53
54	* exp_ch4.adb (Expand_N_In): Do not replace a membership test on a
55	scalar type with a validity test when the membership appears in a
56	predicate expression, to prevent a spurious error when predicate is
57	specified static.
58	* sem_ch13.adb (Build_Predicate_Functions): Add warning if a static

60	redundant.

155	* sem_prag.adb (Analyze_Part_Of): The context-specific portion of the
156	analysis is now directed to several specialized routines.
157	(Check_Part_Of_Abstract_State): New routine.

215
2162017-12-15  Bob Duff  <duff@adacore.com>
217
218	* exp_ch6.adb (Expand_N_Extended_Return_Statement,
219	Expand_Simple_Function_Return): Assert that the b-i-p-ness of the

221	changes to allow b-i-p calls non-b-i-p, and vice versa.
222
2232017-12-15  Ed Schonberg  <schonberg@adacore.com>
224
225	* exp_unst.adb (Unnest_Subprograms): Nothing to do if the main unit is
226	a generic package body. Unnesting is only an issue when generating
227	code, and if the main unit is generic then nested instance bodies have
228	not been created and analyzed, and unnesting will crash in the absence
229	of those bodies,
230
2312017-12-15  Hristian Kirtchev  <kirtchev@adacore.com>
232
233	* inline.adb (Add_Inlined_Body): Do not add a function which is
234	completed by an expression function defined in the same context as the
235	initial declaration because the completing body is not in a package
236	body.
237	(Is_Non_Loading_Expression_Function): New routine.
238
2392017-12-15  Hristian Kirtchev  <kirtchev@adacore.com>

242	the behavior of -gnatdL from before revision 255412.
243	* sem_elab.adb: Update the section of compiler switches.
244	(Build_Call_Marker): Do not create a marker for a call which originates
245	from an expanded spec or body of an instantiated gener, does not invoke
246	a generic formal subprogram, the target is external to the instance,
247	and -gnatdL is in effect.
248	(In_External_Context): New routine.
249	(Process_Conditional_ABE_Activation_Impl): Update the uses of -gnatdL
250	and associated flag.
251	(Process_Conditional_ABE_Call): Update the uses of -gnatdL and

256
2572017-12-15  Ed Schonberg  <schonberg@adacore.com>
258
259	* sem_ch6.adb (Possible_Freeze): Do not set Delayed_Freeze on an
260	subprogram instantiation, now that the enclosing wrapper package
261	carries an explicit freeze node. THis prevents freeze nodes for the
262	subprogram for appearing in the wrong scope. This is relevant when the
263	generic subprogram has a private or incomplete formal type and the
264	instance appears within a package that declares the actual type for the
265	instantiation, and that type has itself a delayed freeze.
266
2672017-12-15  Patrick Bernardi  <bernardi@adacore.com>
268
269	* doc/gnat_ugn/gnat_and_program_execution.rst: Removed references to

271	Checking section as it is no longer used by any of our supported
272	targets.
273
2742017-12-15  Bob Duff  <duff@adacore.com>
275
276	* exp_ch6.adb (Expand_N_Extended_Return_Statement): If the
277	Init_Assignment is rewritten, we need to set Assignment_OK on the new
278	node.  Otherwise, we will get spurious errors when initializing via
279	assignment statement.
280
2812017-12-15  Arnaud Charlet  <charlet@adacore.com>
282
283	* exp_unst.adb (Visit_Node): Refine handling of 'Access to ignore non
284	relevant nodes.

292
2932017-12-15  Bob Duff  <duff@adacore.com>
294
295	* exp_ch7.adb (Expand_Cleanup_Actions): Make sure the block and handled
296	statement sequence generated for certain extended return statements
297	have a Sloc that is not No_Location. Otherwise, the back end doesn't
298	set any location and ends up reading uninitialized variables.
299
3002017-12-15  Bob Duff  <duff@adacore.com>
301

329	* gcc-interface/trans.c (Attribute_to_gnu) <Attr_Size>: Make sure to
330	apply the exception for padded objects to the type of the object.
331	* gcc-interface/utils.c (hash_pad_type): New static function.
332	(lookup_and_insert_pad_type): Rename into...
333	(canonicalize_pad_type): ...this.  Call hash_pad_type, do only one
334	lookup with insertion and always return the canonical type.
335	(maybe_pad_type): Adjust to above changes.  Set debug type later.
336	(pad_type_has_rm_size): New predicate.

3842017-12-05  Jerome Lambourg  <lambourg@adacore.com>
385
386	* libgnarl/s-taprop__qnx.adb: Better detect priority ceiling bug in
387	QNX.  At startup, the first mutex created has a non-zero ceiling
388	priority whatever its actual policy. This makes some tests fail
389	(c940013 for example).

392
393	* exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Call
394	Expand_Cleanup_Actions for N_Extended_Return_Statement.
395	* exp_ch7.adb (Expand_Cleanup_Actions): Handle
396	N_Extended_Return_Statement by transforming the statements into a
397	block, and (indirectly) calling Expand_Cleanup_Actions on the block.
398	It's too hard for Expand_Cleanup_Actions to operate directly on the
399	N_Extended_Return_Statement, because it has a different structure than
400	the other node kinds that Expand_Cleanup_Actions.
401	* exp_util.adb (Requires_Cleanup_Actions): Add support for
402	N_Extended_Return_Statement.  Change "when others => return False;" to
403	"when others => raise ...;" so it's clear what nodes this function
404	handles.  Use named notation where appropriate.
405	* exp_util.ads: Mark incorrect comment with ???.

462	* terminals.c (__gnat_setup_child_communication): As documented,
463	__gnat_setup_child_communication should not terminate - it is intended
464	to be used as the child process of a call to fork().  However, execvp
465	might actually return in some cases, for instance when attempting to
466	run a 32-bit binary on a 64-bit Linux distribution when the
467	compatibility packages are not installed. In these cases, exit the

656	* exp_aggr.adb (Gen_Assign): Do not analyze the expressionn of the
657	assignment if it is part of an Iterated_Component_Association: the
658	analysis needs to take place once the loop structure is analyzed and
659	the loop parameter made visible, because references to it typically
660	appear in the corresponding expression.  This is necessary if the
661	expression is an aggregate, because previous pre-analysis of the
662	expression does not handle nested aggregates properly.

690	computation of address passed to Symbolic_Address for symbolization.

1318	* sem_ch6.adb (Analyze_Function_Return): Default initialize Obj_Decl,

1372
1373	* namet.ads, namet.adb (Valid_Name_Id): New subtype that excludes
1374	Error_Name and No_Name.  Use this (versus Name_Id) to indicate which
1375	objects can have those special values. Valid_Name_Id could usefully be
1376	used all over the compiler front end, but that's too much trouble for
1377	now. If we did that, we might want to rename:
1378	Name_Id --> Optional_Name_Id, Valid_Name_Id --> Name_Id.
1379	For parameters of type Valid_Name_Id, remove some redundant tests,
1380	including the ones found by CodePeer.  Use Is_Valid_Name instead of

2934	* exp_ch6.adb (Expand_Call_Helper): Handle case of build-in-place
2935	functions returning nonlimited types. Allow for qualified expressions
2936	and type conversions.
2937	(Expand_N_Extended_Return_Statement): Correct the computation of
2938	Func_Bod to allow for child units.
2939	(Expand_Simple_Function_Return): Remove assumption that b-i-p implies
2940	limited (initialization of In_Place_Expansion), and implies >= Ada
2941	2005.
2942	(Is_Build_In_Place_Result_Type): New function to accompany
2943	Is_Build_In_Place_Function and Is_Build_In_Place_Function_Call, because
2944	sometimes we just have the type on our hands, not the function.  For
2945	now, does the same thing as the old version, so build-in-place is
2946	disabled for nonlimited types, except that you can use -gnatd.9 to
2947	enable it.
2948	* exp_ch6.ads (Is_Build_In_Place_Result_Type): New function to
2949	accompany Is_Build_In_Place_Function and
2950	Is_Build_In_Place_Function_Call, because sometimes we just have the
2951	type on our hands, not the function.
2952	(Make_Build_In_Place_Call_In_...): Handle nonlimited build-in-place
2953	cases.
2954	(Make_Build_In_Place_Call_In_Object_Declaration): Remove the
2955	questionable code at the end that was setting the Etype.
2956	* exp_aggr.adb (Is_Build_In_Place_Aggregate_Return): New function to
2957	determine whether "return (...agg...);" is returning from a
2958	build-in-place function.
2959	(Initialize_Ctrl_Array_Component, Initialize_Ctrl_Record_Component):
2960	Remove assumption that b-i-p implies limited (initialization of
2961	In_Place_Expansion).
2962	(Build_Record_Aggr_Code): AI-287: fix comment; it can't be wrapped in
2963	an unchecked conversion.  Add assertions.
2964	(Convert_Aggr_In_Object_Decl): Establish_Transient_Scope -- no need for
2965	secondary stack here, just because the type needs finalization.  That
2966	code is obsolete.
2967	(Convert_To_Assignments): Only set Unc_Decl if Nkind (N) = N_Aggregate.
2968	For "return (...agg...);" don't assume b-i-p implies limited.
2969	Needs_Finalization does not imply secondary stack.
2970	(Expand_Array_Aggregate): Named notation.  Reverse the sense of
2971	Component_OK_For_Backend -- more readability with fewer double
2972	negatives.
2973	* exp_attr.adb (Expand_N_Attribute_Reference): Remove assumptions that
2974	b-i-p implies >= Ada 2005.
2975	* exp_ch3.adb (Expand_N_Object_Declaration): Remove assumptions that
2976	b-i-p implies >= Ada 2005.  Remove Adjust if we're building the return
2977	object of an extended return statement in place.

2983	* exp_ch7.adb: Comment fix.
2984	* exp_ch8.adb (Expand_N_Object_Renaming_Declaration): Remove
2985	assumptions that b-i-p implies >= Ada 2005.
2986	* exp_disp.adb (Expand_Interface_Actuals): Remove assumptions that
2987	b-i-p implies >= Ada 2005.
2988	* exp_util.adb (Build_Allocate_Deallocate_Proc): Look at Storage_Pool
2989	(Expr), in case Pool_Id is not set.
2990	(Initialized_By_Aliased_BIP_Func_Call): Handle case where the call is
2991	qualified or converted.
2992	(Is_Secondary_Stack_BIP_Func_Call): Don't check if Nkind (Selector_Name
2993	(Param)) = N_Identifier; that's all it could be.
2994	* sinfo.ads: Comment fixes.
2995	* snames.ads-tmpl: Comment fixes.
2996	* debug.adb: Add flag gnatd.9, to enable the build-in-place machinery.

3027
3028	* sem_ch6.adb (Analyze_Expression_Function): Do not emit freeze nodes
3029	for types in expression if the function is within a generic unit.
3030	* sem_res.adb (Resolve): In a generic context do not freeze an

3987	* sem_ch12.adb (Analyze_Subprogram_Instantiation):
3988	Set SPARK_Mode from spec when set, for analysis
3989	of instance. Restore after analysis of instance.
3990	(Instantiate_Subprogram_Body): Set SPARK_Mode from body when
3991	set, for analysis of body instance. Restored automatically at
3992	the end of the subprogram.
3993	* gnat1drv.adb (Adjust_Global_Switches): Set
3994	Check_Validity_Of_Parameters to False in GNATprove mode.
3995	* opt.ads (Check_Validity_Of_Parameters): Document switch to

4014
4015	* sprint.adb (Write_Corresponding_Source): Ignore if there is
4016	no current source file.
4017	(Write_Name_With_Col_Check, Write_Name_With_Col_Check_Sloc):
4018	Print something helpful in case N is invalid.

4020
40212017-09-08  Eric Botcazou  <ebotcazou@adacore.com>

4034
40352017-09-08  Yannick Moy  <moy@adacore.com>
4036
4037	* sem_aggr.adb (Resolve_Record_Aggregate):
4038	Rewrite bounds of aggregate subexpressions which may depend on

4042
4043	* sem_ch5.adb: Prevent assertion failure on illegal code.
4044

4046
4047	* lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
4048	calling Renamed_Entity on an entity which cannot be a renaming.
4049
40502017-09-08  Eric Botcazou  <ebotcazou@adacore.com>
4051
4052	* exp_aggr.adb: Add with & use clause for Urealp.
4053	(Aggr_Assignment_OK_For_Backend): Accept (almost all)
4054	elementary types instead of just discrete types.
4055	* sem_eval.adb (Expr_Value): Deal with N_Null for access types.
4056	* gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
4057	Be prepared for the FP zero value in the memset case.  Add small

4059
40602017-09-08  Eric Botcazou  <ebotcazou@adacore.com>
4061
4062	* s-htable.adb (Static_HTable.Reset): Use aggregate instead
4063	of loop.
4064
40652017-09-08  Hristian Kirtchev  <kirtchev@adacore.com>
4066
4067	* exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
4068	of New_Copy because the latter leaves the syntactic structure of
4069	the tree inconsistent (a child is accessible through two parents)
4070	and prevents proper replication of itypes by subsequent calls
4071	to New_Copy_Tree.
4072	* exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
4073	New_Copy because the latter leaves the syntactic structure of the
4074	tree inconsistent (a child is accessible through two parents)
4075	and prevents proper replication of itypes by subsequent calls
4076	to New_Copy_Tree.
4077	* sem_util.adb (In_Subtree): New routine.
4078	(New_Copy_Tree): Reimplemented.
4079	* sem_util.ads (In_Subtree): New routine.
4080	(New_Copy_Tree): Reimplemented.
4081
40822017-09-08  Ed Schonberg  <schonberg@adacore.com>
4083
4084	* sem_ch13.adb (Resolve_Aspect_Expressions): The expression
4085	for aspect Default_Value is a static scalar value, but it does
4086	not freeze the type. Yhis allows for subsequent representation
4087	clauses for the type.
4088
40892017-09-08  Javier Miranda  <miranda@adacore.com>
4090
4091	* sem_ch8.adb (Find_Direct_Name.Undefined): Do

4093	compiling with errors ignored.
4094
40952017-09-08  Ed Schonberg  <schonberg@adacore.com>
4096
4097	* sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
4098	check if the instance is within an enclosing instance body. The
4099	formal package was legal in the enclosing generic, and is
4100	legal in the enclosing instantiation.  This optimisation may be
4101	applicable elsewhere, and it also removes spurious errors that
4102	may arise with on-the-fly processing  of instantiations that
4103	contain Inline_Always subprograms.
4104
41052017-09-08  Vincent Celier  <celier@adacore.com>
4106
4107	* gnatcmd.adb: Disregard empty argument of GNAT driver.

4117
41182017-09-08  Justin Squirek  <squirek@adacore.com>
4119
4120	* switch-c.adb (Scan_Front_End_Switches): Add new warning switch
4121	case to handle underscore flags.
4122	* warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
4123	new procedure to handle underscores.
4124
41252017-09-08  Javier Miranda  <miranda@adacore.com>
4126
4127	* exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
4128	divisions with fixed point results to avoid generating twice
4129	the runtime check on divide by zero.
4130	* checks.adb (Apply_Divide_Checks): Ensure that operands are
4131	not evaluated twice (once for their runtime checks and once for
4132	their regular computation).
4133
41342017-09-08  Yannick Moy  <moy@adacore.com>
4135
4136	* sem_prag.adb (Analyze_Part_Of): Add missing
4137	return statements after issuing errors.  Add detection of
4138	out-of-order item and single concurrent type.

4621	* repinfo.adb (List_Record_Info): Split implementation into...
4622	(Compute_Max_Length): ...this.	Recurse on records if requested.
4623	(List_Record_Layout): Likewise.
4624	* switch-c.adb (Scan_Front_End_Switches) <'R'>: Use case
4625	statement, accept '0' and set List_Representation_Info_Extended
4626	on 'e'.
4627	* usage.adb (Usage): Document new -gnatRe variant.
4628
46292017-09-08  Ed Schonberg  <schonberg@adacore.com>
4630
4631	* sem_prag.adb (Analyze_Pragma, case Default_Storage_Pool):
4632	Do not save the given entity in the global variable Default_Pool
4633	if the pragma appears within a generic unit.
4634
46352017-09-08  Bob Duff  <duff@adacore.com>
4636
4637	* errout.adb (Delete_Warning): Do not
4638	decrement Warnings_Treated_As_Errors. This is called before
4639	Warnings_Treated_As_Errors has been incremented to account for
4640	this warning. Decrementing it here can lead to negative values
4641	of Warnings_Treated_As_Errors, raising Constraint_Error in
4642	checks-on builds, and causing the compiler to return an error
4643	code in checks-off builds.
4644
46452017-09-08  Arnaud Charlet  <charlet@adacore.com>
4646
4647	* sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
4648	entities of named concurrent types as Ref_Id and not of anonymous
4649	concurrent objects (because callers already know when a conversion
4650	is necessary and can easily do it); also, do not expect protected
4651	types or protected objects as Context_Id (because no flow-related
4652	SPARK pragmas are attached there); reflect these changes in a
4653	more precise comment.
4654
46552017-09-08  Olivier Hainque  <hainque@adacore.com>
4656
4657	* g-altive.ads: Add documentation.
4658
46592017-09-08  Bob Duff  <duff@adacore.com>
4660
4661	* sem_util.ads, debug.adb: Minor comment fix.

4663
46642017-09-08  Ed Schonberg  <schonberg@adacore.com>
4665
4666	* sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
4667	for compatibility of component types of formal and actual in an
4668	instantiation of a child unit,	when the component type of the
4669	formal is itself a formal of an enclosing generic.
4670
46712017-09-08  Arnaud Charlet  <charlet@adacore.com>
4672
4673	* sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
4674	sem_prag.adb to make it available for GNATprove; for concurrent
4675	types replace custom scope climbing with Scope_Same_Or_Within; for
4676	single concurrent objects add scope climbing (with Scope_Within),
4677	which was not there (that's the primary semantic change of this
4678	commit); also, when comparing a single concurrent object with
4679	its corresponding concurrent type rely on equality of types,
4680	not of objects (because that's simpler to code).
4681	* sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
4682	(Analyze_Global_Item): adjust special-casing of references to the
4683	current instance of a concurrent unit in the Global contracts
4684	of task types and single tasks objects; similar for references
4685	in the protected operations and entries of protected types and
4686	single protected objects (in all these cases the current instance
4687	behaves as an implicit parameter and must not be mentioned in
4688	the Global contract).
4689
46902017-09-08  Arnaud Charlet  <charlet@adacore.com>
4691
4692	* exp_ch6.adb (Expand_Call_Helper): Introduce temporary for

4695
46962017-09-08  Ed Schonberg  <schonberg@adacore.com>
4697
4698	* sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded
4699	name that designates the current instance of a child unit in its
4700	own body and appears as the prefix of a reference to an entity
4701	local to the child unit.
4702	* exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
4703	Minor reformatting.
4704

4716
4717	* sem_ch3.adb (Build_Derived_Private_Type): Inherit
4718	representation items from interfaces that the derived type
4719	implements, not just from the parent type.
4720	* sem_util.ads, sem_util.adb (Abstract_Interface_List): Change
4721	this to return an empty list when there are no interfaces.
4722	* einfo.ads, sem_ch13.adb: Minor comment fixes.
4723	* sem_attr.adb: Minor comment fix.
4724
47252017-09-08  Doug Rupp  <rupp@adacore.com>

4731
4732	* exp_ch4.adb (Expand_N_Allocator): Generate a
4733	call to Allocate_Any_Controlled when the allocation does not
4734	require any initialization.
4735
47362017-09-08  Hristian Kirtchev  <kirtchev@adacore.com>
4737
4738	* sem_util.adb (Copy_Node_With_Replacement):
4739	Update the Renamed_Object field of a replicated object renaming
4740	declaration.
4741
47422017-09-08  Patrick Bernardi  <bernardi@adacore.com>
4743
4744	* exp_ch9.adb (Is_Pure_Barrier): Allow type
4745	conversions and components of objects. Simplified the detection
4746	of the Count attribute by identifying the corresponding run-time
4747	calls.
4748
47492017-09-08  Yannick Moy  <moy@adacore.com>

4751	* exp_ch9.adb, exp_disp.adb, repinfo.adb, sem_ch12.adb, sem_dim.adb,

4753
47542017-09-08  Ed Schonberg  <schonberg@adacore.com>
4755
4756	* freeze.adb (Has_Incomplete_Compoent): New predicate, subsidiary
4757	of Freeze_Profile, used to inhibit the freezing of the profile
4758	of an expression function declared within a nested package, when
4759	some type in the profile depends on a private type declared in
4760	an enclosing package.
4761
47622017-09-08  Bob Duff  <duff@adacore.com>
4763
4764	* gnat1drv.adb (Gnat1drv): Do not set the Force_ALI_Tree_File flag in
4765	the subunit case. It's still OK to set it in the "missing subunits"
4766	case, because that won't cause the obsolete .ali files that cause
4767	confusion.
4768
47692017-09-08  Bob Duff  <duff@adacore.com>
4770
4771	* sinput-l.adb: Remove unused "with Unchecked_Conversion;". It's
4772	unclear why this didn't cause a warning.
4773	* a-uncdea.ads, a-unccon.ads: Add "Ada." to names in the
4774	pragmas. It's unclear why this didn't cause an error.
4775

4777
4778	* exp_spark.adb (Expand_SPARK_N_Object_Renaming_Declaration):

4782	the item does not have a proper entity.
4783	(Analyze_Input_Item): Add a guard in case the item does not have a
4784	proper entity.
4785	(Collect_States_And_Objects): Include object renamings in the
4786	items being collected.
4787	(Resolve_State): Update the documentation of this routine.
4788	* sem_util.adb (Entity_Of): Add circuitry to handle
4789	renamings of function results.
4790	(Remove_Entity): New routine.

47982017-09-08  Eric Botcazou  <ebotcazou@adacore.com>
4799
4800	* repinfo.adb (List_Record_Info): During first loop,
4801	do not override the normalized position and first bit
4802	if they have already been set.	Move fallback code
4803	for the packed case to the case where it belongs.
4804	* sem_ch13.adb (Adjust_Record_For_Reverse_Bit_Order):
4805	Also adjust the normalized position of components.
4806	(Adjust_Record_For_Reverse_Bit_Order_Ada_95): Likewise.
4807
48082017-09-08  Ed Schonberg  <schonberg@adacore.com>
4809
4810	* exp_disp.adb (Make_DT, Set_All_DT_Position): Handle properly
4811	the placement of a primitive operation O that renames an operation
4812	R declared in an inner package, and which is thus not a primitive
4813	of the dispatching type of O. In this case O is a new primitive
4814	and does not inherit its dispatch table position from R (which
4815	has none).
4816
48172017-09-08  Ed Schonberg  <schonberg@adacore.com>
4818
4819	* sem_dim.adb (Analyze_Dimension_If_Expression,
4820	Analyze_Dimension_Case_Expression): new subprograms to verify

4824	call Analyze_Dimension.
4825

48322017-09-08  Ed Schonberg  <schonberg@adacore.com>
4833
4834	* sem_ch12.adb (Check_Generic_Parent): New procedure within
4835	Analyze_Associations, to handle actual packages that depend on
4836	previous instances.  If a package IAP that is an instantiation is
4837	used as an actual in a subsequent instantiation SI in the same
4838	scope, and IAP has a body, IAP must be frozen before SI. If
4839	the generic parent of IAP is itself declared in a previous
4840	instantiation in the same scope, that instantiation must also
4841	be frozen before SI.
4842	(Install_Body): Prevent double insertion of freeze node for
4843	instance.
4844

4853	* sem_ch13.adb (Analyze_Aspect_Specifications, case
4854	Linker_Section): If the aspect applies to an object declaration

4857	initialization code.
4858
48592017-09-08  Ed Schonberg  <schonberg@adacore.com>
4860

4901
4902	* sem_ch6.adb (Analyze_Function_Return): Do not
4903	insert an explicit conversion to force the displacement of the

4906	as in "return raise ...".

4919	reference to Get_Unit_Instantiation_Node.
4920	* exp_dist.adb (Build_Package_Stubs): update reference to

49942017-09-07  Ed Schonberg  <schonberg@adacore.com>
4995
4996	* exp_disp.adb (Replace_Formals): If thr formal is classwide,

5059
5060	* einfo.ads, einfo.adb (Access_Disp_Table_Elab_Flag): New
5061	attribute. Defined for record types and subtypes.
5062	* exp_ch3.ads (Init_Secondary_Tags): Adding new formal
5063	(Init_Tags_List) to facilitate generating separate code in the
5064	IP routine to initialize the object components and for completing
5065	the elaboration of dispatch tables.
5066	* exp_ch3.adb (Build_Init_Procedure): Improve the code
5067	generated in the IP routines by means of keeping separate
5068	the initialization of the object components from the
5069	initialization of its dispatch tables.	(Init_Secondary_Tags):
5070	Adding new formal (Init_Tags_List) and adjusting calls to
5071	Ada.Tags.Set_Dynamic_Offset_To_Top since it has a new formal;
5072	adjusting also calls to Ada.Tags.Register_Interface_Offset
5073	because the type of one of its formals has been changed.
5074	* a-tags.ads, a-tags.adb (Register_Interface_Offset): Profile
5075	modified. Instead of receiving a pointer to an object this
5076	routine receives now a primary tag.
5077	(Set_Dyanic_Offset_To_Top): Profile modified. This routine receives an
5078	additional formal: the tag of the primary dispatch table.
5079	* exp_disp.ads (Elab_Flag_Needed): New subprogram.
5080	* exp_disp.adb (Elab_Flag_Needed): New subprogram.
5081	(Make_Tags): Adding the declaration of the elaboration flag (if needed).
5082	* exp_aggr.adb (Build_Record_Aggr_Code): Adding actual of new
5083	formal in calls to Init_Secondary_Tags.

5090	applied to generic subprograms.
5091
50922017-09-07  Arnaud Charlet  <charlet@adacore.com>
5093
5094	* sem_util.adb (Check_Part_Of_Reference): rename Conc_Typ to Conc_Obj
5095	(because it refers to the anonymous concurrent object, not its type);
5096	fix condition for emitting error message about task/protected type,
5097
50982017-09-07  Bob Duff  <duff@adacore.com>
5099
5100	* binde.adb (Debug_Flag_Old): If both -do and -dp
5101	are specified, behave as if just -do was specified, rather than
5102	using a mixture.
5103
51042017-09-07  Nicolas Roche  <roche@adacore.com>

5108
51092017-09-07  Arnaud Charlet  <charlet@adacore.com>
5110
5111	* sem_prag.adb (Find_Role): The Global_Seen flag
5112	is now consulted not only for abstract states and variables,
5113	but for all kinds of items.
5114	(Collect_Subprogram_Inputs_Outputs): Do not process formal
5115	generic parameters, because unlike ordinary formal parameters,
5116	generic formals only act as input/ outputs if they are explicitly
5117	mentioned in a Global contract.
5118

5134	derived recor type, copy the dikensions if any of each component
5135	of the parent record to the corresponding component declarations
5136	of the derived record. These expressions are used among other
5137	things as default values in aggregates with box associations.

5139	repinfo.adb, sem_attr.adb, sem_ch10.adb, sem_ch6.adb, sem_prag.adb:

5182	Make_Build_In_Place_Call_In_Anonymous_Context): Do not use the
5183	secondary stack for all functions that return limited tagged
5184	types -- just do it for dispatching calls.  Misc cleanup.
5185	* sem_util.ads, sem_util.adb (Unqual_Conv): New function to
5186	remove qualifications and type conversions. Fix various bugs
5187	where only a single level of qualification or conversion was
5188	removed, so e.g. "T1'(T2'(X))" would incorrectly return "T2'(X)"
5189	instead of "X".
5190	* checks.adb, exp_util.ads, exp_util.adb, sem_res.adb: Misc related
5191	cleanup.
5192
51932017-09-07  Ed Schonberg  <schonberg@adacore.com>
5194

5199	of body is a predicate function as well.
5200	(Resolve_Aspect_Expressions, Resolve_Name): For a component
5201	association, only the expression needs resolution, not the name.
5202	(Resolve_Aspect_Expressions, case Predicates): Construct and
5203	analyze the predicate function declaration in the scope of the
5204	type, before making the type and its discriminants visible.

5244
52452017-09-06  Bob Duff  <duff@adacore.com>
5246
5247	* binde.adb (Find_Elab_Order): Do not run Elab_Old unless
5248	requested. Previously, the -do switch meant "run Elab_New and
5249	Elab_Old and use the order chosen by Elab_Old, possibly with
5250	debugging printouts comparing the two orders."	Now it means
5251	"do not run Elab_New." This is of use if there are bugs that
5252	cause Elab_New to crash.
5253	(Elab_Position, Num_Chosen): Change type to Nat, to avoid various
5254	type conversions.
5255	* ali.ads (Elab_Position): Change type to Nat, to avoid various

5269	* freeze.adb (Freeze_Record_Type)
5270	<Sized_Component_Total_Round_RM_Size>: New local variable to
5271	accumulate the rounded RM_Size of components.  Update it for
5272	every component whose RM_Size is statically known.  Add missing
5273	guard to check that bit packing is really required before issuing
5274	the error about packing.  Swap condition for clarity's sake.
5275	* sem_prag.adb (Usage_Error): Fix reference to SPARK RM in comment.

5297
5298	* sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
5299	entity of a mutable type and the right-hand side is a conditional
5300	expression, resolve the alternatives of the conditional using
5301	the base type of the target entity, because the alternatives
5302	may have distinct subtypes. This is particularly relevant if

5304
53052017-09-06  Ed Schonberg  <schonberg@adacore.com>
5306
5307	* checks.adb (Apply_Predicate_Check): If the expression is an
5308	aggregate that is the RHS of an assignment, apply the check to
5309	the LHS after the assignment, rather than to the aggregate. This
5310	is more efficient than creating a temporary for the aggregate,
5311	and prevents back-end crashes when the aggregate includes a
5312	dynamic "others' association.
5313
53142017-09-06  Yannick Moy  <moy@adacore.com>

5331
53322017-09-06  Gary Dismukes  <dismukes@adacore.com>
5333
5334	* errout.adb (Error_Msg): Separate the
5335	treatment for warning vs. style messages in inlinings and
5336	instantiations. Prevents blowups on calls to Warn_Insertion for
5337	style messages, which should not be called in that case because

5368	been computed. Otherwise, Adjust_Instantiation_Sloc will ignore

5474
5475	* sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
5476	we include the proper header. Otherwise, we just declare the necessary
5477	things from the capabilities library. This is so we can build on
5478	machines without that library, while still enabling that library.
5479	At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
5480	simply return 0 if the library is not present, or not included
5481	in the link.

5508	suppress the ".all" suffix when displaying a dereference whose

5711	Move Ada.Command_Line.Response_File to System.Response_File,

5863
5864	* sem_util.adb (Needs_One_Formal): The first formal of such a

6343
6344	* sem_ch4.adb (Analyze_Call): In Ada2012 an incomplete type from a
6345	limited view may appear in the profile of a function, and a call to

6486	properly a reference to a formal of an enclosing subprogram. if

6528	* exp_ch3.adb (Freeze_Type): Do not generate an invariant
6529	procedure body for a local (sub)type declaration within a
6530	predicate function. Invariant checks do not apply to these, and
6531	the expansion of the procedure will happen in the wrong scope,

6572
6573	* exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
6574	Refine predicate for the case where the primitive operation
6575	is a renaming of equality.  An overriding operation that is
6576	a user-defined renaming of predefined equality inherits its
6577	slot from the overridden operation. Otherwise it is treated
6578	as a predefined op and occupies the same predefined slot as
6579	equality. A call to it is transformed into a call to its alias,
6580	which is the predefined equality. A dispatching call thus uses
6581	the proper slot if operation is further inherited and called
6582	with class-wide arguments.

6666	* checks.adb (Null_Exclusion_Static_Checks):
6667	Call Compile_Time_Constraint_Error instead of
6668	Apply_Compile_Time_Constraint_Error in the component case. Also
6669	call that when Array_Comp is True, with an appropriate warning for
6670	the array component case. Only create an explicit initialization
6671	by null in the case of an object of a null-excluding access type
6672	(and no longer do that in the component case).
6673	* sem_ch3.adb (Check_Component): Add a Boolean parameter
6674	Array_Comp defaulted to False.	Pass Empty for the Comp
6675	actual when calling Null_Exclusion_Static_Checks in the case
6676	where Comp_Decl matches Object_Decl, because we don't have a
6677	component in that case. In the case of an object or component
6678	of an array type, pass True for Array_Comp on the recursive call
6679	to Check_Component.

6683	* s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
6684	compute the linux priority from the Ada priority. Call this everywhere
6685	required. In particular, the previous version was not doing this
6686	computation when setting the ceiling priority in various places. It
6687	was just converting to C.int, which results in a ceiling that is off

6793
67942017-05-02  Bob Duff  <duff@adacore.com>
6795
6796	* exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
6797	to find primitive ops, instead of using an Identifier that will
6798	later be looked up. This is necessary because these ops are not
6799	necessarily visible at all places where we need to call them.
6800	* exp_util.ads: Minor comment fix.
6801
68022017-05-02  Ed Schonberg  <schonberg@adacore.com>
6803
6804	* sem_ch6.adb (Fully_Conformant_Expressions): Two entity
6805	references are fully conformant if they are both expansions
6806	of the discriminant of a protected type, within one of the
6807	protected operations. One occurrence may be expanded into a
6808	constant declaration while the other is an input parameter to
6809	the corresponding generated subprogram.
6810
68112017-05-02  Justin Squirek  <squirek@adacore.com>
6812
6813	* sem_ch3.adb (Check_For_Null_Excluding_Components): Created for
6814	recursivly searching composite-types for null-excluding access
6815	types and verifying them.
6816	(Analyze_Object_Declaration): Add a
6817	call to Check_Null_Excluding_Components for static verification
6818	of non-initialized objects.
6819	* checks.adb, checks.ads (Null_Exclusion_Static_Checks): Added
6820	a parameter for a composite-type's component and an extra case

6842
6843	* sem_ch8.adb (Premature_Usage): If the premature usage of
6844	an entity is as the expression in its own object decaration,
6845	rewrite the reference as Any_Id to prevent cascaded errors or
6846	compiler loops when such an entity is used in an address clause.
6847
68482017-05-01  Eric Botcazou  <ebotcazou@adacore.com>
6849

6865
6866	* exp_ch6.adb (Insert_Post_Call_Actions):
6867	Code clean up. Insert the post-call actions after an enclosing

6869	actual parameter in the procedure call.
6870
68712017-04-28  Eric Botcazou  <ebotcazou@adacore.com>
6872
6873	* freeze.adb (Check_Component_Storage_Order): If there is a clause
6874	for the component, also reject the attribute if the component
6875	doesn't end on a byte boundary and its scalar storage order is
6876	different from that of the enclosing record type.
6877

6911
6912	* sem_util.ads, sem_util.adb (Might_Raise): New function
6913	that replaces Is_Exception_Safe, but has the opposite
6914	sense. Is_Exception_Safe was missing various cases -- calls inside
6915	a pragma Debug, calls inside an 'if' or assignment statement,
6916	etc. Might_Raise now walks the entire subtree looking for things
6917	that can raise.
6918	* exp_ch9.adb (Is_Exception_Safe): Remove.
6919	(Build_Protected_Subprogram_Body): Replace call to
6920	Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
6921	constants where possible).
6922	* exp_ch7.adb: Rename Is_Protected_Body -->
6923	Is_Protected_Subp_Body. A protected_body is something different
6924	in the grammar.
6925
69262017-04-28  Eric Botcazou  <ebotcazou@adacore.com>
6927

6953	Interrupt_Handler and Attach_Handler): Generate reference
6954	to protected operation to prevent spurious warnings about

69582017-04-28  Ed Schonberg  <schonberg@adacore.com>
6959
6960	* sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
6961	that follows an expression function must not be relocated to
6962	the generated body, because it applies to the code that follows.
6963
69642017-04-28  Gary Dismukes  <dismukes@adacore.com>
6965
6966	* sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test

69912017-04-28  Ed Schonberg  <schonberg@adacore.com>
6992
6993	* sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
6994	node between access types, freeze the designated type as well,
6995	so that dispatch table pointers are created in the proper scope,
6996	and not in the constructed body of the expression function.
6997
69982017-04-28  Bob Duff  <duff@adacore.com>
6999
7000	* alloc.ads (Nodes_Initial): Go back to previous value. The large

7024
7025	* sem_res.adb (In_Instance_Code): New predicate in
7026	Valid_Conversion, to determine whether a type conversion appears
7027	as (or within) an actual for a formal object.  Type conversions
7028	in instances are not rechecked in Valid_Conversion because
7029	visibility changes between generic location andi instance may
7030	lead to spurious errors, but conversions within an actual must be
7031	fully checked, and they are not fully resolved when pre-analyzing
7032	the actuals.

7130
7131	* exp_util.adb (Replace_Entity): The prefix of a 'Result

7133	which the condition applies. If the condition is inherited
7134	by a type extension, the prefix becomes a reference to the

7149	Remove unused function.
7150	* alloc.ads (Nodes_Initial): Use a much larger value, because
7151	the compiler was spending a lot of time copying the nodes table
7152	when it grows. This number was chosen in 1996, so is rather out
7153	of date with current memory sizes. Anyway, it's virtual memory.
7154	Get rid of Orig_Nodes_...; use Node_... instead.

7206	that may apply to the body that is executed. (This is specified

72212017-04-27  Ed Schonberg  <schonberg@adacore.com>
7222
7223	* sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
7224	prefix can be an object reference in which case Obj'Image (X)
7225	can only be interpreted as an indexing of the parameterless
7226	version of the attribute.
7227	* par-ch4.adb (P_Name): An attribute reference can be the prefix of
7228	an indexing or a slice operation if the attribute does not require
7229	parameters. In Ada2012 'Image also belongs in this category,
7230	and A'Image (lo .. hi) is legal and must be parsed as a slice.

7574	Build body of subprogram that has a class-wide condition that
7575	contains calls to other primitives.
7576	(Build_Class_Wide_Clone_Call); Build a call to the common
7577	class-wide clone of a subprogram with classwide conditions. The
7578	body of the subprogram becomes a wrapper for a call to the
7579	clone. The inherited operation becomes a similar wrapper to which
7580	modified conditions apply, and the call to the clone includes
7581	the proper conversion in a call the parent operation.
7582	(Build_Class_Wide_Clone_Decl (Spec_Id : Entity_Id): For a
7583	subprogram that has a classwide condition that contains calls to
7584	other primitives, build an internal subprogram that is invoked
7585	through a type-specific wrapper for all inherited subprograms
7586	that may have a modified condition.
7587	* sem_prag.adb (Check_References): If subprogram has a classwide
7588	condition, create entity for corresponding clone, to be invoked
7589	through wrapper subprograns.

7591	message about placement if pragma isi internally generated.
7592	* sem_ch6.adb (Analyze_Subprogram_Body_Helper): If subprogram has
7593	a classwide clone, build body of clone as copy of original body,
7594	and rewrite original body as a wrapper as a wrapper for a call to
7595	the clone, so that it incorporates the original pre/postconditions
7596	of the subprogram.
7597	* freeze.adb (Check_Inherited_Conditions): For an inherited
7598	subprogram that inherits a classwide condition, build spec and
7599	body of corresponding wrapper so that call to inherited operation
7600	gets the modified conditions.
7601	* contracts.adb (Analyze_Contracts): If analysis of classwide
7602	condition has created a clone for a primitive operation, analyze
7603	declaration of clone.

7674	* sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Do not
7675	perform check if the current scope does not come from source,
7676	as is the case for a rewritten task body, because check has
7677	been performed already, and may not be doable because of changed
7678	visibility.

76862017-04-27  Ed Schonberg  <schonberg@adacore.com>
7687
7688	* sem_ch4.adb (Analyze_Call): If the return type of a function
7689	is incomplete in an context in which the full view is available,
7690	replace the type of the call by the full view, to prevent spurious
7691	type errors.
7692	* exp_disp.adb (Check_Premature_Freezing): Disable check on an
7693	abstract subprogram so that compiler does not reject a parameter
7694	of a primitive operation of a tagged type being frozen, when

7891	* exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
7892	to manage the secondary stack when an enclosing scope already
7893	performs this functionality (aka relaxed management). Switch
7894	-gnatd.s may be used to force strict management in which case

7900
7901	* sem_res.adb (Resolve_Call): Refine further the handling of
7902	limited views of return types in function calls. If the function
7903	that returns a limited view appears in the current unit,
7904	we do not replace its type by the non-limited view because
7905	this transformation is performed int the back-end. However,
7906	the type of the call itself must be the non-limited view, to

7914	(Class_Wide_Clone): New attribute of subprogram. Designates
7915	subprogram created for primitive operations with class-wide
7916	pre/postconditions that contain calls to other primitives. The
7917	clone holds the body of the original primitive, but the
7918	pre/postonditions do not apply to it. The original body is
7919	rewritten as a wrapper for a call to the clone.
7920	(Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
7921	the flag is set, no code for the corresponding pre/postconditions
7922	is inserted into its body.

8469
8470	* exp_attr.adb (Expand_Attribute_Reference, case 'Read):
8471	If the type is an unchecked_union, replace the attribute with
8472	a Raise_Program_Error (rather than inserting such before the
8473	attribute reference) to handle properly the case where we are
8474	processing a component of a larger record, and we need to prevent
8475	further expansion for the unchecked union.
8476	(Expand_Attribute_Reference, case 'Write): If the type is
8477	an unchecked_union, check whether enclosing scope is a Write
8478	subprogram. Replace attribute with a Raise_Program_Error if the
8479	discriminants of the unchecked_union type have not default values
8480	because such a use is erroneous..

8694	and save a copy of the expression in the pragma expression.
8695	(Build_Invariant_Procedure_Body): Default initalize vars,
8696	remove return condition on interfaces, always use the
8697	private type for interfaces, and move the processing of types
8698	until after the processing of invariants for the full view.
8699	(Build_Invariant_Procedure_Declaration): Remove condition
8700	to return if an interface type is encountered and add
8701	condition to convert the formal parameter to its class-wide
8702	counterpart if Work_Typ is abstract.

8704	(Replace_Type_Ref): Remove class-wide dispatching for the current
8705	instance of the type.
8706	(Replace_Type_References): Remove parameter "Derived"

8724	* sem_ch3.adb (Derive_Subprogram): Implement rule in RM 6.1.1
8725	(10-15): if derived type T with progenitors is abstract,
8726	and primitive P of this type inherits non-trivial classwide
8727	preconditions from both a parent operation and from an interface
8728	operation, then the inherited operation is abstract if the parent
8729	operation is not null.
8730	* sem_disp.ads, sem_disp.adb: replace function Covers_Some_Interface
8731	with Covered_Interface_Op to yield the actual interface operation
8732	that is implemented by a given inherited operation.
8733
87342017-04-25  Javier Miranda  <miranda@adacore.com>
8735
8736	* exp_ch4.adb (Expand_N_Op_Expon): Relocate left

8741
8742	* exp_attr.adb (Attribute_Unrestricted_Access):

8764	attribute types with the same designated type keep either of
8765	them and do not report an ambiguity.  A true ambiguity will be

8769
8770	* a-numeri.ads: Change the encoding of Greek letter Pi from
8771	brackets encoding to UTF-8.  Use pragma Wide_Character_Encoding
8772	to indicate the encoding. We considered using a byte order mark
8773	(BOM), but that causes various trouble (misc software eats the
8774	BOM, if you have a patch with a BOM, then it's not at the start
8775	of the patch, so it's not a BOM, the BOM affects with-ing files,
8776	etc.).

8820	both an ancestor and a progenitor (RM 6.1.1 (10-13).
8821	* sem_disp.adb (Check_Dispatching_Context): A call to an abstract
8822	subprogram need not be dispatching if it appears in a precondition
8823	for an abstract or null subprogram.

8948
8949	* bindgen.adb (Gen_Elab_Calls): Also update counter of lone
8950	specs without elaboration code that have an elaboration counter
8951	nevertheless, e.g.  when compiled with -fpreserve-control-flow.
8952	* sem_ch10.adb (Analyze_Compilation_Unit):
8953	Set_Elaboration_Entity_Required when requested to preserve
8954	control flow, to ensure the unit elaboration is materialized at
8955	bind time, resulting in the inclusion of the unit object file
8956	in the executable closure at link time.
8957
89582017-04-25  Pierre-Marie de Rodat  <derodat@adacore.com>
8959
8960	* exp_dbug.adb: In Debug_Renaming_Declaration,
8961	when dealing with indexed component, accept to produce a renaming
8962	symbol when the index is an IN parameter or when it is a name
8963	defined in an outer scope.
8964

89822017-04-25  Hristian Kirtchev  <kirtchev@adacore.com>
8983

8989	predicate to operate on type qualifications.
8990
89912017-04-25  Hristian Kirtchev  <kirtchev@adacore.com>
8992
8993	* sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
8994	Minor reformatting.
8995
89962017-04-25  Bob Duff  <duff@adacore.com>
8997
8998	* sem_prag.adb (No_Return): Give an error if the pragma applies
8999	to a body. Specialize the error for the specless body case,
9000	as is done for (e.g.) pragma Convention.
9001	* debug.adb: Add switch -gnatd.J to disable the above legality
9002	checks. This is mainly for use in our test suite, to avoid
9003	rewriting a lot of illegal (but working) code.	It might also
9004	be useful to customers. Under this switch, if a pragma No_Return
9005	applies to a body, and the procedure raises an exception (as it
9006	should), the pragma has no effect. If the procedure does return,
9007	execution is erroneous.
9008
90092017-04-25  Bob Duff  <duff@adacore.com>
9010
9011	* exp_ch6.adb (Expand_Actuals): This is the
9012	root of the problem. It took N as an 'in out' parameter, and in
9013	some cases, rewrote N, but then set N to Original_Node(N). So
9014	the node returned in N had no Parent. The caller continued
9015	processing of this orphaned node. In some cases that caused a
9016	crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
9017	and trips over the Empty Parent). The solution is to make N an
9018	'in' parameter.  Instead of rewriting it, return the list of
9019	post-call actions, so the caller can do the rewriting later,
9020	after N has been fully processed.
9021	(Expand_Call_Helper): Move most of Expand_Call here. It has
9022	too many premature 'return' statements, and we want to do the
9023	rewriting on return.
9024	(Insert_Post_Call_Actions): New procedure to insert the post-call
9025	actions in the appropriate place. In the problematic case,
9026	that involves rewriting N as an Expression_With_Actions.
9027	(Expand_Call): Call the new procedures Expand_Call_Helper and
9028	Insert_Post_Call_Actions.
9029
90302017-04-25  Ed Schonberg  <schonberg@adacore.com>
9031
9032	* sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
9033	properly type derived from generic formal types, to handle
9034	properly modified version of ACATS 4.1B B611017.
9035
90362017-04-25  Javier Miranda  <miranda@adacore.com>
9037
9038	* exp_unst.adb (Subp_Index): Adding missing
9039	support for renamings and functions that return a constrained
9040	array type (i.e. functions for which the frontend built a
9041	procedure with an extra out parameter).

9057	Assert. Current character can be ASCII.CR.
9058
90592017-04-25  Ed Schonberg  <schonberg@adacore.com>
9060
9061	* sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
9062	convention Stdcall, which has a number of exceptions. Convention
9063	is legal on a component declaration whose type is an anonymous
9064	access to subprogram.
9065
90662017-04-25  Hristian Kirtchev  <kirtchev@adacore.com>
9067

9070	with a subtype created for purposes of constraining a private
9071	type with discriminants.

9083	that its parent type has a private extension.
9084	* sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
9085	New subprogram.
9086	* usage.adb: Document -gnatw.j and -gnatw.J.

9091	reformatting.
9092
90932017-04-25  Bob Duff  <duff@adacore.com>
9094
9095	* binde.adb (Validate): Do not pass dynamic strings
9096	to pragma Assert, because older compilers do not support that.
9097
90982017-04-25  Bob Duff  <duff@adacore.com>
9099
9100	* s-fileio.adb (Close): When a temp file is
9101	closed, delete it and clean up its Temp_File_Record immediately,
9102	rather than waiting until later.
9103	(Temp_File_Record): Add File
9104	component, so Close can know which Temp_File_Record corresponds
9105	to the file being closed.
9106	(Delete): Don't delete temp files,
9107	because they are deleted by Close.
9108	(Open): Set the File component
9109	of Temp_File_Record. This requires moving the creation of the
9110	Temp_File_Record to the end, after the AFCB has been created.
9111
91122017-04-25  Hristian Kirtchev  <kirtchev@adacore.com>

9143	when converting from float to integer.	(Determine_Range): In
9144	GNATprove mode, take into account the possibility of conversion
9145	from float to integer.
9146	* sem_res.adb (Resolve_Type_Conversion): Only enforce range
9147	check on conversions from fixed-point to integer, not anymore

9157
91582017-04-25  Hristian Kirtchev  <kirtchev@adacore.com>
9159
9160	* checks.adb (Insert_Valid_Check): Partially reimplement validity
9161	checks.

9194
9195	* sem_ch8.adb (Use_One_Type): If a use_type_clause
9196	is redundant, set its Used_Operations to empty. This is only
9197	necessary for use clauses that appear in the parent of a generic
9198	child unit, because those use clauses get reanalyzed when we
9199	instantiate the generic, and we don't want the Used_Operations
9200	carried over from the original context (where it was probably
9201	not redundant).
9202

9214	the above bugs won't rear their ugly heads again.
9215
92162017-04-25  Ed Schonberg  <schonberg@adacore.com>
9217
9218	* sem_ch8.adb (Find_Type): For an attribute reference
9219	'Class, if prefix type is synchronized and previous errors
9220	have suppressed the creation of the corresponding record type,
9221	create a spurious class-wide for the synchonized type itself,
9222	to catch other misuses of the attribute
9223
92242017-04-25  Steve Baird  <baird@adacore.com>
9225
9226	* exp_ch6.adb (Expand_Simple_Function_Return): if CodePeer_Mode
9227	is True, then don't generate the accessibility check for the
9228	tag of a tagged result.
9229	* exp_intr.adb (Expand_Dispatching_Constructor_Call):
9230	if CodePeer_Mode is True, then don't generate the
9231	tag checks for the result of call to an instance of
9232	Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
9233	descendant of" check and the accessibility check).

9242
9243	* exp_ch4.adb (Library_Level_Target): New function.
9244	(Expand_Concatenate): When optimization is enabled, also expand
9245	the operation out-of-line if the concatenation is present within
9246	the expression of the declaration of a library-level object and
9247	not only if it is the expression of the declaration.
9248
92492017-04-25  Bob Duff  <duff@adacore.com>
9250
9251	* freeze.adb (Freeze_Object_Declaration): Do
9252	not Remove_Side_Effects if there is a pragma Linker_Section,
9253	because in that case we want static initialization in the

9261
9262	* sem_attr.adb (Statically_Denotes_Object): New predicate, to
9263	handle the proposed changes to rules concerning potentially
9264	unevaluated expressions, to include selected components that
9265	do not depend on discriminants, and indexed components with
9266	static indices.
9267	* sem_util.adb (Is_Potentially_Unevaluated): Add check for
9268	predicate in quantified expression, and fix bugs in the handling
9269	of case expressions and membership test.

9333
9334	* sem_ch4.adb (Analyze_Selected_Component): Additional refinement
9335	on analysis of prefix whose type is a current instance of a
9336	synchronized type, but where the prefix itself is an entity that

9338
93392017-04-25  Ed Schonberg  <schonberg@adacore.com>
9340
9341	* exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
9342	the identity of callable entities therein, because they have been
9343	properly resolved, and prefixed calls may have been rewritten

9348	* exp_ch3.adb (Build_Init_Statements): Convert

9365
9366	* urealp.adb (UR_Write): Reverse previous patch
9367	adding documentation on why we generate multiplications instead
9368	of divisions (needed to avoid expressions whose computation with

9372
9373	* erroutc.adb (Set_Specific_Warning_Off,
9374	Set_Warnings_Mode_Off): Use the correct source file for
9375	Stop. Was using Current_Source_File, which is only valid during

9381
9382	* lib.ads, lib.adb (In_Internal_Unit): New functions similar

9384	* sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace

9454	logic.
9455
94562017-04-25  Ed Schonberg  <schonberg@adacore.com>
9457
9458	* sem_ch4.adb (Analyze_Selected_Component): Refine analysis
9459	of prefix whose type is a current instance of a synchronized
9460	type. If the prefix is an object this is an external call (or
9461	requeue) that can only access public operations of the object. The
9462	previous predicate was too restrictive, and did not allow public
9463	protected operations, only task entries.
9464

9466

9476	* exp_ch7.adb (Allows_Finalization_Master): Do not generate a
9477	master for an access type subject to pragma No_Heap_Finalization.
9478	* exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
9479	allocated or deallocated does not finalization actions if the
9480	associated access type is subject to pragma No_Heap_Finalization.
9481	* opt.ads Add new global variable No_Heap_Finalization_Pragma.
9482	* par-prag.adb Pragma No_Heap_Finalization does not need special
9483	processing from the parser.
9484	* sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
9485	??? comments. Use the new predicate Is_Anonymous_Access_Type.

9492	* snames.ads-tmpl: Add new predefined name No_Heap_Finalization
9493	and corresponding pragma id.
9494
94952017-04-25  Bob Duff  <duff@adacore.com>
9496
9497	* freeze.adb (Freeze_Record_Type): Use the
9498	underlying type of the component type to determine whether it's
9499	elementary. For representation clause purposes, a private type
9500	should behave the same as its full type.
9501	* fname.ads, fname.adb (Is_Predefined_File_Name):
9502	Make sure things like "system.ali" are recognized as predefined.
9503
95042017-04-25  Javier Miranda  <miranda@adacore.com>
9505
9506	* debug.adb: Update documentation of -gnatd.6.

9509
9510	* sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
9511	element iterator when the name is an overloaded function call,
9512	one of whose interpretations yields an array.
9513
95142017-04-25  Bob Duff  <duff@adacore.com>
9515
9516	* uname.ads, uname.adb (Is_Predefined_Unit_Name,
9517	Is_Internal_Unit_Name): New functions for operating on unit
9518	names, as opposed to file names. There's some duplicated code
9519	with fname.adb, which is unfortunate, but it seems like we don't
9520	want to add dependencies here.
9521	* fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
9522	to Is_Predefined_Unit_Name; the former was wrong, because Uname
9523	is not a file name at all.
9524	* fname.ads, fname.adb: Document the fact that
9525	Is_Predefined_File_Name and Is_Internal_File_Name can be called
9526	for ALI files, and fix the code so it works properly for ALI
9527	files. E.g. these should return True for "system.ali".

9541	and integrated code from Add_Parent_Invariants and
9542	Add_Interface_Invariants.

9544	relavant code was inlined into both Add_Own_Invariant and
9545	Add_Inherited_Invariant.

9571	(Replace_Type_References):
9572	Append an extra parameter to allow for dispatching replacements
9573	and add the corrasponding logic.
9574	(Type_Invariant): Remove
9575	Replace_Typ_Refs and replace its references with calls to
9576	Replace_Type_References.

9585	* fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
9586	"gnat.adc" should not be considered a predefined file name.
9587	That required (or at least encouraged) a lot of cleanup of global
9588	variable usage. We shouldn't be communicating information via
9589	the global name buffer.
9590	* bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
9591	* restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

9652	to prevent the generation of subtypes (such as discriminated

9669	(Build_DIC_Procedure_Body): Add formal parameter
9670	For_Freeze. Add local variable Build_Body. Inherited DIC pragmas

9701	the error message when the attribute reference is an actual in
9702	a call to a subprogram inherited from a generic formal type with

10961
10962	* checks.adb (Apply_Type_Conversion_Checks): Disable small optimization

11012	selected component has a prefix that might be interpreted
11013	as a parameterless function call, but none of the candidate
11014	interpretations is parameterless, and there is a hidden homonym
11015	of the prefix that is a package.
11016	* sem_ch8.adb (Find_Selected_Component): If the prefix might be

11032	* lib-xref-spark_specific.adb (Traverse_Stub): routine refactored
11033	from repeated code of Traverse_Compilation_Unit.
11034	(Traverse_Declaration_Or_Statement): fixed detection of
11035	generic subprograms and packages; also, iteration over case
11036	statement alternatives rewritten to avoid testing if the first
11037	alternative is present (since it must be present due to Ada
11038	syntax restrictions).

11052	* sem_dim.adb (Analyze_Dimension): Analyze object declaration and
11053	identifier nodes that do not come from source, to handle properly
11054	dimensionality check within an inlined body which inclddes both
11055	original operands and rewritten operands. This removes spurious

11132	of an expression-function may have iterators and loops with

11176
11177	* binde.adb (Elab_New): New elaboration order algorithm
11178	that is expected to cause fewer ABE issues. This is a work in
11179	progress. The new algorithm is currently disabled, and can be
11180	enable by the -dp switch, or by modifying the Do_Old and Do_New
11181	etc. flags and rebuilding. Experimental code is included to
11182	compare the results of the old and new algorithms.
11183	* binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
11184	can have multiple of these tables, so the old and new algorithms
11185	can coexist.
11186	* bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
11187	parameter of type array. This avoids the global variable, and
11188	allows bounds checking (which is normally defeated by the tables
11189	packages). It also ensures that the Elab_Order is read-only
11190	to Bindgen.
11191	* bindgen.adb: Pass Elab_Order as an 'in' parameter to all
11192	subprograms that need it, as above.
11193	* debug.adb: Document new -dp switch. Modify doc of old -do
11194	switch.
11195	* gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
11196	and Bindgen.  Move writing of closure (-R and -Ra switches)
11197	to Binde; that's more convenient.

111992017-01-13  Ed Schonberg  <schonberg@adacore.com>

11201	* sem_ch6.adb (Analyze_Expression_Function): If the expression
11202	function is a completion, all entities referenced in the
11203	expression are frozen. As a consequence, a reference to an
11204	uncompleted private type from an enclosing scope is illegal.

11298	* sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
11299	mode a choice that is a subtype with a static predicate is

11320	* sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
11321	Loop_Actions and Box_Present are attributes of
11322	N_Iterated_Component_Association nodes. Box_Present is always
11323	False in this case.
11324	* sprint.adb (Sprint_Node): An Iterated_Component_Association
11325	has a Discrete_Choices list, as specified in the RM. A
11326	Component_Association for aggregate uses instead a Choices list.
11327	We have to live with this small inconsistency because the new
