If you have deep pipelines, being | forced to make worst-case assumptions at routine entry can be quite limiting. | By doing reorganization in (or after) the linker, you know all the pre- | conditions a routine will have to deal with (unless someone takes it's | address, of course - then you go back to worst-case, unless you have a VERY | smart and lucky linker). Except of course if you are using object oriented techniques, and are calling through a function pointer. In which case, the linker has to fall back to the normal case of using fixed defaults. -- Michael Meissner email: meissner@osf.org phone: 617-621-8861 Open Software Foundation, 11 Cambridge Center, Cambridge, MA, 02142 Considering the flames and intolerance, shouldn't USENET be spelled ABUSENET?
