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

423 libgnat/s-valrea.ads, libgnat/s-valuns.ads,
424 libgnat/s-valwch.ads: Change categorization of packages that
425 implement attribute 'Value from Pure to Preelaborate, to prevent
426 undesirable optimizations when the evaluation of the attribute
427 raises Constraint_Error, but subsequent use of the result of
428 this evsaluation is removed by a subsequent optimization.

450 result of this enhancement, the internal tables declared using
451 Index_Table have a length closer to the real needs, thus
452 avoiding the declaration of large arrays on 32-bit CCG targets.
