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

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.


i know that the current fpu/sse support of DMD isn't that good, but are
there any attemps to use SSE code insinde of std.math implementation
wouldn't give SSE better results here (beside that someone needs to implement it)?

just as a question

Not for 32-bit. Even the last AMD 32-bit processors didn't support SSE2.
For 64-bit, it makes sense, since all x86-64 processors can do SSE2. It will definitely happen for 64.
