_Finally I kind of modified llvm to generate assembly that can run on AMDGPU pro drivers. One problem is the performance of the code generated by llvm is about 10% slower than amdgpu's online compiler. Anything I can tune the performance up the performance of llvm?_ This is very dependent on the case you are looking at, so without a specific example or ISA comparison between the compilers there’s no guessing
