Subject: [Bug fortran/28484] F2003: system_clock with real-type count_rate does not compile
Date: Sat, 19 Dec 2009 10:50:00 -0000	[thread overview]
Message-ID: <20091219105011.1586.qmail@sourceware.org> (raw)
In-Reply-To: <bug-28484-1719@http.gcc.gnu.org/bugzilla/>



------- Comment #12 from jb at gcc dot gnu dot org  2009-12-19 10:50 -------
Since the actual implementation of system_clock has no use for non-integer
count rates, this should be implemented by creating an integer temporary in the
frontend and then calling the existing functions.

Also, note that as of r155359 the integer(8) version of system_clock now
provides microsecond resolution. In the future, this could be improved further
by switching to using clock_gettime(CLOCK_MONOTONIC,...) which in addition to
providing better resolution also gives a monotonic clock instead of a realtime
clock that gettimeofday() gives.
