-2017-09-08 Ed Schonberg <schonberg@adacore.com>
-
- * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
- check if the instance is within an enclosing instance body. The
- formal package was legal in the enclosing generic, and is
- legal in the enclosing instantiation. This optimisation may be
- applicable elsewhere, and it also removes spurious errors that
- may arise with on-the-fly processing of instantiations that
- contain Inline_Always subprograms.

-
-2017-09-08 Arnaud Charlet <charlet@adacore.com>
-
- * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
- sem_prag.adb to make it available for GNATprove; for concurrent
- types replace custom scope climbing with Scope_Same_Or_Within; for
- single concurrent objects add scope climbing (with Scope_Within),
- which was not there (that's the primary semantic change of this
- commit); also, when comparing a single concurrent object with
- its corresponding concurrent type rely on equality of types,
- not of objects (because that's simpler to code).
- * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
- (Analyze_Global_Item): adjust special-casing of references to the
- current instance of a concurrent unit in the Global contracts
- of task types and single tasks objects; similar for references
- in the protected operations and entries of protected types and
- single protected objects (in all these cases the current instance
- behaves as an implicit parameter and must not be mentioned in
- the Global contract).

- * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
- entity of a mutable type and the right-hand side is a conditional
- expression, resolve the alternatives of the conditional using

-
- * checks.adb (Apply_Predicate_Check): If the expression is an
- aggregate that is the RHS of an assignment, apply the check to
- the LHS after the assignment, rather than to the aggregate. This
- is more efficient than creating a temporary for the aggregate,

- Get rid of Orig_Nodes_...; use Node_... instead.

- * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
- checking, for source buffers. Modify representation clause for
- Source_File_Record as appropriate. Move Source_File_Index_Table
- from spec to body, because it is not used outside the body.

- it is used only in the body and in children. Use trickery to

- legacy condition for separate units, remove dispatching for ASIS
- and save a copy of the expression in the pragma expression.

- remove return condition on interfaces, always use the
- private type for interfaces, and move the processing of types
- until after the processing of invariants for the full view.
- (Build_Invariant_Procedure_Declaration): Remove condition
- to return if an interface type is encountered and add
- condition to convert the formal parameter to its class-wide
- counterpart if Work_Typ is abstract.

- (Replace_Type_Ref): Remove class-wide dispatching for the current
- instance of the type.

- the controlliong argument from calls to primitives in the case
- of the formal parameter being an class-wide abstract type.

- to the change made to Freeze_Type in exp_ch3. Add a condition
- to treat interface types as a partial view.
- * sem_prag.adb (Analyze_Pragma): Modify parameters in the call
- to Build_Invariant_Procedure_Declaration to properly generate a
- "partial" invariant procedure when Typ is an interface.

-2017-04-25 Ed Schonberg <schonberg@adacore.com>
-
- * sem_ch3.adb (Derive_Subprogram): Implement rule in RM 6.1.1
- (10-15): if derived type T with progenitors is abstract,
- and primitive P of this type inherits non-trivial classwide
- preconditions from both a parent operation and from an interface

-
- * a-numeri.ads: Change the encoding of Greek letter Pi from
- brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
- to indicate the encoding. We considered using a byte order mark
- (BOM), but that causes various trouble (misc software eats the
- BOM, if you have a patch with a BOM, then it's not at the start
- of the patch, so it's not a BOM, the BOM affects with-ing files,

-
-2017-04-25 Bob Duff <duff@adacore.com>
-
- * sem_prag.adb (No_Return): Give an error if the pragma applies
- to a body. Specialize the error for the specless body case,
- as is done for (e.g.) pragma Convention.
- * debug.adb: Add switch -gnatd.J to disable the above legality
- checks. This is mainly for use in our test suite, to avoid
- rewriting a lot of illegal (but working) code. It might also
- be useful to customers. Under this switch, if a pragma No_Return
- applies to a body, and the procedure raises an exception (as it
- should), the pragma has no effect. If the procedure does return,
- execution is erroneous.
-
-2017-04-25 Bob Duff <duff@adacore.com>
-
- * exp_ch6.adb (Expand_Actuals): This is the
- root of the problem. It took N as an 'in out' parameter, and in
- some cases, rewrote N, but then set N to Original_Node(N). So
- the node returned in N had no Parent. The caller continued
- processing of this orphaned node. In some cases that caused a
- crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
- and trips over the Empty Parent). The solution is to make N an
- 'in' parameter. Instead of rewriting it, return the list of
- post-call actions, so the caller can do the rewriting later,
- after N has been fully processed.
- (Expand_Call_Helper): Move most of Expand_Call here. It has
- too many premature 'return' statements, and we want to do the
- rewriting on return.
- (Insert_Post_Call_Actions): New procedure to insert the post-call
- actions in the appropriate place. In the problematic case,
- that involves rewriting N as an Expression_With_Actions.
- (Expand_Call): Call the new procedures Expand_Call_Helper and
- Insert_Post_Call_Actions.

- (Temp_File_Record): Add File

- to the file being closed.
- (Delete): Don't delete temp files,

+
+2017-09-08 Ed Schonberg <schonberg@adacore.com>
+
+ * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
+ check if the instance is within an enclosing instance body. The
+ formal package was legal in the enclosing generic, and is
+ legal in the enclosing instantiation. This optimisation may be
+ applicable elsewhere, and it also removes spurious errors that
+ may arise with on-the-fly processing of instantiations that
+ contain Inline_Always subprograms.

+
+2017-09-08 Yannick Moy <moy@adacore.com>

+
+2017-04-25 Bob Duff <duff@adacore.com>
+
+ * exp_ch6.adb (Expand_Actuals): This is the
+ root of the problem. It took N as an 'in out' parameter, and in
+ some cases, rewrote N, but then set N to Original_Node(N). So
+ the node returned in N had no Parent. The caller continued
+ processing of this orphaned node. In some cases that caused a
+ crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
+ and trips over the Empty Parent). The solution is to make N an
+ 'in' parameter. Instead of rewriting it, return the list of
+ post-call actions, so the caller can do the rewriting later,
+ after N has been fully processed.
+ (Expand_Call_Helper): Move most of Expand_Call here. It has
+ too many premature 'return' statements, and we want to do the
+ rewriting on return.
+ (Insert_Post_Call_Actions): New procedure to insert the post-call

+ (Expand_Call): Call the new procedures Expand_Call_Helper and
+ Insert_Post_Call_Actions.
