* ARM: optimization for sub+abs.Manman Ren2012-06-151-1/+19
| | | | | | | | | | | | | | | | This patch will optimize abs(x-y) FROM sub, movs, rsbmi TO subs, rsbmi For abs, we will use cmp instead of movs. This is necessary because we already have an existing peephole pass which optimizes away cmp following sub. rdar: 11633193 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158551 91177308-0d34-0410-b5e6-96231b3b80d8
