* Add `try_use_var` method to `cranelift-frontend`. - Unlike `use_var`, this method does not panic if the variable has not been defined before use * Add `try_declare_var` and `try_def_var`. - Also implement Error for error enums. * Use `write!` macro. * Add `write!` use I missed.
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.
