------- Comment #2 from rguenth at gcc dot gnu dot org 2006-03-08 10:18 -------
For mainline, this is a dup of 26449. For 4.1.0 I can reproduce this:
#1 0x08493eae in push_reload (in=0x4023a4b8, out=0x40241280,
inloc=0x40244a84, outloc=0x40229be0, class=NO_REGS, inmode=V4SImode,
outmode=TImode, strict_low=0, optional=0, opnum=0, type=RELOAD_OTHER)
at /space/rguenther/src/svn/gcc-4_1-branch/gcc/reload.c:1302
gcc_assert (class != NO_REGS
|| (optional != 0 && type == RELOAD_FOR_OUTPUT));
(gdb) call debug_rtx (in)
(const_vector:V4SI [
(const_int 9633 [0x25a1])
(const_int 9633 [0x25a1])
(const_int 9633 [0x25a1])
(const_int 9633 [0x25a1])
])
(gdb) call debug_rtx (out)
(reg:TI 23 xmm2)
this problem may be latent on the mainline (so I make it depend on 26449).
This is a regression in that we didn't ICE here for 4.0, but we didn't do any
vectorization there either.
So, who's the reload expert for vector stuff ;)
