2021-07-05 Steve Baird <baird@adacore.com>
* exp_ch3.adb (Build_Record_Init_Proc.Build_Assignment): When
building the assignment statement corresponding to the default
expression for a component, we make a copy of the expression.
When making that copy (and if we have seen a component that
requires late initialization), pass a Map parameter into the
call to New_Copy_Tree to redirect references to the type to
instead refer to the _Init formal parameter of the init proc.
This includes hoisting the declaration of Has_Late_Init_Comp out
one level so that it becomes available to Build_Assignment.
(Find_Current_Instance): Return True for other kinds of current
instance references, instead of just access-valued attribute
references such as T'Access.
* sem_util.adb (Is_Aliased_View): Return True for the _Init
formal parameter of an init procedure. The changes in
exp_ch3.adb can have the effect of replacing a "T'Access"
attribute reference in an init procedure with an "_Init'Access"
attribute reference. We want such an attribute reference to be
legal. However, we do not simply mark the formal parameter as
being aliased because that might impact callers.
(Is_Object_Image): Return True if Is_Current_Instance returns
True for the prefix of an Image (or related attribute) attribute
reference.

* sem_aggr.adb (Resolve_Record_Aggregate, Step_5): Do not check
for the need to use an extension aggregate for a given component
when within an instance and the type of the component hss a
private ancestor: the instantiation is legal if the generic
compiles, and spurious errors may be generated otherwise.
2021-07-05 Ghjuvan Lacambre <lacambre@adacore.com>
* errout.adb (Output_JSON_Message): Recursively call
Output_JSON_Message for continuation messages instead of
appending their content to the initial message.
2021-07-05 Steve Baird <baird@adacore.com>
* debug.adb: Remove comments about -gnatd_z switch.
* exp_ch3.adb (Make_Predefined_Primitive_Specs): A one-line fix
for a subtle bug that took some effort to debug. Append a new
Put_Image procedure for a type extension even if it seems to
already have one, just as is done for (for example) the
streaming-related Read procedure.
* exp_put_image.adb:
(Build_Record_Put_Image_Procedure.Make_Component_Attributes): Do
not treat _Parent component like just another component, for two
reasons. 1. If the _parent component's type has a
user-specified Put_Image procedure, then we want to generate a
call to that procedure and then generate extension aggregate
syntax. 2. Otherwise, we still don't want to see any mention of
"_parent" in the generated image text.
(Build_Record_Put_Image_Procedure.Make_Component_Name): Add
assertion that we are not generating a reference to an "_parent"
component.
(Build_Record_Put_Image_Procedure): Add special treatment for
null records. Add call to Duplicate_Subexpr for image attribute
prefix in order to help with expansion needed in the class-wide
case (where the prefix is also referenced in the call to
Wide_Wide_Expanded_Name) if evaluation of the prefix has side
effects. Add new local helper function, Put_String_Exp. Add
support for case where prefix type is class-wide.
(Enable_Put_Image, Preload_Root_Buffer_Type): Query Ada_Version
> Ada_2022 instead of (indirectly) querying -gnatd_z switch.
* freeze.adb (In_Expanded_Body): A one-line change to add
TSS_Put_Image to the list of subprograms that have
expander-created bodies.
* rtsfind.ads: Add support for accessing
Ada.Tags.Wide_Wide_Expanded_Name.
* sem_ch3.ads, sem_ch3.adb: Delete Is_Null_Extension function,
as part of moving it to Sem_Util.
* sem_ch13.adb
(Analyze_Put_Image_TSS_Definition.Has_Good_Profile): Improve
diagnostic messages in cases where the result is going to be
False and the Report parameter is True. Relax overly-restrictive
checks in order to implement mode conformance.
(Analyze_Stream_TSS_Definition.Has_Good_Profile): Add similar
relaxation of parameter subtype checking for the Stream
parameter of user-defined streaming subprograms.
* sem_disp.adb (Check_Dispatching_Operation): A one-line
change (and an accompanying comment change) to add TSS_Put_Image
to the list of compiler-generated dispatching primitive
operations.
* sem_util.ads, sem_util.adb: Add Ignore_Privacy Boolean
parameter to Is_Null_Record_Type function (typically the
parameter will be False when the function is being used in the
implementation of static semantics and True for dynamic
semantics; the parameter might make a difference in the case of,
for example, a private type that is implemented as a null record
type). Add related new routines Is_Null_Extension (formerly
declared in Sem_Ch3), Is_Null_Extension_Of, and
Is_Null_Record_Definition.
2021-07-05 Justin Squirek <squirek@adacore.com>
* freeze.adb (Freeze_Profile): Use N's Sloc, F_type's chars.
2021-07-05 Bob Duff <duff@adacore.com>
* checks.adb, exp_aggr.adb, exp_ch5.adb, freeze.adb,
sem_util.adb, sem_util.ads: Change L and H to be First and Last,
to match the attributes in the RM. Change calls from procedure
to function where appropriate.
2021-07-05 Bob Duff <duff@adacore.com>
* sem_util.ads, sem_util.adb (Compute_Returns_By_Ref): New
procedure to compute Returns_By_Ref, to avoid some code
duplication. This will likely change soon, so it's good to have
the code in one place.
(CW_Or_Has_Controlled_Part): Move here from Exp_Ch7, because
it's called by Compute_Returns_By_Ref, and this is a better
place for it anyway.
(Needs_Finalization): Fix comment to be vague instead of wrong.
* exp_ch6.adb (Expand_N_Subprogram_Body, Freeze_Subprogram):
Call Compute_Returns_By_Ref.
* sem_ch6.adb (Check_Delayed_Subprogram): Call
Compute_Returns_By_Ref.
* exp_ch7.ads, exp_ch7.adb (CW_Or_Has_Controlled_Part): Move to
Sem_Util.
(Has_New_Controlled_Component): Remove unused function.
2021-07-05 Ghjuvan Lacambre <lacambre@adacore.com>
* sem_ch3.adb (Check_Abstract_Overriding): Check for renamings.
2021-07-05 Boris Yakobowski <yakobowski@adacore.com>
