...v[0]) << "with flush, output size: " << outStr.length() << "\n"; But this always yields "with flush, output size: 0" I tried to flush the raw_string_ostream before using the string, same result. The used command line was llc -march=amdgcn -mcpu=gfx906 < module.ll Anyone see what's wrong with the code? Frank

Hi! I'm trying to figure out how to access the workgroup id from within the LLVM IR language when lowering with the AMDGPU backend. Looking at the 'llvm/include/llvm/IR/IntrinsicsAMDGPU.td' file there are intrinsics defined to access the workitem index (thread index), but this file lives in 'llvm/include':
