| 2009-05-17 | Paul Boddie | raw annotate files changeset graph | Moved argument checking inside functions, changing the role of CheckFrame and introducing a separate FillDefaults instruction. Introduced a JumpWithFrameDirect instruction which is able, in conjunction with a new code_body_location attribute on Function and Class instances (for function bodies and class instantiator bodies respectively), to skip argument checking for invocations which could be checked at compile-time. Removed the invocation details from the common object structure. Improved various tests. |
