Stderr_File): Close local file descriptors when no longer needed.
2016-04-18 Ed Schonberg <schonberg@adacore.com>
* sem_ch5.adb (Analyze_Iterator_Specification): Remove SPARK
mode check that the type of the cursor in an iteration over
a formal container is not volatile. The proper check on the
element type is done elsewhere.
2016-04-18 Ed Schonberg <schonberg@adacore.com>
* sem_ch6.adb (Process_Formals): Do not set a delay freeze on
a subprogram that returns a class-wide type, if the subprogram
is a compilation unit, because otherwise gigi will treat the
subprogram as external, leading to link errors.

2016-04-18 Yannick Moy <moy@adacore.com>
* checks.adb (Apply_Scalar_Range_Check): Force
warning instead of error when SPARK_Mode is On, on index out of

* sem_prag.adb (Check_In_Out_States.Check_Constituent_Usage):
Update the comment on usage. Reimplemented.
(Check_Input_States.Check_Constituent_Usage): Update the comment

2016-04-18 Ed Schonberg <schonberg@adacore.com>
* sem_ch6.adb (Check_Inline_Pragma): Use the Sloc of the
body id as the sloc of the entity in the generated subprogram
declaration, to avoid spurious conformance errors when style
checks are enabled.
* 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.
* sem_prag.adb (Check_Arg_Is_Local_Name): Don't do the check
if the pragma came from an aspect specification.
2016-04-18 Gary Dismukes <dismukes@adacore.com>
* 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.
* lib-xref-spark_specific.adb, par-ch2.adb, errout.ads,
exp_intr.adb: Minor reformatting and typo corrections.
2016-04-18 Ed Schonberg <schonberg@adacore.com>
* sem_ch6.adb: Code cleanup.
2016-04-18 Thomas Quinot <quinot@adacore.com>

2016-04-18 Johannes Kanig <kanig@adacore.com>
* gnat1drv.adb (Gnat1drv): Force loading of System unit for SPARK.
2016-04-18 Bob Duff <duff@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.
* 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):

* sem_prag.adb (Analyze_Pragma): Check restriction
No_Use_Of_Pragma before any rewritings have taken place.
* tree-ssa-pre.c (postorder, postorder_num): Make locals ...

postorder and scrap iteration.
(compute_partial_antic_aux): Remove unused return value.
(init_pre): Do not allocate postorder.
(fini_pre): Do not free postorder.
* 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.

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.
* 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.
* 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.
* 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.
* 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.
* 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.
* 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>

* 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.
* 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>

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>

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

* targparm.ads: Update the Frontend_Exceptions default internal
value.
(Frontend_Exceptions_On_Target): Change default value to True.
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.
* sem_ch3.adb (Analyze_Object_Declaration): Do not consider
internally generated expressions when trying to determine whether
a formal parameter of a tagged type subject to Extensions_Visible
False is used to initialize an object.

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.

from contracts.adb (Replace_Condition_Entities): Subsidiary
Build_Pragma_Check_Equivalent, to implement the proper semantics
of inherited class-wide conditions, as given in AI12-0113.

errors to call Cannot_Inline instead, which does appropriate
processing of message for GNATprove.

body to inline in GNATprove mode when SPARK_Mode On applies to
subprogram body.
* sem_prag.adb, sem_prag.ads (Get_SPARK_Mode_Type): Make function

* sem_disp.adb (Check_Dispatching_Call): Major rewriting to
handle some complex cases of tag indeterminate calls that are
actuals in other dispatching calls that are themselves tag
indeterminate.
(Check_Dispatching_Context): Add parameter to support recursive
check for an enclosing construct that may provide a tag for a
tag-indeterminate call.
* sem_prag.adb (Analyze_Depends_In_Decl_Part):
Add global variables Task_Input_Seen and Task_Output_Seen.
(Analyze_Global_Item): Detect an illegal use of the current

(Is_CCT_Instance): New parameter profile. Update
the comment on usage. The routine now properly recognizes several
cases related to single protected/task types.

sigtramp-vxworks.c (__gnat_sigtramp) Take into account the
differences in the sigcontext structure between the expected
regular x86 or x86_64 ones and the ones received in case of
exexution on the vxworks simulator.
* init.c: also compute is_vxsim in case of x86_64-vx7 target. Provide
this information to sigtramp-vxworks.c. Remove the old mechanism for
vxsim.

2016-04-18 Eric Botcazou <ebotcazou@adacore.com>
* exp_ch3.adb (Inline_Init_Proc): New function returning

* sem_util.adb (Is_Current_Instance): A entity given by a subtype
declaration can appear in an aspect specification for a dynamic
predicate, and a pragma for aspect Predicate_Failure.

occurrences of the subtype to which a dynamic predicate applies,
byt the expression that triggers a predicate check. Needed to
implement new aspect Predicate_Failure.
* 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.
We didn't have __builtin_swap16 on all targets before GCC 4.8; hsa-brig
tries to use it if the host GCC is 4.6 or up though, breaking bootstrap.
This trivial patch fixes it.
