* Disable rematerialization in TwoAddressInstructionPass.Manman Ren2012-07-251-78/+6
| | | | | | | | | | | | It is redundant; RegisterCoalescer will do the remat if it can't eliminate the copy. Collected instruction counts before and after this. A few extra instructions are generated due to spilling but it is normal to see these kinds of changes with almost any small codegen change, according to Jakob. This also fixed rdar://11830760 where xor is expected instead of movi0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160749 91177308-0d34-0410-b5e6-96231b3b80d8

* Preserve 2-addr constraints in ConnectedVNInfoEqClasses.Jakob Stoklund Olesen2012-07-251-7/+4
| | | | | | | | | | | | | | | | | | | | When a live range splits into multiple connected components, we would arbitrarily assign <undef> uses to component 0. This is wrong when the use is tied to a def that gets assigned to a different component: %vreg69<def> = ADD8ri %vreg68<undef>, 1 The use and def must get the same virtual register. Fix this by assigning <undef> uses to the same component as the value defined by the instruction, if any: %vreg69<def> = ADD8ri %vreg69<undef>, 1 This fixes PR13402. The PR has a test case which I am not including because it is unlikely to keep exposing this behavior in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160739 91177308-0d34-0410-b5e6-96231b3b80d8
