32 * libgnat/a-cbmutr.adb (Is_Reachable): Declare Idx to be of the

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

379 libgnat/s-valrea.ads, libgnat/s-valuns.ads,
380 libgnat/s-valwch.ads: Change categorization of packages that
381 implement attribute 'Value from Pure to Preelaborate, to prevent
382 undesirable optimizations when the evaluation of the attribute
383 raises Constraint_Error, but subsequent use of the result of
384 this evsaluation is removed by a subsequent optimization.

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