This sounds like the most sensible and "correct" proposal so far. If one wants to reuse the local space allocation overhead across multiple WGs executing in the same thread, one would just need to find all the allocas to the local AS and convert them, e.g., to function arguments that are allocated by the WG launcher only once. And when creating a "multi-WI WG function", ensure the local allocas are shared across the WIs. It sounds like a working and robust approach to me, although, of course, it requires the LLVM IR update for the alloca instruction. I have no idea how drastic update it would be. -- --Pekka ------------------------------------------------------------------------------ How fast is your code? 3 out of 4 devs don\\\'t know how their code performs in production.
