3 * sem_prag.adb (Process_Compile_Time_Warning_Or_Error): Defer
4 processing to the back end in all cases where the pragma's
5 condition is not known at compile time during the front end
6 (except in generics), as opposed to detecting 'Size attributes
7 and the like. This ensures that we take advantage of whatever
8 can be compile-time known after running the back end, as opposed
9 to having the front end guess what the back end can do. Remove
10 a little duplicated code at the call site.
11 * gnat1drv.adb (Post_Compilation_Validation_Checks): Unlock the
12 Elists while in Validate_Compile_Time_Warning_Errors, because it
13 does analysis and name resolution, which sometimes involves

26 * inline.adb: Add with clauses for Alloc, Uintp, Table and
28 (Backend_Instances): New variable.
29 (Pending_Instantiations): ...here.
30 (Called_Pending_Instantiations): New table.
31 (Node_Table_Size): New constant.
32 (Node_Header_Num): New subtype.
33 (Node_Hash): New function.
34 (To_Pending_Instantiations): New hash table.
35 (Add_Inlined_Body): Bail out early for subprograms in the main
36 unit or subunit. Likewise if the Is_Called flag is set. If the
37 subprogram is an instance, invoke Add_Inlined_Instance. Call
38 Set_Is_Called earlier. If the subrogram is within an instance,
39 invoke Add_Inlined_Instance. Also deal with the case where the
40 call itself is within an instance.
41 (Add_Inlined_Instance): New procedure.
42 (Add_Inlined_Subprogram): Remove conditions always fulfilled.
43 (Add_Pending_Instantiation): Move the defence against ludicruous
44 number of instantiations to here. When back-end inlining is
45 enabled, associate an instantiation with its index in table and
46 mark a few selected kinds of instantiations as always needed.
47 (Initialize): Set Backend_Instances to No_Elist.
48 (Instantiate_Body): New procedure doing the work extracted
50 (Instantiate_Bodies): ...here. When back-end inlining is

54 (List_Inlining_Info): Also list the contents of
56 * sem_ch12.adb (Might_Inline_Subp): Return early if Is_Inlined
57 is set and otherwise set it before returning true.
58 (Analyze_Package_Instantiation): Remove the defence against
59 ludicruous number of instantiations. Invoke
60 Remove_Dead_Instance instead of doing the removal manually if
61 there is a guaranteed ABE.
63 2019-08-14 Gary Dismukes <dismukes@adacore.com>
65 * exp_ch3.adb (Predef_Spec_Or_Body): For an equality operation
66 of an interface type, create an expression function (that
67 returns False) rather than declaring an abstract function.

69 False unconditionally at the start of the loop creating wrappers
70 for inherited operations.
72 2019-08-14 Bob Duff <duff@adacore.com>

86 * sem_prag.adb (Validate_Compile_Time_Warning_Error): Attach the
87 warning to the Sloc of the first pragma argument, rather than to
88 the pragma itself. This is to make pragmas processed after the
89 back end use the same Sloc as pragmas processed earlier, in the
90 front end. There's no reason for this discrepancy, and it
91 hinders further work on this ticket.
93 2019-08-14 Bob Duff <duff@adacore.com>
95 * sem.ads (Inside_A_Generic): Remove the ??? comment.
97 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>

172 expression includes the implicit declaration of the loop
173 parameter. When a quantified expression is copied during
174 expansion, for example when building the precondition code from
175 the generated pragma, a new loop parameter must be created for
176 the new tree, to prevent duplicate declarations for the same

233 aubsidiary to Build_Derived_Record_Type. to enforce the rule

260 * sem_res.adb (Resolve_Selected_Component): When the type of the
261 component is an access to a class-wide type and the type of the
262 context is an access to a tagged type the relevant type is that
263 of the component (since in such case we may need to generate
264 implicit type conversions or dispatching calls).

268 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): Preanalyze

414 derivations that have interface components located at fixed
415 positions and interface components located at variable offset.
416 The offset of components located at fixed positions is computed
417 using the dummy object (similar to the case where all the

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

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

858 libgnat/s-valrea.ads, libgnat/s-valuns.ads,
859 libgnat/s-valwch.ads: Change categorization of packages that
860 implement attribute 'Value from Pure to Preelaborate, to prevent
861 undesirable optimizations when the evaluation of the attribute
862 raises Constraint_Error, but subsequent use of the result of
863 this evsaluation is removed by a subsequent optimization.

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

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