llvm-6502/test/CodeGen/PowerPC/vaddsplat.ll
Bill Schmidt abc402886e Additional fixes for bug 15155.
This handles the cases where the 6-bit splat element is odd, converting
to a three-instruction sequence to add or subtract two splats.  With this
fix, the XFAIL in test/CodeGen/PowerPC/vec_constants.ll is removed.
