269 * exp_util.adb (Expand_Subtype_From_Expr): Do not expand
270 expression if its type is derived from a limited type with
271 unknown discriminants, because the expansion (which is a call)

393 (Check_Dependency_Clause): Properly detect a match between two
394 'Result attributes. Update the various post-match cases to use
395 Is_Already_Matched as this routine now automatically recognizes

398 (Remove_Extra_Clauses): New routine.
399 (Report_Extra_Clauses): Remove the detection of ... => null

458 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
459 an object declaration for an array type with a modular index type
460 with the size of Long_Long_Integer. Special processing is needed
461 in this case to compute reliably the size of the object, and
462 eventually to raise Storage_Error, when wrap-around arithmetic
463 might compute a meangingless size for the object.
465 2017-01-23 Justin Squirek <squirek@adacore.com>

472 * sem_res.adb (Resolve_Call): In the part of the code where
473 it is deciding whether to turn the call into an indexed
474 component, avoid doing so if the call is to an instance of

476 indexed component, and resolution of that turns it back into a
477 function call, and so on, resulting in infinite recursion.
478 * sem_util.adb (Needs_One_Actual): If the first formal has a
479 default, then return False.

521 Ada.Real_Time.Clock_Time.
522 * sem_util.adb: Minor reformatting.
524 2017-01-20 Ed Schonberg <schonberg@adacore.com>
526 * sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
527 must be treated as delayed aspect even if the expression is
528 a literal, because the aspect affects the freezing and the
529 elaboration of the object to which it applies.

1073 2017-01-13 Ed Schonberg <schonberg@adacore.com>
1075 * einfo.ads: minor grammar fixes in comment of Normalized_Position_Max.
1076 * scil_ll.adb: Minor style fix in comment.
1077 * sem_ch8.adb (Analyze_Expanded_Name): Perform dimension analysis
1078 even if entity is already set, because the node may be renalyzed
1079 after inlining transformations.
1081 2017-01-13 Javier Miranda <miranda@adacore.com>
1083 * sem_res.adb (Resolve_Call): Do not establish a transient scope
1084 for a call to inlinable expression function (since the call will
1085 be replaced by its returned object).
1086 * exp_ch6.ads (Is_Inlinable_Expression_Function): New subprogram.
1087 * exp_ch6.adb (Expression_Of_Expression_Function): New subprogram.
1088 (Expand_Call): For inlinable expression function call replace the
1089 call by its returned object.

1101 located in the caller of this routine (to leave the code more clean).
1102 (Build_Contract_Only_Subprogram): Code cleanup.
1103 * scil_ll.ads, scil_ll.adb (Get_Contract_Only_Body_Name): Removed.
1104 (Get_Contract_Only_Missing_Body_Name): Removed.
1106 2017-01-13 Javier Miranda <miranda@adacore.com>
1108 * sem_ch6.adb (Cloned_Expression): New subprogram.
1109 (Freeze_Expr_Types): Complete previous patch since the expression
1110 of an expression-function may have iterators and loops with
1111 defining identifiers which, as part of the preanalysis of the
1112 expression, may be left decorated with itypes that will not be
1113 available in the tree passed to the backend.
1115 2017-01-13 Ed Schonberg <schonberg@adacore.com>
1117 * checks.adb (Apply_Type_Conversion_Checks): Optimize a type
1118 conversion to Integer of an expression that is an attribute
1119 reference 'Pos on an enumeration type.
1121 2017-01-13 Bob Duff <duff@adacore.com>
1123 * atree.ads: Minor comment fix.
1125 2017-01-13 Justin Squirek <squirek@adacore.com>
1127 * sem_ch6.adb (Check_Aggregate_Accessibility): Ignore function
1128 calls in accessibility check on return statement.
1130 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
1132 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
1133 Ensure that the input body is a subprogram body before trying to
1134 determine whether it denoted an expression function. Note that
1135 subprogram body stubs cannot denote expression functions.
1137 2017-01-13 Gary Dismukes <dismukes@adacore.com>
1139 * bindgen.adb, sem_ch6.adb, binde.adb, exp_ch3.adb: Minor reformatting
1142 2017-01-13 Javier Miranda <miranda@adacore.com>
1144 * einfo.ads (Component_Bit_Offset): Fix documentation.
1145 * sem_ch13.adb (Check_Record_Representation_Clause): Skip check
1146 on record holes for components with unknown compile-time offsets.

1151 * g-locfil.ads: Minor comment fix.
1153 2017-01-13 Bob Duff <duff@adacore.com>
1155 * binde.adb (Elab_New): New elaboration order algorithm
1156 that is expected to cause fewer ABE issues. This is a work in
1157 progress. The new algorithm is currently disabled, and can be
1158 enable by the -dp switch, or by modifying the Do_Old and Do_New
1159 etc. flags and rebuilding. Experimental code is included to
1160 compare the results of the old and new algorithms.
1161 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
1162 can have multiple of these tables, so the old and new algorithms
1164 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
1165 parameter of type array. This avoids the global variable, and
1166 allows bounds checking (which is normally defeated by the tables
1167 packages). It also ensures that the Elab_Order is read-only
1169 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
1170 subprograms that need it, as above.
1171 * debug.adb: Document new -dp switch. Modify doc of old -do
1173 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
1174 and Bindgen. Move writing of closure (-R and -Ra switches)
1175 to Binde; that's more convenient.
1177 2017-01-13 Ed Schonberg <schonberg@adacore.com>
1179 * sem_ch6.adb (Analyze_Expression_Function): If the expression
1180 function is a completion, all entities referenced in the
1181 expression are frozen. As a consequence, a reference to an
1182 uncompleted private type from an enclosing scope is illegal.
1184 2017-01-13 Javier Miranda <miranda@adacore.com>
1186 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
1187 (Analyze_Subprogram_Body_Helper): At the occurrence of an
1188 expression function declaration that is a completion, its
1189 expression causes freezing (AI12-0103).
1191 2017-01-13 Vadim Godunko <godunko@adacore.com>
1193 * a-coinho-shared.adb: Fix memory leaks in Constant_Reference and
1194 Reference functions of Ada.Containers.Indefinite_Holders.

1198 * s-os_lib.ads: Minor comment fixes.
1200 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
1202 * exp_ch3.adb (Default_Initialize_Object): Do not default
1203 initialize an object when it is of a task type and restriction
1204 No_Tasking is in effect because the initialization is obsolete.
1205 * exp_ch9.adb (Build_Master_Entity): Do not generate a master when
1206 restriction No_Tasking is in effect.
1207 (Build_Master_Renaming): Do not rename a master when restriction
1208 No_Tasking is in effect.
1210 2017-01-13 Ed Schonberg <schonberg@adacore.com>
1212 * sem_aggr.adb (Resolve_Array_Aggregate): The code that verifies
1213 the legality of An others clause applies as well to a choice in
1214 an Iterated_component_ association.
1215 (Resolve_Iterated_Component_Association): An others choice
1217 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An
1218 Iterated_Component_Association is not static.
1220 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
1222 * exp_ch3.adb (Freeze_Type): Mark the Ghost mode as set in case
1223 control is passed to the expresion handler before the new mode
1225 * sem_ch12.adb (Analyze_Package_Instantiation,
1226 Analyze_Subprogram_Instantiation): Mark the Ghost mode as set
1227 in case control is passed to the expresion handler before the
1230 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
1232 * sem_aggr.adb, sem_ch3.adb, inline.adb, sem_util.adb, exp_ch4.adb,

1237 * inline.adb: Minor reformatting and typo fix.
1239 2017-01-13 Ed Schonberg <schonberg@adacore.com>
1241 * sem_util.ads, sem_util.adb (Choice_List): Move function here
1242 from sem_aggr.adb, for use elsewhere.
1243 * sem_ch3.adb (Analyze_Object_Declaration): Use Choice_List.
1244 * sem_aggr.adb (Resolve_Array_Aggregate): Remove
1245 Iterated_Component_Present.
1246 * exp_aggr.adb: Use Choice_List throughout, to handle
1247 Iterated_Component_Associations.
1248 (Gen_Loop): Generate proper loop for an
1249 Iterated_Component_Association: loop variable has the identifier
1250 of the original association. Generate a loop even for a single
1251 component choice, in order to make loop parameter visible in
1253 (Flatten): An Iterated_Component_Association is not static.
1255 2017-01-13 Yannick Moy <moy@adacore.com>
1257 * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
1258 float exponentiation for statically known small negative values
1259 is the reciprocal of the exponentiation for the opposite value
1261 * s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):
1262 Ensure that the value of float exponentiation for negative values
1263 is the reciprocal of the exponentiation for the opposite value
1265 * inline.adb (Expand_Inlined_Call): Fix the count

1272 expression in delay statement as OK for volatile context.
1274 2017-01-13 Ed Schonberg <schonberg@adacore.com>
1276 * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
1277 mode a choice that is a subtype with a static predicate is
1278 replaced by the values it covers. This transformation must not
1279 be performed in ASIS mode, to preserve the source for analysis.
1281 2017-01-13 Justin Squirek <squirek@adacore.com>
1283 * nlists.ads: Correct minor typo.
1285 2017-01-13 Gary Dismukes <dismukes@adacore.com>

1292 Iterated_Component_Association is a named association in an
1294 * sem_aggr.adb (Resolve_Iterated_Component_Association): New
1295 procedure, subsidiary of Resolve_Array_Aggregate, to analyze
1296 and resolve the discrete choices and the expression of the
1298 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
1299 Loop_Actions and Box_Present are attributes of
1300 N_Iterated_Component_Association nodes. Box_Present is always
1302 * sprint.adb (Sprint_Node): An Iterated_Component_Association
1303 has a Discrete_Choices list, as specified in the RM. A
1304 Component_Association for aggregate uses instead a Choices list.
1305 We have to live with this small inconsistency because the new
1306 construct also has a defining identifier, and there is no way
1307 to merge the two node structures.
1309 2017-01-13 Yannick Moy <moy@adacore.com>
1311 * inline.adb (Remove_Aspects_And_Pragmas): Add Unused to the
1312 list of pragmas to remove. Remove pragmas from the list of
1313 statements in the body to inline.

1316 2017-01-13 Ed Schonberg <schonberg@adacore.com>
1318 * sem_ch3.adb (Resolve_Aspects): New procedure, subsidiary of
1319 Analyze_Declarations, to analyze and resolve the expressions of
1320 aspect specifications in the current declarative list, so that
1321 the expressions have proper entity and type info. This is needed
1322 for ASIS when there is no subsequent expansion to generate this
1323 semantic information.
1324 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
1325 original expression, to suppress cascaded errors when expression
1326 has been constant-folded.
1327 (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
1328 ASIS mode, because there is no subsequent expansion to decorate
1331 2017-01-13 Yannick Moy <moy@adacore.com>
1333 * inline.adb, inline.ads (Call_Can_Be_Inlined_In_GNATprove_Mode):
1334 New function to detect when a call may be inlined or not in
1336 (Expand_Inlined_Call): Ensure that a temporary
1337 is always created in the cases where a type conversion may be
1338 needed on an input parameter in GNATprove mode, so that GNATprove
1339 sees the check to perform.
1340 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
1341 when not applicable due to actual requiring type conversion
1342 with possible check but no temporary value can be copied for
1343 GNATprove to see the check.

1443 function, but the expression has been found legal as a static
1444 predicate during earlier analysis.
1445 * sem_eval.adb (Real_Or_String_Static_Predicate_Matches): Handle

1521 GNATprove_Mode here to Frontend.
1522 * frontend.adb (Frontend): Move the implicit with for System
