After we add any instruction to an EBB, we can't add EBB parameters anymore. There is an assertion in `append_ebb_param` to detect this error, but the backtrace generated doesn't give any hint what happened. We add an error message to the assertion so the user can understand what is wrong. fixes #1003
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.
