[llvm-commits] [PATCH][X86] Lower vector sdiv x, pow2 efficiently

[Rackover, Zvi]

The patch located at http://llvm.org/bugs/attachment.cgi?id=9832&action=diff implements an efficient lowering of vector sdiv when the divisor is a splatted power of two constant, as described in bug 14848. The lowered sequence is based on the existing sequence the target-independent DAG Combiner creates for the scalar case.

Please review this patch and apply if it is ok.

Thanks, Zvi
