The code changes modify the
cir.if
andcir.scope
operations to ensure that their code regions are properly terminated. Previously, the if/else and scope regions could be left completely empty which is non-trivially expected in most code inspecting these ops. This led, for example, to a crash when and if clause was left empty in the source code.Now, the child regions must be terminated, either explicitly or implicitly by the default builder and assembly parser. This change improves the clarity and correctness of the code.
