Good to know. But GAS does of course support SSE2 (and more) now. What I meant was you can't use it unless the OS turns on the OSFXSR bit (and turns off EM). And FPC/DOS uses CWSDPMI, ring 3 version, so you can't do it yourself (unless you know how to workaround that ... there is supposedly a way, but it's undocumented and I dunno how).
