The pretty-printing had swapped dst and src2; this was introduced when we moved to RA2 (sorry about that! IMHO we should do something to automate the mapping between regalloc arg collection and pretty printing/emission). `src2` comes at the end because it has a variable number of register mentions; this is in line with how many of the other inst formats work. Actual emitted code was never incorrect, just the pretty-printing. Updated test golden outputs look correct to me now, including the one that we saw was incorrect in #3945.
This crate contains the core Cranelift code generator. It translates code from an intermediate representation into executable machine code.
