+
+ Portability fixes for bitsets; this also avoids several GCC
+ warnings.
+
+ * lib/abitset.c: Include <stddef.h>, for offsetof.
+ * lib/lbitset.c: Likewise.
+
+ * lib/abitset.c (abitset_bytes): Return a size that is aligned
+ properly for vectors of objects. Do not assume that adding a
+ header size to a multiple of a word size yields a value that is
+ properly aligned for the whole union.
+ * lib/bitsetv.c (bitsetv_alloc): Likewise.
+
+ * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
+ unique names for structures.

+ abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
+ abitset_or_and_cmp, abitset_copy): Supply prototype decls,
+ to improve the type-checking that GCC can do.
+ * lib/bitset.c (bitset_op4_cmp): Likewise.

+ for enum_bitset_type.
+ * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
+ * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
+
+ Do not use "struct bitset_struct" to mean different things in
+ different modules. Not only is this confusing, it violates
+ the C Standard, which requires that structure types in different
+ modules must be compatible if one is to be passed to the other.
+ * lib/bbitset.h (bitset): Now points to a union, not to a struct.
+ All instances of "struct bitset_struct *" replaced with "bitset".

+
+2002-10-06 Paul Eggert <eggert@twinsun.com>
+
+ * lib/bitset.h (bitset_reset): Do not assume that bitset_word is

+ which was inadvertently undone by the 2002-09-30 patch.

+ the same width as int.
+
+2002-10-04 Paul Eggert <eggert@twinsun.com>
+
+ Version 1.50.
+
+ * configure.ac (AC_INIT), NEWS: Increment version number.
+
+ * doc/bison.texinfo: Minor spelling, grammar, and white space
+ fixes.
+ (Symbols): Mention that any negative value returned from yylex
+ signifies end-of-input. Warn about negative chars. Mention
+ the portable Standard C character set.
+
+ The GNU coding standard says CFLAGS and YFLAGS are reserved
+ for the installer to set.
+ * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
+ * src/Makefile.am (AM_CFLAGS): Likewise.

+
+2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
+

+
+ * lib/bbitset.h (BITSET_BINDEX_MAX, BITSET_WINDEX_MAX,

+
+ * lib/bitset.c (bitset_next, bitset_prev, bitset_first,

+ Handle locations.
+ * src/scan-skel.l: Adjust to these changes.
+ * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)

+ * src/scan-skel.l: Adjust.
+
+2001-12-30 Akim Demaille <akim@epita.fr>
+
+ * src/system.h: We don't need nor want bcopy.
+ Throw away MS-DOS crap: we don't need getpid.
+ * configure.in: We don't need strndup. It was even causing
+ problems: because Flex includes the headers *before* us,
+ _GNU_SOURCE is not defined by config.h, and therefore strndup was
+ not visible.
+ * lib/xstrndup.c: New.
+ * src/scan-skel.l: Use it.
+ Be sure to initialize yylval.muscle member when scanning a MUSCLE.
+ * src/parse-skel.y: Use %directives instead of #defines.
+
+2001-12-30 Akim Demaille <akim@epita.fr>

+ * src/parse-skel.y: Add the license notice.
+ Include output.h and skeleton.h.
+ (process_skeleton): Returns void, and takes a single parameter.
+ * src/scan-skel.l: Add the license notice.
+ Include skeleton.h.
+ Don't use %option yylineno: it seems that then Flex imagines
+ REJECT has been used, and therefore it won't reallocate its
+ buffers (which makes no other sense to me than a bug). It results
+ in warnings for `unused: yy_flex_realloc'.

+ names.
+
+ * src/files.h (strsuffix, stringappend): Add declarations.

+ %name-prefix is broken.
+
+ * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
+ Adjust all dependencies.
+ * tests/headers.at (export YYLTYPE): Strengthen this test: use

+ * src/reader.c (symbols_save): Remove.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+

+ * tests/regression.at (%union and C comments): Remove.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * tests/regression.at (Web2c Actions): Blindly move the actual

+ 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).
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/reader.c (readgram): Don't add the rule 0 if there were no
+ rules read. In other words, add it _after_ having performed

+ 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

+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/reader.c (readgram): Bind the initial rule's lineno to that

+ * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
+ (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.

+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',

+
+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

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

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

+ Use it to quote the TAGS outputs.
+ * src/print_graph.c (print_state): Now errors are in red, and

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

+ (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
+ appropriate skeleton which requires actions and guards is now
+ required.
+ * src/main.c (main): Adjust.
+ * tests/semantic.at: New.
+ * tests/regression.at: Use `input.y' as input file name.

+2001-12-27 Akim Demaille <akim@epita.fr>
+
+ All the hacks using a final pseudo state are now useless.

+ (resolve_sr_conflict, set_conflicts, solve_conflicts)
+ (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

+
+ * src/output.c (prepare): Drop the muscle `ntbase' which

+ Use YYNTOKENS only, which is documented, but not YYNTBASE, which
+ is an undocumented synonym.
+
+2001-12-22 Akim Demaille <akim@epita.fr>
+
+ * src/output.c (output_table_data): Change the prototype to use

+ Reported by Wayne Green.
+
+2001-12-22 Akim Demaille <akim@epita.fr>
+
+ Some actions of web2c.y are improperly triggered.

+
+ Some host fail on `assert (!"foo")', which expands to
+ ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
+ Reported by Nelson Beebee.
+
+ * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
+ `#define it_succeeded 0' and `assert (it_succeeded)'.
+
+2001-12-17 Marc Autret <autret_m@epita.fr>
+
+ * src/bison.simple: Don't hard code the skeleton line and filename.
+ * src/output.c (output_parser): Rename 'line' as 'output_line'.
+ New line counter 'skeleton_line' (skeleton-line muscle).
+
+2001-12-17 Paul Eggert <eggert@twinsun.com>
+
+ * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
+ YYDEBUG must be defined to a nonzero value.
+
+ * src/bison.simple (yytname): Do not assume that the user defines
+ YYDEBUG to a properly parenthesized expression.
+
+2001-12-17 Akim Demaille <akim@epita.fr>
+

+ Adjust all users.
+ * src/lalr.h (nlookaheads): Remove this orphan declaration.
+ * src/lalr.c (initialize_lookaheads): Set nlookaheads for each

+2001-12-17 Akim Demaille <akim@epita.fr>
+
+ * src/files.h, src/files.c (open_files, close_files): Remove.
+ * src/main.c (main): Don't open/close files, nor invoke lex_free,
+ let...

+
+2001-12-17 Akim Demaille <akim@epita.fr>
+
+ * src/conflicts.c (print_reductions): Formatting changes.

+2001-12-17 Akim Demaille <akim@epita.fr>
+

+ (flush_reduce): New.
+ (resolve_sr_conflict): Adjust.
+
+2001-12-17 Akim Demaille <akim@epita.fr>
+
+ * src/output.c (output_obstack): Be static and rename as...
+ (format_obstack): this, to avoid any confusion with files.c's
+ output_obstack.
+ * src/reader.h (muscle_obstack): Move to...
+ * src/output.h: here, since it's defined in output.c.
+
+2001-12-17 Akim Demaille <akim@epita.fr>
+
+ * src/output.c (action_row, save_column, default_goto)
+ (sort_actions, matching_state, pack_vector): Better variable
+ locality.
+
+2001-12-17 Akim Demaille <akim@epita.fr>
+
+ * src/output.c: Various formatting changes.
+
+2001-12-17 Akim Demaille <akim@epita.fr>

+
+2001-12-16 Marc Autret <autret_m@epita.fr>
+
+ * 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

+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
+ 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...
+ (copy_comment): this.
+
+2001-12-15 Akim Demaille <akim@epita.fr>
+
+ * src/lex.c, src/lex.h (xgetc): No longer static.
+ * src/reader.c (parse_union_decl): Revamp.
+
+2001-12-15 Akim Demaille <akim@epita.fr>
+
+ 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.
+
+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.
+
+2001-12-13 Akim Demaille <akim@epita.fr>
+
+ * 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.
+
+2001-12-12 Akim Demaille <akim@epita.fr>
+
+ 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
+ $(top_srcdir).
+
+2001-12-11 Marc Autret <autret_m@epita.fr>
+
+ * src/output.c (output_parser): Remove useless muscle.
+
+2001-12-11 Marc Autret <autret_m@epita.fr>
+
+ * src/bison.simple: Remove #line just before %%epilogue. It
+ is now handled in ...
+ * 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/reader.c (symbols_output): Clean up.
+ * src/output.c (output_gram, output): Clean up.
