Adding -verify-machineinstrs option to PowerPC tests Currently we have a number of tests that fail with -verify-machineinstrs. To detect this cases earlier we add the option to the testcases with the exception of tests that will currently fail with this option. PR 27456 keeps track of this failures. No code review, as discussed with Hal Finkel. llvm-svn: 277624

[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. llvm-svn: 210536

[PowerPC] Swap arguments to vpkuhum/vpkuwum on little-endian In commit r213915, Bill fixed little-endian usage of vmrgh* and vmrgl* by swapping the input arguments. As it turns out, the exact same fix is also required for the vpkuhum/vpkuwum patterns. This fixes another regression in llvmpipe when vector support is enabled.

[PATCH][PPC64LE] Correct little-endian usage of vmrgh* and vmrgl*. Because the PowerPC vmrgh* and vmrgl* instructions have a built-in big-endian bias, it is necessary to swap their inputs in little-endian mode when using them to implement a vector shuffle. This was previously missed in the vector LE implementation. There was already logic to distinguish between unary and "normal" vmrg* vector shuffles, so this patch extends that logic to use a third option: "swapped" vmrg* vector shuffles that are used for little endian in place of the "normal" ones. I've updated the vec-shuffle-le.ll test to check for the expected register ordering on the generated instructions. This bug was discovered when testing the LE and ELFv2 patches for safety if they were backported to 3.4. A different vectorization decision was made in 3.4 than on mainline trunk, and that exposed the problem. I've verified this fix takes care of that issue. llvm-svn: 213915

[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.

[PATCH][PPC64LE] Correct little-endian usage of vmrgh* and vmrgl*. Because the PowerPC vmrgh* and vmrgl* instructions have a built-in big-endian bias, it is necessary to swap their inputs in little-endian mode when using them to implement a vector shuffle. This was previously missed in the vector LE implementation. There was already logic to distinguish between unary and "normal" vmrg* vector shuffles, so this patch extends that logic to use a third option: "swapped" vmrg* vector shuffles that are used for little endian in place of the "normal" ones. I've updated the vec-shuffle-le.ll test to check for the expected register ordering on the generated instructions. This bug was discovered when testing the LE and ELFv2 patches for safety if they were backported to 3.4. A different vectorization decision was made in 3.4 than on mainline trunk, and that exposed the problem. I've verified this fix takes care of that issue. llvm-svn: 213915

[PPC64LE] Fix wrong IR for vec_sld and vec_vsldoi My original LE implementation of the vsldoi instruction, with its altivec.h interfaces vec_sld and vec_vsldoi, produces incorrect shufflevector operations in the LLVM IR. Correct code is generated because the back end handles the incorrect shufflevector in a consistent manner. This patch and a companion patch for Clang correct this problem by removing the fixup from altivec.h and the corresponding fixup from the PowerPC back end. Several test cases are also modified to reflect the now-correct LLVM IR. llvm-svn: 214800

[PowerPC] Swap arguments and adjust shift count for vsldoi on little endian Commits r213915 and r214718 fix recognition of shuffle masks for vmrg* and vpku*um instructions for a little-endian target, by swapping the input arguments. The vsldoi instruction requires similar treatment, and also needs its shift count adjusted for little endian. Reviewed by Ulrich Weigand. This is a bug fix candidate for release 3.5 (and hopefully the last of those for PowerPC). llvm-svn: 214923

[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. llvm-svn: 210536
