Thanks, -m32 did the trick.

I am testing a patch.

Thanks,

I can't reproduce it. Please attach vectorizer's dump
(-fdump-tree-vect-details).

Thanks,
Ira

It is caused by revision 155584:

http://gcc.gnu.org/ml/gcc-cvs/2010-01/msg00043.html

and fixed by revision 161655:

http://gcc.gnu.org/ml/gcc-cvs/2010-07/msg6.html

on trunk.

Confirmed.

#2  0x00ec5b41 in ix86_vectorize_builtin_vec_perm_ok (
vec_type=0x75a04dc8, mask=0x75a7d2a0)
at /space/rguenther/src/svn/gcc-4_5-branch/gcc/config/i386/i386.c:30144
30144 gcc_assert (vec_mask  0  vec_mask = 3);
(gdb) p vec_mask
$1 = 0

1912  if (!targetm.vectorize.builtin_vec_perm_ok (vectype,
1913 
mask_vec))
(gdb) call debug_generic_expr (mask_vec)
{ 0xfff8, 0xfff8,
0xfff8, 0xfffb,
0xfffb, 0xfffb,
0xfffe, 0xfffe }
(gdb) call debug_generic_expr (vectype)
const vector short unsigned int

I don't know why the mask elements are negative, but that's certainly
the problem with extract_vec_perm_cst which requires positive elements.

The problem is surely latent on trunk (no changes in that area).

Ira?
