Chris Lattner cef896e50c When building a VVECTOR_SHUFFLE node from extract_element operations, make ... sure to build it as SHUFFLE(X, undef, mask), not SHUFFLE(X, X, mask). The later is not canonical form, and prevents the PPC splat pattern from matching. For a particular splat, we go from generating this: li r10, lo16(LCPI1_0) lis r11, ha16(LCPI1_0) lvx v3, r11, r10 vperm v3, v2, v2, v3 to generating: vspltw v3, v2, 3 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27236 91177308-0d34-0410-b5e6-96231b3b80d8		2006-03-28 22:19:47 +00:00
