The following are directly supported:

a[] = b[] + c[]
a[] = b[] - c[]
a[] = b[] + value
a[] += value
a[] += b[]
a[] = b[] - value
a[] = value - b[]
a[] -= value
a[] -= b[]
a[] = b[] * value
a[] = b[] * c[]
a[] *= value
a[] *= b[]
a[] = b[] / value
a[] /= value
a[] -= b[] * value

CPU detection is done at runtime and picks which of none, mmx, sse, sse2 
or amd3dnow instructions to use.

Other operations are done using loop fusion.
