sg	7530393d6f	* Fix for containsPointerRef: Loop now runs in the correct range	2000-11-08 16:04:34 +00:00
Jonas Maebe	767ecef9bb	* fixed bug in arrayRefsEq ... * object/class fields are now handled the same as local/global vars and parameters (ie. a write to a local var can now never destroy a class field)	2000-11-03 18:06:26 +00:00
Jonas Maebe	a4fde73649	+ register renaming ("fixes" bug1088) ... * changed command line options meanings for optimizer: O2 now means peepholopts, CSE and register renaming in 1 pass O3 is the same, but repeated until no further optimizations are possible or until 5 passes have been done (to avoid endless loops) * changed aopt386 so it does this looping * added some procedures from csopt386 to the interface because they're used by rropt386 as well * some changes to csopt386 and daopt386 so that newly added instructions by the CSE get optimizer info (they were simply skipped previously), this fixes some bugs	2000-10-24 10:40:52 +00:00
