pragma Inline.
* bindo-graphs.adb (Delete_Edge): Fix layout in parameter list.
2019-08-21 Gary Dismukes <dismukes@adacore.com>
* exp_ch3.adb (Build_Master): Suppress call to
Build_Class_Wide_Master in the case where the
access-to-limited-class-wide type was created for a component in
an entry's formal parameter
block (Is_Parameter_Block_Component_Type), to prevent a master
from being created for such access types generated by the front
end in a task spec for entry formals in a parameter block. Add
a ??? about whether this suppression should be done more
generally (such as by using Comes_From_Source).
2019-08-21 Eric Botcazou <ebotcazou@adacore.com>
* exp_ch6.adb (Expand_N_Extended_Return_Statement): In the case
of a built-in-place function that doesn't need a BIP_Alloc_Form
parameter but returns unconstrained, build the return
consistently using the function's result subtype. Remove bypass
added in previous change.
2019-08-21 Piotr Trojanek <trojanek@adacore.com>

subtypes of private protected types.
2019-08-21 Piotr Trojanek <trojanek@adacore.com>

2019-08-21 Justin Squirek <squirek@adacore.com>
* doc/gnat_rm/implementation_defined_pragmas.rst: Modify
documentation to reflect expected behavior.
* gnat_rm.texi: Regenerate.
* sem_prag.adb (Analyze_Pragma): Modify handling of pragma
Max_Entry_Queue_Length to not reject integer values of negative
one.
* sem_util.adb (Get_Max_Queue_Length): Add processing for values
of negative one to fit within the current scheme.
2019-08-20 Arnaud Charlet <charlet@adacore.com>
* exp_unst.adb (Unnest_Subprograms, Unnest_Subprogram): Take
inlining (-gnatn) into account.
2019-08-20 Ed Schonberg <schonberg@adacore.com>
* exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case
Storage_Size): If the expression for Storage_Size is not static
it may depend on characterstics of another type that may bot be
frozen yet, so the elaboration of the expression for the aspect
must be attached directly to the freeze actions of the type to
which it applies.
2019-08-20 Piotr Trojanek <trojanek@adacore.com>
* exp_util.adb (Build_DIC_Procedure_Declaration): Set the last
entity of the generated Default_Initial_Condition procedure in
order to construct a proper entity chain.

* exp_spark.adb (Expand_SPARK_N_Slice_Or_Indexed_Component):
Renaming of function to apply to slices as well.
(Expand_SPARK): Expand prefix of slices of access type.
2019-08-20 Bob Duff <duff@adacore.com>
* exp_aggr.adb (Expand_Array_Aggregate): Use build-in-place in
the nonlimited case in STEP 4. This improves the efficiency of
things like (1 .. 1000 => <>). We still generate some code for
that, unfortunately, but it is much improved.
(Aggr_Assignment_OK_For_Backend): Return false if <> components
are present.
2019-08-20 Bob Duff <duff@adacore.com>
* exp_ch6.adb (Needs_BIP_Alloc_Form): Call
Requires_Transient_Scope rather than checking constrainedness
and so forth. We have previously improved
Requires_Transient_Scope to return False in various cases,
notably a limited record with an access discriminant. This
change takes advantage of that to avoid using the secondary
stack for functions returning such types.
(Make_Build_In_Place_Call_In_Allocator): Be consistent by
calling Needs_BIP_Alloc_Form rather than Is_Constrained and so
forth.
* sem_ch4.adb (Analyze_Allocator): The above change causes the
compiler to generate code that is not legal Ada, in particular
an uninitialized allocator for indefinite subtype. This is
harmless, so we suppress the error message in this case.
2019-08-20 Gary Dismukes <dismukes@adacore.com>

* adaint.c (__gnat_to_gm_time): On _WIN32, don't round time up
to even second.
2019-08-20 Ed Schonberg <schonberg@adacore.com>
* sem_ch3.adb (Analyze_Object_Declaration): If actual type is
private and distinct from nominal type in declaration, propagate
flags Is_Constr_Subt_For_U_Nominal and _UN_Aliased to full view
of private type.
2019-08-20 Ed Schonberg <schonberg@adacore.com>
* exp_attr.adb (Expand_Loop_Entry_Attribute): When expanding a
loop entry attribute for a while_loop we construct a function
that incorporates the expanded condition of the loop. The itypes
that may be generated in that expansion must carry the scope of
the constructed function for proper handling in gigi.
2019-08-20 Ed Schonberg <schonberg@adacore.com>
* exp_disp.adb (Build_Class_Wide_Check, Replace_Formals): When a
dispatching call tp a subprogram with a class-wide precondition
occurrs in the same declarative part as the ancestor subprogram
being called, the`expression for the precondition has not been
analyzed yet. Such a call may appear, e.g. in an expression
function. In that case, the replacement of formals by actuals in
the call cannot use the formal entities of the subprogram being
called, and the occurrence of the formals in the expression must
be located by name (Chars fields) as would be done at a later
freeze point, when the expression is resolved in the context of
the subprogram itself.
2019-08-20 Bob Duff <duff@adacore.com>
* sem_prag.adb (Persistent_BSS): If an initialization is present
because of Initialize_Scalars or Normalize_Scalars, generate an
implicit pragma Suppress_Initialization to remove that, because
initialization is not allowed for these variables. Other
initializations remain illegal.
2019-08-20 Gary Dismukes <dismukes@adacore.com>
* sem_ch3.adb (OK_For_Limited_Init_In_05): In the case of type
conversions, apply the recursive call to the Original_Node of
the expression Exp rather than the Expression of the
Original_Node, in the case where Exp has been rewritten;
otherwise, when Original_Node is the same as Exp, apply the
recursive call to the Expression.
(Check_Initialization): Revise condition for special check on
type conversions of limited function calls to test Original_Node
(avoiding spurious errors on expanded unchecked conversions
applied to build-in-place dispatching calls).
2019-08-20 Patrick Bernardi <bernardi@adacore.com>
* exp_aggr.adb (Expand_Record_Aggregate): Always convert a
record Aggregate to assignment statements if the option
Aggregate_Individually_Assign is set.
* opt.ads (Aggregate_Individually_Assign): New option.
* par-prag.adb (Prag): Add Pragma_Aggregate_Individually_Assign.
* sem_prag.adb (Analyze_Pragma): Likewise.
* snames.ads-tmpl: Add Pragma_Aggregate_Individually_Assign and
Name_Aggregate_Individually_Assign.
* doc/gnat_rm/implementation_defined_pragmas.rst: Document
pragma Aggregate_Individually_Assign.
* gnat_rm.texi: Regenerate.
2019-08-20 Bob Duff <duff@adacore.com>
* par-ch4.adb: Minor wording change in error messages.
* sem_aggr.adb (Resolve_Delta_Aggregate): Emit an error for Ada
versions prior to Ada 2020.
2019-08-20 Bob Duff <duff@adacore.com>
* freeze.adb (Is_Atomic_VFA_Aggregate): Make the temp for
initialization of the atomic variable be constant. This is
cleaner, and might improve efficiency.
2019-08-20 Eric Botcazou <ebotcazou@adacore.com>
* repinfo.adb (List_Record_Info): In -gnatR4 mode, set the
relevant flag on the implicit base type of a record subtype.
2019-08-20 Bob Duff <duff@adacore.com>
* sem_eval.adb (Expr_Value): Implement the case of an unchecked
conversion of a static expression.
2019-08-20 Bob Duff <duff@adacore.com>
* sem_ch13.adb (Is_Null_Array): New function, used to detect the
null array case; used to warn about uncheckedly converting to a
zero-sized array. It is unfortunate that we can't just check
the size, and warn on all cases of converting from a
nonzero-sized type to a zero-sized one. That's because "0" means
two different things: "size is zero" and "size is unknown".
Until we fix that design flaw, we need this more targeted fix.
2019-08-20 Bob Duff <duff@adacore.com>
* libgnat/a-cborma.adb, libgnat/a-cborse.adb (Clear): Repeatedly
call Delete. This avoids clearing the free list, which
substantially speeds up future Delete operations.
2019-08-20 Bob Duff <duff@adacore.com>
* sem_ch13.adb (Component_Order_Check): New procedure to check
for out-of-order clauses.
* warnsw.ads, warnsw.adb: New -gnatw_r switch.
* doc/gnat_ugn/building_executable_programs_with_gnat.rst:
Document new switch.
* gnat_ugn.texi: Regenerate.
2019-08-20 Bob Duff <duff@adacore.com>
* sem_ch13.adb (Object_Size): Give an error for zero. It really
rubs me the wrong way that we don't honor "for T'Object_Size use
0;", but it's not important enough to fix. In any case, if we're
not going to obey the clause, we should give an error.
2019-08-20 Bob Duff <duff@adacore.com>
* errout.adb (Error_Msg_Internal): Set Warn_Err in case of
Is_Style_Msg.
* erroutc.adb (Output_Msg_Text): Do Warnings_Treated_As_Errors
processing and [warning-as-error] modification for style
messages. Clean up code, simplify, remove unnecessary block
statement, add renaming of table entry.
* erroutc.ads (Warning_Treated_As_Error): Fix comment: no such
thing as Set_Warning_As_Error.
* opt.ads: Clean up comments and move related declarations near
each other.
* par-prag.adb: Process Warning_As_Error. This is necessary
because many style warning happen during parsing.
* sem_prag.adb: Use new Acquire_Warning_Match_String.
* sem_util.ads, sem_util.adb (Acquire_Warning_Match_String): New
function shared by par-prag.adb and sem_prag.adb. Replaces the
procedure in sem_prag.adb. Avoid use of global variables.
* stringt.ads, stringt.adb (To_String): New function to convert
String_Id to String.
* doc/gnat_rm/implementation_defined_pragmas.rst: Document the
new feature.
* gnat_rm.texi: Regenerate.

(Is_Loaded): Reimplement using a lookup in the names table.
(Remove_Unit): Unregister the name.
(Unit_Name_Hash): New function.
* lib-load.adb (Create_Dummy_Package_Unit): Call Init_Unit_Name.
(Load_Unit): Use a lookup in the names table to find out whether
the unit has already been loaded. Call Init_Unit_Name and then
Remove_Unit if the loading has failed.
(Make_Child_Decl_Unit): Call Init_Unit_Name.
(Make_Instance_Unit): Likewise.

private types where the full type is modular. System.Address is
an example. Otherwise, we convert uncheckedly to a signed type,
so we get an incorrect range 0 .. -1, for which all values will
fail. The 'Valid attribute is illegal for such types, but we
generate such illegal attribute_references for 'Valid_Scalars,
and we generate 'Valid_Scalars when the -gnateV switch is used.
Rename Btyp --> PBtyp to avoid hiding the outer Btyp, which was
confusing.

inherited from the parent type.
* exp_disp.adb (Number_Of_Predefined_Prims): New subprogram.
(Make_Secondary_DT): Compute the number of predefined primitives
of all tagged types (including tagged types not defined at
library level). Previously we unconditionally relied on the
Max_Predef_Prims constant value when building the dispatch
tables of tagged types not defined at library level (thus
consuming more memory for their dispatch tables than required).

* sem_prag.ads, sem_prag.adb
(Process_Compile_Time_Warning_Or_Error): In parameterless
version, improve detection of whether we are in a generic unit
to cover the case of an instance within a generic unit.
(Process_Compile_Time_Warning_Or_Error): Rename the
two-parameter version to be
Validate_Compile_Time_Warning_Or_Error, and do not export it.
Issue a warning if the condition is not known at compile time.
The key point is that the warning must be given only for pragmas
deferred to the back end, because the back end discovers
additional values that are known at compile time. Previous
changes in this ticket have enabled this by deferring to the
back end without checking for special cases such as 'Size.
(Validate_Compile_Time_Warning_Or_Error): Rename to be
Defer_Compile_Time_Warning_Error_To_BE.
* warnsw.ads, warnsw.adb (Warn_On_Unknown_Compile_Time_Warning):

2019-08-14 Bob Duff <duff@adacore.com>
* sem_prag.adb (Process_Compile_Time_Warning_Or_Error): Defer
processing to the back end in all cases where the pragma's
condition is not known at compile time during the front end
(except in generics), as opposed to detecting 'Size attributes
and the like. This ensures that we take advantage of whatever
can be compile-time known after running the back end, as opposed
to having the front end guess what the back end can do. Remove
a little duplicated code at the call site.
* gnat1drv.adb (Post_Compilation_Validation_Checks): Unlock the
Elists while in Validate_Compile_Time_Warning_Errors, because it
does analysis and name resolution, which sometimes involves
adding Elists.

(Add_Inlined_Body): Bail out early for subprograms in the main
unit or subunit. Likewise if the Is_Called flag is set. If the
subprogram is an instance, invoke Add_Inlined_Instance. Call
Set_Is_Called earlier. If the subrogram is within an instance,
invoke Add_Inlined_Instance. Also deal with the case where the
call itself is within an instance.
(Add_Inlined_Instance): New procedure.
(Add_Inlined_Subprogram): Remove conditions always fulfilled.
(Add_Pending_Instantiation): Move the defence against ludicruous
number of instantiations to here. When back-end inlining is
enabled, associate an instantiation with its index in table and
mark a few selected kinds of instantiations as always needed.
(Initialize): Set Backend_Instances to No_Elist.

* sem_prag.adb (Validate_Compile_Time_Warning_Error): Attach the
warning to the Sloc of the first pragma argument, rather than to
the pragma itself. This is to make pragmas processed after the
back end use the same Sloc as pragmas processed earlier, in the
front end. There's no reason for this discrepancy, and it
hinders further work on this ticket.

analysis. Error messages for failed aliasing checks are only
output in this case.

removed as duplicates of marking errors. Components are stored
in the permission map using their original component to avoid
inconsistencies between components of different views of the
same type.
