2012-06-15Fix the encoding of the armv7m (MClass) for MSR registers other than aspr,Kevin Enderby
iaspr, espr and xpsr which also needed to have 0b10 in their mask encoding bits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158560 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-15ARM: optimization for sub+abs.Manman Ren
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

2012-06-15LSR: fix expansion of scaled reg in non-address type formulae.Andrew Trick
For non-address users, Base and Scaled registers are not specially associated to fit an address mode, so SCEVExpander should apply normal expansion rules. Otherwise we may sink computation into inner loops that have already been optimized. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158537 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-15Some optimizations done by globalopt are safe only for internal linkage, notRafael Espindola
