I am attaching the "bad" rs6000.s (generated with vectorization) and "good"
rs6000.s (generated with vectorization and -fno-move-loop-invariants) using
revision 110852 (from February 2006). I looked over these a bit, bu

I am testing a patch for x86 boostrap failure. It was caused by a bug in
vectorization of strided accesses analysis, and, therefore, has nothing to do
with the bootstrap failures on ppc.

I reproduced the wrong printings on x86. It seems to be a problem in strided

I committed the patch that enables vectorization of strided accesses
(http://gcc.gnu.org/ml/gcc-patches/2006-03/msg01679.html), and now bootstrap
with vectorization fails also on x86 with the same error as in comment #3
