Why doesn't gcc convert strncmp to __builtin_strcmp?
It does. In fact, it first converts strncmp to __builtin_strncmp, then
optimizes it to __builtin_strcmp. Finally, __bultin_strcmp is expanded
to a call to strcmp.
So either the static inline strcmp routine has to be dropped from
arch/m68k/include/asm/string.h (along with #define __HAVE_ARCH_STRCMP), or
else a static inline strncmp has to be added (along with #define
__HAVE_ARCH_STRNCMP)?
