[PATCH] D98798: Produce warning for performing pointer arithmetic on a null pointer.

[Jamie Schmeiser via Phabricator via cfe-commits]

jamieschmeiser added a comment.

@rsmith I separated the C and C++ messages in response to your comments and changed the C++ message to state that "performing pointer subtraction with a null pointer may have undefined behavior" to address your concerns.  Are you satisfied?  @thakis, the warning no longer fires in the MS headers according to @hans and there is separate option control over this warning.  Is this sufficient?  @efriedma, thank you for reviewing/approving the original but these changes were sufficiently different that I thought a new review would be beneficial.  Are you still satisfied with the resulting changes?
