OpenCL lets you do things like ``` #pragma OPENCL EXTENSION <extension_name> : <behavior> ``` Which are supposed to influence the code generated, which could conceivably extend to a runtime. Kernel attributes are the canonical way to state that a kernel doesn't need something. OpenMP doesn't really expose kernels, and the OpenMP runtime is global state so it's strange. I'm generally against introducing new clang driver flags for increasingly specific behavior.
The way these are handled right now is just magic config globals we rely on LTO to fix-up, I.e. `OMPBuilder.createGlobalFlag(CGM.getLangOpts().OpenMPNoThreadState)`. Surely there's a way to inject this behavior without a new driver flag every time? https://github.com/llvm/llvm-project/pull/178914 _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
