I'll fix the file contents in the next commit. This pass is currently expanding the COPY and SUBREG_TO_REG pseudos. I am going to add a hook so targets can expand more pseudo-instructions after register allocation. Many targets have pseudo-instructions that assist the register allocator. They can be expanded after register allocation, before PEI and PostRA scheduling. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140469 91177308-0d34-0410-b5e6-96231b3b80d8
