Hi.As discussed with Marc, I'm suggesting to mark user-provided delete operators with DECL_SET_IS_OPERATOR_DELETE in order to allow possible DCE for it. I've checked that clang can also optimize that situation out. Patch can bootstrap on x86_64-linux-gnu and survives regression tests. Ready to be installed?
