Dunno about MMX/3DNow-type extensions, but most of the ISA
extensions also include some prefetching/memory-hint
instructions that help to improve cache behavior during
specific kinds of memory-intensive computation. Specifically,
the recent Intel SSE (I've forgotten what it stands for)
extensions include some instructions that seem to be generated
by newer compilers from Intel and which seem to have helped
Intel's recent SPECfp scores. Search around in comp.arch
for some threads that discuss this.
