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

748 libgnat/s-valrea.ads, libgnat/s-valuns.ads,
749 libgnat/s-valwch.ads: Change categorization of packages that
750 implement attribute 'Value from Pure to Preelaborate, to prevent
751 undesirable optimizations when the evaluation of the attribute
752 raises Constraint_Error, but subsequent use of the result of
753 this evsaluation is removed by a subsequent optimization.

773 single letter literals and the Table built by the frontend would
774 have as many components as the length of the names string. As a
775 result of this enhancement, the internal tables declared using
776 Index_Table have a length closer to the real needs, thus
777 avoiding the declaration of large arrays on 32-bit CCG targets.
