This is currently considered experimental, but most of the more commonly used instructions should work. So far only SI has been extensively tested, CI and VI probably work too, but may be buggy. The current set of tests cases do not give complete coverage, but I think it is sufficient for an experimental assembler. See the documentation in R600Usage for more information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@234381 91177308-0d34-0410-b5e6-96231b3b80d8
