58 derivations that have interface components located at fixed
59 positions and interface components located at variable offset.
60 The offset of components located at fixed positions is computed
61 using the dummy object (similar to the case where all the

113 to generate proper checks when an actual for an in-out or out
114 parameter has a non-null access type. No constraints are

155 * libgnat/a-cbmutr.adb (Is_Reachable): Declare Idx to be of the
156 base subtype. Clearly it makes no sense to loop "while Idx >=

434 'Valid as a replacement for a range check on a discrete type
435 when the bounds of the range are given by type conversions,
436 because in such a case there are distinct types involved and the
437 subbested attribute replacement would be misplaced.
439 2019-07-22 Yannick Moy <moy@adacore.com>
441 * sem_spark.adb (Get_Root_Object, Is_Path_Expression,

502 libgnat/s-valrea.ads, libgnat/s-valuns.ads,
503 libgnat/s-valwch.ads: Change categorization of packages that
504 implement attribute 'Value from Pure to Preelaborate, to prevent
505 undesirable optimizations when the evaluation of the attribute
506 raises Constraint_Error, but subsequent use of the result of
507 this evsaluation is removed by a subsequent optimization.

523 * libgnat/s-imenne.adb (Image_Enumeration_8,

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