Slava Pestov	1d7089dc04	compiler: combine ##load-constant followed by ##alien-double into a ##load-double on x86-32, saving an integer register	2010-04-18 21:42:45 -05:00
Slava Pestov	20dfbf7ac8	More SIMD work - Rename SIMD types and register representations: <type>-<count> rather than <count><type>-array - Make a functor to define 256-bit vector types, use it to define float-8 type - Make SIMD instructions pure-insns so that they participate in value numbering	2009-09-03 20:58:56 -05:00
Slava Pestov	2d575d7ec9	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	4921b819e0	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
