Bill Schmidt b02d95cb66 [PPC64LE] Recognize shufflevector patterns for little endian ... Various masks on shufflevector instructions are recognizable as specific PowerPC instructions (vector pack, vector merge, etc.). There is existing code in PPCISelLowering.cpp to recognize the correct patterns for big endian code. The masks for these instructions are different for little endian code due to the big-endian numbering employed by these instructions. This patch adds the recognition code for little endian. I've added a new test case test/CodeGen/PowerPC/vec_shuffle_le.ll for this. The existing recognizer test (vec_shuffle.ll) is unnecessarily verbose and difficult to read, so I felt it was better to add a new test rather than modify the old one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210536 91177308-0d34-0410-b5e6-96231b3b80d8		2014-06-10 14:35:01 +00:00
