If the APX relocation types are emitted in MC, they cannot be recognized by old version of linkers. It leads to APX features unavailable on existing Linux OSes with old version of linkers. `--no-relax` just disables the GOT optimization in linker, and it cannot resolve the link error of unsupported relocation type as mentioned above. https://github.com/llvm/llvm-project/pull/136660 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
