Relax expressions and add explicit triplets -linux and -win32. On @foobar(double %d, double* %x), AMD64: (%xmm0, %rdi) Win64: (%xmm0, %rdx) (not %rcx!) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126211 91177308-0d34-0410-b5e6-96231b3b80d8 2011-02-22 07:21:17 +00:00			`; RUN: llc -mtriple=x86_64-linux < %s \| FileCheck %s`

Fix PR9127 by reversing the operands even if they have more then one use. Reversing the operands allows us to fold, but doesn't force us to. Also, at this point the DAG is still being optimized, so the check for hasOneUse is not very precise. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124773 91177308-0d34-0410-b5e6-96231b3b80d8 2011-02-03 03:58:05 +00:00
