  • 52489d4445 Normalize conflict related messages. * src/complain.h, src/complain.c (warn, complain): New. * src/conflicts.c (conflicts_print): Use them. (conflict_report_yacc): New, extracted from... (conflicts_print): here. * tests/conflicts.at, tests/existing.at: Adjust. Akim Demaille 2002-07-30 11:09:59 +00:00
  • e8832397ea Report rules which are never reduced by the parser: those hidden by conflicts. * src/LR0.c (save_reductions): Don't make the final state too different: save its reduction (accept) instead of having a state without any action (no shift or goto, no reduce). Note: the final state is now a `regular'' state, i.e., the parsers now contain reduce 0' as default reduction. Nevertheless, since they decide to `accept' when yystate = final_state, they still will not reduce rule 0. * src/print.c (print_actions, print_reduction): Adjust. * src/output.c (action_row): Track reduced rules. (token_actions): Report rules never reduced. * tests/conflicts.at, tests/regression.at: Adjust. Akim Demaille 2002-07-30 11:06:50 +00:00
  • caf23d249c `stage' was accidently included in a previous patch. Initiate its autoconfiscation. * configure.in: Look for malloc.h and sys/times.h. * src/main.c (stage): Adjust. Report only when trace_flag. Akim Demaille 2002-07-30 08:15:04 +00:00
  • 640748eecf * src/state.h, src/state.c (transitions_t): Holds state_t*'s, not state_number_t. (errs_t): symbol_t*, not symbol_number_t. (reductions_t): rule_t*, not rule_number_t. (FOR_EACH_SHIFT): New. * src/LR0.c, src/conflicts.c, src/lalr.c, src/output.c * src/print.c, src/print_graph.c: Adjust. Akim Demaille 2002-07-29 17:31:46 +00:00
  • 88bce5a2ef Use $accept and $end, as BYacc and BTYacc do, instead of $axiom and $. * src/symtab.h, src/symtab.c (eoftoken, axiom): Rename as... (endtoken, accept): these. * src/reader.c (reader): Set endtoken's default tag to "$end". Set undeftoken's tag to "$undefined" instead of "$undefined.". * doc/bison.texinfo (Table of Symbols): Mention $accept and $end. Adjust. Akim Demaille 2002-07-29 17:30:33 +00:00
  • 1bfb97dba5 * src/reduce.c (reduce_grammar): When the language is empty, complain about the start symbol, not the axiom. Use its location. * tests/reduce.at (Empty Language): New. Akim Demaille 2002-07-29 17:28:56 +00:00
  • fc5734fe23 * src/reader.h, src/reader.c (gram_error): ... can't get yycontrol without making too strong assumptions on the parser itself. * src/output.c (prepare_tokens): Use the real 0th value of token_translations instead of `0'. * src/parse-gram.y (yyerror): Don't rely on yycontrol being visible here. * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc for the time being: %locations ought to provide it to yyerror. Akim Demaille 2002-07-26 06:25:35 +00:00
  • 3650b4b8dd * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1. * doc/bison.texinfo (Decl Summary): s/$illegal/$undefined./. * tests/regression.at (Web2c Actions): Adjust. Akim Demaille 2002-07-26 06:24:11 +00:00
  • 4b3d3a8e46 Stop storing rules from 1 to nrules + 1. * src/LR0.c, src/closure.c, src/derives.c, src/gram.c, src/lalr.c * src/nullable.c, src/output.c, src/print.c, src/reader.c * src/reduce.c: Allocate and free from &rules[0], not &rules[1]. Iterate from 0 to nrules. Use rule_number_as_item_number and item_number_as_rule_number. Adjust to derive' now containing possibly 0. * src/gram.h (rule_number_as_item_number, item_number_as_rule_number): Handle the - 1' part in rule numbers from/to item numbers. * src/conflicts.c (log_resolution): Fix the message which reversed shift and reduce. * src/output.c (action_row): Initialize default_rule to -1. (token_actions): Adjust. * tests/sets.at (Nullable, Firsts): Fix the previously bogus expected output. * tests/conflicts.at (Resolved SR Conflicts): Likewise. Akim Demaille 2002-07-25 21:21:02 +00:00
  • 4a2a22f4c0 * data/c.m4 (b4_c_function, b4_c_ansi_args, b4_c_ansi_arg) (b4_c_knr_arg_names, b4_c_knr_arg_name, b4_c_knr_arg_decls) (b4_c_knr_arg_decl): New. * data/yacc.c: Use it to define yysymprint, yydestruct, and yyreport_parse_error. Akim Demaille 2002-07-25 19:34:54 +00:00
