[NVPTX] launch_bounds support?

Project Infrastructure LLVM Dev List Archives
#1

Dear all,

Is anybody working on CUDA launch bounds support?

On PTX level, attribute((launch_bounds(MAX_THREADS_PER_BLOCK, MIN_BLOCKS_PER_MP))) should be emitted into .maxntid / .minnctapersm specification.

Thanks,

Yes, this is supported through metadata. An example usage of these annotations is given in the test/CodeGen/NVPTX/annotations.ll unit test. I’ll try to remember to add this to the NVPTX documentation I’m putting together at http://llvm.org/docs/NVPTXUsage.html.

Wow, great, thanks! I will try to try it.
