-
-2019-09-18  Ed Schonberg  <schonberg@adacore.com>

-	visible fixed-point type, which must be unique.
-
-2019-09-18  Ed Schonberg  <schonberg@adacore.com>
-
-	* sem_ch3.adb (Constrain_Component_Type): For a discriminated
-	type, handle the case of a constraint given by a conversion of a
-	discriminant of the enclosing type. Necessary when compiling a

-	Secondary_Stack component may be set by means of an aspect on
-	the task type.
-
-2019-09-18  Ed Schonberg  <schonberg@adacore.com>
-
-	* exp_aggr.adb (Expand_Record_Aggregate, Rewrite_Discriminant):
-	After rewriting a reference to an outer discriminant as a
-	selected component of the enclosing object, analyze the selected
-	component to ensure that the entity of the selector name is
-	properly set. This is necessary when the aggregate appears
-	within an expression that may have been analyzed already.
-
-2019-09-18  Justin Squirek  <squirek@adacore.com>
-
-	* sem_ch8.adb (Use_One_Type): Add guard to prevent warning on a

-	(Set_Minimum_Accessibility): Added to set new field.
-	(Minimum_Accessibility): Added to fetch new field.
-	* exp_ch6.adb (Expand_Subprogram_Call): Modify calls to fetch
-	accessibility levels to the new subprogram Get_Accessibility
-	which handles cases where minimum accessibility might be needed.
-	* sem_ch6.adb (Analyze_Subprogram_Body_Helper): Add section to
-	generate a Minimum_Accessibility object within relevant
-	subprograms.
-	* sem_util.adb, sem_util.ads (Dynamic_Accessibility_Level):
-	Additional documentation added and modify section to use new
-	function Get_Accessibility.
-	(Get_Accessibility): Added to centralize processing of
-	accessibility levels.
-
-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>
-
-	* exp_ch5.adb (Expand_Assign_Array_Loop_Or_Bitfield): The call
-	to Copy_Bitfield is now enabled.

-	Exp_Util to know the value of the Constrained attribute in the
-	static case.
-	* exp_spark.adb (Expand_SPARK_N_Attribute_Reference): Make
-	implicit dereferences inside the Constrained attribute explicit.

-	(Attribute_Constrained_Static_Value): New routine to compute the

-
-	* exp_ch6.adb (Needs_BIP_Alloc_Form): Call
-	Requires_Transient_Scope rather than checking constrainedness
-	and so forth.  We have previously improved

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

-	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.

-
-	* exp_attr.adb (Attribute_Valid): Correct the handling of

-	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.

-	* exp_disp.adb (Number_Of_Predefined_Prims): New subprogram.
-	(Make_Secondary_DT): Compute the number of predefined primitives

-	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

-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
-	Elists while in Validate_Compile_Time_Warning_Errors, because it
