was
9570 exhausted.
9571 (yyexpandGLRStack): Add more checks for storage allocation failure.
9572 Use yyStackOverflow to report failures.

9579 changed.
9580 (yyresolveValue): Use yybool for boolean.
9581 (yyreportSyntaxError): Check for size-calculation overflow.

10297 use exactly the same macro in both places.

10370 for initial core. Just have a separate core, so we needn't worry
10371 about whether kernel_size and kernel_base are initialized.
10372

10382
10383 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
10384 This is because all callers pass unsigned int.

10386
10387 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
10388 (build_relations): Initialize includes[i] in all cases.

10396 conflict_list[0] was always 0, but now it isn't initialized.

10535 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
10536 whether the reducion was empty or not. This leaves room to
10537 improve the use of YYLLOC_DEFAULT in such a case.
10538 lalr1.cc is still experimental, so changing this is acceptable.
10539 And finally, there are probably not many users who changed the
10540 handling of locations in GLR, so changing is admissible too.

10685 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
10686 Bison directive from the Bison file to the invocation of this
10687 macro, so that these directives are passed to
10688 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
10689 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
10690 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
10691 the extra Bison directives instead of the whole series.
10692 Change the grammar so that there are recoverable errors, and
10693 unrecoverable errors. Now we can have the parser give up before
10694 consuming the whole input. As a result we now can observe that
10695 the lookahead is freed when needed.
10696 Change the parser source to parse argv[1] instead of a hard coded
10697 string.
10698 Simplify yylex, and give a value and location to EOF.
10699 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
10700 passed directives already coded in the file.
10701 Add some tests to check the location of "error".
10702 For some tests, the C++ parser is correct, and not yacc.c.
10703 For other tests, they provide different, but unsatisfying, values,
10704 so keep the C++ value so that at least one parser is "correct"
10705 according to the test suite.
10706 (Actions after errors): Remove, this is subsumed by the
10707 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

10888 a seemingly endless set of combinations of versions more recent

10890 fairly recent versions of the build tools, and it'll be some work

11024 on them being in our CVS. Upgrade to latest versions of gnulib
11025 and Automake.

11028 * bootstrap: Bootstrap from gnulib and po repositories.
11029 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
11030 * README-cvs: Document these changes. Remove version numbers from

11156 does this now. Include subpipe.h first after config.h, to

11158
11159 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't

11407 When reducing initial empty rules, Bison parser read an initial
11408 location that is not defined. This results in garbage, and that
11409 affects Bison's own parser. Therefore we need (i) to extend Bison

11704 Fix a GLR parser bug I reported in February; see
161a71f3 11705 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.

11706 The problem was that GLR parsers did not conform to the C standard,
11707 because actions like { $1 = $2 + $3; } expanded to expressions
11708 that invoked YYFILL in separate subexpressions, and YYFILL assigned
11709 to a local variable. The C standard says that expressions
11710 like (var = f ()) + (var = f ()) have undefined behavior.
11711 Another problem was that GCC sometimes issues warnings that
11712 yyfill and its parameters are unused.
11713
11714 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
11715 as possibly unused.
11716 (yyfill): New function.
11717 (YYFILL): Use it.
11718 (yyuserAction): Change type of yynormal to bool, so that it matches
11719 the new yyfill signature. Mark it as possibly unused.
11720

11722 Follow up on a bug I reported in February, where a Bison-generated
11723 parser can loop. Provide a test case and a fix for yacc.c. I
11724 don't have a fix for lalr1.cc or for glr.c, unfortunately.
11725 The original bug report is in:

11727
11728 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
11729 macro's size was becoming unwieldy.
11730 (yyerrlab): Do not discard an empty lookahead symbol, as this
11731 might destroy garbage.
11732 (yyerrorlab): New label, with the old contents of YYERROR,
11733 plus the following change: pop the stack of rhs corresponding
11734 to the production that invoked YYERROR. That is how Yacc
11735 behaves, and POSIX requires this behavior.
11736 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
11737 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
11738 Define 'alarm' to do nothing if unistd.h is not available.
11739 Add a new rule "exp: '-' error;" to test the above change to
11740 data/yacc.c. Use 'alarm' to abort any test taking longer than
11741 10 seconds, as it's probably looping.
11742 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
11743 Also, the new yacc.c generates two fewer diagnostics for an
11744 existing test.

12372 we don't need to worry about yyerrlab1 being reported as an

12396 these elements have fake values.

12505 * doc/bison.texinfo (Understanding): Use Yacc style for
12506 conflict reports. Also, use new way of locating rules.
12507 * src/conflicts.c (conflict_report):
12508 Renamed from conflict_report_yacc, removing the old
12509 'conflict_report'. Translate the entire conflict report at once,
12510 so that we don't assume that "," has the same interpretation in
12511 all languages.
12512 (conflicts_output): Use Yacc-style conflict report for each state,
12513 instead of our more-complicated style.
12514 (conflicts_print): Use Yacc-style conflict report, except print
12515 the input file name when not emulating Yacc.
12516 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted

12530 This problem was originally reported by Paul Hilfinger in

12533 * data/yacc.c (yyparse): New local var yylerrsp, to record the
12534 top of the location stack's error locations.
12535 (yyerrlab): Set it. When discarding a token, push its location
12536 onto yylerrsp so that we don't lose track of the error's end.
12537 (yyerrlab1): Now is only the target of YYERROR, so that we can
12538 properly record the location of the action that failed. For GCC
12539 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
12540 GCC warning about yyerrlab1 being unused if YYERROR is unused.
12541 (yyerrlab2): New label, which yyerrlab now falls through to.
12542 Compute the error's location by applying YYLLOC_DEFAULT to
12543 the locations of all the symbols that went into the error.
12544 * doc/bison.texinfo (Location Default Action): Mention that
12545 YYLLOC_DEFAULT is also invoked for syntax errors.
12546 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
12547 Error locations include the locations of all the tokens that were
12548 discarded, not just the last token.

12605 If the user does not define YYSTYPE as a macro, Bison now declares it
12606 using typedef instead of defining it as a macro. POSIX requires this.
12607 For consistency, YYLTYPE is also declared instead of defined.
12608
12609 %union directives can now have a tag before the `{', e.g., the
12610 directive `%union foo {...}' now generates the C code
12611 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
12612 The default union tag is `YYSTYPE', for compatibility with Solaris 9
12613 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
12614 instead of `yyltype'.
12615
12616 `yystype' and `yyltype' are now obsolescent macros instead of being
12617 typedefs or tags; they are no longer documented and will be
12618 withdrawn in a future release.

12626 for backward compatibility.
12627 * data/yacc.c: Likewise.
12628
12629 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
12630 does not specify a union tag. This is for compatibility with
12631 Solaris 9 yacc.
12632
12633 * src/parse-gram.y (add_param): 2nd arg is now char * not char

12650 has (or usually has) an immediately-following braced code.

12652 to return when scanning braced code.

13258 ((...));' if a single statement is desired (e.g. before `else').
13259 Work around GCC warnings by surrounding corresponding calls with

13611 Use new @ escapes consistently. Represent brackets with @{ and @}
13612 rather than @<:@ and @:>@, since this works a bit better with dumb
13613 editors like vi. Represent @ with @@, since @ is now consistently
13614 an escape. Use @oline@ and @ofile@ rather than __oline__ and
13615 __ofile__, to avoid unexpected expansions. Similarly, use @output
13616 rather than #output.
13617
13618 * data/c.m4 (b4_copyright): Omit file name from comment, since
13619 the file name could contain "*/".

13662 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
13663 Use new escapes @{ and @} for [ and ].
13664
13665 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
13666 them with auto vars.
13667 Switch to new escape scheme, where @ is the escape character uniformly.
13668 Abort if a stray escape character is found. Avoid unbounded input
13669 buffer when parsing non-escaped text.

13681 (yygetLRActions, yyrecoverParseError): Use them.

13683 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
13684 counted in the token inserted at end of file. Now takes
13685 location_t *, not location_t, so that the location can be
13686 adjusted. All uses changed.

13694 abort ();'. This reduces the runtime of the "Many lookaheads"

14400 Let nondeterministic skeletons be usable with deterministic
14401 tables.
14402
14403 With the patch, GAWK compiled by GCC without -O2 passes its test
14404 suite using a GLR parser driven by LALR tables. It fails with -O2
14405 because `struct stat' gives two different answers on my machine:
14406 88 (definition of an auto var) and later 96 (memset on this var).
14407 Hence the stack is badly corrumpted. The headers inclusion is to
14408 blame: if I move the awk.h inclusion before GLR's system header
14409 inclusion, the two struct stat have the same size.

14463 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,

14637 signifies end-of-input. Warn about negative chars. Mention
14638 the portable Standard C character set.
14639
14640 The GNU coding standard says CFLAGS and YFLAGS are reserved

14981 to minimize the number of warnings from xgettext.
14982 (handle_action_dollar, handle_action_at): Don't use isdigit,

16930 of composing the error message from different bits.

16949 hard coded 2.
16950 (Even though this 2 is not the same as above: the number of the
16951 undeftoken remains being 2, it is its user token number which
16952 might not be 2).

17715 a conflict with the macro from lib/hash.h).

17817 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).

17854 problems: because Flex includes the headers *before* us,
17855 _GNU_SOURCE is not defined by config.h, and therefore strndup was
17856 not visible.

17873 Include skeleton.h.
17874 Don't use %option yylineno: it seems that then Flex imagines
17875 REJECT has been used, and therefore it won't reallocate its

17877 in warnings for `unused: yy_flex_realloc'.

18183 these states are automatically computed from the initial state.
18184 (generate_states): Adjust.
18185 * src/print.c: When reporting a rule number to the user, substract
18186 1, so that the axiom rule is rule 0, and the first user rule is 1.
18187 * src/reduce.c: Likewise.

18192 0: `$axiom: START-SYMBOL $'.

18194 number of the states has changed (the final state is no longer
18195 necessarily the last), catch up.

18219 (parse_token_decl): If the token being defined has value `0', it
18220 is the eoftoken.
18221 (packsymbols): No longer hack `tags' to insert `$' by hand.
18222 Be sure to preserve the value of the eoftoken.
18223 (reader): Make sure eoftoken is defined.
18224 Initialize nsyms to 0: now eoftoken is created just like the others.
18225 * src/print.c (print_grammar): Don't special case the eof token.
18226 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
18227 lie anyway, albeit pleasant.
18228 * tests/calc.at: Exercise error messages with eoftoken.
18229 Change the grammar so that empty input is invalid.

18321 the switch/case/break flesh.
18322 Don't parse the user action that might follow the guard, let...
18323 (readgram): do it, i.e., now, there can be an action after a

18369 `lookaheadsp' member of the following state (since lookaheads of

18657 * src/print_graph.c (print_core): Complete the set of items via
18658 closure. The next-to-final and final states are still unsatisfying,
18659 but that's to be addressed elsewhere.
18660 No longer output the rule numbers, but do output the state number.
18661 A single loop for the shifts + gotos is enough, but picked a

19070 Because useless nonterminals are now kept alive (instead of being

19079 the number of occurrences of each symbol, and later reassigned to
19080 `shift_symbol', containing the symbol that can be shifted from a
19081 given state.
19082 Deobfuscate, i.e., allocate, use and free `symbol_count' here
19083 only, and...

19670 use abs. path to find config.h.
19671 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

21466 The location tracking mechanism is precious for parse error
21467 messages. Nevertheless, it is enabled only when `@n' is used in
21468 the grammar, which is a different issue (you can use it in error

21470 be another means to enable it.

21502 Test also `--verbose', `--defines' and `--name-prefix'. Testing
21503 the latter demonstrates a flaw in the handling of non debugging
21504 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
21505 was used in order to simplify:
21506
21507 #if YYDEBUG
21508 if (yydebug)
21509 {
21510 ...

21512 #endif
21513
21514 into
21515
21516 if (yydebug)
21517 {
21518 ...
21519 }
21520
21521 unfortunately this leads to a CPP conflict when
21522 `--name-prefix=foo' is used since it produces `#define yydebug
21523 foodebug'.

21573 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
21574 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
21575 difficult and introduced a lot of core dump. It turns out that
21576 Bison used an implementation of `xmalloc' based on `calloc', and
21577 at various places it does depend upon the initialization to 0. I
21578 have not tried to isolate the pertinent places, and all the former
21579 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,

22663 New function.
22664 (readgram): Use `#if 0' around code that accepted %command
22665 inside grammar rules: The documentation doesn't allow it,

22667 (parse_token_decl): Extended the %token
22668 declaration to allow a multi-character symbol as an alias.
22669 (parse_thong_decl): New function.
22670 (read_declarations): Added %thong declarations.

22680 Revised and use multiple warnxxx functions to avoid using VARARGS1.
22681 (read_declarations): Improve the error message for
22682 an invalid character. Do not abort.
22683 (read_declarations, copy_guard, copy_action): Use
22684 printable_version to avoid unprintable characters in printed output.
22685 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
22686 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):

22691 (output_headers, output_trailers, output, output_gram)
22692 (output_rule_data): Implement noparserflag variable.

22701
22702 * src/lex.h:
22703 Added THONG and NOOP for alias processing.

22707 Include getopt.h. Add some extern decls.
22708 (safegetc): New function to deal with EOF gracefully.
22709 (literalchar); new function to deal with reading \ escapes.
22710 (lex): Use literalchar.
22711 (lex): Implemented "..." tokens.
22712 (literalchar, lex, parse_percent_token): Made tokenbuffer
22713 always contain the token. This includes growing the token
22714 buffer while reading an integer.
22715 (parse_percent_token): Replaced if-else statement with percent_table.
22716 (parse_percent_token): Added % declarations as another
22717 way to specify the flags -n, -l, and -r. Also added hooks for
22718 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
22719 major changes to files.c.
22720 (lex) Retain in the incoming stream a character following
22721 an incorrect '/'.
22722 (skip_white_space, lex): Revised most error messages
22723 and changed fatal to warn to avoid aborting.
22724 (percent_table): Added %thong declarations.
