- (Check_Interfaces): Default initialize Full_T_Ifaces and Priv_T_Ifaces,
- which seem to be left uninitialized and possibly read in some cases.

- precisely. This requires to exchange the test for exiting in case of
- too many positions and the increment to Position, inside the loop.

- exercized (it depends on the presence of an extension of System).
- * sem_spark.ads: Update comment to fix name of main analysis procedure.
- * sem_warn.adb (Warn_On_Known_Condition): Default initialize
- Test_Result.
- * set_targ.adb (FailN): Mark procedure with No_Return.

-
-2017-11-09 Bob Duff <duff@adacore.com>
-
- * namet.ads, namet.adb (Valid_Name_Id): New subtype that excludes
- Error_Name and No_Name. Use this (versus Name_Id) to indicate which
- objects can have those special values. Valid_Name_Id could usefully be
- used all over the compiler front end, but that's too much trouble for
- now. If we did that, we might want to rename:
- Name_Id --> Optional_Name_Id, Valid_Name_Id --> Name_Id.
- For parameters of type Valid_Name_Id, remove some redundant tests,
- including the ones found by CodePeer. Use Is_Valid_Name instead of
- membership test when appropriate.
- (Error_Name_Or_No_Name): Delete this; it's no longer needed.
- * sem_ch2.adb (Analyze_Identifier): Use "not Is_Valid_Name" instead of
- "in Error_Name_Or_No_Name".
- (Check_Parameterless_Call): Use "not Is_Valid_Name" instead of "in

- (Add_Interface_Invariatns),
- (Add_Parent_Invariants): Modify call to Add_Inherited_Invariants
- to including the working type T.
- (Add_Own_Invariants): Remove
- 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): Add call to Remove_Controlling_Arguments.
- (Replace_Type_Ref): Remove class-wide dispatching for the current
- instance of the type.
- (Replace_Type_References): Remove parameter "Derived"
- (Remove_Controlling_Arguments): Created in order to removing
- the controlliong argument from calls to primitives in the case
- of the formal parameter being an class-wide abstract type.
- * sem_ch3.adb (Build_Assertion_Bodies_For_Type): Almost identical
- 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.

- letter pi.
-
-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
- operation, then the inherited operation is abstract if the parent
- operation is not null.

- attribute types with the same designated type keep either of
- them and do not report an ambiguity. A true ambiguity will be
- reported elsewhere.

-2017-04-25 Bob Duff <duff@adacore.com>
-
- * 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,
- etc.).
- * scng.adb, s-wchcnv.adb: Minor.

-
-2017-04-25 Olivier Hainque <hainque@adacore.com>
-

- specs without elaboration code that have an elaboration counter
- nevertheless, e.g. when compiled with -fpreserve-control-flow.
- * sem_ch10.adb (Analyze_Compilation_Unit):
- Set_Elaboration_Entity_Required when requested to preserve
- control flow, to ensure the unit elaboration is materialized at

- in the executable closure at link time.
-
-2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
-
- * exp_dbug.adb: In Debug_Renaming_Declaration,
- when dealing with indexed component, accept to produce a renaming

- defined in an outer scope.
-
-2017-04-25 Yannick Moy <moy@adacore.com>

- Minor reformatting.
-
-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.

-
- * exp_unst.adb (Subp_Index): Adding missing
- support for renamings and functions that return a constrained

-2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
-
- * sem_ch4.adb: sem_ch4.adb Various reformattings.

-2017-04-25 Bob Duff <duff@adacore.com>
-
- * s-fileio.adb (Close): When a temp file is
- closed, delete it and clean up its Temp_File_Record immediately,
- rather than waiting until later.
- (Temp_File_Record): Add File
- component, so Close can know which Temp_File_Record corresponds
- to the file being closed.
- (Delete): Don't delete temp files,
- because they are deleted by Close.
- (Open): Set the File component
- of Temp_File_Record. This requires moving the creation of the
- Temp_File_Record to the end, after the AFCB has been created.

- * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
- to Is_Predefined_Unit_Name; the former was wrong, because Uname
- is not a file name at all.
- * fname.ads, fname.adb: Document the fact that
