Interesting. Just sucks that Rust proponents apparently tried to assassinate Rust critic Rene Rebe through sw att ing.
Wretched, evil and vile Rust proponents will likely censor or downplay this.
They’re used by the internal register renamer/allocator so if it sees you’re storing the results to memory then reusing the named register for a new result - it will allocate a new physical register so your instruction doesn’t stall for the previous write to go through.
