LLVM/CLANG: CUDA compilation fail for inline assembly code
...stargpu/download>
benchmark suite with LLVM/CLANG.
This suite has a following piece of code (more info here

):
- static __device__ uint get_smid(void) {
- uint ret;
- asm("mov.u32 %0, %smid;" : "=r"(ret) );
- return ret;
- }
The original make file has nvcc compiler with a flag -Xptxas -v. It
compiles with nvcc.
LLVM has -Xcuda-ptxas <arg>, which I believe is the comparable command for
compiling PTX code. I get fol...
