commit 8d6bb57c44557c344d56653c3380885bf1dcabd7
Author: David S. Miller <davem@davemloft.net>
Date: Wed Nov 6 13:01:36 2013 -0800
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.
