--- Comment #7 from Jonathan Wakely <redi at gcc dot gnu.org> --- Nearly all the plain C++ code can be fixed just by compiling it with -ftrapv, there's only one inline function where we can't control the compiler flags the user uses. So only that place needs to change (if I'm right about all the asm code being OK).
