Actually, mmx doesn't really mean anything:
http://en.wikipedia.org/wiki/MMX
mplayer and the X server gain performance by using these extensions
(mmx, sse, sse2). One of the reasons why X is much faster in Gentoo
than in Debian. (Personal Experience, please, no flames)

Well, if they're /not/ mutually exclusive, another question that comes
up is...
If a program is compiled with sse or sse2 support on a Pentium II, will
the program run slower than it otherwise would? (Some of the programs I
have are compiled and then distributed to servers with different
CPUs--P-I
Certain program have support for either of these extentions. The
program will most likely use the best one for the job.
They can be mutually exclusive, however, if you use the CFLAG
-mfpmath=sse,387. As far as I know it, it will try to use SSE
instructions for math where possible, in detriment of

Are these flags mutually exclusive?
I know, for example, that if I have a Pentium II that the MMX flag
should apply while the sse and sse2 flags would not.
But what if I have a Pentium III or IV? Would I only use the most recent
"optimization" or do I need to add all three to take advantage of ea
