> Currently jitrino OPT optimizes float-to-integer conversion by injecting (inlining) required
code into managed method. Unfortunatelly it lacks such optimization for opposite (integer-to-float)
conversion. Such optimization may have noticable effect on SciMark workload.
> I also noticed that DRLVM helper VM_RT_F2I generates wrapper code (LIL stub) around C
function which implements float-to-integer conversion. It makes sense to get rid of such wrapper
and call C function directly. (or remove this helper at all and let jitrino implement it)
> Thanks
