+2002-07-31 Akim Demaille <akim@epita.fr>
+
+ Steal GCC's --time-report support.
+
+ * lib/timevar.c, lib/timevar.h, lib/timevar.def: New,
+ stolen/adjusted from GCC.
+ * m4/stage.m4: Remove time related checks.
+ * m4/timevar.m4: New.
+ * configure.in: Adjust.
+ * src/system.h: Adjust to using timevar.h.
+ * src/getargs.h, src/getargs.c: Support trace_time for
+ --trace=time.
+ * src/main.c (stage): Remove.
+ (main): Replace `stage' invocations with timevar calls.
+ * src/output.c: Insert pertinent timevar calls.
+
+2002-07-31 Akim Demaille <akim@epita.fr>
+
+ Let --trace have arguments.
+
+ * src/getargs.h (enum trace_e): New.
+ * src/getargs.c (trace_args, trace_types, trace_argmatch): New.
+ (long_options, short_options): --trace/-T takes an optional
+ argument.
+ Change all the uses of trace_flag to reflect the new flags.
+ * tests/sets.at (Firsts, Nullable, Broken Closure): Use --trace=sets.
+
+ Strengthen `stage' portability.
+
+ * m4/stage.m4 (BISON_PREREQ_STAGE): New.
+ * configure.in: Use it.
+ Don't check for malloc.h and sys/times.h.
+ * src/system.h: Include them when appropriate.
+ * src/main.c (stage): Compile only when mallinfo, struct mallinfo,
+ times and struct tms are available.
+
+2002-07-30 Akim Demaille <akim@epita.fr>
+
+ In verbose parse error message, don't report `error' as an
+ expected token.
+ * tests/actions.at (Printers and Destructors): Adjust.
+ * tests/calc.at (Calculator $1): Adjust.
+ * data/yacc.c, data/glr.c, data/lalr1.c: When making the verbose
+ error message, do not report the parser accepts the error token in
+ that state.
+
+2002-07-30 Akim Demaille <akim@epita.fr>
+
+ Normalize conflict related messages.
+
+ * src/complain.h, src/complain.c (warn, complain): New.

+
+2002-07-30 Akim Demaille <akim@epita.fr>
+
+ 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.

+ * src/symtab.h, src/symtab.c (eoftoken, axiom): Rename as...
+ (endtoken, accept): these.
+ * src/reader.c (reader): Set endtoken's default tag to "$end".

+
+2002-07-29 Akim Demaille <akim@epita.fr>
+

+ itself.

+ 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.
+
+2002-07-25 Akim Demaille <akim@epita.fr>
+
+ * 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.
+
+2002-07-25 Akim Demaille <akim@epita.fr>

+ * src/nullable.c, src/output.c, src/print.c, src/reader.c
