+ similar wording in gettext's PACKAGING file.
+ * NEWS: Mention PACKAGING.
+ * Makefile.am (EXTRA_DIST): Add PACKAGING.
+
+2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS: Document recent i18n improvements.
+ * bootstrap: Get runtime translations into runtime-po.
+ Create runtime-po files automatically, if possible.
+ * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
+ * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
+ does not infringe on the user's name space.
+ (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
+ * doc/bison.texinfo (Internationalization): Revamp the English
+ and Texinfo syntax a bit, to try to make it clearer.
+ (Bison Options, Option Cross Key): Mention --print-localedir.
+ * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
+ YYENABLE_NLS. Quote a bit more.
+ * runtime-po/.cvsignore: New file.
+ * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.

+ * runtime-po/remove-potcdate.sin: Likewise.
+ * runtime-po/Makevars: Likewise.
+ * runtime-po/LINGUAS: Likewise.
+ * runtime-po/de.po: Likewise; we will rely on the translation project
+ to maintain this, so "bootstrap" should get it.
+ * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
+ its value.
+ * src/main.c (main): Bind the bison-runtime domain, too.
+
+2005-07-12 Bruno Haible <bruno@clisp.org>

+ * runtime-po: New directory.
+ * runtime-po/Makefile.in.in: New file, copied from po/, with modified
+ $(DOMAIN).pot-update rule, so that old messages are never dropped.

+
+ * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
+ for consistency with the rest of the code.
+ * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.

+
+2005-07-12 Akim Demaille <akim@epita.fr>

+
+2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
+
+ * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
+ and Pennello's paper.
+
+2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/yacc.c (yyparse): Undo previous patch. Instead,
+ set yylsp[0] and yyvsp[0] only if the initial action
+ sets yylloc and yylval, respectively.
+
+ * data/yacc.c (yyparse): In the initial action, set
+ yylsp[0] and yyvsp[0] rather than yylloc and yylval.
+ This avoids the use of undefined variables if the initial
+ action does not set yylloc and/or yylval.
+

+
+ * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
+ * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
+ Remove from CVS. These files are automatically generated.
+ * examples/extexi: Clarify that this file is now part of Bison,
+ not GNU M4, and that it works with any POSIX-compatible Awk.
+ * examples/calc++/Makefile.am (run_extexi): Remove; not used.
+ ($(calc_extracted)): Renamed from $(calc_sources_extracted),
+ so that we also get calc++-parser.yy. Geneate it.
+ Use $(AWK), not gawk, since any conforming Awk will do.
+ Put comment before action, since older 'make' can't handle comment
+ in action.
+ $(BUILT_SOURCES): List all built sources, not just some of them.
+ $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
+ $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
+ $($(calc_sources_generated)): Remove unnecessary test for existence
+ of target. (This had a shell syntax error anyway; a stray "x".)
+ (calc_extracted): List $(srcdir)/calc++-parser.yy, not
+ calc++-parser.yy.
+ * examples/.cvsignore, examples/calc++/.cvsignore: New files.
+
+ * bootstrap (gnulib_modules): Add gettext, now that it's no longer
+ implied by the other modules.
+
+2005-07-06 Akim Demaille <akim@epita.fr>
+
+ Bind examples/calc++ to the package.
+ * examples/calc++/Makefile: Remove, replaced by...
+ * examples/calc++/Makefile.am: ... this new file.
+ * examples/calc++/test: Remove input.
+ * examples/calc++/compile: Remove.
+ * examples/Makefile.am: New.
+ * configure.ac, Makefile.am: Adjust.
+ * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
+
+2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.c (yyFail): Drastically simplify; since the format argument
+ never had any % directives, we can simply pass it to yyerror.
+ (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
+ be modified later, as that is the usual style in glr.c.
+ Problems reported by Paul Hilfinger.
+
+ Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
+ and size overflow errors.
+ * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
+ in case the user prolog sets feature-test macros like _GNU_SOURCE.
+ (YYSIZEMAX): New macro.
+ (yystpcpy): New function, taken from yacc.c.
+ (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
+ (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
+ so that we don't have to maintain their signatures.
+ (yyFail): Check for buffer overflow, by using vsnprintf rather
+ than vsprintf. Allocate a bigger buffer if possible.
+ Report an error if buffer allocation fails.
+ (yyStackOverflow): New function.
+ (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
+ the initialization was successful. It might fail if storage was
+ exhausted.
+ (yyexpandGLRStack): Add more checks for storage allocation failure.
+ Use yyStackOverflow to report failures.
+ (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
+ (yysplitStack, yyprocessOneStack, yyparse, yypstack):
+ Don't assume stack number fits in int.
+ (yysplitStack): Check for storage allocation failure.
+ (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
+ can print diagnostics on storage allocation failure. All callers
+ changed.
+ (yyresolveValue): Use yybool for boolean.
+ (yyreportSyntaxError): Check for size-calculation overflow.
+ This code is taken from yacc.c.
+ (yyparse): Check for storage allocation errors when allocating
+ the initial stack.
+
+2005-07-05 Akim Demaille <akim@epita.fr>
+
+ Extract calc++ from the documentation.
+ * doc/bison.texinfo (Calc++): Add the extraction marks.
+ * examples/extexi: New, from the aborted GNU Programming 2E.
+ Separate the different paragraph of a file with empty lines.
+ * examples/Makefile: Use it to extract the whole calc++ example.
+
2005-06-24 Akim Demaille <akim@epita.fr>
* doc/bison.texinfo (C++ Parser Interface): Use defcv to define
projects / bison.git / blobdiff
