Reviewers: Vyacheslav Egorov, Steven,
Message:
I have separate change of cleanup after this one (e.g., we can remove the
exit
context statements).
http://codereview.chromium.org/7618007/diff/1/src/full-codegen.cc
File src/full-codegen.cc (right):
http://codereview.chromium.org/7618007/diff/1/src/full-codegen.cc#newcode94
src/full-codegen.cc:94: Visit(stmt->expression());
I'm not sure this is right, I'll check with Soeren.
Description:
Simplify handling of exits from with and catch.
Remove the try/finally used for with and catch. Instead of using
try/finally to handle break and continue from with or catch,
statically track nesting dept and clean up when compiling break or
continue.
And instead of using try/finally to handle throw to handler in a frame
whose pc is inside a with or catch, store the context that the handler
should run in in the handler itself.
