107 deterministic test suite.
108 Some consistency checks on symbols are performed after all the
109 symbols were read, by an iteration over the symbol table. This
110 traversal is nondeterministic, which can be a problem for test
111 cases.
112 Avoid this.
113 Addresses another form of nondeterminism reported by Joel E. Denny.

203 among the closing braces here. This fix might make the
204 generated code easier to debug, but otherwise it should be
205 insignificant because a trailing `:' is a C++ error already.

1329 They were used to get the symbol types, given a rule number, when
1330 displaying the top of the stack before a reduction. But the
1331 symbol type is available from the state stack. This has two be

1535 Another issue is to address idiosyncracies of C++: do not glue two
1536 closing angle brackets together (otherwise it's operator>>), and
1537 avoid sticking blindly a TYPE to the opening <, as it can result

1850 Finer input type for yytranslate.
1851 This patch is debatable: the tradition expects yylex to return an int
1852 which happens to correspond to token_number (which is an enum). This
1853 allows for instance to return characters (such as '*' etc.). But this
1854 goes against the stronger typing I am trying to have with the new
1855 lex interface which return a symbol_type. So in this case, feed
1856 yytranslate_ with a token_type.

b06df3c2
AD
2034 make_symbol provides a means to construct a full symbol (kind,
2035 value, location) in a single shot. It is meant to be a Symbol
2036 constructor, parameterized by the symbol kind so that overloading
2037 would prevent incorrect kind/value pairs. Unfortunately
2038 parameterized constructors do not work well in C++ (unless the
2039 parameter also appears as an argument, which is not acceptable),
2040 hence the use of a function instead of a constructor.

2255 Change the handling of the symbols in the skeletons.
2256 Before we were using tables which lines were the symbols and which
2257 columns were things like number, tag, type-name etc. It is was
2258 difficult to extend: each time a column was added, all the numbers had
2259 to be updated (you asked for colon $2, not for "tag"). Also, it was
2260 hard to filter these tables when only a subset of the symbols (say the
2261 tokens, or the nterms, or the tokens that have and external number
2262 *and* a type-name) was of interest.
de62edee 2263
d69c9694
AD
2264 Now instead of monolithic tables, we define one macro per cell. For
2265 instance "b4_symbol(0, tag)" is a macro name which contents is
2266 self-decriptive. The macro "b4_symbol" provides easier access to
2267 these cells.

2585 Add "%define assert" to variants.
2586 This is used to help the user catch cases where some value gets
2587 ovewritten by a new one. This should not happen, as this will
2588 probably leak.

2590 Unfortunately this uncovered a bug in the C++ parser itself: the
2591 lookahead value was not destroyed between two calls to yylex. For
2592 instance if the previous lookahead was a std::string, and then an int,
2593 then the value of the std::string was correctly taken (i.e., the
2594 lookahead was now an empty string), but std::string structure itself
2595 was not reclaimed.
de62edee 2596
2d32fc9f
AD
2597 This is now done in variant::build(other&) (which is used to take the
2598 value of the lookahead): other is not only stolen from its value, it
2599 is also destroyed. This incurs a new performance penalty of a few
2600 percent, and union becomes faster again.

2881 Fuse the three stacks into a single one.
de62edee 2882
b06df3c2
AD
2883 In order to make it easy to perform benchmarks to ensure that
2884 there are no performance loss, lalr1.cc is forked into
2885 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
2886 lalr1.cc.
2887
2888 Meanwhile, to make sure that lalr1-fusion.cc is correctly
2889 exercized by the test suite, the user must install a symbolic link
2890 from lalr1.cc to it.

2892 Instead of having three stacks (state, value, location), use a
2893 stack of triples. This considerably simplifies the code (and it
2894 will be easier not to require locations as currently does the C++
2895 parser), and also gives a 10% speedup according to
2896 etc/bench (probably mainly since memory allocation is done once
2897 instead of three times).

2899 Another motivation is to make it easier to destruct properly
2900 semantic values: now that they are bound to their state (hence
2901 symbol type) it will be easier to call the appropriate destructor.

2948 Use variants to support objects as semantic values.
b06df3c2
AD
2949 This patch was inspired by work by Michiel De Wilde. But he used
2950 Boost variants which (i) requires Boost on the user side, (ii) is
2951 slow, and (iii) has useless overhead (the parser knows the type of
2952 the semantic value there is no reason to duplicate this
2953 information as Boost.Variants do).
2954
2955 This implementation reserves a buffer large enough to store the
2956 largest objects. yy::variant implements this buffer. It was
2957 implemented with Quentin Hocquet.

4654 * src/lalr.c (state_lookahead_tokens_count): For code readability,
4655 move the check for disabled transitions to an aver since conflict
4656 resolution hasn't happened yet.
4657
4658 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
4659 labels a state as inconsistent just because it has error transitions.
4660 The original form of this check appeared in revision 1.1 of lalr.c,
4661 which was committed on 1991-12-21. Now (at least), changing the
4662 consistency label on such a state appears to have no useful effect in
4663 any of the places it is examined, which I enumerate below. The key
4664 point to understanding each item in this enumeration is that a state
4665 with an error transition is labelled consistent in the first place only
4666 if it has no rules, so the check cannot matter for states that have
4667 rules. (1) Labelling a state as inconsistent will cause set_conflicts
4668 to try to identify its conflicts, and a state must have *rules* to have
4669 conflicts. (2) Labelling a state as inconsistent will affect how
4670 action_row sets the default *rule* for the state. (3) Labelling a
4671 state as inconsistent will cause build_relations to add lookback edges
4672 to *rules* in that state.
4673 * src/state.h (struct state): Word the comment for member consistent
4674 more carefully.

5317 skeleton in other invocations. Also, move all %define value macros to

5684 mode, extend to check multiple yyparse invocations.
5685 (Exploding the Stack Size with Alloca): Extend to try with
5686 %push-pull-parser.

5689 * tests/calc.at (Simple LALR Calculator): Don't specify
5690 %skeleton "push.c" since %push-pull-parser implies that now.
5691 * tests/headers.at (export YYLTYPE): Don't check for the push
5692 declarations. Otherwise, this test case can't be used to see if push
5693 mode can truly emulate pull mode.

5699 push.c is renamed to yacc.c.

5703 For push mode, convert yyparse from a macro to a function, invoke yylex
5704 instead of passing a yylexp argument to yypull_parse, and don't
5705 generate yypull_parse or yyparse unless %push-pull-parser is declared.

5713 any time a pull parser is requested.
5714 Don't #define this as a wrapper around yypull_parse. Instead, when
5715 both push and pull are requested, make it a function that does that
5716 same thing.
5717 (yypull_parse): If there's a b4_prefix, #define this to
5718 b4_prefix[pull_parse] when both push and pull are requested.
5719 Don't define this as a function unless both push and pull are
5720 requested.
5721 Remove the yylexp argument and hard-code yylex invocation instead.
5722 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of

5752 (yypstate_new): Don't bother initializing the yyresult field since the
5753 initial value isn't used.
5754 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,

5781 Enable push parsers to operate in impure mode. Thus, %push-parser no
5782 longer implies %pure-parser. The point of this change is to move
5783 towards being able to test the push parser code by running the entire
5784 test suite as if %push-parser had been declared.
5785 * data/push.c (yypush_parse): For impure mode, remove the
5786 yypushed_char, yypushed_val, and yypushed_loc arguments.
5787 Instead, declare these as local variables initialized to the global
5788 yychar, yylval, and yylloc.
5789 For the first yypush_parse invocation only, restore the initial values
5790 of these global variables when it's time to read a token since they
5791 have been overwritten.
5792 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
5793 %push-parser.
5794 * tests/calc.at (Simple LALR(1) Calculator): Always declare
5795 %pure-parser along with %push-parser since this test case was designed

5836 Rearrange initialization of the parser state variables so that the

5839 initialized (with b4_location_initial_line and
5840 b4_location_initial_column) upon calling yypush_parse. However, that
5841 initialization now overwrites the first token's location;
5842 %initial-action assigning @$ already did the same thing, and both bugs
5843 will be fixed in a later patch.
5844 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.

6073 For pkgdatadir muscle, maintain previous functionality by using
6074 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
6075 is that b4_pkgdatadir is used inside m4_include in the skeletons, so

6944 Whether the default %destructor/%printer applies to a particular symbol
6945 isn't a question of whether the user *declares* that symbol (in %token,
6946 for example). It's a question of whether the user by any means
6947 *defines* the symbol at all (by simply using a char token, for
6948 example). $end is defined by Bison whereas any other token with token
6949 number 0 is defined by the user. The error token is always defined by
6950 Bison regardless of whether the user declares it with %token, but we
6951 may one day let the user define error as a nonterminal instead.
6952 * NEWS (2.3+): Say "user-defined" instead of "user-declared".

7470 warnings about types for $$, $n, @$, and @n can't be reported yet.
7471 (packgram): Translate the action and invoke grammar_rule_check now that
7472 all symbol declarations have been parsed.
7473 * src/scan-code.l (handle_action_dollar): Now that this is invoked
7474 after parsing the entire grammar file, the symbol list here in the case
7475 of a midrule is actually the midrule's empty RHS, so reference its
7476 parent rule's RHS where necessary.
7477 On the other hand, now that you can already know it's a midrule, you

7485 terminates a rule. symbol_list_print already does this correctly.
7486 * src/symlist.h (symbol_list.midrule_parent_rule,

7685 The Translation Project changed its way of publishing translations
7686 to maintainers. I haven't received any responses to my request
7687 for supporting the old way, or for documenting the new way. I

7987 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
7988 shell, not within 'make', so that 'make' by an ordinary builder
7989 (using GNU make) does not worry about configuring gzip. This also
7990 works around a bug reported independently by Keith Thompson and by
7991 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
7992 stderr rather than stdout, messing up the build logs.

7999 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
8000 not used.

8005 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
8006 state before an empty RHS is always resolved here. Only the location
8007 of that state is guaranteed to be resolved, and that's enough. This
8008 fixes the remaining bug reported by Derek M. Jones in
8009 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
8010 * tests/glr-regression.at (Uninitialized location when reporting
8011 ambiguity): Test the above case.
8012 Also, the embedded comments in this test case claim it checks the case
8013 of an empty RHS that has inherited the initial location. However, the
8014 corresponding LHS was already resolved, so yyresolveLocations didn't
8015 actually have reason to modify it. Fix this by forcing
8016 nondeterministic operation at the beginning of the parse.

8435 During deterministic GLR operation, user actions should be able to
8436 influence the parse by changing yychar. To make this easier to fix and

8465 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
8466 got from <http://bro-ids.org/download.html>. The bug is that
8467 when two actions appeared in succession, the second one was
8468 scanned before the first one was added to the grammar rule
8469 as a midrule action. Bison then output the incorrect warning
8470 "parse.y:905.17-906.36: warning: unused value: $3".

8759 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack):
8760 Allocate, deallocate, resize, and otherwise shuffle space for
8761 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
8762 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
8763 appropriately during nondeterministic operation.
8764 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
8765 members to store the current lookahead to be used by the deferred
8766 user action.
8767 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
8768 from which the RHS is taken. Set the lookahead members of the new
8769 yySemanticOption according to the lookahead status for stack yyk.
8770 (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to
8771 yyaddDeferredAction.
8772 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead
8773 members of yySemanticOption before invoking yyuserAction, and then set
8774 them back to their current values afterward.
8775 (yyparse): Set yychar = YYEMPTY where yytoken = YYEMPTY.
8776 (yyreportAmbiguity): Add /*ARGSUSED*/ to pacify lint.
8777 * tests/glr-regression.at: Remove `.' from the ends of recent test case
8778 titles for consistency.

8799 * data/glr.c (yyresolveValue): When merging semantic options, if at
8800 least one user action succeeds but a later one cuts the parse, then
8801 destroy the semantic value before returning rather than leaking it.
8802 (yyresolveStates): If a user action cuts the parse and thus
8803 yyresolveValue fails, ignore the (unset) semantic value rather than
8804 corrupting the yyGLRState, and empty the semantic options list since
8805 the user actions should have called all necessary destructors.
8806 Simplify code with YYCHK.

8808 cuts parse): New test case.

9154 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate):
9155 Prepend /*ARGSUSED*/, for lint's sake.
9156 * data/glr.c (YYUSE): Properly parenthesize, and use an alternate
9157 definition if 'lint' is defined.

9164 is C++ only.
9165 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
9166 * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
9167 Use YYID(0) rather than 0, for lint.
9168 (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.
9169 (yysyntax_error): Rewrite to avoid lint warnings about parenthesization.

9937 * tests/regression.at (Token definitions): Don't rely on
9938 AT_PARSER_CHECK for data that contains backslashes. It currently
9939 uses 'echo', and 'echo' isn't portable if its argument contains
9940 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
9941 that the byte '\0xff' is not printable in the C locale; it is,
9942 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
9943 not printable, so use '\0x81' to test.

10070 the new runtime-po domain, prime the pump by extracting the
10071 relevant strings from the obsolete translations. This code can be
10072 removed once the bison-runtime domain has been translated by each
10073 team.
10074
10075 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,

10102 the 2005-04-17 change, which is now accomplished (mostly) via
10103 changes in the parsers as described above.

10109 Fix more problems reported by twlevo@xs4all.nl.
10110 * tests/cxx-type.at: Don't pipe output of ./types through sed to
10111 remove trailing spaces. This loses the exit status of ./types,
10112 and isn't needed since ./types shouldn't be emitting trailing
10113 spaces.
10114 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
10115 as the stack isn't valid in that case.

10121 is used.

10129
10130 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
10131 to FILE * parameter, not to stderr. This fixes a typo introduced
10132 in the 2005-07-12 change.

10146 Destructor cleanups and regularization among the three skeletons.

10151 * data/glr.c (yyparse): Pop everything off the stack before
10152 freeing it, so that destructors get called properly.
10153 * data/lalr1.cc (yyreturn): Likewise.
10154 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.

10159 Some English-language cleanups for %destructor.

10172 Rename yyoverflowab to yyexhaustedlab.
10173 When memory exhaustion occurs during syntax-error reporting,
10174 report it separately rather than in a single diagnostic; this
10175 eases translation.

10186 can be understood only by someone who can read the
10187 (English-language) source code.

10189 Generate runtime-po/bison-runtime.pot automatically, so that we
10190 don't have to worry about garbage getting in that file. We'll
10191 make sure after the next official release that old msgids don't
10192 get lost. See

10195 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
10196 Now auto-generated.
10197 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
10198 Fix typos in explanations of the runtime file.
10199 * bootstrap: Change gettext keyword from YYI18N to YY_.
10200 Use standard Makefile.in.in in runtime-po, since we'll arrange
10201 for backward-compatible bison-runtime.po files in a different way.
10202 * data/glr.c (YY_): New macro, from yacc.c.
10203 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
10204 Translate messages intended for users.
10205 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
10206 the wording in the other skeletons. We don't know that the memory
10207 is virtual.
10208 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
10209 Use same method that yacc.c uses.
10210 Don't translate debugging messages.
10211 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
10212 it doesn't work (yet), and requires C++ expertise to fix.
10213 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
10214 Move defn to a more logical place, to be consistent with other
10215 skeletons.
10216 Don't translate debugging messages.
10217 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
10218 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
10219 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
10220 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.

10236 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
10237 (yyparse): New local variable yyresult to record the result.

10239 struct.

10241 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
10242 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
10243 if YYABORT is used).
10244 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
10245 yyparse status; put status > 1 into diagnostic.
10246 Check that status==2 works.

11016 Remove uses of 'short int' and 'unsigned short int'. This raises
11017 some arbitrary limits. It uses more memory but nowadays that's
11018 not much of an issue.
11019
11020 This change does not affect the generated parsers; that's a different
11021 task, as some users will want to conserve memory there.
11022
11023 Ideally we should use size_t to represent all object counts, and
11024 something like ptrdiff_t to represent signed differences of object
11025 counts; but that will require more code-cleanup than I have the

11424 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
11425 whether the reducion was empty or not. This leaves room to
11426 improve the use of YYLLOC_DEFAULT in such a case.
11427 lalr1.cc is still experimental, so changing this is acceptable.
11428 And finally, there are probably not many users who changed the
11429 handling of locations in GLR, so changing is admissible too.

11577 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
11578 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
11579 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
11580 the extra Bison directives instead of the whole series.
11581 Change the grammar so that there are recoverable errors, and
11582 unrecoverable errors. Now we can have the parser give up before
11583 consuming the whole input. As a result we now can observe that
11584 the lookahead is freed when needed.
11585 Change the parser source to parse argv[1] instead of a hard coded
11586 string.
11587 Simplify yylex, and give a value and location to EOF.
11588 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
11589 passed directives already coded in the file.
11590 Add some tests to check the location of "error".
11591 For some tests, the C++ parser is correct, and not yacc.c.
11592 For other tests, they provide different, but unsatisfying, values,
11593 so keep the C++ value so that at least one parser is "correct"
11594 according to the test suite.
11595 (Actions after errors): Remove, this is subsumed by the
11596 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

11774 Spent a few hours checking out which prerequisite versions the

11777 a seemingly endless set of combinations of versions more recent
11778 than that. The bottom line is that the current sources require
11779 fairly recent versions of the build tools, and it'll be some work
11780 to change this.

12296 When reducing initial empty rules, Bison parser read an initial
12297 location that is not defined. This results in garbage, and that
12298 affects Bison's own parser. Therefore we need (i) to extend Bison

26ec81e0

12595 The problem was that GLR parsers did not conform to the C standard,
12596 because actions like { $1 = $2 + $3; } expanded to expressions
12597 that invoked YYFILL in separate subexpressions, and YYFILL assigned
12598 to a local variable. The C standard says that expressions
12599 like (var = f ()) + (var = f ()) have undefined behavior.
12600 Another problem was that GCC sometimes issues warnings that
12601 yyfill and its parameters are unused.
12602
12603 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
12604 as possibly unused.
12605 (yyfill): New function.
12606 (YYFILL): Use it.
12607 (yyuserAction): Change type of yynormal to bool, so that it matches
12608 the new yyfill signature. Mark it as possibly unused.
12609

12611 Follow up on a bug I reported in February, where a Bison-generated
12612 parser can loop. Provide a test case and a fix for yacc.c. I
12613 don't have a fix for lalr1.cc or for glr.c, unfortunately.
12614 The original bug report is in:

12616
12617 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
12618 macro's size was becoming unwieldy.
12619 (yyerrlab): Do not discard an empty lookahead symbol, as this
12620 might destroy garbage.
12621 (yyerrorlab): New label, with the old contents of YYERROR,
12622 plus the following change: pop the stack of rhs corresponding
12623 to the production that invoked YYERROR. That is how Yacc
12624 behaves, and POSIX requires this behavior.
12625 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
12626 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
12627 Define 'alarm' to do nothing if unistd.h is not available.
12628 Add a new rule "exp: '-' error;" to test the above change to
12629 data/yacc.c. Use 'alarm' to abort any test taking longer than
12630 10 seconds, as it's probably looping.
12631 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
12632 Also, the new yacc.c generates two fewer diagnostics for an
12633 existing test.

12987 depend on *loc, so that the reader doesn't give the the false
12988 impression that *loc is initialized.
12989 (<INITIAL>"%%"): Do not bother setting code_start, since its value

12997 then it starts with the second %%'s beginning, instead of its end.

13261 we don't need to worry about yyerrlab1 being reported as an
13262 "unused label" by non-GCC C compilers. The downside is that if
13263 locations are used then a couple of statements are duplicated each
13264 time YYERROR is invoked, but the upside is that the warnings
13265 should vanish.
13266 (yyerrlab1): Move code to YERROR.

13283 popped). This means that the initial elements will not be freed
13284 explicitly, as is the case in yacc.c; it is not a problem, as
13285 these elements have fake values.

13394 * doc/bison.texinfo (Understanding): Use Yacc style for
13395 conflict reports. Also, use new way of locating rules.
13396 * src/conflicts.c (conflict_report):
13397 Renamed from conflict_report_yacc, removing the old
13398 'conflict_report'. Translate the entire conflict report at once,
13399 so that we don't assume that "," has the same interpretation in
13400 all languages.
13401 (conflicts_output): Use Yacc-style conflict report for each state,
13402 instead of our more-complicated style.
13403 (conflicts_print): Use Yacc-style conflict report, except print
13404 the input file name when not emulating Yacc.

13418 Fix a bug where error locations were not being recorded correctly.
13419 This problem was originally reported by Paul Hilfinger in

13422 * data/yacc.c (yyparse): New local var yylerrsp, to record the
13423 top of the location stack's error locations.
13424 (yyerrlab): Set it. When discarding a token, push its location
13425 onto yylerrsp so that we don't lose track of the error's end.
13426 (yyerrlab1): Now is only the target of YYERROR, so that we can
13427 properly record the location of the action that failed. For GCC
13428 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
13429 GCC warning about yyerrlab1 being unused if YYERROR is unused.
13430 (yyerrlab2): New label, which yyerrlab now falls through to.
13431 Compute the error's location by applying YYLLOC_DEFAULT to
13432 the locations of all the symbols that went into the error.
13433 * doc/bison.texinfo (Location Default Action): Mention that
13434 YYLLOC_DEFAULT is also invoked for syntax errors.
13435 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
13436 Error locations include the locations of all the tokens that were
13437 discarded, not just the last token.

13494 If the user does not define YYSTYPE as a macro, Bison now declares it
13495 using typedef instead of defining it as a macro. POSIX requires this.
13496 For consistency, YYLTYPE is also declared instead of defined.
13497
13498 %union directives can now have a tag before the `{', e.g., the
13499 directive `%union foo {...}' now generates the C code
13500 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
13501 The default union tag is `YYSTYPE', for compatibility with Solaris 9
13502 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
13503 instead of `yyltype'.
13504
13505 `yystype' and `yyltype' are now obsolescent macros instead of being
13506 typedefs or tags; they are no longer documented and will be
13507 withdrawn in a future release.

13513 (YYLTYPE): Renamed from yyltype.
13514 (yyltype, yystype): New (and obsolescent) macros,
13515 for backward compatibility.
13516 * data/yacc.c: Likewise.
13517
13518 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
13519 does not specify a union tag. This is for compatibility with
13520 Solaris 9 yacc.

13541 to return when scanning braced code.

13610
13611 Remove unportable casts and storage allocation tricks.
13612 While we're at it, remove almost all casts, since they
13613 usually aren't needed and are a sign of trouble.
13614
13615 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
13616
13617 * src/derives.c (derives_compute): Do not subtract NTOKENS from
13618 the pointer DSET returned by malloc; this isn't portable.
13619 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
13620 Similarly for DERIVES.
13621 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
13622 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
13623 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
13624
13625 * src/derives.c (derives_compute): Do not bother invoking
13626 int_of_rule_number, since rule numbers are integers.
13627
13628 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
13629 rather than XMALLOC (char, N).
13630
13631 * src/files.c (filename_split): Rewrite to avoid cast.
13632
13633 * src/gram.h (symbol_number_as_item_number,
13634 item_number_as_symbol_number, rule_number_as_item_number,
13635 item_number_as_rule_number):
13636 Now inline functions rather than macros, to avoid casts.
13637 * src/state.h (state_number_as_int): Likewise.
13638 * src/tables.c (state_number_to_vector_number,
13639 symbol_number_to_vector_number): Likewise.
13640
13641 * src/gram.h (int_of_rule_number): Remove; no longer used.
13642
13643 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
13644 since the resulting storage is always stored into.
13645
13646 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
13647 where it's needed.
13648
13649 * src/muscle_tab.c (muscle_m4_output):
13650 Now inline. Return bool, not int.
13651 * src/state.c (state_compare): Likewise.
13652 * src/symtab.c (symbol_check_defined,
13653 symbol_check_alias_consistency, symbol_pack, symbol_translation,
13654 hash_compare_symbol, hash_symbol):
13655 Likewise.
13656 * src/uniqstr.c (uniqstr_print): Likewise.
13657 * src/muscle_tab.c (muscle_m4_output_processor):
13658 New function, to avoid casts.
13659 * src/state.c (state_comparator, stage_hasher): Likewise.
13660 * src/symtab.c (symbol_check_defined_processor,
13661 symbol_check_alias_consistency_processor, symbol_pack_processor,
13662 symbol_translation_processor, hash_symbol_comparator,
13663 hash_symbol_hasher): Likewise.
13664 * src/uniqstr.c (uniqstr_print_processor): Likewise.
13665 * src/muscle_tab.c (muscles_m4_output):
13666 Use new functions instead of casting old functions unportably.
13667 * src/state.c (state_hash_new): Likewise.
13668 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
13669 symbols_token_translations_init):
13670 Likewise.
13671 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
13672
13673 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
13674 var instead of casting to long, to avoid casts.
13675 (prepare_states): Use MALLOC rather than alloca, so that we don't
13676 have to worry about alloca.
13677 * src/state.c (state_hash_lookup): Likewise.
13678
13679 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
13680 local var instead of casting to unsigned char, to avoid casts.
13681
13682 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
13683 STATE_ALLOC): Remove.
13684 (transitions_new, errs_new, reductions_new, state_new): Use malloc
13685 rather than calloc, and use offsetof to avoid allocating slightly
13686 too much storage.
13687 (state_new): Initialize all members.
13688
13689 * src/state.c (state_hash): Use unsigned accumulator, not signed.
13690
13691 * src/symtab.c (symbol_free): Remove; unused.
13692 (symbol_get): Remove cast in lhs of assignment.
13693 (symbols_do): Now static. Accept generic arguments, not
13694 hashing-related ones.
13695
13696 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
13697 (symbol_processor): Remove.
13698 (symbols_do): Remove decl; now static.

13702 (<inttypes.>, <stdint.h>): Include if available.
13703 (uintptr_t): New type, if system lacks it.
13704 (CALLOC, MALLOC, REALLOC): New macros.
13705 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
13706 new macros.
13707
13708 * src/tables.c (table_size): Now int, to pacify GCC.
13709 (table_grow, table_ninf_remap): Use signed table size.
13710 (save_row): Don't bother initializing locals when not needed.
13711 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
13712 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
13713
13714 * src/vcg.h: Correct misspellings.
13715
13716 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
13717
13718

13723 Change identifier spellings to avoid collisions with names
13724 that are reserved by POSIX.
13725
13726 Don't use names ending in _t, since POSIX reserves them.
13727 For consistency, remove _e and _s endings -- they're weren't
13728 needed to remove ambiguity. All uses changed.
13729 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
13730 turn was just renamed from struniq_t.

13942 instead of returning ID immediately, since we need to search for

14500 Use new @ escapes consistently. Represent brackets with @{ and @}
14501 rather than @<:@ and @:>@, since this works a bit better with dumb

14503 an escape. Use @oline@ and @ofile@ rather than __oline__ and
14504 __ofile__, to avoid unexpected expansions. Similarly, use @output
14505 rather than #output.
14506
14507 * data/c.m4 (b4_copyright): Omit file name from comment, since
14508 the file name could contain "*/".

14555 them with auto vars.

14844 indicates one.
14845 * src/output.c (output_skeleton): Use xfclose rather than fclose

14912 The last OS that we could find where this wouldn't work is
14913 SunOS 3.5, and that's too old to worry about now.
14914
14915 * data/glr.c (struct yyltype): Define members even when not

15289 Let nondeterministic skeletons be usable with deterministic
15290 tables.
15291
15292 With the patch, GAWK compiled by GCC without -O2 passes its test
15293 suite using a GLR parser driven by LALR tables. It fails with -O2
15294 because `struct stat' gives two different answers on my machine:
15295 88 (definition of an auto var) and later 96 (memset on this var).
15296 Hence the stack is badly corrumpted. The headers inclusion is to
15297 blame: if I move the awk.h inclusion before GLR's system header
15298 inclusion, the two struct stat have the same size.

15409 Portability fixes for bitsets; this also avoids several GCC
15410 warnings.
15411
15412 * lib/abitset.c: Include <stddef.h>, for offsetof.
15413 * lib/lbitset.c: Likewise.
15414
15415 * lib/abitset.c (abitset_bytes): Return a size that is aligned
15416 properly for vectors of objects. Do not assume that adding a
15417 header size to a multiple of a word size yields a value that is
15418 properly aligned for the whole union.
15419 * lib/bitsetv.c (bitsetv_alloc): Likewise.
15420
15421 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
15422 unique names for structures.
15423 * lib/ebitset.c (ebitset_bytes): Likewise.
15424 * lib/lbitset.c (lbitset_bytes): Likewise.
15425
15426 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
15427 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
15428 abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,
15429 abitset_andn_cmp, abitset_or, abitset_or_cmp, abitset_xor,
15430 abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
15431 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
15432 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
15433 to improve the type-checking that GCC can do.
15434 * lib/bitset.c (bitset_op4_cmp): Likewise.
15435 * lib/bitset_stats.c (bitset_stats_count,
15436 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,

15443 bitset_stats_andn_or_cmp, bitset_stats_or_and,
15444 bitset_stats_or_and_cmp): Likewise.

15446 lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
15447 lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
15448 lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
15449
15450 * lib/abitset.h: Include bitset.h, not bbitset.h.
15451 * lib/ebitset.h: Likewise.
15452 * lib/lbitset.h: Likewise.
15453
15454 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
15455 All instances of parameters of type enum bitset_opts are now of
15456 type enum_bitset_opts, to conform to the C Standard, and similarly
15457 for enum_bitset_type.
15458 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
15459 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
15460
15461 Do not use "struct bitset_struct" to mean different things in
15462 different modules. Not only is this confusing, it violates
15463 the C Standard, which requires that structure types in different
15464 modules must be compatible if one is to be passed to the other.
15465 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
15466 All instances of "struct bitset_struct *" replaced with "bitset".
15467 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
15468 (union bitset_union, struct abitset_struct, struct ebitset_struct,
15469 struct lbitset_struct, struct bitset_stats_struct): New types.
15470 All uses of struct bitset_struct changed to union bitset_union,
15471 etc.
ba0fe3c7 15472 * lib/abitset.c (struct abitset_struct, abitset,
f28a0f2d
PE
15473 struct bitset_struct): Remove.
15474 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
15475 struct bitset_struct): Remove.
15476 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
15477 bitset_struct): Remove.
15478 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
15479 Likewise.
15480
15481 Do not call a function of type T using a call that assumes the
15482 function is of a different type U. Standard C requires that a
15483 function must be called with a type that is compatible with its
15484 definition.
15485 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
15486 New decls.
15487 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
15488 New functions.
15489 * lib/ebitset.c (PFV): Remove.
15490 * lib/lbitset.c (PFV): Likewise.
15491 * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
15492 ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
15493 decls.
15494 (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
15495 (ebitset_vtable): Use them.
15496 * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
15497 lbitset_xor): New functions.
15498 (lbitset_vtable): Use them.
15499
15500 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
15501 Declare.
15502
15503 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
15504 GCC warning.
15505 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
15506 Use offsetof, for simplicity.

15511 the same width as int. This reapplies a hunk of the 2002-08-12 patch

15524 fixes.
15525 (Symbols): Mention that any negative value returned from yylex
15526 signifies end-of-input. Warn about negative chars. Mention
15527 the portable Standard C character set.
15528
15529 The GNU coding standard says CFLAGS and YFLAGS are reserved
15530 for the installer to set.
15531 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
15532 * src/Makefile.am (AM_CFLAGS): Likewise.
15533 (AM_YFLAGS): Renamed from YFLAGS.
15534
15535 Fix some MAX and MIN problems.
15536 * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.

15538 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
15539 * src/reader.c (reader): Use it.
15540
15541 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
15542 POSIX 1003.1-2001 has removed fgrep.
15543
155442002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
15545

19072 these states are automatically computed from the initial state.
19073 (generate_states): Adjust.
19074 * src/print.c: When reporting a rule number to the user, substract
19075 1, so that the axiom rule is rule 0, and the first user rule is 1.
19076 * src/reduce.c: Likewise.

19081 0: `$axiom: START-SYMBOL $'.

19083 number of the states has changed (the final state is no longer
19084 necessarily the last), catch up.

19111 Be sure to preserve the value of the eoftoken.
19112 (reader): Make sure eoftoken is defined.
19113 Initialize nsyms to 0: now eoftoken is created just like the others.
19114 * src/print.c (print_grammar): Don't special case the eof token.
19115 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
19116 lie anyway, albeit pleasant.
19117 * tests/calc.at: Exercise error messages with eoftoken.
19118 Change the grammar so that empty input is invalid.

19959 Because useless nonterminals are now kept alive (instead of being

20125 Do not limit the number of items in the stack to a value that fits
20126 in 'int', as this is an arbitrary limit on hosts with 64-bit
20127 size_t and 32-bit int.

22355 The location tracking mechanism is precious for parse error
22356 messages. Nevertheless, it is enabled only when `@n' is used in

22391 Test also `--verbose', `--defines' and `--name-prefix'. Testing
22392 the latter demonstrates a flaw in the handling of non debugging
22393 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
22394 was used in order to simplify:
22395
22396 #if YYDEBUG

22405 if (yydebug)
22406 {
22407 ...
22408 }

22462 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
22463 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
22464 difficult and introduced a lot of core dump. It turns out that
22465 Bison used an implementation of `xmalloc' based on `calloc', and
22466 at various places it does depend upon the initialization to 0. I
22467 have not tried to isolate the pertinent places, and all the former
22468 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
22469 someone should address this issue.

22880 defined only if `YYDEBUG != 0'.

23599 (lex): Use literalchar.
23600 (lex): Implemented "..." tokens.
23601 (literalchar, lex, parse_percent_token): Made tokenbuffer
23602 always contain the token. This includes growing the token
23603 buffer while reading an integer.
23604 (parse_percent_token): Replaced if-else statement with percent_table.
23605 (parse_percent_token): Added % declarations as another
23606 way to specify the flags -n, -l, and -r. Also added hooks for
23607 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
23608 major changes to files.c.
23609 (lex) Retain in the incoming stream a character following
23610 an incorrect '/'.
23611 (skip_white_space, lex): Revised most error messages
