Slava Pestov ec70e1d714 More minor documentation tweaks 2009-08-30 06:32:20 -05:00
Slava Pestov 0db01f6d5f compiler.cfg.linear-scan now supports partial sync-points where all registers are spilled; taking advantage of this, there are new trigonometric intrinsics which yield a 2x performance boost on benchmark.struct-arrays and a 25% boost on benchmark.partial-sums 2009-08-30 04:52:01 -05:00
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
