...er inner; // eh_state = 3 do_inner_thing(); // eh_state = 2 (because we’re going to destruct inner here) } catch (int) { // eh_state = 4 handle_int(); } // eh_state = 0 (because we’re going to destruct outer here) } catch (float) { // eh_state = 5 handle_float(); } // eh_state = -1; keep_going(); } Basically, the EH state needs to change any time we enter a new scope or construct a new object that needs to be destructed and catch handlers get their own state. Then things get peeled away as the conditions that created the state go away. I don’t t...

I am working on adding support for C++ exception handling when compiling for a native Windows target (that is a target with "MSVC" specified as the environment). Because of differences between how the native Windows runtime handles exceptions and the Itanium-based model used by current LLVM exception handling code, I believe this will require some extensions to the LLVM IR, though

...ning code will need to be taught to merge the landingpad of the inlined function, but I think that will be pretty easy.
