+
+ * tests/cxx-type.at: Construct a tree, count the parents of shared
+ nodes, and free each node once and only once. Previously, the memory
+ for semantic values was leaked instead.

+2005-12-21 Joel E. Denny <address@hidden>
+
+ * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.
+ (yylval, yylloc): If pure, #define to yystackp->yyval and
+ yystackp->yyloc similar to yychar and yynerrs.
+ (yyparse): If pure, remove local yylval and yylloc. Add local
+ yystackp to accommodate pure definitions of yylval and yylloc.
+ (b4_lex_param, b4_lyyerror_args, b4_lpure_args): If pure, change
+ yylvalp and yyllocp to &yylval and &yylloc.
+ (nerrs, char, lval, lloc): If pure, add #define's for b4_prefix[]
+ namespace. Previously, nerrs and char were missing, but lval and lloc
+ weren't necessary.
+ (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Remove
+ yylvalp and yyllocp parameters since, if pure, these are now always
+ accessible through yystackp. If not pure, they are still accessible
+ globally.
+ * data/glr.c, data/yacc.c (YYLLOC_DEFAULT): Change `if (N)' to
+ `if (YYID (N))' to pacify lint.

+
+ YYACCEPT, YYERROR, and YYABORT, as user actions, should not
+ destroy the RHS symbols of a rule.
+ * data/yacc.c (yylen): Initialize to 0.
+ Keep its value to the number of items to possibly shift.
+ In particular, a regular successful parse that ends on YYFINAL by
+ a (internal) YYACCEPT must not have yylen != 0.
+ (yyerrorlab, yyreturn): Pop the RHS.
+ Reorder a bit to emphasize the `shifting' bits of code.
+ (YYPOPSTACK): Now accept a number of items to pop.
+ * data/lalr1.cc: Likewise.
+ * data/glr.c: Formatting changes.
+ Use goto instead of fall through.
+ * doc/bison.texinfo (Destructor Decl): Complete.

+
+ * Makefile.am: DJGPP specific files added to EXTRA_DIST.
+ * djgpp/Makefile.maint: Fix PACKAGE variable computation.
+ * djgpp/config.bat: Replace every occurence of the file name
+ scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
+ c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
+ * djgpp/config.sed: Replace every occurence of the file name
+ scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
+ c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
+ * djgpp/djunpack.bat: DJGPP specific file.
+ * djgpp/fnchange.lst: DJGPP specific file.
+ * djgpp/README.in: Add new information about how to unpack the bison
+ source on MSDOS and other systems which have 8.3 file name restrictions
+ using djunpack.bat and fnchange.lst.

+ (CVS_PREFIX): Adjust to yesterday's Savannah reorganization
+ when getting gnulib.
+
+2005-12-12 "Joel E. Denny" <jdenny@ces.clemson.edu>
+
+ * data/glr.c: Reorder typedef declarations for structs to match order
+ of struct declarations.
+ Rename yystack everywhere to yystackp except in yyparse where it's not
+ a pointer.
+ (yyglrShift): Change parameter YYSTYPE yysval to YYSTYPE* yyvalp for
+ consistency.
+ (yyis_table_ninf): Change 0 to YYID (0) to pacify lint.
+ (yyreportSyntaxError): Add /*ARGSUSED*/ to pacify lint.
+ (yyparse): Change while (yytrue) to while ( YYID (yytrue)) to pacify
+ lint.
+
+2005-12-09 Paul Eggert <eggert@cs.ucla.edu>
+
+ * tests/sets.at (Accept): Fix typos in regular expression used to
+ sed out the final state number.
+
+ Work around portability problem on Solaris 10: flex-generated
+ files include <stdio.h> before <config.h>, which messes up
+ because the latter defines __EXTENSIONS__. Address the problem
+ by creating two new little files that include <config.h> first,
+ then include the flex-generated files. Rewrite everyone else
+ to include <config.h> first, as well.
+ * lib/timevar.c: Always include "config.h".
+ * src/Makefile.am (bison_SOURCES): Replace scan-gram.l with
+ scan-gram-c.c, and scan-skel.l with scan-skel-c.c.
+ (EXTRA_bison_SOURCES): New macro.
+ * src/scan-gram-c.c, src/scan-skel-c.c: New files.
+ * src/system.h: Don't include config.h.

+ (current_lhs, current_lhs_location): Now static.
+ (current_assoc): Remove unused variable.
+
+ Cleanups so that Bison-generated parsers have less lint.
+ * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate):
+ Prepend /*ARGSUSED*/, for lint's sake.
+ * data/glr.c (YYUSE): Properly parenthesize, and use an alternate
+ definition if 'lint' is defined.
+ (YYID): New macro (or function, if lint).
+ All uses of /*CONSTCOND*/0 replaced by YYID(0).
+ * data/yacc.c: Likewise.
+ * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
+ (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
+ * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
+ is C++ only.
+ * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
+ * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
+ Use YYID(0) rather than 0, for lint.
+ (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.
+ (yysyntax_error): Rewrite to avoid lint warnings about parenthesization.

+
+2005-12-06 "Joel E. Denny" <jdenny@ces.clemson.edu>
+
+ * data/glr.c (yyprocessOneStack, yyparse): Synchronize the shift for

+ (yyparse): Iterate another stack in order to call user destructors.
+ * tests/glr-regression.at (No users destructors if stack 0 deleted):
+ New test case.
+ (Duplicated user destructor for lookahead): This test now is expected
+ to succeed.
+
2005-12-01 Paul Eggert <eggert@cs.ucla.edu>
+ * NEWS: Document the following change.
* data/yacc.c: Say "parser skeleton" rather than "file", since
it's no longer just a file.
* data/glr.c: Grant a special exception for C GLR parsers, that
