* sem_attr.adb (Analyze_Attribute_Old_Result): The attributes can
appear in the postcondition of a subprogram renaming declaration,
when the renamed entity is an attribute reference that is a
function (such as 'Value).
* sem_attr.adb (Eval_Attribute): It doesn't
need to be static, just known at compile time, so use
Compile_Time_Known_Value instead of Is_Static_Expression.
This is an efficiency improvement over the previous bug fix.
* sem_ch13.adb (Analyze_One_Aspect): Use Original_Node to detect
illegal aspects on subprogram renaming declarations that may
have been rewritten as bodies.

folded. Fix it so it makes that assumption only when X denotes
a STATIC constant.

* sem_elim.adb (Line_Num_Match): Moved redundant condition
"Sloc_Trace (Idx) = '['" to an Assert.

the "?" is quoted, as in "'?", so we want to check the PREVIOUS

2016-04-18 Bob Duff <duff@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
"r+". This is necessary to make a write to the fifo block until
a reader is ready.
2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
* sem_attr.adb (Denote_Same_Function): Account
for a special case where a primitive of a tagged type inherits
a class-wide postcondition from a parent type.
2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
* 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.
(Set_Restriction_No_Specification_Of_Aspect): Properly set the warning
flag for an aspect.
(Set_Restriction_No_Use_Of_Attribute): Properly set the warning
flag for an attribute. (Set_Restriction_No_Use_Of_Entity):
Update the parameter profile.
(Set_Restriction_No_Use_Of_Pragma): Properly set the warning flag for
a pragma.
* restrict.ads (Check_Restriction_No_Use_Of_Attribute): Update
the comment on usage.
(Set_Restriction_No_Use_Of_Entity): Update the parameter profile.
* sem_attr.adb (Analyze_Attribute): Check restriction
No_Use_Of_Attribute.
* sem_ch13.adb (Analyze_Attribute_Definition_Clause): Check
restriction No_Use_Of_Attribute before any rewritings have
taken place.
* sem_prag.adb (Analyze_Pragma): Check restriction
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
parameter, defaulting to Global_Name_Buffer.
* errout.ads, errout.adb (Adjust_Name_Case): Pass a
Bounded_String parameter, no default.
* exp_ch11.adb (Expand_N_Raise_Statement): Use local
Bounded_String instead of Global_Name_Buffer.
* exp_intr.ads, exp_intr.adb (Write_Entity_Name): Rename it
to Append_Entity_Name, and pass a Bounded_String parameter,
instead of using globals.
(Add_Source_Info): Pass a Bounded_String parameter, instead of
using globals.
(Expand_Source_Info): Use local instead of globals.
* stringt.ads, stringt.adb (Append): Add an Append procedure
for appending a String_Id onto a Bounded_String.
(String_To_Name_Buffer, Add_String_To_Name_Buffer): Rewrite in
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.
* lib-xref-spark_specific.adb (Add_SPARK_Scope): Pretend that calls to
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 Hristian Kirtchev <kirtchev@adacore.com>
* stringt.adb, exp_ch6.adb, sem_ch13.adb: Minor reformatting.
2016-04-18 Gary Dismukes <dismukes@adacore.com>
* par-ch4.adb, sem_prag.adb: Minor reformatting.
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>
* namet.adb, namet.ads, exp_unst.adb: Minor reformatting.
2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
* sem_eval.adb (Choice_Matches): Check the expression
against the predicate values when the choice denotes a
subtype with a static predicate.
(Eval_Membership_Op): Code cleanup. Remove the suspicious guard which
tests for predicates.
(Is_OK_Static_Subtype): A subtype with a dynamic predicate
is not static. (Is_Static_Subtype): A subtype with a dynamic
predicate is not static.
* sem_eval.ads (Is_OK_Static_Subtype): Update the comment on usage.
(Is_Static_Subtype): Update the comment on usage.
2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
* sem_prag.adb (Analyze_Input_Item): Allow
generic formals to appear as initialization items.
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>
* exp_ch5.adb (Expand_Assignment_Statement): In restricted
profiles such as ZFP, ceiling priority is not available.
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
outside of GNATprove, hence it should not be removed.
2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
* sem_prag.adb (Analyze_Refinement_Clause):
The refinement of an external abstract state can now mention
non-external constituents.
(Check_External_Property): Update all SPARK RM references.
2016-04-18 Bob Duff <duff@adacore.com>
* exp_intr.adb: Remove some duplicated code.

* gnat1drv.adb (Gnat1drv): Force loading of System
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 Yannick Moy <moy@adacore.com>

Analyze_Protected_Contract): Remove tests performed in GNATprove.
* sem_util.adb, sem_util.ads (Has_Full_Default_Initialization):
Remove query for tests performed in GNATprove.
2016-04-18 Ed Schonberg <schonberg@adacore.com>
* sem_aggr.adb (Resolve_Record_Aggregate): If
Warn_On_Redundant_Constructs is enabled, report a redundant box
association that does not cover any components, as it done for
redundant others associations in case statements.
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
that it does not freeze the dispatching type of the primitive
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).
2016-04-18 Vincent Celier <celier@adacore.com>
* ali.ads: Increase the range of all _Id types to 100 millions.
2016-04-18 Gary Dismukes <dismukes@adacore.com>

2016-04-18 Eric Botcazou <ebotcazou@adacore.com>
* layout.adb (Set_Elem_Alignment): Extend setting of alignment
to subtypes that are not first subtypes.
2016-04-18 Ed Schonberg <schonberg@adacore.com>
* sem_prag.ads (Collect_Inherited_Class_Wide_Conditions):
Simplify interface.
* sem_prag.adb (Collect_Inherited_Class_Wide_Conditions): Insert
generated pragmas after subprogram declaration, rather than in
the corresponding subprogram body.
* sem_ch6.adb (New_Overloaded_Entity): In GNATProve
mode, if the operation is overridding, call
Collect_Inherited_Class_Wide_Conditions to generate the
corresponding pragmas immediately after the corresponding
subprogram declaration.
2016-04-18 Arnaud Charlet <charlet@adacore.com>
* spark_xrefs.ads (Xref_Index, Scope_Index, File_Index): restrict
type to natural numbers.

2016-04-18 Ed Schonberg <schonberg@adacore.com>
* sem_ch4.adb (Analyze_Selected_Component): Refine error
detection when a selected component in the body of a synchronized
type is a reference to an object of the same type declared
elsewhere. The construct is legal if the prefix of the selected
component includes an explicit dereference at any point.
2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
* sem_ch3.adb (Analyze_Object_Declaration): Do not consider
internally generated expressions when trying to determine whether

internally generated expressions when trying to determine whether
a formal parameter of a tagged type subject to Extensions_Visible
False is used in a type conversion.

Add guards to account for a non-decorated selected component.
2016-04-18 Yannick Moy <moy@adacore.com>

New function replacing previous Get_SPARK_Mode_From_Pragma, that
deals also with aspects.
(Get_SPARK_Mode_Type): Make function internal again.
* inline.adb, sem_ch7.adb, sem_util.adb: Use new
Get_SPARK_Mode_From_Annotation.

of a tagged type and its primitive agree.
* sem_prag.adb (Analyze_Pragma): Update references to SPARK
RM. Move the verification of pragma Assertion_Policy Ghost
to the proper place. Remove the now obsolete check related
to Ghost derivations.
(Collect_Constituent): Add a call to Check_Ghost_Refinement.

declaration can appear in an aspect specification for a dynamic
predicate, and a pragma for aspect Predicate_Failure.
* exp_util.adb (Replace_Subtype_References): Replace current

byt the expression that triggers a predicate check. Needed to
implement new aspect Predicate_Failure.

2016-04-18 Jerome Lambourg <lambourg@adacore.com>
* sigtramp-vxworks-target.inc: sigtramp-vxworks: force the stack
alignment for x86_64.
* init.c: Better fix for guard page reset on x86_64-vx7.
Do not try to retrieve the page that actually raised
the signal as the probing mechanism used on x86_64 do not allow
such retrieval. We thus just test if the guard page is active,
and re-activate it if not.
2016-04-18 Arnaud Charlet <charlet@adacore.com>
