WebMay 31, 2024 · Making some rustc intrinsics (ctpop, cttz, ctlz and bswap) const fns.This is a pre-step to being able to make swap_bytes, to_be and from_be constant functions. That in itself could be ergonomic and useful. But even better is that it would allow Ipv4Addr::new etc becoming const fns as well.Which might be really useful since I find it quite common to … WebToday a CTPOP (Count Population) instruction is avail- able on most modern computer architectures including the Intel Itanium, Compaq Alpha, Motorola Power PC, Sun UltraSparc and Cray, or can be emulated with non-memory referencing shift/add instructions, to count selected bits in a bit-map. Ideal Hash Trees With AMT’s†3 WebFeb 5, 2024 · The output of intrinsic functions like ctpop, cttz, ctlz have limited range from 0 to bitwidth. So if the truncate destination type can hold the source bitwidth size, we can just ignore the truncate and use the truncate src to do combination. dynasty global investments
