I've done a quick search for instruction scheduling especially for
Itanium / instruction-level parallelism. Are there some main texts
(academic papers, etc.) of main techniques on this topic? I'm
interested in implementing scheduling for my toy-compiler, to try on
Itanium. It doesn't have to be the best technique around, in fact, the
simpler the better (more advanced will be attempted later!).


The book "Engineering a Compiler" by Cooper and Torczon (Morgan
Kaufmann) has an introductory chapter which reviews instruction
scheduling but I'm not sure whether it outlines a specific algorithm
for it.
