The trick is not to define the _vi versions of instructions, which has these consequences: - code generation will always fail if a pseudo cannot be lowered (very useful to catch bugs where an unsupported instruction somehow makes it to the printer) - ability to query if a pseudo can be lowered, which is done in commuteOpcode to prevent REV from commuting to non-REV on VI Tested-by: Michel Dänzer <michel.daenzer@amd.com> ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_36@235317 91177308-0d34-0410-b5e6-96231b3b80d8
