Hi James, Thank you for the response. I understand the concern about malloc/free hooks. Could we detect that a program has setup malloc hooks (assuming we're in a whole program compilation) and make assumptions (such as onlyAccessesArgMem()) when the program hasn't setup malloc hooks? Using a command line flag could be one option too. I'm currently working on a program where having

If ReadNone is set, it means it doesn't access any of the visible (accessible) states. - Vaivaswatha On Fri, Dec 4, 2015 at 3:17 PM, James Molloy <james at jamesmolloy.co.uk> wrote: > Hi, > > I don't think the attribute as is is strong enough to do what you
