Subject: [PATCH v3 11/12] selftests/nolibc: add new gettimeofday test cases
Date: Sat, 3 Jun 2023 16:16:07 +0800 [thread overview]
Message-ID: <68dace9e2532316ff454894697ecfd99e419a523.1685777982.git.falcon@tinylab.org> (raw)
In-Reply-To: <cover.1685777982.git.falcon@tinylab.org>
These 2 test cases are added to cover the normal using scenes of
gettimeofday().
They have been used to trigger and fix up such issue with nolibc:
nolibc-test.c:(.text.gettimeofday+0x54): undefined reference to `__aeabi_ldivmod'
This issue happens while there is no "unsigned int" conversion in the
coming new clock_gettime / clock_gettime64 syscall path of
gettimeofday():
tv->tv_usec = ts.tv_nsec / 1000;
