31 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
32 and "POSIX". Use more-modern syntax for URLs. Mention C++
33 and ask for Java. Don't hardwire OS version numbers. Add
34 copyright notice.
35 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
36 * src/conflicts.c (solved_conflicts_obstack): Now static.

41 page. Say "you can use it" not "you may use it" as on the web page;
42 we're describing capabilities not granting permission.

50 Modify yylex so that it uses its argument, rather than trying
51 to rely on ARGSUSED (which doesn't work for gcc with warnings).

64 (yyresolveValue): Invoke yyresolveLocations before reporting an
65 ambiguity.
66 * doc/bison.texinfo (Default Action for Locations): Note
67 YYLLOC_DEFAULT's usage for ambiguity locations.

74 (Leaked lookahead after nondeterministic parse syntax error): New test

82 * tests/glr-regression.at (Leaked semantic values when reporting
83 ambiguity): New test case.
84 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
85 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
86 now unnecessary yystackp parameter.
87 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
88 destructors can be called.

96 parser, and clean up related code a bit.

98 cuts parse): Rename to...
99 (Leaked semantic values if user action cuts parse): ... this. Add check
520181ab
JD
100 for leaked parent RHS values.
101 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
102 between an unresolved state (non-empty chain of semantic options) and
103 an incomplete one (signaled by an empty chain).
ae952af2 104 (yyresolveStates): Document the interface. Move all manipulation of a
520181ab
JD
105 successfully or unsuccessfully resolved yyGLRState to...
106 (yyresolveValue): ... here so that yyresolveValue always leaves a
107 yyGLRState with consistent data and thus is easier to understand.
108 Remove the yyvalp and yylocp parameters since they are always just
109 taken from the yys parameter. When reporting a discarded merged value
110 in debugging output, note that it is incompletely merged. Document the
111 interface.
112 (yyresolveAction): If resolving any of the RHS states fails, destroy
113 them all rather than leaking them. Thus, as long as user actions are
114 written to clean up the RHS correctly, yyresolveAction always cleans up
115 the RHS of a semantic option. Document the interface.

234 During deterministic GLR operation, user actions should be able to
235 influence the parse by changing yychar. To make this easier to fix and
236 to make glr.c easier to evolve in general, don't maintain yytoken in
237 parallel with yychar; just compute yytoken when needed.
238 * tests/glr-regression.at (Incorrect lookahead during deterministic
239 GLR): Check that setting yychar in a user action has the intended
240 effect.
241 * data/glr.c (yyGLRStack): Remove yytokenp member.
242 (yyclearin): Don't set *yytokenp.
243 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
244 yychar rather than *yytokenp to determine the current lookahead.
245 Compute yytoken locally when needed.
246 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
247 point to.

264 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
265 got from <http://bro-ids.org/download.html>. The bug is that
266 when two actions appeared in succession, the second one was
267 scanned before the first one was added to the grammar rule
268 as a midrule action. Bison then output the incorrect warning
269 "parse.y:905.17-906.36: warning: unused value: $3".
270 * src/parse-gram.y (BRACED_CODE, action): These are no longer
271 associated with a value.
272 (rhs): Don't invoke grammar_current_rule_action_append.
273 (action): Invoke it here instead.
274 * src/reader.c (grammar_midrule_action): Now extern.
275 (grammar_current_rule_action_append): Don't invoke
276 grammar_midrule_action; that is now the scanner's job.
277 * src/reader.h (last_string, last_braced_code_loc):
278 (grammar_midrule_action): New decls.
279 * src/scan-gram.l (last_string): Now extern, sigh.
280 (last_braced_code_loc): New extern variable.
281 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
282 rule already has an action.
283 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
284 * tests/input.at (AT_CHECK_UNUSED_VALUES):
285 Add some tests to check that the above changes fixed the bug.

291 not whether it is typed.

310 user can override the types.
311 (short): #undef, to work around a bug in Pike 7.0.
312 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
313 (union yyalloc.yyss): Use yytype_int16 rather than short.

1288 Use unlocked I/O for a minor performance improvement on hosts like
1289 GNU/Linux and Solaris that support unlocked I/O. The basic idea

PE
1622 * data/glr.c (YYCHK1): Do not assume YYE is in range.
1623 This avoids a diagnostic from gcc -Wswitch-enum.

PE
1626 * doc/bison.texinfo: Don't use "filename", as per GNU coding
1627 standards. Use "file name" or "file" or "name", depending on
1628 the context.
1629 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
1630 not to hack/foo.tab.c.
1631 (Calc++ Top Level): 2nd arg of main is not const.

dd5f2af2
PE
1700 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
1701 in yydestruct diagnostic, since it might not be an error.
1702 Problem reported by Joel Denny near end of

1708 * src/files.c: Remove obsolete FIXME comment.
1709
1710 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
1711 with the other templates, and to fix bogus run-on messages such
1712 as the one reported at the end of
1713 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
1714 All callers changed to avoid the newline.
1715 (yyprocessOneStack): Output two lines rather than one, to accommodate
1716 the above change. This changes the debug output format slightly.

PE
1736 * tests/regression.at (Token definitions): Don't rely on
1737 AT_PARSER_CHECK for data that contains backslashes. It currently
1738 uses 'echo', and 'echo' isn't portable if its argument contains
1739 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
1740 that the byte '\0xff' is not printable in the C locale; it is,
1741 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
1742 not printable, so use '\0x81' to test.
1743

PE
1744 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
1745 version of GCC, since the macro is used with non-GCC compilers.

1747 Fix core dump reported by Pablo De Napoli in

1751 it as an index.
1752
04098407
PE
1753 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
1754 the user's name space. All uses changed to __attribute__
1755 ((__unused__)).
1756 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
1757 Add __attribute__ ((__noreturn__)).
1758
1759 * etc/clcommit: Remove. We weren't using it, and it failed
1760 "make maintainer-distcheck".
1761 * Makefile.maint: Merge from coreutils.
1762 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
1763 (syntax-check-rules): Change list of rules as described below.

1773 (makefile_path_separator_check, copyright-check):
1774 Use grep -n, to make it easier to find violations.
1775 Use CVS_LIST and CVS_LIST_EXCEPT.
1776 (header_regexp, h_re): Remove.
1777 (dd_c): New macro.
1778 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
1779 (my-distcheck): Use more-modern GCC flags.
1780 (signatures, %.asc): Remove.
1781 (rel-files, announcement): Remove signatures.
1782 Restore old updating code, even though we don't use it, so
1783 that we're the same as coreutils.
1784 (alpha, beta, major): Depend on news-date-check.
1785 Make the upload commands.
1786

1796 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
1797 we comment out the Autoconf version number.
1798 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
1799 it's error-prone and "make maintainer-distcheck" rejects it.
1800
1801 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
1802 Indent calls to "error" to pacify "make maintainer-distcheck",
1803 when the calls are not intended to be translated.
1804 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
1805
1806 * src/Makefile.am (DEFS): Use +=, to pacify
1807 "make maintainer-distcheck".
1808 (bison_SOURCES): Add scan-skel.h.

1819 * src/main.c (main): Cast bindtextdomain and textdomain calls to
1820 void, to avoid warning when NLS is disabled.
1821 * src/output.c: Include scan-skel.h.
1822 (scan_skel): Remove decl, since scan-skel.h does this.
1823 (output_skeleton):
1824 Indent calls to "error" to pacify "make maintainer-distcheck".
1825 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
1826 * src/reader.h (gram_end, gram_lineno): New decls to pacify
1827 "make maintainer-distcheck".
1828 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
1829 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
1830 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):

1833 * src/uniqstr.c (uniqstr_assert):
1834 Indent calls to "error" to pacify "make maintainer-distcheck".
1835
1836 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
1837 not @VAR@.
1838
1839 * tests/torture.at: Revamp to avoid misuse of atoi that
1840 "make maintainer-distcheck" complained about.
1841
1842 * examples/extexi (message): Don't print a message more than once,
1843 and omit line-number decoration that makes Emacs compile think
1844 that informative messages are worth worrying about.
1845
18462005-07-22 Paul Eggert <eggert@cs.ucla.edu>

1848 * configure.ac: Update version number.
1849
1850 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
1851 accidentally.
1852 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
1853 autogenerated by the maintainer.
1854 * examples/calc++/.cvsignore: Add *.yy.
1855
1856 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.

1858 * lib/bitsetv.c (bitsetv_alloc): Likewise.
1859
1860 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
1861
1862 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
1863 from maintainer-distcheck about casting the argument of 'free'.
1864
1865 * NEWS: Mention recent yytname changes.
1866 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
1867
1868 * bootstrap: For translations that have not yet been upgraded to
1869 the new runtime-po domain, prime the pump by extracting the
1870 relevant strings from the obsolete translations. This code can be
1871 removed once the bison-runtime domain has been translated by each
1872 team.
1873
1874 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
1875 now that token names are already quoted.
1876
1877 Fix problem reported by Anthony Heading.
1878 * data/glr.c (YYTOKEN_TABLE): New macro.
1879 (yytname): Define if YYTOKEN_TABLE.

1888 again if the first call fails.
1889
1890 * data/glr.c (yytnamerr): New function.
1891 (yyreportSyntaxError): Use it to dequote most string literals.
1892 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
1893 with other skeletons. All uses changed.
1894 (yytnameerr_): New function.
1895 (yyreport_syntax_error): Use it to dequote most string literals.
1896 * data/yacc.c (yytnamerr): New function.

1898 * doc/bison.texinfo (Decl Summary, Calling Convention):
1899 Clarify quoting convention of yytname.
1900 * src/output.c (prepare_symbols): Quote all names. This undoes
1901 the 2005-04-17 change, which is now accomplished (mostly) via
1902 changes in the parsers as described above.
1903 * tests/regression.at (Token definitions, Web2c Actions):
1904 Undo most 2005-04-17 change here, too.
1905
19062005-07-20 Paul Eggert <eggert@cs.ucla.edu>
1907
1908 Fix more problems reported by twlevo@xs4all.nl.
1909 * tests/cxx-type.at: Don't pipe output of ./types through sed to
1910 remove trailing spaces. This loses the exit status of ./types,
1911 and isn't needed since ./types shouldn't be emitting trailing
1912 spaces.
1913 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
1914 as the stack isn't valid in that case.
1915
1916 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
1917 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
1918 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
1919 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
1920 is used.
1921 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
1922 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):

1924 Likewise.
1925
1926 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
1927 overly-picky compilers that reject 'char *foo = "bar";'.
1928
1929 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
1930 to FILE * parameter, not to stderr. This fixes a typo introduced
1931 in the 2005-07-12 change.
1932
1933 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
1934 warnings from GCC 4.
1935
1936 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):

1945 Destructor cleanups and regularization among the three skeletons.
1946 * NEWS: Document the behavior changes.
1947 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
1948 stack before failing, as the cleanup code will do it for us now.
1949 * data/lalr1.cc (yyerrlab): Likewise.
1950 * data/glr.c (yyparse): Pop everything off the stack before
1951 freeing it, so that destructors get called properly.
1952 * data/lalr1.cc (yyreturn): Likewise.
1953 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
1954 This is more consistent.
1955 * doc/bison.texinfo (Destructor Decl): Mention more reasons
1956 why destructors might be called. 1.875 -> 2.1.
1957 (Destructor Decl, Decl Summary, Table of Symbols):
1958 Some English-language cleanups for %destructor.
1959 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

1968 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
1969 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
1970 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
1971 Rename yyoverflowab to yyexhaustedlab.
1972 When memory exhaustion occurs during syntax-error reporting,
1973 report it separately rather than in a single diagnostic; this
1974 eases translation.
1975 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
1976 (Memory Exhausted): Renamed from Parser Stack Overflow.
1977 Revamp wording slightly to prefer "memory exhaustion".
1978 * tests/actions.at: "parser stack overflow" -> "memory exhausted".

1982 Add i18n support to the GLR skeleton. Partially fix the C++
1983 skeleton; a C++ expert needs to finish this. Remove debugging
1984 msgids; there's little point to having them translated, since they
1985 can be understood only by someone who can read the
1986 (English-language) source code.
1987
1988 Generate runtime-po/bison-runtime.pot automatically, so that we
1989 don't have to worry about garbage getting in that file. We'll
1990 make sure after the next official release that old msgids don't
1991 get lost. See
1992 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
1993
1994 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
1995 Now auto-generated.
1996 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
1997 Fix typos in explanations of the runtime file.
1998 * bootstrap: Change gettext keyword from YYI18N to YY_.
1999 Use standard Makefile.in.in in runtime-po, since we'll arrange
2000 for backward-compatible bison-runtime.po files in a different way.
2001 * data/glr.c (YY_): New macro, from yacc.c.
2002 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
2003 Translate messages intended for users.
2004 (yyreportSyntaxError): Change "virtual memory" to "memory" to match

2815 Remove uses of 'short int' and 'unsigned short int'. This raises
2816 some arbitrary limits. It uses more memory but nowadays that's
2817 not much of an issue.

2819 This change does not affect the generated parsers; that's a different
2820 task, as some users will want to conserve memory there.

2822 Ideally we should use size_t to represent all object counts, and

3223 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
3224 whether the reducion was empty or not. This leaves room to
3225 improve the use of YYLLOC_DEFAULT in such a case.
3226 lalr1.cc is still experimental, so changing this is acceptable.
3227 And finally, there are probably not many users who changed the
3228 handling of locations in GLR, so changing is admissible too.
3229
3230 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
3231 empty reduction, set @$ to an empty location ending the previously

3331 This allows to replace code relying on the implementation of

3333 * data/yacc.c (yylerrsp): Replace with...
3334 (yyerror_range): this.

3365 output the location within the %printer.

3373 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
3374 Bison directive from the Bison file to the invocation of this
3375 macro, so that these directives are passed to
3376 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
3377 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
3378 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
3379 the extra Bison directives instead of the whole series.
3380 Change the grammar so that there are recoverable errors, and
3381 unrecoverable errors. Now we can have the parser give up before
3382 consuming the whole input. As a result we now can observe that
3383 the lookahead is freed when needed.
3384 Change the parser source to parse argv[1] instead of a hard coded
3385 string.
3386 Simplify yylex, and give a value and location to EOF.
3387 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
3388 passed directives already coded in the file.
3389 Add some tests to check the location of "error".
3390 For some tests, the C++ parser is correct, and not yacc.c.
3391 For other tests, they provide different, but unsatisfying, values,
3392 so keep the C++ value so that at least one parser is "correct"
3393 according to the test suite.
3394 (Actions after errors): Remove, this is subsumed by the
3395 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

3559 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
3560 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

3573 Spent a few hours checking out which prerequisite versions the
3574 current sources actually require. I went all the way back to
3575 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
3576 a seemingly endless set of combinations of versions more recent
3577 than that. The bottom line is that the current sources require
3578 fairly recent versions of the build tools, and it'll be some work
3579 to change this.
3580 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
3581 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
3582 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
3583 Add comments explaining why those particular versions are
3584 currently needed.

3619 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
3620 autopoint's.

4095 When reducing initial empty rules, Bison parser read an initial
4096 location that is not defined. This results in garbage, and that

4394 The problem was that GLR parsers did not conform to the C standard,
4395 because actions like { $1 = $2 + $3; } expanded to expressions
4396 that invoked YYFILL in separate subexpressions, and YYFILL assigned
4397 to a local variable. The C standard says that expressions
4398 like (var = f ()) + (var = f ()) have undefined behavior.
4399 Another problem was that GCC sometimes issues warnings that
4400 yyfill and its parameters are unused.
4401
4402 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
4403 as possibly unused.
4404 (yyfill): New function.
4405 (YYFILL): Use it.
4406 (yyuserAction): Change type of yynormal to bool, so that it matches
4407 the new yyfill signature. Mark it as possibly unused.

4410 Follow up on a bug I reported in February, where a Bison-generated
4411 parser can loop. Provide a test case and a fix for yacc.c. I
4412 don't have a fix for lalr1.cc or for glr.c, unfortunately.
4413 The original bug report is in:

4415
4416 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
4417 macro's size was becoming unwieldy.
4418 (yyerrlab): Do not discard an empty lookahead symbol, as this
4419 might destroy garbage.
4420 (yyerrorlab): New label, with the old contents of YYERROR,
4421 plus the following change: pop the stack of rhs corresponding
4422 to the production that invoked YYERROR. That is how Yacc
4423 behaves, and POSIX requires this behavior.
4424 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
4425 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
4426 Define 'alarm' to do nothing if unistd.h is not available.
4427 Add a new rule "exp: '-' error;" to test the above change to
4428 data/yacc.c. Use 'alarm' to abort any test taking longer than
4429 10 seconds, as it's probably looping.
4430 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
4431 Also, the new yacc.c generates two fewer diagnostics for an
4432 existing test.

5060 we don't need to worry about yyerrlab1 being reported as an
5061 "unused label" by non-GCC C compilers. The downside is that if
5062 locations are used then a couple of statements are duplicated each
5063 time YYERROR is invoked, but the upside is that the warnings
5064 should vanish.

5082 popped). This means that the initial elements will not be freed
5083 explicitly, as is the case in yacc.c; it is not a problem, as
5084 these elements have fake values.

5193 * doc/bison.texinfo (Understanding): Use Yacc style for

5195 * src/conflicts.c (conflict_report):
5196 Renamed from conflict_report_yacc, removing the old
5197 'conflict_report'. Translate the entire conflict report at once,
5198 so that we don't assume that "," has the same interpretation in
5199 all languages.
5200 (conflicts_output): Use Yacc-style conflict report for each state,
5201 instead of our more-complicated style.
5202 (conflicts_print): Use Yacc-style conflict report, except print
5203 the input file name when not emulating Yacc.
5204 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted

5221 * data/yacc.c (yyparse): New local var yylerrsp, to record the
5222 top of the location stack's error locations.
5223 (yyerrlab): Set it. When discarding a token, push its location
5224 onto yylerrsp so that we don't lose track of the error's end.
5225 (yyerrlab1): Now is only the target of YYERROR, so that we can
5226 properly record the location of the action that failed. For GCC
5227 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
5228 GCC warning about yyerrlab1 being unused if YYERROR is unused.
5229 (yyerrlab2): New label, which yyerrlab now falls through to.
5230 Compute the error's location by applying YYLLOC_DEFAULT to
5231 the locations of all the symbols that went into the error.
5232 * doc/bison.texinfo (Location Default Action): Mention that
5233 YYLLOC_DEFAULT is also invoked for syntax errors.
5234 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

5293 If the user does not define YYSTYPE as a macro, Bison now declares it
5294 using typedef instead of defining it as a macro. POSIX requires this.
5295 For consistency, YYLTYPE is also declared instead of defined.
5296
5297 %union directives can now have a tag before the `{', e.g., the
5298 directive `%union foo {...}' now generates the C code
5299 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
5300 The default union tag is `YYSTYPE', for compatibility with Solaris 9
5301 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
5302 instead of `yyltype'.
5303
5304 `yystype' and `yyltype' are now obsolescent macros instead of being
5305 typedefs or tags; they are no longer documented and will be

5319 Solaris 9 yacc.

5338 has (or usually has) an immediately-following braced code.

5340 to return when scanning braced code.

6299 Use new @ escapes consistently. Represent brackets with @{ and @}
6300 rather than @<:@ and @:>@, since this works a bit better with dumb
6301 editors like vi. Represent @ with @@, since @ is now consistently
6302 an escape. Use @oline@ and @ofile@ rather than __oline__ and
6303 __ofile__, to avoid unexpected expansions. Similarly, use @output
6304 rather than #output.
6305
6306 * data/c.m4 (b4_copyright): Omit file name from comment, since
6307 the file name could contain "*/".
6308 (b4_synclines_flag): Don't quote the 2nd argument; it should already
6309 be quoted. All uses changed.

6323 mishandled funny characters in file names, and anyway it isn't
6324 needed any more.
6325 * data/yacc.c: Likewise.

6347 escapes other than \\ and \'; this simplifies the code.

6349 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
6350 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
6351 Use new escapes @{ and @} for [ and ].
6352
6353 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
6354 them with auto vars.
6355 Switch to new escape scheme, where @ is the escape character uniformly.
6356 Abort if a stray escape character is found. Avoid unbounded input
6357 buffer when parsing non-escaped text.
6358

6368 table.
6369 (yygetLRActions, yyrecoverParseError): Use them.

6371 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
6372 counted in the token inserted at end of file. Now takes
6373 location_t *, not location_t, so that the location can be
6374 adjusted. All uses changed.

6380 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
6381 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
6382 abort ();'. This reduces the runtime of the "Many lookaheads"

6394
6395 Remove nounput option. At an unexpected end of file, we now unput

6605 in symbols, long literals, and funny escapes in strings.

7088 Let nondeterministic skeletons be usable with deterministic
7089 tables.
7090
7091 With the patch, GAWK compiled by GCC without -O2 passes its test
7092 suite using a GLR parser driven by LALR tables. It fails with -O2
7093 because `struct stat' gives two different answers on my machine:
7094 88 (definition of an auto var) and later 96 (memset on this var).
7095 Hence the stack is badly corrumpted. The headers inclusion is to
7096 blame: if I move the awk.h inclusion before GLR's system header
7097 inclusion, the two struct stat have the same size.

7151 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,

7627 name locals "index", as it generates unnecessary warnings on some

7669 to minimize the number of warnings from xgettext.
7670 (handle_action_dollar, handle_action_at): Don't use isdigit,
7671 as it mishandles negative chars and it may not work as expected
7672 outside the C locale.
7673
7674 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
7675 this is a GCC extension and is not portable to other compilers.

7678 Do not include <ctype.h>; no longer needed.
7679 Do not include <malloc.h>; no longer needed (and generates
7680 warnings on OpenBSD 3.0).
7681

7683 it's not portable.
7684
7685 * tests/regression.at: Do not use 'cc -c input.c -o input';
7686 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
7687
7688 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
7689 exit status as failure, not just exit status 1. Sun C exits
7690 with status 2 sometimes.

11758 Because useless nonterminals are now kept alive (instead of being
11759 `destroyed'), we now sometimes examine them, and store information
11760 related to them. Hence we need to know their number, and adjust
11761 memory allocations.
11762
11763 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
11764 static.
11765 * src/LR0.c (allocate_itemsets): The memory allocated to
11766 `symbol_count' was used for two different purpose: once to count
11767 the number of occurrences of each symbol, and later reassigned to
11768 `shift_symbol', containing the symbol that can be shifted from a
11769 given state.
11770 Deobfuscate, i.e., allocate, use and free `symbol_count' here
11771 only, and...
11772 (new_itemsets): Allocate `shift_symbol' here.
11773 (allocate_itemsets): symbol_count includes useless nonterminals.
11774 Make room for them.
11775 (free_storage): Use `free', not `XFREE', for pointers that cannot
11776 be null.

11918
11919 (yyparse): Don't dump core if alloca or malloc fails; instead, report
11920 a parser stack overflow. Allocate just one block of memory for all
11921 three stacks, instead of allocating three blocks; this typically is
11922 faster and reduces fragmentation.

11924 Do not limit the number of items in the stack to a value that fits

14154 The location tracking mechanism is precious for parse error
14155 messages. Nevertheless, it is enabled only when `@n' is used in
14156 the grammar, which is a different issue (you can use it in error
14157 message, but not in the grammar per se). Therefore, there should
14158 be another means to enable it.
14159

14190 Test also `--verbose', `--defines' and `--name-prefix'. Testing
14191 the latter demonstrates a flaw in the handling of non debugging
14192 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
14193 was used in order to simplify:
14194
14195 #if YYDEBUG
14196 if (yydebug)
14197 {
14198 ...
14199 }
14200 #endif
14201
14202 into
14203
14204 if (yydebug)
14205 {
14206 ...
14207 }
14208
14209 unfortunately this leads to a CPP conflict when
14210 `--name-prefix=foo' is used since it produces `#define yydebug
14211 foodebug'.
14212
14213 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
14214 (YYDPRINTF): New macro.

14261 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
14262 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
14263 difficult and introduced a lot of core dump. It turns out that
14264 Bison used an implementation of `xmalloc' based on `calloc', and
14265 at various places it does depend upon the initialization to 0. I
14266 have not tried to isolate the pertinent places, and all the former
14267 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
14268 someone should address this issue.
