[webkit-dev] Functionality of create_activation and tear_off_activation

[Abhishek Bichhawat]

Hi,

We are working on a research project involving webkit. We are currently using Webkit-r122160 and trying to understand the functionality of two of the opcodes (op_create_activation and op_tear_off_activation), which are a part of the classical interpreter. Although, the classical interpreter has been phased out, we would appreciate if you could provide an insight into the functionality of the two opcodes. We are interested in the low-level details of the opcodes as to how they insert an object in the heap/register/scopechain and delete it from there. 

Thanks and Regards,
Abhishek
