547 * freeze.adb (Check_Component_Storage_Order): Default initialize
548 Comp_Byte_Aligned rather than silencing messages with pragma
549 Warnings(Off), which does not work for CodePeer initialization
550 messages, and given that here the possible read of an unitialized value
551 depends on a proper use of parameters by the caller.
552 * inline.adb (Expand_Inlined_Call): Default initialize Lab_Decl, Targ.

565 uninitialized Obj_Decl.
566 * sem_ch9.adb (Analyze_Requeue): Default initialize Synch_Type.
567 (Check_Interfaces): Default initialize Full_T_Ifaces and Priv_T_Ifaces,
568 which seem to be left uninitialized and possibly read in some cases.
569 * sem_dim.adb (Analyze_Aspect_Dimension_System): Retype Position more
570 precisely. This requires to exchange the test for exiting in case of
571 too many positions and the increment to Position, inside the loop.
572 * sem_eval.adb (Eval_Concatenation): Default initialize Folded_Val,
573 which cannot be read uninitialized, but the reasons for that are quite
575 * sem_intr.adb (Check_Intrinsic_Call): Default initialize Rtyp.

578 * sem_res.adb (Make_Call_Into_Operator): Default initialize Opnd_Type,
579 and test for presence of non-null Opnd_Type before testing its scope,

617 * namet.ads, namet.adb (Valid_Name_Id): New subtype that excludes
618 Error_Name and No_Name. Use this (versus Name_Id) to indicate which
619 objects can have those special values. Valid_Name_Id could usefully be
620 used all over the compiler front end, but that's too much trouble for
621 now. If we did that, we might want to rename:
622 Name_Id --> Optional_Name_Id, Valid_Name_Id --> Name_Id.
623 For parameters of type Valid_Name_Id, remove some redundant tests,
624 including the ones found by CodePeer. Use Is_Valid_Name instead of
625 membership test when appropriate.
626 (Error_Name_Or_No_Name): Delete this; it's no longer needed.
627 * sem_ch2.adb (Analyze_Identifier): Use "not Is_Valid_Name" instead of
628 "in Error_Name_Or_No_Name".

1994 * exp_ch6.adb: (Make_Build_In_Place_Call_In_Object_Declaration): Take
1995 care of unchecked conversions in addition to regular conversions. This
1996 takes care of a case where a type is derived from a private untagged
1997 type that is completed by a tagged controlled type.
1999 2017-10-09 Ed Schonberg <schonberg@adacore.com>
2001 * exp_disp.adb (Build_Class_Wide_Check, Replace_Formals): When
2002 rewriting a class-wide condition, handle properly the case where the
2003 controlling argument of the operation to which the condition applies is
2004 an access to a tagged type, and the condition includes a dispatching
2005 call with an implicit dereference.

2016 * sem_ch4.adb (Try_Class_Wide_Operation, Traverse_Homonyms):
2017 Suppress spurious ambiguity error when two traversals of the homonym
2018 chain (first directly, and then through an examination of relevant
2019 interfaces) retrieve the same operation, when other irrelevant homonyms
2020 of the operatioh are also present.
2022 2017-10-09 Ed Schonberg <schonberg@adacore.com>
2024 * sem_util.adb (Object_Access_Level): If the object is the return
2025 statement of an expression function, return the level of the function.
2026 This is relevant when the object involves an implicit conversion
2027 between access types and the expression function is a completion, which
2028 forces the analysis of the expression before rewriting it as a body, so
2029 that freeze nodes can appear in the proper scope.
2031 2017-10-09 Bob Duff <duff@adacore.com>
2033 * atree.adb: Make nnd apply to everything "interesting", including
2034 Rewrite. Remove rrd.

2038 * exp_ch3.adb (Expand_N_Object_Declaration): Avoid never-ending loop
2039 processing the declaration of the dummy object internally created by
2040 Make_DT to compute the offset to the top of components referencing
2041 secondary dispatch tables.
2042 (Initialize_Tag): Do not initialize the offset-to-top field if it has
2043 been initialized initialized.
2044 * exp_disp.ads (Building_Static_Secondary_DT): New subprogram.
2045 * exp_disp.adb (Building_Static_Secondary_DT): New subprogram.
2046 (Make_DT): Create a dummy constant object if we can statically build
2047 secondary dispatch tables.
2048 (Make_Secondary_DT): For statically allocated secondary dispatch tables
2049 use the dummy object to compute the offset-to-top field value by means
2050 of the attribute 'Position.
2052 2017-10-09 Bob Duff <duff@adacore.com>
2054 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Add self-checking
2055 code so if BIPAlloc is not passed in, it will likely raise
2056 Program_Error instead of cause miscellaneous chaos.
2057 (Is_Build_In_Place_Result_Type): Return False if not Expander_Active,
2058 as for the other Is_B-I-P... functions.
2059 * sem_aggr.adb (Resolve_Extension_Aggregate): For an extension
2060 aggregate whose ancestor part is a build-in-place call returning a
2061 nonlimited type, transform the assignment to the ancestor part to use a
2063 * sem_ch3.adb (Build_Itype_Reference): Handle the case where we're
2064 creating an Itype for a library unit entity.
2065 (Check_Initialization): Avoid spurious error message on
2066 internally-generated call.
2067 * sem_ch5.adb (Analyze_Assignment): Handle the case where the
2068 right-hand side is a build-in-place call. This didn't happen when b-i-p
2069 was only for limited types.
2070 * sem_ch6.adb (Create_Extra_Formals): Remove assumption that b-i-p
2071 implies >= Ada 2005.
2072 * sem_ch7.adb (Scan_Subprogram_Refs): Avoid traversing the same nodes

2100 actual for a formal package is an instantiation of a child unit, create
2101 a freeze node for the instance of the parent if it appears in the same
2102 scope and is not frozen yet.
2104 2017-10-09 Pierre-Marie de Rodat <derodat@adacore.com>
2106 * exp_atag.ads, libgnat/a-tags.adb, libgnat/a-tags.ads: Enhance
2107 in-source documentation for tagged types's Offset_To_Top.
2109 2017-10-09 Bob Duff <duff@adacore.com>
2111 * exp_ch3.adb (Build_Assignment): Parameter name N was somewhat
2112 confusing. Same for N_Loc. Remove assumption that b-i-p implies
2113 limited. This is for the case of a function call that occurs as the
2114 default for a record component.
2115 (Expand_N_Object_Declaration): Deal with the case where expansion has
2116 created an object declaration initialized with something like
2118 * exp_ch3.adb: Minor reformatting.
2120 2017-10-09 Ed Schonberg <schonberg@adacore.com>
2122 * exp_attr.adb (Expand_Attribute_Reference, case 'Valid): The prefix of
2123 the attribute is an object, but it may appear within a conversion. The
2124 object itself must be retrieved when generating the range test that
2125 implements the validity check on a scalar type.
2127 2017-10-05 Eric Botcazou <ebotcazou@adacore.com>
2130 * mingw32.h (_O_U8TEXT, _O_U16TEXT, _O_WTEXT): Delete.

2149 * exp_ch6.adb (Expand_Call_Helper): Replace with code more similar to
2151 (Make_Build_In_Place_Call_In_Object_Declaration): Back out previous
2152 change. Set the Etype in the class-wide case. This fixes a regression
2153 in the libadalang test suite.

2178 * exp_ch6.adb (Expand_Call_Helper): Handle case of build-in-place
2179 functions returning nonlimited types. Allow for qualified expressions
2180 and type conversions.
2181 (Expand_N_Extended_Return_Statement): Correct the computation of

2186 (Is_Build_In_Place_Result_Type): New function to accompany
2187 Is_Build_In_Place_Function and Is_Build_In_Place_Function_Call, because
2188 sometimes we just have the type on our hands, not the function. For
2189 now, does the same thing as the old version, so build-in-place is
2190 disabled for nonlimited types, except that you can use -gnatd.9 to
2192 * exp_ch6.ads (Is_Build_In_Place_Result_Type): New function to
2193 accompany Is_Build_In_Place_Function and
2194 Is_Build_In_Place_Function_Call, because sometimes we just have the
2195 type on our hands, not the function.
2196 (Make_Build_In_Place_Call_In_...): Handle nonlimited build-in-place
2198 (Make_Build_In_Place_Call_In_Object_Declaration): Remove the
2199 questionable code at the end that was setting the Etype.
2200 * exp_aggr.adb (Is_Build_In_Place_Aggregate_Return): New function to
2201 determine whether "return (...agg...);" is returning from a
2202 build-in-place function.

2204 Remove assumption that b-i-p implies limited (initialization of
2205 In_Place_Expansion).
2206 (Build_Record_Aggr_Code): AI-287: fix comment; it can't be wrapped in
2207 an unchecked conversion. Add assertions.
2208 (Convert_Aggr_In_Object_Decl): Establish_Transient_Scope -- no need for
2209 secondary stack here, just because the type needs finalization. That
2211 (Convert_To_Assignments): Only set Unc_Decl if Nkind (N) = N_Aggregate.
2212 For "return (...agg...);" don't assume b-i-p implies limited.

2231 b-i-p implies >= Ada 2005.
2232 * exp_util.adb (Build_Allocate_Deallocate_Proc): Look at Storage_Pool
2233 (Expr), in case Pool_Id is not set.
2234 (Initialized_By_Aliased_BIP_Func_Call): Handle case where the call is
2235 qualified or converted.
2236 (Is_Secondary_Stack_BIP_Func_Call): Don't check if Nkind (Selector_Name
2237 (Param)) = N_Identifier; that's all it could be.
2238 * sinfo.ads: Comment fixes.
2239 * snames.ads-tmpl: Comment fixes.
2240 * debug.adb: Add flag gnatd.9, to enable the build-in-place machinery.

2267 * exp_aggr.adb: Remove calls to Set_No_Ctrl_Actions for discriminants.
2268 Discriminants can't need finalization.

2272 * sem_ch6.adb (Analyze_Expression_Function): Do not emit freeze nodes
2273 for types in expression if the function is within a generic unit.
2274 * sem_res.adb (Resolve): In a generic context do not freeze an
2275 expression, unless it is an entity. This exception is solely for the
2276 purpose of detecting illegal uses of deferred constants in generic

2348 given set is highest in scope (not always the most prev).
2349 (Use_One_Package, Use_One_Type): Major cleanup and reorganization to
2350 handle the new chaining algorithm, also many changes related to
2351 redundant clauses. A new parameter has also been added to force
2352 installation to handle certain cases.
2353 * sem_ch9.adb (Analyze_Entry_Body, Analyze_Protected_Body,
2354 Analyze_Task_Body): Mark use clauses on relevant entities.
2355 * sem_ch10.adb, sem_ch10.ads (Install_Context_Clauses,

2379 (rather than relocating it) to avoid resolving a potentially malformed
2380 tree when the expression is resolved through an ASIS-specific call to

3222 2017-09-08 Yannick Moy <moy@adacore.com>
3224 * sem_aux.adb, sem_aux.ads (Get_Called_Entity): New function to
3225 return the entity associated with the call.
3226 * sem_util.adb, sem_util.ads (Check_Function_Writable_Actuals):
3227 Replace the internal Get_Function_Id with the new
3228 Sem_Aux.Get_Called_Entity.
3229 (Iterate_Call_Parameters): New
3230 procedure to iterate on formals and actuals at the same time.
3231 * sem_ch12.adb (Analyze_Subprogram_Instantiation):
3232 Set SPARK_Mode from spec when set, for analysis
3233 of instance. Restore after analysis of instance.
3234 (Instantiate_Subprogram_Body): Set SPARK_Mode from body when
3235 set, for analysis of body instance. Restored automatically at
3236 the end of the subprogram.
3237 * gnat1drv.adb (Adjust_Global_Switches): Set
3238 Check_Validity_Of_Parameters to False in GNATprove mode.
3239 * opt.ads (Check_Validity_Of_Parameters): Document switch to
3242 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3244 * sem_util.adb (NCT_Tables_In_Use): Move to library level from...
3245 (New_Copy_Tree): ...there. Reset the hash tables only if they
3246 were used in the previous invocation.
3247 * s-htable.adb: Fix typo.
3249 2017-09-08 Bob Duff <duff@adacore.com>
3251 * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
3253 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3255 * sem_aggr.adb: minor style fix.
3257 2017-09-08 Bob Duff <duff@adacore.com>
3259 * sprint.adb (Write_Corresponding_Source): Ignore if there is
3260 no current source file.
3261 (Write_Name_With_Col_Check, Write_Name_With_Col_Check_Sloc):
3262 Print something helpful in case N is invalid.
3263 * sprint.ads: Minor comment fix.
3265 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3267 * exp_aggr.adb: (Aggr_Assignment_OK_For_Backend): Add early return for
3270 2017-09-08 Bob Duff <duff@adacore.com>
3272 * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
3273 Ada_2020, along the same lines as the other Ada version pragmas.
3275 2017-09-08 Gary Dismukes <dismukes@adacore.com>
3277 * sem_ch12.adb: Minor typo fixes and reformatting.
3279 2017-09-08 Yannick Moy <moy@adacore.com>
3281 * sem_aggr.adb (Resolve_Record_Aggregate):
3282 Rewrite bounds of aggregate subexpressions which may depend on
3283 discriminants of the enclosing aggregate.
3285 2017-09-08 Yannick Moy <moy@adacore.com>
3287 * sem_ch5.adb: Prevent assertion failure on illegal code.
3289 2017-09-08 Yannick Moy <moy@adacore.com>
3291 * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
3292 calling Renamed_Entity on an entity which cannot be a renaming.
3294 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3296 * exp_aggr.adb: Add with & use clause for Urealp.
3297 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
3298 elementary types instead of just discrete types.
3299 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
3300 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
3301 Be prepared for the FP zero value in the memset case. Add small
3304 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3306 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
3309 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
3311 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
3312 of New_Copy because the latter leaves the syntactic structure of
3313 the tree inconsistent (a child is accessible through two parents)
3314 and prevents proper replication of itypes by subsequent calls
3316 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
3317 New_Copy because the latter leaves the syntactic structure of the
3318 tree inconsistent (a child is accessible through two parents)
3319 and prevents proper replication of itypes by subsequent calls
3321 * sem_util.adb (In_Subtree): New routine.
3322 (New_Copy_Tree): Reimplemented.

3326 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3328 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
3329 for aspect Default_Value is a static scalar value, but it does
3330 not freeze the type. Yhis allows for subsequent representation
3331 clauses for the type.
3333 2017-09-08 Javier Miranda <miranda@adacore.com>
3335 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
3336 not add entries into the undefined reference table when we are
3337 compiling with errors ignored.
3339 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3341 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
3342 check if the instance is within an enclosing instance body. The
3343 formal package was legal in the enclosing generic, and is
3344 legal in the enclosing instantiation. This optimisation may be
3345 applicable elsewhere, and it also removes spurious errors that
3346 may arise with on-the-fly processing of instantiations that
3347 contain Inline_Always subprograms.
3349 2017-09-08 Vincent Celier <celier@adacore.com>
3351 * gnatcmd.adb: Disregard empty argument of GNAT driver.
3353 2017-09-08 Justin Squirek <squirek@adacore.com>
3355 * checks.adb (Insert_Valid_Check): Manually decorate
3356 the generated temporary for range valdity checks.
3358 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3360 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
3362 2017-09-08 Justin Squirek <squirek@adacore.com>
3364 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
3365 case to handle underscore flags.
3366 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
3367 new procedure to handle underscores.
3369 2017-09-08 Javier Miranda <miranda@adacore.com>
3371 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
3372 divisions with fixed point results to avoid generating twice
3373 the runtime check on divide by zero.
3374 * checks.adb (Apply_Divide_Checks): Ensure that operands are
3375 not evaluated twice (once for their runtime checks and once for
3376 their regular computation).
3378 2017-09-08 Yannick Moy <moy@adacore.com>
3380 * sem_prag.adb (Analyze_Part_Of): Add missing
3381 return statements after issuing errors. Add detection of
3382 out-of-order item and single concurrent type.

3512 when the actual is a construct that involves a dereference of an
3513 expression that includes a formal of the enclosing subprogram,

3526 exceptions instead of crashes. Check for absurdly long strings
3527 and empty strings. Empty strings cause trouble because they can
3528 have super-null ranges (e.g. 100..10), which causes Ext_Copy to
3529 be empty, which causes an array index out of bounds.

3776 a loop specification that is a subtype indication whose type mark
3777 is a type with a static predicate, inherit predicate function,
3778 used to build case statement for rewritten loop.
3780 2017-09-08 Justin Squirek <squirek@adacore.com>

3796 * exp_util.adb (Build_Invariant_Procedure_Declaration): If
3797 the type is an anonymous array in an object declaration, whose
3798 component type has an invariant, use the object declaration
3799 as the insertion point for the invariant procedure, given that
3800 there is no explicit type declaration for an anonymous array type.

3881 * errout.adb (Delete_Warning): Do not
3882 decrement Warnings_Treated_As_Errors. This is called before
3883 Warnings_Treated_As_Errors has been incremented to account for
3884 this warning. Decrementing it here can lead to negative values
3885 of Warnings_Treated_As_Errors, raising Constraint_Error in
3886 checks-on builds, and causing the compiler to return an error
3887 code in checks-off builds.
3889 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3891 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
3892 entities of named concurrent types as Ref_Id and not of anonymous
3893 concurrent objects (because callers already know when a conversion
3894 is necessary and can easily do it); also, do not expect protected
3895 types or protected objects as Context_Id (because no flow-related
3896 SPARK pragmas are attached there); reflect these changes in a
3897 more precise comment.

3910 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
3911 for compatibility of component types of formal and actual in an
3912 instantiation of a child unit, when the component type of the
3913 formal is itself a formal of an enclosing generic.
3915 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3917 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
3918 sem_prag.adb to make it available for GNATprove; for concurrent
3919 types replace custom scope climbing with Scope_Same_Or_Within; for
3920 single concurrent objects add scope climbing (with Scope_Within),
3921 which was not there (that's the primary semantic change of this
3922 commit); also, when comparing a single concurrent object with
3923 its corresponding concurrent type rely on equality of types,
3924 not of objects (because that's simpler to code).
3925 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
3926 (Analyze_Global_Item): adjust special-casing of references to the
3927 current instance of a concurrent unit in the Global contracts
3928 of task types and single tasks objects; similar for references
3929 in the protected operations and entries of protected types and
3930 single protected objects (in all these cases the current instance
3931 behaves as an implicit parameter and must not be mentioned in
3932 the Global contract).

3943 name that designates the current instance of a child unit in its
3944 own body and appears as the prefix of a reference to an entity
3945 local to the child unit.
3946 * exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:

4001 of Freeze_Profile, used to inhibit the freezing of the profile
4002 of an expression function declared within a nested package, when

4004 an enclosing package.
4006 2017-09-08 Bob Duff <duff@adacore.com>
4008 * gnat1drv.adb (Gnat1drv): Do not set the Force_ALI_Tree_File flag in
4009 the subunit case. It's still OK to set it in the "missing subunits"
4010 case, because that won't cause the obsolete .ali files that cause
4013 2017-09-08 Bob Duff <duff@adacore.com>
4015 * sinput-l.adb: Remove unused "with Unchecked_Conversion;". It's
4016 unclear why this didn't cause a warning.
4017 * a-uncdea.ads, a-unccon.ads: Add "Ada." to names in the
4018 pragmas. It's unclear why this didn't cause an error.

4054 * exp_disp.adb (Make_DT, Set_All_DT_Position): Handle properly
4055 the placement of a primitive operation O that renames an operation
4056 R declared in an inner package, and which is thus not a primitive
4057 of the dispatching type of O. In this case O is a new primitive
4058 and does not inherit its dispatch table position from R (which

4078 * sem_ch12.adb (Check_Generic_Parent): New procedure within
4079 Analyze_Associations, to handle actual packages that depend on
4080 previous instances. If a package IAP that is an instantiation is
4081 used as an actual in a subsequent instantiation SI in the same
4082 scope, and IAP has a body, IAP must be frozen before SI. If
4083 the generic parent of IAP is itself declared in a previous
4084 instantiation in the same scope, that instantiation must also
4085 be frozen before SI.

4101 initialization code.
4103 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4105 * a-wtdeio.adb (Put, all versions): Use Long_Long_Integer
4106 (Integer_Value (Item)) when the size of the fixed decimal type
4107 is larger than Integer.

4146 * sem_ch6.adb (Analyze_Function_Return): Do not
4147 insert an explicit conversion to force the displacement of the
4148 "this" pointer to reference the secondary dispatch table in the

4187 If the prefix is a reference to an object, rewrite it as an
4188 explicit dereference, as required by 3.7.2 (2) and as is done

4356 is now consulted not only for abstract states and variables,
4357 but for all kinds of items.

4428 types -- just do it for dispatching calls. Misc cleanup.
4429 * sem_util.ads, sem_util.adb (Unqual_Conv): New function to
4430 remove qualifications and type conversions. Fix various bugs
4431 where only a single level of qualification or conversion was
4432 removed, so e.g. "T1'(T2'(X))" would incorrectly return "T2'(X)"
4434 * checks.adb, exp_util.ads, exp_util.adb, sem_res.adb: Misc related
4437 2017-09-07 Ed Schonberg <schonberg@adacore.com>
4439 * sem_ch6.adb (setr_Actual_Subtypes): Within a predicate function
4440 do not create actual subtypes that may generate further predicate
4442 * sem_ch13.adb (Build_Predicate_Functions): Indicate that entity
4443 of body is a predicate function as well.
4444 (Resolve_Aspect_Expressions, Resolve_Name): For a component
4445 association, only the expression needs resolution, not the name.
4446 (Resolve_Aspect_Expressions, case Predicates): Construct and
4447 analyze the predicate function declaration in the scope of the
4448 type, before making the type and its discriminants visible.
4450 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
4452 * gcc-interface/decl.c (warn_on_field_placement): Issue the warning
4453 only if the record type itself comes from source.

4479 2017-09-06 Yannick Moy <moy@adacore.com>
4481 * sem_ch12.adb (Analyze_Instance_And_Renamings): Refactor to set

4484 2017-09-06 Bob Duff <duff@adacore.com>
4486 * sem_ch8.adb: Change Assert to be consistent with
4489 2017-09-06 Bob Duff <duff@adacore.com>
4491 * binde.adb (Find_Elab_Order): Do not run Elab_Old unless
4492 requested. Previously, the -do switch meant "run Elab_New and
4493 Elab_Old and use the order chosen by Elab_Old, possibly with
4494 debugging printouts comparing the two orders." Now it means
4495 "do not run Elab_New." This is of use if there are bugs that
4496 cause Elab_New to crash.
4497 (Elab_Position, Num_Chosen): Change type to Nat, to avoid various
4499 * ali.ads (Elab_Position): Change type to Nat, to avoid various
4502 2017-09-06 Arnaud Charlet <charlet@adacore.com>
4504 * sem_prag.adb (Check_Mode_Restriction_In_Enclosing_Context): Fix
4505 reference to SPARK RM.
4507 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
4509 * layout.adb: Use SSU short hand consistently throughout the file.

4513 * freeze.adb (Freeze_Record_Type)
4514 <Sized_Component_Total_Round_RM_Size>: New local variable to
4515 accumulate the rounded RM_Size of components. Update it for
4516 every component whose RM_Size is statically known. Add missing
4517 guard to check that bit packing is really required before issuing
4518 the error about packing. Swap condition for clarity's sake.
4519 * sem_prag.adb (Usage_Error): Fix reference to SPARK RM in comment.

4538 project manager sources.
4540 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4542 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
4543 entity of a mutable type and the right-hand side is a conditional
4544 expression, resolve the alternatives of the conditional using
4545 the base type of the target entity, because the alternatives
4546 may have distinct subtypes. This is particularly relevant if
4547 the alternatives are aggregates.
4549 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4551 * checks.adb (Apply_Predicate_Check): If the expression is an
4552 aggregate that is the RHS of an assignment, apply the check to
4553 the LHS after the assignment, rather than to the aggregate. This
4554 is more efficient than creating a temporary for the aggregate,
4555 and prevents back-end crashes when the aggregate includes a
4556 dynamic "others' association.
4558 2017-09-06 Yannick Moy <moy@adacore.com>
4560 * sem_ch12.adb (Analyze_Instance_And_Renamings):

4572 * sem_aux.adb (Is_Generic_Formal): Handle properly formal packages.

4576 2017-09-06 Gary Dismukes <dismukes@adacore.com>
4578 * errout.adb (Error_Msg): Separate the
4579 treatment for warning vs. style messages in inlinings and
4580 instantiations. Prevents blowups on calls to Warn_Insertion for
4581 style messages, which should not be called in that case because
4582 Warning_Msg_Char is not set.
4584 2017-09-06 Justin Squirek <squirek@adacore.com>
4586 * sem_prag.adb (Check_VFA_Conflicts): Created
4587 to group all Volatile_Full_Access checks relating to other
4588 representation pragmas (Mark_Component_Or_Object): Created
4589 to centeralize the flagging of attributes for the record type
4590 component case, a pragma applied individually to a component, and
4592 (Process_Atomic_Independent_Shared_Volatile):
4593 Add propagation of certain pragmas to record components and move
4594 evaluation of VFA checks

4607 2017-09-06 Bob Duff <duff@adacore.com>
4609 * sem_ch12.adb (Copy_Generic_Node): When we copy a node
4610 that is a proper body corresponding to a stub, we defer the
4611 adjustment of the sloc until after the correct adjustment has
4612 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
4613 the adjustment, because it will be outside the range in (the old,
4614 incorrect) S_Adjustment.
4615 * inline.adb: Use named notation for readability and uniformity.
4616 * sinput-l.adb: Minor improvements to debugging output printed

4636 Set_Linker_Section_Pragma to be consistant with the "getter"
4637 Linker_Section_Pragma.
4638 * exp_ch5.adb (Expand_Formal_Container_Loop): Add proper error
4639 checking for container loops so that the index cursor is not
4640 directly changable by the user with the use of E_Loop_Parameter.
4641 * sem_ch5.adb (Analyze_Block_Statement): Revert previous change.

4687 the actual is declared in the same unit and has a corresponding
4688 body, to prevent the current instance from being frozen before

4715 (Strip): New routine.
4717 2017-09-06 Bob Duff <duff@adacore.com>
4719 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
4720 we include the proper header. Otherwise, we just declare the necessary
4721 things from the capabilities library. This is so we can build on
4722 machines without that library, while still enabling that library.
4723 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
4724 simply return 0 if the library is not present, or not included

4740 has no parameter specification and no entry index, use the entry name
4741 as the end of the generated SCO statement.
4743 2017-09-06 Steve Baird <baird@adacore.com>
4745 * exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
4746 uses of 'Image and related attributes as having side effects in
4747 order to avoid replicating such uses.
4748 * pprint.ads (Expression_Image) Add new generic formal flag
4749 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
4750 (eventually) override the default.
4751 * pprint.adb (Expression_Image) If the new flag is set, then
4752 suppress the ".all" suffix when displaying a dereference whose
4753 prefix is a use of a value-capturing compiler temp of the sort
4754 generated by Expr_Util.Remove_Side_Effects .

4770 so that applies to any entity.
4772 2017-09-06 Yannick Moy <moy@adacore.com>
4774 * sem_ch3.adb (Derived_Type_Declaration): Use
4775 Incomplete_Or_Partial_View rather than local Find_Partial_View.

4803 * sem_res.adb (Resolve_Arithmentic_Op): If both operands are
4804 Universal_Real and the context is a floating-point type, resolve
4805 both operands to the target type.

4812 2017-09-06 Yannick Moy <moy@adacore.com>
4814 * freeze.adb (Check_Inherited_Conditions): Rewriting
4815 of inherited preconditions and postconditions should only occur
4816 in GNATprove mode, that is, when GNATprove_Mode is True, not to
4817 be confused with SPARK_Mode being On.

4834 (Entity_Table_Size): New constant.
4835 (Entity_Hash): New function.
4836 (Subprogram_Table): New instantiation of GNAT.Htable.Simple_HTable.
4837 (Is_Subprogram_Ref): Rename into...
4838 (Scan_Subprogram_Ref): ...this. Record references to subprograms in
4839 the table instead of bailing out on them. Scan the value of constants
4840 if it is not known at compile time.
4841 (Contains_Subprograms_Refs): Rename into...
4842 (Scan_Subprogram_Refs): ...this.
4843 (Has_Referencer): Scan the body of all inlined subprograms. Reset the
4844 Is_Public flag on subprograms if they are not actually referenced.
4845 (Hide_Public_Entities): Beef up comment on the algorithm.
4846 Reset the table of subprograms on entry.

4934 expression function, or within a spec expression (default value,
4935 etc) a reference to an incomplete type is legal: legality of
4936 the operation will be checked when some related entity (type,
4937 object or subprogram) is frozen.
4939 2017-09-06 Gary Dismukes <dismukes@adacore.com>
4941 * exp_ch5.adb, s-diinio.ads, sem_ch4.adb, s-diflio.ads: Minor spelling

4952 * a-comlin.ads, a-comlin.adb (Argument): Simplify the code, now that
4953 we can use modern Ada in this package.
4954 * s-resfil.ads, s-resfil.adb, a-clrefi.ads, a-clrefi.adb:
4955 Move Ada.Command_Line.Response_File to System.Response_File,
4956 and make Ada.Command_Line.Response_File into a rename of
4957 System.Response_File. This is to avoid having gnatbind depend
4958 Ada.Command_Line, which would damage the bootstrap process now
4959 that Ada.Command_Line contains modern Ada (the raise expression).
4960 * gnatbind.adb: Avoid dependence on
4961 Ada.Command_Line. Depend on System.Response_File instead
4962 of Ada.Command_Line.Response_File. Change one call to
4963 Ada.Command_Line.Command_Name to use Fill_Arg. Change one call
4964 to Ada.Command_Line.Argument_Count to use Arg_Count.
4965 * gcc-interface/Make-lang.in, Makefile.rtl: Take note of the new files.
4967 2017-09-06 Bob Duff <duff@adacore.com>
4969 * frontend.adb (Frontend): Skip -gnatec=gnat.adc

4974 * exp_ch5.adb (Get_Default_Iterator): Replace
4975 "Assert(False)" with "return Iter", because if an iterable

5031 procedure is No_Return.
5032 * sem_ch8.adb (Analyze_Subprogram_Renaming): Implement legality
5033 rule in 6.5.1 (7/2): if a renaming is a completion of a subprogram
5034 with No_Return, the renamed entity must be No_Return as well.
5036 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>
5038 * exp_ch5.adb, freeze.adb, exp_ch4.adb, exp_ch6.adb, lib-xref.adb:

5055 * freeze.adb (Freeze_Entity): Do not generate a freeze
5056 node for a generic unit, even if it includes delayed aspect
5057 specifications. Freeze nodes for generic entities must never
5058 appear in the tree that reaches the back-end of the compiler.

5078 * lib-xref.adb (Get_Through_Renamings): Get through subprogram
5079 renamings; also, avoid repeated calls to Renamed_Object when getting

5082 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5084 * sem_ch3.adb (Array_Type_Declaration): Handle properly an
5085 array type declaration in a private part, when an index is a

5097 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5099 * exp_ch5.adb (Make_Field_Assign): If the type
5100 of the right-hand side has stored constraint, use its values
5101 (except for those that are renamings of parent discriminants)
5102 to produce additional assignments for the discriminants of the
5103 left-hand side, which are invisible in the righ-hand side and
5104 not retrievable as selected components.
5106 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5108 * sem_util.adb (Needs_One_Formal): The first formal of such a
5109 function must be a controlling formal, so that Obj.F (X, Y)
5110 can have the interpretation F(Obj)(X, Y).
5111 * sem_util.ads: Clarify documentation.
5113 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>

5128 * sem_ch12.adb (Analyze_Subprogram_Instantiation): Propagate
5129 No_Return flag to instance if pragma applies to generic unit. This
5130 must be done explicitly because the pragma does not appear
5131 directly in the generic declaration (unlike the corresponding
5132 aspect specification).

5141 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5143 * exp_ch4.adb (Handle_Changed_Representation): For an untagged
5144 derived type with a mixture of renamed and constrained parent
5145 discriminants, the constraint for the target must obtain the
5146 discriminant values from both the operand and from the stored
5147 constraint for it, given that the constrained discriminants are
5148 not visible in the object.
5149 * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
5150 side may be derived from that of the left-hand side (as in the
5151 case of an assignment with a change of representation) so the
5152 discriminant to be used in the retrieval of the value of the
5153 component must be the entity in the type of the right-hand side.
5155 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>

5181 * sem_ch4.adb (Analyze_Set_Membership): If an alternative
5182 in a set membership is an overloaded enumeration literal, and
5183 the type of the alternative is resolved from a previous one,
5184 replace the entity of the alternative as well as the type,
5185 to prevent inconsistencies between the entity and the type.

5729 accessibility entity created for an access parameter, handle
5730 properly a reference to a formal of an enclosing subprogram. if
5731 the reference appears in an inherited class-wide condition, it
5732 is the rewriting of the reference in the ancestor expression,

5773 procedure body for a local (sub)type declaration within a

5780 * exp_util.adb (Insert_Library_Level_Action): Use proper scope

5817 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
5818 Refine predicate for the case where the primitive operation
5819 is a renaming of equality. An overriding operation that is
5820 a user-defined renaming of predefined equality inherits its
5821 slot from the overridden operation. Otherwise it is treated
5822 as a predefined op and occupies the same predefined slot as
5823 equality. A call to it is transformed into a call to its alias,
5824 which is the predefined equality. A dispatching call thus uses
5825 the proper slot if operation is further inherited and called
5826 with class-wide arguments.

5907 * checks.ads (Null_Exclusion_Static_Checks): Add Boolean
5908 parameter Array_Comp to indicate the case of an array object
5909 with null-excluding components.
5910 * checks.adb (Null_Exclusion_Static_Checks):
5911 Call Compile_Time_Constraint_Error instead of
5912 Apply_Compile_Time_Constraint_Error in the component case. Also
5913 call that when Array_Comp is True, with an appropriate warning for
5914 the array component case. Only create an explicit initialization
5915 by null in the case of an object of a null-excluding access type
5916 (and no longer do that in the component case).
5917 * sem_ch3.adb (Check_Component): Add a Boolean parameter
5918 Array_Comp defaulted to False. Pass Empty for the Comp
5919 actual when calling Null_Exclusion_Static_Checks in the case
5920 where Comp_Decl matches Object_Decl, because we don't have a
5921 component in that case. In the case of an object or component
5922 of an array type, pass True for Array_Comp on the recursive call
5925 2017-05-02 Bob Duff <duff@adacore.com>
5927 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
5928 compute the linux priority from the Ada priority. Call this everywhere
5929 required. In particular, the previous version was not doing this
5930 computation when setting the ceiling priority in various places. It
5931 was just converting to C.int, which results in a ceiling that is off
5934 2017-05-02 Ed Schonberg <schonberg@adacore.com>
5936 * sem_ch3.adb: Comment predicate inheritance.
5938 2017-05-02 Tristan Gingold <gingold@adacore.com>
5940 * s-trasym.ads: Add comment.
5942 2017-05-02 Bob Duff <duff@adacore.com>

5946 * s-taprop-linux.adb, s-taspri-posix.ads: Code refactoring.
5947 * s-taspri-posix-noaltstack.ads: Minor refactoring.
5948 * sinput.ads: Minor typo fix.
5950 2017-05-02 Ed Schonberg <schonberg@adacore.com>
5952 * exp_ch9.adb (Discriminated_Size): Moved to sem_util.
5953 * sem_util.ads, sem_util.adb (Discriminated_Size): Predicate moved
5954 here from exp_ch9, to recognize objects whose creation requires
5955 dynamic allocation, so that the proper warning can be emitted
5956 when restriction No_Implicit_Heap_Allocation is in effect.
5957 * sem_ch3.adb (Analyze_Object_Declaration): Use Discriminated_Size
5958 to emit proper warning when an object that requires dynamic
5959 allocation is declared.
5961 2017-05-02 Tristan Gingold <gingold@adacore.com>
5963 * s-trasym.ads, s-trasym.adb (Enable_Cache): New.
5965 2017-05-02 Ed Schonberg <schonberg@adacore.com>
5967 * sem_ch4.adb (Find_Equality_Types, Try_One_Interp): The same relaxed
5968 visibility rules for equality operators that apply within an
5969 instantiation apply within an inlined body.
5970 * sem_type.adb (Add_One_Interp): ditto.
5972 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
5974 * sem_prag.adb (Analyze_Pragma): Forbid pragma Contract_Cases on null
5977 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
5980 (Name_Assume, Name_Attribute_Definition, Name_Loop_Optimize,
5981 Name_No_Tagged_Streams): Move to regular pragmas. Add
5982 placeholders for Default_Scalar_Storage_Order, Dispatching_Domain,
5983 and Secondary_Stack_Size.
5984 (Pragma_Id): Move Pragma_Assume,
5985 Pragma_Attribute_Definition, Pragma_Loop_Optimize and
5986 Pragma_No_Tagged_Streams to second part.
5988 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
5990 * exp_attr.adb: Minor reformatting.
5992 2017-05-02 Ed Schonberg <schonberg@adacore.com>
5994 * sem_ch4.adb (Analyze_Selected_Component): Improve error
5995 detection for illegal references to private components or
5996 operations of a protected type in the body of the type.
5998 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
6000 * opt.ads: Add missing GNAT markers in comments.
6001 * opt.adb (Set_Opt_Config_Switches): Do not override earlier
6002 settings of Optimize_Alignment at the end.
6004 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
6006 * checks.adb (Apply_Constraint_Check): Do not apply
6007 a discriminant check when the associated type is a constrained
6008 subtype created for an unconstrained nominal type.
6009 * exp_attr.adb: Minor reformatting.
6011 2017-05-02 Bob Duff <duff@adacore.com>
6013 * sem_ch3.adb (OK_For_Limited_Init_In_05): Handle correctly
6014 the N_Raise_Expression case.
6015 * sem_ch6.adb (Check_Limited_Return): Minor: clarify comment,
6018 2017-05-02 Yannick Moy <moy@adacore.com>
6020 * exp_ch4.adb (Expand_N_Op_Ne): Do not bump parenthese level and
6021 optimize length comparison in GNATprove mode.
6022 * exp_spark.adb (Expand_SPARK_Op_Ne): New function to rewrite
6023 operator /= into negation of operator = when needed.
6024 (Expand_SPARK): Call new
6025 function to expand operator /=.
6027 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6029 * exp_fixd.adb (Expand_Divide_Fixed_By_Fixed_Giving_Fixed):
6030 Simplify the expression for a fixed-fixed division to remove
6031 divisions by constants whenever possible, as an optimization
6032 for restricted targets.
6034 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
6036 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
6038 2017-05-02 Bob Duff <duff@adacore.com>
6040 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
6041 to find primitive ops, instead of using an Identifier that will
6042 later be looked up. This is necessary because these ops are not
6043 necessarily visible at all places where we need to call them.
6044 * exp_util.ads: Minor comment fix.
6046 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6048 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
6049 references are fully conformant if they are both expansions
6050 of the discriminant of a protected type, within one of the
6051 protected operations. One occurrence may be expanded into a
6052 constant declaration while the other is an input parameter to
6053 the corresponding generated subprogram.
6055 2017-05-02 Justin Squirek <squirek@adacore.com>
6057 * sem_ch3.adb (Check_For_Null_Excluding_Components): Created for
6058 recursivly searching composite-types for null-excluding access
6059 types and verifying them.
6060 (Analyze_Object_Declaration): Add a
6061 call to Check_Null_Excluding_Components for static verification
6062 of non-initialized objects.
6063 * checks.adb, checks.ads (Null_Exclusion_Static_Checks): Added
6064 a parameter for a composite-type's component and an extra case
6065 for printing component information.
6067 2017-05-02 Yannick Moy <moy@adacore.com>
6069 * sem_ch10.adb (Analyze_Subunit): Take
6070 configuration pragma into account when restoring appropriate
6071 pragma for analysis of subunit.
6073 2017-05-02 Justin Squirek <squirek@adacore.com>
6075 * s-tasren.adb, s-tasini.adb, s-taprop-linux.adb,
6076 s-mudido-affinity.adb,, a-exetim-posix.adb, a-direio.adb,
6077 g-socket.adb, s-taenca.adb, s-fileio.adb: Remove unused use-type
6078 clauses from the runtime.
6080 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
6082 * freeze.adb (Check_Component_Storage_Order): Do not treat bit-packed
6083 array components specially.
6085 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6087 * sem_ch8.adb (Premature_Usage): If the premature usage of
6088 an entity is as the expression in its own object decaration,
6089 rewrite the reference as Any_Id to prevent cascaded errors or
6090 compiler loops when such an entity is used in an address clause.
6092 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
6094 * gcc-interface/decl.c (components_to_record): Add missing guard.
6096 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
6098 * gcc-interface/decl.c (components_to_record): Add more comments.
6099 Put back pending fields onto the regular list if the misalignment
6100 happens to cancel itself.
6102 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6104 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
6105 controlling actual in a prefixed call, preserve the original node
6106 information if the prefix itself has been rewritten, for ASIS use.
6108 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6110 * exp_ch6.adb (Insert_Post_Call_Actions):
6111 Code clean up. Insert the post-call actions after an enclosing
6112 procedure call when N denotes a function call and appears as an
6113 actual parameter in the procedure call.
6115 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6117 * freeze.adb (Check_Component_Storage_Order): If there is a clause
6118 for the component, also reject the attribute if the component
6119 doesn't end on a byte boundary and its scalar storage order is
6120 different from that of the enclosing record type.
6122 2017-04-28 Javier Miranda <miranda@adacore.com>
6124 * atree.ads (Info_Messages): Removed.
6125 (Warning_Info_Messages): New counter.
6126 (Report_Info_Messages): New counter.
6127 * err_vars.ads Update documentation.

6138 (Initialize): Update Info_Message occurrences.
6139 * erroutc.adb (Delete_Msg): Update Info_Message occurrences.
6140 (Compilation_Errors): Update Info_Message_Occurences.
6142 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6144 * exp_ch3.adb (Build_Init_Statements): Likewise on Nam.
6145 * freeze.adb (Check_Component_Storage_Order): And on Comp_Byte_Aligned.
6146 * sem_aggr.adb (Resolve_Record_Aggregate): Initialize Box_Node.
6147 * sem_attr.adb (Loop_Entry): Initialize Encl_Loop.
6148 * sem_ch12.adb (Build_Operator_Wrapper): Add pragma Warnings on Expr.

6152 * sem_prag.adb (Analyze_Pragma): Add pragma Warnings on Str.
6154 2017-04-28 Bob Duff <duff@adacore.com>
6156 * sem_util.ads, sem_util.adb (Might_Raise): New function
6157 that replaces Is_Exception_Safe, but has the opposite
6158 sense. Is_Exception_Safe was missing various cases -- calls inside
6159 a pragma Debug, calls inside an 'if' or assignment statement,
6160 etc. Might_Raise now walks the entire subtree looking for things
6162 * exp_ch9.adb (Is_Exception_Safe): Remove.
6163 (Build_Protected_Subprogram_Body): Replace call to
6164 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
6165 constants where possible).
6166 * exp_ch7.adb: Rename Is_Protected_Body -->
6167 Is_Protected_Subp_Body. A protected_body is something different
6170 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6172 * inline.adb (Expand_Inlined_Call): Initialize Targ1 variable.
6173 * par-ch3.adb (P_Component_Items): Initialize Decl_Node variable.

6185 Error_Count (Satisfies_Lock_Free_Requirements): Likewise.
6186 (Analyze_Accept_Statement): Initialize Task_Nam.
6188 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6190 * checks.adb (Install_Primitive_Elaboration_Check):
6191 Do not generate an elaboration check if all checks have been
6194 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6196 * sem_ch13.adb (Analyze_Aspect_Specifications, case
6197 Interrupt_Handler and Attach_Handler): Generate reference
6198 to protected operation to prevent spurious warnings about
6199 unreferenced entities. Previous scheme failed with style checks
6202 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6204 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
6205 that follows an expression function must not be relocated to
6206 the generated body, because it applies to the code that follows.
6208 2017-04-28 Gary Dismukes <dismukes@adacore.com>
6210 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
6211 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
6212 code that might violate the more stringent checking for 'Access
6213 introduced in Ada 2005.
6215 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6217 * a-cforse.adb: minor style fix in comment.
6219 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6221 * exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also
6222 initialize Block_Decls variable.
6223 (Expand_Entry_Barrier): Add pragma Warnings on Func_Body variable.
6224 (Build_Dispatching_Requeue): Add pragma Warnings on Op variable.
6225 * exp_disp.adb (Expand_Interface_Actuals): Initialize
6226 Formal_DDT and Actual_DDT variables.
6227 (Expand_Interface_Thunk): Initialize Iface_Formal.
6228 (Make_DT): Initialize Size_Comp.
6229 (Make_Select_Specific_Data_Table): Initialize Decls.
6230 * exp_dist.adb (Add_RACW_Primitive_Declarations_And_Bodies):
6231 Also initialize more RPC_Receiver_* variables.
6232 (Build_To_Any_Function): Initialize Cstr_Formal.
6233 * exp_prag.adb (Expand_Pragma_Contract_Cases): Initialize Msg_Str.
6235 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6237 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
6238 node between access types, freeze the designated type as well,
6239 so that dispatch table pointers are created in the proper scope,
6240 and not in the constructed body of the expression function.
6242 2017-04-28 Bob Duff <duff@adacore.com>
6244 * alloc.ads (Nodes_Initial): Go back to previous value. The large
6245 value makes large compilations faster, but small compilations slower.
6247 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6249 * sem_util.adb: minor typos in Is_Child_Or_Sibling.
6251 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6253 * erroutc.adb (Compilation_Errors): Do not consider info messages
6254 as suitable warnings when warnings must be treated as errors.
6255 * sem_ch7.adb (Analyze_Package_Specification): Do not consider
6256 internally-generated packages when outputting completion
6258 * errout.adb (Output_Messages): Do not consider info messages as
6259 suitable warnings when warnings must be treated as errors.
6260 * errutil.adb (Finalize): Do not consider info messages as
6261 suitable warnings when warnings must be treated as errors.
6263 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6265 * warnsw.ads: Minor fix for incorrect wording in comment.
6267 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6269 * sem_res.adb (In_Instance_Code): New predicate in
6270 Valid_Conversion, to determine whether a type conversion appears
6271 as (or within) an actual for a formal object. Type conversions
6272 in instances are not rechecked in Valid_Conversion because
6273 visibility changes between generic location andi instance may
6274 lead to spurious errors, but conversions within an actual must be
6275 fully checked, and they are not fully resolved when pre-analyzing
6278 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6280 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
6281 New_Copy_Tree instead of Relocate_Node as any subsequent copies
6282 of the relocated node will have mangled Parent pointers.
6283 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
6284 tables used in conjunction with entity and itype replication.
6285 (Visit_Entity): Rewrite the restriction on which entities
6286 require duplication. The restriction now includes all types.
6288 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6290 * a-cofuse.ads, a-cfdlli.ads, a-cfhase.adb, a-cfhase.ads, a-cfinve.adb,

6300 2017-04-28 Gary Dismukes <dismukes@adacore.com>
6302 * exp_util.adb: Minor reformatting.
6304 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6306 * sem_ch4.adb: Fix copy/pasto.
6308 2017-04-27 Tristan Gingold <gingold@adacore.com>
6310 * gcc-interface/Make-lang.in: Define EH_MECHANISM while building
6311 raise-gcc.c. Fix include search path for raise-gcc.c
6313 2017-04-27 Eric Botcazou <ebotcazou@adacore.com>
6315 * fe.h (Warn_On_Questionable_Layout): Declare.
6316 * warnsw.ads (Warn_On_Record_Holes): Move down.
6317 (Warn_On_Questionable_Layout): New boolean variable.
6318 (Warning_Record): Add Warn_On_Questionable_Layout field.
6319 * warnsw.adb (All_Warnings): Set Warn_On_Questionable_Layout.
6320 (Restore_Warnings): Likewise.
6321 (Save_Warnings): Likewise.
6322 (Set_Dot_Warning_Switch): Handle 'q' and 'Q' letters.
6323 * gcc-interface/decl.c (gnat_to_gnu_entity): Adjust call to
6324 components_to_record.
6325 (gnu_field_to_gnat): New function.
6326 (warn_on_field_placement): Likewise.
6327 (components_to_record): Add GNAT_RECORD_TYPE and remove REORDER
6328 parameters. Rename local variables and adjust recursive call.
6329 Rework final scan of the field list and implement warnings on the
6330 problematic placement of specific sorts of fields.
6332 2017-04-27 Bob Duff <duff@adacore.com>
6334 * errout.adb, exp_aggr.adb, exp_attr.adb, exp_code.adb, fname.adb,
6335 * fname.ads, freeze.adb, inline.adb, lib.adb, lib.ads, lib-list.adb,
6336 * lib-load.adb, lib-writ.adb, par.adb, restrict.adb, rtsfind.adb,

6338 * sem_ch4.adb, sem_ch6.adb, sem_ch8.adb, sem_ch9.adb, sem_elab.adb,
6339 * sem_intr.adb, sem_res.adb, sem_util.adb, sem_warn.adb, sprint.adb:
6340 For efficiency, cache results of Is_Internal_File_Name and
6341 Is_Predefined_File_Name in the Units table. This avoids a lot
6342 of repeated text processing.
6344 2017-04-27 Emmanuel Briot <briot@adacore.com>
6346 * g-comlin.adb (Sort_Sections): remove useless test.
6348 2017-04-27 Claire Dross <dross@adacore.com>
6350 * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
6351 allow the use of regular equality over elements in contracts.
6352 (Formal_Model): Ghost package containing model functions that are
6353 used in subprogram contracts.
6354 (Current_To_Last): Removed, model functions should be used instead.
6355 (First_To_Previous): Removed, model functions should be used instead.
6356 (Strict_Equal): Removed, model functions should be used instead.
6357 (No_Overlap): Removed, model functions should be used instead.
6358 (Equivalent_Keys): Functions over cursors are removed. They were
6359 awkward with explicit container parameters.
6360 * a-cforse.adb, a-cforse.ads (=): Generic parameter removed to
6361 allow the use of regular equality over elements in contracts.
6362 (Formal_Model): Ghost package containing model functions that
6363 are used in subprogram contracts.
6364 (Current_To_Last): Removed, model functions should be used instead.
6365 (First_To_Previous): Removed, model functions should be used instead.
6366 (Strict_Equal): Removed, model functions should be used instead.
6367 (No_Overlap): Removed, model functions should be used instead.
6369 2017-04-27 Yannick Moy <moy@adacore.com>
6371 * gnat1drv.adb: Code cleanup.
6373 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6375 * exp_util.adb (Replace_Entity): The prefix of a 'Result
6376 attribute reference in a post- condition is the subprogram to
6377 which the condition applies. If the condition is inherited
6378 by a type extension, the prefix becomes a reference to the
6379 inherited operation, but there is no need to create a wrapper
6380 for this operation, because 'Result is expanded independently
6381 when elaborating the postconditions.
6383 2017-04-27 Bob Duff <duff@adacore.com>
6385 * sinput.adb: Minor code cleanup.
6386 * namet.adb (Append): Create faster versions of
6387 Append(String) and Append(Name_Id) by using slice assignment
6389 * sem_util.adb (In_Instance): Speed this up by removing
6390 unnecessary tests; Is_Generic_Instance is defined for all
6392 * sem_util.ads, sem_util.adb (In_Parameter_Specification):
6393 Remove unused function.
6394 * alloc.ads (Nodes_Initial): Use a much larger value, because
6395 the compiler was spending a lot of time copying the nodes table
6396 when it grows. This number was chosen in 1996, so is rather out
6397 of date with current memory sizes. Anyway, it's virtual memory.
6398 Get rid of Orig_Nodes_...; use Node_... instead.
6399 * atree.adb (Lock): Do not release the Nodes tables; it's a
6401 Orig_Nodes_ ==> Nodes_

6919 perform check if the current scope does not come from source,
6920 as is the case for a rewritten task body, because check has
6921 been performed already, and may not be doable because of changed

6934 replace the type of the call by the full view, to prevent spurious
6936 * exp_disp.adb (Check_Premature_Freezing): Disable check on an
6937 abstract subprogram so that compiler does not reject a parameter
6938 of a primitive operation of a tagged type being frozen, when
6939 the untagged type of that parameter cannot be frozen.

6977 modifications in functional containers.
6978 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
6979 to improve readablity. Subprograms are separated between basic
6980 operations, constructors and properties. Universally quantified
6981 formulas in contracts are factorized in independant functions
6982 with a name and a comment. Names of parameters are improved.

6995 not install a predicate check if the object is initialized by
6996 means of a type conversion because the conversion is subjected

7072 * exp_ch7.adb (Establish_Transient_Scope): Rewrite
7073 the loop which detects potential enclosing transient scopes. The
7074 loop now terminates much earlier as transient scopes are bounded
7075 by packages and subprograms.
7077 2017-04-27 Claire Dross <dross@adacore.com>
7079 * a-cfdlli.adb, a-cfdlli.ads (=): Generic parameter removed to

7134 * debug.adb Change the documentation of switch -gnatd.s.
7135 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
7136 to manage the secondary stack when an enclosing scope already
7137 performs this functionality (aka relaxed management). Switch
7138 -gnatd.s may be used to force strict management in which case
7139 the block will manage the secondary stack unconditionally. Add
7140 a guard to stop the traversal when encountering a package or a
7143 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7145 * sem_res.adb (Resolve_Call): Refine further the handling of
7146 limited views of return types in function calls. If the function
7147 that returns a limited view appears in the current unit,
7148 we do not replace its type by the non-limited view because
7149 this transformation is performed int the back-end. However,
7150 the type of the call itself must be the non-limited view, to
7151 prevent spurious resolution errors.
7153 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7155 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
7156 Removed, proposed implementation using generics for class-wide
7157 preconditions proved impractical.
7158 (Class_Wide_Clone): New attribute of subprogram. Designates
7159 subprogram created for primitive operations with class-wide
7160 pre/postconditions that contain calls to other primitives. The
7161 clone holds the body of the original primitive, but the
7162 pre/postonditions do not apply to it. The original body is
7163 rewritten as a wrapper for a call to the clone.
7164 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
7165 the flag is set, no code for the corresponding pre/postconditions
7166 is inserted into its body.
7168 2017-04-27 Bob Duff <duff@adacore.com>
7170 * exp_prag.adb, par-prag.adb, sem_ch13.adb: Ignore

7214 private child of Ada.Containers used to implement all functional
7216 * a-cofuma.ads, a-cofuma.adb (Ada.Containers.Functional_Maps): New
7217 child of Ada.Containers. It provides functional indefinite unbounded
7218 maps which can be used as high level models for specification
7220 * a-cofuse.ads, a-cofuse.adb (Ada.Containers.Functional_Sets): New
7221 child of Ada.Containers. It provides functional indefinite unbounded
7222 sets which can be used as high level models for specification
7224 * a-cofuve.ads, a-cofuve.adb (Ada.Containers.Functional_Vectors): New
7225 child of Ada.Containers. It provides functional indefinite unbounded
7226 vectors which can be used as high level models for specification

7235 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7237 * sem_ch12.adb (Analyze_Associations): minor reformatting.
7238 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed
7239 point type actual that has user-defined arithmetic primitives,
7240 when there is a previous actual for a formal package that defines
7241 a fixed-point type with the parent user-defined operator.
7243 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7245 * checks.adb (Generate_Range_Check): Reinstate part of previous change.
7246 * sem_attr.adb (Resolve_Attribute): Generate a range check when
7247 the component type allows range checks.
7249 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7251 * sem_aux.adb (Is_Generic_Formal): Use original node to locate
7252 corresponding declaration, because formal derived types are
7253 rewritten as private extensions.
7255 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7257 * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check
7258 dimensions of operands if node has been analyzed already, because
7259 previous analysis and dimension checking will have removed the
7260 dimension information from the operands.
7262 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7264 * debug.adb: Document the use of switch -gnatd.s.
7265 * einfo.ads Update the documentation on attribute
7266 Sec_Stack_Needed_For_Return and attribute Uses_Sec_Stack. Remove
7267 the uses of these attributes from certain entities.

7269 which determines whether the block should continue to manage
7270 the secondary stack.

7324 of silently ignoring pragma Ada_xxx in Latest_Ada_Only mode.
7325 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Use
7326 Ada_2012 instead of Ada_2005 to be compatible with the above
7328 * bindgen.adb: Silence new warning on pragma Ada_95.
7330 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

7347 * types.ads, osint.adb, sinput-c.adb, sinput-d.adb, sinput-l.adb,
7348 * sinput-p.adb: Use regular fat pointers, with bounds checking,
7349 for source buffers. Fix misc obscure bugs.
7350 * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
7351 checking, for source buffers. Modify representation clause for
7352 Source_File_Record as appropriate. Move Source_File_Index_Table
7353 from spec to body, because it is not used outside the body.
7354 Move Set_Source_File_Index_Table into the private part, because
7355 it is used only in the body and in children. Use trickery to
7356 modify the dope in the generic instantiation case. It's ugly,
7357 but not as ugly as the previous method. Fix documentation.
7358 Remove obsolete code.

7374 expander is not active or when index/range checks are suppressed
7376 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
7377 Remove variants that include a Supress parameter. These routines
7378 are never used, and were introduced before the current scope-based
7379 check suppression method.

7925 * exp_ch3.adb (Freeze_Type): Add condition to always treat
7926 interface types as a partial view of a private type for the
7927 generation of invariant procedure bodies.
7928 * exp_util.adb, exp_util.ads (Add_Inherited_Invariants):
7929 Add a condition to get the Corresponding_Record_Type for
7930 concurrent types, add condition to return in the absence of a
7931 class in the pragma, remove call to Replace_Type_References,
7932 and add call to Replace_References.
7933 (Add_Interface_Invariatns),
7934 (Add_Parent_Invariants): Modify call to Add_Inherited_Invariants
7935 to including the working type T.
7936 (Add_Own_Invariants): Remove
7937 legacy condition for separate units, remove dispatching for ASIS
7938 and save a copy of the expression in the pragma expression.
7939 (Build_Invariant_Procedure_Body): Default initalize vars,
7940 remove return condition on interfaces, always use the
7941 private type for interfaces, and move the processing of types
7942 until after the processing of invariants for the full view.
7943 (Build_Invariant_Procedure_Declaration): Remove condition
7944 to return if an interface type is encountered and add
7945 condition to convert the formal parameter to its class-wide
7946 counterpart if Work_Typ is abstract.
7947 (Replace_Type): Add call to Remove_Controlling_Arguments.
7948 (Replace_Type_Ref): Remove class-wide dispatching for the current
7949 instance of the type.
7950 (Replace_Type_References): Remove parameter "Derived"
7951 (Remove_Controlling_Arguments): Created in order to removing
7952 the controlliong argument from calls to primitives in the case
7953 of the formal parameter being an class-wide abstract type.
7954 * sem_ch3.adb (Build_Assertion_Bodies_For_Type): Almost identical
7955 to the change made to Freeze_Type in exp_ch3. Add a condition
7956 to treat interface types as a partial view.
7957 * sem_prag.adb (Analyze_Pragma): Modify parameters in the call
7958 to Build_Invariant_Procedure_Declaration to properly generate a
7959 "partial" invariant procedure when Typ is an interface.
7961 2017-04-25 Bob Duff <duff@adacore.com>
7963 * a-numeri.ads: Go back to using brackets encoding for the Greek
7966 2017-04-25 Ed Schonberg <schonberg@adacore.com>
7968 * sem_ch3.adb (Derive_Subprogram): Implement rule in RM 6.1.1
7969 (10-15): if derived type T with progenitors is abstract,
7970 and primitive P of this type inherits non-trivial classwide
7971 preconditions from both a parent operation and from an interface
7972 operation, then the inherited operation is abstract if the parent
7973 operation is not null.
7974 * sem_disp.ads, sem_disp.adb: replace function Covers_Some_Interface
7975 with Covered_Interface_Op to yield the actual interface operation
7976 that is implemented by a given inherited operation.
7978 2017-04-25 Javier Miranda <miranda@adacore.com>
7980 * exp_ch4.adb (Expand_N_Op_Expon): Relocate left
7981 and right operands after performing the validity checks. Required
7982 because validity checks may remove side effects from the operands.
7984 2017-04-25 Javier Miranda <miranda@adacore.com>
7986 * exp_attr.adb (Attribute_Unrestricted_Access):
7987 Do not disable implicit type conversion. Required to generate
7988 code that displaces the pointer to reference the secondary
7991 2017-04-25 Pascal Obry <obry@adacore.com>
7993 * prj-attr.adb, snames.ads-tmpl: Add package Install's
7994 Required_Artifacts attribute.
7996 2017-04-25 Ed Schonberg <schonberg@adacore.com>
7998 * sem_util.adb (Same_Value): String literals are compile-time
7999 values, and comparing them must use Expr_Value_S.
8001 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8003 * sem_ch4.adb (Complete_Object_Interpretation): If an explicit
8004 dereference is introduced for the object, and the object is
8005 overloaded, do not check whether it is aliased, because it may
8006 include an implicit dereference.
8007 * sem_type.adb (Disambiguate): If two interpretations are access
8008 attribute types with the same designated type keep either of
8009 them and do not report an ambiguity. A true ambiguity will be
8012 2017-04-25 Bob Duff <duff@adacore.com>
8014 * a-numeri.ads: Change the encoding of Greek letter Pi from
8015 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
8016 to indicate the encoding. We considered using a byte order mark
8017 (BOM), but that causes various trouble (misc software eats the
8018 BOM, if you have a patch with a BOM, then it's not at the start
8019 of the patch, so it's not a BOM, the BOM affects with-ing files,
8021 * scng.adb, s-wchcnv.adb: Minor.

8033 moved here from sem_ch3.
8034 * sem_ch8.adb (Analyze_Subprogram_Renaming): Implement legality
8035 check given in RM 6.1.1 (17) concerning renamings of overriding
8036 operations that inherits class-wide preconditions from ancestor
8039 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

8057 restrictions when the handler is internally generated and the
8060 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8062 * sem_ch3.adb (Has_Non_Trivial_Precondition): New predicate to
8063 enforce legality rule on classwide preconditions inherited from
8064 both an ancestor and a progenitor (RM 6.1.1 (10-13).
8065 * sem_disp.adb (Check_Dispatching_Context): A call to an abstract
8066 subprogram need not be dispatching if it appears in a precondition
8067 for an abstract or null subprogram.
8069 2017-04-25 Gary Dismukes <dismukes@adacore.com>
8071 * sem_ch10.adb: Minor typo fix.
8073 2017-04-25 Arnaud Charlet <charlet@adacore.com>
8075 * gcc-interface/Makefile.in: Cleanup VxWorks targets.
8077 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8079 * fname.adb (Is_Internal_File_Name): Arrange for the slices to
8080 have a length which is a power of 2.
8081 (Is_Predefined_File_Name): Likewise. Adjust comment.
8083 2017-04-25 Bob Duff <duff@adacore.com>
8085 * exp_aggr.adb (Component_Count): Protect the
8086 arithmetic from attempting to convert a value >= 2**31 to Int,
8087 which would otherwise raise Constraint_Error.
8089 2017-04-25 Bob Duff <duff@adacore.com>
8091 * opt.ads (Locking_Policy): Fix incorrect documentation. The
8092 first character of the policy name is not unique.
8094 2017-04-25 Bob Duff <duff@adacore.com>
8096 * s-fileio.adb (Name): Raise Use_Error if the file is a temp file.
8097 * s-ficobl.ads (Is_Temporary_File): Remove incorrect comment
8098 about this flag not being used. It was already used, and it is

8115 Save and restore the value of global flag
8116 Ignore_SPARK_Mode_Pragmas_In_Instance. Set or reinstate the value
8117 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance when either
8118 the corresponding spec or the body must ignore all SPARK_Mode
8119 pragmas found within.
8120 (Analyze_Subprogram_Declaration): Mark
8121 the spec when it needs to ignore all SPARK_Mode pragmas found
8122 within to allow the body to infer this property in case it is
8123 instantiated or inlined later.
8124 * sem_ch7.adb (Analyze_Package_Body_Helper): Save and restore the
8125 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
8126 the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
8127 when the corresponding spec also ignored all SPARK_Mode pragmas
8129 (Analyze_Package_Declaration): Mark the spec when
8130 it needs to ignore all SPARK_Mode pragmas found within to allow
8131 the body to infer this property in case it is instantiated or
8133 * sem_ch12.adb (Analyze_Formal_Package_Declaration):
8134 Save and restore the value of flag
8135 Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
8136 formal spec when it needs to ignore all SPARK_Mode
8137 pragmas found within to allow the body to infer this
8138 property in case it is instantiated or inlined later.
8139 (Analyze_Package_Instantiation): Save and restore the value
8140 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark
8141 the instance spec when it needs to ignore all SPARK_Mode
8142 pragmas found within to allow the body to infer this

8145 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
8146 instance spec and anonymous package when they need to ignore
8147 all SPARK_Mode pragmas found within to allow the body to infer

8160 Ignore_Pragma_SPARK_Mode.
8161 * sem_util.adb (SPARK_Mode_Is_Off): A construct which ignored
8162 all SPARK_Mode pragmas defined within yields mode "off".
8164 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8166 * bindgen.adb, exp_dbug.adb, errout.adb, fname.adb: Minor reformatting.
8168 2017-04-25 Bob Duff <duff@adacore.com>
8170 * exp_atag.adb (Build_CW_Membership): Add "Suppress =>
8171 All_Checks" to avoid generating unnecessary checks.

8179 2017-04-25 Gary Dismukes <dismukes@adacore.com>
8181 * s-taprop-linux.adb: Minor editorial fixes.
8183 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8185 * sem_util.adb (New_Copy_Tree): Put back the declarations of the
8186 hash tables at library level. Reinstate the NCT_Hash_Tables_Used
8187 variable and set it to True whenever the main hash table is
8188 populated. Short- circuit the Assoc function if it is false
8189 and add associated guards.
8191 2017-04-25 Olivier Hainque <hainque@adacore.com>
8193 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
8194 specs without elaboration code that have an elaboration counter
8195 nevertheless, e.g. when compiled with -fpreserve-control-flow.
8196 * sem_ch10.adb (Analyze_Compilation_Unit):
8197 Set_Elaboration_Entity_Required when requested to preserve
8198 control flow, to ensure the unit elaboration is materialized at
8199 bind time, resulting in the inclusion of the unit object file
8200 in the executable closure at link time.
8202 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
8204 * exp_dbug.adb: In Debug_Renaming_Declaration,
8205 when dealing with indexed component, accept to produce a renaming
8206 symbol when the index is an IN parameter or when it is a name
8207 defined in an outer scope.
8209 2017-04-25 Yannick Moy <moy@adacore.com>
8211 * errout.adb (Error_Msg): Adapt continuation
8212 message in instantiations and inlined bodies for info messages.
8214 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8216 * fname.adb (Has_Internal_Extension): Add pragma Inline.
8217 Use direct 4-character slice comparisons.
8219 pragma Inline. (Has_Suffix): Delete.
8220 (Is_Internal_File_Name):
8221 Test Is_Predefined_File_Name first.
8222 (Is_Predefined_File_Name):

8226 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8228 * checks.adb (Insert_Valid_Check): Code cleanup.
8229 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
8230 (Expand_Actuals): Generate proper copy-back for a validation
8231 variable when it acts as the argument of a type conversion.
8232 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
8233 predicate to operate on type qualifications.
8235 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8237 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
8240 2017-04-25 Bob Duff <duff@adacore.com>
8242 * sem_prag.adb (No_Return): Give an error if the pragma applies
8243 to a body. Specialize the error for the specless body case,
8244 as is done for (e.g.) pragma Convention.
8245 * debug.adb: Add switch -gnatd.J to disable the above legality
8246 checks. This is mainly for use in our test suite, to avoid
8247 rewriting a lot of illegal (but working) code. It might also
8248 be useful to customers. Under this switch, if a pragma No_Return
8249 applies to a body, and the procedure raises an exception (as it
8250 should), the pragma has no effect. If the procedure does return,
8251 execution is erroneous.
8253 2017-04-25 Bob Duff <duff@adacore.com>
8255 * exp_ch6.adb (Expand_Actuals): This is the
8256 root of the problem. It took N as an 'in out' parameter, and in
8257 some cases, rewrote N, but then set N to Original_Node(N). So
8258 the node returned in N had no Parent. The caller continued
8259 processing of this orphaned node. In some cases that caused a
8260 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
8261 and trips over the Empty Parent). The solution is to make N an
8262 'in' parameter. Instead of rewriting it, return the list of
8263 post-call actions, so the caller can do the rewriting later,
8264 after N has been fully processed.
8265 (Expand_Call_Helper): Move most of Expand_Call here. It has
8266 too many premature 'return' statements, and we want to do the
8267 rewriting on return.
8268 (Insert_Post_Call_Actions): New procedure to insert the post-call
8269 actions in the appropriate place. In the problematic case,
8270 that involves rewriting N as an Expression_With_Actions.
8271 (Expand_Call): Call the new procedures Expand_Call_Helper and
8272 Insert_Post_Call_Actions.
8274 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8276 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
8277 properly type derived from generic formal types, to handle
8278 properly modified version of ACATS 4.1B B611017.
8280 2017-04-25 Javier Miranda <miranda@adacore.com>
8282 * exp_unst.adb (Subp_Index): Adding missing
8283 support for renamings and functions that return a constrained
8284 array type (i.e. functions for which the frontend built a
8285 procedure with an extra out parameter).
8287 2017-04-25 Pascal Obry <obry@adacore.com>
8289 * s-string.adb: Minor code clean-up.
8291 2017-04-25 Bob Duff <duff@adacore.com>

8296 function for Non_Blocking_Wait_Process.
8298 2017-04-25 Bob Duff <duff@adacore.com>
8300 * prep.adb (Preprocess): Remove incorrect
8301 Assert. Current character can be ASCII.CR.
8303 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8305 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
8306 convention Stdcall, which has a number of exceptions. Convention
8307 is legal on a component declaration whose type is an anonymous
8308 access to subprogram.
8310 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8312 * sem_ch4.adb: sem_ch4.adb Various reformattings.
8313 (Try_One_Prefix_Interpretation): Use the base type when dealing
8314 with a subtype created for purposes of constraining a private
8315 type with discriminants.
8317 2017-04-25 Javier Miranda <miranda@adacore.com>
8319 * einfo.ads, einfo.adb (Has_Private_Extension): new attribute.
8320 * warnsw.ads, warnsw.adb (All_Warnings): Set warning on late
8321 dispatching primitives (Restore_Warnings): Restore warning on
8322 late dispatching primitives (Save_Warnings): Save warning on late
8323 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
8324 to enable/disable this warning.
8325 (WA_Warnings): Set warning on late dispatching primitives.
8326 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
8327 that its parent type has a private extension.
8328 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
8330 * usage.adb: Document -gnatw.j and -gnatw.J.
8332 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8334 * exp_ch7.adb, checks.adb, sem_prag.adb, eval_fat.adb: Minor
8337 2017-04-25 Bob Duff <duff@adacore.com>
8339 * binde.adb (Validate): Do not pass dynamic strings
8340 to pragma Assert, because older compilers do not support that.
8342 2017-04-25 Bob Duff <duff@adacore.com>
8344 * s-fileio.adb (Close): When a temp file is
8345 closed, delete it and clean up its Temp_File_Record immediately,
8346 rather than waiting until later.
8347 (Temp_File_Record): Add File
8348 component, so Close can know which Temp_File_Record corresponds
8349 to the file being closed.
8350 (Delete): Don't delete temp files,
8351 because they are deleted by Close.
8352 (Open): Set the File component
8353 of Temp_File_Record. This requires moving the creation of the
8354 Temp_File_Record to the end, after the AFCB has been created.
8356 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8358 * checks.adb (Insert_Valid_Check): Do not generate
8359 a validity check when inside a generic.

8372 * sem_prag.adb (Analyze_Pre_Post_Condition): The rules
8373 concerning inheritance of class-wide preconditions do not apply
8376 2017-04-25 Bob Duff <duff@adacore.com>
8378 * s-ficobl.ads: Minor comment fix.
8380 2017-04-25 Yannick Moy <moy@adacore.com>
8382 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
8383 conversions from float to integer in GNATprove mode.
8384 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
8385 to call Apply_Type_Conversion_Checks, so that range checks
8386 are properly positioned when needed on conversions, including
8387 when converting from float to integer. (Determine_Range): In
8388 GNATprove mode, take into account the possibility of conversion
8389 from float to integer.
8390 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
8391 check on conversions from fixed-point to integer, not anymore
8392 on conversions from floating-point to integer, when in GNATprove
8395 2017-04-25 Yannick Moy <moy@adacore.com>
8397 * checks.adb (Determine_Range_R): Special case type conversions
8398 from integer to float in order to get bounds in that case too.

8434 Pre'Class aspect is specified for the corresponding primitive
8435 subprogram of some ancestor of T.
8437 2017-04-25 Bob Duff <duff@adacore.com>
8439 * sem_ch8.adb (Use_One_Type): If a use_type_clause
8440 is redundant, set its Used_Operations to empty. This is only
8441 necessary for use clauses that appear in the parent of a generic
8442 child unit, because those use clauses get reanalyzed when we
8443 instantiate the generic, and we don't want the Used_Operations
8444 carried over from the original context (where it was probably

8457 * par.adb (Par): Null out Current_Source_File, to ensure that
8458 the above bugs won't rear their ugly heads again.
8460 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8462 * sem_ch8.adb (Find_Type): For an attribute reference
8463 'Class, if prefix type is synchronized and previous errors
8464 have suppressed the creation of the corresponding record type,
8465 create a spurious class-wide for the synchonized type itself,
8466 to catch other misuses of the attribute
8468 2017-04-25 Steve Baird <baird@adacore.com>
8470 * exp_ch6.adb (Expand_Simple_Function_Return): if CodePeer_Mode
8471 is True, then don't generate the accessibility check for the
8472 tag of a tagged result.

8474 if CodePeer_Mode is True, then don't generate the
8475 tag checks for the result of call to an instance of
8476 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
8477 descendant of" check and the accessibility check).
8479 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8481 * sem_ch13.adb: Code cleanups.
8482 * a-strbou.ads: minor whitespace fix in Trim for bounded strings.

8487 * exp_ch4.adb (Library_Level_Target): New function.
8488 (Expand_Concatenate): When optimization is enabled, also expand
8489 the operation out-of-line if the concatenation is present within
8490 the expression of the declaration of a library-level object and
8491 not only if it is the expression of the declaration.
8493 2017-04-25 Bob Duff <duff@adacore.com>
8495 * freeze.adb (Freeze_Object_Declaration): Do
8496 not Remove_Side_Effects if there is a pragma Linker_Section,
8497 because in that case we want static initialization in the
8498 appropriate section.
8500 2017-04-25 Gary Dismukes <dismukes@adacore.com>
8502 * exp_dbug.adb: Minor rewording and reformatting.
8504 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8506 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
8507 handle the proposed changes to rules concerning potentially
8508 unevaluated expressions, to include selected components that
8509 do not depend on discriminants, and indexed components with
8511 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
8512 predicate in quantified expression, and fix bugs in the handling
8513 of case expressions and membership test.
8514 (Analyze_Attribute_Old_Result): use new predicate.

8531 renaming entity for debug information, mark the entity as needing debug
8532 info if it comes from sources.
8534 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8536 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Remove the
8537 restriction converning the use of 'Address where the prefix is

8551 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8553 * sem_ch3.adb (Check_Entry_Contract): Call
8554 Preanalyze_Spec_Expression so that resolution takes place as well.
8555 * sem_util.adb (Check_Internal_Protected_Use): Reject properly
8556 internal calls that appear in preconditions of protected
8557 operations, in default values for same, and in contract guards
8558 for contract cases in SPARK.
8560 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8562 * a-numaux.ads: Fix description of a-numaux-darwin
8564 (Double): Define to Long_Float.

8566 * a-numaux-darwin.ads
8568 * a-numaux-libc-x86.ads (Double): Define to Long_Long_Float.
8569 * a-numaux-x86.ads: Fix package description.
8570 * a-numaux-x86.adb (Is_Nan): Minor tweak.
8571 (Reduce): Adjust and complete description. Call Is_Nan instead of
8572 testing manually. Use an integer temporary to hold rounded value.
8573 * a-numaux-darwin.adb (Reduce): Likewise.
8574 (Is_Nan): New function.
8576 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8578 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
8579 on analysis of prefix whose type is a current instance of a
8580 synchronized type, but where the prefix itself is an entity that
8583 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8585 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
8586 the identity of callable entities therein, because they have been
8587 properly resolved, and prefixed calls may have been rewritten
8590 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
8592 * exp_ch3.adb (Build_Init_Statements): Convert
8593 the expression of the pragma/aspect Secondary_Stack_Size to

8606 * s-osinte-freebsd.ads: Minor comment tweaks
8608 2017-04-25 Javier Miranda <miranda@adacore.com>
8610 * urealp.adb (UR_Write): Reverse previous patch
8611 adding documentation on why we generate multiplications instead
8612 of divisions (needed to avoid expressions whose computation with
8613 large numbers may cause division by 0).
8615 2017-04-25 Bob Duff <duff@adacore.com>
8617 * erroutc.adb (Set_Specific_Warning_Off,
8618 Set_Warnings_Mode_Off): Use the correct source file for
8619 Stop. Was using Current_Source_File, which is only valid during
8620 parsing. Current_Source_File will have a leftover value from
8621 whatever file happened to be parsed last, because of a with_clause
8624 2017-04-25 Bob Duff <duff@adacore.com>
8626 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
8627 to In_Predefined_Unit, but including GNAT units.
8628 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
8629 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
8630 because Should_Ignore_Pragma was not working reliably outside
8631 the parser, because Current_Source_File is not valid.
8632 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
8633 * par-prag.adb: Call Should_Ignore_Pragma_Par.

8670 Build_Invariant_Procedure_Body.
8671 (Build_Invariant_Procedure_Body):
8672 Remove refactored calls and integrated code from
8673 Add_Parent_Invariants and Add_Interface_Invariants.
8675 2017-04-25 Johannes Kanig <kanig@adacore.com>
8677 * errout.adb (Output_Messages): Adjust computation of total
8679 * erroutc.adb (Error_Msg): In statistics counts, deal
8680 correctly with informational messages that are not warnings.

8697 (Uses_Unseen_Lib_Unit_Priv): Predicate function made from extracted
8700 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8702 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
8703 of prefix whose type is a current instance of a synchronized
8704 type. If the prefix is an object this is an external call (or
8705 requeue) that can only access public operations of the object. The
8706 previous predicate was too restrictive, and did not allow public
8707 protected operations, only task entries.
8709 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8711 * sem_ch5.adb, fname.adb: Minor reformatting.
8713 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8715 * einfo.adb (Is_Anonymous_Access_Type): New routine.
8716 * einfo.ads Update the placement of
8717 E_Anonymous_Access_Subprogram_Type along with all subtypes that
8719 (Is_Anonymous_Access_Type): New routine.
8720 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
8721 master for an access type subject to pragma No_Heap_Finalization.
8722 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
8723 allocated or deallocated does not finalization actions if the
8724 associated access type is subject to pragma No_Heap_Finalization.
8725 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
8726 * par-prag.adb Pragma No_Heap_Finalization does not need special
8727 processing from the parser.
8728 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
8729 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
8730 * sem_prag.adb Add an entry in table Sig_Flags for pragma
8731 No_Heap_Finalization.
8732 (Analyze_Pragma): Add processing for
8733 pragma No_Heap_Finalization. Update various error messages to
8734 use Duplication_Error.
8735 * sem_util.ads, sem_util.adb (No_Heap_Finalization): New routine.
8736 * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
8737 and corresponding pragma id.
8739 2017-04-25 Bob Duff <duff@adacore.com>
8741 * freeze.adb (Freeze_Record_Type): Use the
8742 underlying type of the component type to determine whether it's
8743 elementary. For representation clause purposes, a private type
8744 should behave the same as its full type.
8745 * fname.ads, fname.adb (Is_Predefined_File_Name):
8746 Make sure things like "system.ali" are recognized as predefined.
8748 2017-04-25 Javier Miranda <miranda@adacore.com>
8750 * debug.adb: Update documentation of -gnatd.6.

8754 * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
8755 element iterator when the name is an overloaded function call,
8756 one of whose interpretations yields an array.
8758 2017-04-25 Bob Duff <duff@adacore.com>
8760 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
8761 Is_Internal_Unit_Name): New functions for operating on unit
8762 names, as opposed to file names. There's some duplicated code
8763 with fname.adb, which is unfortunate, but it seems like we don't
8764 want to add dependencies here.
8765 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
8766 to Is_Predefined_Unit_Name; the former was wrong, because Uname
8767 is not a file name at all.
8768 * fname.ads, fname.adb: Document the fact that
8769 Is_Predefined_File_Name and Is_Internal_File_Name can be called
8770 for ALI files, and fix the code so it works properly for ALI
8771 files. E.g. these should return True for "system.ali".
8773 2017-04-25 Justin Squirek <squirek@adacore.com>
8775 * exp_util.adb (Add_Invariant): Removed,
8776 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
8777 and Add_Own_Invariant. (Add_Invariant_Check): Used
8778 for adding runtime checks from any kind of invariant.
8779 (Add_Inherited_Invariant): Generates invariant checks for
8780 class-wide invariants (Add_Interface_Invariants): Removed, code
8781 moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):
8782 Create a types own invariant procedure (Add_Parent_Invariants):
8783 Removed, code moved to Build_Invariant_Procedure_Body
8784 (Build_Invariant_Procedure_Body): Add refactored calls
8785 and integrated code from Add_Parent_Invariants and
8786 Add_Interface_Invariants.
8787 (Process_Type): Removed, the
8788 relavant code was inlined into both Add_Own_Invariant and
8789 Add_Inherited_Invariant.
8791 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8793 * make.adb, par-ch2.adb, sem_util.adb, scans.ads, sem_ch8.adb,

8810 and Build_Invariant_Procedure_Declaration.
8811 * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
8812 and Build_Invariant_Procedure_Declaration from exp_ch7
8813 and break-out Is_Untagged_Private_Derivation from
8814 Build_Invariant_Procedure_Body.
8815 (Replace_Type_References):
8816 Append an extra parameter to allow for dispatching replacements
8817 and add the corrasponding logic.
8818 (Type_Invariant): Remove
8819 Replace_Typ_Refs and replace its references with calls to
8820 Replace_Type_References.
8821 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
8823 2017-04-25 Bob Duff <duff@adacore.com>
8825 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): New function
8826 that returns True when appropriate.
8827 * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
8828 when compiling predefined files.
8829 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
8830 "gnat.adc" should not be considered a predefined file name.
8831 That required (or at least encouraged) a lot of cleanup of global
8832 variable usage. We shouldn't be communicating information via
8833 the global name buffer.
8834 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
8835 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

8841 configuration file whose name is a directory.

8855 * stringt.ads, stringt.adb, exp_dbug.adb, sem_dim.adb: Remove
8856 Add_String_To_Name_Buffer, to avoid using the global Name_Buf.
8857 Add String_To_Name with no side effects.
8859 2017-04-25 Justin Squirek <squirek@adacore.com>
8861 * sem_ch3.adb (Analyze_Declarations): Add
8862 additional condition for edge case.
8864 2017-04-25 Bob Duff <duff@adacore.com>
8866 * par-ch2.adb, scans.ads, scn.adb: Do not give an error for
8867 reserved words inside pragmas. This is necessary to allow the
8868 pragma name Interface to be used in pragma Ignore_Pragma.
8869 * par.adb: Minor comment fix.
8871 2017-04-25 Javier Miranda <miranda@adacore.com>
8873 * a-tags.ads, a-tags.adb (Type_Is_Abstract): Renamed as Is_Abstract.

8894 * sem_ch5.adb (Analyze_Assignment): Reset Full_Analysis flag on
8895 the first pass over an assignment statement with target names,
8896 to prevent the generation of subtypes (such as discriminated
8897 record components)that may carry the target name outside of the
8898 tree for the assignment. The subtypes will be generated when
8899 the assignment is reanalyzed in full.
8900 (Analyze_Target_Name): Handle properly class-wide types.
8902 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

8910 and resolve the triaged expression because all substitutions
8911 refer to the proper entities. Update the replacement of

8914 For_Freeze. Add local variable Build_Body. Inherited DIC pragmas
8915 are now only processed when freezing occurs. Build a body only

9659 (Check_Dependency_Clause): Properly detect a match between two
9660 'Result attributes. Update the various post-match cases to use
9661 Is_Already_Matched as this routine now automatically recognizes

9663 (Is_Already_Matched): New routine.
9664 (Remove_Extra_Clauses): New routine.
9665 (Report_Extra_Clauses): Remove the detection of ... => null

9724 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
9725 an object declaration for an array type with a modular index type
9726 with the size of Long_Long_Integer. Special processing is needed
9727 in this case to compute reliably the size of the object, and
9728 eventually to raise Storage_Error, when wrap-around arithmetic
9729 might compute a meangingless size for the object.
9731 2017-01-23 Justin Squirek <squirek@adacore.com>

9738 * sem_res.adb (Resolve_Call): In the part of the code where
9739 it is deciding whether to turn the call into an indexed
9740 component, avoid doing so if the call is to an instance of
9741 Unchecked_Conversion. Otherwise, the compiler turns it into an
9742 indexed component, and resolution of that turns it back into a
9743 function call, and so on, resulting in infinite recursion.
9744 * sem_util.adb (Needs_One_Actual): If the first formal has a
9745 default, then return False.

9790 2017-01-20 Ed Schonberg <schonberg@adacore.com>
9792 * sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
9793 must be treated as delayed aspect even if the expression is

9816 the prefix is not null) when the prefix denotes an object of an
9817 access type; that is, when there is an implicit dereference.

9847 returns a limited view of a type and at the point of the call the
9848 function is not declared in the extended main unit then replace
9849 it with the non-limited view, which must be available. If the
9850 called function is in the extended main unit then no action is
9851 needed since the back-end handles this case.

9865 * sem_ch3.adb (Complete_Private_Subtype): If the scope of the
9866 base type differs from that of the completion and the private
9867 subtype is an itype (created for a constraint on an access
9868 type e.g.), set Delayed_Freeze on both to prevent out-of-scope
9871 2017-01-20 Hristian Kirtchev <kirtchev@adacore.com>
9873 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
9874 When inheriting the SPARK_Mode of a prior expression function,

10416 * ali.ads, ali.adb (Static_Elaboration_Model_Used): Remove unused flag.
10417 * g-locfil.ads: Minor comment fix.
10419 2017-01-13 Bob Duff <duff@adacore.com>
10421 * binde.adb (Elab_New): New elaboration order algorithm
10422 that is expected to cause fewer ABE issues. This is a work in
10423 progress. The new algorithm is currently disabled, and can be
10424 enable by the -dp switch, or by modifying the Do_Old and Do_New
10425 etc. flags and rebuilding. Experimental code is included to
10426 compare the results of the old and new algorithms.
10427 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
10428 can have multiple of these tables, so the old and new algorithms
10430 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
10431 parameter of type array. This avoids the global variable, and
10432 allows bounds checking (which is normally defeated by the tables
10433 packages). It also ensures that the Elab_Order is read-only
10435 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
10436 subprograms that need it, as above.
10437 * debug.adb: Document new -dp switch. Modify doc of old -do
10439 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
10440 and Bindgen. Move writing of closure (-R and -Ra switches)
10441 to Binde; that's more convenient.
10443 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10445 * sem_ch6.adb (Analyze_Expression_Function): If the expression
10446 function is a completion, all entities referenced in the
10447 expression are frozen. As a consequence, a reference to an
10448 uncompleted private type from an enclosing scope is illegal.
10450 2017-01-13 Javier Miranda <miranda@adacore.com>
10452 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
10453 (Analyze_Subprogram_Body_Helper): At the occurrence of an
10454 expression function declaration that is a completion, its
10455 expression causes freezing (AI12-0103).
10457 2017-01-13 Vadim Godunko <godunko@adacore.com>
10459 * a-coinho-shared.adb: Fix memory leaks in Constant_Reference and

10468 * exp_ch3.adb (Default_Initialize_Object): Do not default
10469 initialize an object when it is of a task type and restriction
10470 No_Tasking is in effect because the initialization is obsolete.
10471 * exp_ch9.adb (Build_Master_Entity): Do not generate a master when
10472 restriction No_Tasking is in effect.
10473 (Build_Master_Renaming): Do not rename a master when restriction
10474 No_Tasking is in effect.
10476 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10478 * sem_aggr.adb (Resolve_Array_Aggregate): The code that verifies
10479 the legality of An others clause applies as well to a choice in
10480 an Iterated_component_ association.
10481 (Resolve_Iterated_Component_Association): An others choice
10483 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An
10484 Iterated_Component_Association is not static.
10486 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
10488 * exp_ch3.adb (Freeze_Type): Mark the Ghost mode as set in case
10489 control is passed to the expresion handler before the new mode
10491 * sem_ch12.adb (Analyze_Package_Instantiation,
10492 Analyze_Subprogram_Instantiation): Mark the Ghost mode as set
10493 in case control is passed to the expresion handler before the
10496 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
10498 * sem_aggr.adb, sem_ch3.adb, inline.adb, sem_util.adb, exp_ch4.adb,
10499 exp_aggr.adb: Minor reformatting.
10501 2017-01-13 Gary Dismukes <dismukes@adacore.com>
10503 * inline.adb: Minor reformatting and typo fix.
10505 2017-01-13 Ed Schonberg <schonberg@adacore.com>

10508 from sem_aggr.adb, for use elsewhere.
10509 * sem_ch3.adb (Analyze_Object_Declaration): Use Choice_List.
10510 * sem_aggr.adb (Resolve_Array_Aggregate): Remove
10511 Iterated_Component_Present.
10512 * exp_aggr.adb: Use Choice_List throughout, to handle
10513 Iterated_Component_Associations.
10514 (Gen_Loop): Generate proper loop for an
10515 Iterated_Component_Association: loop variable has the identifier
10516 of the original association. Generate a loop even for a single
10517 component choice, in order to make loop parameter visible in
10519 (Flatten): An Iterated_Component_Association is not static.
10521 2017-01-13 Yannick Moy <moy@adacore.com>
10523 * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
10524 float exponentiation for statically known small negative values
10525 is the reciprocal of the exponentiation for the opposite value
10527 * s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):
10528 Ensure that the value of float exponentiation for negative values
10529 is the reciprocal of the exponentiation for the opposite value

10538 expression in delay statement as OK for volatile context.
10540 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10542 * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
10543 mode a choice that is a subtype with a static predicate is
10544 replaced by the values it covers. This transformation must not
10545 be performed in ASIS mode, to preserve the source for analysis.
10547 2017-01-13 Justin Squirek <squirek@adacore.com>
10549 * nlists.ads: Correct minor typo.
10551 2017-01-13 Gary Dismukes <dismukes@adacore.com>
10553 * sem_ch13.adb: Minor reformatting and typo fix.
10555 2017-01-13 Ed Schonberg <schonberg@adacore.com>

10558 Iterated_Component_Association is a named association in an
10560 * sem_aggr.adb (Resolve_Iterated_Component_Association): New
10561 procedure, subsidiary of Resolve_Array_Aggregate, to analyze
10562 and resolve the discrete choices and the expression of the
10564 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
10565 Loop_Actions and Box_Present are attributes of
10566 N_Iterated_Component_Association nodes. Box_Present is always
10567 False in this case.
10568 * sprint.adb (Sprint_Node): An Iterated_Component_Association
10569 has a Discrete_Choices list, as specified in the RM. A
10570 Component_Association for aggregate uses instead a Choices list.
10571 We have to live with this small inconsistency because the new
10572 construct also has a defining identifier, and there is no way
10573 to merge the two node structures.
10575 2017-01-13 Yannick Moy <moy@adacore.com>
10577 * inline.adb (Remove_Aspects_And_Pragmas): Add Unused to the

10584 * sem_ch3.adb (Resolve_Aspects): New procedure, subsidiary of
10585 Analyze_Declarations, to analyze and resolve the expressions of
10586 aspect specifications in the current declarative list, so that
10587 the expressions have proper entity and type info. This is needed
10588 for ASIS when there is no subsequent expansion to generate this
10589 semantic information.
10590 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
10591 original expression, to suppress cascaded errors when expression
10592 has been constant-folded.
10593 (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
10594 ASIS mode, because there is no subsequent expansion to decorate
10597 2017-01-13 Yannick Moy <moy@adacore.com>
10599 * inline.adb, inline.ads (Call_Can_Be_Inlined_In_GNATprove_Mode):
10600 New function to detect when a call may be inlined or not in
10602 (Expand_Inlined_Call): Ensure that a temporary
10603 is always created in the cases where a type conversion may be
10604 needed on an input parameter in GNATprove mode, so that GNATprove
10605 sees the check to perform.
10606 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
10607 when not applicable due to actual requiring type conversion
10608 with possible check but no temporary value can be copied for
10609 GNATprove to see the check.

10788 * frontend.adb (Frontend): Move the implicit with for System
10789 in GNATprove_Mode here as it ismore correct this way; the old
10790 place only worked by chance, since there were no overloaded names.
