bit conversion of floats to integers #293

Open Itay2805 opened 1 year ago

Itay2805 commented 1 year ago

It would be nice to have a way to easily and efficiently do a bit conversion of a float to int, right now code would require to essentially do 

mov f(var), float_value
mov integer_value, i32(var)

which of course is not optimal as it requires a memory access

Thank you for your proposal.

I have such plans as a lot of dynamic language implementations use tagged values and boxing/unboxing fp values requires the bitwise conversions. Simply I can not say when it will be done. I have long list todo for MIR project and unfortunately I can spend only small part of my work time on MIR project.
