| stable_iterator | stable_begin () const |
| Create a stable reference to the top of the EH stack. | |
| stable_iterator | stabilize (iterator it) const |
| Translates an iterator into a stable_iterator. | |
| iterator | find (stable_iterator save) const |
| Turn a stable reference to a scope depth into a unstable pointer to the EH stack. | |

| Add a branch fixup to the current cleanup scope. | |
| unsigned | getNumBranchFixups () const |
| BranchFixup & | getBranchFixup (unsigned I) |
| void | popNullFixups () |
