674 'Valid as a replacement for a range check on a discrete type
675 when the bounds of the range are given by type conversions,
676 because in such a case there are distinct types involved and the

742 libgnat/s-valrea.ads, libgnat/s-valuns.ads,
743 libgnat/s-valwch.ads: Change categorization of packages that
744 implement attribute 'Value from Pure to Preelaborate, to prevent
745 undesirable optimizations when the evaluation of the attribute
746 raises Constraint_Error, but subsequent use of the result of
747 this evsaluation is removed by a subsequent optimization.

769 result of this enhancement, the internal tables declared using
770 Index_Table have a length closer to the real needs, thus
