FTL should be able to handle exceptions
Comment 1 Filip Pizlo 2014-01-14 16:27:58 PST 
The FTL can always "handle" exceptions thrown from JS functions that it calls and that the FTL itself doesn't catch.  The FTL doesn't support op_catch so that's easy.

The things that need to be done are:

- Stack checks.
- Dealing with exceptions thrown by runtime functions.

Oh, right.  There's the part about slow path calls from inline caches.  That will be enjoyable.  https://bugs.webkit.org/show_bug.cgi?id=127020
