Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
difficult and introduced a lot of core dump. It turns out that
Bison used an implementation of `xmalloc' based on `calloc', and
at various places it does depend upon the initialization to 0. I
have not tried to isolate the pertinent places, and all the former
calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
someone should address this issue.
* src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
* lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
files.
Adjust dependencies.
* src/warshall.h: New file.
Propagate.
(first_reduction): Move their exportation from here...
* src/LR0.h: to here.
Adjust dependencies.
* src/getargs.c (statisticsflag): New variable.
Add support for `--statistics'.
Adjust dependencies.
Remove a lot of now useless `extern' statements in most files.
Propagate its use.
* src/print.c: Formatting and ordering changes.
(verbose, terse): Replace with...
(print_results): this new function.
Adjust dependencies.
defined as a `int[]' in `reader.c'. For consistency with the
other output tables, `user_toknums' is now defined as a table of
shorts.
* src/reader.c (user_toknums): Be a short table instead of an int
table.
Adjust dependencies.
Factor the short table outputs.
* src/output.c (output_short_table): New function.
* src/output.c (output_gram, output_stos, output_rule_data)
(output_base, output_table, output_check): Use it.
order to get rid of the `static' prototypes.
No longer use `register'.
* src/output.h: New file.
Propagate its inclusion in files explicitly prototyping functions
from output.c.
inclusion.
Don't define PARAMS.
* src/system.h: Define PARAMS.
Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
purpose of config.h. system.h must not try to fix wrong
definitions in config.h.
* tests/calc.m4 (_AT_DATA_CALC_Y, AT_DATA_CALC_Y, _AT_CHECK_CALC)
(AT_CHECK_CALC): New macros.
Use these macros to test bison with options `', `--raw',
`--debug', `--yacc', `--yacc --debug'.
* src/machine.h: Remove, leaving its contents in...
* src/system.h: here.
Include stdio.h.
Adjust all dependencies on stdio.h and machine.h.
* src/getargs.h: New file.
Let all `extern' declarations about getargs.c be replaced with
inclusion of `getargs.h'.
* src/Makefile.am (noinst_HEADERS): Adjust.
* tests/calc.m4 (yyin): Be initialized in main, not on the global
scope.
(yyerror): Returns void, not int.
* doc/bison.texinfo: Formatting changes.
* src/bison.s1 (yyparse): Condition the code using `yytname' which
is defined only when YYDEBUG is.
* m4/atconfig.m4 (AT_CONFIG): Adjust to Autoconf 2.13.
* src/files.c (tryopen, tryclose): Formatting changes.
Move to the top and be static.
* src/reader.c (read_signed_integer): Likewise.
* tests/calc.m4: New file.
* Makefile.am, suite.m4: Adjust.
* m4/atconfig.m4: Set BISON_SIMPLE and BISON_HAIRY.
* m4/m4.m4, m4/atconfig.m4: New files.
* m4/Makefile.am (EXTRA_DIST): Adjust.
* tests/suite.m4, tests/Makefile.am, tests/atgeneral.m4: New
files.
* src/getargs.c: Display a more standard --version message.
* src/reader.c (reader): Formatting changes.
No longer depend upon VERSION_STRING.
* configure.in: No longer use `dnl'.
Set up the test suite and the new directory `tests/.
(VERSION_STRING): Remove.
`copy_comment', but outputs into two FILE *.
(copy_comment): Use it.
(parse_union_decl): Use it.
(get_type, parse_start_decl): Use the same `invalid' message.
(parse_start_decl, parse_union_decl): Use the same `multiple'
message.
(parse_union_decl, copy_guard, copy_action): Use the same
`unmatched' message.
* m4/Makefile.am (EXTRA_DIST): Add `warning.m4'.
