+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

+ 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

+
+2001-12-27 Akim Demaille <akim@epita.fr>
+

+ (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.
+
+2001-12-27 Akim Demaille <akim@epita.fr>
+
+ Try to make the use of the eoftoken valid. Given that its value
+ is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
+ is used instead of > 0 where appropriate, (ii), depend upon nritems
+ instead of the 0-sentinel.
+
+ * src/gram.h, src/gram.c (nritems): New.
+ Expected to be duplication of nitems, but for the time being...
+ * src/reader.c (packgram): Assert nritems and nitems are equal.
+ * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.

+ * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
+ * src/reader.c (eoftoken): New.
+ (parse_token_decl): If the token being defined has value `0', it
+ is the eoftoken.
+ (packsymbols): No longer hack `tags' to insert `$' by hand.
+ Be sure to preserve the value of the eoftoken.
+ (reader): Make sure eoftoken is defined.
+ Initialize nsyms to 0: now eoftoken is created just like the others.
+ * src/print.c (print_grammar): Don't special case the eof token.
+ * src/regression.at: Adjust: `$' has value 0, not -1, which was a
+ lie anyway, albeit pleasant.
+ * tests/calc.at: Exercise error messages with eoftoken.
+ Change the grammar so that empty input is invalid.
+ Adjust expectations.
+ When yyungeting, be sure to use a valid yylloc: use last_yylloc.

+
+ * src/gram.h (rule_t): `guard' and `guard_line' are new members.

+ (symbol_list_new): Adjust.
+ (copy_action): action_line is the first line, not the last.
+ (copy_guard): Just as for actions, store the `action' only, not
+ the switch/case/break flesh.
+ Don't parse the user action that might follow the guard, let...
+ (readgram): do it, i.e., now, there can be an action after a
+ guard.
+ In other words the guard is just explicitly optional.
+ (packgram): Adjust.
+ * src/output.c (guards_output): New.
+ (output_parser): Call it when needed.
+ (output): Also free the guard and attrs obstacks.
+ * src/files.c, src/files.h (obstack_save): Remove.
+ (output_files): Remove.
+ As a result, if one needs the former `.act' file, using an

+ required.
+ * src/main.c (main): Adjust.
+ * tests/semantic.at: New.
+ * tests/regression.at: Use `input.y' as input file name.

+ (count_sr_conflicts, count_rr_conflicts, conflicts_output)
+ (conflicts_print, print_reductions): Use a state_t instead of an
+ integer when referring to a state.
+ As much as possible, depend upon nlookaheads, instead of the
+ `lookaheadsp' member of the following state (since lookaheads of
+ successive states are successive, the difference between state n + 1
+ and n served as the number of lookaheads for state n).

+2001-12-22 Akim Demaille <akim@epita.fr>

+
+2001-12-17 Paul Eggert <eggert@twinsun.com>
+
+ * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that

+ * src/output.c (actions_output): Fix. When we use %no-lines,
+ there is one less line per action.
+
+2001-12-16 Marc Autret <autret_m@epita.fr>
+
+ * src/bison.simple: Remove a useless #line directive.
+ s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
+ * src/output.c (get_lines_number): New.
+ (output_parser): Adjust, now takes care about the lines of a
+ output muscles.
+ Fix line numbering.
+ (actions_output): Computes the number of lines taken by actions.
+ (output_master_parser): Insert new skeleton which is the name of
+ the output parser file name.

+2001-12-15 Marc Autret <autret_m@epita.fr>
+

+2001-12-15 Akim Demaille <akim@epita.fr>
+
+ Make `make distcheck' work.
+
+ * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
+ system.h which uses libgettext.h.
+
+2001-12-15 Akim Demaille <akim@epita.fr>
+
+ * src/nullable.c (set_nullable): Useless rules must be skipped,
+ otherwise, since we range over their symbols, we might look at a
+ nonterminal which no longer ``exists'', i.e., it is not counted in
+ `nvars', hence we overflow our arrays.
+
+2001-12-15 Akim Demaille <akim@epita.fr>
+
+ The header can also be produced directly, without any obstack!
+ Yahoo!
+
+ * src/files.c, src/files.h (defines_obstack): Remove.
+ (compute_header_macro): Global.
+ (defines_obstack_save): Remove.
+ * src/reader.c (parse_union_decl): No longer output to

+ Rename as...

+ (reader): Adjust.

+2001-12-15 Akim Demaille <akim@epita.fr>
+
+ * src/reader.c (parse_union_decl): Instead of handling two obstack
+ simultaneously, use one to define the `stype' muscle, and use the
+ value of the latter to fill defines_obstack.
+ (copy_comment): Remove.

+
+ Still making progress in separating Bison into (i) input, (ii)
+ process, (iii) output: now we can directly output the parser file
+ without using table_obstack at all.
+
+ * src/files.c, src/files.h (table_obstack): Bye bye.
+ (parser_file_name): New.
+ * src/files.c (compute_output_file_names): Compute it.
+ * src/output.c (actions_output, output_parser)
+ (output_master_parser): To a file instead of an obstack.

+2001-12-15 Akim Demaille <akim@epita.fr>
+
+ Attach actions to rules, instead of pre-outputting them to
+ actions_obstack.
+
+ * src/gram.h (rule_t): action and action_line are new members.
+ * src/reader.c (symbol_list): Likewise.
+ (copy_action): Save the actions within the rule.
+ (packgram): Save them in rule_table.
+ * src/output.c (actions_output): New.
+ (output_parser): Use it on `%%actions'.
+ (output_rule_data): Don't free rule_table.
+ (output): Do it.
+ (prepare): Don't save the `action' muscle.
+ * src/bison.simple: s/%%action/%%actions/.
+
+2001-12-15 Akim Demaille <akim@epita.fr>
+
+ * src/reader.c (copy_action): When --yacc, don't append a `;'
+ to the user action: let it fail if lacking.
+ Suggested by Arnold Robbins and Tom Tromey.
+
+2001-12-14 Akim Demaille <akim@epita.fr>
+
+ * src/lex.c (literalchar): Simply return the char you decoded, non
+ longer mess around with obstacks and int pointers.
+ Adjust all callers.
+
+2001-12-14 Akim Demaille <akim@epita.fr>
+
+ * src/lex.c (literalchar): Don't escape the special characters,
+ just decode them, and keep them as char (before, eol was output as
+ the 2 char string `\n' etc.).
+ * src/output.c (output_rule_data): Use quotearg to output the
+ token strings.
+
+2001-12-13 Paul Eggert <eggert@twinsun.com>
+
+ * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
+ Do not infringe on the global user namespace when using C++.
+ (YYFPRINTF, YYSTDERR): New macros, needed for the above.
+ All uses of `fprintf' and `stderr' changed.
+
+ * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
