 400         * s-htable.adb: Fix typo.
 401
 402 2017-09-08  Bob Duff  <duff@adacore.com>
 403
 404         * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.

 415         Print something helpful in case N is invalid.

 417
 418 2017-09-08  Eric Botcazou  <ebotcazou@adacore.com>
 419

 422
 423 2017-09-08  Bob Duff  <duff@adacore.com>
 424
 425         * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
 426         Ada_2020, along the same lines as the other Ada version pragmas.
 427
 428 2017-09-08  Gary Dismukes  <dismukes@adacore.com>

 432 2017-09-08  Yannick Moy  <moy@adacore.com>
 433
 434         * sem_aggr.adb (Resolve_Record_Aggregate):
 435         Rewrite bounds of aggregate subexpressions which may depend on
 436         discriminants of the enclosing aggregate.
 437
 438 2017-09-08  Yannick Moy  <moy@adacore.com>
 439
 440         * sem_ch5.adb: Prevent assertion failure on illegal code.

 445         calling Renamed_Entity on an entity which cannot be a renaming.
 446
 447 2017-09-08  Eric Botcazou  <ebotcazou@adacore.com>
 448
 449         * exp_aggr.adb: Add with & use clause for Urealp.
 450         (Aggr_Assignment_OK_For_Backend): Accept (almost all)
 451         elementary types instead of just discrete types.
 452         * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
 453         * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
 454         Be prepared for the FP zero value in the memset case.  Add small
 455         guard.
 456
 457 2017-09-08  Eric Botcazou  <ebotcazou@adacore.com>
 458
 459         * s-htable.adb (Static_HTable.Reset): Use aggregate instead
 460         of loop.
 461
 462 2017-09-08  Hristian Kirtchev  <kirtchev@adacore.com>
 463
 464         * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
 465         of New_Copy because the latter leaves the syntactic structure of
 466         the tree inconsistent (a child is accessible through two parents)
 467         and prevents proper replication of itypes by subsequent calls
 468         to New_Copy_Tree.
 469         * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
 470         New_Copy because the latter leaves the syntactic structure of the
 471         tree inconsistent (a child is accessible through two parents)
 472         and prevents proper replication of itypes by subsequent calls
 473         to New_Copy_Tree.
 474         * sem_util.adb (In_Subtree): New routine.
 475         (New_Copy_Tree): Reimplemented.
 476         * sem_util.ads (In_Subtree): New routine.
 477         (New_Copy_Tree): Reimplemented.
 478
 479 2017-09-08  Ed Schonberg  <schonberg@adacore.com>
 480
 481         * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
 482         for aspect Default_Value is a static scalar value, but it does
 483         not freeze the type. Yhis allows for subsequent representation
 484         clauses for the type.
 485
 486 2017-09-08  Javier Miranda  <miranda@adacore.com>
 487
 488         * sem_ch8.adb (Find_Direct_Name.Undefined): Do
 489         not add entries into the undefined reference table when we are
 490         compiling with errors ignored.
 491
 492 2017-09-08  Ed Schonberg  <schonberg@adacore.com>
 493
 494         * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
 495         check if the instance is within an enclosing instance body. The
 496         formal package was legal in the enclosing generic, and is
 497         legal in the enclosing instantiation.  This optimisation may be
 498         applicable elsewhere, and it also removes spurious errors that
 499         may arise with on-the-fly processing  of instantiations that
 500         contain Inline_Always subprograms.
 501
 502 2017-09-08  Vincent Celier  <celier@adacore.com>
 503
 504         * gnatcmd.adb: Disregard empty argument of GNAT driver.

 507
 508         * checks.adb (Insert_Valid_Check): Manually decorate
 509         the generated temporary for range valdity checks.

 511 2017-09-08  Eric Botcazou  <ebotcazou@adacore.com>
 512
 513         * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
 514
 515 2017-09-08  Justin Squirek  <squirek@adacore.com>
 516
 517         * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
 518         case to handle underscore flags.
 519         * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
 520         new procedure to handle underscores.
 521
 522 2017-09-08  Javier Miranda  <miranda@adacore.com>
 523
 524         * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
 525         divisions with fixed point results to avoid generating twice
 526         the runtime check on divide by zero.
 527         * checks.adb (Apply_Divide_Checks): Ensure that operands are
 528         not evaluated twice (once for their runtime checks and once for
 529         their regular computation).
 530
 531 2017-09-08  Yannick Moy  <moy@adacore.com>
 532
 533         * sem_prag.adb (Analyze_Part_Of): Add missing
 534         return statements after issuing errors.  Add detection of
 535         out-of-order item and single concurrent type.

 664         * exp_ch6.adb (Expand_Call_JHelper): Add accessibility checks

 666         expression that includes a formal of the enclosing subprogram,
 667         In such cases, the accessibility level of the actual is that of

 680         and empty strings. Empty strings cause trouble because they can
 681         have super-null ranges (e.g. 100..10), which causes Ext_Copy to
 682         be empty, which causes an array index out of bounds.

1069
1070         * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
1071         sem_prag.adb to make it available for GNATprove; for concurrent
1072         types replace custom scope climbing with Scope_Same_Or_Within; for
1073         single concurrent objects add scope climbing (with Scope_Within),
1074         which was not there (that's the primary semantic change of this
1075         commit); also, when comparing a single concurrent object with
1076         its corresponding concurrent type rely on equality of types,
1077         not of objects (because that's simpler to code).
1078         * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
1079         (Analyze_Global_Item): adjust special-casing of references to the
1080         current instance of a concurrent unit in the Global contracts
1081         of task types and single tasks objects; similar for references
1082         in the protected operations and entries of protected types and
1083         single protected objects (in all these cases the current instance
1084         behaves as an implicit parameter and must not be mentioned in
1085         the Global contract).

1097         own body and appears as the prefix of a reference to an entity
1098         local to the child unit.

1162         the subunit case. It's still OK to set it in the "missing subunits"
1163         case, because that won't cause the obsolete .ali files that cause

1198         do not override the normalized position and first bit
1199         if they have already been set.  Move fallback code
1200         for the packed case to the case where it belongs.

1208         the placement of a primitive operation O that renames an operation
1209         R declared in an inner package, and which is thus not a primitive
1210         of the dispatching type of O. In this case O is a new primitive
1211         and does not inherit its dispatch table position from R (which
1212         has none).

1232         Analyze_Associations, to handle actual packages that depend on
1233         previous instances.  If a package IAP that is an instantiation is
1234         used as an actual in a subsequent instantiation SI in the same
1235         scope, and IAP has a body, IAP must be frozen before SI. If
1236         the generic parent of IAP is itself declared in a previous
1237         instantiation in the same scope, that instantiation must also
1238         be frozen before SI.

1458         attribute. Defined for record types and subtypes.
1459         * exp_ch3.ads (Init_Secondary_Tags): Adding new formal
1460         (Init_Tags_List) to facilitate generating separate code in the
1461         IP routine to initialize the object components and for completing
1462         the elaboration of dispatch tables.
1463         * exp_ch3.adb (Build_Init_Procedure): Improve the code
1464         generated in the IP routines by means of keeping separate
1465         the initialization of the object components from the
1466         initialization of its dispatch tables.  (Init_Secondary_Tags):
1467         Adding new formal (Init_Tags_List) and adjusting calls to
1468         Ada.Tags.Set_Dynamic_Offset_To_Top since it has a new formal;
1469         adjusting also calls to Ada.Tags.Register_Interface_Offset
1470         because the type of one of its formals has been changed.
1471         * a-tags.ads, a-tags.adb (Register_Interface_Offset): Profile
1472         modified. Instead of receiving a pointer to an object this
1473         routine receives now a primary tag.
1474         (Set_Dyanic_Offset_To_Top): Profile modified. This routine receives an
1475         additional formal: the tag of the primary dispatch table.

1509         is now consulted not only for abstract states and variables,
1510         but for all kinds of items.
1511         (Collect_Subprogram_Inputs_Outputs): Do not process formal
1512         generic parameters, because unlike ordinary formal parameters,
1513         generic formals only act as input/ outputs if they are explicitly
1514         mentioned in a Global contract.

1532         of the parent record to the corresponding component declarations
1533         of the derived record. These expressions are used among other

1580         secondary stack for all functions that return limited tagged
1581         types -- just do it for dispatching calls.  Misc cleanup.
1582         * sem_util.ads, sem_util.adb (Unqual_Conv): New function to
1583         remove qualifications and type conversions. Fix various bugs
1584         where only a single level of qualification or conversion was
1585         removed, so e.g. "T1'(T2'(X))" would incorrectly return "T2'(X)"
1586         instead of "X".
1587         * checks.adb, exp_util.ads, exp_util.adb, sem_res.adb: Misc related

1594         functions.
1595         * sem_ch13.adb (Build_Predicate_Functions): Indicate that entity
1596         of body is a predicate function as well.
1597         (Resolve_Aspect_Expressions, Resolve_Name): For a component
1598         association, only the expression needs resolution, not the name.

1643
1644         * binde.adb (Find_Elab_Order): Do not run Elab_Old unless
1645         requested. Previously, the -do switch meant "run Elab_New and
1646         Elab_Old and use the order chosen by Elab_Old, possibly with
1647         debugging printouts comparing the two orders."  Now it means
1648         "do not run Elab_New." This is of use if there are bugs that
1649         cause Elab_New to crash.
1650         (Elab_Position, Num_Chosen): Change type to Nat, to avoid various
1651         type conversions.

1669         every component whose RM_Size is statically known.  Add missing
1670         guard to check that bit packing is really required before issuing

1696         entity of a mutable type and the right-hand side is a conditional
1697         expression, resolve the alternatives of the conditional using
1698         the base type of the target entity, because the alternatives
1699         may have distinct subtypes. This is particularly relevant if
1700         the alternatives are aggregates.

1705         aggregate that is the RHS of an assignment, apply the check to
1706         the LHS after the assignment, rather than to the aggregate. This
1707         is more efficient than creating a temporary for the aggregate,
1708         and prevents back-end crashes when the aggregate includes a
1709         dynamic "others' association.

1762         * sem_ch12.adb (Copy_Generic_Node): When we copy a node
1763         that is a proper body corresponding to a stub, we defer the
1764         adjustment of the sloc until after the correct adjustment has
1765         been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
1766         the adjustment, because it will be outside the range in (the old,
1767         incorrect) S_Adjustment.
1768         * inline.adb: Use named notation for readability and uniformity.

1781         case when Op is of kind N_Qualified_Expression. In this case,
1782         the function is called recursively on the subexpression like in
1783         other cases.
1784         * make.adb: Minor reformatting

1871
1872         * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
1873         we include the proper header. Otherwise, we just declare the necessary
1874         things from the capabilities library. This is so we can build on
1875         machines without that library, while still enabling that library.
1876         At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
1877         simply return 0 if the library is not present, or not included
1878         in the link.
1879

1901         * pprint.ads (Expression_Image) Add new generic formal flag
1902         Hide_Temp_Derefs.  The flag defaults to False; CodePeer will

1904         * pprint.adb (Expression_Image) If the new flag is set, then
1905         suppress the ".all" suffix when displaying a dereference whose
1906         prefix is a use of a value-capturing compiler temp of the sort

2110         System.Response_File. This is to avoid having gnatbind depend
2111         Ada.Command_Line, which would damage the bootstrap process now
2112         that Ada.Command_Line contains modern Ada (the raise expression).
2113         * gnatbind.adb: Avoid dependence on
2114         Ada.Command_Line. Depend on System.Response_File instead
2115         of Ada.Command_Line.Response_File. Change one call to
2116         Ada.Command_Line.Command_Name to use Fill_Arg.  Change one call
2117         to Ada.Command_Line.Argument_Count to use Arg_Count.
2118         * gcc-interface/Make-lang.in, Makefile.rtl: Take note of the new files.

2121
2122         * frontend.adb (Frontend): Skip -gnatec=gnat.adc

2126
2127         * exp_ch5.adb (Get_Default_Iterator): Replace
2128         "Assert(False)" with "return Iter", because if an iterable

2186         rule in 6.5.1 (7/2): if a renaming is a completion of a subprogram

2209         node for a generic unit, even if it includes delayed aspect

2253         of the right-hand side has stored constraint, use its values
2254         (except for those that are renamings of parent discriminants)
2255         to produce additional assignments for the discriminants of the
2256         left-hand side, which are invisible in the righ-hand side and

2281         * sem_ch12.adb (Analyze_Subprogram_Instantiation): Propagate
2282         No_Return flag to instance if pragma applies to generic unit. This
2283         must be done explicitly because the pragma does not appear

2297         derived type with a mixture of renamed and constrained parent
2298         discriminants, the constraint for the target must obtain the
2299         discriminant values from both the operand and from the stored
2300         constraint for it, given that the constrained discriminants are
2301         not visible in the object.
2302         * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
2303         side may be derived from that of the left-hand side (as in the
2304         case of an assignment with a change of representation) so the
2305         discriminant to be used in the retrieval of the value of the
2306         component must be the entity in the type of the right-hand side.

2337         replace the entity of the alternative as well as the type,

2976         equality. A call to it is transformed into a call to its alias,
2977         which is the predefined equality. A dispatching call thus uses

3131
3132         * snames.ads-tmpl
3133         (Name_Assume, Name_Attribute_Definition, Name_Loop_Optimize,
3134         Name_No_Tagged_Streams): Move to regular pragmas.  Add
3135         placeholders for Default_Scalar_Storage_Order, Dispatching_Domain,
3136         and Secondary_Stack_Size.
3137         (Pragma_Id): Move Pragma_Assume,
3138         Pragma_Attribute_Definition, Pragma_Loop_Optimize and
3139         Pragma_No_Tagged_Streams to second part.

3148         detection for illegal references to private components or
3149         operations of a protected type in the body of the type.
3150
3151 2017-05-02  Eric Botcazou  <ebotcazou@adacore.com>
3152
3153         * opt.ads: Add missing GNAT markers in comments.
3154         * opt.adb (Set_Opt_Config_Switches): Do not override earlier

3156
3157 2017-05-02  Hristian Kirtchev  <kirtchev@adacore.com>
3158
3159         * checks.adb (Apply_Constraint_Check): Do not apply
3160         a discriminant check when the associated type is a constrained
3161         subtype created for an unconstrained nominal type.
3162         * exp_attr.adb: Minor reformatting.
3163
3164 2017-05-02  Bob Duff  <duff@adacore.com>
3165
3166         * sem_ch3.adb (OK_For_Limited_Init_In_05): Handle correctly
3167         the N_Raise_Expression case.
3168         * sem_ch6.adb (Check_Limited_Return): Minor: clarify comment,
3169         and add assertions.
3170
3171 2017-05-02  Yannick Moy  <moy@adacore.com>
3172
3173         * exp_ch4.adb (Expand_N_Op_Ne): Do not bump parenthese level and
3174         optimize length comparison in GNATprove mode.
3175         * exp_spark.adb (Expand_SPARK_Op_Ne): New function to rewrite
3176         operator /= into negation of operator = when needed.
3177         (Expand_SPARK): Call new
3178         function to expand operator /=.
3179
3180 2017-05-02  Ed Schonberg  <schonberg@adacore.com>
3181
3182         * exp_fixd.adb (Expand_Divide_Fixed_By_Fixed_Giving_Fixed):
3183         Simplify the expression for a fixed-fixed division to remove
3184         divisions by constants whenever possible, as an optimization
3185         for restricted targets.
3186
3187 2017-05-02  Hristian Kirtchev  <kirtchev@adacore.com>
3188
3189         * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
3190
3191 2017-05-02  Bob Duff  <duff@adacore.com>
3192
3193         * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
3194         to find primitive ops, instead of using an Identifier that will
3195         later be looked up. This is necessary because these ops are not
3196         necessarily visible at all places where we need to call them.
3197         * exp_util.ads: Minor comment fix.
3198
3199 2017-05-02  Ed Schonberg  <schonberg@adacore.com>
3200
3201         * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
3202         references are fully conformant if they are both expansions
3203         of the discriminant of a protected type, within one of the
3204         protected operations. One occurrence may be expanded into a
3205         constant declaration while the other is an input parameter to
3206         the corresponding generated subprogram.
3207
3208 2017-05-02  Justin Squirek  <squirek@adacore.com>
3209
3210         * sem_ch3.adb (Check_For_Null_Excluding_Components): Created for
3211         recursivly searching composite-types for null-excluding access
3212         types and verifying them.
3213         (Analyze_Object_Declaration): Add a
3214         call to Check_Null_Excluding_Components for static verification
3215         of non-initialized objects.
3216         * checks.adb, checks.ads (Null_Exclusion_Static_Checks): Added
3217         a parameter for a composite-type's component and an extra case
3218         for printing component information.
3219
3220 2017-05-02  Yannick Moy  <moy@adacore.com>
3221
3222         * sem_ch10.adb (Analyze_Subunit): Take
3223         configuration pragma into account when restoring appropriate
3224         pragma for analysis of subunit.
3225
3226 2017-05-02  Justin Squirek  <squirek@adacore.com>
3227
3228         * s-tasren.adb, s-tasini.adb, s-taprop-linux.adb,
3229         s-mudido-affinity.adb,, a-exetim-posix.adb, a-direio.adb,
3230         g-socket.adb, s-taenca.adb, s-fileio.adb: Remove unused use-type
3231         clauses from the runtime.
3232
3233 2017-05-02  Eric Botcazou  <ebotcazou@adacore.com>
3234
3235         * freeze.adb (Check_Component_Storage_Order): Do not treat bit-packed
3236         array components specially.
3237
3238 2017-05-02  Ed Schonberg  <schonberg@adacore.com>
3239
3240         * sem_ch8.adb (Premature_Usage): If the premature usage of
3241         an entity is as the expression in its own object decaration,
3242         rewrite the reference as Any_Id to prevent cascaded errors or
3243         compiler loops when such an entity is used in an address clause.
3244
3245 2017-05-01  Eric Botcazou  <ebotcazou@adacore.com>
3246
3247         * gcc-interface/decl.c (components_to_record): Add missing guard.
3248
3249 2017-05-01  Eric Botcazou  <ebotcazou@adacore.com>
3250
3251         * gcc-interface/decl.c (components_to_record): Add more comments.
3252         Put back pending fields onto the regular list if the misalignment
3253         happens to cancel itself.
3254
3255 2017-04-28  Ed Schonberg  <schonberg@adacore.com>
3256
3257         * sem_ch4.adb (Complete_Object_Operation): When rewriting the
3258         controlling actual in a prefixed call, preserve the original node
3259         information if the prefix itself has been rewritten, for ASIS use.
3260
3261 2017-04-28  Hristian Kirtchev  <kirtchev@adacore.com>
3262
3263         * exp_ch6.adb (Insert_Post_Call_Actions):
3264         Code clean up. Insert the post-call actions after an enclosing
3265         procedure call when N denotes a function call and appears as an
3266         actual parameter in the procedure call.
3267
3268 2017-04-28  Eric Botcazou  <ebotcazou@adacore.com>
3269
3270         * freeze.adb (Check_Component_Storage_Order): If there is a clause
3271         for the component, also reject the attribute if the component
3272         doesn't end on a byte boundary and its scalar storage order is
3273         different from that of the enclosing record type.
3274
3275 2017-04-28  Javier Miranda  <miranda@adacore.com>
3276
3277         * atree.ads (Info_Messages): Removed.
3278         (Warning_Info_Messages): New counter.
3279         (Report_Info_Messages): New counter.
3280         * err_vars.ads Update documentation.
3281         * errout.adb (Delete_Warning_And_Continuations): Update
3282         Info_Message occurrences.
3283         (Error_Msg_Internal): Update Info_Message occurrences.
3284         (Delete_Warning): Update Info_Message occurrences.
3285         (Write_Error_Summary): Update Info_Message occurrences.

3289         * errutil.adb (Error_Msg): Update Info_Message occurrences.
3290         (Finalize): Update Info_Message occurrences.
3291         (Initialize): Update Info_Message occurrences.
3292         * erroutc.adb (Delete_Msg): Update Info_Message occurrences.
3293         (Compilation_Errors): Update Info_Message_Occurences.
3294
3295 2017-04-28  Eric Botcazou  <ebotcazou@adacore.com>
3296
3297         * exp_ch3.adb (Build_Init_Statements): Likewise on Nam.
3298         * freeze.adb (Check_Component_Storage_Order): And on Comp_Byte_Aligned.
3299         * sem_aggr.adb (Resolve_Record_Aggregate): Initialize Box_Node.
3300         * sem_attr.adb (Loop_Entry): Initialize Encl_Loop.
3301         * sem_ch12.adb (Build_Operator_Wrapper): Add pragma Warnings on Expr.
3302         * sem_ch13.adb (Validate_Address_Clauses): Initialize Y_Alignment and
3303         Y_Size.
3304         * sem_eval.adb (Why_Not_Static): Initialize Typ.
3305         * sem_prag.adb (Analyze_Pragma): Add pragma Warnings on Str.
3306
3307 2017-04-28  Bob Duff  <duff@adacore.com>
3308
3309         * sem_util.ads, sem_util.adb (Might_Raise): New function
3310         that replaces Is_Exception_Safe, but has the opposite
3311         sense. Is_Exception_Safe was missing various cases -- calls inside
3312         a pragma Debug, calls inside an 'if' or assignment statement,
3313         etc. Might_Raise now walks the entire subtree looking for things
3314         that can raise.
3315         * exp_ch9.adb (Is_Exception_Safe): Remove.
3316         (Build_Protected_Subprogram_Body): Replace call to
3317         Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
3318         constants where possible).
3319         * exp_ch7.adb: Rename Is_Protected_Body -->
3320         Is_Protected_Subp_Body. A protected_body is something different
3321         in the grammar.
3322
3323 2017-04-28  Eric Botcazou  <ebotcazou@adacore.com>
3324
3325         * inline.adb (Expand_Inlined_Call): Initialize Targ1 variable.
3326         * par-ch3.adb (P_Component_Items): Initialize Decl_Node variable.
3327         (P_Discrete_Choice_List): Initialize Expr_Node variable.
3328         * par-ch9.adb (P_Task): Initialize Aspect_Sloc variable.
3329         (P_Protected): Likewise.
3330         * sem_case.adb (Check_Duplicates):
3331         Add pragma Warnings on variable.
3332         * sem_ch12.adb (Preanalyze_Actuals): Initialize Vis variable.
3333         * sem_ch4.adb (List_Operand_Interps):  Add pragma Warnings on variable.

3335         (Analyze_Exit_Statement): Initialize Scope_Id variable.
3336         (Analyze_Iterator_Specification): Initialize Bas variable.
3337         * sem_ch9.adb (Allows_Lock_Free_Implementation): Initialize
3338         Error_Count (Satisfies_Lock_Free_Requirements): Likewise.
3339         (Analyze_Accept_Statement): Initialize Task_Nam.
3340
3341 2017-04-28  Hristian Kirtchev  <kirtchev@adacore.com>
3342
3343         * checks.adb (Install_Primitive_Elaboration_Check):
3344         Do not generate an elaboration check if all checks have been
3345         suppressed.
3346
3347 2017-04-28  Ed Schonberg  <schonberg@adacore.com>
3348
3349         * sem_ch13.adb (Analyze_Aspect_Specifications, case
3350         Interrupt_Handler and Attach_Handler): Generate reference
3351         to protected operation to prevent spurious warnings about
3352         unreferenced entities. Previous scheme failed with style checks
3353         enabled.
3354
3355 2017-04-28  Ed Schonberg  <schonberg@adacore.com>
3356
3357         * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
3358         that follows an expression function must not be relocated to
3359         the generated body, because it applies to the code that follows.
3360
3361 2017-04-28  Gary Dismukes  <dismukes@adacore.com>
3362
3363         * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
3364         Relaxed_RM_Semantics to avoid having CodePeer issue errors on
3365         code that might violate the more stringent checking for 'Access
3366         introduced in Ada 2005.
3367
3368 2017-04-28  Arnaud Charlet  <charlet@adacore.com>
3369
3370         * a-cforse.adb: minor style fix in comment.
3371
3372 2017-04-28  Eric Botcazou  <ebotcazou@adacore.com>
3373
3374         * exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also
3375         initialize Block_Decls variable.
3376         (Expand_Entry_Barrier): Add pragma Warnings on Func_Body variable.
3377         (Build_Dispatching_Requeue): Add pragma Warnings on Op variable.
3378         * exp_disp.adb (Expand_Interface_Actuals): Initialize
3379         Formal_DDT and Actual_DDT variables.
3380         (Expand_Interface_Thunk): Initialize Iface_Formal.
3381         (Make_DT): Initialize Size_Comp.
3382         (Make_Select_Specific_Data_Table): Initialize Decls.
3383         * exp_dist.adb (Add_RACW_Primitive_Declarations_And_Bodies):
3384         Also initialize more RPC_Receiver_* variables.
3385         (Build_To_Any_Function): Initialize Cstr_Formal.
3386         * exp_prag.adb (Expand_Pragma_Contract_Cases): Initialize Msg_Str.
3387
3388 2017-04-28  Ed Schonberg  <schonberg@adacore.com>
3389
3390         * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
3391         node between access types, freeze the designated type as well,
3392         so that dispatch table pointers are created in the proper scope,
3393         and not in the constructed body of the expression function.
3394
3395 2017-04-28  Bob Duff  <duff@adacore.com>
3396
3397         * alloc.ads (Nodes_Initial): Go back to previous value. The large
3398         value makes large compilations faster, but small compilations slower.
3399
3400 2017-04-28  Arnaud Charlet  <charlet@adacore.com>
3401
3402         * sem_util.adb: minor typos in Is_Child_Or_Sibling.
3403
3404 2017-04-28  Hristian Kirtchev  <kirtchev@adacore.com>
3405
3406         * erroutc.adb (Compilation_Errors): Do not consider info messages
3407         as suitable warnings when warnings must be treated as errors.
3408         * sem_ch7.adb (Analyze_Package_Specification): Do not consider
3409         internally-generated packages when outputting completion
3410         information.
3411         * errout.adb (Output_Messages): Do not consider info messages as
3412         suitable warnings when warnings must be treated as errors.
3413         * errutil.adb (Finalize): Do not consider info messages as
3414         suitable warnings when warnings must be treated as errors.
3415
3416 2017-04-28  Eric Botcazou  <ebotcazou@adacore.com>
3417
3418         * warnsw.ads: Minor fix for incorrect wording in comment.
3419
3420 2017-04-28  Ed Schonberg  <schonberg@adacore.com>
3421
3422         * sem_res.adb (In_Instance_Code): New predicate in
3423         Valid_Conversion, to determine whether a type conversion appears
3424         as (or within) an actual for a formal object.  Type conversions
3425         in instances are not rechecked in Valid_Conversion because
3426         visibility changes between generic location andi instance may
3427         lead to spurious errors, but conversions within an actual must be
3428         fully checked, and they are not fully resolved when pre-analyzing
3429         the actuals.
3430
3431 2017-04-28  Hristian Kirtchev  <kirtchev@adacore.com>
3432
3433         * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
3434         New_Copy_Tree instead of Relocate_Node as any subsequent copies
3435         of the relocated node will have mangled Parent pointers.
3436         * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
3437         tables used in conjunction with entity and itype replication.
3438         (Visit_Entity): Rewrite the restriction on which entities
3439         require duplication.  The restriction now includes all types.
3440
3441 2017-04-28  Hristian Kirtchev  <kirtchev@adacore.com>

3460
3461 2017-04-27  Tristan Gingold  <gingold@adacore.com>
3462
3463         * gcc-interface/Make-lang.in: Define EH_MECHANISM while building
3464         raise-gcc.c. Fix include search path for raise-gcc.c
3465
3466 2017-04-27  Eric Botcazou  <ebotcazou@adacore.com>
3467

3493         For efficiency, cache results of Is_Internal_File_Name and
3494         Is_Predefined_File_Name in the Units table. This avoids a lot
3495         of repeated text processing.

3497 2017-04-27  Emmanuel Briot  <briot@adacore.com>
3498

3502
3503         * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
3504         allow the use of regular equality over elements in contracts.
3505         (Formal_Model): Ghost package containing model functions that are
3506         used in subprogram contracts.

3526 2017-04-27  Ed Schonberg  <schonberg@adacore.com>
3527
3528         * exp_util.adb (Replace_Entity): The prefix of a 'Result
3529         attribute reference in a post- condition is the subprogram to
3530         which the condition applies. If the condition is inherited
3531         by a type extension, the prefix becomes a reference to the
3532         inherited operation, but there is no need to create a wrapper
3533         for this operation, because 'Result is expanded independently
3534         when elaborating the postconditions.
3535
3536 2017-04-27  Bob Duff  <duff@adacore.com>
3537
3538         * sinput.adb: Minor code cleanup.
3539         * namet.adb (Append): Create faster versions of
3540         Append(String) and Append(Name_Id) by using slice assignment
3541         instead of loops.
3542         * sem_util.adb (In_Instance): Speed this up by removing
3543         unnecessary tests; Is_Generic_Instance is defined for all
3544         entities.
3545         * sem_util.ads, sem_util.adb (In_Parameter_Specification):
3546         Remove unused function.
3547         * alloc.ads (Nodes_Initial): Use a much larger value, because
3548         the compiler was spending a lot of time copying the nodes table
3549         when it grows. This number was chosen in 1996, so is rather out
3550         of date with current memory sizes. Anyway, it's virtual memory.
3551         Get rid of Orig_Nodes_...; use Node_... instead.
3552         * atree.adb (Lock): Do not release the Nodes tables; it's a
3553         waste of time.
3554         Orig_Nodes_ ==> Nodes_
3555         * nlists.adb: Orig_Nodes_ ==> Nodes_
3556         * g-table.adb: Remove unused "with" clause.
3557         * g-table.ads, table.ads: Remove Big_Table_Type, which should
3558         not be used by clients.
3559         * g-dyntab.adb (Last_Allocated): New function
3560         to encapsulate T.P.Last_Allocated, which I'm thinking of changing.

3598
3599         * exp_disp.adb (Build_Class_Wide_Check): New subsidiary
3600         of Expand_Dispatching_Call. If the denoted subprogram has a
3601         class-wide precondition, this is the only precondition that
3602         applies to the call, rather that the class-wide preconditions
3603         that may apply to the body that is executed. (This is specified
3604         in AI12-0195).

3614         * sem_prag.adb (Inherit_Class_Wide_Pre): If the parent operation

3616         so examine its parent operation which is its Alias.
3617
3618 2017-04-27  Ed Schonberg  <schonberg@adacore.com>
3619
3620         * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
3621         prefix can be an object reference in which case Obj'Image (X)
3622         can only be interpreted as an indexing of the parameterless
3623         version of the attribute.
3624         * par-ch4.adb (P_Name): An attribute reference can be the prefix of
3625         an indexing or a slice operation if the attribute does not require
3626         parameters. In Ada2012 'Image also belongs in this category,
3627         and A'Image (lo .. hi) is legal and must be parsed as a slice.

3633         disable the CodePeer and C generation modes. Similar to the
3634         opposite actions done in CodePeer mode.

3660         point back to the empty array. Code cleanups.

3976         clone. The inherited operation becomes a similar wrapper to which
3977         modified conditions apply, and the call to the clone includes

3997         gets the modified conditions.
3998         * contracts.adb (Analyze_Contracts): If analysis of classwide
3999         condition has created a clone for a primitive operation, analyze

4186         to improve readablity. Subprograms are separated between basic
4187         operations, constructors and properties. Universally quantified

4224
4225         * exp_ch7.adb (Establish_Transient_Scope): Rewrite
4226         the loop which detects potential enclosing transient scopes. The
4227         loop now terminates much earlier as transient scopes are bounded
4228         by packages and subprograms.
4229

4235         model functions.
4236         (Formal_Model): Ghost package containing
4237         model functions that are used in subprogram contracts.

4285 2017-04-27  Hristian Kirtchev  <kirtchev@adacore.com>
4286
4287         * debug.adb Change the documentation of switch -gnatd.s.
4288         * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
4289         to manage the secondary stack when an enclosing scope already
4290         performs this functionality (aka relaxed management). Switch
4291         -gnatd.s may be used to force strict management in which case
4292         the block will manage the secondary stack unconditionally. Add
4293         a guard to stop the traversal when encountering a package or a
4294         subprogram scope.
4295
4296 2017-04-27  Ed Schonberg  <schonberg@adacore.com>
4297
4298         * sem_res.adb (Resolve_Call): Refine further the handling of
4299         limited views of return types in function calls. If the function
4300         that returns a limited view appears in the current unit,
4301         we do not replace its type by the non-limited view because
4302         this transformation is performed int the back-end. However,
4303         the type of the call itself must be the non-limited view, to
4304         prevent spurious resolution errors.
4305

4307
4308         * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
4309         Removed, proposed implementation using generics for class-wide
4310         preconditions proved impractical.
4311         (Class_Wide_Clone): New attribute of subprogram. Designates
4312         subprogram created for primitive operations with class-wide
4313         pre/postconditions that contain calls to other primitives. The
4314         clone holds the body of the original primitive, but the
4315         pre/postonditions do not apply to it. The original body is
4316         rewritten as a wrapper for a call to the clone.
4317         (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
4318         the flag is set, no code for the corresponding pre/postconditions
4319         is inserted into its body.

4503         * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
4504         checking, for source buffers.  Modify representation clause for
4505         Source_File_Record as appropriate.  Move Source_File_Index_Table
4506         from spec to body, because it is not used outside the body.

5274         the spec when it needs to ignore all SPARK_Mode pragmas found

5389
5390         * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
5391         Minor reformatting.
5392
5393 2017-04-25  Bob Duff  <duff@adacore.com>
5394
5395         * sem_prag.adb (No_Return): Give an error if the pragma applies
5396         to a body. Specialize the error for the specless body case,
5397         as is done for (e.g.) pragma Convention.
5398         * debug.adb: Add switch -gnatd.J to disable the above legality
5399         checks. This is mainly for use in our test suite, to avoid
5400         rewriting a lot of illegal (but working) code.  It might also
5401         be useful to customers. Under this switch, if a pragma No_Return
5402         applies to a body, and the procedure raises an exception (as it
5403         should), the pragma has no effect. If the procedure does return,
5404         execution is erroneous.
5405
5406 2017-04-25  Bob Duff  <duff@adacore.com>
5407
5408         * exp_ch6.adb (Expand_Actuals): This is the
5409         root of the problem. It took N as an 'in out' parameter, and in
5410         some cases, rewrote N, but then set N to Original_Node(N). So
5411         the node returned in N had no Parent. The caller continued
5412         processing of this orphaned node. In some cases that caused a
5413         crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
5414         and trips over the Empty Parent). The solution is to make N an
5415         'in' parameter.  Instead of rewriting it, return the list of
5416         post-call actions, so the caller can do the rewriting later,
5417         after N has been fully processed.
5418         (Expand_Call_Helper): Move most of Expand_Call here. It has
5419         too many premature 'return' statements, and we want to do the
5420         rewriting on return.
5421         (Insert_Post_Call_Actions): New procedure to insert the post-call
5422         actions in the appropriate place. In the problematic case,
5423         that involves rewriting N as an Expression_With_Actions.
5424         (Expand_Call): Call the new procedures Expand_Call_Helper and
5425         Insert_Post_Call_Actions.

5433 2017-04-25  Javier Miranda  <miranda@adacore.com>

5436         support for renamings and functions that return a constrained
5437         array type (i.e. functions for which the frontend built a
5438         procedure with an extra out parameter).

5458         * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
5459         convention Stdcall, which has a number of exceptions. Convention
5460         is legal on a component declaration whose type is an anonymous
5461         access to subprogram.

5479         * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
5480         that its parent type has a private extension.
5481         * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
5482         New subprogram.

5495 2017-04-25  Bob Duff  <duff@adacore.com>
5496
5497         * s-fileio.adb (Close): When a temp file is
5498         closed, delete it and clean up its Temp_File_Record immediately,
5499         rather than waiting until later.
5500         (Temp_File_Record): Add File
5501         component, so Close can know which Temp_File_Record corresponds
5502         to the file being closed.
5503         (Delete): Don't delete temp files,
5504         because they are deleted by Close.
5505         (Open): Set the File component
5506         of Temp_File_Record. This requires moving the creation of the
5507         Temp_File_Record to the end, after the AFCB has been created.

5536         conversions from float to integer in GNATprove mode.
5537         (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
5538         to call Apply_Type_Conversion_Checks, so that range checks
5539         are properly positioned when needed on conversions, including
5540         when converting from float to integer.  (Determine_Range): In
5541         GNATprove mode, take into account the possibility of conversion
5542         from float to integer.
5543         * sem_res.adb (Resolve_Type_Conversion): Only enforce range
5544         check on conversions from fixed-point to integer, not anymore

5592         * sem_ch8.adb (Use_One_Type): If a use_type_clause
5593         is redundant, set its Used_Operations to empty. This is only
5594         necessary for use clauses that appear in the parent of a generic
5595         child unit, because those use clauses get reanalyzed when we
5596         instantiate the generic, and we don't want the Used_Operations
5597         carried over from the original context (where it was probably
5598         not redundant).

5660         handle the proposed changes to rules concerning potentially
5661         unevaluated expressions, to include selected components that

5772         Stop. Was using Current_Source_File, which is only valid during
5773         parsing. Current_Source_File will have a leftover value from

5782         with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
5783         because Should_Ignore_Pragma was not working reliably outside
5784         the parser, because Current_Source_File is not valid.
5785         * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.

5856         of prefix whose type is a current instance of a synchronized
5857         type. If the prefix is an object this is an external call (or
5858         requeue) that can only access public operations of the object. The
5859         previous predicate was too restrictive, and did not allow public

5866 2017-04-25  Hristian Kirtchev  <kirtchev@adacore.com>
5867
5868         * einfo.adb (Is_Anonymous_Access_Type): New routine.
5869         * einfo.ads Update the placement of
5870         E_Anonymous_Access_Subprogram_Type along with all subtypes that
5871         mention the ekind.
5872         (Is_Anonymous_Access_Type): New routine.
5873         * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
5874         master for an access type subject to pragma No_Heap_Finalization.
5875         * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
5876         allocated or deallocated does not finalization actions if the
5877         associated access type is subject to pragma No_Heap_Finalization.
5878         * opt.ads Add new global variable No_Heap_Finalization_Pragma.
5879         * par-prag.adb Pragma No_Heap_Finalization does not need special
5880         processing from the parser.
5881         * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
5882         ??? comments. Use the new predicate Is_Anonymous_Access_Type.
5883         * sem_prag.adb Add an entry in table Sig_Flags for pragma
5884         No_Heap_Finalization.
5885         (Analyze_Pragma): Add processing for
5886         pragma No_Heap_Finalization. Update various error messages to
5887         use Duplication_Error.
5888         * sem_util.ads, sem_util.adb (No_Heap_Finalization): New routine.
5889         * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
5890         and corresponding pragma id.
5891
5892 2017-04-25  Bob Duff  <duff@adacore.com>
5893
5894         * freeze.adb (Freeze_Record_Type): Use the
5895         underlying type of the component type to determine whether it's
5896         elementary. For representation clause purposes, a private type
5897         should behave the same as its full type.
5898         * fname.ads, fname.adb (Is_Predefined_File_Name):
5899         Make sure things like "system.ali" are recognized as predefined.
5900
5901 2017-04-25  Javier Miranda  <miranda@adacore.com>
5902
5903         * debug.adb: Update documentation of -gnatd.6.
5904
5905 2017-04-25  Ed Schonberg  <schonberg@adacore.com>
5906
5907         * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
5908         element iterator when the name is an overloaded function call,
5909         one of whose interpretations yields an array.
5910
5911 2017-04-25  Bob Duff  <duff@adacore.com>
5912
5913         * uname.ads, uname.adb (Is_Predefined_Unit_Name,
5914         Is_Internal_Unit_Name): New functions for operating on unit
5915         names, as opposed to file names. There's some duplicated code
5916         with fname.adb, which is unfortunate, but it seems like we don't
5917         want to add dependencies here.
5918         * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
5919         to Is_Predefined_Unit_Name; the former was wrong, because Uname
5920         is not a file name at all.
5921         * fname.ads, fname.adb: Document the fact that
5922         Is_Predefined_File_Name and Is_Internal_File_Name can be called
5923         for ALI files, and fix the code so it works properly for ALI
5924         files. E.g. these should return True for "system.ali".
5925
5926 2017-04-25  Justin Squirek  <squirek@adacore.com>
5927
5928         * exp_util.adb (Add_Invariant): Removed,
5929         code moved to Add_Invariant_Check, Add_Inherited_Invariant,
5930         and Add_Own_Invariant.  (Add_Invariant_Check): Used
5931         for adding runtime checks from any kind of invariant.
5932         (Add_Inherited_Invariant): Generates invariant checks for
5933         class-wide invariants (Add_Interface_Invariants): Removed, code
5934         moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):
5935         Create a types own invariant procedure (Add_Parent_Invariants):
5936         Removed, code moved to Build_Invariant_Procedure_Body
5937         (Build_Invariant_Procedure_Body): Add refactored calls
5938         and integrated code from Add_Parent_Invariants and
5939         Add_Interface_Invariants.
5940         (Process_Type): Removed, the
5941         relavant code was inlined into both Add_Own_Invariant and
5942         Add_Inherited_Invariant.
5943
5944 2017-04-25  Hristian Kirtchev  <kirtchev@adacore.com>

5948
5949 2017-04-25  Pascal Obry  <obry@adacore.com>
5950
5951         * s-taprop-mingw.adb: Do not check for CloseHandle in

5957         Continue to examine the context if the reference appears within
5958         an expression function.
5959
5960 2017-04-25  Justin Squirek  <squirek@adacore.com>
5961
5962         * exp_ch7.adb, exp_ch7.ads Remove Build_Invariant_Procedure_Body
5963         and Build_Invariant_Procedure_Declaration.
5964         * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
5965         and Build_Invariant_Procedure_Declaration from exp_ch7
5966         and break-out Is_Untagged_Private_Derivation from
5967         Build_Invariant_Procedure_Body.
5968         (Replace_Type_References):
5969         Append an extra parameter to allow for dispatching replacements
5970         and add the corrasponding logic.
5971         (Type_Invariant): Remove
5972         Replace_Typ_Refs and replace its references with calls to
5973         Replace_Type_References.
5974         * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
5975
5976 2017-04-25  Bob Duff  <duff@adacore.com>
5977
5978         * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): New function
5979         that returns True when appropriate.
5980         * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
5981         when compiling predefined files.
5982         * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
5983         "gnat.adc" should not be considered a predefined file name.
5984         That required (or at least encouraged) a lot of cleanup of global
5985         variable usage. We shouldn't be communicating information via
5986         the global name buffer.
5987         * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
5988         * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

6008         * stringt.ads, stringt.adb, exp_dbug.adb, sem_dim.adb: Remove
6009         Add_String_To_Name_Buffer, to avoid using the global Name_Buf.
6010         Add String_To_Name with no side effects.

6019         * par-ch2.adb, scans.ads, scn.adb: Do not give an error for
6020         reserved words inside pragmas. This is necessary to allow the
6021         pragma name Interface to be used in pragma Ignore_Pragma.
6022         * par.adb: Minor comment fix.
6023
6024 2017-04-25  Javier Miranda  <miranda@adacore.com>

6048         the first pass over an assignment statement with target names,
6049         to prevent the generation of subtypes (such as discriminated
6050         record components)that may carry the target name outside of the
6051         tree for the assignment. The subtypes will be generated when
6052         the assignment is reanalyzed in full.
6053         (Analyze_Target_Name): Handle properly class-wide types.
6054

6062         (Add_Inherited_Tagged_DIC): There is really no need to preanalyze
6063         and resolve the triaged expression because all substitutions
6064         refer to the proper entities.  Update the replacement of
6065         references.
6066         (Build_DIC_Procedure_Body): Add formal parameter
6067         For_Freeze. Add local variable Build_Body. Inherited DIC pragmas
6068         are now only processed when freezing occurs.  Build a body only
6069         when one is needed.
6070         (Entity_Hash): Removed.
6071         (Map_Types): New routine.

6084         * sem_ch7.adb (Preserve_Full_Attributes): Propagate the DIC
6085         properties of the private type to the full view in case the full
6086         view derives from a parent type and inherits a DIC pragma.
6087         * sem_prag.adb (Analyze_Pragma): Guard against a case where a
6088         DIC pragma is placed at the top of a declarative region.
6089
6090 2017-04-25  Arnaud Charlet  <charlet@adacore.com trojanek>
6091
6092         * a-tasatt.adb: Complete previous change and use an unsigned

6094
6095 2017-04-25  Ed Schonberg  <schonberg@adacore.com>
6096
6097         * sem_attr.adb (Analyze_Attribute, case 'Access): Specialize
6098         the error message when the attribute reference is an actual in
6099         a call to a subprogram inherited from a generic formal type with
6100         unknown discriminants, which makes the subprogram and its formal
6101         parameters intrinsic (see RM 6.3.1 (8) and (13)).
6102
6103 2017-04-25  Hristian Kirtchev  <kirtchev@adacore.com>
6104
6105         * sem_aggr.adb, inline.adb, einfo.adb, einfo.ads, scng.adb,

6107
6108 2017-04-25  Bob Duff  <duff@adacore.com>
6109
6110         * sem_attr.adb (Type_Key): Add code in the
6111         recursive Compute_Type_Key to protect against fetching the source
6112         code for Standard, in case a component of the type is declared
6113         in Standard. There was already code to do this for the original
6114         type, but not for its components.
6115

6125         real conditional expression can appear in a fixed-type context
6126         and must be resolved with that context to facilitate the code
6127         generation to the backend.

6130
6131         * einfo.adb, einfo.ads (Body_Needed_For_Inlining): New flag,
6132         to indicate whether during inline processing, when some unit U1
6133         appears in the context of a unit U2 compiled for instantiation
6134         or inlining purposes, the body of U1 needs to be compiled as well.
6135         * sem_prag.adb (Process_Inline): Set Body_Needed_For_Inlining if
6136         context is a package declaration.

6148         enclosing assignment node accordingly.
6149         * par-ch5.adb (P_Assignment_Statement): Set Current_Assign_Node
6150         appropriately.
6151         * sem_ch5.adb (Analyze_Assignment): Disable expansion before
6152         analyzing RHS if the statement has target_names.
6153         * sem_aggr.adb (Resolve_Iterated_Component_Association): Handle
6154         properly choices that are subtype marks.

6228         (Build_DIC_Procedure_Body): Add formal parameter

6247         properties of the private type to the full view in case the full
6248         view derives from a parent type and inherits a DIC pragma.
6249         * sem_prag.adb (Analyze_Pragma): Guard against a case where a
6250         DIC pragma is placed at the top of a declarative region.

6271         be constructed for an inherited primitive whose inherited
6272         pre/postcondition has called to overridden primitives.
6273         * freeze.adb (Check_Inherited_Conditions): Build wrapper body
6274         for inherited primitive that requires it.
6275         * sem_disp.adb (Check_Dispatching_Operation): Such wrappers are
6276         legal primitive operations and belong to the list of bodies
6277         generated after the freeze point of a type.
6278         * sem_prag.adb (Build_Pragma_Check_Equivalent): Use new signature

6297         Handle properly a multi- level derivation involving both renamed
6298         and constrained parent discriminants, when the type to be
6299         constrained has fewer discriminants that the ultimate ancestor.

6330
6331         * sem_util.adb (New_Copy_Tree): By default
6332         copying of defining identifiers is prohibited because
6333         this would introduce an entirely new entity into the
6334         tree. This patch introduces an exception to this general
6335         rule: the declaration of constants and variables located in
6336         Expression_With_Action nodes.
6337         (Copy_Itype_With_Replacement): Renamed as Copy_Entity_With_Replacement.

6891         * sem_res.adb (Resolve_Call): In the part of the code where
6892         it is deciding whether to turn the call into an indexed
6893         component, avoid doing so if the call is to an instance of
6894         Unchecked_Conversion. Otherwise, the compiler turns it into an
6895         indexed component, and resolution of that turns it back into a
6896         function call, and so on, resulting in infinite recursion.
6897         * sem_util.adb (Needs_One_Actual): If the first formal has a
6898         default, then return False.

6936
6937         * exp_ch9.adb: minor style fixes in comments.
6938         * sem_ch9.adb (Analyze_Delay_Relative): in GNATprove mode a delay

6946         must be treated as delayed aspect even if the expression is
6947         a literal, because the aspect affects the freezing and the
6948         elaboration of the object to which it applies.

6998
6999         * sem_res.adb (Resolve_Call): If a function call
7000         returns a limited view of a type and at the point of the call the
7001         function is not declared in the extended main unit then replace
7002         it with the non-limited view, which must be available. If the
7003         called function is in the extended main unit then no action is
7004         needed since the back-end handles this case.

7017
7018         * sem_ch3.adb (Complete_Private_Subtype): If the scope of the
7019         base type differs from that of the completion and the private
7020         subtype is an itype (created for a constraint on an access

7577         enable by the -dp switch, or by modifying the Do_Old and Do_New
7578         etc. flags and rebuilding. Experimental code is included to
7579         compare the results of the old and new algorithms.
7580         * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
7581         can have multiple of these tables, so the old and new algorithms
7582         can coexist.
7583         * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
7584         parameter of type array. This avoids the global variable, and
7585         allows bounds checking (which is normally defeated by the tables
7586         packages). It also ensures that the Elab_Order is read-only
7587         to Bindgen.
7588         * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
7589         subprograms that need it, as above.
7590         * debug.adb: Document new -dp switch. Modify doc of old -do
7591         switch.
7592         * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
7593         and Bindgen.  Move writing of closure (-R and -Ra switches)
7594         to Binde; that's more convenient.

7596 2017-01-13  Ed Schonberg  <schonberg@adacore.com>
7597
7598         * sem_ch6.adb (Analyze_Expression_Function): If the expression
7599         function is a completion, all entities referenced in the
7600         expression are frozen. As a consequence, a reference to an
7601         uncompleted private type from an enclosing scope is illegal.

7604
7605         * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
7606         (Analyze_Subprogram_Body_Helper): At the occurrence of an
7607         expression function declaration that is a completion, its
7608         expression causes freezing (AI12-0103).

7620
7621         * exp_ch3.adb (Default_Initialize_Object): Do not default
7622         initialize an object when it is of a task type and restriction
7623         No_Tasking is in effect because the initialization is obsolete.
7624         * exp_ch9.adb (Build_Master_Entity): Do not generate a master when
7625         restriction No_Tasking is in effect.
7626         (Build_Master_Renaming): Do not rename a master when restriction
7627         No_Tasking is in effect.

7630
7631         * sem_aggr.adb (Resolve_Array_Aggregate): The code that verifies
7632         the legality of An others clause applies as well to a choice in
7633         an Iterated_component_ association.
7634         (Resolve_Iterated_Component_Association): An others choice
7635         is legal.
7636         * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An

7659
7660         * sem_util.ads, sem_util.adb (Choice_List): Move function here

7667         (Gen_Loop): Generate proper loop for an
7668         Iterated_Component_Association: loop variable has the identifier
7669         of the original association. Generate a loop even for a single
7670         component choice, in order to make loop parameter visible in
7671         expression.
7672         (Flatten): An Iterated_Component_Association is not static.
7673
7674 2017-01-13  Yannick Moy  <moy@adacore.com>
7675
7676         * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
7677         float exponentiation for statically known small negative values
7678         is the reciprocal of the exponentiation for the opposite value
7679         of the exponent.
7680         * s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):
7681         Ensure that the value of float exponentiation for negative values
7682         is the reciprocal of the exponentiation for the opposite value
7683         of the exponent.
7684         * inline.adb (Expand_Inlined_Call): Fix the count
7685         for the number of generated gotos.
7686
7687 2017-01-13  Yannick Moy  <moy@adacore.com>
7688

7694
7695         * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
7696         mode a choice that is a subtype with a static predicate is
7697         replaced by the values it covers. This transformation must not
7698         be performed in ASIS mode, to preserve the source for analysis.
7699
7700 2017-01-13  Justin Squirek  <squirek@adacore.com>
7701
7702         * nlists.ads: Correct minor typo.

7709
7710         * par-ch4.adb (P_Aggregate_Or_Parent_Expr): An
7711         Iterated_Component_Association is a named association in an
7712         array aggregate.
7713         * sem_aggr.adb (Resolve_Iterated_Component_Association): New
7714         procedure, subsidiary of Resolve_Array_Aggregate, to analyze
7715         and resolve the discrete choices and the expression of the
7716         new construct.
7717         * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
7718         Loop_Actions and Box_Present are attributes of
7719         N_Iterated_Component_Association nodes. Box_Present is always
7720         False in this case.
7721         * sprint.adb (Sprint_Node): An Iterated_Component_Association
7722         has a Discrete_Choices list, as specified in the RM. A
7723         Component_Association for aggregate uses instead a Choices list.
7724         We have to live with this small inconsistency because the new
7725         construct also has a defining identifier, and there is no way
7726         to merge the two node structures.
7727

7735 2017-01-13  Ed Schonberg  <schonberg@adacore.com>
7736
7737         * sem_ch3.adb (Resolve_Aspects): New procedure, subsidiary of
7738         Analyze_Declarations, to analyze and resolve the expressions of
7739         aspect specifications in the current declarative list, so that
7740         the expressions have proper entity and type info.  This is needed
7741         for ASIS when there is no subsequent expansion to generate this
7742         semantic information.
7743         * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
7744         original expression, to suppress cascaded errors when expression
7745         has been constant-folded.
7746         (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
7747         ASIS mode, because there is no subsequent expansion to decorate
7748         the tree.
7749
7750 2017-01-13  Yannick Moy  <moy@adacore.com>
7751
7752         * inline.adb, inline.ads (Call_Can_Be_Inlined_In_GNATprove_Mode):
7753         New function to detect when a call may be inlined or not in
7754         GNATprove mode.
7755         (Expand_Inlined_Call): Ensure that a temporary
7756         is always created in the cases where a type conversion may be
7757         needed on an input parameter in GNATprove mode, so that GNATprove
7758         sees the check to perform.
7759         * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
7760         when not applicable due to actual requiring type conversion
7761         with possible check but no temporary value can be copied for
7762         GNATprove to see the check.

8896         run-time errors, e.g. in case statements. This is relevant when
8897         the expression is the result of constant-folding a type conversion
8898         whose expression is a variable with a known static value.
