Perform a search over block predecessors trying to find loops of unreachable predecessors. We do this by iterating on predecessors and marking them as visited, stopping if we find a previously visited block or if we find a block with multiple predecessors. This issue was found by the CLIF fuzzer in #3094.
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.
