Bill Schmidt pointed out that some adjustments would be needed to properly support powerpc64le (using the ELF V2 ABI). For one thing, R11 is not available as a scratch register, so we need to use R12. R12 is also available under ELF V1, so to maintain consistency, I flipped the order to make R12 the first scratch register in the array under both ABIs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@226247 91177308-0d34-0410-b5e6-96231b3b80d8
