43 Make xml2dot.xsl and --graph produce the same output.
44 * data/xslt/xml2dot.xsl (xsl:template match="rule"): Use a `&#10;'
45 instead of a `\n'. That is, don't add escapes yet or they'll be doubly
46 escaped later.
47 (xsl:template name="output-node"): Use the new escape template instead
48 of the string-replace template directly.
49 (xsl:template name="output-edge"): Likewise.
50 (xsl:template name="escape"): New, escapes backslashes and newlines in
51 addition to quotation marks.
52 * src/graphviz.c (start_graph, output_node, output_edge): Add
53 whitespace to output for legibility.
54
55 Make xml2text.xsl and --report produce the same output, and remove the
56 XML "conflicts" element since a conflict summary is easily extracted
57 from the automaton.
58 * data/xslt/bison.xsl: New.
59 (xsl:template match="state" mode="bison:count-conflicts): New.
60 * data/xslt/xml2text.xsl: Import bison.xsl.
61 (xsl:template match="bison-xml-report"): Instead of styling the
62 "conflicts" element, style the "automaton" element with mode
63 "conflicts". Unlike the former, the latter lists S/R and R/R
64 conflicts for a state on the same line.
65 (xsl:template match="conflicts"): Remove.
66 (xsl:template match="conflict"): Remove.
67 (xsl:template match="terminal"): Line-wrap the list of rules in which
68 the terminal is used.
69 (xsl:template match="nonterminal"): Likewise for nonterminals.
70 (xsl:template match="automaton" mode="conflicts"): New.
71 (xsl:template match="state" mode="conflicts"): New.
72 (xsl:template name="line-wrap"): New.
73 (xsl:template name="ws-search"): New.
74 * data/xslt/xml2xhtml.xsl: Import bison.xsl.
75 (xsl:template match="bison-xml-report"): Instead of styling the
76 "conflicts" element, style the "automaton" element with mode
77 "conflicts."
78 (xsl:template match="conflicts"): Remove.
79 (xsl:template match="conflict"): Remove.
80 (xsl:template match="automaton" mode="conflicts"): New.
81 (xsl:template match="state" mode="conflicts): New.
82 * src/conflicts.c (conflicts_output_xml): Remove.
83 * src/conflicts.h (conflicts_output_xml): Remove prototype.
84 * src/print-xml.c (print_xml): Don't invoke conflicts_output_xml.
85 * src/print.c (print_grammar): Consistently wrap at the 66th column so
86 the corresponding XSLT is easier. Also, never wrap between a word and
87 the comma that follows it.

91 Improve C++ namespace support. Discussed starting at
92 <http://lists.gnu.org/archive/html/help-bison/2007-09/msg00016.html>.
93 * data/c++.m4: (b4_namespace_ref, b4_namespace_open,
94 b4_namespace_close): New macros that interpret the %define variable
95 "namespace" so its value can contain "::" to indicate nested
96 namespaces.
97 * data/glr.cc (b4_namespace): Don't define, and replace all uses with
98 the above macros.
99 * data/lalr1.cc (b4_namespace): Likewise.
100 * data/location.cc (b4_namespace): Likewise.
101 * doc/bison.texinfo (Decl Summary): Move `%define push_pull' entry
102 inside a new table in the general %define entry. Document `%define
103 namespace' there as well. Point the %name-prefix entry to it since it
104 explains it more completely in the case of C++.
105 (C++ Bison Interface): Mention `%define namespace' instead of
106 %name-prefix.
107 (Table of Symbols): Remove the `%define push_pull' entry. The %define
108 entry suffices.
109 * tests/c++.at (Relative namespace references): New test case.
110 (Absolute namespace references): New test case.
111 (Syntactically invalid namespace references): New test case.
112 * tests/input.at (C++ namespace reference errors): New test case.

117 interfaces.
118 * data/bison.m4 (b4_percent_define_get_loc): New.
119 (b4_percent_define_get_syncline): New.
120 (b4_percent_define_flag_if): Use b4_percent_define_get_loc.
121 (b4_percent_define_default): Record defining location as line 1 rather
122 than 0 for the sake of synchronizing #line's, and define
123 b4_percent_define_syncline(VARIABLE).
124 (b4_percent_define_check_values): Use b4_percent_define_get_loc.
125 * src/muscle_tab.c (muscle_syncline_grow): New.
126 (muscle_code_grow): Use muscle_syncline_grow.
127 (muscle_percent_define_insert): Use muscle_percent_define_get_loc, and
128 define b4_percent_define_syncline(VARIABLE).
129 (muscle_percent_define_get_loc): New.
130 (muscle_percent_define_get_syncline): New.
131 (muscle_percent_define_flag_if): Use muscle_percent_define_get_loc, and
132 remove some unused variables.
133 (muscle_percent_define_default): Record defining location as line 1
134 rather than 0 for the sake of synchronizing #line's, and define
135 b4_percent_define_syncline(VARIABLE).
136 (muscle_percent_define_check_values): Use
137 muscle_percent_define_get_loc.

140 * tests/skeletons.at (%define Boolean variables: invalid skeleton
141 defaults): Update output for location change.

147 Fix some error-reporting macro bugs.
148 * data/bison.m4 (b4_cat): New.
149 (b4_error, b4_error_at): Use b4_cat to send error directives directly
150 to stdout so they don't become arguments to other macros. Update
151 comments and add examples.
152 (b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and
153 add examples.
154 (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately
155 after printing the error directive so that M4 doesn't report subsequent
156 problems that are induced by this problem.
157 * src/scan-skel.l: Recognize @` digraph outside of directive arguments
158 instead of just in them. Recognize @\n in both places. Both expand to
159 the empty string. Needed by b4_cat.
160 * tests/skeletons.at (Complaining during macro argument expansion):
161 New test case.
162 (Fatal errors make M4 exit immediately): New test case.

187 Replace `%push-parser' and `%push-pull-parser' with

191 Pull Parser Function, Parser Create Function, Parser Delete Function):
192 Update declarations.
193 (Decl Summary, Table of Symbols): Replace %push-parser and

197 definitions...
198 * data/c.m4 (b4_identification): ... and the YYPUSH and YYPULL cpp
199 definitions...
200 * data/push.c: ... to here and compute them from the value of the
201 %define variable push_pull.
202 * data/c-skel.m4: Instead of choosing the push.c skeleton for push
203 parsing requests here...
204 * data/yacc.c: ... hack this to switch to push.c any time
205 b4_use_push_pull_flag or the %define variable push_pull is set. This
206 will go away when we mv push.c yacc.c.
207 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
208 push parsing is not supported since unused %define variables are
209 reported anyway.
210 * src/getargs.c, src/getargs.h (pull_parser, push_parser): Remove.
211 * src/muscle_tab.h (muscle_percent_define_check_values): Update

553 move the check for disabled transitions to an aver since conflict
554 resolution hasn't happened yet.
555
556 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
557 labels a state as inconsistent just because it has error transitions.
558 The original form of this check appeared in revision 1.1 of lalr.c,
559 which was committed on 1991-12-21. Now (at least), changing the
560 consistency label on such a state appears to have no useful effect in
561 any of the places it is examined, which I enumerate below. The key
562 point to understanding each item in this enumeration is that a state
563 with an error transition is labelled consistent in the first place only
564 if it has no rules, so the check cannot matter for states that have
565 rules. (1) Labelling a state as inconsistent will cause set_conflicts
566 to try to identify its conflicts, and a state must have *rules* to have
567 conflicts. (2) Labelling a state as inconsistent will affect how
568 action_row sets the default *rule* for the state. (3) Labelling a
569 state as inconsistent will cause build_relations to add lookback edges
570 to *rules* in that state.

572 more carefully.

827 Undo my 2007-02-07 change, switching back to the c-strcase module
828 introduced in the 2007-02-03 change. Bruno Haible reported that
829 the 2007-02-07 change would be dangerous in Turkish if we add a
830 language whose name contains "i", since "i" is not lowercase "I"
831 in Turkish.

1081 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use

1085 macro named `b4_percent_define(foo)'; expect any %code blocks for the
1086 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
1087 expect any unqualified %code blocks to be stored in a macro named
1088 `b4_percent_code_unqualified'.
1089 Use m4_indir so that %define variable names and %code qualifiers can
1090 contain `.', which is allowed by the grammar parser.
1091 (b4_percent_define_default): New macro to set a default value for a
1092 %define variable.
1093 (m4_wrap): Update wrapped code, and fix some underquoting.
1094 (b4_check_user_names_wrap): Update and define outside the m4_wrap.

1097 b4_percent_code_user_qualifiers.

1210 Instead of having skeletons declare all valid %define variables and
1211 %code qualifiers, provide macros that retrieve the associated values
1212 and build these lists automatically. Thus Bison will now warn when a
1213 variable or qualifier is not used by the skeleton in the current
1214 invocation regardless of whether it might sometimes be used by that
1215 skeleton in other invocations. Also, move all %define value macros to
1216 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
1217 form, which is replaced by %code.
1218 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
1219 (b4_check_user_names): ... this, and change the series of valid name
1220 arguments to a single list argument for names used in the skeleton
1221 similar to the existing list argument for names used in the grammar.
1222 Warn instead of complaining.
1223 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
1224 values and %code code, to format %code code properly, and to build
1225 lists of all %define variables and %code qualifiers used in the
1226 skeleton: b4_skeleton_percent_define_variables and
1227 b4_skeleton_percent_code_qualifiers.
1228 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
1229 Remove, and...
1230 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
1231 the skeleton names lists can finish building first. In place of
1232 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
1233 expect the lists b4_user_percent_define_variables and
1234 b4_user_percent_code_qualifiers.
1235 * data/c++.m4: Where setting default values for b4_parser_class_name,
1236 b4_location_type, b4_filename_type, b4_namespace, and
1237 b4_define_location_comparison, update their names to the
1238 b4_percent_define_ namespace.
1239 * data/glr.c: Don't use b4_check_percent_define_variables and
1240 b4_check_percent_code_qualifiers. Use b4_get_percent_code.

1248 b4_use_push_for_pull_if or m4_wrap code will never execute.
1249 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
1250 Rename to...
1251 (muscle_grow_user_name_list): ... this for consistency with the
1252 terminology used in bison.m4.
1253 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
1254 %define variable names, and rename muscle used_percent_define_variables
1255 to user_percent_define_variables.
1256 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
1257 user_percent_code_qualifiers.

1356 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
1357 the previous removal of uses of m4_divert, which caused trouble.

1679 Enable push parsers to operate in impure mode. Thus, %push-parser no
1680 longer implies %pure-parser. The point of this change is to move
1681 towards being able to test the push parser code by running the entire
1682 test suite as if %push-parser had been declared.
1683 * data/push.c (yypush_parse): For impure mode, remove the
1684 yypushed_char, yypushed_val, and yypushed_loc arguments.
1685 Instead, declare these as local variables initialized to the global
1686 yychar, yylval, and yylloc.
1687 For the first yypush_parse invocation only, restore the initial values
1688 of these global variables when it's time to read a token since they
1689 have been overwritten.
1690 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
1691 %push-parser.
1692 * tests/calc.at (Simple LALR(1) Calculator): Always declare

1737 initialized (with b4_location_initial_line and
1738 b4_location_initial_column) upon calling yypush_parse. However, that
1739 initialization now overwrites the first token's location;
1740 %initial-action assigning @$ already did the same thing, and both bugs
1741 will be fixed in a later patch.

1949 Fix a couple of bugs related to special characters in user-specified
1950 file names, and make it easier for skeletons to compute output file
1951 names with the same file name prefix as Bison-computed output file
1952 names.
1953 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
1954 b4_parser_file_name and b4_spec_defines_file instead of
1955 @output_parser_name@ and @output_header_name@, which are now redundant.
1956 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
1957 b4_parser_file_name, b4_spec_defines_file, and the new
1958 @basename(FILENAME@) instead of @output_parser_name@ and
1959 @output_header_name@, which inappropriately escaped the file names as
1960 C string literals.
1961 * src/files.c (all_but_ext): Remove static qualifier.
1962 (compute_output_file_names): Move `free (all_but_ext)' to...
1963 (output_file_names_free): ... here since all_but_ext is needed later.
1964 * src/files.h (all_but_ext): Extern.
1965 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
1966 exactly what MUSCLE_INSERT_STRING used to do.
1967 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
1968 characters are escaped properly.
1969 * src/output.c (prepare): Define muscle file_name_all_but_ext as
1970 all_but_ext.
1971 For pkgdatadir muscle, maintain previous functionality by using
1972 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
1973 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
1974 digraphs would never be expanded. Hopefully no one has M4-special
1975 characters in his Bison installation path.
1976 * src/scan-skel.l: Don't parse @output_header_name@ and
1977 @output_parser_name@ anymore since they're now redundant.
1978 In @output, use decode_at_digraphs.
1979 Parse a new @basename command that invokes last_component.
1980 (decode_at_digraphs): New.
1981 (BASE_QPUTS): Remove unused.
1982 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.

2842 Whether the default %destructor/%printer applies to a particular symbol
2843 isn't a question of whether the user *declares* that symbol (in %token,
2844 for example). It's a question of whether the user by any means
2845 *defines* the symbol at all (by simply using a char token, for
2846 example). $end is defined by Bison whereas any other token with token
2847 number 0 is defined by the user. The error token is always defined by
2848 Bison regardless of whether the user declares it with %token, but we
2849 may one day let the user define error as a nonterminal instead.
2850 * NEWS (2.3+): Say "user-defined" instead of "user-declared".

3371 * src/scan-code.l (handle_action_dollar): Now that this is invoked
3372 after parsing the entire grammar file, the symbol list here in the case
3373 of a midrule is actually the midrule's empty RHS, so reference its
3374 parent rule's RHS where necessary.
3375 On the other hand, now that you can already know it's a midrule, you

3887 (using GNU make) does not worry about configuring gzip. This also
3888 works around a bug reported independently by Keith Thompson and by
3889 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
3890 stderr rather than stdout, messing up the build logs.

3903 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
3904 state before an empty RHS is always resolved here. Only the location
3905 of that state is guaranteed to be resolved, and that's enough. This
3906 fixes the remaining bug reported by Derek M. Jones in
3907 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
3908 * tests/glr-regression.at (Uninitialized location when reporting
3909 ambiguity): Test the above case.
3910 Also, the embedded comments in this test case claim it checks the case
3911 of an empty RHS that has inherited the initial location. However, the
3912 corresponding LHS was already resolved, so yyresolveLocations didn't
3913 actually have reason to modify it. Fix this by forcing
3914 nondeterministic operation at the beginning of the parse.

4333 During deterministic GLR operation, user actions should be able to
4334 influence the parse by changing yychar. To make this easier to fix and
4335 to make glr.c easier to evolve in general, don't maintain yytoken in

4363 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
4364 got from <http://bro-ids.org/download.html>. The bug is that
4365 when two actions appeared in succession, the second one was
4366 scanned before the first one was added to the grammar rule
4367 as a midrule action. Bison then output the incorrect warning
4368 "parse.y:905.17-906.36: warning: unused value: $3".
4369 * src/parse-gram.y (BRACED_CODE, action): These are no longer
4370 associated with a value.

4654 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to
4655 use during nondeterministic operation to track which stacks have
4656 actually needed the current lookahead.
4657 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack):
4658 Allocate, deallocate, resize, and otherwise shuffle space for
4659 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
4660 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
4661 appropriately during nondeterministic operation.
4662 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
4663 members to store the current lookahead to be used by the deferred
4664 user action.
4665 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
4666 from which the RHS is taken. Set the lookahead members of the new
4667 yySemanticOption according to the lookahead status for stack yyk.
4668 (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to
4669 yyaddDeferredAction.
4670 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead
4671 members of yySemanticOption before invoking yyuserAction, and then set
4672 them back to their current values afterward.

4697 * data/glr.c (yyresolveValue): When merging semantic options, if at
4698 least one user action succeeds but a later one cuts the parse, then
4699 destroy the semantic value before returning rather than leaking it.
4700 (yyresolveStates): If a user action cuts the parse and thus
4701 yyresolveValue fails, ignore the (unset) semantic value rather than
4702 corrupting the yyGLRState, and empty the semantic options list since
4703 the user actions should have called all necessary destructors.
4704 Simplify code with YYCHK.

4706 cuts parse): New test case.

5818 reported by Joel E. Denny in
5819 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
5820 (trivial change).
5821 * tests/glr-regression.at (Duplicate representation of merged trees):
5822 New test, from Joel E. Denny in:

5835 * tests/regression.at (Token definitions): Don't rely on
5836 AT_PARSER_CHECK for data that contains backslashes. It currently
5837 uses 'echo', and 'echo' isn't portable if its argument contains
5838 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
5839 that the byte '\0xff' is not printable in the C locale; it is,
5840 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
5841 not printable, so use '\0x81' to test.

5856 Add __attribute__ ((__noreturn__)).

5859 "make maintainer-distcheck".

5898 it's error-prone and "make maintainer-distcheck" rejects it.

5939 "make maintainer-distcheck" complained about.

5942 and omit line-number decoration that makes Emacs compile think
5943 that informative messages are worth worrying about.

5952 autogenerated by the maintainer.
5953 * examples/calc++/.cvsignore: Add *.yy.
5954
5955 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.

5962 from maintainer-distcheck about casting the argument of 'free'.
5963
5964 * NEWS: Mention recent yytname changes.
5965 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.

5967 * bootstrap: For translations that have not yet been upgraded to
5968 the new runtime-po domain, prime the pump by extracting the
5969 relevant strings from the obsolete translations. This code can be
5970 removed once the bison-runtime domain has been translated by each
5971 team.
5972
5973 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
5974 now that token names are already quoted.

5977 * data/glr.c (YYTOKEN_TABLE): New macro.

5990 (yyreportSyntaxError): Use it to dequote most string literals.

5997 * doc/bison.texinfo (Decl Summary, Calling Convention):
5998 Clarify quoting convention of yytname.
5999 * src/output.c (prepare_symbols): Quote all names. This undoes
6000 the 2005-04-17 change, which is now accomplished (mostly) via
6001 changes in the parsers as described above.
6002 * tests/regression.at (Token definitions, Web2c Actions):
6003 Undo most 2005-04-17 change here, too.

60052005-07-20 Paul Eggert <eggert@cs.ucla.edu>
6006
6007 Fix more problems reported by twlevo@xs4all.nl.
6008 * tests/cxx-type.at: Don't pipe output of ./types through sed to
6009 remove trailing spaces. This loses the exit status of ./types,
6010 and isn't needed since ./types shouldn't be emitting trailing
6011 spaces.
6012 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
6013 as the stack isn't valid in that case.
6014
6015 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
6016 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
6017 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
6018 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
6019 is used.
6020 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):

6025 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
6026 overly-picky compilers that reject 'char *foo = "bar";'.
6027
6028 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
6029 to FILE * parameter, not to stderr. This fixes a typo introduced
6030 in the 2005-07-12 change.
6031
6032 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
6033 warnings from GCC 4.
6034
6035 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):

6038 (yyglrShift): Remove unused parameters b4_user_formals.

6047 stack before failing, as the cleanup code will do it for us now.
6048 * data/lalr1.cc (yyerrlab): Likewise.
6049 * data/glr.c (yyparse): Pop everything off the stack before
6050 freeing it, so that destructors get called properly.
6051 * data/lalr1.cc (yyreturn): Likewise.
6052 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.

6057 Some English-language cleanups for %destructor.
6058 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

6069 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
6070 Rename yyoverflowab to yyexhaustedlab.
6071 When memory exhaustion occurs during syntax-error reporting,
6072 report it separately rather than in a single diagnostic; this
6073 eases translation.
6074 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.

6084 can be understood only by someone who can read the
6085 (English-language) source code.

6087 Generate runtime-po/bison-runtime.pot automatically, so that we

6092
6093 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
6094 Now auto-generated.
6095 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
6096 Fix typos in explanations of the runtime file.
6097 * bootstrap: Change gettext keyword from YYI18N to YY_.
6098 Use standard Makefile.in.in in runtime-po, since we'll arrange
6099 for backward-compatible bison-runtime.po files in a different way.
6100 * data/glr.c (YY_): New macro, from yacc.c.
6101 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
6102 Translate messages intended for users.
6103 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
6104 the wording in the other skeletons. We don't know that the memory
6105 is virtual.
6106 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
6107 Use same method that yacc.c uses.
6108 Don't translate debugging messages.
6109 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
6110 it doesn't work (yet), and requires C++ expertise to fix.
6111 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
6112 Move defn to a more logical place, to be consistent with other
6113 skeletons.
6114 Don't translate debugging messages.
6115 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
6116 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
6117 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
6118 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.

7322 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
7323 whether the reducion was empty or not. This leaves room to
7324 improve the use of YYLLOC_DEFAULT in such a case.
7325 lalr1.cc is still experimental, so changing this is acceptable.
7326 And finally, there are probably not many users who changed the
7327 handling of locations in GLR, so changing is admissible too.

7464 output the location within the %printer.
7465 Activate GLR tests, at least to make sure they compile properly.

7472 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
7473 Bison directive from the Bison file to the invocation of this
7474 macro, so that these directives are passed to
7475 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
7476 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
7477 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
7478 the extra Bison directives instead of the whole series.
7479 Change the grammar so that there are recoverable errors, and
7480 unrecoverable errors. Now we can have the parser give up before
7481 consuming the whole input. As a result we now can observe that
7482 the lookahead is freed when needed.
7483 Change the parser source to parse argv[1] instead of a hard coded
7484 string.
7485 Simplify yylex, and give a value and location to EOF.
7486 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
7487 passed directives already coded in the file.
7488 Add some tests to check the location of "error".
7489 For some tests, the C++ parser is correct, and not yacc.c.
7490 For other tests, they provide different, but unsatisfying, values,
7491 so keep the C++ value so that at least one parser is "correct"
7492 according to the test suite.
7493 (Actions after errors): Remove, this is subsumed by the
7494 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

7672 Spent a few hours checking out which prerequisite versions the

7674 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
7675 a seemingly endless set of combinations of versions more recent
7676 than that. The bottom line is that the current sources require
7677 fairly recent versions of the build tools, and it'll be some work

7811 on them being in our CVS. Upgrade to latest versions of gnulib
7812 and Automake.

7944 test whether it can stand alone.
7945
7946 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
7947 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
7948 unused declaration.
7949

8067 There's no need to mention top_builddir since Automake does that
8068 for us.

8194 When reducing initial empty rules, Bison parser read an initial
8195 location that is not defined. This results in garbage, and that
8196 affects Bison's own parser. Therefore we need (i) to extend Bison

8491 Fix a GLR parser bug I reported in February; see
161a71f3 8492 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.

8493 The problem was that GLR parsers did not conform to the C standard,
8494 because actions like { $1 = $2 + $3; } expanded to expressions
8495 that invoked YYFILL in separate subexpressions, and YYFILL assigned
8496 to a local variable. The C standard says that expressions
8497 like (var = f ()) + (var = f ()) have undefined behavior.
8498 Another problem was that GCC sometimes issues warnings that
8499 yyfill and its parameters are unused.
8500
8501 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
8502 as possibly unused.
8503 (yyfill): New function.
8504 (YYFILL): Use it.
8505 (yyuserAction): Change type of yynormal to bool, so that it matches
8506 the new yyfill signature. Mark it as possibly unused.
8507

8509 Follow up on a bug I reported in February, where a Bison-generated
8510 parser can loop. Provide a test case and a fix for yacc.c. I
8511 don't have a fix for lalr1.cc or for glr.c, unfortunately.
8512 The original bug report is in:

8514
8515 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
8516 macro's size was becoming unwieldy.
8517 (yyerrlab): Do not discard an empty lookahead symbol, as this
8518 might destroy garbage.
8519 (yyerrorlab): New label, with the old contents of YYERROR,
8520 plus the following change: pop the stack of rhs corresponding
8521 to the production that invoked YYERROR. That is how Yacc
8522 behaves, and POSIX requires this behavior.
8523 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
8524 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
8525 Define 'alarm' to do nothing if unistd.h is not available.
8526 Add a new rule "exp: '-' error;" to test the above change to
8527 data/yacc.c. Use 'alarm' to abort any test taking longer than
8528 10 seconds, as it's probably looping.
8529 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
8530 Also, the new yacc.c generates two fewer diagnostics for an
8531 existing test.

9159 we don't need to worry about yyerrlab1 being reported as an

9179 when the stacks contain one element, as the loop would otherwise
9180 free the last state, and then use the top state (the one we just
9181 popped). This means that the initial elements will not be freed
9182 explicitly, as is the case in yacc.c; it is not a problem, as
9183 these elements have fake values.

9294 * src/conflicts.c (conflict_report):
9295 Renamed from conflict_report_yacc, removing the old
9296 'conflict_report'. Translate the entire conflict report at once,
9297 so that we don't assume that "," has the same interpretation in
9298 all languages.
9299 (conflicts_output): Use Yacc-style conflict report for each state,
9300 instead of our more-complicated style.
9301 (conflicts_print): Use Yacc-style conflict report, except print
9302 the input file name when not emulating Yacc.
9303 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
9304 Conflicted Reduction, %expect not enough, %expect too much,

9317 This problem was originally reported by Paul Hilfinger in

9320 * data/yacc.c (yyparse): New local var yylerrsp, to record the
9321 top of the location stack's error locations.
9322 (yyerrlab): Set it. When discarding a token, push its location
9323 onto yylerrsp so that we don't lose track of the error's end.
9324 (yyerrlab1): Now is only the target of YYERROR, so that we can
9325 properly record the location of the action that failed. For GCC
9326 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
9327 GCC warning about yyerrlab1 being unused if YYERROR is unused.
9328 (yyerrlab2): New label, which yyerrlab now falls through to.
9329 Compute the error's location by applying YYLLOC_DEFAULT to
9330 the locations of all the symbols that went into the error.
9331 * doc/bison.texinfo (Location Default Action): Mention that
9332 YYLLOC_DEFAULT is also invoked for syntax errors.
9333 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
9334 Error locations include the locations of all the tokens that were
9335 discarded, not just the last token.

9392 If the user does not define YYSTYPE as a macro, Bison now declares it
9393 using typedef instead of defining it as a macro. POSIX requires this.
9394 For consistency, YYLTYPE is also declared instead of defined.
9395
9396 %union directives can now have a tag before the `{', e.g., the
9397 directive `%union foo {...}' now generates the C code
9398 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
9399 The default union tag is `YYSTYPE', for compatibility with Solaris 9
9400 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
9401 instead of `yyltype'.
9402
9403 `yystype' and `yyltype' are now obsolescent macros instead of being
9404 typedefs or tags; they are no longer documented and will be
9405 withdrawn in a future release.

9411 (YYLTYPE): Renamed from yyltype.
9412 (yyltype, yystype): New (and obsolescent) macros,
9413 for backward compatibility.
9414 * data/yacc.c: Likewise.
9415
9416 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
9417 does not specify a union tag. This is for compatibility with
9418 Solaris 9 yacc.
9419

9423 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,

9428 (print_token_value): Print contents of bundled tokens.

9437 has (or usually has) an immediately-following braced code.

9439 to return when scanning braced code.

10393 Revamp to fix many (but not all) of the C- and M4-related quoting
10394 problems. Among other things, this fixes the Bison bug reported
10395 by Jan Hubicka when processing the Bash grammar; see:

10398 Use new @ escapes consistently. Represent brackets with @{ and @}
10399 rather than @<:@ and @:>@, since this works a bit better with dumb
10400 editors like vi. Represent @ with @@, since @ is now consistently
10401 an escape. Use @oline@ and @ofile@ rather than __oline__ and
10402 __ofile__, to avoid unexpected expansions. Similarly, use @output
10403 rather than #output.
10404
10405 * data/c.m4 (b4_copyright): Omit file name from comment, since
10406 the file name could contain "*/".
10407 (b4_synclines_flag): Don't quote the 2nd argument; it should already
10408 be quoted. All uses changed.

10410 * data/glr.c: Use new @ escapes consistently.
10411 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
10412 b4_output_header_suffix, b4_output_header_name, b4_header_guard):

10414 names.

10422 mishandled funny characters in file names, and anyway it isn't
10423 needed any more.
10424 * data/yacc.c: Likewise.
10425 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.

10436 (prepare_symbols): Quote tokens for M4.
10437 (prepare): Don't insert output_infix, output_prefix,
10438 output_parser_name, output_header_name; this is now down by scan-skel.
10439 Insert skeleton as a C string.

10446 escapes other than \\ and \'; this simplifies the code.

10448 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
10449 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
10450 Use new escapes @{ and @} for [ and ].
10451
10452 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
10453 them with auto vars.
10454 Switch to new escape scheme, where @ is the escape character uniformly.
10455 Abort if a stray escape character is found. Avoid unbounded input
10456 buffer when parsing non-escaped text.
10457

10459 __oline__, #output, $@, and @{ do not have unintended meanings.

10471 counted in the token inserted at end of file. Now takes
10472 location_t *, not location_t, so that the location can be
10473 adjusted. All uses changed.

10479 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,

10481 abort ();'. This reduces the runtime of the "Many lookaheads"

11187 Let nondeterministic skeletons be usable with deterministic
11188 tables.
11189
11190 With the patch, GAWK compiled by GCC without -O2 passes its test
11191 suite using a GLR parser driven by LALR tables. It fails with -O2
11192 because `struct stat' gives two different answers on my machine:
11193 88 (definition of an auto var) and later 96 (memset on this var).
11194 Hence the stack is badly corrumpted. The headers inclusion is to
11195 blame: if I move the awk.h inclusion before GLR's system header
11196 inclusion, the two struct stat have the same size.

11673 as int, and similarly for yyposn and YYINDEX.

11719 size_t; the old version tried to do this but casted improperly.

11754 manual recommends.
11755 Similarly, use src/scan-gram.l instead of src/scan-gram.c.

11758 (strerror): Use same pattern as ../lib/error.c.

11765 to void, to avoid a GCC warning when --disable-nls is in effect.
11766
11767 * src/scan-gram.l: Use strings rather than escapes when possible,
11768 to minimize the number of warnings from xgettext.
11769 (handle_action_dollar, handle_action_at): Don't use isdigit,
11770 as it mishandles negative chars and it may not work as expected
11771 outside the C locale.
11772
11773 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
11774 this is a GCC extension and is not portable to other compilers.

11777 Do not include <ctype.h>; no longer needed.

11779 warnings on OpenBSD 3.0).
11780

11782 it's not portable.

11785 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
11786
11787 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
11788 exit status as failure, not just exit status 1. Sun C exits
11789 with status 2 sometimes.
11790

14602 The ISO C++ standard is extremely clear about it: stderr is
14603 considered a macro, not a regular symbol (see table 94 `Header
14604 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).

14619 renaming.

14621 type mismatches, simplify.

14641 problems: because Flex includes the headers *before* us,
14642 _GNU_SOURCE is not defined by config.h, and therefore strndup was
14643 not visible.

14661 Don't use %option yylineno: it seems that then Flex imagines
14662 REJECT has been used, and therefore it won't reallocate its

14664 in warnings for `unused: yy_flex_realloc'.

14965
14966 * src/LR0.c (new_state): Recognize the final state by the fact it
14967 is reached by eoftoken.
14968 (insert_start_shifting_state, insert_eof_shifting_state)
14969 (insert_accepting_state, augment_automaton): Remove, since now
14970 these states are automatically computed from the initial state.
14971 (generate_states): Adjust.
14972 * src/print.c: When reporting a rule number to the user, substract
14973 1, so that the axiom rule is rule 0, and the first user rule is 1.
14974 * src/reduce.c: Likewise.
14975 * src/print_graph.c (print_core): For the time being, just as for
14976 the report, depend upon --trace-flags to dump the full set of
14977 items.
14978 * src/reader.c (readgram): Once the grammar read, insert the rule
14979 0: `$axiom: START-SYMBOL $'.
14980 * tests/set.at: Adjust: rule 0 is now displayed, and since the
14981 number of the states has changed (the final state is no longer
14982 necessarily the last), catch up.

14986 Try to make the use of the eoftoken valid. Given that its value
14987 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
14988 is used instead of > 0 where appropriate, (ii), depend upon nritems
14989 instead of the 0-sentinel.
14990
14991 * src/gram.h, src/gram.c (nritems): New.
14992 Expected to be duplication of nitems, but for the time being...
14993 * src/reader.c (packgram): Assert nritems and nitems are equal.
14994 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
14995 * src/closure.c (print_closure, print_fderives): Likewise.

15002 * src/main.c (main): If there are complains after grammar
15003 reductions, then output the report anyway if requested, then die.
15004 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
15005 * src/reader.c (eoftoken): New.
15006 (parse_token_decl): If the token being defined has value `0', it
15007 is the eoftoken.
15008 (packsymbols): No longer hack `tags' to insert `$' by hand.
15009 Be sure to preserve the value of the eoftoken.
15010 (reader): Make sure eoftoken is defined.
15011 Initialize nsyms to 0: now eoftoken is created just like the others.
15012 * src/print.c (print_grammar): Don't special case the eof token.
15013 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
15014 lie anyway, albeit pleasant.
15015 * tests/calc.at: Exercise error messages with eoftoken.
15016 Change the grammar so that empty input is invalid.
15017 Adjust expectations.
15018 When yyungeting, be sure to use a valid yylloc: use last_yylloc.

15104 members.
15105 (symbol_list_new): Adjust.
15106 (copy_action): action_line is the first line, not the last.
15107 (copy_guard): Just as for actions, store the `action' only, not
15108 the switch/case/break flesh.
15109 Don't parse the user action that might follow the guard, let...
15110 (readgram): do it, i.e., now, there can be an action after a
15111 guard.
15112 In other words the guard is just explicitly optional.
15113 (packgram): Adjust.
15114 * src/output.c (guards_output): New.
15115 (output_parser): Call it when needed.
15116 (output): Also free the guard and attrs obstacks.

15119 As a result, if one needs the former `.act' file, using an
15120 appropriate skeleton which requires actions and guards is now
15121 required.
15122 * src/main.c (main): Adjust.
15123 * tests/semantic.at: New.

15153 (conflicts_print, print_reductions): Use a state_t instead of an
15154 integer when referring to a state.
15155 As much as possible, depend upon nlookaheads, instead of the
15156 `lookaheadsp' member of the following state (since lookaheads of
15157 successive states are successive, the difference between state n + 1
15158 and n served as the number of lookaheads for state n).
15159 * src/lalr.c (add_lookback_edge): Likewise.

15356 Still making progress in separating Bison into (i) input, (ii)
15357 process, (iii) output: now we can directly output the parser file
15358 without using table_obstack at all.
15359
15360 * src/files.c, src/files.h (table_obstack): Bye bye.
15361 (parser_file_name): New.
15362 * src/files.c (compute_output_file_names): Compute it.
15363 * src/output.c (actions_output, output_parser)
15364 (output_master_parser): To a file instead of an obstack.

15372 * src/reader.c (symbol_list): Likewise.
15373 (copy_action): Save the actions within the rule.
15374 (packgram): Save them in rule_table.
15375 * src/output.c (actions_output): New.
15376 (output_parser): Use it on `%%actions'.
15377 (output_rule_data): Don't free rule_table.
15378 (output): Do it.
15379 (prepare): Don't save the `action' muscle.

15413 The computation of nullable is broken: it doesn't handle empty
15414 RHS's properly.

15416 * tests/torture.at (GNU AWK Grammar): New.
15417 * tests/sets.at (Nullable): New.
15418 * src/nullable.c (set_nullable): Instead of blindly looping over
15419 `ritems', loop over the rules, and then over their rhs's.
15420
15421 Work around Autotest bugs.
15422
15423 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
15424 frame, because Autotest understand lines starting with a `+' as
15425 traces from the shell. Then, they are not processed properly.
15426 Admittedly an Autotest bug, but we don't have time to wait for
15427 Autotest to catch up.

15429 frames.

15441 traces do: shifting the token EOF. Before EOF was treated as a
15442 nonterminal.
15443 * tests/regression.at: Adjust some tests.
15444 * src/print_graph.c (print_core): Complete the set of items via
15445 closure. The next-to-final and final states are still unsatisfying,
15446 but that's to be addressed elsewhere.
15447 No longer output the rule numbers, but do output the state number.
15448 A single loop for the shifts + gotos is enough, but picked a
15449 distinct color for each.
15450 (print_graph): Initialize and finalize closure.

15857 Because useless nonterminals are now kept alive (instead of being

15868 given state.

18253 The location tracking mechanism is precious for parse error
18254 messages. Nevertheless, it is enabled only when `@n' is used in
18255 the grammar, which is a different issue (you can use it in error
18256 message, but not in the grammar per se). Therefore, there should
18257 be another means to enable it.

18289 Test also `--verbose', `--defines' and `--name-prefix'. Testing
18290 the latter demonstrates a flaw in the handling of non debugging
18291 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
18292 was used in order to simplify:
18293
18294 #if YYDEBUG
18295 if (yydebug)
18296 {
18297 ...

18301 into
18302
18303 if (yydebug)
18304 {
18305 ...
18306 }
18307
18308 unfortunately this leads to a CPP conflict when
18309 `--name-prefix=foo' is used since it produces `#define yydebug
18310 foodebug'.

18360 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
18361 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
18362 difficult and introduced a lot of core dump. It turns out that
18363 Bison used an implementation of `xmalloc' based on `calloc', and
18364 at various places it does depend upon the initialization to 0. I
18365 have not tried to isolate the pertinent places, and all the former
18366 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,

19450 New function.
19451 (readgram): Use `#if 0' around code that accepted %command
19452 inside grammar rules: The documentation doesn't allow it,
19453 and it will fail since the %command processors scan for the next %.
19454 (parse_token_decl): Extended the %token
19455 declaration to allow a multi-character symbol as an alias.
19456 (parse_thong_decl): New function.
19457 (read_declarations): Added %thong declarations.
19458 (read_declarations): Handle NOOP to deal with allowing
19459 % declarations as another means to specify the flags.
19460 (readgram): Allow %prec prior to semantics embedded in a rule.
19461 (skip_to_char, read_declarations, copy_definition)
19462 (parse_token_decl, parse_start_decl, parse_type_decl)
19463 (parse_assoc_decl, parse_union_decl, parse_expect_decl)
19464 (get_type_name, copy_guard, copy_action, readgram)
19465 (get_type, packsymbols): Revised most error messages.
19466 Changed `fatal' to `warnxxx' to avoid aborting for error.
19467 Revised and use multiple warnxxx functions to avoid using VARARGS1.
19468 (read_declarations): Improve the error message for
19469 an invalid character. Do not abort.
19470 (read_declarations, copy_guard, copy_action): Use
19471 printable_version to avoid unprintable characters in printed output.
19472 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
19473 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
19474 Allow the type of a non-terminal can be given
19475 more than once, as long as all specifications give the same type.
19476
19477 * src/output.c:
19478 (output_headers, output_trailers, output, output_gram)
19479 (output_rule_data): Implement noparserflag variable.
19480 Implement toknumflag variable.
19481 (output): Call reader_output_yylsp to output LTYPESTR.
19482
19483 * src/main.c (main):
19484 If reader sees an error, don't process the grammar.
19485 (fatals): Updated to not use VARARGS1.
19486 (printable_version, int_to_string, warn, warni, warns, warnss)
19487 (warnsss): New error reporting functions. Avoid abort for error.
19488
19489 * src/lex.h:
19490 Added THONG and NOOP for alias processing.
19491 Added SETOPT for the new code that allows setting options with %flags.
19492
19493 * src/lex.c:
19494 Include getopt.h. Add some extern decls.
19495 (safegetc): New function to deal with EOF gracefully.
19496 (literalchar); new function to deal with reading \ escapes.
19497 (lex): Use literalchar.
19498 (lex): Implemented "..." tokens.
19499 (literalchar, lex, parse_percent_token): Made tokenbuffer
19500 always contain the token. This includes growing the token
19501 buffer while reading an integer.
19502 (parse_percent_token): Replaced if-else statement with percent_table.
19503 (parse_percent_token): Added % declarations as another
19504 way to specify the flags -n, -l, and -r. Also added hooks for
19505 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
19506 major changes to files.c.
19507 (lex) Retain in the incoming stream a character following
19508 an incorrect '/'.
19509 (skip_white_space, lex): Revised most error messages
19510 and changed fatal to warn to avoid aborting.
19511 (percent_table): Added %thong declarations.
19512
19513 * src/gram.h: Comment changes.
19514
19515 * src/files.c (openfiles, open_extra_files, done):
