-
-2019-12-16  Bob Duff  <duff@adacore.com>
-
-	* sem_ch10.adb (Analyze_Subunit): Give an error if the subunit

-	* checks.adb (Apply_Float_Conversion_Check): Use node of type
-	conversion and not its parent, when inserting the declaration
-	for the temporary that hold the result of the conversion.
-	Previously the declaration was inserted above the parent of the
-	conversion, apparently as a small optimization for the

-	optimization takes place in Insert_Actions, assuming that the
-	insertion point must be above the expression that creates the
-	actions to insert.  This is not correct in the presence of
-	conditional expressions (i.e.  since Ada2012), where the
-	insertion must be in the list of actions attached to the current
-	alternative.

-
-	* sem_attr.adb (Analyze_Attribute): Use Known_RM_Size. But we

-
-	* exp_ch4.adb (Expand_N_Op_Eq.Is_Equality): Move this function

-	of "type conformant" in Ada RM 9.4(11.4/3).
-	(New_Overloaded_Entity.Has_Matching_Entry_Or_Subprogram): Add
-	new Normalized_First_Parameter_Type function to help in ignoring

-2019-09-18  Steve Baird  <baird@adacore.com>
-
-	* sem_util.ads (Interval_Lists): A new visible package. This
-	package is visible because it is also intended for eventual use
-	in Sem_Eval.Subtypes_Statically_Compatible when that function is
-	someday upgraded to handle static predicates correctly.  This
-	new package doesn't really need to be visible for now, but it
-	still seems like a good idea.
-	* sem_util.adb (Gather_Components): Implement AI12-0086 via the
-	following strategy. The existing code knows how to take a static
-	discriminant value and identify the corresponding variant; in
-	the newly-permitted case of a non-static value of a static
-	subtype, we arbitrarily select a value of the subtype and find
-	the corresponding variant using the existing code. Subsequently,
-	we check that every other value of the discriminant's subtype
-	corresponds to the same variant; this is done using the newly
-	introduced Interval_Lists package.
-	(Interval_Lists): Provide a body for the new package.
-
-2019-09-18  Javier Miranda  <miranda@adacore.com>
-
-	* exp_ch4.adb (Expand_N_Op_Eq): The frontend assumes that we can
-	do a bit-for-bit comparison of two access to protected
-	subprogram pointers. However, there are two reasons why we may
-	not be able to do that: (1) there may be padding bits for
-	alignment before the access to subprogram, and (2) the access to
-	subprogram itself may not be compared bit-for- bit because the
-	activation record part is undefined: two pointers are equal iff
-	the subprogram addresses are equal. This patch fixes it by
-	forcing a field-by-field comparison.
-	* bindgen.adb (Gen_Adainit): The type No_Param_Proc is defined
-	in the library as having Favor_Top_Level, but when we create an
-	object of that type in the binder file we don't have that
-	pragma, so the types are different. This patch fixes this issue.
-	* libgnarl/s-interr.adb, libgnarl/s-interr__hwint.adb,
-	libgnarl/s-interr__sigaction.adb, libgnarl/s-interr__vxworks.adb
-	(Is_Registered): This routine erroneously assumes that the
-	access to protected subprogram is two addresses. We need to
-	create the same record that the compiler makes to ensure that
-	any padding is the same. Then we have to look at just the first
-	word of the access to subprogram. This patch fixes this issue.

-	Storage_Size): If the expression for Storage_Size is not static
-	it may depend on characterstics of another type that may bot be

-2019-08-20  Bob Duff  <duff@adacore.com>
-
-	* exp_aggr.adb (Expand_Array_Aggregate): Use build-in-place in

-	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.

-
-	* exp_attr.adb (Expand_Loop_Entry_Attribute): When expanding a

-	that incorporates the expanded condition of the loop. The itypes

-	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

-	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

-	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

-	(avoiding spurious errors on expanded unchecked conversions
-	applied to build-in-place dispatching calls).

-
-	* 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".

-
-	* sem_ch13.adb (Object_Size): Give an error for zero. It really

-	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

-	processing to the back end in all cases where the pragma's

-	and the like. This ensures that we take advantage of whatever
-	can be compile-time known after running the back end, as opposed

-	a little duplicated code at the call site.
-	* gnat1drv.adb (Post_Compilation_Validation_Checks): Unlock the

+	for the temporary that hold the result of the conversion.
+	Previously the declaration was inserted above the parent of the

+
+2019-12-16  Bob Duff  <duff@adacore.com>
+

+	* sem_ch3.adb (Build_Derived_Type): Do not call
+	Set_Derived_Type_Link if the derived type and the parent type

+2019-12-13  Ed Schonberg  <schonberg@adacore.com>
+

+
+2019-12-12  Ed Schonberg  <schonberg@adacore.com>
+

+
+2019-09-18  Steve Baird  <baird@adacore.com>
+
+	* sem_util.ads (Interval_Lists): A new visible package. This
+	package is visible because it is also intended for eventual use
+	in Sem_Eval.Subtypes_Statically_Compatible when that function is
+	someday upgraded to handle static predicates correctly.  This
+	new package doesn't really need to be visible for now, but it
+	still seems like a good idea.
+	* sem_util.adb (Gather_Components): Implement AI12-0086 via the
+	following strategy. The existing code knows how to take a static
+	discriminant value and identify the corresponding variant; in
+	the newly-permitted case of a non-static value of a static
+	subtype, we arbitrarily select a value of the subtype and find
+	the corresponding variant using the existing code. Subsequently,
+	we check that every other value of the discriminant's subtype
+	corresponds to the same variant; this is done using the newly
+	introduced Interval_Lists package.
+	(Interval_Lists): Provide a body for the new package.
+
+2019-09-18  Javier Miranda  <miranda@adacore.com>
+
+	* exp_ch4.adb (Expand_N_Op_Eq): The frontend assumes that we can
+	do a bit-for-bit comparison of two access to protected
+	subprogram pointers. However, there are two reasons why we may
+	not be able to do that: (1) there may be padding bits for
+	alignment before the access to subprogram, and (2) the access to
+	subprogram itself may not be compared bit-for- bit because the
+	activation record part is undefined: two pointers are equal iff
+	the subprogram addresses are equal. This patch fixes it by
+	forcing a field-by-field comparison.
+	* bindgen.adb (Gen_Adainit): The type No_Param_Proc is defined
+	in the library as having Favor_Top_Level, but when we create an
+	object of that type in the binder file we don't have that
+	pragma, so the types are different. This patch fixes this issue.
+	* libgnarl/s-interr.adb, libgnarl/s-interr__hwint.adb,
+	libgnarl/s-interr__sigaction.adb, libgnarl/s-interr__vxworks.adb
+	(Is_Registered): This routine erroneously assumes that the
+	access to protected subprogram is two addresses. We need to
+	create the same record that the compiler makes to ensure that
+	any padding is the same. Then we have to look at just the first
+	word of the access to subprogram. This patch fixes this issue.
+
+2019-09-18  Bob Duff  <duff@adacore.com>

+
+2019-08-20  Bob Duff  <duff@adacore.com>
+
+	* exp_ch6.adb (Needs_BIP_Alloc_Form): Call

+	* sem_ch4.adb (Analyze_Allocator): The above change causes the

+
+2019-08-20  Bob Duff  <duff@adacore.com>
+
+	* freeze.adb (Is_Atomic_VFA_Aggregate): Make the temp for

+
+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

+
+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.

+	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.

+	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

+
+2019-08-14  Bob Duff  <duff@adacore.com>
+

+	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
