176

187 issues in Bison, it would mean way too much duplicate effort to

AD		 2062001-01-19 Akim Demaille <akim@epita.fr>
207
208 * src/lex.h: Rename all the tokens:
209 s/\bENDFILE\b/tok_eof/g;
210 s/\bIDENTIFIER\b/tok_identifier/g;

225 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and

228 instead of returning a token.
229 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
230 * src/reader.c (read_declarations): Adjust.
231 * src/files.c (open_files): Don't call `compute_base_names', don't
232 compute `attrsfile' since they depend upon data which might be
233 *in* the input file now.
234 (output_files): Do it here.
235 * src/output.c (output_headers): Document the fact that this patch
236 introduces a guaranteed SEGV for semantic parsers.
237 * doc/bison.texinfo: Document them.

AD		 2632000-12-20 Akim Demaille <akim@epita.fr>
264

294 * src/files.c (strsuffix): New.
295 (stringappend): Be just like strcat but allocate.
296 (base_names): Eve out from open_files.

AD		 3382000-12-19 Akim Demaille <akim@epita.fr>
339
340 * src/files.c (open_files): Yipee! We no longer need all the code

424 argument `data' for consistency with the prototypes.
425 Qualify it `const'.
426 (obstack_copy, obstack_copy0): Rename the second argument as

599 The location tracking mechanism is precious for parse error
600 messages. Nevertheless, it is enabled only when `@n' is used in
601 the grammar, which is a different issue (you can use it in error
602 message, but not in the grammar per se). Therefore, there should
603 be another means to enable it.

635 Test also `--verbose', `--defines' and `--name-prefix'. Testing
636 the latter demonstrates a flaw in the handling of non debugging
637 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
638 was used in order to simplify:
639
640 #if YYDEBUG
641 if (yydebug)
642 {
643 ...
644 }
645 #endif
646
647 into
648
649 if (yydebug)
650 {
651 ...
652 }
653
654 unfortunately this leads to a CPP conflict when
655 `--name-prefix=foo' is used since it produces `#define yydebug
656 foodebug'.
657
658 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
659 (YYDPRINTF): New macro.
660 Spread its use.

706 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
707 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
708 difficult and introduced a lot of core dump. It turns out that
709 Bison used an implementation of `xmalloc' based on `calloc', and
710 at various places it does depend upon the initialization to 0. I
711 have not tried to isolate the pertinent places, and all the former
712 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
713 someone should address this issue.

1084 There is now a pseudo variable @$ (readble and writable), location
1085 of the lhs of the rule (by default ranging from the location of

1850 way to specify the flags -n, -l, and -r. Also added hooks for
