You might find some of what you want in this book about DEC's PL/I compiler:


Engineering a Compiler: Vax-II Code Generation and Optimization
Patricia Anklam
1982


This page:


http://compilers.iecc.com/comparch/article/87-07-021


mentions a book on DEC's BLISS compiler:


The Design of an Optimizing Compiler
William Allan Wulf
1980


Louis
[I have both books. The first one tells you all about code generation
for the Vax as done by their PL/I and C compiler. It was a pretty
normal compiler for the late 70s, reasonable common subexpression
handling and pre-graph-coloring register allocation. They spent a lot
of effort in instruction selection, to use all of the Vax instructions
and address modes. The Wulf book is a classic, but the target was the
PDP-11, not the Vax. -John]
