10 2019-08-12 Bob Duff <duff@adacore.com>
12 * libgnat/a-cbmutr.adb (Is_Reachable): Declare Idx to be of the

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

359 libgnat/s-valrea.ads, libgnat/s-valuns.ads,
360 libgnat/s-valwch.ads: Change categorization of packages that
361 implement attribute 'Value from Pure to Preelaborate, to prevent
362 undesirable optimizations when the evaluation of the attribute
363 raises Constraint_Error, but subsequent use of the result of
364 this evsaluation is removed by a subsequent optimization.

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

563 analysis. Error messages for failed aliasing checks are only
565 Additionally, errors on constructs not supported in SPARK are
566 removed as duplicates of marking errors. Components are stored
