Test gcc.dg/vect/costmodel/ppc/costmodel-slp-12.c was added in GCC 4.3.0 and
continues to pass on the branch. On mainline it started failing the scans of
the vectorization dumps with r138815:
2008-08-06 Victor Kaplansky <[EMAIL PROTECTED]>
Ira Rosen <[EMAIL PROTECTED]>
* tree-vect-transform.c (vect_model_simple_cost): Return
immediately if stmt is pure SLP.
(vect_model_store_cost): Ditto.
(vect_model_load_cost): Ditto.
(vectorizable_store): Remove PURE_SLP check before call
to vect_model_store_cost.
(vect_model_store_cost): When checking whether stmt describe
strided access, add a check that it is not slp_node.
The testresult archives show that it fails on powerpc* for linux, aix, darwin,
and eabisim. for powerpc64-linux it fails with both -m32 and -m64.
