1107 a formal fixed point type is instantiated with a type that has
1108 a user-defined arithmetic operations, but the generic has no
1109 corresponding formal functions. This is worth a warning because
1110 of the special semantics of fixed-point operators.
1112 2016-07-06 Bob Duff <duff@adacore.com>
1114 * sem_attr.adb (Analyze_Attribute): Allow any expression of

1150 * sem_attr.adb (Analyze_Attribute_Old_Result): The attributes can
1151 appear in the postcondition of a subprogram renaming declaration,
1152 when the renamed entity is an attribute reference that is a
1153 function (such as 'Value).
1154 * sem_attr.adb (Eval_Attribute): It doesn't
1155 need to be static, just known at compile time, so use
1156 Compile_Time_Known_Value instead of Is_Static_Expression.
1157 This is an efficiency improvement over the previous bug fix.
1158 * sem_ch13.adb (Analyze_One_Aspect): Use Original_Node to detect
1159 illegal aspects on subprogram renaming declarations that may
1160 have been rewritten as bodies.

1170 that X'Enum_Rep, where X denotes a constant, can be constant
1171 folded. Fix it so it makes that assumption only when X denotes
1172 a STATIC constant.
1174 2016-07-04 Ed Schonberg <schonberg@adacore.com>
1176 * sem_ch4.adb (Compatible_Types_In_Predicate): New function

1192 2016-07-04 Bob Duff <duff@adacore.com>
1194 * sem_eval.adb (Decompose_Expr): Set 'out' parameters
1195 Kind and Cons to valid values, to avoid use of uninit vars.

1197 we're depending on BOTH Ent1 and Ent2 to be Present.
1198 * sem_aggr.adb (Resolve_Aggregate): Remove dead code.
1199 (Check_Misspelled_Component): Remove exit statement, because
1200 it's covered by the 'while' condition.
1201 * checks.adb (Apply_Selected_Range_Checks): Remove useless
1202 condition "or else not Checks_On".
1203 (Selected_Range_Checks):
1204 Initialize Known_LB and Known_HB to False, because they are
1205 tested unconditionally; avoid use of uninit vars.
1206 * frontend.adb (Frontend): Removed useless condition
1207 "Operating_Mode = Check_Semantics and then", and added an Assert
1208 to clarify why it was useless.
1209 * prep.adb (Preprocess): Remove redundant condition. Add an
1210 assertion.
1211 * sem_ch10.adb (Analyze_Proper_Body): Moved redundant condition
1212 "Original_Operating_Mode = Generate_Code" to an Assert.

1222 because it looks like it is used uninitialized otherwise.
1223 * sem_ch6.adb (Check_Return_Subtype_Indication): Moved redundant
1224 condition "not R_Type_Is_Anon_Access" to an Assert.
1225 * sem_elim.adb (Line_Num_Match): Moved redundant condition
1226 "Sloc_Trace (Idx) = '['" to an Assert.
1227 * sem_util.adb (Compile_Time_Constraint_Error): Change "J" to
1228 "J - 1". This code is trying to replace "?" with "<", but not if
1229 the "?" is quoted, as in "'?", so we want to check the PREVIOUS
1230 character for '''.
1231 * snames.adb-tmpl (Is_Pragma_Name): Remove useless condition
1232 "or else N = Name_Relative_Deadline". It's useless because
1233 Name_Relative_Deadline is in the range First_Pragma_Name
1234 .. Last_Pragma_Name.
1235 * treepr.adb (Visit_Node): Moved redundant condition "D =
1236 Union_Id (No_List)" to an Assert.

1251 2016-07-04 Ed Schonberg <schonberg@adacore.com>
1253 * sem_ch6.adb (Is_Non_Overriding_Operation): Add guard to test

1269 instantiating a child unit, do not install private declaration of
1270 a non-generic ancestor of the generic that is also an ancestor
1271 of the current unit: its private part will be installed when
1272 private part of ancestor itself is analyzed.
1274 2016-07-04 Ed Schonberg <schonberg@adacore.com>
1276 * sem_ch12.adb (Instantiate_Object): In SPARK mode add a guard
1277 to verify that the actual is an object reference before checking

1288 * sem_ch13.adb (New_Stream_Subprogram): If the attribute
1289 definition clause comes from an aspect specification, place the
1290 generated subprogram renaming in the freeze actions of the type.
1292 2016-07-04 Philippe Gil <gil@adacore.com>
1294 * g-debpoo.adb (Dump.Do_Report) - add space prefix to backtrace
1295 address dump - avoid new line sent directly to stdout.
1297 2016-07-04 Arnaud Charlet <charlet@adacore.com>
1299 * gnat1drv.adb, sem_ch12.adb, sem_elab.adb, sem_prag.adb, sem_res.adb:
1300 Relax elaboration checks in SPARK_Mode so that we rely on the
1301 static elaboration model (if used). We'll have a more precise
1302 check performed in flow analysis of gnat2why.
1304 2016-07-04 Ed Schonberg <schonberg@adacore.com>
1306 * ghost.adb (Prune_Node): A freeze node for an ignored ghost

1341 * sem_ch3.adb (Analyze_Object_Declaration): A declaration of a
1342 constant in a protected operation may be a homonym of a private
1343 component of the enclosing protected type. This declaration hides
1344 the component renaming constructed within the protected operation.
1346 2016-07-04 Bob Duff <duff@adacore.com>
1348 * xref_lib.adb (Parse_X_Filename, Parse_Identifier_Info): Ignore
1349 unknown files. Check that File_Nr is in the range of files we
1350 know about. The previous code was checking the lower bound,
1351 but not the upper bound.
1353 2016-07-04 Arnaud Charlet <charlet@adacore.com>
1355 * tracebak.c: Minor reformatting.
1357 2016-07-04 Yannick Moy <moy@adacore.com>

1387 * sem_ch4.adb (Resolve_One_Call): In the context of a predicate
1388 function the formal and the actual in a call may have different
1389 views of the same type, because of the delayed analysis of
1390 predicates aspects. Extend the patch that handles this potential
1391 discrepancy to handle private and full views as well.
1392 * sem_ch8.adb (Find_Selected_Component): Refine predicate that
1393 produces additional error when an illegal selected component
1394 looks like a prefixed call whose first formal is untagged.
1396 2016-07-04 Justin Squirek <squirek@adacore.com>
1398 * einfo.adb (Has_Pragma_Unused): Create this function as a setter
1399 for a new flag294 (Set_Has_Pragma_Unused): Create this procedure

1409 new pramga to Pragma_Id for pramga Unused.
1410 * sem_prag.adb (Analyze_Pragma): Create case for Pragma_Unused
1411 and move the block for Pragma_Unmodified and Pragma_Unreferenced
1412 out and into local subprograms.
1413 (Analyze_Unmodified, Analyze_Unreferenced): From the old pragma blocks
1414 that have been separated in to local subprograms add a parameter to
1415 indicate the if they are being called in the context of Pragma_Unused
1416 and handle it accordingly.
1417 (Is_Non_Significant_Pragma_Reference): Add an entry for Pragma_Unused
1418 and correct the position of Pragma_Unevaluated_Use_Of_Old.
1419 * sem_util.adb (Note_Possible_Modification): Recognize

1422 2016-07-04 Ed Schonberg <schonberg@adacore.com>
1424 * freeze.adb (Check_Inherited_Conditions): Perform two passes over
1425 the primitive operations of the type: one over source overridings
1426 to build the primitives mapping, and one over inherited operations
1427 to check for the need to create wrappers, and to check legality
1428 of inherited condition in SPARK.
1429 * sem_prag.ads (Update_Primitive_Mapping): Make public, for use
1430 in freeze actions.
1431 * sem_prag.adb (Build_Pragma_Check_Equivalent): Refine error

1458 support.
1460 2016-07-04 Ed Schonberg <schonberg@adacore.com>
1462 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case
1463 'Address): If the address comes from an aspect specification
1464 and not a source attribute definition clause, do not remove
1465 side effects from the expression, because the expression must
1466 be elaborated at the freeze point of the object and not at the

3005 * sem_res.adb (Resolve_Qualified_Expression): Generate a predicate
3006 check if type requires it.
3007 * checks.adb (Apply_Predicate_Check): Disable checks in the
3008 object declaration created for an expression with side-effects
3009 that requires a predicate check to prevent infinite recursion
3010 during expansion.

3052 have a subtype indication and the type is an unconstrained tagged
3053 type with defaulted discriminants, create an explicit constraint
3054 for it during analysis to prevent out-of-order freezing actions
3055 on generated classwide types.

3059 * exp_ch5.adb (Expand_N_Assignment_Statement):

3066 * sem_attr.adb (Analyze_Attribute, case 'Old): Do not use
3067 base type for attribute when type is discrete: transformation
3068 is not needed for such types, and leads to spurious errors if
3069 the context is a case construct.

3398 classwide type.
3400 2016-04-27 Hristian Kirtchev <kirtchev@adacore.com>
3402 * sem_util.ads, sem_util.adb (Output_Entity): New routine.

3417 * sem_prag.adb (Analyze_Pre_Post_Condition_In_Decl_Part):
3418 A generic subprogram is never a primitive operation, and thus
3419 a classwide condition for it is not legal.
3421 2016-04-27 Hristian Kirtchev <kirtchev@adacore.com>
3423 * sem_aggr.adb, sem_dim.adb, sem_dim.ads, einfo.adb: Minor

3440 2016-04-27 Ed Schonberg <schonberg@adacore.com>
3442 * sem_dim.ads, sem_dim.adb (Check_Expression_Dimensions): New
3443 procedure to compute the dimension vector of a scalar expression
3444 and compare it with the dimensions if its expected subtype. Used
3445 for the ultimate components of a multidimensional aggregate,
3446 whose components typically are themselves aggregates that are
3447 expanded separately. Previous to this patch, dimensionality
3448 checking on such aggregates generated spurious errors.
3449 * sem_aggr.adb (Resolve_Array_Aggregate): Use
3450 Check_Expression_Dimensions when needed.
3452 2016-04-27 Javier Miranda <miranda@adacore.com>

3475 2016-04-27 Ed Schonberg <schonberg@adacore.com>
3477 * exp_ch6.adb (Make_Build_In_Place_Call_In_Object_Declaration): If the
3478 return type is an untagged limited record with only access
3479 discriminants and no controlled components, the return value does not
3480 need to use the secondary stack.
3482 2016-04-27 Javier Miranda <miranda@adacore.com>
3484 * exp_util.adb (Remove_Side_Effects): When
3485 generating C code handle object declarations that have

3491 * a-textio.adb (Get_Line function): Handle properly the case of
3492 a line that has the same length as the buffer (or a multiple
3493 thereof) and there is no line terminator.
3494 * a-tigeli.adb (Get_Line procedure): Do not store an end_of_file
3495 in the string when there is no previous line terminator and we
3496 need at most one additional character.

3500 * s-rident.ads: Make No_Implicit_Loops non partition wide.
3502 2016-04-27 Arnaud Charlet <charlet@adacore.com>
3504 * sem_ch11.adb (Analyze_Handled_Statements): check useless
3505 assignments also in entries and task bodies, not only in
3506 procedures and declaration blocks.
3507 * sem_ch5.adb (Analyze_Block_Statement): check useless
3508 assignements in declaration blocks as part of processing their
3509 handled statement sequence, just like it was done for procedures
3510 and now is also done for entries and task bodies.
3511 * sem_warn.adb (Warn_On_Useless_Assignment): detect boundries
3512 of entries and task bodies just like of procedures.

3522 * exp_ch3.adb (Expand_N_Object_Declaration): Rewrite an object
3523 declaration of the form "X : T := Func (...);", where T is

3534 * freeze.adb (Copy_Import_Pragma): New routine.
3535 (Wrap_Imported_Subprogram): Copy the import pragma by first

3566 * sem_elab.adb (Check_Internal_Call): Do not
3567 consider a call when it appears within pragma Initial_Condition
3568 since the pragma is part of the elaboration statements of a
3569 package body and may only call external subprograms or subprograms
3570 whose body is already available.
3571 (Within_Initial_Condition): New routine.
3573 2016-04-27 Ed Schonberg <schonberg@adacore.com>

3929 appears within an instantiation, which can be nested at any level.
3930 * sem_ch12.adb (Analyze_Instance_And_Renamings): Do not copy Freeze
3931 node from anonymous subprogram to its visible renaming. The
3932 freeze node will be constructed if the subprogram carries
3933 delayed aspects.

3997 2016-04-21 Ed Schonberg <schonberg@adacore.com>
3999 * sem_ch8.adb (Find_Selected_Component): If prefix has an
4000 access type and designated type is a limited view, introduce
4001 an explicit dereference before continuing the analysis, and
4002 set its type to the non-limited view of the designated type,
4003 if we are in context where it is available.
4005 2016-04-21 Ed Schonberg <schonberg@adacore.com>

4024 * freeze.ads, freeze.adb (Freeze_Entity, Freeze_Before): Add
4025 boolean parameter to determine whether freezing an overloadable
4026 entity freezes its profile as well. This is required by
4027 AI05-019. The call to Freeze_Profile within Freeze_Entity is
4028 conditioned by the value of this flag, whose default is True.
4029 * sem_attr.adb (Resolve_Attribute, case 'Access): The attribute
4030 reference freezes the prefix, but it the prefix is a subprogram
4031 it does not freeze its profile.
4033 2016-04-21 Javier Miranda <miranda@adacore.com>
4035 * exp_util.adb (Build_Procedure_Form): No action needed for
4036 subprogram renamings since the backend can generate the call
4037 using the renamed subprogram. This leaves the tree more clean
4038 to the backend.

4053 Handle Extended_Return_Statements by replacing it with a block
4054 with assignments and a simple return statement.
4055 * exp_util.adb (Build_Procedure_Form): Make procedure entity
4056 invisible after analyzing declaration, to prevent improper
4057 overloading.

4061 * sem_ch6.adb (Build_Subprogram_Declaration): Propagate the
4062 attribute Rewritten_For_C to the body since since the expander
4063 may generate calls using that entity.

4142 C code.
4144 2016-04-20 Ed Schonberg <schonberg@adacore.com>
4146 * sem_ch13.adb (Build_Predicate_Function_Declaration): New
4147 function, to construct the declaration of a predicate function
4148 at the end of the current declarative part rather than at the
4149 (possibly later) freeze point of the type. This also allows uses
4150 of a type with predicates in instantiations elsewhere.
4151 (Resolve_Aspect_Expression): New procedure to detect visiblity
4152 errors in aspect expressions, at the end of the declarative part
4153 that includes the type declaration.

4155 predicate function from private to full view.
4156 * einfo.adb (Predicate_Function): Refine search for predicate

4189 * sem_ch6.adb (Enter_Overloaded_Entity): Do not warn about
4190 hiding unless we're actually hiding something. The previous
4191 code would (for example) warn about a "<" on a record type
4192 because it incorrectly thought it was hiding the "<" on Boolean
4193 in Standard. We need to check that the homonym S is in fact a
4194 homograph of a predefined operator.

4203 function that renames an instance of Unchecked_Conversion.
4204 * freeze.adb (Freeze_Subprogram): Generate the proper procedure
4205 declaration for a function returning an array.
4206 * exp_ch6.adb (Build_Procedure_Form): Moved to exp_util.

4210 * sem_util.ads, sem_util.adb (Is_Expanded_Priority_Attribute):
4211 New predicate to determine that in a context with full run-time,

4600 * exp_aggr.adb (Component_Count): Handle properly superflat
4601 arrays, i.e. empty arrays where Hi < Lo - 1, to ensure that the

4898 2016-04-18 Ed Schonberg <schonberg@adacore.com>
4900 * sem_ch6.adb (Check_Inline_Pragma): Use the Sloc of the
4901 body id as the sloc of the entity in the generated subprogram
4902 declaration, to avoid spurious conformance errors when style
4903 checks are enabled.
4905 2016-04-18 Ed Schonberg <schonberg@adacore.com>
4907 * sem_ch4.adb (Analyze_Selected_Component, Has_Dereference):
4908 Refine check on illegal calls to entities within a task body,
4909 when the entity is declared in an object of the same type. In
4910 a generic context there might be no explicit dereference but if
4911 the prefix includes an access type the construct is legal.
4913 2016-04-18 Arnaud Charlet <charlet@adacore.com>
4915 * rtsfind.ads, rtsfind.adb (RE_Id, RE_Unit_Table): add
4916 RE_Default_Priority.
4918 2016-04-18 Bob Duff <duff@adacore.com>
4920 * sem_prag.adb (Check_Arg_Is_Local_Name): Don't do the check
4921 if the pragma came from an aspect specification.
4923 2016-04-18 Gary Dismukes <dismukes@adacore.com>
4925 * gnat1drv.adb, contracts.adb: Minor reformatting and wording fixes.
4927 2016-04-18 Ed Schonberg <schonberg@adacore.com>
4929 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): To suppress
4930 superfluous conformance check on an inlined body with a previous
4931 spec, use the fact that the generated declaration does not come
4932 from source. We must treat the entity as coming from source to
4933 enable some back-end inlining when pragma appears after the body.
4935 2016-04-18 Gary Dismukes <dismukes@adacore.com>
4937 * lib-xref-spark_specific.adb, par-ch2.adb, errout.ads,
4938 exp_intr.adb: Minor reformatting and typo corrections.
4940 2016-04-18 Ed Schonberg <schonberg@adacore.com>
4942 * sem_ch6.adb: Code cleanup.
4944 2016-04-18 Thomas Quinot <quinot@adacore.com>
4946 * sem_ch13.adb: Minor reformatting and error message tweaking
4947 (remove extraneous spaces).
4949 2016-04-18 Johannes Kanig <kanig@adacore.com>
4951 * gnat1drv.adb (Gnat1drv): Force loading of System unit for SPARK.
4953 2016-04-18 Bob Duff <duff@adacore.com>
4955 * s-fileio.adb (Fopen_Mode): If Mode = Out_File, and the file
4956 exists, and it's a fifo, we use "w" as the open string instead of
4957 "r+". This is necessary to make a write to the fifo block until
4958 a reader is ready.
4960 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
4962 * sem_attr.adb (Denote_Same_Function): Account
4963 for a special case where a primitive of a tagged type inherits
4964 a class-wide postcondition from a parent type.
4966 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
4968 * par-ch2.adb (P_Expression_Or_Reserved_Word): New routine.
4969 (P_Pragma): Signal Scan_Pragma_Argument_Association when the use
4970 of reserved words is OK.
4971 (Scan_Pragma_Argument_Association):
4972 Add new formal Reserved_Words_OK and update the comment on
4973 usage. Code cleanup. Parse an expression or a reserved word in
4974 identifier form for pragmas Restriction_Warnings and Restrictions
4975 No_Use_Of_Attribute.
4976 * restrict.adb (Check_Restriction_No_Use_Of_Attribute):
4977 Reimplemented. (Check_Restriction_No_Use_Of_Pragma): Code cleanup.
4978 (Set_Restriction_No_Specification_Of_Aspect): Properly set the warning
4979 flag for an aspect.
4980 (Set_Restriction_No_Use_Of_Attribute): Properly set the warning
4981 flag for an attribute. (Set_Restriction_No_Use_Of_Entity):
4982 Update the parameter profile.
4983 (Set_Restriction_No_Use_Of_Pragma): Properly set the warning flag for
4984 a pragma.
4985 * restrict.ads (Check_Restriction_No_Use_Of_Attribute): Update
4986 the comment on usage.
4987 (Set_Restriction_No_Use_Of_Entity): Update the parameter profile.
4988 * sem_attr.adb (Analyze_Attribute): Check restriction
4989 No_Use_Of_Attribute.
4990 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Check
4991 restriction No_Use_Of_Attribute before any rewritings have
4992 taken place.
4993 * sem_prag.adb (Analyze_Pragma): Check restriction
4994 No_Use_Of_Pragma before any rewritings have taken place.
4996 2016-04-18 Bob Duff <duff@adacore.com>
4998 * sem_ch6.adb (Is_Inline_Pragma): The pragma
4999 argument can be a selected component, which has no Chars field,
5000 so we need to deal with that case (use the Selector_Name).
5001 (Check_Inline_Pragma): We need to test Is_List_Member before
5002 calling In_Same_List, because in case of a library unit, they're
5003 not in lists, so In_Same_List fails an assertion.
5005 2016-04-18 Bob Duff <duff@adacore.com>
5007 * namet.ads, namet.adb: Add an Append that appends a
5008 Bounded_String onto a Bounded_String. Probably a little more
5009 efficient than "Append(X, +Y);". Also minor cleanup.
5010 (Append_Decoded, Append_Decoded_With_Brackets, Append_Unqualified,
5011 Append_Unqualified_Decoded): Make sure these work with non-empty
5012 buffers.
5013 * casing.ads, casing.adb (Set_Casing): Pass a Bounded_String
5014 parameter, defaulting to Global_Name_Buffer.
5015 * errout.ads, errout.adb (Adjust_Name_Case): Pass a
5016 Bounded_String parameter, no default.
5017 * exp_ch11.adb (Expand_N_Raise_Statement): Use local
5018 Bounded_String instead of Global_Name_Buffer.
5019 * exp_intr.ads, exp_intr.adb (Write_Entity_Name): Rename it
5020 to Append_Entity_Name, and pass a Bounded_String parameter,
5021 instead of using globals.
5022 (Add_Source_Info): Pass a Bounded_String parameter, instead of
5023 using globals.
5024 (Expand_Source_Info): Use local instead of globals.
5025 * stringt.ads, stringt.adb (Append): Add an Append procedure
5026 for appending a String_Id onto a Bounded_String.
5027 (String_To_Name_Buffer, Add_String_To_Name_Buffer): Rewrite in
5028 terms of Append.
5029 * sem_prag.adb (Set_Error_Msg_To_Profile_Name): Adjust for new
5030 Adjust_Name_Case parameter.
5031 * erroutc.adb, uname.adb: Don't pass D => Mixed_Case to
5032 Set_Casing; that's the default.
5033 * lib-xref-spark_specific.adb (Add_SPARK_Scope): Pretend that calls to
5034 protected subprograms are entry calls; otherwise it is not possible to
5035 distinguish them from regular subprogram calls.
5037 2016-04-18 Gary Dismukes <dismukes@adacore.com>
5039 * sem_ch13.adb (Has_Good_Profile): Improvement
5040 of error message. Now indicates subtype_mark of formal parameter
5041 rather than the formal's name, plus minor rewording.
5043 2016-04-18 Pascal Obry <obry@adacore.com>
5045 * adaint.c, adaint.h, s-os_lib.ads: Add new routine Current_Process_Id.
5047 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
5049 * stringt.adb, exp_ch6.adb, sem_ch13.adb: Minor reformatting.
5051 2016-04-18 Gary Dismukes <dismukes@adacore.com>
5053 * par-ch4.adb, sem_prag.adb: Minor reformatting.
5055 2016-04-18 Bob Duff <duff@adacore.com>
5057 * sinput.ads, sinput.adb (Build_Location_String): Take a
5058 parameter instead of using a global variable. The function
5059 version no longer destroys the Name_Buffer.
5060 * stringt.ads, stringt.adb (String_From_Name_Buffer): Take a
5061 parameter, which defaults to the Global_Name_Buffer, so some
5062 calls can avoid the global.
5063 * exp_ch11.adb, exp_intr.adb: Use new interfaces above
5064 to avoid using globals. All but one call to Build_Location_String
5065 avoids the global. Only one call to String_From_Name_Buffer
5066 avoids it.
5068 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
5070 * namet.adb, namet.ads, exp_unst.adb: Minor reformatting.
5072 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
5074 * sem_eval.adb (Choice_Matches): Check the expression
5075 against the predicate values when the choice denotes a
5076 subtype with a static predicate.
5077 (Eval_Membership_Op): Code cleanup. Remove the suspicious guard which
5078 tests for predicates.
5079 (Is_OK_Static_Subtype): A subtype with a dynamic predicate
5080 is not static. (Is_Static_Subtype): A subtype with a dynamic
5081 predicate is not static.
5082 * sem_eval.ads (Is_OK_Static_Subtype): Update the comment on usage.
5083 (Is_Static_Subtype): Update the comment on usage.
5085 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
5087 * sem_prag.adb (Analyze_Input_Item): Allow
5088 generic formals to appear as initialization items.
5090 2016-04-18 Ed Schonberg <schonberg@adacore.com>
5092 * sem_ch13.adb (Analyze_Stream_TSS_Definition,
5093 Has_Good_Profile): Additional error message to indicate that
5094 the second parameter of the subprogram must be a first subtype.
5096 2016-04-18 Ed Schonberg <schonberg@adacore.com>
5098 * sem_ch6.adb (Analyze_Subprogram_Body_Helper, Is_Inline_Pragma):
5099 Use the pragma lookahead that determines whether a subprogram
5100 is to be inlined, when some level of backend optimization is
5101 required.
5102 * sem_ch12.ads, sem_ch12.adb (Add_Pending_Instantiation): Factorize
5103 code used to create an instance body when needed for inlining.
5104 * exp_ch6.adb (Expand_Call): When a call is to be inlined, and the
5105 call appears within an instantiation that is not a compilation
5106 unit, add a pending instantiation for the enclosing instance,
5107 so the backend can inline in turn the calls contained in the
5108 inlined body.
5110 2016-04-18 Ed Schonberg <schonberg@adacore.com>
5112 * sem_prag.adb (Build_Pragma_Check_Equivalent): The mapping
5113 that relates operations of the parent type to the operations of
5114 the derived type has three distinct sources:
5115 a) explicit operations of the derived type carry an
5116 Overridden_Operation that designates the operation in the
5117 ancestor.
5118 b) Implicit operations that are inherited by the derived type
5119 carry an alias that may be an explicit subprogram (in which case
5120 it may have an Overridden_ Operation indicator) or may also be
5121 inherited and carry its own alias.
5122 c) If the parent type is an interface, the operation of the
5123 derived type does not override, but the interface operation
5124 indicates the operation that implements it.
5125 * sem_prag.adb: Minor reformatting.
5126 * sem_prag.adb (Check_External_Property): Update
5127 the comment on usage. Reimplement.
5129 2016-04-18 Ed Schonberg <schonberg@adacore.com>
5131 * exp_ch5.adb (Expand_Assignment_Statement): In restricted
5132 profiles such as ZFP, ceiling priority is not available.
5134 2016-04-18 Bob Duff <duff@adacore.com>
5136 * namet-sp.ads: Minor typo fix, ironically in 'Spelling_Checker'.
5138 2016-04-18 Bob Duff <duff@adacore.com>
5140 * sem_elab.adb (Output_Calls): Use
5141 Get_Name_String, to clearly indicate that the global Name_Buffer
5142 is being used. The previous code used Is_Internal_Name, which
5143 returns a Boolean, but also has a side effect of setting the
5144 Name_Buffer. Then it called the other Is_Internal_Name, which uses
5145 the Name_Buffer for its input. And then it called Error_Msg_N,
5146 again using the Name_Buffer. We haven't eliminated the global
5147 usage here, but we've made it a bit clearer.
5148 This also allows us to have a side-effect-free version of
5149 Is_Internal_Name.
5150 * namet.ads, namet.adb: Provide a type Bounded_String, along with
5151 routines that can be used without using global variables. Provide
5152 Global_Name_Buffer so existing code can continue to use the
5153 global. Mark the routines that use globals as obsolete. New code
5154 shouldn't call the obsolete ones, and we should clean up existing
5155 code from time to time.
5156 Name_Find_Str is renamed as Name_Find.
5157 * namet.h: Changed as necessary to interface to the new version
5158 of Namet.
5159 * bindgen.adb, exp_unst.adb: Name_Find_Str is renamed as
5160 Name_Find.
5162 2016-04-18 Yannick Moy <moy@adacore.com>
5164 * sem_util.adb, sem_util.ads (Has_Full_Default_Initialization): used
5165 outside of GNATprove, hence it should not be removed.
5167 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
5169 * sem_prag.adb (Analyze_Refinement_Clause):
5170 The refinement of an external abstract state can now mention
5171 non-external constituents.
5172 (Check_External_Property): Update all SPARK RM references.
5174 2016-04-18 Bob Duff <duff@adacore.com>
5176 * exp_intr.adb: Remove some duplicated code.
5178 2016-04-18 Yannick Moy <moy@adacore.com>
5180 * a-nudira.adb, a-nudira.ads, a-nuflra.adb, a-nuflra.ads: Mark
5181 package spec and body out of SPARK.
5183 2016-04-18 Johannes Kanig <kanig@adacore.com>
5185 * spark_xrefs.ads: Minor comment update.
5187 2016-04-18 Johannes Kanig <kanig@adacore.com>
5189 * gnat1drv.adb (Gnat1drv): Force loading of System
5190 unit for SPARK.
5192 2016-04-18 Bob Duff <duff@adacore.com>
5194 * a-cuprqu.adb: Correction to previous change. If a new node
5195 is inserted at the front of the queue (because it is higher
5196 priority than the previous front node), we need to update
5197 Header.Next_Unequal -- not just in the case where the queue was
5198 previously empty.
5200 2016-04-18 Bob Duff <duff@adacore.com>
5202 * a-cuprqu.ads: Change the representation of List_Type from a
5203 singly-linked list to a doubly-linked list. In addition, add a
5204 pointer Next_Unequal, which points past a possibly-long chain
5205 of equal-priority items. This increases efficiency, especially
5206 in the case of many equal-priority items.
5207 * a-cuprqu.adb (Dequeue, Enqueue): Rewrite algorithms to take
5208 advantage of new data structure.
5209 (Finalize): Rewrite in terms of Dequeue, for simplicity.
5211 2016-04-18 Yannick Moy <moy@adacore.com>
5213 * contracts.adb (Analyze_Object_Contract,
5214 Analyze_Protected_Contract): Remove tests performed in GNATprove.
5215 * sem_util.adb, sem_util.ads (Has_Full_Default_Initialization):
5216 Remove query for tests performed in GNATprove.
5218 2016-04-18 Ed Schonberg <schonberg@adacore.com>
5220 * sem_aggr.adb (Resolve_Record_Aggregate): If
5221 Warn_On_Redundant_Constructs is enabled, report a redundant box
5222 association that does not cover any components, as it done for
5223 redundant others associations in case statements.
5225 2016-04-18 Ed Schonberg <schonberg@adacore.com>
5227 * sem_prag.adb (Collect_Inherited_Class_Wide_Conditions):
5228 Analyze the generated Check pragma for an inherited condition so
5229 that it does not freeze the dispatching type of the primitive
5230 operation, because it is pre-analyzed at the point of the
5231 subprogram declaration (and not in the subprogram body, as is
5232 done during regular expansion).
5234 2016-04-18 Vincent Celier <celier@adacore.com>
5236 * ali.ads: Increase the range of all _Id types to 100 millions.
5238 2016-04-18 Gary Dismukes <dismukes@adacore.com>
5240 * sem_warn.adb (Check_References): Change warning to suggest
5241 using pragma Export rather than saying "volatile has no effect".
5243 2016-04-18 Bob Duff <duff@adacore.com>
5245 * g-souinf.ads (Compilation_ISO_Date): New function to return
5246 the current date in ISO form.
5247 * exp_intr.adb (Expand_Source_Info, Add_Source_Info): Expand
5248 a call to Compilation_ISO_Date into a string literal containing
5249 the current date in ISO form.
5250 * exp_intr.ads (Add_Source_Info): Improve documentation.
5251 * sem_intr.adb (Check_Intrinsic_Subprogram): Recognize
5252 Compilation_ISO_Date.
5253 * snames.ads-tmpl (Name_Compilation_ISO_Date): New Name_Id.
5255 2016-04-18 Eric Botcazou <ebotcazou@adacore.com>
5257 * layout.adb (Set_Elem_Alignment): Extend setting of alignment
5258 to subtypes that are not first subtypes.
5260 2016-04-18 Ed Schonberg <schonberg@adacore.com>
5262 * sem_prag.ads (Collect_Inherited_Class_Wide_Conditions):
5263 Simplify interface.
5264 * sem_prag.adb (Collect_Inherited_Class_Wide_Conditions): Insert
5265 generated pragmas after subprogram declaration, rather than in
5266 the corresponding subprogram body.
5267 * sem_ch6.adb (New_Overloaded_Entity): In GNATProve
5268 mode, if the operation is overridding, call
5269 Collect_Inherited_Class_Wide_Conditions to generate the
5270 corresponding pragmas immediately after the corresponding
5271 subprogram declaration.
5273 2016-04-18 Arnaud Charlet <charlet@adacore.com>
5275 * spark_xrefs.ads (Xref_Index, Scope_Index, File_Index): restrict
5276 type to natural numbers.
5277 (Stype): document code characters for concurrent entities.
5279 2016-04-18 Olivier Hainque <hainque@adacore.com>
5281 * targparm.ads: Update the Frontend_Exceptions default internal
5282 value.
5283 (Frontend_Exceptions_On_Target): Change default value to True.
5285 2016-04-18 Ed Schonberg <schonberg@adacore.com>
5287 * sem_ch4.adb (Analyze_Selected_Component): Refine error
5288 detection when a selected component in the body of a synchronized
5289 type is a reference to an object of the same type declared
5290 elsewhere. The construct is legal if the prefix of the selected
5291 component includes an explicit dereference at any point.
5293 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
5295 * sem_ch3.adb (Analyze_Object_Declaration): Do not consider
5296 internally generated expressions when trying to determine whether
5297 a formal parameter of a tagged type subject to Extensions_Visible
5298 False is used to initialize an object.
5299 * sem_ch4.adb (Analyze_Type_Conversion): Do not consider
5300 internally generated expressions when trying to determine whether
5301 a formal parameter of a tagged type subject to Extensions_Visible
5302 False is used in a type conversion.
5304 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
5306 * sem_res.adb (Is_Protected_Operation_Call):
5307 Add guards to account for a non-decorated selected component.
5309 2016-04-18 Yannick Moy <moy@adacore.com>
5311 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Improve
5312 implementation of Body_Has_SPARK_Mode_On.
5313 * sem_prag.adb, sem_prag.ads (Get_SPARK_Mode_From_Annotation):
5314 New function replacing previous Get_SPARK_Mode_From_Pragma, that
5315 deals also with aspects.
5316 (Get_SPARK_Mode_Type): Make function internal again.
5317 * inline.adb, sem_ch7.adb, sem_util.adb: Use new
5318 Get_SPARK_Mode_From_Annotation.
5320 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
5322 * contracts.adb (Analyze_Object_Contract): Update references to
5323 SPARK RM.
5324 * freeze.adb (Freeze_Entity): Update references to SPARK RM.
5325 * ghost.adb Add with and use clauses for Sem_Disp.
5326 (Check_Ghost_Derivation): Removed.
5327 (Check_Ghost_Overriding):
5328 Reimplemented. (Check_Ghost_Policy): Update references to SPARK RM.
5329 (Check_Ghost_Primitive): New routine.
5330 (Check_Ghost_Refinement): New routine. (Is_OK_Ghost_Context):
5331 Update references to SPARK RM. (Is_OK_Pragma): Update references
5332 to SPARK RM. Predicates are now a valid context for references
5333 to Ghost entities.
5334 * ghost.ads (Check_Ghost_Derivation): Removed.
5335 (Check_Ghost_Overriding): Update the comment on usage.
5336 (Check_Ghost_Primitive): New routine.
5337 (Check_Ghost_Refinement): New routine.
5338 (Remove_Ignored_Ghost_Code): Update references to SPARK RM.
5339 * sem_ch3.adb (Process_Full_View): Remove the now obsolete check
5340 related to Ghost derivations
5341 * sem_ch6.adb (Check_Conformance): Remove now obsolete check
5342 related to the convention-like behavior of pragma Ghost.
5343 (Check_For_Primitive_Subprogram): Verify that the Ghost policy
5344 of a tagged type and its primitive agree.
5345 * sem_prag.adb (Analyze_Pragma): Update references to SPARK
5346 RM. Move the verification of pragma Assertion_Policy Ghost
5347 to the proper place. Remove the now obsolete check related
5348 to Ghost derivations.
5349 (Collect_Constituent): Add a call to Check_Ghost_Refinement.
5350 * sem_res.adb (Resolve_Actuals): Update references to SPARK RM.
5352 2016-04-18 Eric Botcazou <ebotcazou@adacore.com>
5354 * layout.adb: Fix more minor typos in comments.
5356 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
5358 * a-calend.ads, sem_prag.adb, sem_ch6.adb: Minor reformatting.
5360 2016-04-18 Ed Schonberg <schonberg@adacore.com>
5362 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): In GNATprove
5363 mode, collect inherited class-wide conditions to generate the
5364 corresponding pragmas.
5365 * sem_prag.ads (Build_Pragma_Check_Equivalent): Moved from contracts
5366 * contracts.adb (Collect_Inherited_Class_Wide_Conditions): New
5367 procedure for overriding subprograms, used to generate the pragmas
5368 corresponding to an inherited class- wide pre- or postcondition.
5369 * sem_prag.adb (Build_Pragma_Check_Equivalent): moved here
5370 from contracts.adb (Replace_Condition_Entities): Subsidiary
5371 Build_Pragma_Check_Equivalent, to implement the proper semantics
5372 of inherited class-wide conditions, as given in AI12-0113.
5373 (Process_Class_Wide_Condition): Removed.
5374 (Collect_Inherited_Class_Wide_Conditions): Iterate over pragmas
5375 in contract of subprogram, to collect inherited class-wide
5376 conditions.
5377 (Build_Pragma_Check_Equivalent): Moved to sem_prag.adb
5379 2016-04-18 Yannick Moy <moy@adacore.com>
