In order to simplify the preprocessor checks for whether __atomic_wait is available, this commit does: -#if defined _GLIBCXX_HAS_GTHREADS || _GLIBCXX_HAVE_LINUX_FUTEX +#ifdef _GLIBCXX_HAVE_ATOMIC_WAIT The original was wrong anyway, as it should have used 'defined' to check _GLIBCXX_HAVE_LINUX_FUTEX (for consistency with how that's used elsewhere). The new macro is defined in <bits/atomic_wait.h> when the file is defines __atomic_wait and related facilities. All other code that depends on those features can just check the one macro. libstdc++-v3/ChangeLog: * include/bits/atomic_wait.h (_GLIBCXX_HAVE_ATOMIC_WAIT): Define. * include/bits/atomic_base.h: Check _GLIBCXX_HAVE_ATOMIC_WAIT. * include/bits/atomic_timed_wait.h: Likewise. * include/bits/semaphore_base.h: Likewise. * include/std/atomic: Likewise. * include/std/latch: Likewise. * include/std/semaphore: Likewise. |
