+
+ 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
+ defines_obstack: its content can be found in the `stype' muscle
+ anyway.
+ (output_token_translations): Merge into...
+ (symbols_output): this.
+ Rename as...
+ (symbols_save): this.
+ (reader): Adjust.
+ * src/output.c (header_output): New.
+ (output): Call it.
+
+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.
+ (copy_comment2): Work for a single obstack.
+ Rename as...

+
+ 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.

+ Attach actions to rules, instead of pre-outputting them to

+
+ * 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.

+ * 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 Aharon Robbins and Tom Tromey.
+
+2001-12-14 Akim Demaille <akim@epita.fr>
+
+ * src/lex.c (literalchar): Simply return the char you decoded, non

+ 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):

+ * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
+
+2001-12-13 Akim Demaille <akim@epita.fr>
+
+ The computation of nullable is broken: it doesn't handle empty
+ RHS's properly.
+
+ * tests/torture.at (GNU AWK Grammar): New.
+ * tests/sets.at (Nullable): New.
+ * src/nullable.c (set_nullable): Instead of blindly looping over
+ `ritems', loop over the rules, and then over their rhs's.
+
+ Work around Autotest bugs.
+
+ * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
+ frame, because Autotest understand lines starting with a `+' as
+ traces from the shell. Then, they are not processed properly.
+ Admittedly an Autotest bug, but we don't have time to wait for
+ Autotest to catch up.
+ * tests/regression.at (Broken Closure): Adjust to the new table
+ frames.
+ Move to...
+ * tests/sets.at: here.
+
+2001-12-13 Akim Demaille <akim@epita.fr>
+
+ * src/closure.c (closure): Use nrules instead of playing tricks
+ with BITS_PER_WORD.
+
+2001-12-13 Akim Demaille <akim@epita.fr>
+
+ * src/print.c (print_actions): Output the handling of `$' as the
+ traces do: shifting the token EOF. Before EOF was treated as a
+ nonterminal.
+ * tests/regression.at: Adjust some tests.
+ * src/print_graph.c (print_core): Complete the set of items via
+ closure. The next-to-final and final states are still unsatisfying,
+ but that's to be addressed elsewhere.
+ No longer output the rule numbers, but do output the state number.
+ A single loop for the shifts + gotos is enough, but picked a
+ distinct color for each.
+ (print_graph): Initialize and finalize closure.

+
+ * src/reader.c (readgram): Remove dead code, an strip useless
+ braces.
+ (get_type): Remove, unused.
+
+2001-12-12 Akim Demaille <akim@epita.fr>
+
+ * src/complain.h, src/complain.c: Remove error_one_per_line, rely
+ on that of lib/error.c.

+
+ Some hosts don't like `/' in includes.
+
+ * src/system.h: Include libgettext.h without qualifying the path.
+ * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove

+ * src/reader.c (read_additionnal_code): Add the output of a
+ #line for the epilogue.
+
+2001-12-10 Marc Autret <autret_m@epita.fr>
+
+ * src/reader.c (copy_definition): Re-use CPP-outed code which
+ replace precedent remove.
+ * src/bison.simple: Remove #line before %%prologue because
+ %%input-line is wrong at this time.
+
+2001-12-10 Marc Autret <autret_m@epita.fr>

* src/LR0.h (first_shift, first_reduction): Remove.
* src/lalr.c: Don't use first_shift: find shifts through the
states.
-
2001-12-10 Akim Demaille <akim@epita.fr>
* src/LR0.c: Attach shifts to states as soon as they are
* src/lalr.c (set_state_table): Instead of assigning shifts to
state, just assert that the mapping was properly done.

* src/LR0.c (insert_start_shift): Rename as...

* src/muscle_tab.c (muscle_init): NULL is a better default than
`"0"'.

* src/reader.c (reader): Calling symbols_output once is enough.
-

Now that states have a complete set of members, the linked list of
the reductions, then the states: free all the states and their
members.

* src/options.c (OPTN, DRTV, BOTH): New.
(option_table): Use them.
-
* src/muscle_tab.c: Don't include xalloc.h and string.h: that's
the job of system.h.
* src/options.c: Don't include stdio.h and xalloc.h for the same
reasons.

One structure for states is enough, even though theoretically
