3 Introduce make_symbol.
4 make_symbol provides a means to construct a full symbol (kind, value,
5 location) in a single shot. It is meant to be a Symbol constructor,
6 parameterized by the symbol kind so that overloading would prevent
7 incorrect kind/value pairs. Unfortunately parameterized constructors do
8 not work well in C++ (unless the parameter also appears as an argument,
9 which is not acceptable), hence the use of a function instead of a
10 constructor.
11
12 * data/lalr1.cc (b4_symbol_constructor_declaration_)
13 (b4_symbol_constructor_declarations)
14 (b4_symbol_constructor_specialization_)
15 (b4_symbol_constructor_specializations)
16 (b4_symbol_constructor_definition_)
17 (b4_symbol_constructor_definitions): New.
18 Use them where appropriate to generate declaration, declaration of
19 the specializations, and implementations of the templated
20 overloaded function "make_symbol".
21 (variant::variant): Always define a default ctor.
22 Also provide a copy ctor.
23 (symbol_base_type, symbol_type): New ctor overloads for value-less
24 symbols.
25 (symbol_type): Now public, so that functions such as yylex can use
26 it.

31 * src/output.c (is_identifier): New.
32 (symbol_definitions_output): Use it to define tag_is_id.
33 But maybe this should be done at m4 level?

37 Test 214 was failing: it greps with a pattern containing [ ]*
38 which obviously meant to catch spaces and tabs, but contained only
39 spaces. Tabulations in sources are a nuisance, so to simplify the
40 matter, get rid of all the tabulations in the Java sources. The
41 other skeletons will be treated equally later.
42
43 * data/java.m4, data/lalr1.java: Untabify.
44 * tests/java.at: Simplify AT_CHECK_JAVA_GREP invocations:
45 tabulations are no longer generated.

225 Change the handling of the symbols in the skeletons.
226 Before we were using tables which lines were the symbols and which
227 columns were things like number, tag, type-name etc. It is was
228 difficult to extend: each time a column was added, all the numbers had
229 to be updated (you asked for colon $2, not for "tag"). Also, it was
230 hard to filter these tables when only a subset of the symbols (say the
231 tokens, or the nterms, or the tokens that have and external number
232 *and* a type-name) was of interest.
de62edee 233
d69c9694
AD
234 Now instead of monolithic tables, we define one macro per cell. For
235 instance "b4_symbol(0, tag)" is a macro name which contents is
236 self-decriptive. The macro "b4_symbol" provides easier access to
237 these cells.

286 Unfortunately it is not possible to reuse the %prec directive. This
287 is because to please POSIX, we do not require to end the rules with a

de62edee 289
d78f0ac9 290 foo: bar %prec baz
de62edee 291

554 Add "%define assert" to variants.

559 Unfortunately this uncovered a bug in the C++ parser itself: the
560 lookahead value was not destroyed between two calls to yylex. For
561 instance if the previous lookahead was a std::string, and then an int,
562 then the value of the std::string was correctly taken (i.e., the
563 lookahead was now an empty string), but std::string structure itself
564 was not reclaimed.
de62edee 565
2d32fc9f
AD
566 This is now done in variant::build(other&) (which is used to take the
567 value of the lookahead): other is not only stolen from its value, it
568 is also destroyed. This incurs a new performance penalty of a few
569 percent, and union becomes faster again.

850 Fuse the three stacks into a single one.
851 In order to make it easy to perform benchmarks to ensure that there are no
852 performance loss, lalr1.cc is forked into lalr1-fusion.cc. Eventually,
853 lalr1-fusion.cc will replace lalr1.cc.
de62edee 854
0e0ed236
AD
855 Meanwhile, to make sure that lalr1-fusion.cc is correctly exercized by the
856 test suite, the user must install a symbolic link from lalr1.cc to it.

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

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

913 Use variants to support objects as semantic values.
914 This patch was inspired by work by Michiel De Wilde. But he used Boost
915 variants which (i) requires Boost on the user side, (ii) is slow, and
916 (iii) has useless overhead (the parser knows the type of the semantic value
917 there is no reason to duplicate this information as Boost.Variants do).

919 This implementation reserves a buffer large enough to store the largest
920 objects. yy::variant implements this buffer. It was implemented with

2109 Make xml2dot.xsl and --graph produce the same output.
2110 * data/xslt/xml2dot.xsl (xsl:template match="rule"): Use a `&#10;'
2111 instead of a `\n'. That is, don't add escapes yet or they'll be doubly
2112 escaped later.
2113 (xsl:template name="output-node"): Use the new escape template instead
2114 of the string-replace template directly.
2115 (xsl:template name="output-edge"): Likewise.
2116 (xsl:template name="escape"): New, escapes backslashes and newlines in
2117 addition to quotation marks.

2119 whitespace to output for legibility.
2120
2121 Make xml2text.xsl and --report produce the same output, and remove the
2122 XML "conflicts" element since a conflict summary is easily extracted
2123 from the automaton.

2126 * data/xslt/xml2text.xsl: Import bison.xsl.
2127 (xsl:template match="bison-xml-report"): Instead of styling the
2128 "conflicts" element, style the "automaton" element with mode
2129 "conflicts". Unlike the former, the latter lists S/R and R/R
2130 conflicts for a state on the same line.
2131 (xsl:template match="conflicts"): Remove.
2132 (xsl:template match="conflict"): Remove.
2133 (xsl:template match="terminal"): Line-wrap the list of rules in which
2134 the terminal is used.

2157 Improve C++ namespace support. Discussed starting at
2158 <http://lists.gnu.org/archive/html/help-bison/2007-09/msg00016.html>.
2159 * data/c++.m4: (b4_namespace_ref, b4_namespace_open,
2160 b4_namespace_close): New macros that interpret the %define variable
2161 "namespace" so its value can contain "::" to indicate nested

2164 the above macros.
2165 * data/lalr1.cc (b4_namespace): Likewise.
2166 * data/location.cc (b4_namespace): Likewise.
2167 * doc/bison.texinfo (Decl Summary): Move `%define push_pull' entry
2168 inside a new table in the general %define entry. Document `%define
2169 namespace' there as well. Point the %name-prefix entry to it since it
2170 explains it more completely in the case of C++.
2171 (C++ Bison Interface): Mention `%define namespace' instead of
2172 %name-prefix.
2173 (Table of Symbols): Remove the `%define push_pull' entry. The %define
2174 entry suffices.
2175 * tests/c++.at (Relative namespace references): New test case.

2214 * data/bison.m4 (b4_cat): New.
2215 (b4_error, b4_error_at): Use b4_cat to send error directives directly
2216 to stdout so they don't become arguments to other macros. Update
2217 comments and add examples.
2218 (b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and
2219 add examples.
2220 (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately
2221 after printing the error directive so that M4 doesn't report subsequent
2222 problems that are induced by this problem.
2223 * src/scan-skel.l: Recognize @` digraph outside of directive arguments

2618 * src/lalr.c (state_lookahead_tokens_count): For code readability,
2619 move the check for disabled transitions to an aver since conflict
2620 resolution hasn't happened yet.
2621
2622 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
2623 labels a state as inconsistent just because it has error transitions.
2624 The original form of this check appeared in revision 1.1 of lalr.c,
2625 which was committed on 1991-12-21. Now (at least), changing the
2626 consistency label on such a state appears to have no useful effect in
2627 any of the places it is examined, which I enumerate below. The key
2628 point to understanding each item in this enumeration is that a state
2629 with an error transition is labelled consistent in the first place only
2630 if it has no rules, so the check cannot matter for states that have
2631 rules. (1) Labelling a state as inconsistent will cause set_conflicts
2632 to try to identify its conflicts, and a state must have *rules* to have
2633 conflicts. (2) Labelling a state as inconsistent will affect how
2634 action_row sets the default *rule* for the state. (3) Labelling a
2635 state as inconsistent will cause build_relations to add lookback edges
2636 to *rules* in that state.
2637 * src/state.h (struct state): Word the comment for member consistent
2638 more carefully.

3276 Instead of having skeletons declare all valid %define variables and
3277 %code qualifiers, provide macros that retrieve the associated values
3278 and build these lists automatically. Thus Bison will now warn when a
3279 variable or qualifier is not used by the skeleton in the current
3280 invocation regardless of whether it might sometimes be used by that
3281 skeleton in other invocations. Also, move all %define value macros to
3282 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
3283 form, which is replaced by %code.
3284 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
3285 (b4_check_user_names): ... this, and change the series of valid name
3286 arguments to a single list argument for names used in the skeleton
3287 similar to the existing list argument for names used in the grammar.
3288 Warn instead of complaining.
3289 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
3290 values and %code code, to format %code code properly, and to build
3291 lists of all %define variables and %code qualifiers used in the
3292 skeleton: b4_skeleton_percent_define_variables and
3293 b4_skeleton_percent_code_qualifiers.

3297 the skeleton names lists can finish building first. In place of
3298 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
3299 expect the lists b4_user_percent_define_variables and
3300 b4_user_percent_code_qualifiers.

3646 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to

3745 Enable push parsers to operate in impure mode. Thus, %push-parser no
3746 longer implies %pure-parser. The point of this change is to move
3747 towards being able to test the push parser code by running the entire
3748 test suite as if %push-parser had been declared.
3749 * data/push.c (yypush_parse): For impure mode, remove the
3750 yypushed_char, yypushed_val, and yypushed_loc arguments.
3751 Instead, declare these as local variables initialized to the global
3752 yychar, yylval, and yylloc.
3753 For the first yypush_parse invocation only, restore the initial values
3754 of these global variables when it's time to read a token since they
3755 have been overwritten.
3756 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
3757 %push-parser.
3758 * tests/calc.at (Simple LALR(1) Calculator): Always declare
3759 %pure-parser along with %push-parser since this test case was designed

3800 Rearrange initialization of the parser state variables so that the

3802 mode. This patch also fixes at least a bug such that yylloc was not
3803 initialized (with b4_location_initial_line and
3804 b4_location_initial_column) upon calling yypush_parse. However, that
3805 initialization now overwrites the first token's location;
3806 %initial-action assigning @$ already did the same thing, and both bugs
3807 will be fixed in a later patch.

3818 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
3819 yypush_parse, only do it for the first invocation.

3837 For push mode, remove yypush_parse's local equivalents of these
3838 variables to eliminate unnecessary copying between the two sets at
3839 run-time. This patch also fixes at least a bug related to multiple

3854 parser state variable declarations with

4011 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
4012 `bison ', use m4_index instead of m4_substr since chopping up a string
4013 containing M4-special characters causes problems here.
4014
4015 Fix a couple of bugs related to special characters in user-specified
4016 file names, and make it easier for skeletons to compute output file
4017 names with the same file name prefix as Bison-computed output file
4018 names.
4019 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
4020 b4_parser_file_name and b4_spec_defines_file instead of
4021 @output_parser_name@ and @output_header_name@, which are now redundant.
4022 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
4023 b4_parser_file_name, b4_spec_defines_file, and the new
4024 @basename(FILENAME@) instead of @output_parser_name@ and
4025 @output_header_name@, which inappropriately escaped the file names as
4026 C string literals.
4027 * src/files.c (all_but_ext): Remove static qualifier.
4028 (compute_output_file_names): Move `free (all_but_ext)' to...
4029 (output_file_names_free): ... here since all_but_ext is needed later.
4030 * src/files.h (all_but_ext): Extern.
4031 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
4032 exactly what MUSCLE_INSERT_STRING used to do.
4033 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
4034 characters are escaped properly.
4035 * src/output.c (prepare): Define muscle file_name_all_but_ext as
4036 all_but_ext.
4037 For pkgdatadir muscle, maintain previous functionality by using
4038 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
4039 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
4040 digraphs would never be expanded. Hopefully no one has M4-special
4041 characters in his Bison installation path.
4042 * src/scan-skel.l: Don't parse @output_header_name@ and
4043 @output_parser_name@ anymore since they're now redundant.
4044 In @output, use decode_at_digraphs.
4045 Parse a new @basename command that invokes last_component.
4046 (decode_at_digraphs): New.
4047 (BASE_QPUTS): Remove unused.

4380 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
4381 like $@n instead of just @n so that the default %destructor/%printer
4382 logic doesn't see them as user-defined symbols.

4385 name for which the midrule value is referenced in any action.

4397 all actions have already been scanned in order to set `used' flags.
4398 Otherwise, checking that a midrule's $$ is set will not always work
4399 properly because the midrule check must forward-reference the midrule's

4908 Whether the default %destructor/%printer applies to a particular symbol
4909 isn't a question of whether the user *declares* that symbol (in %token,
4910 for example). It's a question of whether the user by any means
4911 *defines* the symbol at all (by simply using a char token, for
4912 example). $end is defined by Bison whereas any other token with token
4913 number 0 is defined by the user. The error token is always defined by
4914 Bison regardless of whether the user declares it with %token, but we
4915 may one day let the user define error as a nonterminal instead.

5437 * src/scan-code.l (handle_action_dollar): Now that this is invoked
5438 after parsing the entire grammar file, the symbol list here in the case
5439 of a midrule is actually the midrule's empty RHS, so reference its
5440 parent rule's RHS where necessary.
5441 On the other hand, now that you can already know it's a midrule, you

5953 (using GNU make) does not worry about configuring gzip. This also
5954 works around a bug reported independently by Keith Thompson and by

5969 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
5970 state before an empty RHS is always resolved here. Only the location
5971 of that state is guaranteed to be resolved, and that's enough. This
5972 fixes the remaining bug reported by Derek M. Jones in
5973 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
5974 * tests/glr-regression.at (Uninitialized location when reporting
5975 ambiguity): Test the above case.
5976 Also, the embedded comments in this test case claim it checks the case
5977 of an empty RHS that has inherited the initial location. However, the
5978 corresponding LHS was already resolved, so yyresolveLocations didn't
5979 actually have reason to modify it. Fix this by forcing
5980 nondeterministic operation at the beginning of the parse.

6399 During deterministic GLR operation, user actions should be able to
6400 influence the parse by changing yychar. To make this easier to fix and

6429 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
6430 got from <http://bro-ids.org/download.html>. The bug is that
6431 when two actions appeared in succession, the second one was
6432 scanned before the first one was added to the grammar rule
6433 as a midrule action. Bison then output the incorrect warning
6434 "parse.y:905.17-906.36: warning: unused value: $3".

6697 In the yychar entry, remove mention of the local yychar case (pure
6698 parser) since this is irrelevant information when writing semantic
148d66d8 6699 actions and since it's already discussed in `Table of Symbols' where

6700 yychar is otherwise described as an external variable.
6701 In the yychar entry, don't call it the `current' look-ahead since it

6704 actions.

6709 yyclearin.

6724 Allocate, deallocate, resize, and otherwise shuffle space for

6726 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
6727 appropriately during nondeterministic operation.
6728 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
6729 members to store the current lookahead to be used by the deferred

6763 * data/glr.c (yyresolveValue): When merging semantic options, if at
6764 least one user action succeeds but a later one cuts the parse, then
6765 destroy the semantic value before returning rather than leaking it.
6766 (yyresolveStates): If a user action cuts the parse and thus
6767 yyresolveValue fails, ignore the (unset) semantic value rather than
6768 corrupting the yyGLRState, and empty the semantic options list since
6769 the user actions should have called all necessary destructors.

7904 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
7905 that the byte '\0xff' is not printable in the C locale; it is,
7906 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
7907 not printable, so use '\0x81' to test.

8074 * tests/cxx-type.at: Don't pipe output of ./types through sed to
8075 remove trailing spaces. This loses the exit status of ./types,
8076 and isn't needed since ./types shouldn't be emitting trailing
8077 spaces.
8078 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,

8139 eases translation.

8162 Fix typos in explanations of the runtime file.
8163 * bootstrap: Change gettext keyword from YYI18N to YY_.
8164 Use standard Makefile.in.in in runtime-po, since we'll arrange
8165 for backward-compatible bison-runtime.po files in a different way.
8166 * data/glr.c (YY_): New macro, from yacc.c.
8167 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
8168 Translate messages intended for users.
8169 (yyreportSyntaxError): Change "virtual memory" to "memory" to match

8171 is virtual.

8178 Move defn to a more logical place, to be consistent with other
8179 skeletons.

8181 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
8182 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
8183 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
8184 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.

8372 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
8373 so that we also get calc++-parser.yy. Geneate it.
8374 Use $(AWK), not gawk, since any conforming Awk will do.

8403 never had any % directives, we can simply pass it to yyerror.

8405 be modified later, as that is the usual style in glr.c.

8411 in case the user prolog sets feature-test macros like _GNU_SOURCE.

8414 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
8415 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
8416 so that we don't have to maintain their signatures.
8417 (yyFail): Check for buffer overflow, by using vsnprintf rather
8418 than vsprintf. Allocate a bigger buffer if possible.
8419 Report an error if buffer allocation fails.
8420 (yyStackOverflow): New function.
8421 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
8422 the initialization was successful. It might fail if storage was
8423 exhausted.
8424 (yyexpandGLRStack): Add more checks for storage allocation failure.
8425 Use yyStackOverflow to report failures.
8426 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
8427 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
8428 Don't assume stack number fits in int.
8429 (yysplitStack): Check for storage allocation failure.
8430 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
8431 can print diagnostics on storage allocation failure. All callers
8432 changed.
8433 (yyresolveValue): Use yybool for boolean.
8434 (yyreportSyntaxError): Check for size-calculation overflow.
8435 This code is taken from yacc.c.

8437 the initial stack.

9388 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
9389 whether the reducion was empty or not. This leaves room to
9390 improve the use of YYLLOC_DEFAULT in such a case.
9391 lalr1.cc is still experimental, so changing this is acceptable.

9530 output the location within the %printer.

9539 Bison directive from the Bison file to the invocation of this
9540 macro, so that these directives are passed to
9541 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
9542 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
9543 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
9544 the extra Bison directives instead of the whole series.
9545 Change the grammar so that there are recoverable errors, and
9546 unrecoverable errors. Now we can have the parser give up before
9547 consuming the whole input. As a result we now can observe that
9548 the lookahead is freed when needed.
9549 Change the parser source to parse argv[1] instead of a hard coded
9550 string.
9551 Simplify yylex, and give a value and location to EOF.
9552 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
9553 passed directives already coded in the file.
9554 Add some tests to check the location of "error".
9555 For some tests, the C++ parser is correct, and not yacc.c.
9556 For other tests, they provide different, but unsatisfying, values,
9557 so keep the C++ value so that at least one parser is "correct"
9558 according to the test suite.
9559 (Actions after errors): Remove, this is subsumed by the
9560 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

9738 Spent a few hours checking out which prerequisite versions the

9740 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
9741 a seemingly endless set of combinations of versions more recent
9742 than that. The bottom line is that the current sources require
9743 fairly recent versions of the build tools, and it'll be some work

10260 When reducing initial empty rules, Bison parser read an initial
10261 location that is not defined. This results in garbage, and that
10262 affects Bison's own parser. Therefore we need (i) to extend Bison

10557 Fix a GLR parser bug I reported in February; see

10559 The problem was that GLR parsers did not conform to the C standard,
10560 because actions like { $1 = $2 + $3; } expanded to expressions
10561 that invoked YYFILL in separate subexpressions, and YYFILL assigned
10562 to a local variable. The C standard says that expressions
10563 like (var = f ()) + (var = f ()) have undefined behavior.
10564 Another problem was that GCC sometimes issues warnings that
10565 yyfill and its parameters are unused.
10566
10567 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
10568 as possibly unused.
10569 (yyfill): New function.
10570 (YYFILL): Use it.
10571 (yyuserAction): Change type of yynormal to bool, so that it matches
10572 the new yyfill signature. Mark it as possibly unused.

10575 Follow up on a bug I reported in February, where a Bison-generated
10576 parser can loop. Provide a test case and a fix for yacc.c. I
10577 don't have a fix for lalr1.cc or for glr.c, unfortunately.
10578 The original bug report is in:

10581 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
10582 macro's size was becoming unwieldy.
10583 (yyerrlab): Do not discard an empty lookahead symbol, as this
10584 might destroy garbage.
10585 (yyerrorlab): New label, with the old contents of YYERROR,
10586 plus the following change: pop the stack of rhs corresponding
10587 to the production that invoked YYERROR. That is how Yacc
10588 behaves, and POSIX requires this behavior.
10589 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
10590 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
10591 Define 'alarm' to do nothing if unistd.h is not available.
10592 Add a new rule "exp: '-' error;" to test the above change to
10593 data/yacc.c. Use 'alarm' to abort any test taking longer than
10594 10 seconds, as it's probably looping.
10595 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
10596 Also, the new yacc.c generates two fewer diagnostics for an
10597 existing test.

11228 time YYERROR is invoked, but the upside is that the warnings
11229 should vanish.
11230 (yyerrlab1): Move code to YERROR.
11231 (yyerrlab2): Remove. Change uses back to yyerrlab1.
11232 This reverts some of the 2002-12-27 change.

11248 explicitly, as is the case in yacc.c; it is not a problem, as
11249 these elements have fake values.

11363 so that we don't assume that "," has the same interpretation in

11365 (conflicts_output): Use Yacc-style conflict report for each state,

11383 This problem was originally reported by Paul Hilfinger in

11386 * data/yacc.c (yyparse): New local var yylerrsp, to record the
11387 top of the location stack's error locations.
11388 (yyerrlab): Set it. When discarding a token, push its location
11389 onto yylerrsp so that we don't lose track of the error's end.
11390 (yyerrlab1): Now is only the target of YYERROR, so that we can
11391 properly record the location of the action that failed. For GCC
11392 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
11393 GCC warning about yyerrlab1 being unused if YYERROR is unused.
11394 (yyerrlab2): New label, which yyerrlab now falls through to.
11395 Compute the error's location by applying YYLLOC_DEFAULT to
11396 the locations of all the symbols that went into the error.
11397 * doc/bison.texinfo (Location Default Action): Mention that
11398 YYLLOC_DEFAULT is also invoked for syntax errors.
11399 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

11458 If the user does not define YYSTYPE as a macro, Bison now declares it
11459 using typedef instead of defining it as a macro. POSIX requires this.
11460 For consistency, YYLTYPE is also declared instead of defined.
11461
11462 %union directives can now have a tag before the `{', e.g., the
11463 directive `%union foo {...}' now generates the C code
11464 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
11465 The default union tag is `YYSTYPE', for compatibility with Solaris 9
11466 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
11467 instead of `yyltype'.
11468
11469 `yystype' and `yyltype' are now obsolescent macros instead of being
11470 typedefs or tags; they are no longer documented and will be
11471 withdrawn in a future release.

11479 for backward compatibility.
11480 * data/yacc.c: Likewise.
11481
11482 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
11483 does not specify a union tag. This is for compatibility with
11484 Solaris 9 yacc.
11485
11486 * src/parse-gram.y (add_param): 2nd arg is now char * not char

11505 to return when scanning braced code.

12459 Revamp to fix many (but not all) of the C- and M4-related quoting

12464 Use new @ escapes consistently. Represent brackets with @{ and @}
12465 rather than @<:@ and @:>@, since this works a bit better with dumb
12466 editors like vi. Represent @ with @@, since @ is now consistently
12467 an escape. Use @oline@ and @ofile@ rather than __oline__ and
12468 __ofile__, to avoid unexpected expansions. Similarly, use @output
12469 rather than #output.
12470
12471 * data/c.m4 (b4_copyright): Omit file name from comment, since
12472 the file name could contain "*/".
12473 (b4_synclines_flag): Don't quote the 2nd argument; it should already
12474 be quoted. All uses changed.

12477 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
12478 b4_output_header_suffix, b4_output_header_name, b4_header_guard):

12488 mishandled funny characters in file names, and anyway it isn't
12489 needed any more.
12490 * data/yacc.c: Likewise.
12491 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.

12502 (prepare_symbols): Quote tokens for M4.
12503 (prepare): Don't insert output_infix, output_prefix,
12504 output_parser_name, output_header_name; this is now down by scan-skel.
12505 Insert skeleton as a C string.
12506

12511 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
12512 escapes other than \\ and \'; this simplifies the code.

12514 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
12515 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
12516 Use new escapes @{ and @} for [ and ].
12517
12518 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
12519 them with auto vars.
12520 Switch to new escape scheme, where @ is the escape character uniformly.
12521 Abort if a stray escape character is found. Avoid unbounded input
12522 buffer when parsing non-escaped text.
12523
12524 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
12525 __oline__, #output, $@, and @{ do not have unintended meanings.

12533 table.
12534 (yygetLRActions, yyrecoverParseError): Use them.
12535
12536 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
12537 counted in the token inserted at end of file. Now takes
12538 location_t *, not location_t, so that the location can be
12539 adjusted. All uses changed.
12540

12542 diagnostic to match the new behavior.

12545 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
12546 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
12547 abort ();'. This reduces the runtime of the "Many lookaheads"
12548 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running

12749 Use {splice} wherever C allows backslash-newline.
12750 YY_STEP after space, newline, vertical-tab.

PE
12758 (YY_STEP): Omit trailing semicolon, so that it's more like C.
12759

12761 as well as \000. Check for UCHAR_MAX, not 255.
12762 Allow \x with an arbitrary positive number of digits, as in C.
12763 Check for overflow here.
12764 Allow \? and UCNs, for compatibility with C.

12766 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
12767 with quote slot used by complain_at.

12770 in symbols, long literals, and funny escapes in strings.

12804 Check for close failures.
12805 * src/files.h (xfclose): Return void, not int, since it always
12806 returned zero.
12807 * src/files.c (xfclose): Likewise. Report I/O error if ferror
12808 indicates one.
12809 * src/output.c (output_skeleton): Use xfclose rather than fclose

12811
12812 * data/glr.c (YYLEFTMOST_STATE): Remove.

12831 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
12832 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
12833 we use malloc. Don't assume 'A' through 'Z' are contiguous.
12834 Don't assume strdup exists; POSIX says its an XSI extension.

12873 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
12874 decl; not needed any more.
12875 * src/main.c (main): Use return to exit, undoing yesterday's change.
12876 The last OS that we could find where this wouldn't work is
12877 SunOS 3.5, and that's too old to worry about now.
12878
12879 * data/glr.c (struct yyltype): Define members even when not
12880 doing locations. This is more consistent with yacc.c, and it
12881 works around the following bug reports:

12895 Be consistent about 'bool'; the old code used an enum in one
12896 module and an int in another, and this violates the C standard.
12897 * m4/stdbool.m4: New file, from coreutils 4.5.3.
12898 * configure.ac (AC_HEADER_STDBOOL): Add.
12899 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.

12924 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
12925 * src/getargs.c (usage): Likewise.
12926

12941 Include <limits.h> unconditionally, since it's guaranteeed even

13118 Stop using the "enum_" trick for K&R-style function definitions;
13119 it confused me, and I was the author! Instead, assume that people

13253 Let nondeterministic skeletons be usable with deterministic
13254 tables.
13255
13256 With the patch, GAWK compiled by GCC without -O2 passes its test
13257 suite using a GLR parser driven by LALR tables. It fails with -O2
13258 because `struct stat' gives two different answers on my machine:
13259 88 (definition of an auto var) and later 96 (memset on this var).
13260 Hence the stack is badly corrumpted. The headers inclusion is to
13261 blame: if I move the awk.h inclusion before GLR's system header
13262 inclusion, the two struct stat have the same size.

16709 not visible.

16727 Don't use %option yylineno: it seems that then Flex imagines
16728 REJECT has been used, and therefore it won't reallocate its
16729 buffers (which makes no other sense to me than a bug). It results
16730 in warnings for `unused: yy_flex_realloc'.

16928 harmless).

17037 (generate_states): Adjust.
17038 * src/print.c: When reporting a rule number to the user, substract
17039 1, so that the axiom rule is rule 0, and the first user rule is 1.
17040 * src/reduce.c: Likewise.

17045 0: `$axiom: START-SYMBOL $'.

17072 (parse_token_decl): If the token being defined has value `0', it
17073 is the eoftoken.
17074 (packsymbols): No longer hack `tags' to insert `$' by hand.
17075 Be sure to preserve the value of the eoftoken.
17076 (reader): Make sure eoftoken is defined.
17077 Initialize nsyms to 0: now eoftoken is created just like the others.
17078 * src/print.c (print_grammar): Don't special case the eof token.
17079 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
17080 lie anyway, albeit pleasant.
17081 * tests/calc.at: Exercise error messages with eoftoken.
17082 Change the grammar so that empty input is invalid.

17923 Because useless nonterminals are now kept alive (instead of being

17933 `shift_symbol', containing the symbol that can be shifted from a
17934 given state.
17935 Deobfuscate, i.e., allocate, use and free `symbol_count' here

18518 * tests/calc.at, tests/output.at, tests/regression.at,
18519 * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
18520 now the tests are run in private dirs, therefore AC_CLEANUP and
18521 family can be simplified to 0-ary.
18522 * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
18523 use abs. path to find config.h.
18524 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's
18525 stderr, there can be way too much random noise.

18547 * src/lex.c (parse_percent_token): Replace equal_offset with
18548 arg_offset.
18549 arg is const.
18550 Be sure to strdup `arg' when used, since there is no reason for

20319 The location tracking mechanism is precious for parse error
20320 messages. Nevertheless, it is enabled only when `@n' is used in
20321 the grammar, which is a different issue (you can use it in error

20323 be another means to enable it.

20355 Test also `--verbose', `--defines' and `--name-prefix'. Testing
20356 the latter demonstrates a flaw in the handling of non debugging
20357 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
20358 was used in order to simplify:
20359
20360 #if YYDEBUG
20361 if (yydebug)
20362 {

20369 if (yydebug)
20370 {
20371 ...
20372 }
20373
20374 unfortunately this leads to a CPP conflict when

20426 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
20427 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
20428 difficult and introduced a lot of core dump. It turns out that
20429 Bison used an implementation of `xmalloc' based on `calloc', and
20430 at various places it does depend upon the initialization to 0. I
20431 have not tried to isolate the pertinent places, and all the former
20432 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,

21521 declaration to allow a multi-character symbol as an alias.
21522 (parse_thong_decl): New function.

21533 Revised and use multiple warnxxx functions to avoid using VARARGS1.
21534 (read_declarations): Improve the error message for
21535 an invalid character. Do not abort.
21536 (read_declarations, copy_guard, copy_action): Use
21537 printable_version to avoid unprintable characters in printed output.

21560 Include getopt.h. Add some extern decls.
21561 (safegetc): New function to deal with EOF gracefully.
21562 (literalchar); new function to deal with reading \ escapes.
21563 (lex): Use literalchar.
21564 (lex): Implemented "..." tokens.
21565 (literalchar, lex, parse_percent_token): Made tokenbuffer
21566 always contain the token. This includes growing the token
21567 buffer while reading an integer.
21568 (parse_percent_token): Replaced if-else statement with percent_table.
21569 (parse_percent_token): Added % declarations as another
21570 way to specify the flags -n, -l, and -r. Also added hooks for
21571 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
21572 major changes to files.c.
21573 (lex) Retain in the incoming stream a character following
21574 an incorrect '/'.
21575 (skip_white_space, lex): Revised most error messages
