67 UNION-FLAG. All callers changed.
68 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.

147 Spent a few hours checking out which prerequisite versions the
148 current sources actually require. I went all the way back to
149 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
150 a seemingly endless set of combinations of versions more recent
151 than that. The bottom line is that the current sources require
152 fairly recent versions of the build tools, and it'll be some work
153 to change this.
154 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
155 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
156 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
157 Add comments explaining why those particular versions are
158 currently needed.

163
164 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
165 (it fails with a Autoconf-without-aclocal-m4 diagnostic).

192 Undo change made earlier today: it caused autopoint to not bring
193 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
194 autopoint's.
195
196 * bootstrap: Check that gettext version matches what's in
197 configure.ac. Warn users to ignore robots.txt ERROR 404.
198 * bootstrap: Undo today's earlier change (logged below).

238 supported by GCC 3.4.0.

286 on them being in our CVS. Upgrade to latest versions of gnulib
287 and Automake.
288
289 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
290 * bootstrap: Bootstrap from gnulib and po repositories.
291 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
292 * README-cvs: Document these changes. Remove version numbers from
293 mentions of build tools, since they change so often. Mention Flex.

305 by the Yacc library and must port to K&R hosts.
306 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.

323 for us.
324 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
325 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
326
327 * src/files.c: Include gnulib's xstrndup.h.
328
329 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.

423 unused declaration.

669 When reducing initial empty rules, Bison parser read an initial

966 Fix a GLR parser bug I reported in February; see
967 <http://mail.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
968 The problem was that GLR parsers did not conform to the C standard,
969 because actions like { $1 = $2 + $3; } expanded to expressions
970 that invoked YYFILL in separate subexpressions, and YYFILL assigned
971 to a local variable. The C standard says that expressions
972 like (var = f ()) + (var = f ()) have undefined behavior.
973 Another problem was that GCC sometimes issues warnings that
974 yyfill and its parameters are unused.
975
976 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
977 as possibly unused.
978 (yyfill): New function.
979 (YYFILL): Use it.
980 (yyuserAction): Change type of yynormal to bool, so that it matches
981 the new yyfill signature. Mark it as possibly unused.
982
983
984 Follow up on a bug I reported in February, where a Bison-generated
985 parser can loop. Provide a test case and a fix for yacc.c. I
986 don't have a fix for lalr1.cc or for glr.c, unfortunately.
987 The original bug report is in:
988 <http://mail.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
989
990 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
991 macro's size was becoming unwieldy.
992 (yyerrlab): Do not discard an empty lookahead symbol, as this
993 might destroy garbage.
994 (yyerrorlab): New label, with the old contents of YYERROR,
995 plus the following change: pop the stack of rhs corresponding
996 to the production that invoked YYERROR. That is how Yacc
997 behaves, and POSIX requires this behavior.
998 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
999 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
1000 Define 'alarm' to do nothing if unistd.h is not available.
1001 Add a new rule "exp: '-' error;" to test the above change to
1002 data/yacc.c. Use 'alarm' to abort any test taking longer than
1003 10 seconds, as it's probably looping.
1004 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
1005 Also, the new yacc.c generates two fewer diagnostics for an
1006 existing test.

1168 Declare to be of type suitable for the ninf value itself, not of
1169 type suitable for the corresponding table, since the latter might
1170 be unsigned but the ninf value might be negative. This fixes a

1634 we don't need to worry about yyerrlab1 being reported as an
1635 "unused label" by non-GCC C compilers. The downside is that if
1636 locations are used then a couple of statements are duplicated each
1637 time YYERROR is invoked, but the upside is that the warnings
1638 should vanish.

1654 when the stacks contain one element, as the loop would otherwise
1655 free the last state, and then use the top state (the one we just
1656 popped). This means that the initial elements will not be freed
1657 explicitly, as is the case in yacc.c; it is not a problem, as
1658 these elements have fake values.

1771 'conflict_report'. Translate the entire conflict report at once,
1772 so that we don't assume that "," has the same interpretation in
1773 all languages.
1774 (conflicts_output): Use Yacc-style conflict report for each state,
1775 instead of our more-complicated style.
1776 (conflicts_print): Use Yacc-style conflict report, except print
1777 the input file name when not emulating Yacc.
1778 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
1779 Conflicted Reduction, %expect not enough, %expect too much,

1797 (yyerrlab): Set it. When discarding a token, push its location
1798 onto yylerrsp so that we don't lose track of the error's end.
1799 (yyerrlab1): Now is only the target of YYERROR, so that we can
1800 properly record the location of the action that failed. For GCC
1801 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
1802 GCC warning about yyerrlab1 being unused if YYERROR is unused.
1803 (yyerrlab2): New label, which yyerrlab now falls through to.
1804 Compute the error's location by applying YYLLOC_DEFAULT to
1805 the locations of all the symbols that went into the error.
1806 * doc/bison.texinfo (Location Default Action): Mention that
1807 YYLLOC_DEFAULT is also invoked for syntax errors.
1808 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

1867 If the user does not define YYSTYPE as a macro, Bison now declares it
1868 using typedef instead of defining it as a macro. POSIX requires this.
1869 For consistency, YYLTYPE is also declared instead of defined.
1870
1871 %union directives can now have a tag before the `{', e.g., the
1872 directive `%union foo {...}' now generates the C code
1873 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
1874 The default union tag is `YYSTYPE', for compatibility with Solaris 9
1875 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
1876 instead of `yyltype'.
1877
1878 `yystype' and `yyltype' are now obsolescent macros instead of being
1879 typedefs or tags; they are no longer documented and will be

1889 * data/yacc.c: Likewise.
1890

1893 Solaris 9 yacc.

1944 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
1945 as the caller now does that.

1947 (YYEMPTY): Parenthesize right hand side, since others use it.
1948 (yyparse): Don't assume that our generated code is the only code
1949 that sets yychar.

1983
1984 Remove unportable casts and storage allocation tricks.
1985 While we're at it, remove almost all casts, since they
1986 usually aren't needed and are a sign of trouble.
1987
1988 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
1989
1990 * src/derives.c (derives_compute): Do not subtract NTOKENS from
1991 the pointer DSET returned by malloc; this isn't portable.
1992 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
1993 Similarly for DERIVES.
1994 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
1995 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
1996 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
1997
1998 * src/derives.c (derives_compute): Do not bother invoking
1999 int_of_rule_number, since rule numbers are integers.
2000
2001 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
2002 rather than XMALLOC (char, N).
2003

2005
2006 * src/gram.h (symbol_number_as_item_number,
2007 item_number_as_symbol_number, rule_number_as_item_number,
2008 item_number_as_rule_number):
2009 Now inline functions rather than macros, to avoid casts.
2010 * src/state.h (state_number_as_int): Likewise.
2011 * src/tables.c (state_number_to_vector_number,
2012 symbol_number_to_vector_number): Likewise.

2015
2016 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
2017 since the resulting storage is always stored into.
2018
2019 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
2020 where it's needed.
2021
2022 * src/muscle_tab.c (muscle_m4_output):
2023 Now inline. Return bool, not int.
2024 * src/state.c (state_compare): Likewise.

2036 hash_symbol_hasher): Likewise.
2037 * src/uniqstr.c (uniqstr_print_processor): Likewise.
2038 * src/muscle_tab.c (muscles_m4_output):
2039 Use new functions instead of casting old functions unportably.
2040 * src/state.c (state_hash_new): Likewise.
2041 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
2042 symbols_token_translations_init):
2043 Likewise.
2044 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
2045
2046 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
2047 var instead of casting to long, to avoid casts.
2048 (prepare_states): Use MALLOC rather than alloca, so that we don't
2049 have to worry about alloca.
2050 * src/state.c (state_hash_lookup): Likewise.
2051
2052 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
2053 local var instead of casting to unsigned char, to avoid casts.

2056 STATE_ALLOC): Remove.
2057 (transitions_new, errs_new, reductions_new, state_new): Use malloc
2058 rather than calloc, and use offsetof to avoid allocating slightly
2059 too much storage.
2060 (state_new): Initialize all members.
2061
2062 * src/state.c (state_hash): Use unsigned accumulator, not signed.
2063
2064 * src/symtab.c (symbol_free): Remove; unused.
2065 (symbol_get): Remove cast in lhs of assignment.

2070 (symbol_processor): Remove.
2071 (symbols_do): Remove decl; now static.

2075 (<inttypes.>, <stdint.h>): Include if available.
2076 (uintptr_t): New type, if system lacks it.
2077 (CALLOC, MALLOC, REALLOC): New macros.

2082 (table_grow, table_ninf_remap): Use signed table size.

2096 Change identifier spellings to avoid collisions with names
2097 that are reserved by POSIX.
2098
2099 Don't use names ending in _t, since POSIX reserves them.
2100 For consistency, remove _e and _s endings -- they're weren't
2101 needed to remove ambiguity. All uses changed.

2103 turn was just renamed from struniq_t.

2244 then the . include files in double-quotes (alphabetized). Fix
2245 dependency breakages encountered in this process, as follows:

2305 All callers changed.

2319 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.

2873 Use new @ escapes consistently. Represent brackets with @{ and @}
2874 rather than @<:@ and @:>@, since this works a bit better with dumb
2875 editors like vi. Represent @ with @@, since @ is now consistently
2876 an escape. Use @oline@ and @ofile@ rather than __oline__ and
2877 __ofile__, to avoid unexpected expansions. Similarly, use @output
2878 rather than #output.
2879

2928 them with auto vars.
2929 Switch to new escape scheme, where @ is the escape character uniformly.
2930 Abort if a stray escape character is found. Avoid unbounded input
2931 buffer when parsing non-escaped text.

2946 counted in the token inserted at end of file. Now takes
2947 location_t *, not location_t, so that the location can be

3172 Check for overflow here.
3173 Allow \? and UCNs, for compatibility with C.

3176 with quote slot used by complain_at.

3179 in symbols, long literals, and funny escapes in strings.

3217 indicates one.
3218 * src/output.c (output_skeleton): Use xfclose rather than fclose

3283 decl; not needed any more.
3284 * src/main.c (main): Use return to exit, undoing yesterday's change.
3285 The last OS that we could find where this wouldn't work is
3286 SunOS 3.5, and that's too old to worry about now.
3287
3288 * data/glr.c (struct yyltype): Define members even when not
3289 doing locations. This is more consistent with yacc.c, and it
3290 works around the following bug reports:

3304 Be consistent about 'bool'; the old code used an enum in one

3307 * configure.ac (AC_HEADER_STDBOOL): Add.

3331 What was that "2" for?
3332
3333 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
3334 * src/getargs.c (usage): Likewise.
3335
3336 * src/getargs.c (getargs): When there are too few operands, report
3337 the last one. When there are too many, report the first extra
3338 one. This is how diffutils does it.

3350 Include <limits.h> unconditionally, since it's guaranteeed even
3351 for a freestanding C89 compiler.

3527 Stop using the "enum_" trick for K&R-style function definitions;
3528 it confused me, and I was the author! Instead, assume that people

3662 Let nondeterministic skeletons be usable with deterministic
3663 tables.
3664
3665 With the patch, GAWK compiled by GCC without -O2 passes its test
3666 suite using a GLR parser driven by LALR tables. It fails with -O2
3667 because `struct stat' gives two different answers on my machine:
3668 88 (definition of an auto var) and later 96 (memset on this var).
3669 Hence the stack is badly corrumpted. The headers inclusion is to
3670 blame: if I move the awk.h inclusion before GLR's system header
3671 inclusion, the two struct stat have the same size.

3725 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,

3728 * src/scan-gram.l (rule_length): New static var.
3729 Use it to keep track of the rule length in the scanner, since
3730 we can't expect the parser to be in lock-step sync with the scanner.

3900 the portable Standard C character set.
3901
3902 The GNU coding standard says CFLAGS and YFLAGS are reserved
3903 for the installer to set.

4240 to void, to avoid a GCC warning when --disable-nls is in effect.
4241
4242 * src/scan-gram.l: Use strings rather than escapes when possible,
4243 to minimize the number of warnings from xgettext.
4244 (handle_action_dollar, handle_action_at): Don't use isdigit,
4245 as it mishandles negative chars and it may not work as expected
4246 outside the C locale.
4247
4248 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
4249 this is a GCC extension and is not portable to other compilers.

7116 problems: because Flex includes the headers *before* us,
7117 _GNU_SOURCE is not defined by config.h, and therefore strndup was
7118 not visible.

7136 Don't use %option yylineno: it seems that then Flex imagines
7137 REJECT has been used, and therefore it won't reallocate its
7138 buffers (which makes no other sense to me than a bug). It results
7139 in warnings for `unused: yy_flex_realloc'.

7446 (generate_states): Adjust.
7447 * src/print.c: When reporting a rule number to the user, substract
7448 1, so that the axiom rule is rule 0, and the first user rule is 1.

7484 Be sure to preserve the value of the eoftoken.
7485 (reader): Make sure eoftoken is defined.
7486 Initialize nsyms to 0: now eoftoken is created just like the others.
7487 * src/print.c (print_grammar): Don't special case the eof token.
7488 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
7489 lie anyway, albeit pleasant.
7490 * tests/calc.at: Exercise error messages with eoftoken.
7491 Change the grammar so that empty input is invalid.

7584 Don't parse the user action that might follow the guard, let...

7631 `lookaheadsp' member of the following state (since lookaheads of

8490 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
8491 an arbitrary restriction on hosts where size_t is wider than int.
8492
8493 (yyparse): Don't dump core if alloca or malloc fails; instead, report
8494 a parser stack overflow. Allocate just one block of memory for all
8495 three stacks, instead of allocating three blocks; this typically is
8496 faster and reduces fragmentation.
8497
8498 Do not limit the number of items in the stack to a value that fits
8499 in 'int', as this is an arbitrary limit on hosts with 64-bit
8500 size_t and 32-bit int.

10728 The location tracking mechanism is precious for parse error

10764 Test also `--verbose', `--defines' and `--name-prefix'. Testing
10765 the latter demonstrates a flaw in the handling of non debugging
10766 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
10767 was used in order to simplify:
10768
10769 #if YYDEBUG

10778 if (yydebug)
10779 {
10780 ...
10781 }

10835 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
10836 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
10837 difficult and introduced a lot of core dump. It turns out that
10838 Bison used an implementation of `xmalloc' based on `calloc', and
10839 at various places it does depend upon the initialization to 0. I
10840 have not tried to isolate the pertinent places, and all the former
10841 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
10842 someone should address this issue.

11250 * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to
11251 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
11252 One `#if YYDEBUG' remains, since it uses variables which are
11253 defined only if `YYDEBUG != 0'.

11972 (lex): Use literalchar.
11973 (lex): Implemented "..." tokens.
11974 (literalchar, lex, parse_percent_token): Made tokenbuffer
11975 always contain the token. This includes growing the token
11976 buffer while reading an integer.
11977 (parse_percent_token): Replaced if-else statement with percent_table.
11978 (parse_percent_token): Added % declarations as another
11979 way to specify the flags -n, -l, and -r. Also added hooks for
11980 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
11981 major changes to files.c.
11982 (lex) Retain in the incoming stream a character following
11983 an incorrect '/'.
