SSE2 Horizontal Additions.
Help!!!
I''m in the process of writing a highly optimized math engine.
I''m working on an inlined Scalar Product function, which on my comp, executes at around 0.0017 microseconds (is that good??!!).
However, i''m trying to locate the Intel intrinsic
_mm_hadd_ps
function... In the hope I can shave of some more cycles.
Where the *%$^ is it!!!???
I''ve already scanned the
xmmintrin.h
emmintrin.h
include files... But to no avail... :-((
Much appreciate if someone could help!!!
Thanks.
