commit r16-9689-g26d59a83fc6e54290b627ea636c6b65bd63f43b1 Author: Christophe Lyon <[email protected]> Date: Fri Sep 18 15:58:02 2026 +0200 Fix check for working assembler --gdwarf-4 option The code fragment used to check for --gdwarf-4 option with the APP marker ends with a hard-coded 'ret' instruction, which is not supported by all architectures (e.g. arm). Replace it with $insn. gcc/ChangeLog: * configure.ac: Replace 'ret' with '$insn'. * configure: Regenerate.
