symbol is kept, only the line of the first occurrence is kept too.
* src/symtab.h, src/symtab.c (bucket): Remove the line member.
* src/reader.c (rline_allocated): Remove, unused.
(symbol_list): Have a `line' member.
(symbol_list_new): New.
(readgram): Use it.
* src/print.c (print_grammar): Output the rule line numbers.
* tests/regression.at (Solved SR Conflicts)
(Unresolved SR Conflicts): Adjust.
Reported by Hans Aberg.
* src/closure.c: Include `reader.h' to get `tags', needed by the
trace code.
Rename the conditional DEBUG as TRACE.
Output consistently TRACEs to stderr, not stdout.
* src/derives.c: Likewise.
* src/reduce.c: (inaccessable_symbols): Using if is better style
than goto.
Use `#if TRACE' instead of `#if 0' for tracing code.
handling of VCG syntax, in particular: use quotearg.
* src/print_graph.c: Don't.
(print_actions): Don't output the actions as part of the nodes,
since that's the job of the edges.
(print_state): Don't output by hand: fill the node description,
and ask for its output.
(state_table): Be a state_t * instead of a core **.
(accessing_symbol): Remove, part of state_t.
* src/lalr.c: Adjust.
(set_accessing_symbol): Merge into...
(set_state_table): this.
* src/print_graph.c, src/conflicts.c: Adjust.
Revert a previous patch: these are really const.
* src/conflicts.c (conflict_report): Additional useless pair of
braces to pacify GCC's warnings for `if () if () {} else {}'.
* src/lex.c (parse_percent_token): Replace equal_offset with
arg_offset.
arg is const.
Be sure to strdup `arg' when used, since there is no reason for
token_buffer not to change.
* config/config.guess, config/config.sub, po/*.po: Update.
* src/system.h (ngettext): Now that we use ngettext, be sure to
provide a default definition when NLS are not used.
* src/conflicts.c (expected_conflicts): Set to -1.
(conflict_report): Use ngettext.
(conflicts_print): Check %expect and make its violation an error.
* doc/bison.texinfo (Expect Decl): Adjust.
* configure.in (AM_GNU_GETTEXT): Ask for ngettext.
* tests/regression.at (%expect not enough, %expect right)
(%expect too much): New.
(reduce_output): This.
Output to OUT, passed as argument, instead of output_obstack.
(dump_grammar): Likewise.
(reduce_free): New.
Also free V1.
(reduce_grammar): No longer call reduce_output, since...
* src/print.c (print_results): do it.
* src/main.c (main): Call reduce_free;
with yyltype/YYLTYPE. This allows inclusion of the generated
header within the parser if the compiler, such as GGC, accepts
multiple equivalent #defines.
able to understand that `--out' is OK: the two racing long options
are aliases.
(usage): Adjust.
* src/lex.h (tok_setopt): Remove, replaced with...
(tok_intopt, tok_stropt): these new guys.
* src/lex.c (getopt.h): Not needed.
(token_buffer, unlexed_token_buffer): Not const.
(percent_table): Promote `-' over `_' in directive names.
Active `%name-prefix', `file-prefix', and `output'.
(parse_percent_token): Accept possible arguments to directives.
Promote `-' over `_' in directive names.
* doc/bison.texinfo (Decl Summary): Split the list into
`directives for grammars' and `directives for bison'.
Sort'em.
Add description of `%name-prefix', `file-prefix', and `output'.
Promote `-' over `_' in directive names.
(Bison Options): s/%locactions/%locations/. Nice Freudian slip.
Simplify the description of `--name-prefix'.
Promote `-' over `_' in directive names.
Promote `--output' over `--output-file'.
Fix the description of `--defines'.
* tests/output.at: Exercise %file-prefix and %output.
* src/symtab.c (bucket_new): Init user_token_number to SUNDEF to
stand for `uninitialized', instead of 0.
* src/reader.c (packsymbols, parse_thong_decl): Adjust.
* src/lex.c (lex): Adjust.
* tests/calc.at (_AT_DATA_CALC_Y): Declare a token for EOF.
Number it 0.
Let yylex return it instead of a plain 0.
