...I propose making @__clang_call_terminate an intrinsic: … That sounds like a good starting point. > Chandler expressed strong concerns about this design, however, as @llvm.eh.get_capture_block adds an ordering constraint on CodeGen. Once you add this intrinsic, we *have* to do frame layout of @_Z13do_some_thingRi *before* we can emit code for all the callers of @llvm.eh.get_capture_block. Today, this is easy, because module order defines emission order, but in the great glorious future, codegen will hopefully be parallelized, and then we've inflicted this horrible constraint on the innocent. > His s...
