I my PowerPC Oberon compiler, I use SSA form and sparse data flow
techniques. So far I have been very pleased with the results. The
important papers are (from memory)
The Oct 91, Cytron et al paper on "Efficiently Constructing Static Single
Assignment Form and the Control Dependence Graph".
The Apr 91, Wegman and Zadeck paper on "Constant propagation with
conditional branches". There's a mention os so-called SSA edges which
encapsulate the du chains in SSA form.
The SIGPLAN 91 paper (Cytron, Ferrante, and ?) on Sparse Data Flow graphs.
And The SIGPLAN 92 paper (Dhamdere, Rosen, Zadeck) on slotwise analysis.
The various comp.compilers bibliographies have lots more information as
