[PATCH] Make SSE Run Time option. Add Win32 SSE code
...e 37) It talks about the FEATURE_SSEFP support
which you have to query for. On the Atholon XP 2400+ that we have here,
that code does not detect the presence of that when run under Windows. The
same code on a Pentium 4 detects it just fine.
Here is an article which describes the K8 (Opteron and Atholon64) as
including the XMM registers:
http://sysopt.earthweb.com/articles/k8/index2.html . All the stuff I could
google seems to indicate that XMM register support is not included in the
current Atholon XP series or below.
With any machine you are not guaranteed to get support for the XMM
register...

[PATCH] Make SSE Run Time option. Add Win32 SSE code
...to be
useless for Speex because everything fits in the L1 anyway. Now if you
really want to do something about AMD processors (mainly pre-XP
Athlons), a 3DNow! implementation would give you a great speedup
(probably even better than SSE).

Believe me, it is. I can even tell you that the floating...

[PATCH] Make SSE Run Time option. Add Win32 SSE code
Jean-Marc,
There is a big difference between SSE and SSEFP. The SSEFP means
that the CPU supports the xmm registers. All Intel chips with SSE support
do, however no current 32 bit AMD chips support the XMM registers. They
will support the SSE instructions but not those registers. You are right
about the SSE2 not being used.
The AMD Opterons are the first AMD CPU's which support
