[PATCH] Dynamic E3DNow!/SSE2 port mixing support

Jussi Laako
Hi,

This is just a rather quick copy-and-paste patch from my libdsp
libraries to add support for dynamic asm code selection and E3DNow!/SSE2
port buffer mixing code. E3DN version should be pretty fast and SSE2
version should be at least equally fast compared to the C version. I
will improve the SSE version shortly.

Patch attached. Comments welcome... :)


Best regards,

Oh, and answer to "why?"; to get rid of need for architecture specific
compiler flags like "-mfpmath=sse". So that the same binary would be
able to run on all relevant subarchitectures and still have near-maximum
performance. This makes it easier to distribute binary packages like
RPMs.
