11801 2000-01-04 Geoff Keating <geoffk@cygnus.com>
11803 Lots of changes to rs6000.h, sysv4.h, aix.h,
11804 aix31.h, aix3newas.h, aix41.h, aix43.h, beos.h,
11805 with the aim that rs6000.h is the first header
11806 included and the others override it.
11809 * x-aix41-gld: Remove.
11811 * x-aix41: Remove target-specific switches, and don't specify
11812 -Wl,-bbigtoc as we don't need it any more.
11813 * ../../configure.in: Use x-aix41 for ppc AIX 4.1 and above.
11814 Use t-aix43 for AIX 4.3 and above.
11815 * ../../configure: Regenerated.
11817 * rs6000.h (TARGET_SWITCHES): Add some initial prolog-scheduling
11818 options, that don't do anything yet.

11826 * rs6000.c: Correct comment, the `minimal' TOCs are actually
11827 one per translation unit, not one per function.
11828 (output_toc): Also do duplicate constant elimination
11829 for per-translation-unit TOCs.
11831 * rs6000.md (nonlocal_goto_receiver): Put it back as before. Add
11832 a comment explaining _exactly_ when this pattern gets used.

11847 * t-aix43: Move AR_FOR_TARGET and CLIB here from x-aix43,
11848 where they clearly shouldn't be. This may need to be fixed
11849 later when there is a GNU ar for AIX.
11850 * x-aix43: Don't define CLIB or AR_FOR_TARGET.
11851 Don't define BOOT_LDFLAGS as it is now not necessary.
11853 1999-12-29 Geoff Keating <geoffk@cygnus.com>
11855 * rs6000.c (rs6000_build_va_list): Use 'char *' rather than 'void *'
11856 for va_list on AIX. Use unsigned_char_type_node rather than
11857 constructing our own version on svr4.
