What about making a test case that exerts great pressure on the register allocator to verify that `$ra` does not get accidentally handed out? Or if that's too fragile, if it's possible, make a variable pinned to `$ra` or `$zero` then pass it to the inline asm block with the newly added `q` constraint, to ensure a new temp gets allocated. https://github.com/llvm/llvm-project/pull/141037 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
