------- Comment #1 from irar at il dot ibm dot com 2007-02-22 07:58 -------
Here is the ChangeLog entry for that patch:
2007-02-09 Richard Henderson <rth@redhat.com>
* config/i386/constraints.md (Ym): New constraint.
* config/i386/i386.md (movsi_1): Change Y2 to Yi constraints.
(movdi_1_rex64): Split sse and xmm general register moves from
memory move alternatives. Use conditional register constraints.
(movsf_1, movdf_integer): Likewise.
(zero_extendsidi2_32, zero_extendsidi2_rex64): Likewise.
(movdf_integer_rex64): New.
(pushsf_rex64): Fix output constraints.
* config/i386/sse.md (sse2_loadld): Split rm alternative, use Yi.
(sse2_stored): Likewise.
(sse2_storeq_rex64): New.
* config/i386/i386.c (x86_inter_unit_moves): Enable for not
amd and not generic.
(ix86_secondary_memory_needed): Don't bypass TARGET_INTER_UNIT_MOVES
for optimize_size. Remove SF/DFmode hack.

Could you post exact steps how to reproduce this failure?

Run
make bootstrap BOOT_CFLAGS="-O2 -g -ftree-vectorize -msse2"

------- Comment #5 from rth at gcc dot gnu dot org 2007-02-22 18:07 -------
I don't think this has anything to do with either vectorization or my patch.
I was seeing that same failure with --with-arch=pentium4 before my patch.
