--- Comment #13 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Actually, lookng at the kernel, I don't see how this can happen. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/include/linux/fortify-string.h uses __FORTIFY_INLINE macro for memset, which is defined in the same file as: #define __FORTIFY_INLINE extern __always_inline __attribute__((gnu_inline)) and https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/include/linux/compiler_attributes.h defines __always_inline as #define __always_inline inline __attribute__((__always_inline__)) fnsplit pass punts on inline functions with __always_inline__ attribute, they need to be wholly inlined always.
