Small testcase:
int f(double a, double b)
{
int a1 = a;
int b1 = b;
return a1+b1;
}
You can reproduce this on powerpc-darwin with -mcpu=601

------- Additional Comments From pinskia at gcc dot gnu dot org 2005-03-27 22:34 -------
This was caused by:
2005-03-25 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.
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.
