I've noticed some recent postings in comp.compilers about an RTL representation used by the GNU compilers. I'm interested in reading up on this. Is there a reference anybody can suggest?

You may want to get the distribution from prep.ai.mit.edu or some other ftp archive. The idea of using RTL came from the U. of Arizona Portable Optimizer, written by Jack Davidson and Christopher Fraser. This is described in "Register Allocation and Exhaustive Peephole Optimization", Software Practice and Experience 14 (9), Sept. 1984, pp. 857-866 There is another paper providing a quick overview of RTL (~ 2-3 pages) in Michael Tiemann, "The GNU instruction scheduler" (course report from Stanford, I can't remember the number :-( ) You also may want to read what the Dragon book says about code generator generators, there are many parallels, but where they use trees as intermediate representation, GNU uses lists. bye, mike Michael K.
