------- Comment #1 from rguenth at gcc dot gnu dot org 2010-06-28 09:17 -------
Confirmed. A recent regression.
#2 0x00000000009ad621 in simplify_subreg (outermode=HImode,
op=0x7ffff7facd40, innermode=QImode, byte=0)
at /space/rguenther/src/svn/trunk/gcc/simplify-rtx.c:5116
5116 gcc_assert (GET_MODE (op) == innermode
5117 || GET_MODE (op) == VOIDmode);
(gdb) call debug_rtx (op)
(reg:HI 68)
during combine.
