+
+ * 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.

+
+ 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
+ class typedefs.
+
+2005-06-22 Akim Demaille <akim@epita.fr>
+
+ * doc/bison.texinfo (C++ Language Interface): First stab.
+ (C++ Parsers): Remove.

+
+ * data/lalr1.cc (yylex_): Honor %lex-param.
+
+2005-06-22 Akim Demaille <akim@epita.fr>
+
+ Start a set of simple examples.
+ * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
+ * examples/calc++/calc++-driver.hh,
+ * examples/calc++/calc++-parser.yy,
+ * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
+ * examples/calc++/compile, examples/calc++/test: New.

+
+ * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
+ extern "C" {}. This fixes a problem reported by Paul Hilfinger,
+ which stems from the 2005-05-27 patch.
+
2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
* data/glr.c: Modify treatment of unused parameters to permit use
* tests/atlocal.at (GCC): New.
* tests/synclines.at (AT_TEST_SYNCLINE): New macro.
- (Prologue synch line, ,%union synch line, Postprologue synch line)
+ (Prologue synch line, %union synch line, Postprologue synch line)
(Action synch line, Epilogue synch line): New tests.
* src/reader.c (parse_union_decl): Define the muscle stype_line.
* data/bison.simple, data/bison.c++: Use it.
