Smells like something like Geoff did:

2005-03-24  Geoffrey Keating  <geoffk@apple.com>

	* 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.

?  Odd, he says he tested it...
