*	libstdc++: Fix semaphore to work with system_clock timeouts	Jonathan Wakely	2021-04-22	2	-4/+0
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The __cond_wait_until_impl function takes a steady_clock timeout, but then sometimes tries to compare it to a time from the system_clock, which won't compile. Additionally, that function gets called with system_clock timeouts, which also won't compile. This makes the function accept timeouts for either clock, and compare to the time from the right clock. This fixes the compilation error that was causing two tests to fail on non-futex targets, so we can revert the r12-11 change to disable them. libstdc++-v3/ChangeLog: * include/bits/atomic_timed_wait.h (__cond_wait_until_impl): Handle system_clock as well as steady_clock. * testsuite/30_threads/semaphore/try_acquire_for.cc: Re-enable. * testsuite/30_threads/semaphore/try_acquire_until.cc: Re-enable.

*	libstdc++: Fix handling of futex wake [PR 97936]	Jonathan Wakely	2020-11-25	1	-1/+0
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The __platform_wait function is supposed to wait until addr != old. The futex syscall checks the initial value and returns EAGAIN if addr != old is already true, which should cause __platform_wait to return. Instead it loops and keeps doing a futex wait, which keeps returning EAGAIN. libstdc++-v3/ChangeLog: PR libstdc++/97936 * include/bits/atomic_wait.h (__platform_wait): Return if futex sets EAGAIN. * testsuite/30_threads/latch/3.cc: Re-enable test. * testsuite/30_threads/semaphore/try_acquire_until.cc: Likewise.
