Ifaces_Comp_List.
2017-11-09 Pascal Obry <obry@adacore.com>
* libgnarl/s-taprop__mingw.adb: On Windows, initialize the thead handle
only for foreign threads. We initialize the thread handle only if not
yet initialized. This happens in Enter_Task for foreign threads only.
But for native threads (Ada tasking) we do want to keep the real
handle (from Create_Task) to be able to free the corresponding
resources in Finalize_TCB (CloseHandle).
2017-11-09 Yannick Moy <moy@adacore.com>
* sem_attr.adb (Analyze_Attribute): Default initialize P_Type,
P_Base_Type.

* sem_aggr.adb (Resolve_Delta_Record_Aggregate): Reorder declarations
to avoid a dormant bug.
2017-11-09 Jerome Lambourg <lambourg@adacore.com>
* init.c: Define missing __gnat_alternate_stack for QNX. Set it to 0,
as such capability is not available on the OS.
* link.c: Make sure linker options for QNX are correct.
* libgnarl/s-osinte__qnx.ads: Add some missing bindings to pthread.
* libgnarl/s-taprop__qnx.adb: New, derived from s-taprop__posix.adb. This brings
in particular a workaround with locks priority ceiling where a higher
priority task is allowed to lock a lower ceiling priority lock. This
also fixes the scheduling of FIFO tasks when the priority of a task is
lowered.
* libgnat/system-qnx-aarch64.ads: Fix priority ranges.
2017-11-09 Yannick Moy <moy@adacore.com>

condition.

are symbols in the table depends on a global invariant at this point in
the program.
* set_targ.adb (Check_Spaces): Justify CodePeer false positive message.
* stylesw.adb (Save_Style_Check_Options): Rewrite to avoid test always
true.
2017-11-09 Javier Miranda <miranda@adacore.com>

(Building_Static_Secondary_DT): Check restriction.
(Make_DT): Initialize the HT_Link to No_Tag.

remove pragma Warnings(Off).
* exp_imgv.adb (Expand_Image_Attribute): Default initialize Tent.
* exp_util.adb (Find_Interface_Tag): Default initialize AI_Tag.
* freeze.adb (Check_Component_Storage_Order): Default initialize
Comp_Byte_Aligned rather than silencing messages with pragma
Warnings(Off), which does not work for CodePeer initialization
messages, and given that here the possible read of an unitialized value
depends on a proper use of parameters by the caller.
* inline.adb (Expand_Inlined_Call): Default initialize Lab_Decl, Targ.
* sem_ch12.adb (Build_Operator_Wrapper): Default initialize Expr.
* sem_ch3.adb (Build_Derived_Array_Type): Default initialize
Implicit_Base.
* sem_ch4.adb (List_Operand_Interps): Default initialize Nam and remove
pragma Warnings(Off).
(Analyze_Case_Expression): Rescope checking block within branch where
Others_Present is set by the call to Check_Choices.
* sem_ch5.adb (Analyze_Assignment): Default initialize
Save_Full_Analysis.
* sem_ch6.adb (Analyze_Function_Return): Default initialize Obj_Decl,
and restructure code to defend against previous errors, so that, in
that case, control does not flow to the elsif condition which read an
uninitialized Obj_Decl.
* sem_ch9.adb (Analyze_Requeue): Default initialize Synch_Type.
(Check_Interfaces): Default initialize Full_T_Ifaces and Priv_T_Ifaces,
which seem to be left uninitialized and possibly read in some cases.
* sem_dim.adb (Analyze_Aspect_Dimension_System): Retype Position more
precisely. This requires to exchange the test for exiting in case of
too many positions and the increment to Position, inside the loop.
* sem_eval.adb (Eval_Concatenation): Default initialize Folded_Val,
which cannot be read uninitialized, but the reasons for that are quite
subtle.
* sem_intr.adb (Check_Intrinsic_Call): Default initialize Rtyp.
* sem_prag.adb (Collect_Subprogram_Inputs_Outputs): Default initialize
Spec_Id.
* sem_res.adb (Make_Call_Into_Operator): Default initialize Opnd_Type,
and test for presence of non-null Opnd_Type before testing its scope,
in a test which would read its value uninitialized, and is very rarely
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.
* stylesw.adb (Save_Style_Check_Options): Delete useless code to
initialize all array Options to white space, as there is already code
doing the same for the remaining positions in Options at the end of the
procedure.
2017-11-09 Eric Botcazou <ebotcazou@adacore.com>
* exp_ch11.adb (Possible_Local_Raise): Do not issue the warning for
generic instantiations either.

* sem_prag.adb (Analyze_Part_Of): Reword error message.
(Get_SPARK_Mode_Type): Do not raise Program_Error in case pragma

mode.
2017-11-09 Ed Schonberg <schonberg@adacore.com>
* sem_ch4.adb (Analyze_Call): Reject a call to a function that returns
a limited view of a type T declared in unit U1, when the function is
declared in another unit U2 and the call appears in a procedure within
another unit.
2017-11-09 Justin Squirek <squirek@adacore.com>
* sem_ch8.adb (Analyze_Use_Package): Force installation of use_clauses
when processing generic instances.
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
Error_Name_Or_No_Name".
2017-11-09 Arnaud Charlet <charlet@adacore.com>
* gnat1drv.adb (Adjust_Global_Switches): Suppress warnings in codepeer
mode here unless -gnateC is specified.
* switch-c.adb (Scan_Front_End_Switches): Do not suppress warnings with
-gnatC here.
2017-11-09 Piotr Trojanek <trojanek@adacore.com>
* lib-writ.adb (Write_ALI): Remove processing of the frontend xrefs as
part of the ALI writing; they are now processed directly from memory
when requested by the backend.
* lib-xref.ads (Collect_SPARK_Xrefs): Remove.
(Iterate_SPARK_Xrefs): New routine for iterating over frontend xrefs.
* lib-xref-spark_specific.adb (Traverse_Compilation_Unit): Remove.

2017-11-09 Ed Schonberg <schonberg@adacore.com>
* sem_res.adb (Resolve): If expression is an entity whose type has
implicit dereference, generate reference to it, because no reference is
generated for an overloaded entity during analysis, given that its
identity may not be known.

an addition since the offset-to-top field is now a negative value.
(Displace): Displace the pointer to the object means of a substraction
since it is now a negative value.
(Set_Dynamic_Offset_to_top): Displace the pointer to the object by
means of a substraction since it is now a negative value.

the Class Level): Fix error interfacing with C strings.

the type of the renaming from its defining entity, rather then the
subtype mark as there may not be a subtype mark.
2017-11-08 Jerome Lambourg <lambourg@adacore.com>
* adaint.c, s-oscons-tmplt.c, init.c, libgnat/system-qnx-aarch64.ads,

* sem_ch4.adb (Analyze_Aggregate): For Ada2020 delta aggregates, use
the type of the base of the construct to determine the type (or
candidate interpretations) of the delta aggregate. This allows the
construct to appear in a context that expects a private extension.

* sem_aux.adb, sem_aux.ads (Get_Called_Entity): New function to
return the entity associated with the call.
* sem_util.adb, sem_util.ads (Check_Function_Writable_Actuals):
Replace the internal Get_Function_Id with the new
Sem_Aux.Get_Called_Entity.
(Iterate_Call_Parameters): New
procedure to iterate on formals and actuals at the same time.
* sem_ch12.adb (Analyze_Subprogram_Instantiation):
Set SPARK_Mode from spec when set, for analysis
of instance. Restore after analysis of instance.
(Instantiate_Subprogram_Body): Set SPARK_Mode from body when
set, for analysis of body instance. Restored automatically at
the end of the subprogram.
* gnat1drv.adb (Adjust_Global_Switches): Set
Check_Validity_Of_Parameters to False in GNATprove mode.
* opt.ads (Check_Validity_Of_Parameters): Document switch to
set option.
2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
* sem_util.adb (NCT_Tables_In_Use): Move to library level from...
(New_Copy_Tree): ...there. Reset the hash tables only if they
were used in the previous invocation.
* s-htable.adb: Fix typo.
2017-09-08 Bob Duff <duff@adacore.com>
* a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
2017-09-08 Arnaud Charlet <charlet@adacore.com>
* sem_aggr.adb: minor style fix.
2017-09-08 Bob Duff <duff@adacore.com>
* sprint.adb (Write_Corresponding_Source): Ignore if there is
no current source file.
(Write_Name_With_Col_Check, Write_Name_With_Col_Check_Sloc):
Print something helpful in case N is invalid.
* sprint.ads: Minor comment fix.
2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
* exp_aggr.adb: (Aggr_Assignment_OK_For_Backend): Add early return for
access types.
2017-09-08 Bob Duff <duff@adacore.com>
* par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
Ada_2020, along the same lines as the other Ada version pragmas.
2017-09-08 Gary Dismukes <dismukes@adacore.com>
* sem_ch12.adb: Minor typo fixes and reformatting.
2017-09-08 Yannick Moy <moy@adacore.com>
* sem_aggr.adb (Resolve_Record_Aggregate):
Rewrite bounds of aggregate subexpressions which may depend on
discriminants of the enclosing aggregate.
2017-09-08 Yannick Moy <moy@adacore.com>
* sem_ch5.adb: Prevent assertion failure on illegal code.
2017-09-08 Yannick Moy <moy@adacore.com>
* lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
calling Renamed_Entity on an entity which cannot be a renaming.
2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
* exp_aggr.adb: Add with & use clause for Urealp.
(Aggr_Assignment_OK_For_Backend): Accept (almost all)
elementary types instead of just discrete types.
* sem_eval.adb (Expr_Value): Deal with N_Null for access types.
* gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
Be prepared for the FP zero value in the memset case. Add small
guard.
2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
* s-htable.adb (Static_HTable.Reset): Use aggregate instead
of loop.
2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
* exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
of New_Copy because the latter leaves the syntactic structure of
the tree inconsistent (a child is accessible through two parents)
and prevents proper replication of itypes by subsequent calls
to New_Copy_Tree.
* exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
New_Copy because the latter leaves the syntactic structure of the
tree inconsistent (a child is accessible through two parents)
and prevents proper replication of itypes by subsequent calls
to New_Copy_Tree.
* sem_util.adb (In_Subtree): New routine.
(New_Copy_Tree): Reimplemented.
* sem_util.ads (In_Subtree): New routine.
(New_Copy_Tree): Reimplemented.
2017-09-08 Ed Schonberg <schonberg@adacore.com>
* sem_ch13.adb (Resolve_Aspect_Expressions): The expression
for aspect Default_Value is a static scalar value, but it does
not freeze the type. Yhis allows for subsequent representation
clauses for the type.
2017-09-08 Javier Miranda <miranda@adacore.com>
* sem_ch8.adb (Find_Direct_Name.Undefined): Do
not add entries into the undefined reference table when we are
compiling with errors ignored.
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 Vincent Celier <celier@adacore.com>
* gnatcmd.adb: Disregard empty argument of GNAT driver.
2017-09-08 Justin Squirek <squirek@adacore.com>
* checks.adb (Insert_Valid_Check): Manually decorate
the generated temporary for range valdity checks.
2017-09-08 Eric Botcazou <ebotcazou@adacore.com>

2017-09-08 Justin Squirek <squirek@adacore.com>
* switch-c.adb (Scan_Front_End_Switches): Add new warning switch
case to handle underscore flags.
* warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
new procedure to handle underscores.
2017-09-08 Javier Miranda <miranda@adacore.com>
* exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
divisions with fixed point results to avoid generating twice
the runtime check on divide by zero.
* checks.adb (Apply_Divide_Checks): Ensure that operands are
not evaluated twice (once for their runtime checks and once for

New procedure, auxiliary to Expand_Pragma_Check, to handle

to the discriminants of the target object, and these references
are only created when expanding the protected body.

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
the base type of the target entity, because the alternatives
may have distinct subtypes. This is particularly relevant if
the alternatives are aggregates.
2017-09-06 Ed Schonberg <schonberg@adacore.com>
* 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,
and prevents back-end crashes when the aggregate includes a
dynamic "others' association.
2017-09-06 Yannick Moy <moy@adacore.com>
* sem_ch12.adb (Analyze_Instance_And_Renamings):
Set variable to ignore SPARK_Mode in instance before the analysis

2017-09-06 Gary Dismukes <dismukes@adacore.com>
* errout.adb (Error_Msg): Separate the
treatment for warning vs. style messages in inlinings and
instantiations. Prevents blowups on calls to Warn_Insertion for
style messages, which should not be called in that case because
Warning_Msg_Char is not set.
2017-09-06 Justin Squirek <squirek@adacore.com>
* sem_prag.adb (Check_VFA_Conflicts): Created
to group all Volatile_Full_Access checks relating to other

non-limited view.
2017-09-06 Bob Duff <duff@adacore.com>
* sem_ch12.adb (Copy_Generic_Node): When we copy a node
that is a proper body corresponding to a stub, we defer the
adjustment of the sloc until after the correct adjustment has
been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
the adjustment, because it will be outside the range in (the old,
incorrect) S_Adjustment.

(Strip): New routine.
2017-09-06 Bob Duff <duff@adacore.com>
* sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
we include the proper header. Otherwise, we just declare the necessary
things from the capabilities library. This is so we can build on
machines without that library, while still enabling that library.
At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
simply return 0 if the library is not present, or not included
in the link.

uses of 'Image and related attributes as having side effects in
order to avoid replicating such uses.

Hide_Temp_Derefs. The flag defaults to False; CodePeer will
(eventually) override the default.
* pprint.adb (Expression_Image) If the new flag is set, then
suppress the ".all" suffix when displaying a dereference whose
prefix is a use of a value-capturing compiler temp of the sort
generated by Expr_Util.Remove_Side_Effects .

2017-09-06 Ed Schonberg <schonberg@adacore.com>
* exp_ch6.adb (Expand_Call_Helper): Do not optimize calls to

we can use modern Ada in this package.
* s-resfil.ads, s-resfil.adb, a-clrefi.ads, a-clrefi.adb:
Move Ada.Command_Line.Response_File to System.Response_File,
and make Ada.Command_Line.Response_File into a rename of

Ada.Command_Line, which would damage the bootstrap process now
that Ada.Command_Line contains modern Ada (the raise expression).

2017-09-06 Ed Schonberg <schonberg@adacore.com>
* exp_ch5.adb (Make_Field_Assign): If the type
of the right-hand side has stored constraint, use its values
(except for those that are renamings of parent discriminants)
to produce additional assignments for the discriminants of the
left-hand side, which are invisible in the righ-hand side and
not retrievable as selected components.
2017-09-06 Ed Schonberg <schonberg@adacore.com>
* sem_util.adb (Needs_One_Formal): The first formal of such a
function must be a controlling formal, so that Obj.F (X, Y)

aspect specification).
2017-09-06 Eric Botcazou <ebotcazou@adacore.com>

* exp_ch4.adb (Handle_Changed_Representation): For an untagged
derived type with a mixture of renamed and constrained parent
discriminants, the constraint for the target must obtain the
discriminant values from both the operand and from the stored
constraint for it, given that the constrained discriminants are
not visible in the object.
* exp_ch5.adb (Make_Field_Assign): The type of the right-hand
side may be derived from that of the left-hand side (as in the
case of an assignment with a change of representation) so the
discriminant to be used in the retrieval of the value of the
component must be the entity in the type of the right-hand side.

2017-05-02 Ed Schonberg <schonberg@adacore.com>
* exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
Refine predicate for the case where the primitive operation
is a renaming of equality. An overriding operation that is
a user-defined renaming of predefined equality inherits its
slot from the overridden operation. Otherwise it is treated
as a predefined op and occupies the same predefined slot as
equality. A call to it is transformed into a call to its alias,
which is the predefined equality. A dispatching call thus uses
the proper slot if operation is further inherited and called
with class-wide arguments.
2017-05-02 Justin Squirek <squirek@adacore.com>

controlled components that has a trivial Initialize procedure,
insert declaration for finalization counter after object

* checks.ads (Null_Exclusion_Static_Checks): Add Boolean
parameter Array_Comp to indicate the case of an array object
with null-excluding components.
* checks.adb (Null_Exclusion_Static_Checks):
Call Compile_Time_Constraint_Error instead of
Apply_Compile_Time_Constraint_Error in the component case. Also
call that when Array_Comp is True, with an appropriate warning for
the array component case. Only create an explicit initialization
by null in the case of an object of a null-excluding access type
(and no longer do that in the component case).
* sem_ch3.adb (Check_Component): Add a Boolean parameter
Array_Comp defaulted to False. Pass Empty for the Comp
actual when calling Null_Exclusion_Static_Checks in the case
where Comp_Decl matches Object_Decl, because we don't have a
component in that case. In the case of an object or component
of an array type, pass True for Array_Comp on the recursive call
to Check_Component.
2017-05-02 Bob Duff <duff@adacore.com>
* s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
compute the linux priority from the Ada priority. Call this everywhere
required. In particular, the previous version was not doing this
computation when setting the ceiling priority in various places. It
was just converting to C.int, which results in a ceiling that is off
by 1.
2017-05-02 Ed Schonberg <schonberg@adacore.com>

* exp_ch9.adb (Discriminated_Size): Moved to sem_util.
* sem_util.ads, sem_util.adb (Discriminated_Size): Predicate moved
here from exp_ch9, to recognize objects whose creation requires
dynamic allocation, so that the proper warning can be emitted
when restriction No_Implicit_Heap_Allocation is in effect.
* sem_ch3.adb (Analyze_Object_Declaration): Use Discriminated_Size
to emit proper warning when an object that requires dynamic
allocation is declared.
2017-05-02 Tristan Gingold <gingold@adacore.com>

* checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
2017-05-02 Bob Duff <duff@adacore.com>
* exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
to find primitive ops, instead of using an Identifier that will
later be looked up. This is necessary because these ops are not
necessarily visible at all places where we need to call them.
* exp_util.ads: Minor comment fix.
2017-05-02 Ed Schonberg <schonberg@adacore.com>
* sem_ch6.adb (Fully_Conformant_Expressions): Two entity
references are fully conformant if they are both expansions
of the discriminant of a protected type, within one of the
protected operations. One occurrence may be expanded into a
constant declaration while the other is an input parameter to
the corresponding generated subprogram.
2017-05-02 Justin Squirek <squirek@adacore.com>
* sem_ch3.adb (Check_For_Null_Excluding_Components): Created for
recursivly searching composite-types for null-excluding access

array components specially.
2017-05-02 Ed Schonberg <schonberg@adacore.com>
* sem_ch8.adb (Premature_Usage): If the premature usage of
an entity is as the expression in its own object decaration,
rewrite the reference as Any_Id to prevent cascaded errors or
compiler loops when such an entity is used in an address clause.
2017-05-01 Eric Botcazou <ebotcazou@adacore.com>

information if the prefix itself has been rewritten, for ASIS use.
2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
* exp_ch6.adb (Insert_Post_Call_Actions):
Code clean up. Insert the post-call actions after an enclosing
procedure call when N denotes a function call and appears as an
actual parameter in the procedure call.
2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
* freeze.adb (Check_Component_Storage_Order): If there is a clause
for the component, also reject the attribute if the component
doesn't end on a byte boundary and its scalar storage order is
different from that of the enclosing record type.

2017-04-28 Bob Duff <duff@adacore.com>
* sem_util.ads, sem_util.adb (Might_Raise): New function
that replaces Is_Exception_Safe, but has the opposite
sense. Is_Exception_Safe was missing various cases -- calls inside
a pragma Debug, calls inside an 'if' or assignment statement,
etc. Might_Raise now walks the entire subtree looking for things
that can raise.
* exp_ch9.adb (Is_Exception_Safe): Remove.
(Build_Protected_Subprogram_Body): Replace call to
Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
constants where possible).
* exp_ch7.adb: Rename Is_Protected_Body -->
Is_Protected_Subp_Body. A protected_body is something different
in the grammar.

* sem_ch13.adb (Analyze_Aspect_Specifications, case
Interrupt_Handler and Attach_Handler): Generate reference
to protected operation to prevent spurious warnings about
unreferenced entities. Previous scheme failed with style checks
enabled.
2017-04-28 Ed Schonberg <schonberg@adacore.com>
* sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
that follows an expression function must not be relocated to
the generated body, because it applies to the code that follows.
2017-04-28 Gary Dismukes <dismukes@adacore.com>
* sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
Relaxed_RM_Semantics to avoid having CodePeer issue errors on

2017-04-28 Ed Schonberg <schonberg@adacore.com>
* sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
node between access types, freeze the designated type as well,
so that dispatch table pointers are created in the proper scope,
and not in the constructed body of the expression function.
2017-04-28 Bob Duff <duff@adacore.com>
* alloc.ads (Nodes_Initial): Go back to previous value. The large
value makes large compilations faster, but small compilations slower.

* warnsw.ads: Minor fix for incorrect wording in comment.
2017-04-28 Ed Schonberg <schonberg@adacore.com>
* sem_res.adb (In_Instance_Code): New predicate in
Valid_Conversion, to determine whether a type conversion appears
as (or within) an actual for a formal object. Type conversions
in instances are not rechecked in Valid_Conversion because
visibility changes between generic location andi instance may
lead to spurious errors, but conversions within an actual must be
fully checked, and they are not fully resolved when pre-analyzing
the actuals.
2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
* exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
New_Copy_Tree instead of Relocate_Node as any subsequent copies
of the relocated node will have mangled Parent pointers.

* g-comlin.adb (Sort_Sections): remove useless test.
2017-04-27 Claire Dross <dross@adacore.com>
* a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
allow the use of regular equality over elements in contracts.
(Formal_Model): Ghost package containing model functions that are

* gnat1drv.adb: Code cleanup.
2017-04-27 Ed Schonberg <schonberg@adacore.com>
* exp_util.adb (Replace_Entity): The prefix of a 'Result
attribute reference in a post- condition is the subprogram to
which the condition applies. If the condition is inherited
by a type extension, the prefix becomes a reference to the
inherited operation, but there is no need to create a wrapper
for this operation, because 'Result is expanded independently
when elaborating the postconditions.
2017-04-27 Bob Duff <duff@adacore.com>
* sinput.adb: Minor code cleanup.
* namet.adb (Append): Create faster versions of
Append(String) and Append(Name_Id) by using slice assignment

unnecessary tests; Is_Generic_Instance is defined for all
entities.
* sem_util.ads, sem_util.adb (In_Parameter_Specification):
Remove unused function.
* alloc.ads (Nodes_Initial): Use a much larger value, because
the compiler was spending a lot of time copying the nodes table
when it grows. This number was chosen in 1996, so is rather out
of date with current memory sizes. Anyway, it's virtual memory.
Get rid of Orig_Nodes_...; use Node_... instead.
* atree.adb (Lock): Do not release the Nodes tables; it's a
waste of time.
Orig_Nodes_ ==> Nodes_
* nlists.adb: Orig_Nodes_ ==> Nodes_
* g-table.adb: Remove unused "with" clause.
* g-table.ads, table.ads: Remove Big_Table_Type, which should

to manage the secondary stack when an enclosing scope already
performs this functionality (aka relaxed management). Switch
-gnatd.s may be used to force strict management in which case
the block will manage the secondary stack unconditionally. Add
a guard to stop the traversal when encountering a package or a
subprogram scope.
2017-04-27 Ed Schonberg <schonberg@adacore.com>
* sem_res.adb (Resolve_Call): Refine further the handling of
limited views of return types in function calls. If the function
that returns a limited view appears in the current unit,
we do not replace its type by the non-limited view because
this transformation is performed int the back-end. However,
the type of the call itself must be the non-limited view, to
prevent spurious resolution errors.
2017-04-27 Ed Schonberg <schonberg@adacore.com>
* einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
Removed, proposed implementation using generics for class-wide
preconditions proved impractical.
(Class_Wide_Clone): New attribute of subprogram. Designates
subprogram created for primitive operations with class-wide
pre/postconditions that contain calls to other primitives. The
clone holds the body of the original primitive, but the
pre/postonditions do not apply to it. The original body is
rewritten as a wrapper for a call to the clone.
(Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
the flag is set, no code for the corresponding pre/postconditions
is inserted into its body.

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.
Move Set_Source_File_Index_Table into the private part, because
it is used only in the body and in children. Use trickery to
modify the dope in the generic instantiation case. It's ugly,
but not as ugly as the previous method. Fix documentation.

remove return condition on interfaces, always use the
private type for interfaces, and move the processing of types

* 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.

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.

2017-04-25 Bob Duff <duff@adacore.com>
* sem_ch8.adb (Use_One_Type): If a use_type_clause
is redundant, set its Used_Operations to empty. This is only
necessary for use clauses that appear in the parent of a generic

carried over from the original context (where it was probably
not redundant).

Set_Warnings_Mode_Off): Use the correct source file for

* sem_ch4.adb (Analyze_Selected_Component): Refine analysis
of prefix whose type is a current instance of a synchronized
type. If the prefix is an object this is an external call (or
requeue) that can only access public operations of the object. The

* uname.ads, uname.adb (Is_Predefined_Unit_Name,
Is_Internal_Unit_Name): New functions for operating on unit
names, as opposed to file names. There's some duplicated code
with fname.adb, which is unfortunate, but it seems like we don't
want to add dependencies here.
* 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
Is_Predefined_File_Name and Is_Internal_File_Name can be called
for ALI files, and fix the code so it works properly for ALI
files. E.g. these should return True for "system.ali".
2017-04-25 Justin Squirek <squirek@adacore.com>

variable usage. We shouldn't be communicating information via
the global name buffer.
* bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
