...to do better by somehow leveraging TBAA for "int"?) Here's a quick overview of how errno is implemented on different systems: - Traditional POSIX (not thread safe): extern int errno; - DragonFly libc: extern __thread int errno; - Android libc: extern volatile int* __errno(void); #define errno (*__errno()) - Darwin libc: int * __error(void); #define errno (*__error()) - musl libc: extern int *__errno_location(void); #define errno (*__errno_location()) Does anyone see any problems with making stronger (type-based) assumptions re: errno (and, t...
