They are concerned with "whole program" optimizations using a data base of information built up by analyzing each subroutine in turn. Code can then be generated for each routine with considerable knowledge of the side effects of subordinate called routines. This is a very ambitious project, going beyond even link time optimizations. The Oct. 'Computer' mag has a good general article on Rn. ------------------- Bron Nelson; Silicon Graphics, Inc Standard disclaimers. -- Send compilers articles to ima!compilers or, in a pinch, to Levine@YALE.EDU Plausible paths are { ihnp4 | decvax | cbosgd | harvard | yale | bbn}!ima Please send responses to the originator of the message -- I cannot forward mail accidentally sent back to compilers.
