Long before that, we relied on the API stability and already have some runtime calls marked as deprecated. Especially taking into account, that libomp can be built separately. ================ Comment at: clang/lib/CodeGen/CGOpenMPRuntimeNVPTX.cpp:42 - /// *outlined_function, int16_t - /// IsOMPRuntimeInitialized); OMPRTL_NVPTX__kmpc_kernel_prepare_parallel, ---------------- JonChesterfield wrote: > ABataev wrote: > > I think, instead the optimizer can try to detect if the runtime library is > > used by the kernel and switch this flag to `0` if no runtime calls are used > > in the kernel.
