...they don’t mean quite the same thing that they mean elsewhere. (Maybe that’s an argument for using a different construct.) There’s also a good chance that I’m being inconsistent in how I chose to represent catch clauses versus cleanup clauses. In the case you refer to, if an exception thrown by do_inner_thing() is caught by the int exception handler at lpad3, then we only want ~Iinner() to be called. If it is caught instead by the float handler, that will result in a different state transition and the call to ~Outer() will be made by the lpad1 cleanup. Having actually written that explanation now, I s...

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

...ut I have an idea for that which I’ll send out later today. If we go this way, the inlining code will need to be taught to merge the landingpad of the inlined function, but I think that will be pretty easy. So, here it is: void test() { try { Outer outer; try { Inner inner; do_inner_thing(); } catch (int) { handle_int(); } } catch (float) { handle_float(); } keep_going(); } ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ; Original ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ; Function Attrs: uwtable define void @_Z4testv() #0 { entry: %outer = alloca %class.Oute...
