In #4502 we discovered a bug in the switch api where it would emit `icmp_imm`'s with types that were not able to fully represent the destination index. We now reject these inputs. The index val must always have a type that is capable of addressing the entire range of inputs.
This crate provides a straightforward way to create a
Cranelift IR function and fill it with
instructions translated from another language. It contains an SSA construction
module that provides convenient methods for translating non-SSA variables into
SSA Cranelift IR values via use_var and def_var calls.
