Previously `unroll_stmt` would recurse over the smtlib expressions as well as recursively follow not-yet-emitted definitions the current expression depends on. While the depth of smtlib expressions generated by yosys seems to be reasonably bounded, the dependency chain of not-yet-emitted definitions can grow linearly with the size of the design and linearly in the BMC depth. This makes `unroll_stmt` use a `list` as stack, using python generators and `recursion_helper` function to keep the overall code structure of the previous recursive implementation. |
