3 * inline.adb (Add_Pending_Instantiation): Use greater-or-equal
4 in the comparison against the maximum number of instantiations.
6 2019-08-14 Ed Schonberg <schonberg@adacore.com>
8 * sem_aux.adb (Next_Rep_Item): If a node in the rep chain
9 involves a Ghost aspect it may have been replaced by a null
10 statement; use the original node to find next Rep_Item.
11 * repinfo.adb (List_Entities): Do not list an Ignored
12 Ghost_Entity, for which information may have been deleted.
14 2019-08-14 Bob Duff <duff@adacore.com>
16 * sem_prag.ads, sem_prag.adb
17 (Process_Compile_Time_Warning_Or_Error): In parameterless
18 version, improve detection of whether we are in a generic unit
19 to cover the case of an instance within a generic unit.
20 (Process_Compile_Time_Warning_Or_Error): Rename the
21 two-parameter version to be
22 Validate_Compile_Time_Warning_Or_Error, and do not export it.
23 Issue a warning if the condition is not known at compile time.
24 The key point is that the warning must be given only for pragmas
25 deferred to the back end, because the back end discovers
26 additional values that are known at compile time. Previous
27 changes in this ticket have enabled this by deferring to the
28 back end without checking for special cases such as 'Size.
29 (Validate_Compile_Time_Warning_Or_Error): Rename to be
30 Defer_Compile_Time_Warning_Error_To_BE.
31 * warnsw.ads, warnsw.adb (Warn_On_Unknown_Compile_Time_Warning):
32 Add new switches -gnatw_c and -gnatw_C to control the above
34 * doc/gnat_ugn/building_executable_programs_with_gnat.rst:
35 Document new switches.

40 * sem_ch12.adb (Might_Inline_Subp): Rework comment and restrict
41 the shortcut based on Is_Inlined to the back-end inlining case.
43 2019-08-14 Bob Duff <duff@adacore.com>
45 * inline.adb (Check_And_Split_Unconstrained_Function): Ignore
46 protected functions to get rid of spurious error. The
47 transformation done by this procedure triggers legality errors
48 in the generated code in this case.
50 2019-08-14 Bob Duff <duff@adacore.com>
52 * sem_prag.adb (Process_Compile_Time_Warning_Or_Error): Defer
53 processing to the back end in all cases where the pragma's
54 condition is not known at compile time during the front end
55 (except in generics), as opposed to detecting 'Size attributes
56 and the like. This ensures that we take advantage of whatever
57 can be compile-time known after running the back end, as opposed
58 to having the front end guess what the back end can do. Remove
59 a little duplicated code at the call site.
60 * gnat1drv.adb (Post_Compilation_Validation_Checks): Unlock the
61 Elists while in Validate_Compile_Time_Warning_Errors, because it
62 does analysis and name resolution, which sometimes involves

79 (Called_Pending_Instantiations): New table.
80 (Node_Table_Size): New constant.
81 (Node_Header_Num): New subtype.
82 (Node_Hash): New function.
83 (To_Pending_Instantiations): New hash table.
84 (Add_Inlined_Body): Bail out early for subprograms in the main
85 unit or subunit. Likewise if the Is_Called flag is set. If the
86 subprogram is an instance, invoke Add_Inlined_Instance. Call
87 Set_Is_Called earlier. If the subrogram is within an instance,
88 invoke Add_Inlined_Instance. Also deal with the case where the
89 call itself is within an instance.
90 (Add_Inlined_Instance): New procedure.
91 (Add_Inlined_Subprogram): Remove conditions always fulfilled.
92 (Add_Pending_Instantiation): Move the defence against ludicruous
93 number of instantiations to here. When back-end inlining is
94 enabled, associate an instantiation with its index in table and
95 mark a few selected kinds of instantiations as always needed.
96 (Initialize): Set Backend_Instances to No_Elist.
97 (Instantiate_Body): New procedure doing the work extracted
99 (Instantiate_Bodies): ...here. When back-end inlining is
100 enabled, loop over Called_Pending_Instantiations instead of
101 Pending_Instantiations.
102 (Is_Nested): Minor tweak.
103 (List_Inlining_Info): Also list the contents of
105 * sem_ch12.adb (Might_Inline_Subp): Return early if Is_Inlined
106 is set and otherwise set it before returning true.
107 (Analyze_Package_Instantiation): Remove the defence against
108 ludicruous number of instantiations. Invoke
109 Remove_Dead_Instance instead of doing the removal manually if
110 there is a guaranteed ABE.
112 2019-08-14 Gary Dismukes <dismukes@adacore.com>
114 * exp_ch3.adb (Predef_Spec_Or_Body): For an equality operation
115 of an interface type, create an expression function (that
116 returns False) rather than declaring an abstract function.
117 * freeze.adb (Check_Inherited_Conditions): Set Needs_Wrapper to
118 False unconditionally at the start of the loop creating wrappers
119 for inherited operations.
121 2019-08-14 Bob Duff <duff@adacore.com>
123 * table.adb: Assert that the table is not locked when increasing
124 Last, even if it doesn't cause reallocation. In other words,
125 assert that on operations that MIGHT cause reallocation.
126 * table.ads: Fix comment accordingly.
128 2019-08-14 Arnaud Charlet <charlet@adacore.com>
130 * doc/gnat_ugn/gnat_and_program_execution.rst: Remove
131 documentation of gnatelim.
133 2019-08-14 Bob Duff <duff@adacore.com>
135 * sem_prag.adb (Validate_Compile_Time_Warning_Error): Attach the
136 warning to the Sloc of the first pragma argument, rather than to
137 the pragma itself. This is to make pragmas processed after the
138 back end use the same Sloc as pragmas processed earlier, in the
139 front end. There's no reason for this discrepancy, and it
140 hinders further work on this ticket.
142 2019-08-14 Bob Duff <duff@adacore.com>
144 * sem.ads (Inside_A_Generic): Remove the ??? comment.
146 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>

155 2019-08-14 Bob Duff <duff@adacore.com>
157 * exp_aggr.adb (Init_Hidden_Discriminants): Avoid processing the
158 wrong discriminant, which could be of the wrong type.

218 2019-08-14 Ed Schonberg <schonberg@adacore.com>
220 * sem_util.adb (New_Copy_Tree, Visit_Entity): A quantified
221 expression includes the implicit declaration of the loop
222 parameter. When a quantified expression is copied during
223 expansion, for example when building the precondition code from
224 the generated pragma, a new loop parameter must be created for
225 the new tree, to prevent duplicate declarations for the same

310 component is an access to a class-wide type and the type of the
311 context is an access to a tagged type the relevant type is that
312 of the component (since in such case we may need to generate
313 implicit type conversions or dispatching calls).

463 derivations that have interface components located at fixed
464 positions and interface components located at variable offset.
465 The offset of components located at fixed positions is computed
466 using the dummy object (similar to the case where all the
467 interface components are located at fixed positions).
468 (Make_DT): Build the dummy object for all tagged types that
469 implement interface types (that is, build it also for types with

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

908 libgnat/s-valwch.ads: Change categorization of packages that
909 implement attribute 'Value from Pure to Preelaborate, to prevent
910 undesirable optimizations when the evaluation of the attribute
911 raises Constraint_Error, but subsequent use of the result of

934 result of this enhancement, the internal tables declared using
935 Index_Table have a length closer to the real needs, thus
936 avoiding the declaration of large arrays on 32-bit CCG targets.

1108 - Component_Is_Visible_In_SPARK is used to avoid doing pointer
1109 aliasing checks on components which are not visible in SPARK.
1110 - Emit_Messages returns True in the second phase of SPARK
1111 analysis. Error messages for failed aliasing checks are only
1112 output in this case.
1113 Additionally, errors on constructs not supported in SPARK are
1114 removed as duplicates of marking errors. Components are stored
1115 in the permission map using their original component to avoid
1116 inconsistencies between components of different views of the

3114 file. The Processing phase can now operate in multiple modes,
3115 all described by type Processing_Kind. Scenarios and targets
3116 are now distinct at the higher level, and carry their own
3117 representations. This eliminates the need to constantly
3118 recompute their attributes, and offers the various processors a
