From f9205f1d470ed1a214b841b6d2fd60fea14954cb Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Wed, 6 Sep 2017 08:43:26 +0200 Subject: [PATCH] Let RTEMS provide clock() Newlib uses _times_r() in clock(). The problem is that the _times_r() clock frequency is defined by sysconf(_SC_CLK_TCK). The clock frequency of clock() is the constant CLOCKS_PER_SEC. FreeBSD uses getrusage() for clock(). Since RTEMS has only one process, the implementation can be simplified.
