My webkkit version 60* and many custom features are verified, so it is hard
to update it. But after check the Changlog, i find that GC is related with JIT
Infrastructure and ARCH code.

Hi,
Does webkit javascript engine SquirrelFish have Continuations support? Like
the one in Rhino JavaScript
engine:
https://developer.mozilla.org/en/New_in_Rhino_1.7R2
Basically, can I save the execution context of SquirrelFish and then resume
later on?
Thank you.

The "load" opcode's only purpose is to move a
