|  Slava Pestov | e27adb2830 | compiler: re-architect low-level optimizer to allow more than one output value per instruction | 2010-07-13 07:40:14 -04:00 | 
				
					
						|  Doug Coleman | 3f3d57032b | Delete empty unit tests files, remove 1- and 1+, reorder IN: lines in a lot of places, minor refactoring | 2009-08-13 19:21:44 -05:00 | 
				
					
						|  Slava Pestov | 4b7ba38aab | compiler.cfg: virtual registers are integers now, and representations are stored off to the side. Fix bug in representation selection that would manifest if a value was used as a float and a fixnum in different branches; cannot globally unbox float in this case | 2009-08-08 04:02:18 -05:00 | 
				
					
						|  Slava Pestov | 725280d424 | Split off the notion of a register representation from a register class | 2009-08-07 17:44:50 -05:00 | 
				
					
						|  Slava Pestov | dac7edd2ab | compiler.cfg.def-use: remove compute-def-use word, passes have to call compute-defs or compute-uses now; compiler.cfg.ssa.liveness: don't compute dominance and def-use first since destruction does already | 2009-08-02 19:12:32 -05:00 |
