commit r16-4146-g4c1d8818dee177b4f6c3adbf747873a0443d02b6 Author: Martin Uecker <[email protected]> Date: Sat Sep 13 08:37:32 2025 +0200 c: Fix regression related to DECL_NONLOCAL on aarch64 [PR121933] The recent patch r16-3747-gafa74d37e81 to detect the use of non-local context by nested functions caused regressions on aarch64, because DECL_NONLOCAL was set on labels. Fix this by setting it only to the same types of decls as before. PR target/121933 gcc/c/ChangeLog: * c-typeck.cc (mark_decl_used): Set DECL_NONLOCAL only for VAR_DECL, FUNC_DECL, PARM_DECL.
