--- Comment #7 from Alejandro Colomar <alx at kernel dot org> --- (In reply to Jonathan Wakely from comment #6) > Not warning at all for a literal -1 seems reasonable to me. It's such a > common idiom to compare to -1 for error checks. > > So suppress the warning only for the literal -1 (and no other spellings, > such as -1L or ~0), and only if it's being compared to an unsigned integer > type of rank not less than the rank of int. Yes, precisely that. > The suggestion makes sense to me. Thanks! :-)
