10353 aix31.h, aix3newas.h, aix41.h, aix43.h, beos.h,
10354 with the aim that rs6000.h is the first header
10355 included and the others override it.
10358 * x-aix41-gld: Remove.
10360 * x-aix41: Remove target-specific switches, and don't specify
10361 -Wl,-bbigtoc as we don't need it any more.
10362 * ../../configure.in: Use x-aix41 for ppc AIX 4.1 and above.
10363 Use t-aix43 for AIX 4.3 and above.
10364 * ../../configure: Regenerated.
10366 * rs6000.h (TARGET_SWITCHES): Add some initial prolog-scheduling
10367 options, that don't do anything yet.

10375 * rs6000.c: Correct comment, the `minimal' TOCs are actually
10376 one per translation unit, not one per function.
10377 (output_toc): Also do duplicate constant elimination
10378 for per-translation-unit TOCs.
10380 * rs6000.md (nonlocal_goto_receiver): Put it back as before. Add

10397 where they clearly shouldn't be. This may need to be fixed
10398 later when there is a GNU ar for AIX.
10399 * x-aix43: Don't define CLIB or AR_FOR_TARGET.
10400 Don't define BOOT_LDFLAGS as it is now not necessary.
