recognize use of Iterator_Specification in an element iterator.
To simplify disambiguation between the two iterator forms, mark
the component association as carrying an Iterator_Specification
only when the element iterator (using "OF") is used.
* par-ch5.adb (P_Loop_Parameter_Specification): In Ada_2020,
parse iterator filter when present.
(P_Iterator_Specification): Ditto. Remove declaration of
P_Iterator_Specification, now in parent unit.
* exp_ch5.adb (Expand_N_Loop_Statement): Apply Iterator filter
when present.
(Expand_Iterator_Loop_Over_Array): Ditto.
(Expand_Iterator_Loop_Over_Container): Ditto.
* sem_aggr.adb (Resolve_Array_Aggregate): Emit error nessage if
an iterated component association includes a iterator
specificcation with an element iterator, i.e. one that uses the
OF keyword.
* sem_ch5.adb (Analyze_Iterator_Specification): Analyze Iterator
filter when present.
(Analyze_Loop_Parameter_Specification): Ditto.
* sinfo.adb: Suprogram bodies for new syntactic element
Iterator_Filter.
* sinfo.ads: Add Iterator_Filter to relevant nodes. Structure
of Component_Association and Iteroted_Component_Association
nodes is modified to take into account the possible presence of
an iterator specification in the latter.
2020-07-08 Yannick Moy <moy@adacore.com>
* sem_util.ads, sem_util.adb (Is_Attribute_Loop_Entry): New

else" operators.
2020-07-08 Gary Dismukes <dismukes@adacore.com>
* exp_ch6.adb (Expand_Simple_Function_Return): Remove ugly code
that was copying the return expression, resetting Analyzed
flags, etc. for the return expression of static expression
functions.
* inline.adb (Inline_Static_Expression_Function_Call): Set the
Parent of the copied expression to that of the call. This avoids
a blowup in Insert_Actions when GNATprove_Mode is set and there
are nested SEF calls. Add ??? comment.
* sem_ch6.adb (Analyze_Expression_Function): In the case of a
static expression function, create a new copy of the expression
and replace the function's expression with the copy; the
original expression is used in the expression function's body
and will be analyzed and rewritten, and we need to save a clean
copy for later use in processing static calls to the function.
This allows removing the kludgy code that was in
Expand_Simple_Function_Return.
* sem_eval.adb (Eval_Qualified_Expression): Return immediately
if any errors have been posted on the qualified expression, to
avoid blowups when GNATprove_Mode is enabled (or with -gnatd.F),
since illegal static expressions are handled differently in that
case and attempting to fold such expressions would fail.
2020-07-08 Eric Botcazou <ebotcazou@adacore.com>

(List_Record_Layout): Likewise.
(List_Structural_Record_Layout): Use First_Discriminant instead

back to spec.
2020-07-07 Ed Schonberg <schonberg@adacore.com>
* exp_ch3.adb (Build_Access_Subprogram_Wrapper_Body): Create
proper subprogram specification for body, using names in the
subprogram declaration but distinct entities.
* exp_ch6.adb (Expand_Call): If this is an indirect call
involving a subprogram wrapper, insert pointer parameter in list
of actuals with a parameter association, not as a positional
parameter.
2020-07-07 Justin Squirek <squirek@adacore.com>
* exp_ch6.adb (Expand_Branch): Verify the original node is a
conditional expression before recursing further.
(Insert_Level_Assign): Transform assertion into an explicit
raise.

(Resolve_Indexed_Component): Remove useless conditional construct.
2020-07-07 Piotr Trojanek <trojanek@adacore.com>
* contracts.adb (Analyze_Entry_Or_Subprogram_Contract,

condition for doing invariant checks so that in-mode parameters
of procedures are also checked (required by AI05-0289, and
restricted to procedures by AI12-0044). This is done in a
procedure's nested postconditions procedure.
* exp_ch6.adb (Expand_Actuals): Also perform postcall invariant
checks for in parameters of procedures (but not functions).
Moved invariant-checking code to end of Expand_Actuals
(including the nested function Is_Public_Subp).

them alphabetically ordered.
2020-07-07 Piotr Trojanek <trojanek@adacore.com>

* libgnat/g-catiio.ads: Document newly supported format. Add
ISO_Time constant, for convenience.
* libgnat/g-catiio.adb (Image_Helper): New helper function to do
all the formatting work, called by the two exported Image
functions. Add support for "%:::z" here. Add a Time_Zone
parameter used by the "%:::z" processing. This parameter is not
used for the actual time zone computations; local time is always
used for that, for ease of implementation reasons. It would
make sense to use Append throughout this function, but that's a
cleanup for another day.
(Image): Modify these to pass the local time zone, or the
specified time zone, as appropriate.
2020-07-06 Bob Duff <duff@adacore.com>
* libgnat/g-catiio.ads: Change the regular expression that
documents the allowed format to match what ISO-8601 allows.
* libgnat/g-catiio.adb (Scan_Subsecond): Rewrite so it doesn't
assume the subsecond comes last.
(Parse_ISO_8601): Parse an optional subsecond, followed by an
optional time zone, rather than making these alternatives to
each other.
2020-07-06 Bob Duff <duff@adacore.com>
* libgnat/g-catiio.adb (Parse_ISO_8601): Minor cleanups:
Give some objects clearer names.
Make some objects more local to where they are used.
Remove some validity checks that can't fail, because some of
the variables tested have been moved so they're not visible here.
Anyway, Wrong_Syntax is about errors in the input, not data
validity.
Use Time_Zone_Seen instead of Local_Sign = ' ' to determine
that a time zone indication was seen.
We don't need to distinguish two different kinds of
syntax error (End_Of_Source_Reached and Wrong_Syntax),
so use Wrong_Syntax always.
Remove comment, "Certain scanning scenarios may handle
this exception on their own."; there are no such scenarios.
2020-07-06 Bob Duff <duff@adacore.com>
* libgnat/g-catiio.ads, libgnat/g-catiio.adb (Image): New
function. It might seem like the local-time Image should be
implemented in terms of the Time_Zone Image, but that would be
far harder to implement, so we do it the other way around.
2020-07-06 Thomas Quinot <quinot@adacore.com>
* libgnat/g-sechas.ads, libgnat/g-sechas.adb: Refactor to use
Stream_Element_Array as the internal buffer type.

(Is_Potentially_Unevaluated): Adding support to detect
potentially unevaluated components of array aggregates.
2020-07-06 Bob Duff <duff@adacore.com>
* libgnat/g-catiio.adb (Parse_ISO_8601): New name for
Parse_ISO_8861_UTC. 8601 is the correct ISO standard number.
Also, "UTC" was confusing. All Time values are represented in
UTC, but the ISO 8601 date strings include a time zone.
If a time zone was specified, call
Ada.Calendar.Formatting.Time_Of instead of
GNAT.Calendar.Time_Of, because the latter adjusts to the current
time zone, whereas we want to use (just) the time zone specified
in the ISO string. This allows us to pass Time_Zone instead to
Time_Of, instead of adjusting by Local_Disp by hand.
If no time zone was specified, call GNAT.Calendar.Time_Of as
before.
Use expanded names to clarify which Time_Of is being called.
Remove redundant comment, and move nonredundant part of the
commment to the spec.
(Value): Minor: use "not in" instead of "or else".
* libgnat/g-catiio.ads: Comment moved here. Correct the ISO
standard number.
* libgnat/g-calend.adb: Add ??? comments.
* libgnat/a-calend.ads, libgnat/a-calend.adb: Update obsolete
comments regarding the representation of type Time. Move the
information about the epoch (year 2150) to the spec, and avoid
uttering "2150" more than once.
* libgnat/a-catizo.ads (Time_Offset): Add comment.
2020-07-06 Ed Schonberg <schonberg@adacore.com>
* exp_ch5.adb (Find_Component): If the target type is a derived
record type and the required component is a discriminant that is
renamed in the derived type declaration, use the name of the
original discriminant to locate the intended target component.
2020-07-06 Justin Squirek <squirek@adacore.com>

a warning if the attribute prefix is a current instance
reference within an aspect of a type or subtype.
(Address_Checks): Replace test of Is_Object (Ent) with
Is_Object_Reference (P) so that testing for current instances
will be done.
(Eval_Attribute): Add test for current instance reference, to
ensure that we still fold array attributes when current
instances are involved, since value prefixes are allowed for
array attributes, and will now be excluded by
Is_Object_Reference.
* sem_util.ads (Is_Current_Instance_Reference_In_Type_Aspect):
New exported query function.
* sem_util.adb (Is_Object_Reference): Return False for the case
where N is a current instance reference within an
aspect_specification of a type or subtype (basically if the
reference occurs within a predicate, invariant, or DIC aspect
expression).
(Is_Current_Instance_Reference_In_Type_Aspect): New function
that tests whether a node is a reference to a current instance
formal of a predicate, invariant, or
Default_Initial_Condition (DIC) subprogram.
2020-07-06 Ed Schonberg <schonberg@adacore.com>
* sem_res.adb (Resolve_Declare_Expression): New subprogram, to

subprogram declaration.
(Build_Access_Subprogram_Wrapper): Examine aspect specifications
of an Access_To_Subprogram declaration. If pre- or
postconditions are declared for it, create declaration for
subprogram wrapper and add the corresponding aspect
specifications to it. Replace occurrences of the type name by
that of the generated subprogram, so that attributes 'Old and

* aspects.ads (type Aspect_Id): Add Aspect_Static as a Boolean
aspect, and update the Is_Representation_Aspect, Aspect_Names,
and Aspect_Delay arrays.
* exp_ch6.adb (Expand_Simple_Function_Return): In the case of a
return for a static expression function, capture a copy of the
expression of the return statement before it's expanded and
reset its Analyzed flags. Then, just before leaving this
procedure, if the expression was rewritten, set the
Original_Node of the rewritten expression to the new copy and
also set the Expression of the associated static expression
function to designate that copy. This ensures that later copies
of the expression made via New_Copy_Tree will fully copy all
nodes of the expression tree.
* inline.ads (Inline_Static_Expression_Function_Call): New
procedure to evaluate and produce the result of a static call to
a static expression function.
* inline.adb: Add with and use for Sem_Res.
(Establish_Actual_Mapping_For_Inlined_Call): New procedure
extracted from code in Expand_Inlined_Call that traverses the
actuals and formals of an inlined call and in some cases creates
temporaries for holding the actuals, plus establishes an
association between formals and actuals (via the Renamed_Object
fields of the formals).
(Formal_Is_Used_Once): Function removed from Expand_Inlined_Call
and now nested in the above procedure.
(Expand_Inlined_Call): Code for doing the formal/actual
traversal is moved to Create_Actual_Temporaries and replaced
with a call to that new procedure.
(Inline_Static_Expression_Function_Call): New procedure to
evaluate a static call to a static expression function,
substituting actuals for their corresponding formals and
producing a fully folded and static result expression. The
function has subsidiary functions Replace_Formal and Reset_Sloc
that take care of doing the mapping of formals to actuals and
resetting the Slocs of subnodes of the mapped expression to that
of the call so errors will be flagged on the call rather than
function.
* sem_ch6.adb (Analyze_Expression_Function): In the case of a
static expression function, perform an additional preanalysis of
the function's expression to ensure that it's a potentially
static expression (according to the requirements of
6.8(3.2/5-3.4/5)), and issue an error if it's not. The global
flag Checking_Potentially_Static_Expression is set and unset
around this checking.
* sem_ch13.adb (Analyze_Aspect_Static): New procedure to enforce
selected requirements of the new aspect Static on expression
functions, including checking that the language version is
Ada_2020 and that the entity to which it applies is an
expression function whose formal parameters are of a static
subtype and have mode 'in', its result subtype is a static
subtype, and it has no pre- or postcondition aspects. A ???
comment is added to indicate the need for adding checking that
type invariants don't apply to the result type if the function
is a boundary entity.
(Analyze_One_Aspect): Call Analyze_Aspect_Static for aspect
Static.
* sem_elab.adb (Build_Call_Marker): Return without creating a
call marker when the subprogram is a static expression function,
since no ABE checking is needed for such functions.
* sem_eval.ads (Checking_Potentially_Static_Expression): New
function to return whether the checking for potentially static
expressions is enabled.
(Set_Checking_Potentially_Static_Expression): New procedure to
enable or disable checking of potentially static expressions.
* sem_eval.adb (Checking_For_Potentially_Static_Expression): New
global flag for determining whether preanalysis of potentially
static expression is being done, which affects the behavior of
certain static evaluation routines.
(Checking_Potentially_Static_Expression): New function to return
whether the checking for potentially static expressions is
enabled.
(Eval_Call): When evaluating a call within a static expression
function with checking of potentially static expression
functions enabled, substitutes a static value in place of the
call to allow folding of the expression.
(Eval_Entity_Name): When evaluating a formal parameter of a
static expression function with checking of potentially static
expression functions enabled, substitutes a static value in
place of the reference to the formal to allow folding of the
expression.
(Set_Checking_Potentially_Static_Expression): New procedure to
enable or disable checking of potentially static expressions.
* sem_res.adb (Resolve_Call): Test for a recursive call
occurring within a static expression function and issue an error
for such a call. Prevent the establishment of a transient scope
in the case this is a call to a (string-returning) static
expression function. When calling a static expression function,
if no error has been posted on the function, call
Inline_Static_Expression_Function_Call to convert the call into
its equivalent static value.
* sem_util.ads (Is_Static_Expression_Function): New function
returning whether the subprogram entity passed to it is a static
expression function.
(Is_Static_Expression_Function_Call): New function to determine
whether the call node passed to it is a static call to a static
expression function.
* sem_util.adb (Compile_Time_Constraint_Error): Suppress
compile-time Constraint_Error reporting when checking for a
potentially static expression.
(Is_Static_Expression_Function): New function returning whether
the subprogram entity passed to it is a static expression
function by testing for the presence of aspect Static.
(Has_All_Static_Actuals): New function in
Is_Static_Expression_Function_Call that traverses the actual
parameters of a function call and returns True only when all of
the actuals are given by static expressions. In the case of a
string-returning function, we call Resolve on each actual to
ensure that their Is_Static_Expression flag properly reflects
whether they're static, to allow suppressing creation of a
transient scope within Resolve_Call. A prominent ??? comment is
added to explain this rather unconventional call to Resolve.
(Is_Static_Expression_Function_Call): New function that
determines whether a node passed to it is a call to a static
expression function all of whose actual parameters are given by
static expressions.

* exp_ch4.adb (Optimize_Length_Comparison): New local variable to

* sem.adb (Do_Analyze): Save/restore In_Declare_Expr.
* sem_ch4.adb (Analyze_Expression_With_Actions): Give this node
its own scope. That seems better in general, but it is
necessary for declare_expressions. For example, an identifier
declared in a declare_expression should not clash with the same
identifier in an outer scope. If this is a declare_expression,
indicated by Comes_From_Source, then check legality rules, and
incr/decr In_Declare_Expr.

Validate_Literal_Aspect. This is where most of the legality
checking occurs for an aspect specification for one of the three
new aspects, as well as resolution of the subprogram named in
the aspect specification. Follow example of other aspects (e.g.,
Validate_Literal_Aspect is called in much the same way as
Validate_Iterable_Aspect in Analyze_Aspects_At_Freeze_Point; a
small amount of legality checking is performed in
Analyze_One_Aspect in much the same way as for Default_Value or
Default_Component_Value aspects). Most of the work is done in
Validate_Literal_Aspect.
* contracts.adb (Add_Contract_Item): Call
Validate_Literal_Aspect in much the same way that
Validate_Iterable_Aspect was already being called.
* sem_res.adb (Resolve): Rewrite a literal as a call if it is a

* sem_ch6.adb (Fully_Conformant_Expressions): Two numeric
literals that have different text but the same value (e.g.,
12345 and 12_345) do not conform if they are user-defined
literals. Introduce a new function
User_Defined_Numeric_Literal_Mismatch to avoid duplication in
making this check.
* sem_type.adb (Has_Compatible_Type): A numeric literal can be
compatible with a non-numeric type (and a string literal can be
compatible with a non-string type) if it can be interpreted as a
user-defined literal.

type designating a specific tagged type, but not if the expression
was null or tag checks are suppressed for the type, and use Not In
operator rather than comparing the tags explicitly.
* sem.adb (Analyze): Handle all Suppress values.

Target to silence potential warnings.
(Expand_N_If_Expression): Add calculation to check when the if
expression is used directly in the context of an actual of an
anonymous access type and add a special path to force expansion
of the if expression in this case.
* exp_ch6.adb (Expand_Branch): Generate an assignment to the
level temporary for a given branch.
(Expand_Call_Helper): Add expansion to allow for creating a
temporary to store associated accessiblity levels on each branch
of the conditional expression. Also perform expansion of
function calls into expressions with actions, and fixup
references to N with Call_Node.
(Insert_Level_Assign): Move through nested conditional
expressions to each branch.
* sem_util.ads, sem_util.adb (Is_Anonymous_Access_Actual): Added
to detect when to force expansion of if expressions.

especially since they don't make the code any easier to read.
2020-06-15 Piotr Trojanek <trojanek@adacore.com>
* aspects.ads (Aspect_Id): Add Aspect_Relaxed_Initialization.
(Implementation_Defined_Aspect): Add new aspect.

* exp_put_image.adb, libgnat/s-putima.adb, libgnat/s-putima.ads,
rtsfind.ads: Enable Put_Image if Is_Access_Subprogram_Type (Typ).
Remove comment saying it's disabled in that case. Rename
Put_Image_Access_Prot to be Put_Image_Access_Prot_Subp to
clarify that we're talking about access-to-subprogram, not
access-to-protected-object.
2020-06-15 Bob Duff <duff@adacore.com>
* sem_attr.adb (Check_Image_Type): New procedure for checking
the type, depending on language version. Disable the Ada 2020
support until the corresponding expander work is done.
(Analyze_Image_Attribute): Call Check_Image_Type. Rearrange the
code to be simplier and more logical. When P_Type is modified,
modify P_Base_Type accordingly.
* sem_util.adb (Is_Object_Image): Do not return False if the
prefix is a type. X'Image should be considered an image of an
object iff X is an object (albeit illegal pre-2020 if
nonscalar).
2020-06-15 Bob Duff <duff@adacore.com>
* libgnat/s-putima.ads, libgnat/s-putima.adb
(Put_Image_Access_Subp, Put_Image_Access_Prot): New procedures
for printing access-to-subprogram objects. Remove an explicit
" ", because Put_Image includes the annoying leading blank.
* rtsfind.ads: Add new procedures in s-putima.
* exp_put_image.adb: Call new procedures as appropriate.
2020-06-15 Bob Duff <duff@adacore.com>
* exp_imgv.adb (Expand_Image_Attribute): Allow private types.
Put_Image generates Image for numeric types, and private types
whose full type is numeric. This requires the Conversion_OK flag
for integer and floating-point types. For fixed point, we need
the extra conversion.
* exp_put_image.adb (Build_Elementary_Put_Image_Call): Remove
special handling of real types.
(Enable_Put_Image): Enable for reals.
2020-06-15 Bob Duff <duff@adacore.com>
* exp_attr.adb (Put_Image): Use underlying type for strings.
Remove unchecked union processing.
* exp_put_image.adb (Tagged_Put_Image_Enabled): Use -gnatd_z to
enable default Put_Image for tagged types. This allows testing
that feature.
(Build_String_Put_Image_Call): Set Conversion_OK flag.
(Make_Component_List_Attributes): Remove unchecked union
processing.
(Enable_Put_Image): Disable for unchecked unions. Enable for
nonscalar types (which were mistakenly disabled in earlier
changes).
* debug.adb: Document -gnatd_z switch.
* libgnat/s-putima.adb (Put_Image_String, Put_Image_Wide_String,
Put_Image_Wide_Wide_String): Double double-quote characters.
Forget about special handling of control characters for now --
that's rare enough to not be a priority, and it's not clear what
the right thing to do is anyway.
* namet.adb: Minor: Improve debugger-friendliness.
* sinfo.ads: Minor: Add "???" comment.
2020-06-15 Piotr Trojanek <trojanek@adacore.com>
* sem_util.ads, sem_util.adb (Is_Renaming_Declaration): Remove.
2020-06-15 Ed Schonberg <schonberg@adacore.com>
* freeze.adb (Freeze_Expression): When traversing the tree
looking for the proper insertion point for the freeze node of an
entity that is declared in an outer scope, set the candidate
subprogram body node properly. Previous code has an off-by-one
error.
2020-06-15 Eric Botcazou <ebotcazou@adacore.com>
* exp_attr.adb (Expand_N_Attribute_Reference) <Has_Same_Storage>:
Do not do superfluous work. Add the condition (X'Size /= 0) on
both paths and turn binary AND into short-circuit AND THEN.
2020-06-15 Steve Baird <baird@adacore.com>
* sem_attr.adb (Analyze_Attribute): In the Loop_Entry case,
replace a call to Statically_Denotes_Object with a call to
Statically_Names_Object and clean up the preceding comment.
2020-06-15 Eric Botcazou <ebotcazou@adacore.com>
* sem_res.adb (Resolve_Set_Membership): Remove local variable.
In the non-overloaded case, call Intersect_Types on the left
operand and the first alternative to get the resolution type.
But test the subtype of the left operand to give the warning.
2020-06-12 Steve Baird <baird@adacore.com>
* sem_res.adb (Valid_Conversion): The simpler cases of
violations of the aforementioned 8.6 rule are already handled
correctly. These include cases where the operand of the type
conversion is an access parameter or a stand-alone object of an
anonymous access type. Add code to detect violations where the
operand of the type conversion is an access discriminant whose
accessibility level is tied to one of the other simpler cases.
This is implemented in a new function,
Valid_Conversion.Is_Discrim_Of_Bad_Access_Conversion_Argument,
which is called in place of the previous test.
2020-06-12 Bob Duff <duff@adacore.com>
* exp_attr.adb (Put_Image): Remove assertion. This assertion is
False in mixed-Ada-version programs.
* exp_put_image.adb (Tagged_Put_Image_Enabled): New flag to make
it easy to experiment with Put_Image on tagged types. False in
this version.
(Enable_Put_Image): Enable in pre-2020. Workarounds: Disable
for tagged types if Tagged_Put_Image_Enabled is False. Disable
for access-to-subprogram types. Disable if errors have been
detected, or Sink is unavailable.
(Preload_Sink): Move all conditionals here, from Sem_Ch10, so
they can be nearby related code in Enable_Put_Image. Load Sink
only if we have seen a tagged type. This removes the dilemma
about calling Preload_Sink when compiling the compiler, which
caused unwanted dependences.
* exp_put_image.ads (Preload_Sink): New formal Compilation_Unit,
needed to move all conditionals here, from Sem_Ch10.
* libgnat/a-stouut.adb (Put_UTF_8): Make this suitable for
inlining, so we don't get warnings about inlining in some tests.
And so it can be inlined!
* opt.ads (Tagged_Seen): New flag (see Preload_Sink).
* scng.adb (Scan): Set new Tagged_Seen flag.
* sem_ch10.adb (Analyze_Compilation_Unit): Move conditionals and
comments regarding Preload_Sink into Preload_Sink.
2020-06-12 Arnaud Charlet <charlet@adacore.com>

containing array attributes wrt Ada 83 detection.
2020-06-12 Steve Baird <baird@adacore.com>
* sem_util.ads, sem_util.adb: Define 3 new Boolean-valued
functions - Statically_Denotes_Entity,
Statically_Denotes_Object, and Statically_Names_Object. The
first two were taken from sem_attr.adb. The term "statically
names" is defined in the Ada RM and the new function
Statically_Names_Object is intended to reflect that definition,
or more precisely, as described in a comment in the code, to
reflect the expected future definition of that term.
* sem_attr.adb: Delete functions Statically_Denotes_Object and
Statically_Denotes_Entity; these two functions have been moved
to package Sem_Util. Replace call to Statically_Denotes_Object
with a call to Statically_Names_Object as per AI12-0217 (a
binding interpretation, so no Ada_Version check).
* exp_ch9.adb (Expand_Entry_Barrier.Is_Simple_Barrier): Change
name of function (it was previously Is_Simple_Barrier_Name)
because the function should return True in the case of a static
expression; implement this requirement. Change function to
include a call to Statically_Names_Object so that, for Ada_2020
and later, it will return True for appropriate subcomponent
names.
(Expand_Entry_Barrier.Is_Pure_Barrier): Handle
N_Indexed_Component and N_Selected_Component cases by calling
Statically_Names_Object.
(Expand_Entry_Barrier): Reorganize to treat Simple_Barriers and
Pure_Barriers more uniformly. Prevent cascaded errors.
2020-06-12 Ed Schonberg <schonberg@adacore.com>
* sem_ch12.adb (Find_Matching_Actual): Add guard on search loops
to detect a compilation error when using a compiler built
without assertions.
(Instantiate_Formal_Subprogram): Create a new subprogram name
for the actual only if formal has contract aspects and expansion
is enabled.
2020-06-12 Eric Botcazou <ebotcazou@adacore.com>
* exp_aggr.adb: Add with and use clauses for Sem_Mech.
(Get_Base_Object): New function to get the base object of a node.
(In_Place_Assign_OK): Add Target_Object parameter. Deal with a
qualified expression on entry. Remove short-circuit for array
aggregates with a single "others" choice. Do not look into the
components of the aggregate if the parent is an allocator.
(Check_Component): Add T_OK parameter and rewrite.
(Safe_Component): Invoke Check_Component with T_OK set to False.
(Convert_To_Assignments): Try to use an in-place assignment for
any target; for that, call Get_Base_Object on the target and pass
the result to In_Place_Assign_OK.
(Expand_Array_Aggregate): Use Parent_Kind and Parent_Node more
consistently. For an assignment, call Get_Base_Object on the
target and pass the result to In_Place_Assign_OK.
2020-06-12 Dmitriy Anisimkov <anisimko@adacore.com>
* socket.c (__gnat_minus_500ms): Use GetVersionEx to detect
Windows Server version.
* libgnat/g-sothco.ads (Minus_500ms_Windows_Timeout): Remade to
Boolean constant.
* libgnat/g-socket.adb (Set_Socket_Option): Use
Minus_500ms_Windows_Timeout constant instead of function call.
2020-06-12 Arnaud Charlet <charlet@adacore.com>
* libgnat/a-coinho.ads, libgnat/a-coinho.adb,
libgnat/a-coinho__shared.ads, libgnat/a-coinho__shared.adb
(Swap): New procedure.
2020-06-12 Arnaud Charlet <charlet@adacore.com>

(Build_Private_Protected_Declaration): Moved to sem_ch6.adb.
(Expand_N_Protected_Body): Do nothing for a subprogram declared
in a protected body.
* sem_ch6.adb (Build_Internal_Protected_Declaration): Moved from
exp_ch9.adb and renamed and fixed to ensure in particular that
such subprograms have convention Intrinsic and have no protected
version.
(Analyze_Subprogram_Body_Helper): Call
Build_Internal_Protected_Declaration.
(Move_Pragmas): Moved up and merged with the more general
version from Build_Private_Protected_Declaration. We only want
to copy selected pragmas, most pragmas are not suitable for a
copy on the spec.
2020-06-12 Ed Schonberg <schonberg@adacore.com>
* sem_ch6.adb (Check_Overriding_Indicatior): Reject an
overriding indicator on a subprogram declared within a protected

* exp_put_image.ads, exp_put_image.adb (Preload_Sink): Procedure
for preloading type Sink. This has the side effect of loading
various dependents, including Ada.Strings.UTF_Encoding.
(Enable_Put_Image): Disable Put_Image in pre-2020 versions of
Ada. This limitation can probably be lifted later. Enable for
tagged types except in predefined units. Disable for CPP types;
Put_Image is legal, just prints the type name.
* sem_attr.adb (Check_Put_Image_Attribute): Don't complain about
Put_Image of CPP types; instead call the "unknown" version of
Put_Image.

new name to be used in call inside wrapper body. This names
carries the interpretations of the actual, and is resolved when
the body is analyzed.

specification. Add pragmas Ada_2020.
* libgnat/a-stouut.ads, libgnat/a-stteou.ads: Add Preelaborate,
because the Big_Numbers packages have Preelaborate, and now
depend on these Text_Output packages.
2020-06-12 Eric Botcazou <ebotcazou@adacore.com>
* einfo.ads (No_Return): Document it for all subprograms.

references to SPARK RM 7.1.3 rule numbers.
2020-06-11 Ed Schonberg <schonberg@adacore.com>
* sem_warn.adb (Warn_On_Overlapping_Actuals): Simplify code,
remove inner predicate Is_Covered_Formal, preserve warning for
two overlapping composite types when only one is writable, and
for two overlapping and writable elementary types.
2020-06-11 Steve Baird <baird@adacore.com>
* contracts.adb (Add_Contract_Item): Support specifying

which performs the work that needs to be done for both object
declarations and types.
(Analyze_Object_Contract): Add a call to
Check_Type_Or_Object_External_Properties and remove the code in
this procedure which did much of the work that is now performed
by that call.
(Analyze_Type_Contract): Implement this new routine as nothing
more than a call to Check_Type_Or_Object_External_Properties.
* contracts.ads: Update comment for Add_Contract_To_Item because
types can have contracts. Follow (questionable) precedent and
declare new routine Analyze_Type_Contract as visible (following
example of Analyze_Object_Contract), despite the fact that it is
never called from outside of the package where it is declared.
* einfo.adb (Contract, Set_Contract): Id argument can be a type;
support this case.
(Write_Field34_Name): Field name is "contract" for a type.
* einfo.ads: Update comment describing Contract attribute.
* sem_ch3.adb (Build_Derived_Numeric_Type): Is_Volatile should
return same answer for all subtypes of a given type. Thus, when
building the base type for something like type Volatile_1_To_10
is range 1 .. 10 with Volatile; that basetype should be marked
as being volatile.
(Access_Type_Declaration): Add SPARK-specific legality check
that the designated type of an access type shall be compatible
with respect to volatility with the access type.
* sem_ch12.adb (Check_Shared_Variable_Control_Aspects): Add
SPARK-specific legality check that an actual type parameter in
an instantiation shall be compatible with respect to volatility
with the corresponding formal type.

for aspect specs for the 4 volatility refinement aspects that
were already being performed for all language-defined aspects.

Effective_Reads, Effective_Writes): Initial implementation of
new functions for querying aspect values.
(Check_Volatility_Compatibility): New procedure intended for use
in checking all SPARK legality rules of the form "<> shall be
compatible with respect to volatility with <>".
(Has_Enabled_Property): Update comment because Item_Id can be a
type. Change name of nested Variable_Has_Enabled_Property
function to Type_Or_Variable_Has_Enabled_Property; add a
parameter to that function because recursion may be needed,
e.g., in the case of a derived typ). Cope with the case where
the argument to Has_Enabled_Property is a type.
2020-06-11 Piotr Trojanek <trojanek@adacore.com>
* sem_aggr.adb (Add_Association): Add assertion about the formal
parameters.
(Propagate_Discriminants): Always add an explicit component
association, so that an "others => <>" association is never
needed.

* exp_put_image.adb (Build_Elementary_Put_Image_Call): If the
underlying type is real, call Put_Image_Unknown.

Put_Image_Unknown.
* libgnat/s-putima.ads, libgnat/s-putima.adb
(Put_Image_Unknown): Add Type_Name parameter. Remove
overly-detailed documentation of what it does; better to leave
it open.

* sem_aggr.adb (Build_Constrained_Itype): Move to Sem_Util.
* sem_ch3.adb (Build_Subtype, Inherit_Predicate_Flags): Move...
* sem_util.adb (Build_Subtype): Here. Add parameters for
references to objects previously declared in enclosing scopes.
(Inherit_Predicate_Flags): And here, because it is called by
Build_Subtype.
* sem_util.ads (Build_Overriding_Spec): Reorder alphabetically.
(Build_Subtype): Moved from Sem_Ch3; comments updated.
(Build_Constrained_Itype): Moved from Sem_Aggr; comments
updated.
2020-06-11 Piotr Trojanek <trojanek@adacore.com>
* sem_aggr.adb (Case_Table_Type): Change index type from Nat to
Pos.
2020-06-11 Piotr Trojanek <trojanek@adacore.com>
* sem_aggr.adb (Build_Constrained_Itype): Previously a declare
block, now a separate procedure; the only change is that now
New_Assoc_List might include components and an others clause,
which we ignore (while we deal with discriminants exactly as we
did before); extend a ??? comment about how this routine is
different from the Build_Subtype
(Resolve_Record_Aggregate): Create a constrained itype not just
for the outermost record aggregate, but for its inner record
aggregates as well.
2020-06-11 Eric Botcazou <ebotcazou@adacore.com>

otherwise such nodes are erroneously handled as semantic nodes.
Copy aspect specifications attached to nodes.
* sem_ch12.adb (Copy_Generic_Node): Protect reading attribute
Etype.
2020-06-11 Bob Duff <duff@adacore.com>
* sem_ch13.adb (Analyze_Aspect_Specifications): Do not set the
Has_Predicates flag when the Predicate_Failure aspect is seen.
It is legal (but pointless) to use this aspect without a
predicate. If we set the flag, we generate a half-baked
Predicate procedure, and if that procedure is nested, it causes
unnesting to crash.
2020-06-11 Bob Duff <duff@adacore.com>
* exp_put_image.adb (Build_Record_Put_Image_Procedure): Remove
special processing of protected types, because those are handled

doesn't work to remove the pragma, because various flags are set
during Build_Invariant_Procedure_Declaration and
Build_Invariant_Procedure_Body that need to be set to avoid the
spurious warnings.
* exp_util.adb (Make_Invariant_Call): Avoid calling the
invariant-checking procedure if the body is empty. This is an
optimization.

* libgnat/s-rident.ads: Add Jorvik to the Profile_Name
enumeration type. Add an element for Jorvik to the array
aggregate that is the initial value of the constant
Profile_Info.
* targparm.adb (Get_Target_Parameters): Handle "pragma Profile
(Jorvik);" similarly to "pragma Profile (Ravenscar);".
* snames.ads-tmpl: Declare Name_Jorvik Name_Id. Unlike
Ravenscar, Jorvik is not a pragma name and has no corresponding
element in the Pragma_Id enumeration type; this means that its
declaration must not occur between those of First_Pragma_Name

2020-06-08 Steve Baird <baird@adacore.com>
* sem_ch13.ads: Export new function
All_Membership_Choices_Static.
* sem_ch13.adb: Implement new function
All_Membership_Choices_Static. This involves moving the
functions Is_Static_Choice and All_Membership_Choices_Static,
which were previously declared within the function
Is_Predicate_Static, out to library level so that they can be
called by the new function. The already-exisiting code in
Is_Predicate_Static which became the body of
All_Membership_Choices_Static is replaced with a call to the new
function in order to avoid duplication.
* exp_ch9.adb (Is_Pure_Barrier): Several changes needed to
implement rules of AI12-0290 and RM D.7's definition of
"pure-barrier-eligible". These changes include adding a call to
the new function Sem_13.All_Membership_Choices_Static, as per
the "see 4.9" in RM D.7(1.6/5).
2020-06-08 Richard Kenner <kenner@adacore.com>
* exp_unst.adb (Visit_Node): When visiting array attribute

of the prefix, also check the actual type of the prefix.
2020-06-08 Gary Dismukes <dismukes@adacore.com>
* checks.adb (Apply_Predicate_Check): Refine test for being in a
subprogram body to account for no Corresponding_Body case,
avoiding blowups arising due to other changes here.
* exp_ch4.adb (Expand_N_Qualified_Expression): Apply predicate
checks, if any, after constraint checks are applied.
* sem_eval.ads (Check_Expression_Against_Static_Predicate): Add
Check_Failure_Is_Error formal for conditionalizing warning vs.
error messages.
* sem_eval.adb (Check_Expression_Against_Static_Predicate):
Issue an error message rather than a warning when the new
Check_Failure_Is_Error formal is True. In the nonstatic or
Dynamic_Predicate case where the predicate is known to fail,
emit the check to ensure that folded cases get checks applied.
* sem_res.adb (Resolve_Qualified_Expression): Call
Check_Expression_Against_Static_Predicate, passing True for
Check_Failure_Is_Error, to ensure we reject static predicate
violations. Remove code that was conditionally calling
Apply_Predicate_Check, which is no longer needed, and that check
procedure shouldn't be called from a resolution routine in any
case. Also remove associated comment about preventing infinite
recursion and consistency with Resolve_Type_Conversion, since
that handling was already similarly removed from
Resolve_Type_Convesion at some point.
(Resolve_Type_Conversion): Add passing of True for
Check_Failure_Is_Error parameter on call to
Check_Expression_Against_Static_Predicate, to ensure that static
conversion cases that violate a predicate are rejected as
errors.

add more regular handling of 'Priority. Remove special cases no
longer needed now that we are only checking renamings coming

2020-06-08 Claire Dross <dross@adacore.com>
* libgnat/a-cofove.adb (Insert_Space): The computation of Index
generates a spurious compiler warning about a value not being in
range for a statically dead branch. Silence it using pragma
Warnings.
2020-06-08 Bob Duff <duff@adacore.com>
* bindo-graphs.adb (function Add_Edge): Rename
Add_Edge_With_Return to Add_Edge; we can tell it returns because
it's a function, and overloading seems appropriate in this case.
If Activates_Task=True, and we're not going to add a new edge
because an existing Pred-->Succ edge already exists, then set
Activates_Task to True on the preexisting edge. This ensures
that the message:
info: use pragma Restrictions (No_Entry_Calls_In_Elaboration_Code)
appears when appropriate, no matter in what order the edges
happened to be processed.
(procedure Add_Edge): Remove redundant assertions.
(Activates_Task): Other kinds of edges can have
Activates_Task=True. For example, if we had a With_Edge and
then an Invocation_Edge with Activates_Task=True, then the
With_Edge has Activates_Task set to True.
(Add_Edge_Kind_Check): New procedure to prevent other bugs of
this nature. For example, if we were to sometimes call Add_Edge
for a Spec_Before_Body_Edge followed by Add_Edge for a
With_Edge, and sometimes in the other order, that would cause a
similar bug to what we're fixing here.
(Set_Is_Recorded_Edge): Val parameter is not used. Get rid of
it.
(Set_Activates_Task): New procedure to set the Activates_Task flag.
* bindo-graphs.ads (Library_Graph_Edge_Kind): Reorder the
enumeration literals to facilitate Add_Edge_Kind_Check.
* ali.adb (Known_ALI_Lines): The comment about "still available"
was wrong. Fix that by erasing the comment, and encoding the
relevant information in real code. Take advantage of Ada's full
coverage rules by removing "others =>". Also DRY.
2020-06-08 Ed Schonberg <schonberg@adacore.com>
