+2002-04-10 Akim Demaille <akim@epita.fr>
+
+ * src/system.h: Rely on HAVE_LIMITS_H.
+ Suggested by Paul Eggert.
+
+2002-04-09 Akim Demaille <akim@epita.fr>
+
+ * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
+ full stderr, and strip it according to the bison options, instead
+ of composing the error message from different bits.
+ This makes it easier to check for several error messages.
+ Adjust all the invocations.
+ Add an invocation exercising the error token.
+ Add an invocation demonstrating a stupid error message.
+ (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
+ Adjust the tests.
+ Error message are for stderr, not stdout.
+
+2002-04-09 Akim Demaille <akim@epita.fr>
+
+ * src/gram.h, src/gram.c (error_token_number): Remove, use
+ errtoken->number.
+ * src/reader.c (reader): Don't specify the user token number (2)
+ for $undefined, as it uselessly prevents using it.
+ * src/gram.h (token_number_t): Move to...
+ * src/symtab.h: here.
+ (state_t.number): Is a token_number_t.
+ * src/print.c, src/reader.c: Use undeftoken->number instead of
+ hard coded 2.
+ (Even though this 2 is not the same as above: the number of the
+ undeftoken remains being 2, it is its user token number which
+ might not be 2).
+ * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
+ `user_token_number_max'.
+ Output `undef_token_number'.
+ * data/bison.simple, data/bison.c++: Use them.
+ Be sure to map invalid yylex return values to
+ `undef_token_number'. This saves us from gratuitous SEGV.
+
+ * tests/conflicts.at (Solved SR Conflicts)
+ (Unresolved SR Conflicts): Adjust.
+ * tests/regression.at (Web2c Actions): Adjust.
+
+2002-04-08 Akim Demaille <akim@epita.fr>
+
+ * data/bison.c++: s/b4_item_number_max/b4_rhs_number_max/.

+ Remove the duplicate `typedefs'.
+ (RhsNumberType): Fix the declaration and various other typos.
+ Use __ofile__.

+
+2002-04-08 Akim Demaille <akim@epita.fr>
+
+ * src/gram.h (item_number_t): New, the type of item numbers in
+ RITEM. Note that it must be able to code symbol numbers as
+ positive number, and the negation of rule numbers as negative
+ numbers.
+ Adjust all dependencies (pretty many).
+ * src/reduce.c (rule): Remove this `short *' pointer: use
+ item_number_t.
+ * src/system.h (MINSHORT, MAXSHORT): Remove.
+ Include `limits.h'.
+ Adjust dependencies to using SHRT_MAX and SHRT_MIN.
+ (shortcpy): Remove.
+ (MAXTABLE): Move to...
+ * src/output.c (MAXTABLE): here.
+ (prepare_rules): Use output_int_table to output rhs.
+ * data/bison.simple, data/bison.c++: Adjust.
+ * tests/torture.at (Big triangle): Move the limit from 254 to
+ 500.
+ * tests/regression.at (Web2c Actions): Ajust.
+
+ Trying with bigger grammars shows various phenomena: at 3000 (28Mb
+ of grammar file) bison is killed by my system, at 2000 (12Mb) bison
+ passes, but produces negative #line number, once fixed, GCC is
+ killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
+ C), it passes.
+ * src/state.h (state_h): Code input lines on ints, not shorts.
+
+2002-04-08 Akim Demaille <akim@epita.fr>
+
+ * src/reduce.c (reduce_grammar): First reduce the nonterminals,
+ and then the grammar.
+
+2002-04-08 Akim Demaille <akim@epita.fr>
+
+ * src/system.h: No longer using strndup.
+
+2002-04-07 Akim Demaille <akim@epita.fr>
+
+ * src/muscle_tab.h (MUSCLE_INSERT_LONG_INT): New.
+ * src/output.c (output_table_data): Return the longest number.
+ (prepare_tokens): Output `token_number_max').
+ * data/bison.simple, data/bison.c++ (b4_sint_type, b4_uint_type):
+ New.
+ Use them to define yy_token_number_type/TokenNumberType.
+ Use this type for yytranslate.
+ * tests/torture.at (Big triangle): Push the limit from 124 to
+ 253.
+ * tests/regression.at (Web2c Actions): Adjust.
+
+2002-04-07 Akim Demaille <akim@epita.fr>

+ (error_token_number): Initialize.
+ * src/reader.c (grammar, start_flag, startval, typed, lastprec):
+ Initialize.

+ (errtoken, eoftoken, undeftoken, axiom): Extern.
+
+2002-04-07 Akim Demaille <akim@epita.fr>
+
+ * src/gram.h (rule_s): prec and precsym are now pointers
+ to the bucket giving the priority/associativity.
+ Member `associativity' removed: useless.
+ * src/reduce.c, src/conflicts.c: Adjust.
+
+2002-04-07 Akim Demaille <akim@epita.fr>
+
+ * src/lalr.c, src/LR0.c, src/closure.c, src/gram.c, src/reduce.c:

+2002-04-07 Akim Demaille <akim@epita.fr>
+
+ As a result of the previous patch, it is no longer needed
+ to reorder ritem itself.
+
+ * src/reduce.c (reduce_grammar_tables): Don't sort RITEM.
+
+2002-04-07 Akim Demaille <akim@epita.fr>
+
+ Be sure never to walk through RITEMS, but use only data related to
+ the rules themselves. RITEMS should be banished.
+
+ * src/output.c (output_token_translations): Rename as...
+ (prepare_tokens): this.
+ In addition to `translate', prepare the muscles `tname' and

+
+2002-04-07 Akim Demaille <akim@epita.fr>
+
+ * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
