* Fix PostRA antidependence breaker.Andrew Trick2011-02-081-3/+3
| | | | | | | | | Avoid using the same register for two def operands or and earlyclobber def and use operand. This fixes PR8986 and improves on the prior fix for rdar://problem/8959122. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125089 91177308-0d34-0410-b5e6-96231b3b80d8
