------------------------------------------------------------------------ r214679 | chandlerc | 2014-08-03 17:54:28 -0700 (Sun, 03 Aug 2014) | 10 lines [x86] Fix the test case added in r214670 and tweaked in r214674 further. Fundamentally, there isn't a really portable way to test the constant pool contents. Instead, pin this test to the bare-metal triple. This also makes it a 64-bit triple which allows us to only match a single constant pool rather than two. It can also just hard code the '.' prefix as the format should be stable now that it has a fixed triple. Finally, I've switched it to use CHECK-NEXT to be more precise in the instruction sequence expected and to use variables rather than hard coding decisions by the register allocator. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_35@215430 91177308-0d34-0410-b5e6-96231b3b80d8
