Tim Northover aae0fa998a Teach ReMaterialization to be more cunning about subregisters ... This allows rematerialization during register coalescing to handle more cases involving operations like SUBREG_TO_REG which might need to be rematerialized using sub-register indices. For example, code like: v1(GPR64):sub_32 = MOVZ something v2(GPR64) = COPY v1(GPR64) should be convertable to: v2(GPR64):sub_32 = MOVZ something but previously we just gave up in places like this git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182872 91177308-0d34-0410-b5e6-96231b3b80d8		2013-05-29 19:32:06 +00:00
