------- Comment #1 from pinskia at gcc dot gnu dot org 2006-11-19 20:21 -------
I think this was already fixed via:
2006-11-14 Paolo Bonzini <[EMAIL PROTECTED]>
PR rtl-optimization/29798
* fwprop.c (use_killed_between): Check that DEF_INSN dominates
TARGET_INSN before any other check.
(fwprop_init): Always calculate dominators.
(fwprop_done): Always free them.
I cannot reproduce this on the mainline as of revision 118984 (with a fix to
fwprop.c for the bootstrap failure which I am about to send off but that should
not cause any differences here).
Can you show what exact version you are using?
This is what I get:

(float:SF (mem:SI (reg/f:SI 7 sp) [0 S4 A8]))) 128 {*floatsisf2_i387}
