[Bug middle-end/35412] Correctness with -ftrapv depends on libcall notes

--- Comment #1 from rguenth at gcc dot gnu dot org 2008-02-29 23:33 --- -ftrapv is seriously broken and nobody wants to fix it; so the most appealing solution is to remove support for -ftrapv. See PR19020, especially the libcall part is broken as well. -- rguenth at gcc dot gnu
