llvm clang can compile opencl file into assembly. A common format is hsa. There are certain configurations in hsa assembly file, such as enable_sgpr_dispatch_ptr and enable_sgpr_queue_ptr. When I compile my opencl file, the generated assembly file has some configure on and some off. e.g. enable_sgpr_dispatch_ptr is set to 1 but enable_sgpr_queue_ptr is set to 0. Can I control those configurations when llvm compile opencl? Something like passing a command line parameter or define some env? I am also wondering if this is done through libclc.
