Subject: [PATCH 42/52] libsupport: Add 64 bit time_t support for time functions
Date: Fri, 5 Mar 2021 17:15:08 -0300 [thread overview]
Message-ID: <20210305201518.798584-43-adhemerval.zanella@linaro.org> (raw)
In-Reply-To: <20210305201518.798584-1-adhemerval.zanella@linaro.org>
The patch adds redirections for xclock_gettime, xclock_settime,
timespec_add, timespec_sub, test_timespec_before_impl,
test_timespec_equal_or_after_impl, support_timespec_ns,
support_timespec_normalize, and support_timespec_check_in_range when
_TIME_BITS=64 is defined.
