        * config/rs6000/rs6000.md (UNSPEC constants): Add UNSPEC_STFIWX.
        (fix_truncdfsi2): Allow registers or memory as destination.
        When TARGET_PPC_GFXOPT, generate simplified pattern.
        (fix_truncdfsi2_internal): Use define_insn_and_split.
        (fix_truncdfsi2_internal_gfxopt): New.
        (fctiwz): Don't confuse register allocation by giving it no choices.
        (stfiwx): New.
        * config/rs6000/rs6000.h (EXTRA_CONSTRAINT): Add 'Z'.
        (EXTRA_MEMORY_CONSTRAINT): Likewise.
        * config/rs6000/rs6000.c (indexed_or_indirect_operand): New.
        * config/rs6000/rs6000-protos.h (indexed_or_indirect_operand): New.

There are a large number of regressions on powerpc-linux and powerpc-aix because of this change.
20000127-1.c is one of the regressions.
