Only when the frame contains constants that are synched to memory and nothing else that's problematic---then it can become mergable by just forgetting about the constants. I don't expect it to be the common case, but it happens right now for the stack check on function entry where the locals are constants (the undefined value). For total correctness with the debugger, the stack check should probably be special-cased and avoid the double jump but I'd still like to avoid it in other cases too. http://codereview.chromium.org/13234 --~--~---------~--~----~------------~-------~--~----~ v8-dev mailing list [email protected] http://groups.google.com/group/v8-dev -~----------~----~----~----~------~----~------~--~---
