12 | New. | |
13 | * tests/actions.at, tests/calc.at, tests/conflicts.at, | |
14 | * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at, | |
15 | * tests/regression.at, tests/torture.at: Use them for all the | |
16 | grammars that are to be compiled. | |
17 | * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as... | |
18 | * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this. | |

22 | ||
23 | * doc/bison.texinfo: Various formatting changes (alignments in | |
24 | samples, additional @group/@end group, GCS in samples. | |
25 | Use @deffn instead of simple @table to define the directives, | |
26 | macros, variables etc. | |

33 | * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c |
34 | -o c"; the HP-UX 11i C compiler chatters during compilation. | |
35 | Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c". | |
36 | * tests/headers.at (export YYLTYPE): Likewise. | |
37 | ||
38 | * tests/input.at (Torturing the Scanner): Remove lines containing | |
39 | solitary backslashes, as they tickle a bug in the HP-UX 11i C | |
40 | compiler. | |
41 | ||
9a86cdb9 PE |
42 | * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid // |
43 | comments, since they're not portable. Use GNU coding style. | |

47 | * data/yacc.c: Leave bigger chunks of quoted text. | |
48 | (YYDSYMPRINTF): New. | |
49 | Use it to report symbol activities. | |
50 | * data/glr.c (YYDSYMPRINTF): New. | |

54 | ||
55 | Version 1.75b. | |
56 | ||
57 | * data/glr.c (yydoAction): Return YYRESULTTAG, not int. | |
58 | (yyglrReduce): Return yyok, not 0. | |
59 | This should avoid the enumerated-type warnings reported | |
60 | by Nelson H.F. Beebe in | |
61 | <http://mail.gnu.org/pipermail/bug-bison/2002-November/001872.html>. | |
62 | ||
63 | * lib/bbitset.h (BITSET_INLINE): Remove. | |
64 | * lib/bitset.h [! BITSET_INLINE]: Remove. | |
65 | (bitset_set, bitset_reset, bitset_test): Rename local vars | |
66 | to avoid shadowing warnings by GCC. | |
67 | ||
68 | * data/glr.c (inline): Remove #define. It's the user's | |
69 | responsibility to #define it away, just like 'const'. | |
70 | This fixes one of the bugs reported by Nelson H.F. Beebe in | |
71 | <http://mail.gnu.org/pipermail/bug-bison/2002-November/001873.html>. | |
18b519c0 | 72 | |
87f721cc PE |
73 | * Makefile.maint (po-check): Scan .l and .y files instead of the |
74 | .c and the .h files that they generate. This fixes the bug | |
75 | reported by Tim Van Holder in: | |
76 | <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html> | |
77 | Look for N_ as well as for _. Try to avoid matching #define for | |
78 | N_ and _. | |
79 | * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c, | |
80 | src/system.h. Add src/parse-gram.y, src/scan-gram.l. | |
81 | * src/scan-gram.l: Revamp regular expressions so that " and ' | |
82 | do not confuse xgettext. | |
83 | ||
84 | * src/struniq.h (struniq_new): Do not declare the return type | |
85 | to be 'const'; this violates the C standard. | |
86 | * src/struniq.c (struniq_new): Likewise. | |

132 | (b4_yydestruct_generate): Likewise. | |
133 | * tests/cations.at (Printers and Destructors): Use Bison directives | |

138 | ||
139 | * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New. | |
140 | * data/yacc.c: Rename yychar1 as yytoken, as in glr.c. | |
141 | Don't work on yychar (i.e., do set it to YYEMPTY, don't match | |
142 | it against YYEMPTY and so forth), work on yytoken (i.e., set | |
143 | it to YYEMPTY etc.). | |
144 | (yydestruct): Replace with a b4_yydestruct_generate invocation. | |
145 | (b4_symbol_actions): Remove. | |
146 | * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands | |
147 | for 0, end-of-input. | |

155 | * src/tables.c (tables_generate): Use free for pointers that | |
156 | cannot be NULL, not XFREE. | |

158 | * src/state.c (state_new): Likewise. | |

167 | Restore. | |
168 | * src/scan-gram.l (last_string): Is global to the file, not to | |
169 | yylex. | |
170 | * src/parse-gram.y (input): Don't append the epilogue here, | |
171 | (epilogue.opt): do it here, and free the scanner's obstack. | |
172 | * src/reader.c (epilogue_set): Rename as... | |

186 | * src/struniq.h, src/struniq.c (struniq_t): Is const. | |
187 | (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New. | |
188 | ||
189 | Use struniq for symbols. | |
190 | ||
191 | * src/symtab.h (symbol_t): The tag member is a struniq. | |
192 | (symbol_type_set): Adjust. | |
193 | * src/symtab.c (symbol_new): Takes a struniq. | |
194 | (symbol_free): Don't free the tag member. | |
195 | (hash_compare_symbol_t, hash_symbol_t): Rename as... | |
196 | (hash_compare_symbol, hash_symbol): these. | |
197 | Use the fact that tags as struniqs. | |
198 | (symbol_get): Use struniq_new. | |
199 | * src/symlist.h, src/symlist.c (symbol_list_n_type_name_get): | |
200 | Returns a strniq. | |
201 | * src/reader.h (merger_list, grammar_currentmerge_set): The name | |
202 | and type members are struniqs. | |
203 | * src/reader.c (get_merge_function) | |
204 | (grammar_current_rule_merge_set): Adjust. | |

214 | * src/complain.h, src/complain.c: Likewise. | |
215 | * src/main.c (main): Call struniqs_new early enough to use it for | |
216 | file names. | |
217 | Don't free the input file name. | |

219 | 2002-11-12 Akim Demaille <akim@epita.fr> |
220 | ||
221 | * src/symtab.c (symbol_free): Remove dead deactivated code: | |

233 | ||
234 | Revamp to fix many (but not all) of the C- and M4-related quoting | |
235 | problems. Among other things, this fixes the Bison bug reported | |
236 | by Jan Hubicka when processing the Bash grammar; see: | |
237 | <http://mail.gnu.org/pipermail/bison-patches/2002-November/001329.html> | |
238 | ||
239 | Use new @ escapes consistently. Represent brackets with @{ and @} | |
240 | rather than @<:@ and @:>@, since this works a bit better with dumb | |
241 | editors like vi. Represent @ with @@, since @ is now consistently | |
242 | an escape. Use @oline@ and @ofile@ rather than __oline__ and | |
243 | __ofile__, to avoid unexpected expansions. Similarly, use @output | |
244 | rather than #output. | |
245 | ||
246 | * data/c.m4 (b4_copyright): Omit file name from comment, since | |
247 | the file name could contain "*/". | |
248 | (b4_synclines_flag): Don't quote the 2nd argument; it should already | |
249 | be quoted. All uses changed. | |
250 | ||
251 | * data/glr.c: Use new @ escapes consistently. | |
252 | (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name, | |
253 | b4_output_header_suffix, b4_output_header_name, b4_header_guard): | |
254 | Remove, since they couldn't handle arbitrary characters in file | |
255 | names. | |
256 | * data/lalr1.cc: Likewise. | |
257 | * data/yacc.c: Likewise. | |
258 | ||
259 | * src/files.c (output_infix): Remove; all uses removed. | |
260 | * src/files.h: Likewise. | |
261 | ||
262 | * data/glr.c: Remove use of "#ifdef b4_header_guard", since it | |
263 | mishandled funny characters in file names, and anyway it isn't | |
264 | needed any more. | |
265 | * data/yacc.c: Likewise. | |
266 | * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard. | |
267 | ||
268 | * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would. | |
269 | * data/yacc.c: Likewise. | |
270 | ||
271 | * src/muscle_tab.c: Include quotearg.h, since we need to quote C | |
272 | strings now. | |
273 | (muscle_init): Quote filename as a C string. | |
274 | * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused. | |
275 | (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros. | |
276 | * src/output.c (escaped_file_name_output): New function. | |
277 | (prepare_symbols): Quote tokens for M4. | |
278 | (prepare): Don't insert output_infix, output_prefix, | |
279 | output_parser_name, output_header_name; this is now down by scan-skel. | |
280 | Insert skeleton as a C string. | |
281 | ||
282 | * src/output.c (user_actions_output, symbol_destructors_output, | |
283 | symbol_printers_output): Quote filenames for C and M4. | |
284 | * src/reader.c (prologue_augment, epilogue_set): Likewise. | |
285 | ||
286 | * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash | |
287 | escapes other than \\ and \'; this simplifies the code. | |
288 | (<SC_STRING>): Likewise, for \\ and \". | |
289 | (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE, | |
290 | SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too. | |
291 | Use new escapes @{ and @} for [ and ]. | |
292 | ||
293 | * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing | |
294 | them with auto vars. | |
295 | Switch to new escape scheme, where @ is the escape character uniformly. | |
296 | Abort if a stray escape character is found. Avoid unbounded input | |
297 | buffer when parsing non-escaped text. | |
298 | ||
299 | * tests/input.at (Torturing the Scanner): Add tests that @oline@, | |
300 | __oline__, #output, $@, and @{ do not have unintended meanings. | |
301 | ||
acea4f3b PE |
302 | 2002-11-09 Paul Eggert <eggert@twinsun.com> |
303 | ||
304 | Fix the test failure due to GCC warnings described in | |
305 | <http://mail.gnu.org/pipermail/bug-bison/2002-November/001815.html>. | |
306 | * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which | |
307 | evaluate to 0 if it's impossible for NINF to be in the respective | |
308 | table. | |
309 | (yygetLRActions, yyrecoverParseError): Use them. | |
310 | ||
311 | * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were | |
312 | counted in the token inserted at end of file. Now takes | |
313 | location_t *, not location_t, so that the location can be | |
314 | adjusted. All uses changed. | |
315 | ||
316 | * tests/regression.at (Invalid inputs): Adjust wording in | |
317 | diagnostic to match the new behavior. | |
318 | ||
319 | * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR, | |
320 | AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR, | |
321 | AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x)) | |
322 | abort ();'. This reduces the runtime of the "Many lookaheads" | |
323 | test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running | |
324 | GCC 3.2. | |

326 | 2002-11-07 Paul Eggert <eggert@twinsun.com> |
327 | ||
328 | * src/parse-gram.y (CHARACTER): Remove unused token. | |
329 | All uses removed. | |
330 | ||
331 | * src/scan-gram.l: Remove stack option. We no longer use the | |
332 | stack, since the stack was never deeper than 1; instead, use the | |
333 | new auto var c_context to record the stacked value. | |
334 | ||
335 | Remove nounput option. At an unexpected end of file, we now unput | |
336 | the minimal input necessary to end cleanly; this simplifies the | |
337 | code. | |
338 | ||
339 | Avoid unbounded token sizes where this is easy. | |
340 | ||
341 | (unexpected_end_of_file): New function. | |
342 | Use it to systematize the error message on unexpected EOF. | |
343 | (last-string): Now auto, not static. | |
344 | (YY_OBS_FREE): Remove unnecessary do while (0) wrapper. | |
345 | (scanner_last_string_free): Remove; not used. | |
346 | (percent_percent_count): Move decl to just before use. | |
347 | (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file, | |
348 | not the (never otherwised-used) CHARACTER. | |

352 | Let yyerror always receive the msg as last argument, so that | |
353 | yyerror can be variadic. | |
354 | ||
355 | * data/yacc.c (b4_yyerror_args): New. | |
356 | Use it when calling yyerror. | |

e183b123 PE |
407 | * src/scan-gram.l: Use more accurate diagnostics, e.g. |
408 | "integer out of range" rather than "invalid value". | |
409 | * tests/input.at (Invalid $n, Invalid @n): Change expected wording | |
410 | accordingly. | |
411 | ||
193eb6b7 PE |
412 | Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires. |
413 | Also, remove one static variable in the scanner. | |
414 | ||
415 | * src/scan-gram.l (braces_level): Now auto, not static. | |
416 | Initialize to zero if the compiler is being picky. | |
417 | (INITIAL): Clear braces_level instead of incrementing it. | |
418 | (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code, | |
419 | as POSIX 1003.1-2001 requires. | |

439 | returns true when location & yacc & pure & parse-param. | |
440 | (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments. | |

442 | 2002-11-04 Akim Demaille <akim@epita.fr> |
443 | ||
444 | * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid | |
445 | clashes. | |
446 | * src/scan-gram.l: Use [\'] instead of ['] to pacify | |
447 | font-lock-mode. | |
448 | Use complain_at. | |
449 | Use quote, not quote_n since LOCATION_PRINT no longer uses the | |
450 | slot 0. | |

470 | Use b4_identification. | |

485 | (_AT_DATA_CALC_Y): Equip for purity of yyerror. | |
486 | (_AT_CHECK_CALC_ERROR): Use AT_YYERROR_SEES_LOC_IF. | |
487 | * tests/cxx-type.at (_AT_TEST_GLR_CALC): Equip for yyerror purity. | |
488 | * doc/bison.texinfo: Untabify the whole file. | |
489 | (Parser Function): Document %parse-param, deprecate YYPARSE_PARAM. | |

495 | ||
496 | * tests/calc.at: Change all the AT_CHECK_CALC_LALR and | |

501 | 2002-11-03 Paul Eggert <eggert@twinsun.com> |
502 | ||
503 | * src/scan-gram.l: Revamp to fix POSIX incompatibilities, | |
504 | to count columns correctly, and to check for invalid inputs. | |
9e32add8 | 505 | |
b02d90a5 PE |
506 | Use mbsnwidth to count columns correctly. Account for tabs, too. |
507 | Include mbswidth.h. | |
508 | (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS. | |
509 | (extend_location): New function. | |
510 | (YY_LINES): Remove. | |
511 | ||
512 | Handle CRLF in C code rather than in Lex code. | |
513 | (YY_INPUT): New macro. | |
514 | (no_cr_read): New function. | |
515 | ||
516 | Scan UCNs, even though we don't fully handle them yet. | |
517 | (convert_ucn_to_byte): New function. | |
518 | ||
519 | Handle backslash-newline correctly in C code. | |
520 | (SC_LINE_COMMENT, SC_YACC_COMMENT): New states. | |
521 | (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.; | |
522 | all uses changed. | |
523 | (tag, splice): New EREs. Do not allow NUL or newline in tags. | |
524 | Use {splice} wherever C allows backslash-newline. | |
525 | YY_STEP after space, newline, vertical-tab. | |
526 | ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT). | |
9e32add8 | 527 | |
b02d90a5 PE |
528 | (letter, id): Don't assume ASCII; e.g., spell out a-z. |
529 | ||
530 | ({int}, handle_action_dollar, handle_action_at): Check for integer | |
531 | overflow. | |
9e32add8 | 532 | |
b02d90a5 PE |
533 | (YY_STEP): Omit trailing semicolon, so that it's more like C. |
534 | ||
535 | (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00 | |
536 | as well as \000. Check for UCHAR_MAX, not 255. | |
537 | Allow \x with an arbitrary positive number of digits, as in C. | |
538 | Check for overflow here. | |
539 | Allow \? and UCNs, for compatibility with C. | |
540 | ||
541 | (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision | |
542 | with quote slot used by complain_at. | |
543 | ||
544 | * tests/input.at: Add tests for backslash-newline, m4 quotes | |
545 | in symbols, long literals, and funny escapes in strings. | |
546 | ||
547 | * configure.ac (jm_PREREQ_MBSWIDTH): Add. | |
548 | * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c. | |
549 | * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext. | |

551 | * m4/mbswidth.m4: New file, from GNU coreutils. | |
552 | ||
553 | * doc/bison.texinfo (Grammar Outline): Document // comments. | |
554 | (Symbols): Document that trigraphs have no special meaning in Bison, | |
555 | nor is backslash-newline allowed. | |
556 | (Actions): Document that trigraphs have no special meaning. | |
557 | ||
558 | * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove; | |
559 | no longer used. | |
560 | ||
561 | 2002-11-02 Paul Eggert <eggert@twinsun.com> | |
562 | ||
563 | * src/reader.c: Don't include quote.h; not needed. | |
564 | (get_merge_function): Reword warning to be consistent with | |
565 | type clash diagnostic in grammar_current_rule_check. | |
566 | ||
567 | * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two | |
568 | bug in trigraph handling. | |
569 | ||
570 | * src/output.c (prepare_symbols): When printing token names, | |
571 | escape "[" as "@<:@" and likewise for "]". | |
572 | ||
573 | * src/system.h (errno): Remove declaration, as we are now | |
574 | assuming C89 or better, and C89 guarantees errno. | |
575 | ||
762b212b PE |
576 | 2002-10-30 Paul Eggert <eggert@twinsun.com> |
577 | ||
578 | * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write): | |
579 | Check for close failures. | |
580 | * src/files.h (xfclose): Return void, not int, since it always | |
581 | returned zero. | |
582 | * src/files.c (xfclose): Likewise. Report I/O error if ferror | |
583 | indicates one. | |
584 | * src/output.c (output_skeleton): Use xfclose rather than fclose | |
585 | and ferror. xfclose now checks ferror. | |
586 | ||
587 | * data/glr.c (YYLEFTMOST_STATE): Remove. | |
588 | (yyreportTree): Use a stack-based leftmost state. This avoids | |
589 | our continuing battles with bogus warnings about initializers. | |
590 | ||
56100c60 AD |
591 | 2002-10-30 Akim Demaille <akim@epita.fr> |
592 | ||
593 | * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only | |
594 | #if. | |
595 | ||
51b4a04c PH |
596 | 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU> |
597 | ||

603 | ||
5c16c6b1 PE |
604 | Version 1.75a. |
605 | ||
bf1ebda2 PE |
606 | * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration. |
607 | * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since | |
608 | we use malloc. Don't assume 'A' through 'Z' are contiguous. | |
609 | Don't assume strdup exists; POSIX says its an XSI extension. | |
610 | Check for buffer overflow on input. | |
611 | ||
b526ee61 AD |
612 | 2002-10-24 Akim Demaille <akim@epita.fr> |
613 | ||
614 | * src/output.c (output_skeleton): Don't disable M4sugar comments | |
615 | too soon: it results in comments being expanded. | |
616 | * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the | |
617 | first output. | |
618 | ||
f1886bb2 AD |
619 | 2002-10-24 Akim Demaille <akim@epita.fr> |
620 | ||
621 | * data/yacc.c (m4_int_type): New. | |
622 | * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed | |
623 | char' as only yacc.c wants K&R portability. | |
624 | * data/glr.c (yysigned_char): Remove. | |
625 | * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name. | |
626 | Reported by Quoc Peyrot. | |
627 | ||
c5576256 PE |
628 | 2002-10-23 Paul Eggert <eggert@twinsun.com> |
629 | ||
630 | * src/main.c (main): With --trace=time, report times even if a | |
631 | non-fatal error occurs. Formerly, the times were reported in some | |
632 | such cases but not in others. | |
633 | * src/reader.c (reader): Just return if a complaint has been issued, | |
634 | instead of exiting, so that 'main' can report times. | |
635 | ||
27b0ffea AD |
636 | 2002-10-22 Akim Demaille <akim@epita.fr> |
637 | ||
638 | * src/system.h: Include sys/types. | |
639 | Reported by Bert Deknuydt. | |
640 | ||
223a7883 PE |
641 | 2002-10-23 Paul Eggert <eggert@twinsun.com> |
642 | ||
643 | * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX. | |
644 | Suggested by Art Haas. | |
645 | ||
646 | 2002-10-22 Paul Eggert <eggert@twinsun.com> | |
647 | ||
648 | * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit | |
649 | decl; not needed any more. | |
650 | * src/main.c (main): Use return to exit, undoing yesterday's change. | |
651 | The last OS that we could find where this wouldn't work is | |
652 | SunOS 3.5, and that's too old to worry about now. | |
653 | ||
654 | * data/glr.c (struct yyltype): Define members even when not | |
655 | doing locations. This is more consistent with yacc.c, and it | |
656 | works around the following bug reports: | |
657 | http://mail.gnu.org/pipermail/bug-bison/2002-October/001764.html | |
658 | http://mail.gnu.org/pipermail/bug-bison/2002-October/001769.html | |
659 | and I hope it also fixes this bug report: | |
660 | http://mail.gnu.org/pipermail/bug-bison/2002-October/001748.html | |
27b0ffea | 661 | |
223a7883 PE |
662 | * doc/bison.texinfo: Minor spelling and typographical fixes. Use |
663 | @acronym consistently. Standardize on "Yacc" instead of "YACC", | |
664 | "Algol" instead of "ALGOL". Give a bit more history about BNF. | |
665 | ||
8b76775a AD |
666 | 2002-10-22 Akim Demaille <akim@epita.fr> |
667 | ||
668 | * data/README: New. | |
669 | ||
6db10d14 PE |
670 | 2002-10-21 Paul Eggert <eggert@twinsun.com> |
671 | ||
672 | Be consistent about 'bool'; the old code used an enum in one | |
673 | module and an int in another, and this violates the C standard. | |
674 | * m4/stdbool.m4: New file, from coreutils 4.5.3. | |
675 | * configure.ac (AC_HEADER_STDBOOL): Add. | |
676 | * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4. | |
677 | * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a) | |
678 | * src/symtab.c (hash_compare_symbol_t): Likewise. | |
679 | * src/system.h (bool, false, true): Use a definition consistent | |
680 | with ../lib/hash.c. All uses changed. | |
681 | ||
682 | * src/complain.c (warning_issued): Renamed from warn_message_count, | |
683 | so that we needn't worry about integer overflow (!). | |
684 | Now of type bool. All uses changed. | |
685 | (complaint_issued): Renamed from complain_message_count; likewise. | |
686 | ||
687 | * src/main.c (main): Use exit to exit with failure. | |
27b0ffea | 688 | |
6db10d14 PE |
689 | * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS |
690 | rather than 1 and 0. | |
691 | * src/main.c (main): Likewise. | |
692 | * src/getargs.c (getargs): Likewise. | |
693 | * src/reader.c (reader): Likewise. | |
694 | ||
695 | * src/getarg.c (getargs): Remove duplicate code for | |
696 | "Try `bison --help'". | |
697 | ||
698 | * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2. | |
699 | What was that "2" for? | |
700 | ||
701 | * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)). | |
702 | * src/getargs.c (usage): Likewise. | |
703 | ||
704 | * src/getargs.c (getargs): When there are too few operands, report | |
705 | the last one. When there are too many, report the first extra | |
706 | one. This is how diffutils does it. | |
707 | ||
92a060fd PE |
708 | 2002-10-20 Paul Eggert <eggert@twinsun.com> |
709 | ||
710 | Remove K&R vestiges. | |
711 | * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove. | |
712 | * src/complain.c (VA_START): Remove. Assume prototypes. | |
713 | (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro. | |
714 | (private_strerror, warn_at, warn, complain_at, complain, fatal_at, | |
715 | fatal): Assume prototypes. | |
716 | * src/complain.h: Assume prototypes. | |
717 | * src/system.h (PARAMS): Remove. | |
718 | Include <limits.h> unconditionally, since it's guaranteeed even | |
719 | for a freestanding C89 compiler. | |
720 | (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them. | |
721 | * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype. | |
8b76775a | 722 | |

733 | 2002-10-20 Akim Demaille <akim@epita.fr> |
734 | ||
735 | * data/c.m4 (b4_c_ansi_args): Recognize functions with no | |
736 | arguments and output `void'. | |
737 | (b4_c_function): Rename as... | |
738 | (b4_c_function_def): this. | |
739 | (b4_c_function_decl, b4_c_ansi_function_def) | |
740 | (b4_c_ansi_function_decl): New. | |
741 | Change the interpretation of the arguments: before `int, foo', now | |

784 | Do not create a temporary file, as that involves security and | |

1030 | Let nondeterministic skeletons be usable with deterministic | |
1031 | tables. | |
1032 | ||
1033 | With the patch, GAWK compiled by GCC without -O2 passes its test | |
1034 | suite using a GLR parser driven by LALR tables. It fails with -O2 | |
1035 | because `struct stat' gives two different answers on my machine: | |
1036 | 88 (definition of an auto var) and later 96 (memset on this var). | |
1037 | Hence the stack is badly corrumpted. The headers inclusion is to | |
1038 | blame: if I move the awk.h inclusion before GLR's system header | |
1039 | inclusion, the two struct stat have the same size. | |

1076 | (yygetLRActions): Map error action number from YYTABLE from | |
1077 | YYTABLE_NINF to 0. | |
1078 | (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF | |
1079 | (which was a bug: it should have been YYTABEL_NINF, and yet it was | |
1080 | not satisfying as we could compare an YYACTION computed from | |
1081 | YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the | |
1082 | only value for error actions. | |
1083 | (yyreportParseError): In verbose parse error messages, don't issue | |
1084 | `error' in the list of expected tokens. | |

1091 | Fix problem reported by Henrik Grubbstroem in | |
1092 | <http://mail.gnu.org/pipermail/bug-bison/2002-October/001670.html>: | |
1093 | "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected, | |
1094 | because the Bison parser reads the second action before reducing | |
1095 | the first one. | |
1096 | * src/scan-gram.l (rule_length): New static var. | |
1097 | Use it to keep track of the rule length in the scanner, since | |
1098 | we can't expect the parser to be in lock-step sync with the scanner. | |
1099 | (handle_action_dollar, handle_action_at): Use this var. | |
1100 | * tests/actions.at (Exotic Dollars): Test for the problem. | |

1155 | ||
1156 | * lib/abitset.c (abitset_bytes): Return a size that is aligned | |
1157 | properly for vectors of objects. Do not assume that adding a | |
1158 | header size to a multiple of a word size yields a value that is | |

1162 | * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new, | |

1202 | Do not use "struct bitset_struct" to mean different things in | |
1203 | different modules. Not only is this confusing, it violates | |
1204 | the C Standard, which requires that structure types in different | |
1205 | modules must be compatible if one is to be passed to the other. | |
1206 | * lib/bbitset.h (bitset): Now points to a union, not to a struct. | |
1207 | All instances of "struct bitset_struct *" replaced with "bitset". | |
1208 | * lib/bitset.h (struct bitset_struct): Remove, replacing with.... | |

1222 | Do not call a function of type T using a call that assumes the | |
1223 | function is of a different type U. Standard C requires that a | |

1252 | the same width as int. This reapplies a hunk of the 2002-08-12 patch | |
1253 | <http://mail.gnu.org/pipermail/bison-patches/2002-August/001111.html>, | |

1516 | as int, and similarly for yyposn and YYINDEX. | |
1517 | ||

1521 | directory, which has been removed. | |

1567 | (_): New macro. | |
1568 | (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't | |

1594 | src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c, | |
1595 | lib/timevar.c. | |
1596 | Use src/parse-gram.y instead of src/parse-gram.c, as the gettext | |
1597 | manual recommends. | |
1598 | Similarly, use src/scan-gram.l instead of src/scan-gram.c. | |
1599 | ||
1600 | * src/complain.c (strerror_r): Remove decl; not needed. | |

1608 | to void, to avoid a GCC warning when --disable-nls is in effect. | |
1609 | ||
1610 | * src/scan-gram.l: Use strings rather than escapes when possible, | |
1611 | to minimize the number of warnings from xgettext. | |
1612 | (handle_action_dollar, handle_action_at): Don't use isdigit, | |

1614 | outside the C locale. | |
1615 | ||
1616 | * src/symtab.c (symbol_get): Don't cast LHS of an assignment; | |
1617 | this is a GCC extension and is not portable to other compilers. | |

1620 | Do not include <ctype.h>; no longer needed. | |

1622 | warnings on OpenBSD 3.0). | |

1625 | it's not portable. | |
1626 | ||
1627 | * tests/regression.at: Do not use 'cc -c input.c -o input'; | |
1628 | Sun C rejects this. Instead, use 'cc -c input.c -o input.o'. | |
1629 | ||
1630 | * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero | |
1631 | exit status as failure, not just exit status 1. Sun C exits | |
1632 | with status 2 sometimes. | |

1635 | Use it for the two large tests. | |

1802 | parsers now contain `reduce 0' as default reduction. | |
1803 | Nevertheless, since they decide to `accept' when yystate = | |

2930 | grammar. | |

3571 | * src/gram.h, src/gram.c (error_token_number): Remove, use | |
3572 | errtoken->number. | |
3573 | * src/reader.c (reader): Don't specify the user token number (2) | |
3574 | for $undefined, as it uselessly prevents using it. | |
3575 | * src/gram.h (token_number_t): Move to... | |
3576 | * src/symtab.h: here. | |
3577 | (state_t.number): Is a token_number_t. | |
3578 | * src/print.c, src/reader.c: Use undeftoken->number instead of | |
3579 | hard coded 2. | |
3580 | (Even though this 2 is not the same as above: the number of the | |
3581 | undeftoken remains being 2, it is its user token number which | |
3582 | might not be 2). | |
3583 | * src/output.c (prepare_tokens): Rename the `maxtok' muscle with | |
3584 | `user_token_number_max'. | |
3585 | Output `undef_token_number'. | |

3587 | Be sure to map invalid yylex return values to | |

3608 | positive number, and the negation of rule numbers as negative | |
3609 | numbers. | |

3622 | 500. | |
3623 | * tests/regression.at (Web2c Actions): Ajust. | |
3624 | ||
3625 | Trying with bigger grammars shows various phenomena: at 3000 (28Mb | |
3626 | of grammar file) bison is killed by my system, at 2000 (12Mb) bison | |
3627 | passes, but produces negative #line number, once fixed, GCC is | |
3628 | killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of | |

4302 | Bison dumps core when trying to complain about broken input files. | |
4303 | Reported by Cris van Pelt. | |

4342 | * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the | |
4343 | canonical definition. | |
4344 | * src/system.h: Use the canonical definition for PARAMS (avoids | |
4345 | a conflict with the macro from lib/hash.h). | |

4395 | BUILT_SOURCES, to ensure they are generated first. | |

4404 | 'switch' without a following semicolon. | |

4416 | Creating package.m4 from configure.ac causes too many problems. | |
4417 | ||

4419 | AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf. | |

4426 | 2002-01-04 Paul Eggert <eggert@twinsun.com> |
4427 | ||

4438 | * src/parse-skel.y (process_skeleton): Don't bind the parser's | |

4440 | args. | |
4441 | ||

4442 | 2002-01-03 Akim Demaille <akim@epita.fr> |
4443 | ||
4444 | * src/bison.simple (YYSTDERR): Remove, replace `stderr'. | |
4445 | The ISO C++ standard is extremely clear about it: stderr is | |
4446 | considered a macro, not a regular symbol (see table 94 `Header | |
4447 | <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files). | |
4448 | Therefore std:: does not apply to it. It still does with fprintf. | |
4449 | Also, s/cstdio.h/cstdio/. | |

4456 | 2002-01-02 Akim Demaille <akim@epita.fr> |
4457 | ||
4458 | Equip the skeleton chain with location tracking, runtime trace, | |
4459 | pure parser and scanner. | |
4460 | ||
4461 | * src/parse-skel.y: Request a pure parser, locations, and prefix | |
4462 | renaming. | |
4463 | (%union): Having several members with the same type does not help | |
4464 | type mismatches, simplify. | |
4465 | (YYPRINT, yyprint): New. | |
4466 | (yyerror): ``Rename'' (there is a #define yyerror skel_error) as... | |
4467 | (skel_error): this. | |
4468 | Handle locations. | |
4469 | * src/scan-skel.l: Adjust to these changes. | |

4474 | ||
4475 | * src/parse-skel.y: Get rid of the shift/reduce conflict: | |
4476 | replace `gb' with BLANKS. | |
4477 | * src/scan-skel.l: Adjust. | |
4478 | ||
a4b36db4 AD |
4479 | 2001-12-30 Akim Demaille <akim@epita.fr> |
4480 | ||
4481 | * src/system.h: We don't need nor want bcopy. | |
4482 | Throw away MS-DOS crap: we don't need getpid. | |
4483 | * configure.in: We don't need strndup. It was even causing | |
4484 | problems: because Flex includes the headers *before* us, | |
4485 | _GNU_SOURCE is not defined by config.h, and therefore strndup was | |
4486 | not visible. | |
4487 | * lib/xstrndup.c: New. | |
4488 | * src/scan-skel.l: Use it. | |
4489 | Be sure to initialize yylval.muscle member when scanning a MUSCLE. | |
4490 | * src/parse-skel.y: Use %directives instead of #defines. | |
4491 | ||

4494 | * src/skeleton.h: New. | |

4496 | code. | |
4497 | * src/output.h (get_lines_number, actions_output, guards_output) | |
4498 | (token_definitions_output): Prototype them. | |
4499 | * src/parse-skel.y: Add the license notice. | |
4500 | Include output.h and skeleton.h. | |
4501 | (process_skeleton): Returns void, and takes a single parameter. | |
4502 | * src/scan-skel.l: Add the license notice. | |
4503 | Include skeleton.h. | |
4504 | Don't use %option yylineno: it seems that then Flex imagines | |
4505 | REJECT has been used, and therefore it won't reallocate its | |
4506 | buffers (which makes no other sense to me than a bug). It results | |
4507 | in warnings for `unused: yy_flex_realloc'. | |

4515 | ||
4516 | * src/bison.hairy: Add a section directive. Put braces around muscle | |
4517 | names. This parser skeleton is still broken, but Bison should not | |
4518 | choke on a bad muscle 'syntax'. | |
4519 | * src/bison.simple: Add a section directive. Put braces around muscle | |
4520 | names. | |
4521 | ||
4522 | * src/files.h (strsuffix, stringappend): Add declarations. | |
4523 | (tab_extension): Add declaration. | |
4524 | (short_base_name): Add declaration. | |
4525 | ||
4526 | * src/files.c (strsuffix, stringappend): No longer static. These | |
4527 | functions are used in the skeleton parser. | |
4528 | (tab_extension): New. | |
4529 | (compute_base_names): Use the computations done in this function | |
fab5b110 | 4530 | to guess if the generated parsers should have '.tab' in their |
9b3add5b RA |
4531 | names. |
4532 | (short_base_name): No longer static. | |
4533 | ||
4534 | * src/output.c (output_skeleton): New. | |
4535 | (output): Disable call to output_master_parser, and give a try to | |
4536 | a new skeleton handling system. | |
4537 | (guards_output, actions_output): No longer static. | |
4538 | (token_definitions_output, get_lines_number): No longer static. | |

4541 | ||
fab5b110 | 4542 | * src/Makefile.am (bison_SOURCES): Add scan-skel.l and |
9b3add5b RA |
4543 | parse-skel.y. |

4545 | * src/parse-skel.y: New file. | |

4552 | * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy". | |
4553 | Adjust all dependencies. | |
4554 | * tests/headers.at (export YYLTYPE): Strengthen this test: use | |
4555 | %name-prefix. | |
4556 | ||
4557 | Renaming yylval but not yylloc is not consistent. Now we do. | |
4558 | ||

4566 | Remove all references to fixed-output-files, yacc is enough. | |
4567 | ||

4568 | 2001-12-29 Akim Demaille <akim@epita.fr> |

4579 | * tests/headers.at (export YYLTYPE): New, make sure it does. | |
4580 | * tests/regression.at (%union and --defines, Invalid CPP headers): | |

4619 | * tests/actions.at (Mid-rule actions): New. | |

4703 | the other tests pass correctly, the table look OK, even though the | |

4728 | Fix the `GAWK Grammar' failure. | |
4729 | ||
4730 | * src/LR0.c (final_state): Initialize to -1 so that we do compute | |
4731 | the reductions of the first state which was mistakenly confused | |
4732 | with the final state because precisely final_state was initialized | |

4784 | cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and | |
4785 | Sparc, as they were causing more porting problems than the | |
4786 | (minor) performance improvement was worth. | |

4793 | 0-sentinel. See below. | |
4794 | Use -1 as separator, not 0. | |
4795 | * src/bison.simple (yyparse): Subtract 1 to the rule numbers. | |
4796 | Rely on -1 as separator in yyrhs, instead of 0. | |
4797 | * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue | |
4798 | twice `Now at end of input', therefore there are two lines less to | |
4799 | expect. | |

4810 | is reached by eoftoken. | |
4811 | (insert_start_shifting_state, insert_eof_shifting_state) | |
4812 | (insert_accepting_state, augment_automaton): Remove, since now | |
4813 | these states are automatically computed from the initial state. | |
4814 | (generate_states): Adjust. | |
4815 | * src/print.c: When reporting a rule number to the user, substract | |
4816 | 1, so that the axiom rule is rule 0, and the first user rule is 1. | |
4817 | * src/reduce.c: Likewise. | |
4818 | * src/print_graph.c (print_core): For the time being, just as for | |
4819 | the report, depend upon --trace-flags to dump the full set of | |
4820 | items. | |
4821 | * src/reader.c (readgram): Once the grammar read, insert the rule | |
4822 | 0: `$axiom: START-SYMBOL $'. | |
4823 | * tests/set.at: Adjust: rule 0 is now displayed, and since the | |
4824 | number of the states has changed (the final state is no longer | |
4825 | necessarily the last), catch up. | |

4828 | ||
4829 | Try to make the use of the eoftoken valid. Given that its value | |
4830 | is 0 which was also used as a sentinel in ritem, (i) make sure >= 0 | |
4831 | is used instead of > 0 where appropriate, (ii), depend upon nritems | |
4832 | instead of the 0-sentinel. | |
4833 | ||
4834 | * src/gram.h, src/gram.c (nritems): New. | |
4835 | Expected to be duplication of nitems, but for the time being... | |

4846 | reductions, then output the report anyway if requested, then die. | |
4847 | * src/symtab.c (bucket_new): Initialize `value' to -1, not 0. | |
4848 | * src/reader.c (eoftoken): New. | |
4849 | (parse_token_decl): If the token being defined has value `0', it | |
4850 | is the eoftoken. | |
4851 | (packsymbols): No longer hack `tags' to insert `$' by hand. | |
4852 | Be sure to preserve the value of the eoftoken. | |
4853 | (reader): Make sure eoftoken is defined. | |
4854 | Initialize nsyms to 0: now eoftoken is created just like the others. | |
4855 | * src/print.c (print_grammar): Don't special case the eof token. | |
4856 | * src/regression.at: Adjust: `$' has value 0, not -1, which was a | |
4857 | lie anyway, albeit pleasant. | |
4858 | * tests/calc.at: Exercise error messages with eoftoken. | |
4859 | Change the grammar so that empty input is invalid. | |
4860 | Adjust expectations. | |
4861 | When yyungeting, be sure to use a valid yylloc: use last_yylloc. | |

4947 | members. | |

4950 | (copy_guard): Just as for actions, store the `action' only, not | |
4951 | the switch/case/break flesh. | |
4952 | Don't parse the user action that might follow the guard, let... | |

5018 | * src/output.c (prepare): Drop the muscle `ntbase' which | |
5019 | duplicates ntokens. | |
5020 | * src/bison.simple: Formatting/comment changes. | |
5021 | Use YYNTOKENS only, which is documented, but not YYNTBASE, which | |
5022 | is an undocumented synonym. | |

5025 | ||
5026 | * src/output.c (output_table_data): Change the prototype to use | |
5027 | `int' for array ranges: some invocations do pass an int, not a | |
5028 | short. | |

5033 | Some actions of web2c.y are improperly triggered. | |
5034 | Reported by Mike Castle. | |

5052 | ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__)) | |
5053 | Reported by Nelson Beebee. | |
5054 | ||

1a4648ff AD |
5149 | 2001-12-15 Akim Demaille <akim@epita.fr> |
5150 | ||
5151 | Make `make distcheck' work. | |
5152 | ||
5153 | * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses | |
5154 | system.h which uses libgettext.h. | |
5155 | ||
9c2c67e6 AD |
5156 | 2001-12-15 Akim Demaille <akim@epita.fr> |
5157 | ||
5158 | * src/nullable.c (set_nullable): Useless rules must be skipped, | |
5159 | otherwise, since we range over their symbols, we might look at a | |
5160 | nonterminal which no longer ``exists'', i.e., it is not counted in | |
5161 | `nvars', hence we overflow our arrays. | |

5166 | Yahoo! | |

5168 | * src/files.c, src/files.h (defines_obstack): Remove. | |
5169 | (compute_header_macro): Global. | |
5170 | (defines_obstack_save): Remove. | |
5171 | * src/reader.c (parse_union_decl): No longer output to | |
5172 | defines_obstack: its content can be found in the `stype' muscle | |
5173 | anyway. | |
5174 | (output_token_translations): Merge into... | |

5176 | Rename as... | |

2666f928 AD |
5182 | 2001-12-15 Akim Demaille <akim@epita.fr> |
5183 | ||
5184 | * src/reader.c (parse_union_decl): Instead of handling two obstack | |
5185 | simultaneously, use one to define the `stype' muscle, and use the | |
5186 | value of the latter to fill defines_obstack. | |
5187 | (copy_comment): Remove. | |
5188 | (copy_comment2): Work for a single obstack. | |

5198 | ||
5199 | Still making progress in separating Bison into (i) input, (ii) | |
5200 | process, (iii) output: now we can directly output the parser file | |
5201 | without using table_obstack at all. | |
5202 | ||
5203 | * src/files.c, src/files.h (table_obstack): Bye bye. | |
5204 | (parser_file_name): New. | |
5205 | * src/files.c (compute_output_file_names): Compute it. | |
5206 | * src/output.c (actions_output, output_parser) | |

5210 | ||
5211 | Attach actions to rules, instead of pre-outputting them to | |
5212 | actions_obstack. | |
5213 | ||
5214 | * src/gram.h (rule_t): action and action_line are new members. | |
5215 | * src/reader.c (symbol_list): Likewise. | |
5216 | (copy_action): Save the actions within the rule. | |
5217 | (packgram): Save them in rule_table. | |
5218 | * src/output.c (actions_output): New. | |
5219 | (output_parser): Use it on `%%actions'. | |
5220 | (output_rule_data): Don't free rule_table. | |
5221 | (output): Do it. | |
5222 | (prepare): Don't save the `action' muscle. | |
5223 | * src/bison.simple: s/%%action/%%actions/. | |

51576fb3 AD |
5225 | 2001-12-15 Akim Demaille <akim@epita.fr> |
5226 | ||
5227 | * src/reader.c (copy_action): When --yacc, don't append a `;' | |
5228 | to the user action: let it fail if lacking. | |
dee049eb | 5229 | Suggested by Arnold Robbins and Tom Tromey. |

5232 | ||
5233 | * src/lex.c (literalchar): Simply return the char you decoded, non | |
5234 | longer mess around with obstacks and int pointers. | |
5235 | Adjust all callers. | |
5236 | ||
92790e5b AD |
5237 | 2001-12-14 Akim Demaille <akim@epita.fr> |
5238 | ||
5239 | * src/lex.c (literalchar): Don't escape the special characters, | |
5240 | just decode them, and keep them as char (before, eol was output as | |
5241 | the 2 char string `\n' etc.). | |
5242 | * src/output.c (output_rule_data): Use quotearg to output the | |
5243 | token strings. | |

5245 | 2001-12-13 Paul Eggert <eggert@twinsun.com> |
5246 | ||
5247 | * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE): | |
5248 | Do not infringe on the global user namespace when using C++. | |
5249 | (YYFPRINTF, YYSTDERR): New macros, needed for the above. | |
5250 | All uses of `fprintf' and `stderr' changed. | |
5251 | ||
5252 | * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR. | |

5255 | ||
5256 | The computation of nullable is broken: it doesn't handle empty | |
5257 | RHS's properly. | |
5258 | ||
5259 | * tests/torture.at (GNU AWK Grammar): New. | |
5260 | * tests/sets.at (Nullable): New. | |
5261 | * src/nullable.c (set_nullable): Instead of blindly looping over | |
5262 | `ritems', loop over the rules, and then over their rhs's. | |
5263 | ||
5264 | Work around Autotest bugs. | |
5265 | ||
5266 | * src/warshall.c (bitmatrix_print): Don't use `+--+' as table | |
5267 | frame, because Autotest understand lines starting with a `+' as | |
5268 | traces from the shell. Then, they are not processed properly. | |
5269 | Admittedly an Autotest bug, but we don't have time to wait for | |
5270 | Autotest to catch up. | |
5271 | * tests/regression.at (Broken Closure): Adjust to the new table | |
5272 | frames. | |
5273 | Move to... | |
5274 | * tests/sets.at: here. | |

cb581495 AD |
5276 | 2001-12-13 Akim Demaille <akim@epita.fr> |
5277 | ||
5278 | * src/closure.c (closure): Use nrules instead of playing tricks | |
5279 | with BITS_PER_WORD. | |
5280 | ||
2e729273 AD |
5281 | 2001-12-13 Akim Demaille <akim@epita.fr> |
5282 | ||
5283 | * src/print.c (print_actions): Output the handling of `$' as the | |
5284 | traces do: shifting the token EOF. Before EOF was treated as a | |
5285 | nonterminal. | |
5286 | * tests/regression.at: Adjust some tests. | |
5287 | * src/print_graph.c (print_core): Complete the set of items via | |
5288 | closure. The next-to-final and final states are still unsatisfying, | |
5289 | but that's to be addressed elsewhere. | |
5290 | No longer output the rule numbers, but do output the state number. | |
5291 | A single loop for the shifts + gotos is enough, but picked a | |
5292 | distinct color for each. | |
5293 | (print_graph): Initialize and finalize closure. | |

107f7dfb AD |
5295 | 2001-12-13 Akim Demaille <akim@epita.fr> |

9b53a24f AD |
5301 | 2001-12-12 Akim Demaille <akim@epita.fr> |
5302 | ||
5303 | * src/complain.h, src/complain.c: Remove error_one_per_line, rely | |
5304 | on that of lib/error.c. | |
5305 | ||
dbfb6dcd AD |
5306 | 2001-12-12 Akim Demaille <akim@epita.fr> |
5307 | ||
5308 | Some hosts don't like `/' in includes. | |
5309 | ||
5310 | * src/system.h: Include libgettext.h without qualifying the path. | |
5311 | * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove | |
5312 | $(top_srcdir). | |

e83d80b8 MA |

5343 | 2001-12-10 Akim Demaille <akim@epita.fr> |
5344 | ||
5345 | * src/state.h (shifts): Remove the `number' member: shifts are | |
5346 | attached to state, hence no longer need to be labelled with a | |
5347 | state number. | |
5348 | ||
190c4f5f AD |
5349 | 2001-12-10 Akim Demaille <akim@epita.fr> |
5350 | ||
5351 | Now that states have a complete set of members, the linked list of | |
5352 | shifts is useless: just fill directly the state's shifts member. | |
5353 | ||
5354 | * src/state.h (shifts): Remove the `next' member. | |
5355 | * src/LR0.c (first_state, last_state): Remove. | |
5356 | Adjust the callers. | |
5357 | (augment_automaton): Don't look for the shifts that must be added | |
5358 | a shift on EOF: it is those of the state we looked for! But now, | |
5359 | since shifts are attached, it is no longer needed to looking | |
5360 | merely by its id: its number. | |
5361 | ||
2a73b93d AD |
5362 | 2001-12-10 Akim Demaille <akim@epita.fr> |
5363 | ||
5364 | * src/LR0.c (augment_automaton): Better variable locality. | |
5365 | Remove an impossible branch: if there is a state corresponding to | |
5366 | the start symbol being shifted, then there is shift for the start | |
5367 | symbol from the initial state. | |
5368 | ||
74392f6a AD |
5369 | 2001-12-10 Akim Demaille <akim@epita.fr> |
5370 | ||
5371 | * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state' | |
5372 | only when appropriate: when insert_start_shifting_state' is not | |
5373 | invoked. | |
5374 | * tests/regression.at (Rule Line Numbers): Adjust. | |
5375 | ||
37c82725 AD |
5376 | 2001-12-10 Akim Demaille <akim@epita.fr> |
5377 | ||

5386 | * src/LR0.c (generate_states): do it. | |
5387 | * src/LR0.h (first_state): Remove, only the table is used. | |

5391 | * src/LR0.h (first_shift, first_reduction): Remove. | |
5392 | * src/lalr.c: Don't use first_shift: find shifts through the | |
5393 | states. | |

5396 | ||
5397 | * src/LR0.c: Attach shifts to states as soon as they are | |
5398 | computed. | |
5399 | * src/lalr.c (set_state_table): Instead of assigning shifts to | |
5400 | state, just assert that the mapping was properly done. | |

5404 | * src/LR0.c (insert_start_shift): Rename as... | |
5405 | (insert_start_shifting_state): this. | |
5406 | (insert_eof_shifting_state, insert_accepting_state): New. | |
5407 | (augment_automaton): Adjust. | |
5408 | Better locality of the variables. | |
5409 | When looking if the start_symbol is shifted from the initial | |
5410 | state, using `while (... symbol != start_symbol ...)' sounds | |
5411 | better than `while (... symbol < start_symbol ...)': If fail | |
5412 | to see how the order between symbols could be relevant! | |

5416 | * src/getargs.h: Don't declare `spec_name_prefix' and | |
5417 | `spec_file_prefix', declared by src/files.h. | |
5418 | * src/files.c, src/files.h: Default for spec_name_prefix is "yy". | |
5419 | * src/muscle_tab.c (muscle_init): Default prefix to NULL. | |
5420 | * src/output.c (prepare): Adjust. | |
5421 | * src/reader.c (symbols_output): Likewise. | |
5422 | * src/vmsgetargs.c: Vaguely adjust, but who cares? | |

5425 | ||
5426 | * src/muscle_tab.c (muscle_init): NULL is a better default than | |
5427 | `"0"'. | |

5434 | ||
5435 | Now that states have a complete set of members, the linked list of | |
5436 | reductions is useless: just fill directly the state's reductions | |
5437 | member. | |
5438 | ||
5439 | * src/state.h (struct reductions): Remove member `number' and | |
5440 | `next'. | |
5441 | * src/LR0.c (first_reduction, last_reduction): Remove. | |
5442 | (save_reductions): Don't link the new reductions, store them in | |
5443 | this_state. | |
5444 | * src/lalr.c (set_state_table): No need to attach reductions to | |
5445 | states, it's already done. | |
5446 | * src/output.c (output_actions): No longer free the shifts, then | |
5447 | the reductions, then the states: free all the states and their | |
5448 | members. | |

5453 | (option_table): Use them. | |
5454 | ||

5455 | * src/muscle_tab.c: Don't include xalloc.h and string.h: that's |
5456 | the job of system.h. | |
5457 | * src/options.c: Don't include stdio.h and xalloc.h for the same | |
5458 | reasons. | |

5469 | * src/reader.c (copy_action): `buf' is not used. | |
5470 | (parse_skel_decl): Be static. | |
5471 | * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'. | |
5472 | * src/options.h (create_long_option_table): Have a real prototype. | |
5473 | * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete) | |
5474 | (hash_delete_at): Return const void *. | |
5475 | Adjust casts to preserve the const. | |

5486 | One structure for states is enough, even though theoretically | |
5487 | there are LR(0) states and LALR(1) states. | |
5488 | ||
5489 | * src/lalr.h (state_t): Remove. | |
5490 | (state_table): Be state_t **, not state_t *. | |
5491 | * src/state.h (core, CORE_ALLOC): Rename as... | |
5492 | (state_t, STATE_ALLOC): this. | |
5493 | Add the LALR(1) members: shifts, reductions, errs. | |
5494 | * src/LR0.c (state_table): Rename as... | |
5495 | (state_hash): this, to avoid name clashes with the global | |
5496 | `state_table'. | |
5497 | * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c | |
5498 | * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust. | |

5507 | When performing a transitive closure R(i, j) && R(j, k) => R(i, k), | |
