        * cgraph.c (cgraph_edge::redirect_call_stmt_to_callee): If redirecting
        to noreturn e->callee->decl that has void return type and void
        arguments, adjust gimple_call_fntype and remove lhs even if it had
        previously addressable type.

        * g++.dg/opt/pr71387.C: New test.
