89cab50df1 The location tracking mechanism is precious for parse error
messages.  Nevertheless, it is enabled only when `@n' is used in
the grammar, which is a different issue (you can use it in error
message, but not in the grammar per se).  Therefore, there should
be another means to enable it.
* src/getargs.c (getargs): Support `--locations'.
(usage): Report it.
* src/getargs.h (locationsflag): Export it.
* src/lex.c (percent_table): Support `%locations'.
* src/reader.c (yylsp_needed): Remove this variable, now replaced
with `locationsflag'.
* doc/bison.texinfo: Document `--locations' and `%locations'.
Sort the options.
* tests/calc.m4: Test it.
For regularity of the names, replace each
(nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
(no_lineflag, token_tableflag, rawflag, no_parserflag): this.
In addition replace each `flag' with `_flag'.

71da9eeacc Improve the readability of the produced parsers.
* src/bison.s1: Formatting changes.
Improve the comment related to the `$' mark.
(yydefault): Don't fall through to `yyresume': `goto' there.
* src/output.c (output_parser): When the `$' is met, skip the end
of its line.
New variable, `number_of_dollar_signs', to check there's exactly
one `$' in the parser skeleton.

d7913476c4 Use the more standard files xalloc.h' and xmalloc.c' instead of
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...

prototypes.

f2acea59d9 * src/output.c (token_actions): Introduce a temporary array,
YYDEFACT, that makes it possible for this function to use
output_short_table.

d019d65507 user_toknums' is output as a short[]' in `output.c', while it is
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.

6c89f1c138 * src/output.c (output): Topological sort of the functions, in
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.

ceed8467b7 * src/output.c: Formatting changes.
* 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.
