Note that SSE is less precise than x87.
hello all,
i've read that on newer architectures
SSE code should be prefered over x87 - because of speed
and i saw masses of SSE code in the math stuff of microsoft and intel
compiler generated code
i know that the current fpu/sse support of DMD isn't that good, but are
there any attemps to

At the present time, SSE and x87 are the same speed in most cases
Don:
At the present time, SSE and x87 are the same speed in most cases (most
operations take just one cycle) -- except of course that you can do two
or four operations at once with SSE.
SSE-something also allow some other operations, sqrt, etc. Even with GCC I've
seen some performance
