If you compile your code (e.g. a plugin) without -msse

-ffast-math doesn't work?
If you compile your code with -msse and -mfpmath=sse,
you have Ardour's
protection from denormals. If the user's CPU supports it, you get there
is no significant slowdown with denormals using this mode. However CPU
support is "some later processors with SSE2", according to Intel.
Doesn't that translate to something like: Pentium 4, Pentium M, or Later.
