+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * tests/regression.at (Web2c Actions): Blindly move the actual
+ output as expected output. The contents *seem* right to me, but I
+ can't pretend reading perfectly parser tables... Nonetheless, all
+ the other tests pass correctly, the table look OK, even though the
+ presence of `$axiom' is to be noted: AFAICS it is useless (but
+ harmless).

+
+ * src/reader.c (readgram): Don't add the rule 0 if there were no
+ rules read. In other words, add it _after_ having performed
+ grammar sanity checks.
+ Fixes the `tests/regression.at (Invalid input: 1)' Failure.
+
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
+ visible, and some states have now a different number.

+
+ * src/reader.c (readgram): Bind the initial rule's lineno to that

+ (Solved SR Conflicts): Adjust rule 0's line number.
+
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ Fix the `GAWK Grammar' failure.
+
+ * src/LR0.c (final_state): Initialize to -1 so that we do compute
+ the reductions of the first state which was mistakenly confused
+ with the final state because precisely final_state was initialized
+ to 0.
+ * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
+ now noticed by Bison.
+ * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
+ have a reduction on $default.
+

+
+ * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
+ rule line numbers.

+ * src/derives.c (print_derives): Likewise.
+ * tests/sets.at (Nullable): Adjust: the rule numbers are correct
+ now.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/lalr.c (lookaheads_print): New.
+ (lalr): Call it when --trace-flag.

+
+ * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
+ when walking through ritem, even via rule->rhs.
+ * src/reduce.c (dump_grammar, useful_production, reduce_output)
+ (useful_production, useless_nonterminals): Likewise.
+ (reduce_grammar_tables): Likewise, plus update nritems.
+ * src/nullable.c (set_nullable): Likewise.
+ * src/lalr.c (build_relations): Likewise.
+ * tests/sets.at (Nullable): Adjust.
+ Fortunately, now, the $axiom is no longer nullable.

+
+ * src/LR0.c (generate_states): Use nritems, not nitems, nor using

+
+2001-12-27 Paul Eggert <eggert@twinsun.com>
+
+ * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
+ cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
+ Sparc, as they were causing more porting problems than the
+ (minor) performance improvement was worth.
+
+ Also, catch up with 1.31's YYSTD.
+
+2001-12-27 Akim Demaille <akim@epita.fr>
+
+ * src/output.c (output_gram): Rely on nritems, not the
+ 0-sentinel. See below.
+ Use -1 as separator, not 0.
+ * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
+ Rely on -1 as separator in yyrhs, instead of 0.
+ * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
+ twice `Now at end of input', therefore there are two lines less to
+ expect.

2001-12-27 Akim Demaille <akim@epita.fr>
* tests/regression.at (Unresolved SR Conflicts):
(Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
below.
-
- * src/LR0.c (new_state): Recognize the final state by the fact it
- is reached by eoftoken.
- (insert_start_shifting_state, insert_eof_shifting_state)
- (insert_accepting_state, augment_automaton): Remove, since now
- these states are automatically computed from the initial state.
- (generate_states): Adjust.
- * src/print.c: When reporting a rule number to the user, substract
- 1, so that the axiom rule is rule 0, and the first user rule is 1.
- * src/reduce.c: Likewise.
- * src/print_graph.c (print_core): For the time being, just as for
- the report, depend upon --trace-flags to dump the full set of
- items.
- * src/reader.c (readgram): Once the grammar read, insert the rule
- 0: `$axiom: START-SYMBOL $'.
- * tests/set.at: Adjust: rule 0 is now displayed, and since the
- number of the states has changed (the final state is no longer
- necessarily the last), catch up.
- * tests/regression.at: Partly catch up.
