Hi,
this is patch I ended up comitting after some furhter testing. The difference
to initial
version is that it now eanbles SSE math with -ffast-math too and it does so
outside the
ugly target macro.
Bootstrapped/regtested x86_64-linux, tested with -m32

Hi,
this patch makes -Ofast to also imply -mfpmath=sse. It is important win on
SPECfP (2000 and 2006). Even though for exmaple the following
float a(float b)
{
return b+10;
}
results in somewhat ridiculous
a:
.LFB0:
.cfi_startproc
subl$4, %esp
.cfi_def_cfa_offset
