Hi all,
I was following the separate discussion on this list about writing
various trig functions using vector intrinsics. I googled for it. The
top few results I got were for "old" processors when SIMD intrinsics
were new. The gcc documentation (my version is 4.1.2) has a list of
intrinsics but no description, not even one line per intrinsic. As
there is need to optimize the codebase for new processors (conroe,
barcelona etc) any way, can you please point me to some real
documenatation on the subject. I would really appreciate any help.
As a related question, possibly a digression, given that these
extensions are the key to unlock full power of new processors and yet
are rather low level (we are still writing trig funcs), is there any
FLOSS library for simd math?
