20 (Analyze_Package_Instantiation): Do not instantiate the package
21 body because of inlining considerations if the instantiation is

23 the main unit. Add test on Back_End_Inlining to processing for

28 * exp_disp.adb (Make_Secondary_DT): Handle record type
29 derivations that have interface components located at fixed
30 positions and interface components located at variable offset.
31 The offset of components located at fixed positions is computed
32 using the dummy object (similar to the case where all the
33 interface components are located at fixed positions).
34 (Make_DT): Build the dummy object for all tagged types that
35 implement interface types (that is, build it also for types with
36 variable size components), and use the dummy object to compute

84 to generate proper checks when an actual for an in-out or out
85 parameter has a non-null access type. No constraints are
86 applied to an inbound access parameter, but on exit a not-null
87 check must be performed if the type of the actual requires it.

126 * libgnat/a-cbmutr.adb (Is_Reachable): Declare Idx to be of the
127 base subtype. Clearly it makes no sense to loop "while Idx >=
128 0", if Idx is of a nonnegative subtype.

402 2019-07-22 Ed Schonberg <schonberg@adacore.com>
404 * exp_ch4.adb (Expand_N_In): Do not suggest the use of attribute
405 'Valid as a replacement for a range check on a discrete type
406 when the bounds of the range are given by type conversions,
407 because in such a case there are distinct types involved and the
408 subbested attribute replacement would be misplaced.
410 2019-07-22 Yannick Moy <moy@adacore.com>
412 * sem_spark.adb (Get_Root_Object, Is_Path_Expression,
413 Is_Subpath_Expression): Add parameter Is_Traversal to adapt

473 libgnat/s-valrea.ads, libgnat/s-valuns.ads,
474 libgnat/s-valwch.ads: Change categorization of packages that
475 implement attribute 'Value from Pure to Preelaborate, to prevent
476 undesirable optimizations when the evaluation of the attribute
477 raises Constraint_Error, but subsequent use of the result of
478 this evsaluation is removed by a subsequent optimization.
480 2019-07-22 Ed Schonberg <schonberg@adacore.com>
482 * sem_warn.adb (Check_References): Do not emit s warning on a

493 arrays initialized with a qualified expression.
494 * libgnat/s-imenne.adb (Image_Enumeration_8,
495 Image_Enumeration_16, Image_Enumeration_32): Define the index of
496 Index_Table with range Natural'First .. Names'Length since in
497 the worst case all the literals of the enumeration type would be
498 single letter literals and the Table built by the frontend would
499 have as many components as the length of the names string. As a
500 result of this enhancement, the internal tables declared using
501 Index_Table have a length closer to the real needs, thus
502 avoiding the declaration of large arrays on 32-bit CCG targets.

539 * sem_ch3.adb (Convert_Bound): Subsidiary of
540 Floating_Point_Type_Declaration, to handle properly range
