------- Comment #1 from kkojima at gcc dot gnu dot org 2007-03-15 13:16 -------
I've confirmed that the trunk and 4.2 compilers ice on the testcase
and 4.0 doesn't fail. So this is a 4.1/4.2/4.3 regression.
In the problematic case, sh_adjust_cost takes SET_DEST (PATTERN (dep_insn))
where dep_insn is
(insn:HI 8 7 47 2 (parallel [
(set (reg:SF 2 r2 [orig:160 num ] [160])
(mem/c/i:SF (reg/f:SI 1 r1 [162]) [2 f+0 S4 A32]))
(use (reg/v:PSI 151 ))
(clobber (scratch:SI))
]) 202 {movsf_ie} (nil)
(nil))
and calls reg_overlap_mentioned_p with it as the first argument.
We can't use SET_DEST for parallel patterns directly. Now I'm
testing the patch below on the trunk.
