JD
12 * src/reader.c (get_merge_function): Don't set the merger type yet.
13 (record_merge_function_type): New function for setting the merger type
14 and checking for clashes.
15 (grammar_current_rule_merge_set): Set the location of the %merge for
16 the current rule.
17 (packgram): Invoke record_merge_function_type for each rule now that
18 all symbol type declarations have been parsed.
19 * src/reader.h (merger_list.type_declaration_location): New member
20 storing the location of the first %merge from which the type for this
21 merging function was derived.
22 * src/symlist.h (symbol_list.merger_declaration_location): New member
23 storing the location of a rule's %merge, if any.
24 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
25 declared later): New test to catch the error fixed by the above patch.

34 Don't mistake the type of $$ in a midrule to be that of its parent
35 rule's $$.
ffa4ba3a
JD
36 * src/reader.c (grammar_current_rule_end): Don't invoke
37 grammar_rule_check yet since not all symbol declarations may have been
38 parsed yet.
39 (grammar_midrule_action): Likewise.
40 Don't record whether the midrule's $$ has been used yet since actions
41 haven't been translated yet.
42 Record the midrule's parent rule and its RHS index within the parent
43 rule.
44 (grammar_current_rule_action_append): Don't translate the action yet
45 since not all symbol declarations may have been parsed yet and, thus,
46 warnings about types for $$, $n, @$, and @n can't be reported yet.
47 (packgram): Translate the action and invoke grammar_rule_check now that
48 all symbol declarations have been parsed.
49 * src/scan-code.l (handle_action_dollar): Now that this is invoked
50 after parsing the entire grammar file, the symbol list here in the case
51 of a midrule is actually the midrule's empty RHS, so reference its
52 parent rule's RHS where necessary.
53 On the other hand, now that you can already know it's a midrule, you
54 aren't forced to think $$ has the same type as its parent rule's $$.
55 (handle_action_at): In the case of a midrule, reference the parent rule
56 where necessary.
57 * src/symlist.c (symbol_list_new): Initialize new midrule-related
58 members.
59 (symbol_list_length): Now that this is invoked after all rules have
60 been parsed, a NULL symbol (rather than a NULL symbol list node)
61 terminates a rule. symbol_list_print already does this correctly.
62 * src/symlist.h (symbol_list.midrule_parent_rule,
63 symbol_list.midrule_parent_rhs_index): New members so that midrules can
64 remember their relationships with their parents.
65 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
66 fixed by the above patch.
67 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
68 implementing...
69 (Unused values): ... this old test case and...
70 (Unused values before symbol declarations): ... this new test case.
71 This one is the same as `Unused values' except that all symbol
72 declarations appear after the rules in order to catch the rest of the
73 errors fixed by the above patch.

99 to be a rule action. Mentioned at
100 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
101 * src/scan-gram.l: Move midrule action detection from the start of the
102 scanning of any braced code to...
103 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
104 action. For readability, use $2 and @2 rather than the equivalent
105 global variables.
106 * tests/regression.at (Braced code in declaration in rules section):
107 New test to catch the error fixed by the above patch.
108
109 Work on code readability some.
110 * src/scan-code.l (current_rule): Get rid of this misleading and
111 redundant declaration: it's actually extern'ed in reader.h.
112 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
113 translate_action): Add a rule argument and use it instead of the global
114 current_rule.
115 (translate_rule_action): This already receives current_rule through an
116 argument, so pass it on to translate_action instead of assigning
117 current_rule to current_rule.
118 (translate_symbol_action, translate_code): Pass rule = NULL to
119 translate_action.

125 blocks from post-prologue blocks. Add new order-independent
126 declarations %before-header and %after-header as alternatives to the
127 traditional Yacc pre-prologue and post-prologue blocks. Discussed at

262 The Translation Project changed its way of publishing translations
263 to maintainers. I haven't received any responses to my request
264 for supporting the old way, or for documenting the new way. I
265 have modified 'bootstrap' to use screen scraping
266 (in this case, HTML scraping). This is unreliable and inelegant,
267 but I don't see any better way. Yuck.
268 * bootstrap (TP_URL, WGET_COMMAND): New vars.
269 (get_translations): New function, which uses HTML scraping to
270 deduce locations of latest translations.
271 Use this function to grab both bison and bison-runtime .po files.
272 Don't bother priming the pump for the runtime-po domain any more,
273 as it's now translated better than bison is.

443 Extract the parsing of user actions from the grammar scanner.
444 As a consequence, the relation between the grammar scanner and

566 (using GNU make) does not worry about configuring gzip. This also
567 works around a bug reported independently by Keith Thompson and by

588 ambiguity): Test the above case.
589 Also, the embedded comments in this test case claim it checks the case
590 of an empty RHS that has inherited the initial location. However, the
591 corresponding LHS was already resolved, so yyresolveLocations didn't
592 actually have reason to modify it. Fix this by forcing
593 nondeterministic operation at the beginning of the parse.

1613 * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.
1614 (yylval, yylloc): If pure, #define to yystackp->yyval and
1615 yystackp->yyloc similar to yychar and yynerrs.
1616 (yyparse): If pure, remove local yylval and yylloc. Add local
1617 yystackp to accommodate pure definitions of yylval and yylloc.
1618 (b4_lex_param, b4_lyyerror_args, b4_lpure_args): If pure, change
1619 yylvalp and yyllocp to &yylval and &yylloc.
1620 (nerrs, char, lval, lloc): If pure, add #define's for b4_prefix[]
1621 namespace. Previously, nerrs and char were missing, but lval and lloc
1622 weren't necessary.
1623 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Remove
1624 yylvalp and yyllocp parameters since, if pure, these are now always
1625 accessible through yystackp. If not pure, they are still accessible

2066 Use unlocked I/O for a minor performance improvement on hosts like
2067 GNU/Linux and Solaris that support unlocked I/O. The basic idea

2518 that the byte '\0xff' is not printable in the C locale; it is,
2519 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are

2577 it's error-prone and "make maintainer-distcheck" rejects it.

2679 the 2005-04-17 change, which is now accomplished (mostly) via
2680 changes in the parsers as described above.

2686 Fix more problems reported by twlevo@xs4all.nl.
2687 * tests/cxx-type.at: Don't pipe output of ./types through sed to
2688 remove trailing spaces. This loses the exit status of ./types,
2689 and isn't needed since ./types shouldn't be emitting trailing
2690 spaces.
2691 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,

2775 Fix typos in explanations of the runtime file.
2776 * bootstrap: Change gettext keyword from YYI18N to YY_.
2777 Use standard Makefile.in.in in runtime-po, since we'll arrange
2778 for backward-compatible bison-runtime.po files in a different way.
2779 * data/glr.c (YY_): New macro, from yacc.c.
2780 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
2781 Translate messages intended for users.

2783 the wording in the other skeletons. We don't know that the memory
2784 is virtual.

3542 Private, not public.
3543 (parser::parse): Return ints, not bool.
3544 Returning a bool introduces a problem: 0 corresponds to false, and
3545 it seems weird to return false on success. Returning true changes
3546 the conventions for yyparse.
3547 Alternatively we could return void and send an exception.
3548 There is no clear consensus (yet?).

3593 Remove uses of 'short int' and 'unsigned short int'. This raises
3594 some arbitrary limits. It uses more memory but nowadays that's
3595 not much of an issue.
3596
3597 This change does not affect the generated parsers; that's a different
3598 task, as some users will want to conserve memory there.
3599
3600 Ideally we should use size_t to represent all object counts, and

4001 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
4002 whether the reducion was empty or not. This leaves room to
4003 improve the use of YYLLOC_DEFAULT in such a case.
4004 lalr1.cc is still experimental, so changing this is acceptable.
4005 And finally, there are probably not many users who changed the
4006 handling of locations in GLR, so changing is admissible too.

4154 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
4155 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
4156 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
4157 the extra Bison directives instead of the whole series.
4158 Change the grammar so that there are recoverable errors, and
4159 unrecoverable errors. Now we can have the parser give up before
4160 consuming the whole input. As a result we now can observe that
4161 the lookahead is freed when needed.
4162 Change the parser source to parse argv[1] instead of a hard coded
4163 string.
4164 Simplify yylex, and give a value and location to EOF.
4165 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
4166 passed directives already coded in the file.
4167 Add some tests to check the location of "error".
4168 For some tests, the C++ parser is correct, and not yacc.c.
4169 For other tests, they provide different, but unsatisfying, values,
4170 so keep the C++ value so that at least one parser is "correct"
4171 according to the test suite.

4173 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

4351 Spent a few hours checking out which prerequisite versions the
4352 current sources actually require. I went all the way back to
4353 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
4354 a seemingly endless set of combinations of versions more recent
4355 than that. The bottom line is that the current sources require
4356 fairly recent versions of the build tools, and it'll be some work
4357 to change this.
4358 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
4359 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
4360 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.

4362 currently needed.

4873 When reducing initial empty rules, Bison parser read an initial
4874 location that is not defined. This results in garbage, and that

5170 Fix a GLR parser bug I reported in February; see

26ec81e0

5172 The problem was that GLR parsers did not conform to the C standard,
5173 because actions like { $1 = $2 + $3; } expanded to expressions
5174 that invoked YYFILL in separate subexpressions, and YYFILL assigned
5175 to a local variable. The C standard says that expressions
5176 like (var = f ()) + (var = f ()) have undefined behavior.
5177 Another problem was that GCC sometimes issues warnings that
5178 yyfill and its parameters are unused.
5179
5180 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
5181 as possibly unused.
5182 (yyfill): New function.
5183 (YYFILL): Use it.
5184 (yyuserAction): Change type of yynormal to bool, so that it matches
5185 the new yyfill signature. Mark it as possibly unused.

5188 Follow up on a bug I reported in February, where a Bison-generated
5189 parser can loop. Provide a test case and a fix for yacc.c. I
5190 don't have a fix for lalr1.cc or for glr.c, unfortunately.
5191 The original bug report is in:

5193
5194 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
5195 macro's size was becoming unwieldy.
5196 (yyerrlab): Do not discard an empty lookahead symbol, as this
5197 might destroy garbage.
5198 (yyerrorlab): New label, with the old contents of YYERROR,
5199 plus the following change: pop the stack of rhs corresponding
5200 to the production that invoked YYERROR. That is how Yacc
5201 behaves, and POSIX requires this behavior.
5202 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
5203 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
5204 Define 'alarm' to do nothing if unistd.h is not available.
5205 Add a new rule "exp: '-' error;" to test the above change to
5206 data/yacc.c. Use 'alarm' to abort any test taking longer than
5207 10 seconds, as it's probably looping.
5208 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
5209 Also, the new yacc.c generates two fewer diagnostics for an
5210 existing test.

5837 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
5838 we don't need to worry about yyerrlab1 being reported as an
5839 "unused label" by non-GCC C compilers. The downside is that if
5840 locations are used then a couple of statements are duplicated each
5841 time YYERROR is invoked, but the upside is that the warnings
5842 should vanish.
5843 (yyerrlab1): Move code to YERROR.

5860 popped). This means that the initial elements will not be freed
5861 explicitly, as is the case in yacc.c; it is not a problem, as
5862 these elements have fake values.

5970 of the 2002-07-30 change.
5971 * doc/bison.texinfo (Understanding): Use Yacc style for
5972 conflict reports. Also, use new way of locating rules.
5973 * src/conflicts.c (conflict_report):
5974 Renamed from conflict_report_yacc, removing the old
5975 'conflict_report'. Translate the entire conflict report at once,
5976 so that we don't assume that "," has the same interpretation in
5977 all languages.
5978 (conflicts_output): Use Yacc-style conflict report for each state,
5979 instead of our more-complicated style.
5980 (conflicts_print): Use Yacc-style conflict report, except print
5981 the input file name when not emulating Yacc.
5982 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
5983 Conflicted Reduction, %expect not enough, %expect too much,

5999 * data/yacc.c (yyparse): New local var yylerrsp, to record the
6000 top of the location stack's error locations.
6001 (yyerrlab): Set it. When discarding a token, push its location
6002 onto yylerrsp so that we don't lose track of the error's end.
6003 (yyerrlab1): Now is only the target of YYERROR, so that we can
6004 properly record the location of the action that failed. For GCC
6005 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
6006 GCC warning about yyerrlab1 being unused if YYERROR is unused.
6007 (yyerrlab2): New label, which yyerrlab now falls through to.
6008 Compute the error's location by applying YYLLOC_DEFAULT to
6009 the locations of all the symbols that went into the error.
6010 * doc/bison.texinfo (Location Default Action): Mention that
6011 YYLLOC_DEFAULT is also invoked for syntax errors.
6012 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

6071 If the user does not define YYSTYPE as a macro, Bison now declares it
6072 using typedef instead of defining it as a macro. POSIX requires this.
6073 For consistency, YYLTYPE is also declared instead of defined.
6074
6075 %union directives can now have a tag before the `{', e.g., the
6076 directive `%union foo {...}' now generates the C code
6077 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
6078 The default union tag is `YYSTYPE', for compatibility with Solaris 9
6079 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
6080 instead of `yyltype'.
6081
6082 `yystype' and `yyltype' are now obsolescent macros instead of being
6083 typedefs or tags; they are no longer documented and will be

6093 * data/yacc.c: Likewise.
6094

6096 does not specify a union tag. This is for compatibility with
6097 Solaris 9 yacc.

6116 has (or usually has) an immediately-following braced code.

6118 to return when scanning braced code.

6448 then the . include files in double-quotes (alphabetized). Fix
6449 dependency breakages encountered in this process, as follows:

7077 Use new @ escapes consistently. Represent brackets with @{ and @}
7078 rather than @<:@ and @:>@, since this works a bit better with dumb
7079 editors like vi. Represent @ with @@, since @ is now consistently
7080 an escape. Use @oline@ and @ofile@ rather than __oline__ and
7081 __ofile__, to avoid unexpected expansions. Similarly, use @output
7082 rather than #output.
7083
7084 * data/c.m4 (b4_copyright): Omit file name from comment, since
7085 the file name could contain "*/".
7086 (b4_synclines_flag): Don't quote the 2nd argument; it should already
7087 be quoted. All uses changed.

7101 mishandled funny characters in file names, and anyway it isn't
7102 needed any more.

7128 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
7129 Use new escapes @{ and @} for [ and ].
7130
7131 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
7132 them with auto vars.
7133 Switch to new escape scheme, where @ is the escape character uniformly.
7134 Abort if a stray escape character is found. Avoid unbounded input
7135 buffer when parsing non-escaped text.

7146 table.
7147 (yygetLRActions, yyrecoverParseError): Use them.

7149 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
7150 counted in the token inserted at end of file. Now takes
7151 location_t *, not location_t, so that the location can be
7152 adjusted. All uses changed.

7489 The last OS that we could find where this wouldn't work is
7490 SunOS 3.5, and that's too old to worry about now.
7491

7555 for a freestanding C89 compiler.

7866 Let nondeterministic skeletons be usable with deterministic
7867 tables.
7868
7869 With the patch, GAWK compiled by GCC without -O2 passes its test
7870 suite using a GLR parser driven by LALR tables. It fails with -O2
7871 because `struct stat' gives two different answers on my machine:
7872 88 (definition of an auto var) and later 96 (memset on this var).
7873 Hence the stack is badly corrumpted. The headers inclusion is to
7874 blame: if I move the awk.h inclusion before GLR's system header
7875 inclusion, the two struct stat have the same size.

7929 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,

8447 to minimize the number of warnings from xgettext.
8448 (handle_action_dollar, handle_action_at): Don't use isdigit,
8449 as it mishandles negative chars and it may not work as expected
8450 outside the C locale.

8453 this is a GCC extension and is not portable to other compilers.

8456 Do not include <ctype.h>; no longer needed.

8461 it's not portable.

11317 * src/system.h: We don't need nor want bcopy.
11318 Throw away MS-DOS crap: we don't need getpid.
11319 * configure.in: We don't need strndup. It was even causing
11320 problems: because Flex includes the headers *before* us,
11321 _GNU_SOURCE is not defined by config.h, and therefore strndup was
11322 not visible.
11323 * lib/xstrndup.c: New.
11324 * src/scan-skel.l: Use it.
11325 Be sure to initialize yylval.muscle member when scanning a MUSCLE.

11339 Include skeleton.h.
11340 Don't use %option yylineno: it seems that then Flex imagines
11341 REJECT has been used, and therefore it won't reallocate its
11342 buffers (which makes no other sense to me than a bug). It results
11343 in warnings for `unused: yy_flex_realloc'.

11650 (generate_states): Adjust.
11651 * src/print.c: When reporting a rule number to the user, substract

11688 Be sure to preserve the value of the eoftoken.
11689 (reader): Make sure eoftoken is defined.
11690 Initialize nsyms to 0: now eoftoken is created just like the others.
11691 * src/print.c (print_grammar): Don't special case the eof token.
11692 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
11693 lie anyway, albeit pleasant.

12536 Because useless nonterminals are now kept alive (instead of being
12537 `destroyed'), we now sometimes examine them, and store information
12538 related to them. Hence we need to know their number, and adjust
12539 memory allocations.

12541 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
12542 static.
12543 * src/LR0.c (allocate_itemsets): The memory allocated to
12544 `symbol_count' was used for two different purpose: once to count
12545 the number of occurrences of each symbol, and later reassigned to
12546 `shift_symbol', containing the symbol that can be shifted from a
12547 given state.
12548 Deobfuscate, i.e., allocate, use and free `symbol_count' here
12549 only, and...
12550 (new_itemsets): Allocate `shift_symbol' here.
12551 (allocate_itemsets): symbol_count includes useless nonterminals.
12552 Make room for them.
12553 (free_storage): Use `free', not `XFREE', for pointers that cannot
12554 be null.

12696
12697 (yyparse): Don't dump core if alloca or malloc fails; instead, report
12698 a parser stack overflow. Allocate just one block of memory for all
12699 three stacks, instead of allocating three blocks; this typically is
12700 faster and reduces fragmentation.

14932 The location tracking mechanism is precious for parse error
14933 messages. Nevertheless, it is enabled only when `@n' is used in
14934 the grammar, which is a different issue (you can use it in error
14935 message, but not in the grammar per se). Therefore, there should
14936 be another means to enable it.

14968 Test also `--verbose', `--defines' and `--name-prefix'. Testing
14969 the latter demonstrates a flaw in the handling of non debugging
14970 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
14971 was used in order to simplify:
14972
14973 #if YYDEBUG
14974 if (yydebug)
14975 {
14976 ...
14977 }
14978 #endif

14980 into
14981
14982 if (yydebug)
14983 {
14984 ...
14985 }
14986
14987 unfortunately this leads to a CPP conflict when
14988 `--name-prefix=foo' is used since it produces `#define yydebug
14989 foodebug'.

15039 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
15040 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
15041 difficult and introduced a lot of core dump. It turns out that
15042 Bison used an implementation of `xmalloc' based on `calloc', and
15043 at various places it does depend upon the initialization to 0. I
15044 have not tried to isolate the pertinent places, and all the former
15045 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
15046 someone should address this issue.

15417 There is now a pseudo variable @$ (readble and writable), location
15418 of the lhs of the rule (by default ranging from the location of
