38 derivations that have interface components located at fixed
39 positions and interface components located at variable offset.
40 The offset of components located at fixed positions is computed

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

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

482 libgnat/s-valrea.ads, libgnat/s-valuns.ads,
483 libgnat/s-valwch.ads: Change categorization of packages that
484 implement attribute 'Value from Pure to Preelaborate, to prevent
485 undesirable optimizations when the evaluation of the attribute
486 raises Constraint_Error, but subsequent use of the result of
487 this evsaluation is removed by a subsequent optimization.

503 * libgnat/s-imenne.adb (Image_Enumeration_8,
504 Image_Enumeration_16, Image_Enumeration_32): Define the index of
505 Index_Table with range Natural'First .. Names'Length since in
506 the worst case all the literals of the enumeration type would be
507 single letter literals and the Table built by the frontend would
508 have as many components as the length of the names string. As a
509 result of this enhancement, the internal tables declared using
510 Index_Table have a length closer to the real needs, thus
511 avoiding the declaration of large arrays on 32-bit CCG targets.
