| * | X86 vector element shift-by-immediate instructions take i8 immediates. Make | Lang Hames | 2013-10-21 |
| | | | | | | | | | | | | | | | | | the instruction defenitions and ISEL reflect this. Prior to this patch these instructions took an i32i8imm, and the high bits were dropped during encoding. This led to incorrect behavior for shifts by immediates higher than 255. This patch fixes that issue by detecting large immediate shifts and returning constant zero (for logical shifts) or capping the shift amount at an encodable value (for arithmetic shifts).

| * | Convert CodeGen/*/*.ll tests to use the new CHECK-LABEL for easier ↵ | Stephen Lin | 2013-07-13 |
| | | | | | | | | | | | | debugging. No functionality change and all tests pass after conversion. This was done with the following sed invocation to catch label lines demarking function boundaries: sed -i '' "s/^;\( *\)\([A-Z0-9_]*\):\( *\)test\([A-Za-z0-9_-]*\):\( *\)$/;\1\2-LABEL:\3test\4:\5/g" test/CodeGen/*/*.ll which was written conservatively to avoid false positives rather than false negatives. I scanned through all the changes and everything looks correct. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186258 91177308-0d34-0410-b5e6-96231b3b80d8 | ||
