fmovd clears the current exception field in the %fsr, fsrc2 does not and therefore runs more efficiently on some cpus. * sysdeps/sparc/sparc64/memcpy.S: Use fsrc2 to move 64-bit values between float registers. * sysdeps/sparc/sparc64/memset.S: Likewise. * sysdeps/sparc/sparc64/multiarch/memcpy-niagara2.S: Likewise.
