 Preprocessed source code attached. Flags -ftree-vectorize -Os -mno-sse
 required.

I don't see this with gcc 4.3 20070604.  Do you still get this failure?

Hard to say.

Recent versions of gcc 4.3 fail to compile recent
linux kernels for different reasons ;-|

On the trunk with -Os -ftree-vectorize -m64 -maltivec, I get:
t.c: In function â#128;#152;fill_table_dc00_d800â#128;#153;:
t.c:6: internal compiler error: in vect_transform_loop, at
tree-vect-transform.c:5263
Please submit a full bug report,
with preprocessed source if appropriate.

I think this is my fault.
Reduced testcase for powerpc64-linux-gnu:
struct pwc_dec23_private
{
  unsigned int table_dc00[256];
};
void fill_table_dc00_d800(struct pwc_dec23_private *pdec)
{
 int i;
 unsigned int offset1 = (1UL  (15 - 1));
 for (i=0; i256; i++) {
  pdec-table_dc00[i] = offset1  ~((1UL  (15 - 1)));
  offset1 += 0x7bc4;
 }
}


We get:
  D.1689_81 = BIT_FIELD_REF {63368}, 32, 0;
