+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.

+
+2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
+
+ * data/glr.c: Modify treatment of unused parameters to permit use

+ the user's name space.
+ (alloca): Include <stdlib.h> to get it, if it's not built in.
+ (YYMALLOC, YYFREE): Define only if needed.
+ (malloc, free): Declare, but only if needed, as this infringes on

+ the previous change.
+
+ Various maintainer cleanups.
+ * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,

+ (yyoverflowlab): Don't call destructor.
+ (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
+ * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
+ since we no longer output the message "discarding lookahead token
+ end of input ()".
+
+2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
+
+ * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to

+ From Marcus Holland-Moritz.
+ * data/yacc.c (yyerrlab): Move the code that destroys the stack
+ from here....
+ (yyreturn): to here. That way, destructors are called properly
+ even if the stack overflows, or the user calls YYACCEPT or
+ YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
+ (yyoverflowlab): Destroy the lookahead.
+
+2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
+
+2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS: Bison-generated C parsers no longer quote literal strings

+ * src/output.c (prepare_symbols): Don't escape strings,
+ since users don't want to see C escapes.
+ * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
+ in diagnostics.

+
+ * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
+ the data size is known to be too small and we can't increase it.
+ This works around an HP-UX 11.00 glitch reported by Andrew Benham.
+
+2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/parse-gram.y: Include quotearg.h.
+ (string_as_id): Quote $1 before using it as a key, since the

+ (string_content): Don't strip quotes, since lexer no longer
+ quotes it for us.
+ * src/scan-gram.l: Include quotearg.h.
+ ("\""): Omit quote.
+ ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
+ a key, since the rest of the lexer doesn't quote it.

+ * tests/regression.at (Token definitions): Check for backslashes
+ in token strings.
+
+ * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
+ (YYSIZE_T): Define to unsigned long int when using an older compiler.
+ (yyparse): Revamp code to generate long syntax error message, to
+ make it easier to translate, and to avoid problems with arithmetic
+ overflow. Change "virtual memory" to "memory" in diagnostic, since
+ we don't know whether the memory is virtual.
+
+2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS: Bison-generated C parsers now use the _ macro to

+ * data/yacc.c (_) [!defined _]: New macro.
+ All English strings wrapped inside this macro.
+ * doc/bison.texinfo (Bison Parser): Document _.

+ includes translateable strings that parse-gram.y doesn't.
+
+2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/symtab.c (symbol_make_alias): Call symbol_type_set,
+ reverting the 2004-10-11 change to this function.
+ (symbol_check_alias_consistency): Don't call symbol_type_set
+ if the type name is already correct.
+ * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
+
+2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
+
+ * tests/regression.at (Token definitions): Don't use a token named
+ c, as that generates a "#define c ..." that runs afoul of buggy
+ stdlib.h that uses the identifier c as a member of struct
+ drand48_data. Problem reported by Horst Wente.
+
+2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
+
+ * bootstrap: Change translation URL from
+ http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to

+2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
+
+ * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options

+
+2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
+
+ * tests/glr-regression.at (glr-regr2a.y): Try to dump core

+ down what may be a spurious failure on MacOS.
+
+2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
+
+ Respond to problems reported by twlevo@xs4all.nl.

+
+2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/output.c (escaped_output): Renamed from
+ escaped_file_name_output, since we now use it for symbol tags as
+ well. All uses changed.
+ (symbol_destructors_output, symbol_printers_output):
+ Escape symbol tags too.
+ Problem reported by Matyas Forstner in
+ <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.

+
+2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
+
+ * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in

+
+2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
+

+
+2005-02-23 Paul Eggert <eggert@cs.ucla.edu>

+
+2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
+
+ * tests/glr-regression.at (Improper handling of embedded actions
+ and dollar(-N) in GLR parsers): Renamed from "Improper handling of
+ embedded actions and $-N in GLR parsers", work around an Autoconf bug
+ with dollar signs in test names.
+ * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
+ for a similar reason.
+
+2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
