Subject: Fix build on pre-v9 32-bit Sparc.
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e02bebc1e960eb20099738b3ecce1ac780925729;p=thirdparty%2Fglibc.git

Fix build on pre-v9 32-bit Sparc.

We cannot use fnegd in this code, as fnegd was added in v9.
Only fnegs exists in v8 and earlier.

	[BZ #15985]
	* sysdeps/sparc/sparc32/fpu/s_fdim.S (__fdim): Do not use fnegd
	on pre-v9 cpus, use a fnegs+fmovs sequence instead.

(cherry picked from commit 2216e48645dbd297cdc0f4050fdfc0b52e2a4ab8)
