+2001-11-30 Akim Demaille <akim@epita.fr>
+
+ * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
+ if body instead of `;' to pacify GCC's warnings.
+
+2001-11-30 Akim Demaille <akim@epita.fr>
+
+ Instead of mapping the LHS of unused rules to -1, keep the LHS
+ valid, but flag the rules as invalid.
+
+ * src/gram.h (rule_t): `useful' is a new member.
+ * src/print.c (print_grammar): Adjust.

+ * src/bison.simple (YYSTACK_REALLOC): Remove.
+ (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
+ (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
+ New macros.
+ (union yyalloc): New type.
+ (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
+ an arbitrary restriction on hosts where size_t is wider than int.
+
+ (yyparse): Don't dump core if alloca or malloc fails; instead, report
+ a parser stack overflow. Allocate just one block of memory for all
+ three stacks, instead of allocating three blocks; this typically is
+ faster and reduces fragmentation.
+
+ Do not limit the number of items in the stack to a value that fits
+ in 'int', as this is an arbitrary limit on hosts with 64-bit
+ size_t and 32-bit int.
