Slava Pestov	d957ae4e44	Performance improvements to make struct-arrays benchmark faster - improved optimization of ##unbox-any-c-ptr on ##box-displaced-alien; convert it to ##unbox-c-ptr where possible using class info stored in the ##bda instruction - make fcos, fsin, etc inline again; everything in math.libm inline again, except for fsqrt which is an intrinsic - convert min and max on floats to float-min and float-max - make min and max not inline, so that the above can work - struct-arrays: rice a bit so that more fixnums come up	2009-08-28 05:21:16 -05:00
Slava Pestov	21a012e3d7	compiler.cfg: Major restructuring -- do not compute liveness before local optimization, and instead change local optimizations to be more permissive of undefined values. Now, liveness is only computed once, after phi elimination and before register allocation. This means liveness analysis does not need to take phi nodes into account and can now use the new compiler.cfg.dataflow-analysis framework	2009-07-22 03:08:28 -05:00

Slava Pestov	44bfff7c7b	Rename ##load-indirect to ##load-reference since this is more descriptive; value numbering doesn't assign expressions to ##load-reference nodes since this would end up folding literals which were eq? but not =	2009-01-29 01:44:58 -06:00
