In a previous posting, I asked for pointers to work on compressing object code. In case it wasn't clear what I meant, I'm looking for algorithms _specifically_designed_ to compress compiled code, maybe even tuned to a particular instruction set, _not_ for general-purpose compression algorithms. I'm looking for large compression factors, not generality, and I'd prefer algorithms that are _very_ fast at doing that specific kind of thing. (Slow algorithms would be interesting, too, if only to give some kind of how effective things _can_ be.) I heard somewhere that the Acorn RISC machine OS uses some kind of compression for system code. Does anybody know if this is true, or any details of their scheme? (Or how well it works?) I've also heard a rumor that SPARC code can be compressed 2x, but that may have just been somebody's guess. Has anybody actually done this? Michael Lam lam@bert.eecs.uic.edu EECS Dept.
