88 Container. Add a type Array_Base which replaces the previous
89 Elements attribute of Container.
90 (Content_Init): New subprogram. It is used to initialize the
91 Base attribute of Container.

127 Ghost_Entity, for which information may have been deleted.
129 2019-08-14 Bob Duff <duff@adacore.com>
131 * sem_prag.ads, sem_prag.adb
132 (Process_Compile_Time_Warning_Or_Error): In parameterless
133 version, improve detection of whether we are in a generic unit
134 to cover the case of an instance within a generic unit.
135 (Process_Compile_Time_Warning_Or_Error): Rename the
136 two-parameter version to be
137 Validate_Compile_Time_Warning_Or_Error, and do not export it.
138 Issue a warning if the condition is not known at compile time.
139 The key point is that the warning must be given only for pragmas
140 deferred to the back end, because the back end discovers
141 additional values that are known at compile time. Previous
142 changes in this ticket have enabled this by deferring to the
143 back end without checking for special cases such as 'Size.
144 (Validate_Compile_Time_Warning_Or_Error): Rename to be
145 Defer_Compile_Time_Warning_Error_To_BE.

158 2019-08-14 Bob Duff <duff@adacore.com>
160 * inline.adb (Check_And_Split_Unconstrained_Function): Ignore
161 protected functions to get rid of spurious error. The
162 transformation done by this procedure triggers legality errors
163 in the generated code in this case.
165 2019-08-14 Bob Duff <duff@adacore.com>
167 * sem_prag.adb (Process_Compile_Time_Warning_Or_Error): Defer
168 processing to the back end in all cases where the pragma's
169 condition is not known at compile time during the front end
170 (except in generics), as opposed to detecting 'Size attributes
171 and the like. This ensures that we take advantage of whatever
172 can be compile-time known after running the back end, as opposed
173 to having the front end guess what the back end can do. Remove
174 a little duplicated code at the call site.
175 * gnat1drv.adb (Post_Compilation_Validation_Checks): Unlock the
176 Elists while in Validate_Compile_Time_Warning_Errors, because it
177 does analysis and name resolution, which sometimes involves

195 (Node_Table_Size): New constant.
196 (Node_Header_Num): New subtype.
197 (Node_Hash): New function.
198 (To_Pending_Instantiations): New hash table.
199 (Add_Inlined_Body): Bail out early for subprograms in the main
200 unit or subunit. Likewise if the Is_Called flag is set. If the
201 subprogram is an instance, invoke Add_Inlined_Instance. Call
202 Set_Is_Called earlier. If the subrogram is within an instance,
203 invoke Add_Inlined_Instance. Also deal with the case where the
204 call itself is within an instance.
205 (Add_Inlined_Instance): New procedure.
206 (Add_Inlined_Subprogram): Remove conditions always fulfilled.
207 (Add_Pending_Instantiation): Move the defence against ludicruous
208 number of instantiations to here. When back-end inlining is
209 enabled, associate an instantiation with its index in table and
210 mark a few selected kinds of instantiations as always needed.
211 (Initialize): Set Backend_Instances to No_Elist.
212 (Instantiate_Body): New procedure doing the work extracted
214 (Instantiate_Bodies): ...here. When back-end inlining is
215 enabled, loop over Called_Pending_Instantiations instead of
216 Pending_Instantiations.
217 (Is_Nested): Minor tweak.
218 (List_Inlining_Info): Also list the contents of
220 * sem_ch12.adb (Might_Inline_Subp): Return early if Is_Inlined
221 is set and otherwise set it before returning true.
222 (Analyze_Package_Instantiation): Remove the defence against
223 ludicruous number of instantiations. Invoke
224 Remove_Dead_Instance instead of doing the removal manually if
225 there is a guaranteed ABE.
227 2019-08-14 Gary Dismukes <dismukes@adacore.com>
229 * exp_ch3.adb (Predef_Spec_Or_Body): For an equality operation
230 of an interface type, create an expression function (that
231 returns False) rather than declaring an abstract function.
232 * freeze.adb (Check_Inherited_Conditions): Set Needs_Wrapper to
233 False unconditionally at the start of the loop creating wrappers
234 for inherited operations.
236 2019-08-14 Bob Duff <duff@adacore.com>
238 * table.adb: Assert that the table is not locked when increasing

248 2019-08-14 Bob Duff <duff@adacore.com>
250 * sem_prag.adb (Validate_Compile_Time_Warning_Error): Attach the
251 warning to the Sloc of the first pragma argument, rather than to
252 the pragma itself. This is to make pragmas processed after the
253 back end use the same Sloc as pragmas processed earlier, in the
254 front end. There's no reason for this discrepancy, and it
255 hinders further work on this ticket.
257 2019-08-14 Bob Duff <duff@adacore.com>
259 * sem.ads (Inside_A_Generic): Remove the ??? comment.
261 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>

336 expression includes the implicit declaration of the loop
337 parameter. When a quantified expression is copied during
338 expansion, for example when building the precondition code from
339 the generated pragma, a new loop parameter must be created for
340 the new tree, to prevent duplicate declarations for the same

578 derivations that have interface components located at fixed
579 positions and interface components located at variable offset.
580 The offset of components located at fixed positions is computed
581 using the dummy object (similar to the case where all the
582 interface components are located at fixed positions).
583 (Make_DT): Build the dummy object for all tagged types that
584 implement interface types (that is, build it also for types with
585 variable size components), and use the dummy object to compute
586 the offset of all tag components located at fixed positions when
587 initializing the Interface_Table object.

632 * exp_ch6.adb (Expand_Actuals. Add_Call_By_Copy_Code): Add code
633 to generate proper checks when an actual for an in-out or out
634 parameter has a non-null access type. No constraints are
635 applied to an inbound access parameter, but on exit a not-null

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

954 'Valid as a replacement for a range check on a discrete type
955 when the bounds of the range are given by type conversions,
956 because in such a case there are distinct types involved and the
957 subbested attribute replacement would be misplaced.
959 2019-07-22 Yannick Moy <moy@adacore.com>
961 * sem_spark.adb (Get_Root_Object, Is_Path_Expression,

997 2019-07-22 Javier Miranda <miranda@adacore.com>
999 * sem_res.adb (Resolve_Actuals): Replace code that displaces the

1001 dispatch table by a type conversion (which takes care of
1002 handling all cases).

1023 libgnat/s-valwch.ads: Change categorization of packages that
1024 implement attribute 'Value from Pure to Preelaborate, to prevent
1025 undesirable optimizations when the evaluation of the attribute
1026 raises Constraint_Error, but subsequent use of the result of
1027 this evsaluation is removed by a subsequent optimization.

1044 Image_Enumeration_16, Image_Enumeration_32): Define the index of
1045 Index_Table with range Natural'First .. Names'Length since in
1046 the worst case all the literals of the enumeration type would be
1047 single letter literals and the Table built by the frontend would
1048 have as many components as the length of the names string. As a
1049 result of this enhancement, the internal tables declared using
1050 Index_Table have a length closer to the real needs, thus
1051 avoiding the declaration of large arrays on 32-bit CCG targets.

1088 * sem_ch3.adb (Convert_Bound): Subsidiary of
1089 Floating_Point_Type_Declaration, to handle properly range
