Raw Normal View History

Import the FSF release of bison-1.25 onto the vendor branch. In case you're wondering, the gcc-2.7.2.1 import uses this to generate code. The size of the generated code is bigger than the entire bison release, making this a saving. The bison doc is pretty good apparently.

Sat May 11 15:11:15 1996 Richard Stallman <rms@delasyd.gnu.ai.mit.edu>

buffer while reading an integer.

(parse_percent_token): Added % declarations as another
way to specify the flags -n, -l, and -r. Also added hooks for

Eliminate upper case duplicate options.

Calls changed in LR0.c, conflicts.c, symtab.c, new.h.

* reader.c: Declare realloc.

* lex.c (lex, case '='): Update lineno when skipping a newline.
