Subject: enable sqrt insns for cdce3.c
Date: Wed, 10 Mar 2021 02:30:00 -0300 [thread overview]
Message-ID: <ory2evd19j.fsf@lxoliva.fsfla.org> (raw)
The test expects shrink-wrapping of the fsqrt call, but that will only
occur when there is a usable sqrt insn.
Arrange for dejagnu to add the options that enable the sqrt insn, if
one is available, and to skip the test otherwise.
H-P, this *should* obviate the mmix-specific dg-skip-if. Would it be
easy for you to confirm that this is the case and, if so, drop it?
This was regstrapped on x86_64-linux-gnu, tested with a cross to a
ppc64-vxworks7r2 configured for a cpu that doesn't have fsqrt enabled,
and I'm now also regstrapping on ppc64-linux-gnu just to be sure.
Ok to install?
