...just as time goes on, the more likely it is someone will want to do some type of optimization to accommodate lowest common denominator type machines. So I guess what I am saying is that it would be good to have at minimum: NONE MMX (lcd type machines) SSE (i.e. 3dnow ext with no OS XMM support) SSE_XMM (i.e. 3dnow ext, sse, with OS XMM support) ALTIVEC my 2p, Tom At 01:09 AM 1/15/2004, Jean-Marc Valin wrote: > > We agree on not supporting the non-FP version, however the run time flags > > need to be settable with a non FP SSE mode so that exceptions are avoided. > >I think we...

So we ran the code on a Windows XP based Atholon XP system and the xmm registers work just fine so it appears that Windows 2000 and below does not support them. We agree on not supporting the non-FP version, however the run time flags need to be settable with a non FP SSE mode so that exceptions are avoided. I thus propose a set of defines like this instead of the ones in our initial patch:
