I got [only :-(] 5.4% faster on ARM. And I think about 1% faster on x86. (for boring standard 32 bit IVs) pp_divide seems to slow down a lot if given the integer first else FP treatment, so I've not done that yet (will need to be FP if first operand is integer and greater than the size NV preserves to make 0xFFFFFFFFFFFFFFFF / 3 work, but needing to even have that code can be conditionally compiled in) I've not touched pp_modulo (yet) Simon's profiles seemed to show it taking a very long time, so it appears there's something really bad happening there. Did anyone have any idea why it seemed to be so slow? Nicholas ClarkThread Previous | Thread Next
