The cases caught are where the size is the same as the modulus (e.g. a modulus of 7 with a size of 7 bits), and modulus values of 32 or 64 with no size clause. The guess in both cases is that 2**x was intended -rather than x. The default is that these warnings are given. +rather than x. In addition expressions of the form 2*x for small x +generate a warning (the almost certainly accurate guess being that +2**x was intended). The default is that these warnings are given. @item -gnatw.M @emph{Disable warnings on suspicious modulus values.} |
