+
+2004-02-25 Paul Eggert <eggert@twinsun.com>
+
+ * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from

+
+ * tests/local.at: Require Autoconf 2.59's Autotest.
+ * tests/testsuite.at: Don't include local.at, since we now assume
+ Autoconf 2.59 or later. Autoconf 2.59 had some problems with
+ including it.

+ multiple inclusion warnings.

+
+2003-10-04 Paul Eggert <eggert@twinsun.com>
+
+ * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
+ non-modifiable lvalue, instead of a modifiable one.
+ * doc/bison.texinfo (Actions): Document that $$ can
+ be assigned to. Do not claim that $$ and $N are
+ array element references: user code should not rely on this.
+
+2003-10-01 Paul Eggert <eggert@twinsun.com>
+
+ * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.
+ (grammar_declaration): Use it.

+
+2003-09-30 Paul Eggert <eggert@twinsun.com>

+
+2003-08-27 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify

+
+2003-08-26 Akim Demaille <akim@epita.fr>
+
+ * config/announce-gen (print_changelog_deltas): Neutralize "<#" as

+
+2003-08-25 Akim Demaille <akim@epita.fr>
+
+ * config/announce-gen, Makefile.cfg: New.

+ keeping local WGET and WGETFLAGS modifications from Paul Eggert.
+
+2003-08-25 Akim Demaille <akim@epita.fr>
+
+ When reducing initial empty rules, Bison parser read an initial
+ location that is not defined. This results in garbage, and that
+ affects Bison's own parser. Therefore we need (i) to extend Bison
+ to support a means to initialize this location, and (ii) to use
+ this CVS Bison to fix CVS Bison's parser.
+
+ * src/reader.h, reader.c (epilogue_augment): Remove, replace
+ with...
+ * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
+ * src/parse-gram.y: Adjust.
+ (%initial-action): New.
+ (%error-verbose): Since we require CVS Bison, there is no reason
+ not to use it.
+ * src/scan-gram.l: Adjust.
+ * src/Makefile.am (YACC): New, to make sure we use our own parser.
+ * data/yacc.c (yyparse): Use b4_initial_action.
+
+2003-08-25 Akim Demaille <akim@epita.fr>
+
+ * doc/bison.texinfo: Don't promote stdout for error messages.
+
+2003-08-25 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
+ From Alexandre Duret-Lutz.
+
+2003-08-25 Akim Demaille <akim@epita.fr>
+
+ Version 1.875c.
+
+2003-08-25 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
+ Use them.
+
+2003-08-25 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc (Parser::reduce_print_): New.
+ Use it.
+
+2003-08-25 Akim Demaille <akim@epita.fr>
+
+ Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
+ error recovery loops. This patch is based on
+ <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
+ Also, augment the similarity between lalr1.cc and yacc.c.
+ Note: the locations of error recovery rules are not correct yet.
+
+ * data/lalr1.cc: Comment changes to augment the similarity between
+ lalr1.cc and yacc.c.
+ (YYERROR): Goto to yyerrorlab, not yyerrlab1.
+ (yyerrlab1): Remove, but where it used to be (now the bottom part of
+ yyerrlab), when hitting EOF, pop the whole stack here instead of
+ merely falling thru the default error handling mechanism.
+ (yyerrorlab): New label, with the old contents of YYERROR,
+ plus the following change: pop the stack of rhs corresponding
+ to the production that invoked YYERROR. That is how Yacc
+ behaves (required by POSIX).
+ * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
+ fail.
+
+2003-08-25 Akim Demaille <akim@epita.fr>
+
+ Tune local.at so that people can "autom4te -l autotest calc.at -o
+ calc" for instance, to extract a sub test suite.
+
+ * tests/testsuite.at: Move the initialization, Autotest version
+ requirement, and AT_TESTED invocation into...
+ * tests/local.at: here.
+ * tests/testsuite.at: Include it for compatibility with Autoconf
+ 2.57.
+ * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
+ be ignore.
+
+2003-08-04 Paul Eggert <eggert@twinsun.com>
+
+ Rework code slightly to avoid gcc -Wtraditional warnings.
+ * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
+ The returned value is now stored in *YY0. All callers changed.
+ * src/output.c (merge_output): Adjust to the above change.
+
+2003-07-26 Paul Eggert <eggert@twinsun.com>
+
+ * data/glr.c (YYASSERT): New macro.
+ (yyfillin, yydoAction, yyglrReduce, yysplitStack,
+ yyresolveStates, yyprocessOneStack):
+ Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
+ Derived from a suggestion by Frank Heckenbach.
+
2003-07-25 Paul Eggert <eggert@twinsun.com>
* data/glr.c (yyglrReduce): Don't use C89 string concatenation,
