67 derivations that have interface components located at fixed
68 positions and interface components located at variable offset.
69 The offset of components located at fixed positions is computed
70 using the dummy object (similar to the case where all the

122 to generate proper checks when an actual for an in-out or out
123 parameter has a non-null access type. No constraints are
124 applied to an inbound access parameter, but on exit a not-null

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

286 node but its expression instead, after having fetched its
287 current value. Clear the Do_Range_Check flag on entry. Return

362 (gnat_to_gnu): Leave the exception pointer alone for reraise.
363 (add_cleanup): Handle EH_ELSE_EXPR, require it by itself.

367 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations,
368 Freeze_Entity_Checks): Include Aspect_CPU with other aspects

403 operational, do not ecamine the full view of a private type to

440 2019-07-22 Ed Schonberg <schonberg@adacore.com>
442 * exp_ch4.adb (Expand_N_In): Do not suggest the use of attribute
443 'Valid as a replacement for a range check on a discrete type
444 when the bounds of the range are given by type conversions,
445 because in such a case there are distinct types involved and the
446 subbested attribute replacement would be misplaced.
448 2019-07-22 Yannick Moy <moy@adacore.com>
450 * sem_spark.adb (Get_Root_Object, Is_Path_Expression,
451 Is_Subpath_Expression): Add parameter Is_Traversal to adapt
452 these functions to the case of paths returned from a traversal
454 (Read_Indexes): Handle the case of an if-expression or

511 libgnat/s-valrea.ads, libgnat/s-valuns.ads,
512 libgnat/s-valwch.ads: Change categorization of packages that
513 implement attribute 'Value from Pure to Preelaborate, to prevent
514 undesirable optimizations when the evaluation of the attribute
515 raises Constraint_Error, but subsequent use of the result of
516 this evsaluation is removed by a subsequent optimization.
518 2019-07-22 Ed Schonberg <schonberg@adacore.com>
520 * sem_warn.adb (Check_References): Do not emit s warning on a

531 arrays initialized with a qualified expression.
532 * libgnat/s-imenne.adb (Image_Enumeration_8,
533 Image_Enumeration_16, Image_Enumeration_32): Define the index of
534 Index_Table with range Natural'First .. Names'Length since in
535 the worst case all the literals of the enumeration type would be
536 single letter literals and the Table built by the frontend would
537 have as many components as the length of the names string. As a
538 result of this enhancement, the internal tables declared using
539 Index_Table have a length closer to the real needs, thus
540 avoiding the declaration of large arrays on 32-bit CCG targets.
