2000-01-04 Geoff Keating <geoffk@cygnus.com>
Lots of changes to rs6000.h, sysv4.h, aix.h,
aix31.h, aix3newas.h, aix41.h, aix43.h, beos.h,
with the aim that rs6000.h is the first header
included and the others override it.
* aix.h: New file.
* x-aix41-gld: Remove.
* x-aix43: Remove.
* x-aix41: Remove target-specific switches, and don't specify
-Wl,-bbigtoc as we don't need it any more.
* ../../configure.in: Use x-aix41 for ppc AIX 4.1 and above.
Use t-aix43 for AIX 4.3 and above.
* ../../configure: Regenerated.
* rs6000.h (TARGET_SWITCHES): Add some initial prolog-scheduling
options, that don't do anything yet.
(MASK_SCHED_PROLOG): New macro.
(MASK_SCHED_EPILOG): New macro.
(TARGET_SCHED_PROLOG): New macro.
(TARGET_SCHED_EPILOG): New macro.
2000-01-04 Geoff Keating <geoffk@cygnus.com>
* rs6000.c: Correct comment, the `minimal' TOCs are actually
one per translation unit, not one per function.
(output_toc): Also do duplicate constant elimination
for per-translation-unit TOCs.
* rs6000.md (nonlocal_goto_receiver): Put it back as before. Add
a comment explaining _exactly_ when this pattern gets used.
(builtin_setjmp_receiver): New pattern for better clarity.
(init_v4_pic): Move it into a section dealing with TOC registers.
1999-12-30 Geoff Keating <geoffk@cygnus.com>

a single file.
(rs6000_add_gc_roots): Add the hash table as a GC root.
* t-aix43: Move AR_FOR_TARGET and CLIB here from x-aix43,
where they clearly shouldn't be. This may need to be fixed
later when there is a GNU ar for AIX.
* x-aix43: Don't define CLIB or AR_FOR_TARGET.
Don't define BOOT_LDFLAGS as it is now not necessary.
1999-12-29 Geoff Keating <geoffk@cygnus.com>
* rs6000.c (rs6000_build_va_list): Use 'char *' rather than 'void *'

since patently it's not.
