Re: Possible data allocation and instruction scheduling algo...

Regarding instruction scheduling: You are referring to the Pentium
processor. The PPro upwards operates very differently. See the
optimization manual at developer.intel.com for a description of the
internal operation of the P4 (plus a huge amount of optimization
advice).

Well, this depends very much on your definition of "artificial
intelligence". If you define "ai" as some kind of magic which has not
been implemented or thought of yet, then the answer is "I don't know".
If you more realistically define it as the compiler doing something
similar to a good programmer or achieving similar results then the
answer is that good compilers already do optimize the "assembly
output" (instruction selection + scheduling etc.) to a significant
extent.
Anyhow, no compiler matches an experienced human assembly programmer
(or even comes close, at least in most cases).
