From 0d563783490bf5b2d7d52cab205760fdff5d5650 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Thu, 24 Oct 2019 17:52:30 +0000 Subject: Use clock_gettime to implement time. Change the default implementation of time to call clock_gettime, to align with new Linux ports that are expected to only implement __NR_clock_gettime. Arch-specific implementation that either call the time vDSO or route to gettimeofday vDSO are not removed. Also for Linux, CLOCK_REALTIME_COARSE is used instead of generic CLOCK_REALTIME clockid. This takes less CPU time and its behavior better matches what the current glibc does. Checked on x86_64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu, powerpc64-linux-gnu, powerpc-linux-gnu, and aarch64-linux-gnu.
