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

647 libgnat/s-valrea.ads, libgnat/s-valuns.ads,
648 libgnat/s-valwch.ads: Change categorization of packages that
649 implement attribute 'Value from Pure to Preelaborate, to prevent
650 undesirable optimizations when the evaluation of the attribute
651 raises Constraint_Error, but subsequent use of the result of
652 this evsaluation is removed by a subsequent optimization.

670 Index_Table with range Natural'First .. Names'Length since in
671 the worst case all the literals of the enumeration type would be
672 single letter literals and the Table built by the frontend would
673 have as many components as the length of the names string. As a
674 result of this enhancement, the internal tables declared using
675 Index_Table have a length closer to the real needs, thus
676 avoiding the declaration of large arrays on 32-bit CCG targets.
