-2016-04-18 Ed Schonberg <schonberg@adacore.com>
-
- * sem_ch6.adb (Check_Inline_Pragma): Use the Sloc of the

- declaration, to avoid spurious conformance errors when style
- checks are enabled.
-
-2016-04-18 Ed Schonberg <schonberg@adacore.com>
-
- * sem_ch4.adb (Analyze_Selected_Component, Has_Dereference):
- Refine check on illegal calls to entities within a task body,
- when the entity is declared in an object of the same type. In
- a generic context there might be no explicit dereference but if
- the prefix includes an access type the construct is legal.
-

-
- * gnat1drv.adb, contracts.adb: Minor reformatting and wording fixes.
-
-2016-04-18 Ed Schonberg <schonberg@adacore.com>
-
- * sem_ch6.adb (Analyze_Subprogram_Body_Helper): To suppress
- superfluous conformance check on an inlined body with a previous
- spec, use the fact that the generated declaration does not come
- from source. We must treat the entity as coming from source to
- enable some back-end inlining when pragma appears after the body.
-
-2016-04-18 Gary Dismukes <dismukes@adacore.com>

-
- * s-fileio.adb (Fopen_Mode): If Mode = Out_File, and the file
- exists, and it's a fifo, we use "w" as the open string instead of

-
- * par-ch2.adb (P_Expression_Or_Reserved_Word): New routine.
- (P_Pragma): Signal Scan_Pragma_Argument_Association when the use
- of reserved words is OK.
- (Scan_Pragma_Argument_Association):
- Add new formal Reserved_Words_OK and update the comment on
- usage. Code cleanup. Parse an expression or a reserved word in
- identifier form for pragmas Restriction_Warnings and Restrictions
- No_Use_Of_Attribute.
- * restrict.adb (Check_Restriction_No_Use_Of_Attribute):
- Reimplemented. (Check_Restriction_No_Use_Of_Pragma): Code cleanup.

- No_Use_Of_Pragma before any rewritings have taken place.
-
-2016-04-18 Bob Duff <duff@adacore.com>
-
- * sem_ch6.adb (Is_Inline_Pragma): The pragma
- argument can be a selected component, which has no Chars field,
- so we need to deal with that case (use the Selector_Name).
- (Check_Inline_Pragma): We need to test Is_List_Member before
- calling In_Same_List, because in case of a library unit, they're
- not in lists, so In_Same_List fails an assertion.
-
-2016-04-18 Bob Duff <duff@adacore.com>
-
- * namet.ads, namet.adb: Add an Append that appends a
- Bounded_String onto a Bounded_String. Probably a little more
- efficient than "Append(X, +Y);". Also minor cleanup.
- (Append_Decoded, Append_Decoded_With_Brackets, Append_Unqualified,
- Append_Unqualified_Decoded): Make sure these work with non-empty
- buffers.
- * casing.ads, casing.adb (Set_Casing): Pass a Bounded_String

- terms of Append.
- * sem_prag.adb (Set_Error_Msg_To_Profile_Name): Adjust for new
- Adjust_Name_Case parameter.
- * erroutc.adb, uname.adb: Don't pass D => Mixed_Case to
- Set_Casing; that's the default.

- protected subprograms are entry calls; otherwise it is not possible to
- distinguish them from regular subprogram calls.
-
-2016-04-18 Gary Dismukes <dismukes@adacore.com>
-
- * sem_ch13.adb (Has_Good_Profile): Improvement
- of error message. Now indicates subtype_mark of formal parameter
- rather than the formal's name, plus minor rewording.
-
-2016-04-18 Pascal Obry <obry@adacore.com>
-
- * adaint.c, adaint.h, s-os_lib.ads: Add new routine Current_Process_Id.

-
-2016-04-18 Bob Duff <duff@adacore.com>
-
- * sinput.ads, sinput.adb (Build_Location_String): Take a
- parameter instead of using a global variable. The function
- version no longer destroys the Name_Buffer.
- * stringt.ads, stringt.adb (String_From_Name_Buffer): Take a
- parameter, which defaults to the Global_Name_Buffer, so some
- calls can avoid the global.
- * exp_ch11.adb, exp_intr.adb: Use new interfaces above
- to avoid using globals. All but one call to Build_Location_String
- avoids the global. Only one call to String_From_Name_Buffer
- avoids it.
-
-2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>

-2016-04-18 Ed Schonberg <schonberg@adacore.com>
-
- * sem_ch13.adb (Analyze_Stream_TSS_Definition,
- Has_Good_Profile): Additional error message to indicate that
- the second parameter of the subprogram must be a first subtype.
-
-2016-04-18 Ed Schonberg <schonberg@adacore.com>
-
- * sem_ch6.adb (Analyze_Subprogram_Body_Helper, Is_Inline_Pragma):
- Use the pragma lookahead that determines whether a subprogram
- is to be inlined, when some level of backend optimization is
- required.
- * sem_ch12.ads, sem_ch12.adb (Add_Pending_Instantiation): Factorize
- code used to create an instance body when needed for inlining.
- * exp_ch6.adb (Expand_Call): When a call is to be inlined, and the
- call appears within an instantiation that is not a compilation
- unit, add a pending instantiation for the enclosing instance,
- so the backend can inline in turn the calls contained in the
- inlined body.
-
-2016-04-18 Ed Schonberg <schonberg@adacore.com>
-
- * sem_prag.adb (Build_Pragma_Check_Equivalent): The mapping
- that relates operations of the parent type to the operations of
- the derived type has three distinct sources:
- a) explicit operations of the derived type carry an
- Overridden_Operation that designates the operation in the
- ancestor.
- b) Implicit operations that are inherited by the derived type
- carry an alias that may be an explicit subprogram (in which case
- it may have an Overridden_ Operation indicator) or may also be
- inherited and carry its own alias.
- c) If the parent type is an interface, the operation of the
- derived type does not override, but the interface operation
- indicates the operation that implements it.
- * sem_prag.adb: Minor reformatting.
- * sem_prag.adb (Check_External_Property): Update
- the comment on usage. Reimplement.
-
-2016-04-18 Ed Schonberg <schonberg@adacore.com>

-2016-04-18 Bob Duff <duff@adacore.com>
-
- * namet-sp.ads: Minor typo fix, ironically in 'Spelling_Checker'.
-
-2016-04-18 Bob Duff <duff@adacore.com>
-
- * sem_elab.adb (Output_Calls): Use
- Get_Name_String, to clearly indicate that the global Name_Buffer
- is being used. The previous code used Is_Internal_Name, which
- returns a Boolean, but also has a side effect of setting the
- Name_Buffer. Then it called the other Is_Internal_Name, which uses
- the Name_Buffer for its input. And then it called Error_Msg_N,
- again using the Name_Buffer. We haven't eliminated the global
- usage here, but we've made it a bit clearer.
- This also allows us to have a side-effect-free version of
- Is_Internal_Name.
- * namet.ads, namet.adb: Provide a type Bounded_String, along with
- routines that can be used without using global variables. Provide
- Global_Name_Buffer so existing code can continue to use the
- global. Mark the routines that use globals as obsolete. New code
- shouldn't call the obsolete ones, and we should clean up existing
- code from time to time.
- Name_Find_Str is renamed as Name_Find.
- * namet.h: Changed as necessary to interface to the new version
- of Namet.
- * bindgen.adb, exp_unst.adb: Name_Find_Str is renamed as
- Name_Find.
-
-2016-04-18 Yannick Moy <moy@adacore.com>
-
- * sem_util.adb, sem_util.ads (Has_Full_Default_Initialization): used

- unit for SPARK.
-
-2016-04-18 Bob Duff <duff@adacore.com>
-
- * a-cuprqu.adb: Correction to previous change. If a new node
- is inserted at the front of the queue (because it is higher
- priority than the previous front node), we need to update
- Header.Next_Unequal -- not just in the case where the queue was
- previously empty.
-
-2016-04-18 Bob Duff <duff@adacore.com>
-
- * a-cuprqu.ads: Change the representation of List_Type from a
- singly-linked list to a doubly-linked list. In addition, add a
- pointer Next_Unequal, which points past a possibly-long chain
- of equal-priority items. This increases efficiency, especially
- in the case of many equal-priority items.
- * a-cuprqu.adb (Dequeue, Enqueue): Rewrite algorithms to take
- advantage of new data structure.
- (Finalize): Rewrite in terms of Dequeue, for simplicity.

-
-2016-04-18 Ed Schonberg <schonberg@adacore.com>
-
- * sem_prag.adb (Collect_Inherited_Class_Wide_Conditions):
- Analyze the generated Check pragma for an inherited condition so

- operation, because it is pre-analyzed at the point of the
- subprogram declaration (and not in the subprogram body, as is
- done during regular expansion).

+
+ * sem_elab.adb (Output_Calls): Use
+ Get_Name_String, to clearly indicate that the global Name_Buffer
+ is being used. The previous code used Is_Internal_Name, which
+ returns a Boolean, but also has a side effect of setting the
+ Name_Buffer. Then it called the other Is_Internal_Name, which uses
+ the Name_Buffer for its input. And then it called Error_Msg_N,
+ again using the Name_Buffer. We haven't eliminated the global
+ usage here, but we've made it a bit clearer.
+ This also allows us to have a side-effect-free version of
+ Is_Internal_Name.
+ * namet.ads, namet.adb: Provide a type Bounded_String, along with
+ routines that can be used without using global variables. Provide
+ Global_Name_Buffer so existing code can continue to use the
+ global. Mark the routines that use globals as obsolete. New code
+ shouldn't call the obsolete ones, and we should clean up existing
+ code from time to time.
+ Name_Find_Str is renamed as Name_Find.
+ * namet.h: Changed as necessary to interface to the new version
+ of Namet.
