Linked #192533 and reworded to "does not yet support". It's the driver, not the front end the arch check at the top of RenderSCPOptions returns early for 32-bit Arm, so it never reaches the hasFlag call. Regarding silent passing the armv7k-apple-linux line covers that. It hits the same early return, but with an explicit flag, so it emits the argument unused warning that the test checks for. https://github.com/llvm/llvm-project/pull/209279 _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
