Subject: [PATCH 1/2] y2038: hurd: Provide __clock_gettime64 function
Date: Thu, 16 Jan 2020 13:35:00 -0000 [thread overview]
Message-ID: <20200116132728.11646-1-lukma@denx.de> (raw)
For Linux glibc ports the __TIMESIZE == 64 ensures proper aliasing for
__clock_gettime64 (to __clock_gettime).
When __TIMESIZE != 64 (like ARM32, PPC) the glibc expects separate definition
of the __clock_gettime64.
The HURD port only provides __clock_gettime, so this patch adds
__clock_gettime64 as a tiny wrapper on it.
