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	e21ca289c3	compiler.cfg.representations: new pass to make global unboxing decisions, relies on new compiler.cfg.loop-detection pass for loop nesting information	2009-08-08 00:24:46 -05:00
