41 Extract the parsing of user actions from the grammar scanner.
42 As a consequence, the relation between the grammar scanner and
43 parser is much simpler. We can also split "composite tokens" back
44 into simple tokens.
45 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
46 * src/scan-gram.l (add_column_width, adjust_location): Move to and
47 rename as...
48 * src/location.h, src/location.c (add_column_width)
49 (location_compute): these.
50 Fix the column count: the initial column is 0.
51 (location_print): Be robust to ending column being 0.
52 * src/location.h (boundary_set): New.
53 * src/main.c: Adjust to scanner_free being renamed as
54 gram_scanner_free.
55 * src/output.c: Include scan-code.h.
56 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
57 Use boundary_set.
58 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
59 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
60 which is now, again, a separate token.
61 Adjust all dependencies.
62 Whereever actions with $ and @ are used, use translate_code.
63 (action): Remove this nonterminal which is now useless.
64 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
65 (grammar_current_rule_action_append): Use translate_code.
66 (packgram): Bound check ruleno, itemno, and rule_length.
67 * src/reader.h (gram_in, gram__flex_debug, scanner_cursor)
68 (last_string, last_braced_code_loc, max_left_semantic_context)
69 (scanner_initialize, scanner_free, scanner_last_string_free)
70 (gram_out, gram_lineno, YY_DECL_): Move to...
71 * src/scan-gram.h: this new file.
72 (YY_DECL): Rename as...
73 (GRAM_DECL): this.
74 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
75 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
76 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
77 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
78 Move these declarations, and...
79 (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
80 these to...
81 * src/flex-scanner.h: this new file.
82 * src/scan-gram.l (rule_length, rule_length_overflow)
83 (increment_rule_length): Remove.
84 (last_braced_code_loc): Rename as...
85 (gram_last_braced_code_loc): this.
86 Adjust to the changes of the parser.
87 Move all the handling of $ and @ into...
88 * src/scan-code.l: here.
89 * src/scan-gram.l (handle_dollar, handle_at): Remove.
90 (handle_action_dollar, handle_action_at): Move to...
91 * src/scan-code.l: here.
92 * src/Makefile.am (bison_SOURCES): Add flex-scanner.h,
93 scan-code.h, scan-code-c.c, scan-gram.h.
94 (EXTRA_bison_SOURCES): Add scan-code.l.
95 (BUILT_SOURCES): Add scan-code.c.
96 (yacc): Be robust to white spaces.
97
98 * tests/conflicts.at, tests/input.at, tests/reduce.at,

110 Between Bison releases, manually append `+' to the previous Bison
111 release number, and use that as a signal to automatically print the
112 ChangeLog's CVS Id keyword from --version. Discussed starting at
113 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
114 * ChangeLog: Add Id header.
115 * configure.ac (AC_INIT): Append `+' to `2.3'.
116 * src/.cvsignore: Add revision.c.
117 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
118 (BUILT_SOURCES): Add revision.c.
119 (revision.c): New target rule. This file defines a new global variable
120 named revision. It initializes it with either the Id from ChangeLog
121 or, if VERSION doesn't contain `+', with the empty string.
122 * src/getargs.c (version): Print the value of revision.

162 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
163 shell, not within 'make', so that 'make' by an ordinary builder
164 (using GNU make) does not worry about configuring gzip. This also
165 works around a bug reported independently by Keith Thompson and by
166 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
167 stderr rather than stdout, messing up the build logs.

171 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
172 to make sure that YYID will never be unused. This fixes a 'make
173 maintainer-check' failure caused by the recent changes to the 'Trivial
174 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
175 not used.
176 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.

180 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
181 state before an empty RHS is always resolved here. Only the location
182 of that state is guaranteed to be resolved, and that's enough. This
183 fixes the remaining bug reported by Derek M. Jones in
184 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
185 * tests/glr-regression.at (Uninitialized location when reporting
186 ambiguity): Test the above case.
187 Also, the embedded comments in this test case claim it checks the case
188 of an empty RHS that has inherited the initial location. However, the
189 corresponding LHS was already resolved, so yyresolveLocations didn't
190 actually have reason to modify it. Fix this by forcing
191 nondeterministic operation at the beginning of the parse.

196 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
197 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
198 of the bugs reported today by Derek M Jones in
199 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
200 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
201 defined to be a type name without parens or brackets.
202 (Location Type): Similarly for YYLTYPE.
203 * tests/regression.at (Trivial grammars): Put in a test for this
204 bug that will be caught by 'make maintainer-check' (though not,
205 alas, by 'make check' unless your compiler is picky).

1664 Use unlocked I/O for a minor performance improvement on hosts like
1665 GNU/Linux and Solaris that support unlocked I/O. The basic idea

2002 * doc/bison.texinfo: Don't use "filename", as per GNU coding
2003 standards. Use "file name" or "file" or "name", depending on
2004 the context.
2005 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
2006 not to hack/foo.tab.c.
2007 (Calc++ Top Level): 2nd arg of main is not const.

2113 AT_PARSER_CHECK for data that contains backslashes. It currently
2114 uses 'echo', and 'echo' isn't portable if its argument contains
2115 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
2116 that the byte '\0xff' is not printable in the C locale; it is,
2117 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
2118 not printable, so use '\0x81' to test.

2156 (signatures, %.asc): Remove.
2157 (rel-files, announcement): Remove signatures.
2158 Restore old updating code, even though we don't use it, so
2159 that we're the same as coreutils.

2173 we comment out the Autoconf version number.
2174 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
2175 it's error-prone and "make maintainer-distcheck" rejects it.
2176
2177 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
2178 Indent calls to "error" to pacify "make maintainer-distcheck",

2196 void, to avoid warning when NLS is disabled.
2197 * src/output.c: Include scan-skel.h.
2198 (scan_skel): Remove decl, since scan-skel.h does this.
2199 (output_skeleton):
2200 Indent calls to "error" to pacify "make maintainer-distcheck".
2201 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
2202 * src/reader.h (gram_end, gram_lineno): New decls to pacify
2203 "make maintainer-distcheck".
2204 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):

2210 Indent calls to "error" to pacify "make maintainer-distcheck".

2212 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
2213 not @VAR@.

2215 * tests/torture.at: Revamp to avoid misuse of atoi that
2216 "make maintainer-distcheck" complained about.
2217
2218 * examples/extexi (message): Don't print a message more than once,
2219 and omit line-number decoration that makes Emacs compile think
2220 that informative messages are worth worrying about.
2221

2227 accidentally.
2228 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
2229 autogenerated by the maintainer.
2230 * examples/calc++/.cvsignore: Add *.yy.
2231
2232 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.

2240

2242 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
2243
2244 * bootstrap: For translations that have not yet been upgraded to
2245 the new runtime-po domain, prime the pump by extracting the
2246 relevant strings from the obsolete translations. This code can be
2247 removed once the bison-runtime domain has been translated by each
2248 team.
2249
2250 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
2251 now that token names are already quoted.

2267 (yyreportSyntaxError): Use it to dequote most string literals.

2274 * doc/bison.texinfo (Decl Summary, Calling Convention):
2275 Clarify quoting convention of yytname.
2276 * src/output.c (prepare_symbols): Quote all names. This undoes
2277 the 2005-04-17 change, which is now accomplished (mostly) via
2278 changes in the parsers as described above.
2279 * tests/regression.at (Token definitions, Web2c Actions):
2280 Undo most 2005-04-17 change here, too.

22822005-07-20 Paul Eggert <eggert@cs.ucla.edu>
2283
2284 Fix more problems reported by twlevo@xs4all.nl.
2285 * tests/cxx-type.at: Don't pipe output of ./types through sed to
2286 remove trailing spaces. This loses the exit status of ./types,
2287 and isn't needed since ./types shouldn't be emitting trailing
2288 spaces.
2289 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
2290 as the stack isn't valid in that case.
2291
2292 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
2293 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
2294 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):

2296 is used.
2297 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):

2303 overly-picky compilers that reject 'char *foo = "bar";'.
2304
2305 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
2306 to FILE * parameter, not to stderr. This fixes a typo introduced
2307 in the 2005-07-12 change.
2308
2309 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
2310 warnings from GCC 4.

2321 Destructor cleanups and regularization among the three skeletons.
2322 * NEWS: Document the behavior changes.
2323 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
2324 stack before failing, as the cleanup code will do it for us now.
2325 * data/lalr1.cc (yyerrlab): Likewise.
2326 * data/glr.c (yyparse): Pop everything off the stack before
2327 freeing it, so that destructors get called properly.

2329 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
2330 This is more consistent.

2347 Rename yyoverflowab to yyexhaustedlab.
2348 When memory exhaustion occurs during syntax-error reporting,
2349 report it separately rather than in a single diagnostic; this
2350 eases translation.

2358 Add i18n support to the GLR skeleton. Partially fix the C++
2359 skeleton; a C++ expert needs to finish this. Remove debugging
2360 msgids; there's little point to having them translated, since they
2361 can be understood only by someone who can read the
2362 (English-language) source code.
2363
2364 Generate runtime-po/bison-runtime.pot automatically, so that we
2365 don't have to worry about garbage getting in that file. We'll
2366 make sure after the next official release that old msgids don't
2367 get lost. See
2368 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
2369
2370 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
2371 Now auto-generated.
2372 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
2373 Fix typos in explanations of the runtime file.
2374 * bootstrap: Change gettext keyword from YYI18N to YY_.
2375 Use standard Makefile.in.in in runtime-po, since we'll arrange
2376 for backward-compatible bison-runtime.po files in a different way.
2377 * data/glr.c (YY_): New macro, from yacc.c.
2378 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
2379 Translate messages intended for users.
2380 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
2381 the wording in the other skeletons. We don't know that the memory
2382 is virtual.
2383 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
2384 Use same method that yacc.c uses.
2385 Don't translate debugging messages.
2386 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
2387 it doesn't work (yet), and requires C++ expertise to fix.

3142 Returning a bool introduces a problem: 0 corresponds to false, and
3143 it seems weird to return false on success. Returning true changes
3144 the conventions for yyparse.

3191 Remove uses of 'short int' and 'unsigned short int'. This raises
3192 some arbitrary limits. It uses more memory but nowadays that's
3193 not much of an issue.

3195 This change does not affect the generated parsers; that's a different
3196 task, as some users will want to conserve memory there.

3198 Ideally we should use size_t to represent all object counts, and

3599 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
3600 whether the reducion was empty or not. This leaves room to
3601 improve the use of YYLLOC_DEFAULT in such a case.
3602 lalr1.cc is still experimental, so changing this is acceptable.
3603 And finally, there are probably not many users who changed the
3604 handling of locations in GLR, so changing is admissible too.

3752 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
3753 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
3754 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
3755 the extra Bison directives instead of the whole series.
3756 Change the grammar so that there are recoverable errors, and
3757 unrecoverable errors. Now we can have the parser give up before
3758 consuming the whole input. As a result we now can observe that
3759 the lookahead is freed when needed.
3760 Change the parser source to parse argv[1] instead of a hard coded
3761 string.
3762 Simplify yylex, and give a value and location to EOF.
3763 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
3764 passed directives already coded in the file.
3765 Add some tests to check the location of "error".
3766 For some tests, the C++ parser is correct, and not yacc.c.
3767 For other tests, they provide different, but unsatisfying, values,
3768 so keep the C++ value so that at least one parser is "correct"
3769 according to the test suite.
3770 (Actions after errors): Remove, this is subsumed by the
3771 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

3949 Spent a few hours checking out which prerequisite versions the
3950 current sources actually require. I went all the way back to
3951 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
3952 a seemingly endless set of combinations of versions more recent
3953 than that. The bottom line is that the current sources require
3954 fairly recent versions of the build tools, and it'll be some work
3955 to change this.
3956 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
3957 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
3958 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
3959 Add comments explaining why those particular versions are
3960 currently needed.

4471 When reducing initial empty rules, Bison parser read an initial
4472 location that is not defined. This results in garbage, and that

4768 Fix a GLR parser bug I reported in February; see

4770 The problem was that GLR parsers did not conform to the C standard,
4771 because actions like { $1 = $2 + $3; } expanded to expressions
4772 that invoked YYFILL in separate subexpressions, and YYFILL assigned
4773 to a local variable. The C standard says that expressions
4774 like (var = f ()) + (var = f ()) have undefined behavior.
4775 Another problem was that GCC sometimes issues warnings that
4776 yyfill and its parameters are unused.
4777
4778 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
4779 as possibly unused.
4780 (yyfill): New function.
4781 (YYFILL): Use it.
4782 (yyuserAction): Change type of yynormal to bool, so that it matches
4783 the new yyfill signature. Mark it as possibly unused.

4786 Follow up on a bug I reported in February, where a Bison-generated
4787 parser can loop. Provide a test case and a fix for yacc.c. I

4789 The original bug report is in:

4791
4792 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
4793 macro's size was becoming unwieldy.
4794 (yyerrlab): Do not discard an empty lookahead symbol, as this
4795 might destroy garbage.
4796 (yyerrorlab): New label, with the old contents of YYERROR,
4797 plus the following change: pop the stack of rhs corresponding
4798 to the production that invoked YYERROR. That is how Yacc
4799 behaves, and POSIX requires this behavior.
4800 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
4801 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
4802 Define 'alarm' to do nothing if unistd.h is not available.
4803 Add a new rule "exp: '-' error;" to test the above change to
4804 data/yacc.c. Use 'alarm' to abort any test taking longer than
4805 10 seconds, as it's probably looping.
4806 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
4807 Also, the new yacc.c generates two fewer diagnostics for an
4808 existing test.

5435 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
5436 we don't need to worry about yyerrlab1 being reported as an
5437 "unused label" by non-GCC C compilers. The downside is that if
5438 locations are used then a couple of statements are duplicated each
5439 time YYERROR is invoked, but the upside is that the warnings
5440 should vanish.
5441 (yyerrlab1): Move code to YERROR.

5458 popped). This means that the initial elements will not be freed
5459 explicitly, as is the case in yacc.c; it is not a problem, as
5460 these elements have fake values.

5569 * doc/bison.texinfo (Understanding): Use Yacc style for
5570 conflict reports. Also, use new way of locating rules.
5571 * src/conflicts.c (conflict_report):
5572 Renamed from conflict_report_yacc, removing the old
5573 'conflict_report'. Translate the entire conflict report at once,
5574 so that we don't assume that "," has the same interpretation in
5575 all languages.
5576 (conflicts_output): Use Yacc-style conflict report for each state,
5577 instead of our more-complicated style.
5578 (conflicts_print): Use Yacc-style conflict report, except print
5579 the input file name when not emulating Yacc.
5580 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted

5597 * data/yacc.c (yyparse): New local var yylerrsp, to record the
5598 top of the location stack's error locations.
5599 (yyerrlab): Set it. When discarding a token, push its location
5600 onto yylerrsp so that we don't lose track of the error's end.
5601 (yyerrlab1): Now is only the target of YYERROR, so that we can
5602 properly record the location of the action that failed. For GCC
5603 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
5604 GCC warning about yyerrlab1 being unused if YYERROR is unused.
5605 (yyerrlab2): New label, which yyerrlab now falls through to.
5606 Compute the error's location by applying YYLLOC_DEFAULT to
5607 the locations of all the symbols that went into the error.
5608 * doc/bison.texinfo (Location Default Action): Mention that
5609 YYLLOC_DEFAULT is also invoked for syntax errors.
5610 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

5669 If the user does not define YYSTYPE as a macro, Bison now declares it
5670 using typedef instead of defining it as a macro. POSIX requires this.
5671 For consistency, YYLTYPE is also declared instead of defined.
5672
5673 %union directives can now have a tag before the `{', e.g., the
5674 directive `%union foo {...}' now generates the C code
5675 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
5676 The default union tag is `YYSTYPE', for compatibility with Solaris 9
5677 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
5678 instead of `yyltype'.
5679
5680 `yystype' and `yyltype' are now obsolescent macros instead of being
5681 typedefs or tags; they are no longer documented and will be

5691 * data/yacc.c: Likewise.
5692

5694 does not specify a union tag. This is for compatibility with
5695 Solaris 9 yacc.

5714 has (or usually has) an immediately-following braced code.

5716 to return when scanning braced code.

6675 Use new @ escapes consistently. Represent brackets with @{ and @}
6676 rather than @<:@ and @:>@, since this works a bit better with dumb
6677 editors like vi. Represent @ with @@, since @ is now consistently
6678 an escape. Use @oline@ and @ofile@ rather than __oline__ and
6679 __ofile__, to avoid unexpected expansions. Similarly, use @output
6680 rather than #output.
6681
6682 * data/c.m4 (b4_copyright): Omit file name from comment, since
6683 the file name could contain "*/".
6684 (b4_synclines_flag): Don't quote the 2nd argument; it should already
6685 be quoted. All uses changed.

6699 mishandled funny characters in file names, and anyway it isn't
6700 needed any more.
6701 * data/yacc.c: Likewise.

6725 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
6726 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
6727 Use new escapes @{ and @} for [ and ].
6728
6729 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
6730 them with auto vars.
6731 Switch to new escape scheme, where @ is the escape character uniformly.
6732 Abort if a stray escape character is found. Avoid unbounded input
6733 buffer when parsing non-escaped text.

6744 table.
6745 (yygetLRActions, yyrecoverParseError): Use them.
6746
6747 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
6748 counted in the token inserted at end of file. Now takes
6749 location_t *, not location_t, so that the location can be
6750 adjusted. All uses changed.

6757 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))

6770
6771 Remove nounput option. At an unexpected end of file, we now unput

7087 The last OS that we could find where this wouldn't work is
7088 SunOS 3.5, and that's too old to worry about now.
7089

7136 * src/getargs.c (usage): Likewise.
7137

7139 the last one. When there are too many, report the first extra

7153 for a freestanding C89 compiler.

7464 Let nondeterministic skeletons be usable with deterministic
7465 tables.
7466
7467 With the patch, GAWK compiled by GCC without -O2 passes its test
7468 suite using a GLR parser driven by LALR tables. It fails with -O2
7469 because `struct stat' gives two different answers on my machine:
7470 88 (definition of an auto var) and later 96 (memset on this var).
7471 Hence the stack is badly corrumpted. The headers inclusion is to
7472 blame: if I move the awk.h inclusion before GLR's system header
7473 inclusion, the two struct stat have the same size.

8045 to minimize the number of warnings from xgettext.
8046 (handle_action_dollar, handle_action_at): Don't use isdigit,
8047 as it mishandles negative chars and it may not work as expected
8048 outside the C locale.
8049
8050 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
8051 this is a GCC extension and is not portable to other compilers.

8054 Do not include <ctype.h>; no longer needed.

8059 it's not portable.
8060
8061 * tests/regression.at: Do not use 'cc -c input.c -o input';

8065 exit status as failure, not just exit status 1. Sun C exits
8066 with status 2 sometimes.

10941 in warnings for `unused: yy_flex_realloc'.

12134 Because useless nonterminals are now kept alive (instead of being
12135 `destroyed'), we now sometimes examine them, and store information
12136 related to them. Hence we need to know their number, and adjust
12137 memory allocations.

12139 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
12140 static.
12141 * src/LR0.c (allocate_itemsets): The memory allocated to
12142 `symbol_count' was used for two different purpose: once to count
12143 the number of occurrences of each symbol, and later reassigned to
12144 `shift_symbol', containing the symbol that can be shifted from a
12145 given state.
12146 Deobfuscate, i.e., allocate, use and free `symbol_count' here
12147 only, and...
12148 (new_itemsets): Allocate `shift_symbol' here.
12149 (allocate_itemsets): symbol_count includes useless nonterminals.
12150 Make room for them.
12151 (free_storage): Use `free', not `XFREE', for pointers that cannot
12152 be null.

12298 faster and reduces fragmentation.

14116 making this decision. This is the only way out for portability
14117 issues in Bison, it would mean way too much duplicate effort to
14118 import in Bison features implemented in 2.49c since 2.13.
14119 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

14530 The location tracking mechanism is precious for parse error
14531 messages. Nevertheless, it is enabled only when `@n' is used in
14532 the grammar, which is a different issue (you can use it in error
14533 message, but not in the grammar per se). Therefore, there should
14534 be another means to enable it.

14566 Test also `--verbose', `--defines' and `--name-prefix'. Testing
14567 the latter demonstrates a flaw in the handling of non debugging
14568 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
14569 was used in order to simplify:
14570
14571 #if YYDEBUG
14572 if (yydebug)
14573 {
14574 ...
14575 }
14576 #endif
14577
14578 into
14579
14580 if (yydebug)
14581 {
14582 ...
14583 }
14584
14585 unfortunately this leads to a CPP conflict when
14586 `--name-prefix=foo' is used since it produces `#define yydebug
14587 foodebug'.
14588
14589 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.

14637 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
14638 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
14639 difficult and introduced a lot of core dump. It turns out that
14640 Bison used an implementation of `xmalloc' based on `calloc', and
14641 at various places it does depend upon the initialization to 0. I
14642 have not tried to isolate the pertinent places, and all the former
14643 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
14644 someone should address this issue.

15016 of the lhs of the rule (by default ranging from the location of
