Since the VSrc_* register classes contain both VGPRs and SGPRs, copies that used be emitted by isel like this: SGPR = COPY VGPR Will now be emitted like this: VSrC = COPY VGPR This patch also adds a pass that tries to identify and fix situations where a VGPR to SGPR copy may occur. Hopefully, these changes will make it impossible for the compiler to generate illegal VGPR to SGPR copies. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187831 91177308-0d34-0410-b5e6-96231b3b80d8 |
