on newer CPU

clang 3.1
FP EMULATION        :          594.52  :     285.28  :      65.83
gcc 4.8 branch
FP EMULATION        :             544  :     261.04  :      60.23
gcc 4.7 branch
FP EMULATION        :          520.32  :     249.67  :      57.61
gcc 4.6 branch
FP EMULATION        :          507.84  :     243.69  :      56.23

reverting of 175752 has no effect on 4.7 in case of FP EMU
