Hi Reid and David, I just wanted to give you a heads up that I'm currently working on a problem where the WinEHPrepare outlining code stumbles and asserts while cloning code that references extracted landing pad values via PHI nodes that are in intermediate blocks that aren't being cloned. The test I'm looking at fails with an assertion claiming that llvm.eh.begincatch was called

...witch clauses have some fixed operands (RTTI, handler label) and some variable number of operands as required by the EH personality (catch object, adjectives) - Allow the 'resume' instruction to have 0, 1, or 2 successors, one of which can be a landingpad. - Add a 'resume' clause to landingswitches to allow them to continue the unwind process at another landingpad in the same function I've tried to sell this idea, but I'm getting push back suggesting that we fix it a different way. The most compelling suggestion is to have the existing landingpad instruction produce an i8* selector i...
