--- Comment #8 from Alexander Monakov <amonakov at gcc dot gnu.org> --- No, -msoft-stack-reserve-local is really meant to be in bytes: it may not exceed the amount of .local memory reserved by CUDA driver (which is just 1-2 KB, unless overridden via cuCtxSetLimit, which nvptx-run.c does, but plugin-nvptx.c does not). Keep in mind that .local memory reservation is multiplied by number of active contexts, which could be in range 20000-30000 when the code was written: 128KB local memory per active thread would imply a 2.5GB allocation on the GPU.
