434 * gnatbind.adb (Scan_Bind_Arg): Simplify test to remove always true
435 condition.
436 * namet.adb (Copy_One_Character): Add assumption for static analysis,
437 as knowledge that Hex(2) is in the range 0..255 is too complex for
438 CodePeer.
439 (Finalize): Add assumption for static analysis, as the fact that there
440 are symbols in the table depends on a global invariant at this point in
441 the program.
442 * set_targ.adb (Check_Spaces): Justify CodePeer false positive message.
443 * stylesw.adb (Save_Style_Check_Options): Rewrite to avoid test always

486 * exp_util.adb (Find_Interface_Tag): Default initialize AI_Tag.
487 * freeze.adb (Check_Component_Storage_Order): Default initialize
488 Comp_Byte_Aligned rather than silencing messages with pragma
489 Warnings(Off), which does not work for CodePeer initialization
490 messages, and given that here the possible read of an unitialized value
491 depends on a proper use of parameters by the caller.
492 * inline.adb (Expand_Inlined_Call): Default initialize Lab_Decl, Targ.
493 * sem_ch12.adb (Build_Operator_Wrapper): Default initialize Expr.

501 Save_Full_Analysis.
502 * sem_ch6.adb (Analyze_Function_Return): Default initialize Obj_Decl,
503 and restructure code to defend against previous errors, so that, in
504 that case, control does not flow to the elsif condition which read an
505 uninitialized Obj_Decl.
506 * sem_ch9.adb (Analyze_Requeue): Default initialize Synch_Type.
507 (Check_Interfaces): Default initialize Full_T_Ifaces and Priv_T_Ifaces,
508 which seem to be left uninitialized and possibly read in some cases.
509 * sem_dim.adb (Analyze_Aspect_Dimension_System): Retype Position more
510 precisely. This requires to exchange the test for exiting in case of
511 too many positions and the increment to Position, inside the loop.
512 * sem_eval.adb (Eval_Concatenation): Default initialize Folded_Val,
513 which cannot be read uninitialized, but the reasons for that are quite
514 subtle.
515 * sem_intr.adb (Check_Intrinsic_Call): Default initialize Rtyp.
516 * sem_prag.adb (Collect_Subprogram_Inputs_Outputs): Default initialize
517 Spec_Id.
518 * sem_res.adb (Make_Call_Into_Operator): Default initialize Opnd_Type,
519 and test for presence of non-null Opnd_Type before testing its scope,
520 in a test which would read its value uninitialized, and is very rarely
521 exercized (it depends on the presence of an extension of System).
522 * sem_spark.ads: Update comment to fix name of main analysis procedure.
523 * sem_warn.adb (Warn_On_Known_Condition): Default initialize
524 Test_Result.
525 * set_targ.adb (FailN): Mark procedure with No_Return.
526 * stylesw.adb (Save_Style_Check_Options): Delete useless code to
527 initialize all array Options to white space, as there is already code

529 procedure.
531 2017-11-09 Eric Botcazou <ebotcazou@adacore.com>
533 * exp_ch11.adb (Possible_Local_Raise): Do not issue the warning for

557 * namet.ads, namet.adb (Valid_Name_Id): New subtype that excludes
558 Error_Name and No_Name. Use this (versus Name_Id) to indicate which
559 objects can have those special values. Valid_Name_Id could usefully be
560 used all over the compiler front end, but that's too much trouble for
561 now. If we did that, we might want to rename:
562 Name_Id --> Optional_Name_Id, Valid_Name_Id --> Name_Id.
563 For parameters of type Valid_Name_Id, remove some redundant tests,
564 including the ones found by CodePeer. Use Is_Valid_Name instead of
565 membership test when appropriate.
566 (Error_Name_Or_No_Name): Delete this; it's no longer needed.
567 * sem_ch2.adb (Analyze_Identifier): Use "not Is_Valid_Name" instead of
568 "in Error_Name_Or_No_Name".

1968 forces the analysis of the expression before rewriting it as a body, so
1969 that freeze nodes can appear in the proper scope.

2318 the expression to be used in the generated attribute specification
2319 (rather than relocating it) to avoid resolving a potentially malformed
2320 tree when the expression is resolved through an ASIS-specific call to
2321 Resolve_Aspect_Expressions. This manifests itself as a crash on a
2322 function with parameter associations.
2324 2017-09-25 Yannick Moy <moy@adacore.com>

2358 call that appears in a classwide precondition and that mentions an
2359 access formal of the subprogram, must use the accessibility level of

2377 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression for aspect

2445 routine is already provided by Einfo.
2446 * einfo.adb (Has_Null_Abstract_State): Replace with the body from

3160 to libgnat subdirectory.
3162 2017-09-08 Yannick Moy <moy@adacore.com>
3164 * sem_aux.adb, sem_aux.ads (Get_Called_Entity): New function to
3165 return the entity associated with the call.
3166 * sem_util.adb, sem_util.ads (Check_Function_Writable_Actuals):
3167 Replace the internal Get_Function_Id with the new
3168 Sem_Aux.Get_Called_Entity.
3169 (Iterate_Call_Parameters): New
3170 procedure to iterate on formals and actuals at the same time.
3171 * sem_ch12.adb (Analyze_Subprogram_Instantiation):
3172 Set SPARK_Mode from spec when set, for analysis
3173 of instance. Restore after analysis of instance.
3174 (Instantiate_Subprogram_Body): Set SPARK_Mode from body when
3175 set, for analysis of body instance. Restored automatically at
3176 the end of the subprogram.
3177 * gnat1drv.adb (Adjust_Global_Switches): Set
3178 Check_Validity_Of_Parameters to False in GNATprove mode.
3179 * opt.ads (Check_Validity_Of_Parameters): Document switch to
3180 set option.
3182 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3184 * sem_util.adb (NCT_Tables_In_Use): Move to library level from...
3185 (New_Copy_Tree): ...there. Reset the hash tables only if they
3186 were used in the previous invocation.
3187 * s-htable.adb: Fix typo.
3189 2017-09-08 Bob Duff <duff@adacore.com>
3191 * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
3193 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3195 * sem_aggr.adb: minor style fix.
3197 2017-09-08 Bob Duff <duff@adacore.com>
3199 * sprint.adb (Write_Corresponding_Source): Ignore if there is
3200 no current source file.
3201 (Write_Name_With_Col_Check, Write_Name_With_Col_Check_Sloc):
3202 Print something helpful in case N is invalid.
3203 * sprint.ads: Minor comment fix.
3205 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3207 * exp_aggr.adb: (Aggr_Assignment_OK_For_Backend): Add early return for
3208 access types.
3210 2017-09-08 Bob Duff <duff@adacore.com>
3212 * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
3213 Ada_2020, along the same lines as the other Ada version pragmas.
3215 2017-09-08 Gary Dismukes <dismukes@adacore.com>
3217 * sem_ch12.adb: Minor typo fixes and reformatting.
3219 2017-09-08 Yannick Moy <moy@adacore.com>
3221 * sem_aggr.adb (Resolve_Record_Aggregate):
3222 Rewrite bounds of aggregate subexpressions which may depend on
3223 discriminants of the enclosing aggregate.
3225 2017-09-08 Yannick Moy <moy@adacore.com>
3227 * sem_ch5.adb: Prevent assertion failure on illegal code.
3229 2017-09-08 Yannick Moy <moy@adacore.com>
3231 * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
3232 calling Renamed_Entity on an entity which cannot be a renaming.
3234 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3236 * exp_aggr.adb: Add with & use clause for Urealp.
3237 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
3238 elementary types instead of just discrete types.
3239 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
3240 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
3241 Be prepared for the FP zero value in the memset case. Add small
3242 guard.
3244 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3246 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
3247 of loop.
3249 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
3251 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
3252 of New_Copy because the latter leaves the syntactic structure of
3253 the tree inconsistent (a child is accessible through two parents)
3254 and prevents proper replication of itypes by subsequent calls
3255 to New_Copy_Tree.
3256 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
3257 New_Copy because the latter leaves the syntactic structure of the
3258 tree inconsistent (a child is accessible through two parents)
3259 and prevents proper replication of itypes by subsequent calls
3260 to New_Copy_Tree.
3261 * sem_util.adb (In_Subtree): New routine.
3262 (New_Copy_Tree): Reimplemented.
3263 * sem_util.ads (In_Subtree): New routine.
3264 (New_Copy_Tree): Reimplemented.
3266 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3268 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
3269 for aspect Default_Value is a static scalar value, but it does
3270 not freeze the type. Yhis allows for subsequent representation
3271 clauses for the type.
3273 2017-09-08 Javier Miranda <miranda@adacore.com>
3275 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
3276 not add entries into the undefined reference table when we are
3277 compiling with errors ignored.
3279 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3281 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
3282 check if the instance is within an enclosing instance body. The
3283 formal package was legal in the enclosing generic, and is
3284 legal in the enclosing instantiation. This optimisation may be
3285 applicable elsewhere, and it also removes spurious errors that
3286 may arise with on-the-fly processing of instantiations that
3287 contain Inline_Always subprograms.
3289 2017-09-08 Vincent Celier <celier@adacore.com>
3291 * gnatcmd.adb: Disregard empty argument of GNAT driver.
3293 2017-09-08 Justin Squirek <squirek@adacore.com>
3295 * checks.adb (Insert_Valid_Check): Manually decorate
3296 the generated temporary for range valdity checks.
3298 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3300 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
3302 2017-09-08 Justin Squirek <squirek@adacore.com>
3304 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
3305 case to handle underscore flags.
3306 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
3307 new procedure to handle underscores.
3309 2017-09-08 Javier Miranda <miranda@adacore.com>
3311 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
3312 divisions with fixed point results to avoid generating twice
3313 the runtime check on divide by zero.
3314 * checks.adb (Apply_Divide_Checks): Ensure that operands are
3315 not evaluated twice (once for their runtime checks and once for
3316 their regular computation).
3318 2017-09-08 Yannick Moy <moy@adacore.com>
3320 * sem_prag.adb (Analyze_Part_Of): Add missing
3321 return statements after issuing errors. Add detection of
3322 out-of-order item and single concurrent type.

3779 2017-09-08 Nicolas Roche <roche@adacore.com>
3781 * s-hibaen.ads: Remove obsolete file.
3783 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3785 * a-locale.ads: Add comment explaining the state of this package.
3787 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3789 * sem_util.adb (Is_CCT_Instance): Allow calls in the context
3790 of packages.
3791 * sem_prag.ads, sem_prag.adb (Find_Related_Declaration_Or_Body):
3792 allow calls in the context of package spec (for pragma
3793 Initializes) and bodies (for pragma Refined_State).
3795 2017-09-08 Bob Duff <duff@adacore.com>
3797 * checks.adb (Insert_Valid_Check): Copy the Do_Range_Check flag to the
3798 new Exp.
3800 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3802 * debug.adb (dA): Adjust comment.
3803 * gnat1drv.adb (Gnat1drv): Likewise.
3804 * opt.ads (List_Representation_Info_Extended): New variable.
3805 * repinfo.adb (List_Record_Info): Split implementation into...
3806 (Compute_Max_Length): ...this. Recurse on records if requested.
3807 (List_Record_Layout): Likewise.
3808 * switch-c.adb (Scan_Front_End_Switches) <'R'>: Use case
3809 statement, accept '0' and set List_Representation_Info_Extended
3810 on 'e'.
3811 * usage.adb (Usage): Document new -gnatRe variant.
3813 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3815 * sem_prag.adb (Analyze_Pragma, case Default_Storage_Pool):
3816 Do not save the given entity in the global variable Default_Pool
3817 if the pragma appears within a generic unit.
3819 2017-09-08 Bob Duff <duff@adacore.com>
3821 * errout.adb (Delete_Warning): Do not
3822 decrement Warnings_Treated_As_Errors. This is called before
3823 Warnings_Treated_As_Errors has been incremented to account for
3824 this warning. Decrementing it here can lead to negative values
3825 of Warnings_Treated_As_Errors, raising Constraint_Error in
3826 checks-on builds, and causing the compiler to return an error
3827 code in checks-off builds.
3829 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3831 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
3832 entities of named concurrent types as Ref_Id and not of anonymous
3833 concurrent objects (because callers already know when a conversion
3834 is necessary and can easily do it); also, do not expect protected
3835 types or protected objects as Context_Id (because no flow-related
3836 SPARK pragmas are attached there); reflect these changes in a
3837 more precise comment.
3839 2017-09-08 Olivier Hainque <hainque@adacore.com>
3841 * g-altive.ads: Add documentation.
3843 2017-09-08 Bob Duff <duff@adacore.com>
3845 * sem_util.ads, debug.adb: Minor comment fix.
3846 * erroutc.ads: Comment fix.
3848 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3850 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
3851 for compatibility of component types of formal and actual in an
3852 instantiation of a child unit, when the component type of the
3853 formal is itself a formal of an enclosing generic.
3855 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3857 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
3858 sem_prag.adb to make it available for GNATprove; for concurrent
3859 types replace custom scope climbing with Scope_Same_Or_Within; for
3860 single concurrent objects add scope climbing (with Scope_Within),
3861 which was not there (that's the primary semantic change of this
3862 commit); also, when comparing a single concurrent object with
3863 its corresponding concurrent type rely on equality of types,
3864 not of objects (because that's simpler to code).
3865 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
3866 (Analyze_Global_Item): adjust special-casing of references to the
3867 current instance of a concurrent unit in the Global contracts
3868 of task types and single tasks objects; similar for references
3869 in the protected operations and entries of protected types and
3870 single protected objects (in all these cases the current instance
3871 behaves as an implicit parameter and must not be mentioned in
3872 the Global contract).
3874 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3876 * exp_ch6.adb (Expand_Call_Helper): Introduce temporary for
3877 function calls returning a record within a subprogram call,
3878 for C generation.
3880 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3882 * sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded
3883 name that designates the current instance of a child unit in its
3884 own body and appears as the prefix of a reference to an entity
3885 local to the child unit.
3886 * exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
3887 Minor reformatting.
3889 2017-09-08 Yannick Moy <moy@adacore.com>
3891 * sem_res.adb (Resolve_Equality_Op): Do not warn on comparisons that
3892 may be intentional.
3894 2017-09-08 Tristan Gingold <gingold@adacore.com>
3896 * sem_warn.adb (Check_Unused_Withs): Remove test that disabled
3897 warnings on internal units in configurable run time mode.
3899 2017-09-08 Bob Duff <duff@adacore.com>
3901 * sem_ch3.adb (Build_Derived_Private_Type): Inherit
3902 representation items from interfaces that the derived type
3903 implements, not just from the parent type.
3904 * sem_util.ads, sem_util.adb (Abstract_Interface_List): Change
3905 this to return an empty list when there are no interfaces.
3906 * einfo.ads, sem_ch13.adb: Minor comment fixes.
3907 * sem_attr.adb: Minor comment fix.
3909 2017-09-08 Doug Rupp <rupp@adacore.com>
3911 * sigtramp-vxworks.c [i386]: Adjust the kernel context for
3912 x86-vx7.
3914 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
3916 * exp_ch4.adb (Expand_N_Allocator): Generate a
3917 call to Allocate_Any_Controlled when the allocation does not
3918 require any initialization.
3920 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
3922 * sem_util.adb (Copy_Node_With_Replacement):
3923 Update the Renamed_Object field of a replicated object renaming
3924 declaration.
3926 2017-09-08 Patrick Bernardi <bernardi@adacore.com>
3928 * exp_ch9.adb (Is_Pure_Barrier): Allow type
3929 conversions and components of objects. Simplified the detection
3930 of the Count attribute by identifying the corresponding run-time
3931 calls.
3933 2017-09-08 Yannick Moy <moy@adacore.com>
3935 * exp_ch9.adb, exp_disp.adb, repinfo.adb, sem_ch12.adb, sem_dim.adb,
3936 sem_type.adb, sinfo.ads: Minor reformatting.
3938 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3940 * freeze.adb (Has_Incomplete_Compoent): New predicate, subsidiary
3941 of Freeze_Profile, used to inhibit the freezing of the profile
3942 of an expression function declared within a nested package, when
3943 some type in the profile depends on a private type declared in
3944 an enclosing package.
3946 2017-09-08 Bob Duff <duff@adacore.com>
3948 * gnat1drv.adb (Gnat1drv): Do not set the Force_ALI_Tree_File flag in
3949 the subunit case. It's still OK to set it in the "missing subunits"
3950 case, because that won't cause the obsolete .ali files that cause
3951 confusion.
3953 2017-09-08 Bob Duff <duff@adacore.com>
3955 * sinput-l.adb: Remove unused "with Unchecked_Conversion;". It's
3956 unclear why this didn't cause a warning.
3957 * a-uncdea.ads, a-unccon.ads: Add "Ada." to names in the
3958 pragmas. It's unclear why this didn't cause an error.
3960 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
3962 * exp_spark.adb (Expand_SPARK_N_Object_Renaming_Declaration):
3963 Reimplemented.
3964 (Expand_SPARK_Potential_Renaming): Code clean up.
3965 * sem_prag.adb (Analyze_Initialization_Item): Add a guard in case
3966 the item does not have a proper entity.
3967 (Analyze_Input_Item): Add a guard in case the item does not have a
3968 proper entity.
3969 (Collect_States_And_Objects): Include object renamings in the
3970 items being collected.
3971 (Resolve_State): Update the documentation of this routine.
3972 * sem_util.adb (Entity_Of): Add circuitry to handle
3973 renamings of function results.
3974 (Remove_Entity): New routine.
3975 (Remove_Overloaded_Entity): Take advantage of factorization.
3976 * sem_util.ads (Entity_Of): Update the documentation
3977 of this routine.
3978 (Remove_Entity): New routine.
3979 (Remove_Overloaded_Entity): Update the documentation of this
3980 routine.
3982 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3984 * repinfo.adb (List_Record_Info): During first loop,
3985 do not override the normalized position and first bit
3986 if they have already been set. Move fallback code
3987 for the packed case to the case where it belongs.
3988 * sem_ch13.adb (Adjust_Record_For_Reverse_Bit_Order):
3989 Also adjust the normalized position of components.
3990 (Adjust_Record_For_Reverse_Bit_Order_Ada_95): Likewise.
3992 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3994 * exp_disp.adb (Make_DT, Set_All_DT_Position): Handle properly
3995 the placement of a primitive operation O that renames an operation
3996 R declared in an inner package, and which is thus not a primitive
3997 of the dispatching type of O. In this case O is a new primitive
3998 and does not inherit its dispatch table position from R (which
3999 has none).
4001 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4003 * sem_dim.adb (Analyze_Dimension_If_Expression,
4004 Analyze_Dimension_Case_Expression): new subprograms to verify
4005 the dimensional correctness of Ada2012 conditional expressions,
4006 and set properly the dimensions of the construct.
4007 * sem_res.adb (Resolve_If_Expression, Resolve_Case_Expression)):
4008 call Analyze_Dimension.
4010 2017-09-08 Ed Schonberg <schonberg@adacore.com>

4013 loop on an interface declared as a private extension of another
4014 synchronized interface.
4016 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4018 * sem_ch12.adb (Check_Generic_Parent): New procedure within
4019 Analyze_Associations, to handle actual packages that depend on
4020 previous instances. If a package IAP that is an instantiation is
4021 used as an actual in a subsequent instantiation SI in the same
4022 scope, and IAP has a body, IAP must be frozen before SI. If
4023 the generic parent of IAP is itself declared in a previous
4024 instantiation in the same scope, that instantiation must also
4025 be frozen before SI.
4026 (Install_Body): Prevent double insertion of freeze node for
4027 instance.
4029 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4031 * sem_prag.adb (Resolve_State): Update the
4032 comment on documentation. Generate a reference to the state once
4033 resolution takes place.
4035 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4037 * sem_ch13.adb (Analyze_Aspect_Specifications, case
4038 Linker_Section): If the aspect applies to an object declaration
4039 with explicit initialization, do not delay the freezing of the
4040 object, to prevent access-before-elaboration in the generated
4041 initialization code.
4043 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4045 * a-wtdeio.adb (Put, all versions): Use Long_Long_Integer
4046 (Integer_Value (Item)) when the size of the fixed decimal type
4047 is larger than Integer.

4053 in order of increasing position in more cases.
4055 2017-09-07 Yannick Moy <moy@adacore.com>
4057 * a-exetim-mingw.ads: Add contract Global=>null
4058 on all operations that are modeled as having no read or write
4059 of global variables in SPARK.

4075 allow disabling the generation of implicit pragma Elaborate_All
4076 on task bodies.
4078 2017-09-07 Javier Miranda <miranda@adacore.com>
4080 * exp_disp.adb (Make_Tags): Avoid suffix counter
4081 in the external name of the elaboration flag. Required to fix
4082 the regressions introduced by the initial version of this patch.
4084 2017-09-07 Bob Duff <duff@adacore.com>
4086 * sem_ch6.adb (Analyze_Function_Return): Do not
4087 insert an explicit conversion to force the displacement of the
4088 "this" pointer to reference the secondary dispatch table in the
4089 case where the return statement is returning a raise expression,
4090 as in "return raise ...".
4092 2017-09-07 Arnaud Charlet <charlet@adacore.com>
4094 * sem_disp.adb (Is_User_Defined_Equality): Removed procedure.
4095 * sem_util.ads, sem_util.adb (Is_User_Defined_Equality): Copied

4109 definition.
4111 2017-09-07 Ed Schonberg <schonberg@adacore.com>
4113 * sem_dim.adb (Analyze_Dimension_Type_Conversion): New procedure
4114 to handle properly various cases of type conversions where the
4115 target type and/or the expression carry dimension information.
4116 (Dimension_System_Root); If a subtype carries dimension
4117 information, obtain the source parent type that carries the
4118 Dimension aspect.
4120 2017-09-07 Dmitriy Anisimkov <anisimko@adacore.com>
4122 * g-socket.adb, g-socket.ads (GNAT.Sockets.To_Ada): New routine.
4124 2017-09-07 Ed Schonberg <schonberg@adacore.com>
4126 * exp_attr.adb (Expand_N_Attribute_Reference, case 'Constrained):
4127 If the prefix is a reference to an object, rewrite it as an
4128 explicit dereference, as required by 3.7.2 (2) and as is done
4129 with most other attributes whose prefix is an access value.
4131 2017-09-07 Bob Duff <duff@adacore.com>
4133 * par-ch13.adb: Set the Inside_Depends flag if we are inside a
4134 Refined_Depends aspect.

4143 Account for the case where the are no lists to insert, but the
4144 secondary stack still requires management.

4176 in CodePeer mode, to support more legacy code automatically.
4178 2017-09-07 Ed Schonberg <schonberg@adacore.com>
4180 * exp_disp.adb (Replace_Formals): If thr formal is classwide,
4181 and thus not a controlling argument, preserve its type after
4182 rewriting because it may appear in an nested call with a classwide
4183 parameter.
4185 2017-09-07 Arnaud Charlet <charlet@adacore.com>
4187 * comperr.adb (Delete_SCIL_Files): Handle case of

4193 clause for a unit U appears in a context that includes a regular
4194 with_clause on U, rewrite the redundant private clause into a null
4195 statement, rather than removing it altogether from the context,
4196 so that ASIS tools can reconstruct the original source.
4198 2017-09-07 Ed Schonberg <schonberg@adacore.com>
4200 * sem_ch13.adb (Check_Aspect_At_Freeze_Point): The expression
4201 for aspect Small can be of any real type (not only a universal
4202 real literal) as long as it is a static constant.
4204 2017-09-07 Thomas Quinot <quinot@adacore.com>

4248 IP routine to initialize the object components and for completing
4249 the elaboration of dispatch tables.
4250 * exp_ch3.adb (Build_Init_Procedure): Improve the code
4251 generated in the IP routines by means of keeping separate
4252 the initialization of the object components from the
4253 initialization of its dispatch tables. (Init_Secondary_Tags):
4254 Adding new formal (Init_Tags_List) and adjusting calls to
4255 Ada.Tags.Set_Dynamic_Offset_To_Top since it has a new formal;
4256 adjusting also calls to Ada.Tags.Register_Interface_Offset
4257 because the type of one of its formals has been changed.
4258 * a-tags.ads, a-tags.adb (Register_Interface_Offset): Profile
4259 modified. Instead of receiving a pointer to an object this
4260 routine receives now a primary tag.
4261 (Set_Dyanic_Offset_To_Top): Profile modified. This routine receives an
4262 additional formal: the tag of the primary dispatch table.
4263 * exp_disp.ads (Elab_Flag_Needed): New subprogram.
4264 * exp_disp.adb (Elab_Flag_Needed): New subprogram.
4265 (Make_Tags): Adding the declaration of the elaboration flag (if needed).

4276 2017-09-07 Arnaud Charlet <charlet@adacore.com>
4278 * sem_util.adb (Check_Part_Of_Reference): rename Conc_Typ to Conc_Obj
4279 (because it refers to the anonymous concurrent object, not its type);
4280 fix condition for emitting error message about task/protected type,
4282 2017-09-07 Bob Duff <duff@adacore.com>
4284 * binde.adb (Debug_Flag_Old): If both -do and -dp
4285 are specified, behave as if just -do was specified, rather than
4286 using a mixture.
4288 2017-09-07 Nicolas Roche <roche@adacore.com>
4290 * system-vxworks-sparcv9.ads, s-vxwork-m68k.ads, s-vxwork-mips.ads,
4291 system-vxworks-m68k.ads, system-vxworks-mips.ads: Removed.
4293 2017-09-07 Arnaud Charlet <charlet@adacore.com>
4295 * sem_prag.adb (Find_Role): The Global_Seen flag
4296 is now consulted not only for abstract states and variables,
4297 but for all kinds of items.
4298 (Collect_Subprogram_Inputs_Outputs): Do not process formal
4299 generic parameters, because unlike ordinary formal parameters,
4300 generic formals only act as input/ outputs if they are explicitly
4301 mentioned in a Global contract.
4303 2017-09-07 Yannick Moy <moy@adacore.com>
4305 * ghost.adb (Check_Ghost_Context): Do not err on ghost code inside
4306 predicate procedure. Check predicate pragma/aspect with Ghost entity.
4307 * exp_ch6.adb, par-ch6.adb, sem_ch13.adb, sem_prag.adb; Minor
4308 reformatting.
4310 2017-09-07 Ed Schonberg <schonberg@adacore.com>
4312 * sem_aggr.adb: Move New_Copy_Tree_And_Dimensions to sem_dim
4313 (code cleanup);
4314 * sem_ch3.adb (Build_Derived_Record_Type):i Call
4315 Copy_Dimensions_Of_Components after creating the copy of the
4316 record declaration.
4317 * sem_dim.ads, sem_dim.adb (Copy_Dimensions_Of_Components): For a
4318 derived recor type, copy the dikensions if any of each component
4319 of the parent record to the corresponding component declarations
4320 of the derived record. These expressions are used among other
4321 things as default values in aggregates with box associations.
4322 * a-dirval-mingw.adb, g-cgi.adb, gnatcmd.adb, lib-xref.adb,
4323 repinfo.adb, sem_attr.adb, sem_ch10.adb, sem_ch6.adb, sem_prag.adb:
4324 Minor reformatting.
4326 2017-09-07 Arnaud Charlet <charlet@adacore.com>
4328 * sem_util.adb: Remove extra space after THEN.
4330 2017-09-07 Eric Botcazou <ebotcazou@adacore.com>
4332 * sem_ch7.adb (Has_Referencer): For a subprogram renaming,
4333 also mark the renamed subprogram as referenced.
4335 2017-09-07 Ed Schonberg <schonberg@adacore.com>
4337 * par-ch6.adb (P_Subprogram): Improve error message on null
4338 procedure with misplaced aspect specification, which the parser
4339 first attempts to interpret as a malformed expression function.
4341 2017-09-07 Gary Dismukes <dismukes@adacore.com>
4343 * sem_attr.adb (Analyze_Attribute_Old_Result):
4344 Allow attributes Result and Old in the case of an expression
4345 function.
4347 2017-09-07 Justin Squirek <squirek@adacore.com>
4349 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Propagate
4350 Volatile to subcomponents.
4352 2017-09-07 Bob Duff <duff@adacore.com>
4354 * exp_ch7.adb (Find_Last_Init): Check for the
4355 case where a build-in-place function call has been replaced by a
4356 'Reference attribute reference.
4358 2017-09-07 Eric Botcazou <ebotcazou@adacore.com>
4360 * sem_ch7.adb (Has_Referencer): Recurse on Actions of freeze
4361 nodes.
4363 2017-09-07 Bob Duff <duff@adacore.com>
4365 * exp_ch6.adb (Make_Build_In_Place_Call_In_Object_Declaration,
4366 Make_Build_In_Place_Call_In_Anonymous_Context): Do not use the
4367 secondary stack for all functions that return limited tagged
4368 types -- just do it for dispatching calls. Misc cleanup.
4369 * sem_util.ads, sem_util.adb (Unqual_Conv): New function to
4370 remove qualifications and type conversions. Fix various bugs
4371 where only a single level of qualification or conversion was
4372 removed, so e.g. "T1'(T2'(X))" would incorrectly return "T2'(X)"
4373 instead of "X".
4374 * checks.adb, exp_util.ads, exp_util.adb, sem_res.adb: Misc related
4375 cleanup.
4377 2017-09-07 Ed Schonberg <schonberg@adacore.com>
4379 * sem_ch6.adb (setr_Actual_Subtypes): Within a predicate function
4380 do not create actual subtypes that may generate further predicate
4381 functions.
4382 * sem_ch13.adb (Build_Predicate_Functions): Indicate that entity
4383 of body is a predicate function as well.
4384 (Resolve_Aspect_Expressions, Resolve_Name): For a component
4385 association, only the expression needs resolution, not the name.
4386 (Resolve_Aspect_Expressions, case Predicates): Construct and
4387 analyze the predicate function declaration in the scope of the
4388 type, before making the type and its discriminants visible.
4390 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
4392 * gcc-interface/decl.c (warn_on_field_placement): Issue the warning
4393 only if the record type itself comes from source.
4395 2017-09-06 Gary Dismukes <dismukes@adacore.com>
4397 * sem_ch5.adb: Minor reformatting and a typo fix
4399 2017-09-06 Arnaud Charlet <charlet@adacore.com>
4401 * sinput-l.ads: minor remove extra period at the end of comment
4403 2017-09-06 Arnaud Charlet <charlet@adacore.com>
4405 * sem_prag.adb (Add_Item_To_Name_Buffer): remove support for
4406 E_Discriminant.
4407 (Find_Role): remove support for E_Discriminant.
4409 2017-09-06 Javier Miranda <miranda@adacore.com>
4411 * exp_ch6.adb (Expand_Simple_Function_Return):
4412 Add missing implicit type conversion to force displacement of the
4413 "this" pointer.
4415 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>
4417 * sem_ch3.adb, sem_aux.adb, sem_res.adb: Minor reformatting.
4419 2017-09-06 Yannick Moy <moy@adacore.com>
4421 * sem_ch12.adb (Analyze_Instance_And_Renamings): Refactor to set
4422 global variable Ignore_SPARK_Mode_Pragmas_In_Instance only once.
4424 2017-09-06 Bob Duff <duff@adacore.com>
4426 * sem_ch8.adb: Change Assert to be consistent with
4427 other similar ones.
4429 2017-09-06 Bob Duff <duff@adacore.com>
4431 * binde.adb (Find_Elab_Order): Do not run Elab_Old unless
4432 requested. Previously, the -do switch meant "run Elab_New and
4433 Elab_Old and use the order chosen by Elab_Old, possibly with
4434 debugging printouts comparing the two orders." Now it means
4435 "do not run Elab_New." This is of use if there are bugs that
4436 cause Elab_New to crash.
4437 (Elab_Position, Num_Chosen): Change type to Nat, to avoid various
4438 type conversions.
4439 * ali.ads (Elab_Position): Change type to Nat, to avoid various
4440 type conversions.
4442 2017-09-06 Arnaud Charlet <charlet@adacore.com>
4444 * sem_prag.adb (Check_Mode_Restriction_In_Enclosing_Context): Fix
4445 reference to SPARK RM.
4447 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
4449 * layout.adb: Use SSU short hand consistently throughout the file.
4451 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
4453 * freeze.adb (Freeze_Record_Type)
4454 <Sized_Component_Total_Round_RM_Size>: New local variable to
4455 accumulate the rounded RM_Size of components. Update it for
4456 every component whose RM_Size is statically known. Add missing
4457 guard to check that bit packing is really required before issuing
4458 the error about packing. Swap condition for clarity's sake.
4459 * sem_prag.adb (Usage_Error): Fix reference to SPARK RM in comment.
4461 2017-09-06 Fedor Rybin <frybin@adacore.com>
4463 * makeutl.adb, makeutl.ads, mlib.adb, mlib.ads, mlib-fil.adb,

4477 prj-util.adb, prj-util.ads, sinput-p.adb, sinput-p.ads: Remove obsolete
4478 project manager sources.
4480 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4482 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
4483 entity of a mutable type and the right-hand side is a conditional
4484 expression, resolve the alternatives of the conditional using
4485 the base type of the target entity, because the alternatives
4486 may have distinct subtypes. This is particularly relevant if
4487 the alternatives are aggregates.
4489 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4491 * checks.adb (Apply_Predicate_Check): If the expression is an
4492 aggregate that is the RHS of an assignment, apply the check to
4493 the LHS after the assignment, rather than to the aggregate. This
4494 is more efficient than creating a temporary for the aggregate,
4495 and prevents back-end crashes when the aggregate includes a
4496 dynamic "others' association.
4498 2017-09-06 Yannick Moy <moy@adacore.com>
4500 * sem_ch12.adb (Analyze_Instance_And_Renamings):
4501 Set variable to ignore SPARK_Mode in instance before the analysis
4502 of the generated package declaration.
4504 2017-09-06 Yannick Moy <moy@adacore.com>
4506 * sem_res.adb (Resolve_Call): Do not issue a
4507 message for calls inside expression function, unless body was
4508 seen and is candidate for inlining.
4510 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4512 * sem_aux.adb (Is_Generic_Formal): Handle properly formal packages.
4513 * sem_ch3.adb (Analyze_Declarations): In a generic subprogram
4514 body. do not freeze the formals of the generic unit.
4516 2017-09-06 Gary Dismukes <dismukes@adacore.com>
4518 * errout.adb (Error_Msg): Separate the
4519 treatment for warning vs. style messages in inlinings and
4520 instantiations. Prevents blowups on calls to Warn_Insertion for
4521 style messages, which should not be called in that case because
4522 Warning_Msg_Char is not set.
4524 2017-09-06 Justin Squirek <squirek@adacore.com>
4526 * sem_prag.adb (Check_VFA_Conflicts): Created
4527 to group all Volatile_Full_Access checks relating to other
4528 representation pragmas (Mark_Component_Or_Object): Created
4529 to centeralize the flagging of attributes for the record type
4530 component case, a pragma applied individually to a component, and
4531 the object case.
4532 (Process_Atomic_Independent_Shared_Volatile):
4533 Add propagation of certain pragmas to record components and move
4534 evaluation of VFA checks
4536 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4538 * sem_prag.adb (Check_Postcondition_Use_In_Inlined_Subprogram):
4539 Do not warn on conditions that are not obeyed for Inline_Always
4540 subprograms, when assertions are not enabled.
4542 2017-09-06 Arnaud Charlet <charlet@adacore.com>
4544 * sem_util.adb (Unique_Entity): For abstract states return their
4545 non-limited view.
4547 2017-09-06 Bob Duff <duff@adacore.com>
4549 * sem_ch12.adb (Copy_Generic_Node): When we copy a node
4550 that is a proper body corresponding to a stub, we defer the
4551 adjustment of the sloc until after the correct adjustment has
4552 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
4553 the adjustment, because it will be outside the range in (the old,
4554 incorrect) S_Adjustment.
4555 * inline.adb: Use named notation for readability and uniformity.
4556 * sinput-l.adb: Minor improvements to debugging output printed
4557 for Debug_Flag_L.
4558 * sinput-l.ads (Create_Instantiation_Source): Minor comment
4559 correction.

4565 2017-09-06 Sylvain Dailler <dailler@adacore.com>
4567 * sem_eval.adb (Compile_Time_Known_Value_Or_Aggr): Adding a
4568 case when Op is of kind N_Qualified_Expression. In this case,
4569 the function is called recursively on the subexpression like in
4570 other cases.
4571 * make.adb: Minor reformatting
4573 2017-09-06 Justin Squirek <squirek@adacore.com>
4575 * einfo.adb (Set_Linker_Section_Pragma): Modify
4576 Set_Linker_Section_Pragma to be consistant with the "getter"
4577 Linker_Section_Pragma.
4578 * exp_ch5.adb (Expand_Formal_Container_Loop): Add proper error
4579 checking for container loops so that the index cursor is not
4580 directly changable by the user with the use of E_Loop_Parameter.
4581 * sem_ch5.adb (Analyze_Block_Statement): Revert previous change.
4582 * sem_warn.adb (Check_References): Revert previous change.
4584 2017-09-06 Bob Duff <duff@adacore.com>
4586 * exp_util.adb (Is_Displace_Call): Make sure it works for indirect
4587 calls and the like.
4589 2017-09-06 Yannick Moy <moy@adacore.com>
4591 * sem_prag.adb (Analyze_Depends_Global): Reinforce test on object
4592 declarations to only consider valid uses of Global/Depends those on
4593 single concurrent objects.
4595 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
4597 * sem_ch13.adb (Check_Record_Representation_Clause): Give an
4598 error as soon as one of the specified components overlaps the
4599 parent field.
4601 2017-09-06 Arnaud Charlet <charlet@adacore.com>
4603 * sem_prag.ads: minor fix typo in comment.
4605 2017-09-06 Justin Squirek <squirek@adacore.com>
4607 * sem_ch5.adb (Analyze_Block_Statement): Verify a block comes
4608 from source before checking source references.
4609 * sem_warn.adb (Check_References): Add check for internal block
4610 before recursing.
4612 2017-09-06 Vincent Celier <celier@adacore.com>
4614 * make.adb, makeusg.adb, switch-m.adb, switch-m.ads, make_util.adb,
4615 make_util.ads, sinput.adb, sinput.ads, clean.adb, gnatls.adb,
4616 gnatname.adb: Remove the Project Manager from the GNAT tools.
4617 * gcc-interface/Makefile.in: ditto.
4619 2017-09-06 Bob Duff <duff@adacore.com>
4621 * sem_util.ads: Minor comment fix.
4623 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4625 * sem_ch12.adb (Analyze_Associations, case of Formal_Package):
4626 Generate a freeze node for the actual of a formal package, if
4627 the actual is declared in the same unit and has a corresponding
4628 body, to prevent the current instance from being frozen before
4629 the actual is.
4631 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
4633 * sem_ch7.adb (Entity_Table_Size): Change to nearest prime number.

4641 * einfo.ads, einfo.adb (Get_Classwwide_Pragma): New utility,
4642 to retrieve the inherited classwide precondition/postcondition
4643 of a subprogram.
4644 * freeze.adb (Freeze_Entity): Use Get_Classwide_Pragma when
4645 freezing a subprogram, to complete the generation of the
4646 corresponding checking code.
4648 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>
4650 * exp_util.adb (Is_Controlled_Indexing): New routine.
4651 (Is_Displace_Call): Use routine Strip to remove indirections.
4652 (Is_Displacement_Of_Object_Or_Function_Result): Code clean up. Add a
4653 missing case of controlled generalized indexing.
4654 (Is_Source_Object): Use routine Strip to remove indirections.
4655 (Strip): New routine.
4657 2017-09-06 Bob Duff <duff@adacore.com>
4659 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
4660 we include the proper header. Otherwise, we just declare the necessary
4661 things from the capabilities library. This is so we can build on
4662 machines without that library, while still enabling that library.
4663 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
4664 simply return 0 if the library is not present, or not included
4665 in the link.
4667 2017-09-06 Pierre-Marie de Rodat <derodat@adacore.com>
4669 * exp_dbug.adb (Debug_Renaming_Declaration): Do not create an encoding
4670 for renamings that involve function calls in prefix form.
4672 2017-09-06 Bob Duff <duff@adacore.com>
4674 * sem_ch3.adb (Analyze_Subtype_Declaration):
4675 Set Has_Delayed_Freeze on a subtype of an incomplete type.
4677 2017-09-06 Pierre-Marie de Rodat <derodat@adacore.com>
4679 * par_sco.adb (Extend_Statement_Sequence): When the accept statement
4680 has no parameter specification and no entry index, use the entry name
4681 as the end of the generated SCO statement.
4683 2017-09-06 Steve Baird <baird@adacore.com>
4685 * exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
4686 uses of 'Image and related attributes as having side effects in
4687 order to avoid replicating such uses.
4688 * pprint.ads (Expression_Image) Add new generic formal flag
4689 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
4690 (eventually) override the default.
4691 * pprint.adb (Expression_Image) If the new flag is set, then
4692 suppress the ".all" suffix when displaying a dereference whose
4693 prefix is a use of a value-capturing compiler temp of the sort
4694 generated by Expr_Util.Remove_Side_Effects .
4695 * exp_attr.adb, g-catiio.adb, inline.adb, sem_attr.adb, sem_ch13.adb,

4708 * sem_util.adb, sem_util.ads (Within_Protected_Type): Renaming
4709 with slight modification from Is_Subp_Or_Entry_Inside_Protected,
4710 so that applies to any entity.
4712 2017-09-06 Yannick Moy <moy@adacore.com>
4714 * sem_ch3.adb (Derived_Type_Declaration): Use
4715 Incomplete_Or_Partial_View rather than local Find_Partial_View.
4717 2017-09-06 Javier Miranda <miranda@adacore.com>
4719 * g-catiio.ads, g-catiio.adb (Value): Extended to parse an UTC time
4720 following ISO-8861.
4722 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4724 * sem_dim.adb (Analyze_Dimension): In an instance, a type
4725 conversion takes its dimensions from the expression, not from
4726 the context type.
4727 (Dimensions_Of_Operand): Ditto.
4729 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4731 * exp_ch6.adb (Expand_Call_Helper): Do not optimize calls to
4732 null procedures when GNAT coverage is used, so that their (empty)
4733 bodies are properly covered.
4735 2017-09-06 Bob Duff <duff@adacore.com>
4737 * sem_ch13.adb (Resolve_Aspect_Expressions): If
4738 the entity is a type with discriminants, make the discriminants
4739 directly visible in aspect clauses.
4741 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4743 * sem_res.adb (Resolve_Arithmentic_Op): If both operands are
4744 Universal_Real and the context is a floating-point type, resolve
4745 both operands to the target type.
4747 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>
4749 * a-comlin.adb, exp_aggr.adb, exp_ch6.adb, frontend.adb, gnatbind.adb,
4750 sem_ch3.adb, sem_util.adb: Minor reformatting.
4752 2017-09-06 Yannick Moy <moy@adacore.com>
4754 * freeze.adb (Check_Inherited_Conditions): Rewriting
4755 of inherited preconditions and postconditions should only occur
4756 in GNATprove mode, that is, when GNATprove_Mode is True, not to
4757 be confused with SPARK_Mode being On.
4759 2017-09-06 Yannick Moy <moy@adacore.com>
4761 * sem_warn.adb (Check_References): Take into
4762 account possibility of attribute reference as original node.

5043 left-hand side, which are invisible in the righ-hand side and
5044 not retrievable as selected components.
5046 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5048 * sem_util.adb (Needs_One_Formal): The first formal of such a

5088 not visible in the object.
5089 * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
5090 side may be derived from that of the left-hand side (as in the
5091 case of an assignment with a change of representation) so the
5092 discriminant to be used in the retrieval of the value of the
5093 component must be the entity in the type of the right-hand side.

5122 in a set membership is an overloaded enumeration literal, and
5123 the type of the alternative is resolved from a previous one,
5124 replace the entity of the alternative as well as the type,
5125 to prevent inconsistencies between the entity and the type.

5730 2017-05-02 Arnaud Charlet <charlet@adacore.com>
5732 * sem_case.adb: Remove extra spaces in parameter declarations.
5734 2017-05-02 Justin Squirek <squirek@adacore.com>
5736 * usage.adb: Replace space with hyphen ("run time" -> "run-time")
5737 in usage line for new -gnatwE switch.
5739 2017-05-02 Claire Dross <dross@adacore.com>
5741 * a-cofuve.ads (Remove): Remove unnecessary
5742 conditions in precondition.
5744 2017-05-02 Vasiliy Fofanov <fofanov@adacore.com>
5746 * a-stream.ads, exp_imgv.adb, sem_ch10.adb,
5747 sem_attr.adb, s-finmas.ads, osint.adb: Minor typo fix.
5749 2017-05-02 Justin Squirek <squirek@adacore.com>
5751 * sem_ch4.adb (Analyze_Case_Expression): Add check for valid
5752 alternative expression.
5753 * sem_res.adb (Resolve_Case_Expression): Ditto.
5755 2017-05-02 Ed Schonberg <schonberg@adacore.com>
5757 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
5758 Refine predicate for the case where the primitive operation
5759 is a renaming of equality. An overriding operation that is
5760 a user-defined renaming of predefined equality inherits its
5761 slot from the overridden operation. Otherwise it is treated
5762 as a predefined op and occupies the same predefined slot as
5763 equality. A call to it is transformed into a call to its alias,
5764 which is the predefined equality. A dispatching call thus uses
5765 the proper slot if operation is further inherited and called
5766 with class-wide arguments.
5768 2017-05-02 Justin Squirek <squirek@adacore.com>
5770 * errout.adb (Set_Msg_Text): Add a case to switch the message
5771 type when the character '[' is detected signifying a warning
5772 about a run-time exception.
5773 * opt.ads Add a new Warning_Mode value for new switch
5774 * switch-b.adb (Scan_Binder_Switches): Add case for the binder
5775 to handle new warning mode
5776 * usage.adb (Usage): Add usage entry for -gnatwE
5777 * warnsw.adb (Set_Warning_Switch): Add case for the new switch
5779 2017-05-02 Ed Schonberg <schonberg@adacore.com>
5781 * sem_prag.adb (Process_Conversion): Reject an intrinsic operator
5782 declaration that operates on some fixed point type.
5784 2017-05-02 Justin Squirek <squirek@adacore.com>
5786 * a-crbtgo.adb, s-taasde.adb: Remove unused use-type clauses.

5795 expression (Analyze_If_Expression): Add check for valid condition
5796 * sem_eval.adb (Eval_Case_Expression): Add check for error posted
5797 on case-expression

5799 condition and then-expression.
5801 2017-05-02 Ed Schonberg <schonberg@adacore.com>
5803 * exp_ch3.adb (Build_Initialization_Call): Generate a null
5804 statement if the initialization call is a null procedure, as
5805 can happen with a controlled type with no explicit Initialize
5806 procedure, or an array of such.
5807 * exp_ch7.adb (Process_Object_Declaration): For a type with
5808 controlled components that has a trivial Initialize procedure,
5809 insert declaration for finalization counter after object
5810 declaration itself.
5811 (Make_Deep_Array_Body, Build_Initialize_statements): Do not create
5812 finalization block and attendant declarations if component has
5813 a trivial Initialize procedure.
5814 (Make_Init_Call): Do not generate a call if controlled type has
5815 a trivial Initialize procedure.
5817 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
5819 * g-forstr.ads (Data): Move Format component last.
5820 * g-forstr.adb ("+"): Adjust for above change.
5821 * g-rewdat.ads (Buffer): Move Buffer, Current, Pattern and Value last.
5822 * g-sechas.ads (Context): Move Key last.
5823 * g-socket.ads (Service_Entry_Type): Move Aliases last.
5824 * s-fileio.adb (Temp_File_Record): Move Name last.
5825 * s-regexp.adb (Regexp_Value): Move Case_Sensitive last.
5826 * xr_tabls.ads (Project_File): Move Src_Dir and Obj_Dir last.
5828 2017-05-02 Jerome Lambourg <lambourg@adacore.com>
5830 * bindusg.adb, bindgen.adb, gnatbind.adb, opt.ads: Remove the -nognarl
5831 switch introduced recently. finally not needed.
5833 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
5835 * sem_ch6.adb (Analyze_Null_Procedure): Set the
5836 Corresponding_Body link for a null procedure declaration.
5838 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
5840 * atree.h (Flag290): Add missing terminating parenthesis.
5841 * einfo.adb (Is_Class_Wide_Clone): Use Flag290.
5842 (Set_Is_Class_Wide_Clone): Likewise.
5843 * einfo.ads (Is_Class_Wide_Clone): Likewise.
5845 2017-05-02 Gary Dismukes <dismukes@adacore.com>
5847 * checks.ads (Null_Exclusion_Static_Checks): Add Boolean
5848 parameter Array_Comp to indicate the case of an array object
5849 with null-excluding components.
5850 * checks.adb (Null_Exclusion_Static_Checks):
5851 Call Compile_Time_Constraint_Error instead of
5852 Apply_Compile_Time_Constraint_Error in the component case. Also
5853 call that when Array_Comp is True, with an appropriate warning for
5854 the array component case. Only create an explicit initialization
5855 by null in the case of an object of a null-excluding access type
5856 (and no longer do that in the component case).
5857 * sem_ch3.adb (Check_Component): Add a Boolean parameter
5858 Array_Comp defaulted to False. Pass Empty for the Comp
5859 actual when calling Null_Exclusion_Static_Checks in the case
5860 where Comp_Decl matches Object_Decl, because we don't have a
5861 component in that case. In the case of an object or component
5862 of an array type, pass True for Array_Comp on the recursive call
5863 to Check_Component.
5865 2017-05-02 Bob Duff <duff@adacore.com>
5867 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
5868 compute the linux priority from the Ada priority. Call this everywhere
5869 required. In particular, the previous version was not doing this
5870 computation when setting the ceiling priority in various places. It
5871 was just converting to C.int, which results in a ceiling that is off
5872 by 1.
5874 2017-05-02 Ed Schonberg <schonberg@adacore.com>
5876 * sem_ch3.adb: Comment predicate inheritance.
5878 2017-05-02 Tristan Gingold <gingold@adacore.com>
5880 * s-trasym.ads: Add comment.
5882 2017-05-02 Bob Duff <duff@adacore.com>
5884 * sem_elab.adb, sem_elab.ads: Minor comment fixes.
5885 * sem_ch4.adb: Minor reformatting.

5890 2017-05-02 Ed Schonberg <schonberg@adacore.com>
5892 * exp_ch9.adb (Discriminated_Size): Moved to sem_util.
5893 * sem_util.ads, sem_util.adb (Discriminated_Size): Predicate moved
5894 here from exp_ch9, to recognize objects whose creation requires
5895 dynamic allocation, so that the proper warning can be emitted
5896 when restriction No_Implicit_Heap_Allocation is in effect.
5897 * sem_ch3.adb (Analyze_Object_Declaration): Use Discriminated_Size
5898 to emit proper warning when an object that requires dynamic
5899 allocation is declared.
5901 2017-05-02 Tristan Gingold <gingold@adacore.com>
5903 * s-trasym.ads, s-trasym.adb (Enable_Cache): New.
5905 2017-05-02 Ed Schonberg <schonberg@adacore.com>
5907 * sem_ch4.adb (Find_Equality_Types, Try_One_Interp): The same relaxed
5908 visibility rules for equality operators that apply within an
5909 instantiation apply within an inlined body.
5910 * sem_type.adb (Add_One_Interp): ditto.
5912 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
5914 * sem_prag.adb (Analyze_Pragma): Forbid pragma Contract_Cases on null
5915 procedures.
5917 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
5919 * snames.ads-tmpl
5920 (Name_Assume, Name_Attribute_Definition, Name_Loop_Optimize,
5921 Name_No_Tagged_Streams): Move to regular pragmas. Add
5922 placeholders for Default_Scalar_Storage_Order, Dispatching_Domain,
5923 and Secondary_Stack_Size.
5924 (Pragma_Id): Move Pragma_Assume,
5925 Pragma_Attribute_Definition, Pragma_Loop_Optimize and
5926 Pragma_No_Tagged_Streams to second part.
5928 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
5930 * exp_attr.adb: Minor reformatting.
5932 2017-05-02 Ed Schonberg <schonberg@adacore.com>
5934 * sem_ch4.adb (Analyze_Selected_Component): Improve error
5935 detection for illegal references to private components or
5936 operations of a protected type in the body of the type.
5938 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
5940 * opt.ads: Add missing GNAT markers in comments.
5941 * opt.adb (Set_Opt_Config_Switches): Do not override earlier
5942 settings of Optimize_Alignment at the end.
5944 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
5946 * checks.adb (Apply_Constraint_Check): Do not apply
5947 a discriminant check when the associated type is a constrained
5948 subtype created for an unconstrained nominal type.
5949 * exp_attr.adb: Minor reformatting.
5951 2017-05-02 Bob Duff <duff@adacore.com>
5953 * sem_ch3.adb (OK_For_Limited_Init_In_05): Handle correctly
5954 the N_Raise_Expression case.
5955 * sem_ch6.adb (Check_Limited_Return): Minor: clarify comment,
5956 and add assertions.
5958 2017-05-02 Yannick Moy <moy@adacore.com>
5960 * exp_ch4.adb (Expand_N_Op_Ne): Do not bump parenthese level and
5961 optimize length comparison in GNATprove mode.
5962 * exp_spark.adb (Expand_SPARK_Op_Ne): New function to rewrite
5963 operator /= into negation of operator = when needed.
5964 (Expand_SPARK): Call new
5965 function to expand operator /=.
5967 2017-05-02 Ed Schonberg <schonberg@adacore.com>
5969 * exp_fixd.adb (Expand_Divide_Fixed_By_Fixed_Giving_Fixed):
5970 Simplify the expression for a fixed-fixed division to remove
5971 divisions by constants whenever possible, as an optimization
5972 for restricted targets.
5974 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
5976 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
5978 2017-05-02 Bob Duff <duff@adacore.com>
5980 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
5981 to find primitive ops, instead of using an Identifier that will
5982 later be looked up. This is necessary because these ops are not
5983 necessarily visible at all places where we need to call them.
5984 * exp_util.ads: Minor comment fix.
5986 2017-05-02 Ed Schonberg <schonberg@adacore.com>
5988 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
5989 references are fully conformant if they are both expansions
5990 of the discriminant of a protected type, within one of the
5991 protected operations. One occurrence may be expanded into a
5992 constant declaration while the other is an input parameter to
5993 the corresponding generated subprogram.
5995 2017-05-02 Justin Squirek <squirek@adacore.com>
5997 * sem_ch3.adb (Check_For_Null_Excluding_Components): Created for
5998 recursivly searching composite-types for null-excluding access
5999 types and verifying them.
6000 (Analyze_Object_Declaration): Add a
6001 call to Check_Null_Excluding_Components for static verification
6002 of non-initialized objects.
6003 * checks.adb, checks.ads (Null_Exclusion_Static_Checks): Added
6004 a parameter for a composite-type's component and an extra case
6005 for printing component information.
6007 2017-05-02 Yannick Moy <moy@adacore.com>
6009 * sem_ch10.adb (Analyze_Subunit): Take
6010 configuration pragma into account when restoring appropriate
6011 pragma for analysis of subunit.
6013 2017-05-02 Justin Squirek <squirek@adacore.com>
6015 * s-tasren.adb, s-tasini.adb, s-taprop-linux.adb,
6016 s-mudido-affinity.adb,, a-exetim-posix.adb, a-direio.adb,
6017 g-socket.adb, s-taenca.adb, s-fileio.adb: Remove unused use-type
6018 clauses from the runtime.
6020 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
6022 * freeze.adb (Check_Component_Storage_Order): Do not treat bit-packed
6023 array components specially.
6025 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6027 * sem_ch8.adb (Premature_Usage): If the premature usage of
6028 an entity is as the expression in its own object decaration,
6029 rewrite the reference as Any_Id to prevent cascaded errors or
6030 compiler loops when such an entity is used in an address clause.
6032 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
6034 * gcc-interface/decl.c (components_to_record): Add missing guard.
6036 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
6038 * gcc-interface/decl.c (components_to_record): Add more comments.
6039 Put back pending fields onto the regular list if the misalignment
6040 happens to cancel itself.
6042 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6044 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
6045 controlling actual in a prefixed call, preserve the original node
6046 information if the prefix itself has been rewritten, for ASIS use.
6048 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6050 * exp_ch6.adb (Insert_Post_Call_Actions):
6051 Code clean up. Insert the post-call actions after an enclosing
6052 procedure call when N denotes a function call and appears as an
6053 actual parameter in the procedure call.
6055 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6057 * freeze.adb (Check_Component_Storage_Order): If there is a clause
6058 for the component, also reject the attribute if the component
6059 doesn't end on a byte boundary and its scalar storage order is
6060 different from that of the enclosing record type.
6062 2017-04-28 Javier Miranda <miranda@adacore.com>
6064 * atree.ads (Info_Messages): Removed.
6065 (Warning_Info_Messages): New counter.
6066 (Report_Info_Messages): New counter.
6067 * err_vars.ads Update documentation.
6068 * errout.adb (Delete_Warning_And_Continuations): Update
6069 Info_Message occurrences.
6070 (Error_Msg_Internal): Update Info_Message occurrences.
6071 (Delete_Warning): Update Info_Message occurrences.
6072 (Write_Error_Summary): Update Info_Message occurrences.
6073 (Output_Messages): Update Info_Message occurrences.
6074 (To_Be_Removed): Update Info_Message occurrences.
6075 (Reset_Warnings): Update Info_Message occurrences.
6076 * errutil.adb (Error_Msg): Update Info_Message occurrences.

6080 (Compilation_Errors): Update Info_Message_Occurences.
6082 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6084 * exp_ch3.adb (Build_Init_Statements): Likewise on Nam.
6085 * freeze.adb (Check_Component_Storage_Order): And on Comp_Byte_Aligned.
6086 * sem_aggr.adb (Resolve_Record_Aggregate): Initialize Box_Node.
6087 * sem_attr.adb (Loop_Entry): Initialize Encl_Loop.
6088 * sem_ch12.adb (Build_Operator_Wrapper): Add pragma Warnings on Expr.
6089 * sem_ch13.adb (Validate_Address_Clauses): Initialize Y_Alignment and
6090 Y_Size.

6092 * sem_prag.adb (Analyze_Pragma): Add pragma Warnings on Str.
6094 2017-04-28 Bob Duff <duff@adacore.com>
6096 * sem_util.ads, sem_util.adb (Might_Raise): New function
6097 that replaces Is_Exception_Safe, but has the opposite
6098 sense. Is_Exception_Safe was missing various cases -- calls inside
6099 a pragma Debug, calls inside an 'if' or assignment statement,
6100 etc. Might_Raise now walks the entire subtree looking for things
6101 that can raise.
6102 * exp_ch9.adb (Is_Exception_Safe): Remove.
6103 (Build_Protected_Subprogram_Body): Replace call to
6104 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
6105 constants where possible).
6106 * exp_ch7.adb: Rename Is_Protected_Body -->
6107 Is_Protected_Subp_Body. A protected_body is something different
6108 in the grammar.
6110 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6112 * inline.adb (Expand_Inlined_Call): Initialize Targ1 variable.

6120 * sem_ch4.adb (List_Operand_Interps): Add pragma Warnings on variable.
6121 * sem_ch5.adb (Analyze_Assignment): Initialize Save_Full_Analysis.
6122 (Analyze_Exit_Statement): Initialize Scope_Id variable.
6123 (Analyze_Iterator_Specification): Initialize Bas variable.
6124 * sem_ch9.adb (Allows_Lock_Free_Implementation): Initialize
6125 Error_Count (Satisfies_Lock_Free_Requirements): Likewise.
6126 (Analyze_Accept_Statement): Initialize Task_Nam.
6128 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6130 * checks.adb (Install_Primitive_Elaboration_Check):
6131 Do not generate an elaboration check if all checks have been
6132 suppressed.
6134 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6136 * sem_ch13.adb (Analyze_Aspect_Specifications, case
6137 Interrupt_Handler and Attach_Handler): Generate reference
6138 to protected operation to prevent spurious warnings about
6139 unreferenced entities. Previous scheme failed with style checks
6140 enabled.
6142 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6144 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
6145 that follows an expression function must not be relocated to
6146 the generated body, because it applies to the code that follows.
6148 2017-04-28 Gary Dismukes <dismukes@adacore.com>
6150 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
6151 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
6152 code that might violate the more stringent checking for 'Access
6153 introduced in Ada 2005.
6155 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6157 * a-cforse.adb: minor style fix in comment.
6159 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6161 * exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also
6162 initialize Block_Decls variable.
6163 (Expand_Entry_Barrier): Add pragma Warnings on Func_Body variable.
6164 (Build_Dispatching_Requeue): Add pragma Warnings on Op variable.
6165 * exp_disp.adb (Expand_Interface_Actuals): Initialize
6166 Formal_DDT and Actual_DDT variables.
6167 (Expand_Interface_Thunk): Initialize Iface_Formal.
6168 (Make_DT): Initialize Size_Comp.
6169 (Make_Select_Specific_Data_Table): Initialize Decls.
6170 * exp_dist.adb (Add_RACW_Primitive_Declarations_And_Bodies):
6171 Also initialize more RPC_Receiver_* variables.
6172 (Build_To_Any_Function): Initialize Cstr_Formal.
6173 * exp_prag.adb (Expand_Pragma_Contract_Cases): Initialize Msg_Str.
6175 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6177 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
6178 node between access types, freeze the designated type as well,
6179 so that dispatch table pointers are created in the proper scope,
6180 and not in the constructed body of the expression function.
6182 2017-04-28 Bob Duff <duff@adacore.com>
6184 * alloc.ads (Nodes_Initial): Go back to previous value. The large
6185 value makes large compilations faster, but small compilations slower.
6187 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6189 * sem_util.adb: minor typos in Is_Child_Or_Sibling.
6191 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6193 * erroutc.adb (Compilation_Errors): Do not consider info messages
6194 as suitable warnings when warnings must be treated as errors.
6195 * sem_ch7.adb (Analyze_Package_Specification): Do not consider
6196 internally-generated packages when outputting completion
6197 information.
6198 * errout.adb (Output_Messages): Do not consider info messages as
6199 suitable warnings when warnings must be treated as errors.
6200 * errutil.adb (Finalize): Do not consider info messages as
6201 suitable warnings when warnings must be treated as errors.
6203 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6205 * warnsw.ads: Minor fix for incorrect wording in comment.
6207 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6209 * sem_res.adb (In_Instance_Code): New predicate in
6210 Valid_Conversion, to determine whether a type conversion appears
6211 as (or within) an actual for a formal object. Type conversions
6212 in instances are not rechecked in Valid_Conversion because
6213 visibility changes between generic location andi instance may
6214 lead to spurious errors, but conversions within an actual must be
6215 fully checked, and they are not fully resolved when pre-analyzing
6216 the actuals.
6218 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6220 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
6221 New_Copy_Tree instead of Relocate_Node as any subsequent copies
6222 of the relocated node will have mangled Parent pointers.
6223 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
6224 tables used in conjunction with entity and itype replication.
6225 (Visit_Entity): Rewrite the restriction on which entities
6226 require duplication. The restriction now includes all types.

6270 problematic placement of specific sorts of fields.
6272 2017-04-27 Bob Duff <duff@adacore.com>
6274 * errout.adb, exp_aggr.adb, exp_attr.adb, exp_code.adb, fname.adb,

6279 * sem_intr.adb, sem_res.adb, sem_util.adb, sem_warn.adb, sprint.adb:
6280 For efficiency, cache results of Is_Internal_File_Name and
6281 Is_Predefined_File_Name in the Units table. This avoids a lot
6282 of repeated text processing.
6284 2017-04-27 Emmanuel Briot <briot@adacore.com>
6286 * g-comlin.adb (Sort_Sections): remove useless test.
6288 2017-04-27 Claire Dross <dross@adacore.com>
6290 * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
6291 allow the use of regular equality over elements in contracts.
6292 (Formal_Model): Ghost package containing model functions that are
6293 used in subprogram contracts.
6294 (Current_To_Last): Removed, model functions should be used instead.
6295 (First_To_Previous): Removed, model functions should be used instead.
6296 (Strict_Equal): Removed, model functions should be used instead.
6297 (No_Overlap): Removed, model functions should be used instead.
6298 (Equivalent_Keys): Functions over cursors are removed. They were
6299 awkward with explicit container parameters.
6300 * a-cforse.adb, a-cforse.ads (=): Generic parameter removed to
6301 allow the use of regular equality over elements in contracts.
6302 (Formal_Model): Ghost package containing model functions that

6311 * gnat1drv.adb: Code cleanup.
6313 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6315 * exp_util.adb (Replace_Entity): The prefix of a 'Result
6316 attribute reference in a post- condition is the subprogram to
6317 which the condition applies. If the condition is inherited
6318 by a type extension, the prefix becomes a reference to the
6319 inherited operation, but there is no need to create a wrapper
6320 for this operation, because 'Result is expanded independently
6321 when elaborating the postconditions.
6323 2017-04-27 Bob Duff <duff@adacore.com>
6325 * sinput.adb: Minor code cleanup.
6326 * namet.adb (Append): Create faster versions of
6327 Append(String) and Append(Name_Id) by using slice assignment
6328 instead of loops.
6329 * sem_util.adb (In_Instance): Speed this up by removing
6330 unnecessary tests; Is_Generic_Instance is defined for all
6331 entities.
6332 * sem_util.ads, sem_util.adb (In_Parameter_Specification):
6333 Remove unused function.
6334 * alloc.ads (Nodes_Initial): Use a much larger value, because
6335 the compiler was spending a lot of time copying the nodes table
6336 when it grows. This number was chosen in 1996, so is rather out
6337 of date with current memory sizes. Anyway, it's virtual memory.
6338 Get rid of Orig_Nodes_...; use Node_... instead.
6339 * atree.adb (Lock): Do not release the Nodes tables; it's a
6340 waste of time.
6341 Orig_Nodes_ ==> Nodes_
6342 * nlists.adb: Orig_Nodes_ ==> Nodes_
6343 * g-table.adb: Remove unused "with" clause.
6344 * g-table.ads, table.ads: Remove Big_Table_Type, which should
6345 not be used by clients.
6346 * g-dyntab.adb (Last_Allocated): New function
6347 to encapsulate T.P.Last_Allocated, which I'm thinking of changing.

6366 and Optional.
6367 * par-ch3.adb (P_Declarative_Items): Merge the processing for
6368 tokens function, not, overriding, and procedure.
6369 * sem_ch6.adb (Fully_Conformant_Expressions): Merge the processing
6370 for qualified expressions, type conversions, and unchecked
6371 type conversions.

6382 is in effect.
6384 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6386 * exp_disp.adb (Build_Class_Wide_Check): New subsidiary
6387 of Expand_Dispatching_Call. If the denoted subprogram has a
6388 class-wide precondition, this is the only precondition that
6389 applies to the call, rather that the class-wide preconditions
6390 that may apply to the body that is executed. (This is specified
6391 in AI12-0195).
6393 2017-04-27 Yannick Moy <moy@adacore.com>
6395 * gnat1drv.adb (Adjust_Global_Switches): Issue
6396 a warning in GNATprove mode if the runtime library does not
6397 support IEEE-754 floats.
6399 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6401 * sem_prag.adb (Inherit_Class_Wide_Pre): If the parent operation
6402 is itself inherited it does not carry any contract information,
6403 so examine its parent operation which is its Alias.
6405 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6407 * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
6408 prefix can be an object reference in which case Obj'Image (X)
6409 can only be interpreted as an indexing of the parameterless
6410 version of the attribute.
6411 * par-ch4.adb (P_Name): An attribute reference can be the prefix of
6412 an indexing or a slice operation if the attribute does not require
6413 parameters. In Ada2012 'Image also belongs in this category,
6414 and A'Image (lo .. hi) is legal and must be parsed as a slice.
6416 2017-04-27 Yannick Moy <moy@adacore.com>
6418 * exp_ch4.adb: Minor reformatting.
6419 * gnat1drv.adb (Adjust_Global_Switches): When in GNATprove mode,
6420 disable the CodePeer and C generation modes. Similar to the
6421 opposite actions done in CodePeer mode.

6441 elaboration check.
6443 2017-04-27 Bob Duff <duff@adacore.com>
6445 * g-dyntab.ads, g-dyntab.adb, g-table.ads: Remove incorrect assertion.
6446 If the table grows and then shrinks back to empty, we won't necessarily
6447 point back to the empty array. Code cleanups.
6448 * sinput.ads: Add 'Base to Size clause to match the declared
6449 component subtypes.
6451 2017-04-27 Claire Dross <dross@adacore.com>

6474 of equivalence on functional maps.
6475 * a-cfdlli.adb, a-cfdlli.ads (Formal_Model.P) Disable handling

6480 * exp_ch9.adb (Expand_Entry_Barrier): Code
6481 cleanup. Do not perform the optimization which removes the

6500 * g-dyntab.ads, g-dyntab.adb: Default for Table_Low_Bound.
6501 Rename Empty --> Empty_Table_Ptr, and don't duplicate code for it.
6502 Free renames Init, since they do the same thing.
6503 * g-table.ads: Default for Table_Low_Bound.
6504 * table.ads: Default for Table_Low_Bound, Table_Initial, and
6505 Table_Increment.

6551 (Move, Release_Threshold).
6552 * g-table.ads, g-table.adb: This is now just a thin wrapper
6553 around g-dyntab.ads/g-dyntab.adb. Add functionality supported
6554 or needed by other tables packages (Save, Restore).
6555 * table.ads, table.adb: This is now just a thin wrapper around
6556 * g-table.ads/g-table.adb.
6557 * namet.h, scos.h, uintp.h: These files are reaching into the
6558 private data of some instances of g-table, whose names changed,
6559 so the above change requires some adjustment here. It now uses
6560 public interfaces.

6604 * freeze.adb (Build_Inherited_Condition_Pragmas): New procedure,
6605 subsidiary of Check_Inherited_Conditions, to build pragmas for an
6606 operation whose ancestor has classwide pre/postconditions. This

6609 an inherited operation.
6610 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity):
6611 Improve placement of error message for inherited classwide
6612 conditions that become illegal on type derivation.

6638 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6640 * sem_dim.adb (Analyze_Dimension_Object_Declaration): There is
6641 no dimensionality error if the subtype of the expression is
6642 identical to the nominal subtype in the declaration, even though
6643 the expression itself may have been constant-folded and lack a
6644 dimension vector.
6645 * sem_dim.ads: Add comments on setting of dimension vectors and

6698 On unbounded containers, return the maximal capacity.
6699 (Current_To_Last): Removed, model functions should be used instead.

6701 (Append): Default parameter value replaced
6702 by new wrapper to allow more precise contracts.
6703 (Insert): Subprogram restored, it seems it was useful to users even if
6704 it is inefficient.
6705 (Delete): Subprogram restored, it seems it was useful to users even if
6706 it is inefficient.
6707 (Prepend): Subprogram restored, it seems it was useful to users even
6708 if it is inefficient.
6709 (Delete_First): Subprogram restored, it seems it
6710 was useful to users even if it is inefficient. (Delete_Last):
6711 Default parameter value replaced by new wrapper to allow more
6712 precise contracts.

6732 Default parameter value replaced by new wrapper to allow more
6733 precise contracts.
6734 (Generic_Sorting.Merge): Subprogram restored.
6735 (Vector): Do not reuse formal vectors, as it is no longer possible
6736 to supply them with an equality function over elements.
6738 2017-04-27 Bob Duff <duff@adacore.com>
6740 * g-dyntab.adb (Release): When allocating the new
6741 table, use the correct slice of the old table to initialize it.

6757 * sem_util.adb, sem_util.ads (Build_Class_Wide_Clone_Body):
6758 Build body of subprogram that has a class-wide condition that
6759 contains calls to other primitives.
6760 (Build_Class_Wide_Clone_Call); Build a call to the common
6761 class-wide clone of a subprogram with classwide conditions. The
6762 body of the subprogram becomes a wrapper for a call to the
6763 clone. The inherited operation becomes a similar wrapper to which
6764 modified conditions apply, and the call to the clone includes
6765 the proper conversion in a call the parent operation.
6766 (Build_Class_Wide_Clone_Decl (Spec_Id : Entity_Id): For a
6767 subprogram that has a classwide condition that contains calls to
6768 other primitives, build an internal subprogram that is invoked
6769 through a type-specific wrapper for all inherited subprograms
6770 that may have a modified condition.
6771 * sem_prag.adb (Check_References): If subprogram has a classwide
6772 condition, create entity for corresponding clone, to be invoked
6773 through wrapper subprograns.
6774 (Analyze_Pre_Post_Condition_In_Decl_Part): Do not emit error
6775 message about placement if pragma isi internally generated.
6776 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): If subprogram has
6777 a classwide clone, build body of clone as copy of original body,
6778 and rewrite original body as a wrapper as a wrapper for a call to
6779 the clone, so that it incorporates the original pre/postconditions
6780 of the subprogram.
6781 * freeze.adb (Check_Inherited_Conditions): For an inherited
6782 subprogram that inherits a classwide condition, build spec and
6783 body of corresponding wrapper so that call to inherited operation
6784 gets the modified conditions.
6785 * contracts.adb (Analyze_Contracts): If analysis of classwide
6786 condition has created a clone for a primitive operation, analyze
6787 declaration of clone.

6805 * sem_ch13.adb (Analyze_Attribute_Definition_Clause
6806 [Attribute_Address]): Call Set_Address_Taken when ignoring rep

6808 before removing it from the tree.
6810 2017-04-27 Yannick Moy <moy@adacore.com>
6812 * exp_util.ads, exp_util.adb (Evaluate_Name): Force evaluation
6813 of expression being qualified, when not an object name, or else
6814 evaluate the underlying name.
6816 2017-04-27 Jerome Lambourg <lambourg@adacore.com>
6818 * bindusg.adb, bindgen.adb, gnatbind.adb, opt.ads: add -nognarl switch.

6825 global references.
6826 (Process_Component_List_For_Finalization): Correct calls to
6827 Process_Component_For_Finalize to take Num_Comps as a parameter.
6829 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
6831 * sem_ch8.adb (Find_Direct_Name): Account for the case where
6832 a use-visible entity is defined within a nested scope of an
6833 instance when giving priority to entities which were visible in
6834 the original generic.
6835 * sem_util.ads, sem_util.adb (Nearest_Enclosing_Instance): New routine.
6837 2017-04-27 Tristan Gingold <gingold@adacore.com>
6839 * raise-gcc.c: Don't use unwind.h while compiling
6840 for the frontend, but mimic host behavior.
6842 2017-04-27 Javier Miranda <miranda@adacore.com>
6844 * sem_ch3.adb (Build_Discriminated_Subtype):
6845 Propagate Has_Pragma_Unreferenced_Objects to the built subtype.
6847 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
6849 * sem_prag.adb (Analyze_Global_Item):
6850 Do not consider discriminants because they are not "entire
6851 objects". Remove the discriminant-related checks because they are
6852 obsolete.
6853 (Analyze_Input_Output): Do not consider discriminants
6854 because they are not "entire objects".
6856 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6858 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Do not
6859 perform check if the current scope does not come from source,
6860 as is the case for a rewritten task body, because check has
6861 been performed already, and may not be doable because of changed
6862 visibility.
6864 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
6866 * a-cofuse.adb, a-cfdlli.adb, a-cofuse.ads, a-cfdlli.ads, a-cofuve.adb,

6868 Minor reformatting.
6870 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6872 * sem_ch4.adb (Analyze_Call): If the return type of a function
6873 is incomplete in an context in which the full view is available,
6874 replace the type of the call by the full view, to prevent spurious
6875 type errors.
6876 * exp_disp.adb (Check_Premature_Freezing): Disable check on an
6877 abstract subprogram so that compiler does not reject a parameter
6878 of a primitive operation of a tagged type being frozen, when
6879 the untagged type of that parameter cannot be frozen.
6881 2017-04-27 Bob Duff <duff@adacore.com>

6907 Code reformatting.
6909 2017-04-27 Pierre-Marie de Rodat <derodat@adacore.com>
6911 * gcc-interface/utils.c (gnat_type_for_size): Set
6912 TYPE_ARTIFICIAL on created types.
6914 2017-04-27 Claire Dross <dross@adacore.com>
6916 * a-cfdlli.adb, a-cfdlli.ads (Formal_Model): Adapt to
6917 modifications in functional containers.
6918 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
6919 to improve readablity. Subprograms are separated between basic
6920 operations, constructors and properties. Universally quantified
6921 formulas in contracts are factorized in independant functions
6922 with a name and a comment. Names of parameters are improved.
6924 2017-04-27 Gary Dismukes <dismukes@adacore.com>
6926 * exp_spark.adb, sem_elab.adb: Minor reformatting and typo fix.
6928 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
6930 * sem_res.adb (Resolve_Type_Conversion): Do not
6931 install a predicate check here since this is already done during
6932 the expansion phase. Verify whether the operand satisfies the
6933 static predicate (if any) of the target type.
6934 * sem_ch3.adb (Analyze_Object_Declaration): Do
6935 not install a predicate check if the object is initialized by
6936 means of a type conversion because the conversion is subjected
6937 to the same check.
6939 2017-04-27 Tristan Gingold <gingold@adacore.com>
6941 * raise.c (__gnat_builtin_longjmp): Remove.
6942 (__gnat_bracktrace):
6943 Add a dummy definition for the compiler (__gnat_eh_personality,
6944 __gnat_rcheck_04, __gnat_rcheck_10) (__gnat_rcheck_19,

6958 * gcc-interface/Makefile.in: No more variants for a-exexpr.adb and
6959 a-except.ad[sb].
6960 * gcc-interface/Make-lang.in: Add support for backend zcx exceptions
6961 in gnat1 and gnatbind.
6962 * gnat1, gnatbind: link with raise-gcc.o, a-exctra.o, s-addima.o,
6963 s-excmac.o, s-imgint.o, s-traceb.o, s-trasym.o, s-wchstw.o
6964 * s-excmac.ads, s-excmac.adb: Copy of variants.

6975 formulas in contracts are factorized in independant functions
6976 with a name and a comment. Names of parameters are improved.
6978 2017-04-27 Gary Dismukes <dismukes@adacore.com>
6980 * exp_spark.adb, sem_elab.adb: Minor reformatting and typo fix.
6982 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
6984 * sem_res.adb (Resolve_Type_Conversion): Do not

7008 Ada95.
7010 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7012 * exp_ch7.adb (Establish_Transient_Scope): Rewrite
7013 the loop which detects potential enclosing transient scopes. The
7014 loop now terminates much earlier as transient scopes are bounded
7015 by packages and subprograms.
7017 2017-04-27 Claire Dross <dross@adacore.com>
7019 * a-cfdlli.adb, a-cfdlli.ads (=): Generic parameter removed to
7020 allow the use of regular equality over elements in contracts.
7021 (Cursor): Type is now public so that it can be used in
7022 model functions.
7023 (Formal_Model): Ghost package containing
7024 model functions that are used in subprogram contracts.
7025 (Current_To_Last): Removed, model functions should be used
7026 instead.
7027 (First_To_Previous): Removed, model functions should
7028 be used instead.
7029 (Strict_Equal): Removed, model functions
7030 should be used instead.
7031 (Append): Default parameter value
7032 replaced by new wrapper to allow more precise contracts.

7047 for object declarations.
7048 (Expand_SPARK_N_Object_Declaration): New routine.

7050 Default_Initial_Condition procedure of a type under the SPARK
7051 elaboration checks umbrella.
7053 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7055 * sem.adb (Analyze): Diagnose an illegal iterated component
7056 association.

7060 2017-04-27 Bob Duff <duff@adacore.com>
7062 * adaint.c (__gnat_get_current_dir): Return 0 in length if
7063 getcwd fails.
7064 * a-direct.adb, g-dirope.adb, osint.adb, s-os_lib.adb: Raise
7065 exception if getcwd failed.

7072 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7074 * debug.adb Change the documentation of switch -gnatd.s.
7075 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
7076 to manage the secondary stack when an enclosing scope already
7077 performs this functionality (aka relaxed management). Switch
7078 -gnatd.s may be used to force strict management in which case
7079 the block will manage the secondary stack unconditionally. Add
7080 a guard to stop the traversal when encountering a package or a
7081 subprogram scope.
7083 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7085 * sem_res.adb (Resolve_Call): Refine further the handling of
7086 limited views of return types in function calls. If the function
7087 that returns a limited view appears in the current unit,
7088 we do not replace its type by the non-limited view because
7089 this transformation is performed int the back-end. However,
7090 the type of the call itself must be the non-limited view, to
7091 prevent spurious resolution errors.
7093 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7095 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
7096 Removed, proposed implementation using generics for class-wide
7097 preconditions proved impractical.
7098 (Class_Wide_Clone): New attribute of subprogram. Designates
7099 subprogram created for primitive operations with class-wide
7100 pre/postconditions that contain calls to other primitives. The
7101 clone holds the body of the original primitive, but the
7102 pre/postonditions do not apply to it. The original body is
7103 rewritten as a wrapper for a call to the clone.
7104 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
7105 the flag is set, no code for the corresponding pre/postconditions
7106 is inserted into its body.
7108 2017-04-27 Bob Duff <duff@adacore.com>
7110 * exp_prag.adb, par-prag.adb, sem_ch13.adb: Ignore

7121 * a-cofuse.ads (Add): Adapt to the new API of Base.Add.
7122 (Remove): New function that removes an element from a set.
7123 * a-cofuve.ads (Add): Adapt to the new API of Base.Add.
7124 (Remove): New function that removes an element from a sequence.
7125 (Insert): New function that adds anywhere in a sequence.

7139 Unreferenced.
7141 2017-04-27 Justin Squirek <squirek@adacore.com>
7143 * cstand.adb (Create_Standard): Correctly set

7155 containers.
7156 * a-cofuma.ads, a-cofuma.adb (Ada.Containers.Functional_Maps): New
7157 child of Ada.Containers. It provides functional indefinite unbounded
7158 maps which can be used as high level models for specification
7159 of data structures.
7160 * a-cofuse.ads, a-cofuse.adb (Ada.Containers.Functional_Sets): New
7161 child of Ada.Containers. It provides functional indefinite unbounded
7162 sets which can be used as high level models for specification
7163 of data structures.
7164 * a-cofuve.ads, a-cofuve.adb (Ada.Containers.Functional_Vectors): New
7165 child of Ada.Containers. It provides functional indefinite unbounded
7166 vectors which can be used as high level models for specification
7167 of data structures.
7168 * Makefile.rtl: Add new packages.
7169 * impunit.adb: Add new packages.
7171 2017-04-27 Gary Dismukes <dismukes@adacore.com>

7177 * sem_ch12.adb (Analyze_Associations): minor reformatting.
7178 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed

7292 Source_File_Record as appropriate. Move Source_File_Index_Table
7293 from spec to body, because it is not used outside the body.
7294 Move Set_Source_File_Index_Table into the private part, because
7295 it is used only in the body and in children. Use trickery to
7296 modify the dope in the generic instantiation case. It's ugly,
7297 but not as ugly as the previous method. Fix documentation.
7298 Remove obsolete code.

7315 on the target type.
7316 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
7317 Remove variants that include a Supress parameter. These routines

7370 scn.ads, gnatls.adb: Eliminate the vestigial Internal_Source_File and
7371 the Internal_Source buffer. This removes the incorrect call to "="
7372 the customer noticed.
7373 Wrap remaining calls to "=" in Null_Source_Buffer_Ptr. We
7374 eventually need to eliminate them altogether. Or else get rid
7375 of zero-origin addressing.

7910 and primitive P of this type inherits non-trivial classwide
7911 preconditions from both a parent operation and from an interface
7912 operation, then the inherited operation is abstract if the parent
7913 operation is not null.

7954 * a-numeri.ads: Change the encoding of Greek letter Pi from
7955 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
7956 to indicate the encoding. We considered using a byte order mark
7957 (BOM), but that causes various trouble (misc software eats the
7958 BOM, if you have a patch with a BOM, then it's not at the start
7959 of the patch, so it's not a BOM, the BOM affects with-ing files,

8157 Use direct 4-character slice comparisons.
8158 (Has_Prefix): Add
8159 pragma Inline. (Has_Suffix): Delete.
8160 (Is_Internal_File_Name):
8161 Test Is_Predefined_File_Name first.
8162 (Is_Predefined_File_Name):
8163 Use direct slice comparisons as much as possible and limit all
8164 comparisons to at most 8 characters.
8166 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8168 * checks.adb (Insert_Valid_Check): Code cleanup.
8169 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
8170 (Expand_Actuals): Generate proper copy-back for a validation
8171 variable when it acts as the argument of a type conversion.
8172 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
8173 predicate to operate on type qualifications.
8175 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8177 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
8178 Minor reformatting.
8180 2017-04-25 Bob Duff <duff@adacore.com>
8182 * sem_prag.adb (No_Return): Give an error if the pragma applies
8183 to a body. Specialize the error for the specless body case,
8184 as is done for (e.g.) pragma Convention.
8185 * debug.adb: Add switch -gnatd.J to disable the above legality
8186 checks. This is mainly for use in our test suite, to avoid
8187 rewriting a lot of illegal (but working) code. It might also
8188 be useful to customers. Under this switch, if a pragma No_Return
8189 applies to a body, and the procedure raises an exception (as it
8190 should), the pragma has no effect. If the procedure does return,
8191 execution is erroneous.
8193 2017-04-25 Bob Duff <duff@adacore.com>
8195 * exp_ch6.adb (Expand_Actuals): This is the
8196 root of the problem. It took N as an 'in out' parameter, and in
8197 some cases, rewrote N, but then set N to Original_Node(N). So
8198 the node returned in N had no Parent. The caller continued
8199 processing of this orphaned node. In some cases that caused a
8200 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
8201 and trips over the Empty Parent). The solution is to make N an
8202 'in' parameter. Instead of rewriting it, return the list of
8203 post-call actions, so the caller can do the rewriting later,
8204 after N has been fully processed.
8205 (Expand_Call_Helper): Move most of Expand_Call here. It has
8206 too many premature 'return' statements, and we want to do the
8207 rewriting on return.
8208 (Insert_Post_Call_Actions): New procedure to insert the post-call
8209 actions in the appropriate place. In the problematic case,
8210 that involves rewriting N as an Expression_With_Actions.
8211 (Expand_Call): Call the new procedures Expand_Call_Helper and
8212 Insert_Post_Call_Actions.
8214 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8216 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
8217 properly type derived from generic formal types, to handle
8218 properly modified version of ACATS 4.1B B611017.
8220 2017-04-25 Javier Miranda <miranda@adacore.com>
8222 * exp_unst.adb (Subp_Index): Adding missing
8223 support for renamings and functions that return a constrained
8224 array type (i.e. functions for which the frontend built a
8225 procedure with an extra out parameter).
8227 2017-04-25 Pascal Obry <obry@adacore.com>
8229 * s-string.adb: Minor code clean-up.
8231 2017-04-25 Bob Duff <duff@adacore.com>
8233 * s-os_lib.ads, s-os_lib.adb (Non_Blocking_Wait_Process): New
8234 procedure.
8235 * adaint.h, adaint.c (__gnat_portable_no_block_wait): C support
8236 function for Non_Blocking_Wait_Process.
8238 2017-04-25 Bob Duff <duff@adacore.com>
8240 * prep.adb (Preprocess): Remove incorrect
8241 Assert. Current character can be ASCII.CR.
8243 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8245 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
8246 convention Stdcall, which has a number of exceptions. Convention
8247 is legal on a component declaration whose type is an anonymous
8248 access to subprogram.
8250 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8252 * sem_ch4.adb: sem_ch4.adb Various reformattings.
8253 (Try_One_Prefix_Interpretation): Use the base type when dealing
8254 with a subtype created for purposes of constraining a private
8255 type with discriminants.
8257 2017-04-25 Javier Miranda <miranda@adacore.com>
8259 * einfo.ads, einfo.adb (Has_Private_Extension): new attribute.
8260 * warnsw.ads, warnsw.adb (All_Warnings): Set warning on late
8261 dispatching primitives (Restore_Warnings): Restore warning on
8262 late dispatching primitives (Save_Warnings): Save warning on late
8263 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
8264 to enable/disable this warning.
8265 (WA_Warnings): Set warning on late dispatching primitives.
8266 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
8267 that its parent type has a private extension.
8268 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
8269 New subprogram.
8270 * usage.adb: Document -gnatw.j and -gnatw.J.
8272 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8274 * exp_ch7.adb, checks.adb, sem_prag.adb, eval_fat.adb: Minor
8275 reformatting.
8277 2017-04-25 Bob Duff <duff@adacore.com>
8279 * binde.adb (Validate): Do not pass dynamic strings
8280 to pragma Assert, because older compilers do not support that.
8282 2017-04-25 Bob Duff <duff@adacore.com>
8284 * s-fileio.adb (Close): When a temp file is
8285 closed, delete it and clean up its Temp_File_Record immediately,
8286 rather than waiting until later.
8287 (Temp_File_Record): Add File
8288 component, so Close can know which Temp_File_Record corresponds
8289 to the file being closed.
8290 (Delete): Don't delete temp files,
8291 because they are deleted by Close.
8292 (Open): Set the File component
8293 of Temp_File_Record. This requires moving the creation of the
8294 Temp_File_Record to the end, after the AFCB has been created.
8296 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8298 * checks.adb (Insert_Valid_Check): Do not generate
8299 a validity check when inside a generic.
8301 2017-04-25 Yannick Moy <moy@adacore.com>
8303 * sem_res.adb (Resolve_Type_Conversion): Fix bad logic.
8305 2017-04-25 Arnaud Charlet <charlet@adacore.com>
8307 * snames.ads-tmpl (Snames): More names for detecting predefined
8308 potentially blocking subprograms.
8310 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8312 * sem_prag.adb (Analyze_Pre_Post_Condition): The rules
8313 concerning inheritance of class-wide preconditions do not apply
8314 to postconditions.
8316 2017-04-25 Bob Duff <duff@adacore.com>
8318 * s-ficobl.ads: Minor comment fix.
8320 2017-04-25 Yannick Moy <moy@adacore.com>
8322 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
8323 conversions from float to integer in GNATprove mode.
8324 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
8325 to call Apply_Type_Conversion_Checks, so that range checks
8326 are properly positioned when needed on conversions, including
8327 when converting from float to integer. (Determine_Range): In
8328 GNATprove mode, take into account the possibility of conversion
8329 from float to integer.
8330 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
8331 check on conversions from fixed-point to integer, not anymore
8332 on conversions from floating-point to integer, when in GNATprove
8333 mode.
8335 2017-04-25 Yannick Moy <moy@adacore.com>
8337 * checks.adb (Determine_Range_R): Special case type conversions
8338 from integer to float in order to get bounds in that case too.
8339 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
8340 mode, for computations involved in interval checking.
8342 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8344 * checks.adb (Insert_Valid_Check): Partially reimplement validity
8345 checks.
8346 * einfo.adb Node36 is now used as Validated_Object.
8347 (Validated_Object): New routine.
8348 (Set_Validated_Object): New routine.
8349 (Write_Field36_Name): Add an entry for Validated_Object.
8350 * einfo.ads Add new attribute Validated_Object along with
8351 usage in entities.
8352 (Validated_Object): New routine along with pragma Inline.
8353 (Set_Validated_Object): New routine along with pragma Inline.
8354 * exp_attr.adb (Make_Range_Test): Add processing for validation
8355 variables to avoid extra reads and copies of the prefix.
8356 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
8357 variables in order to reflect any changes done in the variable
8358 back into the original object.
8359 * sem_util.adb (Is_Validation_Variable_Reference): New routine.
8360 * sem_util.ads (Is_Validation_Variable_Reference): New routine.
8362 2017-04-25 Steve Baird <baird@adacore.com>
8364 * exp_ch7.adb (Build_Array_Deep_Procs,
8365 Build_Record_Deep_Procs, Make_Finalize_Address_Body): Don't
8366 generate Finalize_Address routines for CodePeer.
8368 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8370 * sem_prag.adb (Inherits_Class_Wide_Pre): subsidiary of
8371 Analyze_Pre_Post_Condition, to implement the legality checks
8372 mandated by AI12-0131: Pre'Class shall not be specified for an
8373 overriding primitive subprogram of a tagged type T unless the
8374 Pre'Class aspect is specified for the corresponding primitive
8375 subprogram of some ancestor of T.
8377 2017-04-25 Bob Duff <duff@adacore.com>
8379 * sem_ch8.adb (Use_One_Type): If a use_type_clause
8380 is redundant, set its Used_Operations to empty. This is only
8381 necessary for use clauses that appear in the parent of a generic
8382 child unit, because those use clauses get reanalyzed when we
8383 instantiate the generic, and we don't want the Used_Operations
8384 carried over from the original context (where it was probably
8385 not redundant).
8387 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8389 * exp_ch6.adb: Minor reformatting.
8391 2017-04-25 Bob Duff <duff@adacore.com>
8393 * sem_prag.adb (Process_Restrictions_Or_Restriction_Warnings):
8394 Use Source_Index (Current_Sem_Unit) to find the correct casing.
8395 * exp_prag.adb (Expand_Pragma_Check): Use Source_Index
8396 (Current_Sem_Unit) to find the correct casing.
8397 * par.adb (Par): Null out Current_Source_File, to ensure that
8398 the above bugs won't rear their ugly heads again.
8400 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8402 * sem_ch8.adb (Find_Type): For an attribute reference
8403 'Class, if prefix type is synchronized and previous errors
8404 have suppressed the creation of the corresponding record type,
8405 create a spurious class-wide for the synchonized type itself,
8406 to catch other misuses of the attribute
8408 2017-04-25 Steve Baird <baird@adacore.com>
8410 * exp_ch6.adb (Expand_Simple_Function_Return): if CodePeer_Mode
8411 is True, then don't generate the accessibility check for the
8412 tag of a tagged result.
8413 * exp_intr.adb (Expand_Dispatching_Constructor_Call):
8414 if CodePeer_Mode is True, then don't generate the
8415 tag checks for the result of call to an instance of
8416 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
8417 descendant of" check and the accessibility check).
8419 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8421 * sem_ch13.adb: Code cleanups.
8422 * a-strbou.ads: minor whitespace fix in Trim for bounded strings.
8423 * sem_ch8.ads: Minor comment fix.
8425 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8427 * exp_ch4.adb (Library_Level_Target): New function.
8428 (Expand_Concatenate): When optimization is enabled, also expand
8429 the operation out-of-line if the concatenation is present within
8430 the expression of the declaration of a library-level object and
8431 not only if it is the expression of the declaration.
8433 2017-04-25 Bob Duff <duff@adacore.com>
8435 * freeze.adb (Freeze_Object_Declaration): Do
8436 not Remove_Side_Effects if there is a pragma Linker_Section,
8437 because in that case we want static initialization in the
8438 appropriate section.
8440 2017-04-25 Gary Dismukes <dismukes@adacore.com>
8442 * exp_dbug.adb: Minor rewording and reformatting.
8444 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8446 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
8447 handle the proposed changes to rules concerning potentially
8448 unevaluated expressions, to include selected components that
8449 do not depend on discriminants, and indexed components with
8450 static indices.
8451 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
8452 predicate in quantified expression, and fix bugs in the handling
8453 of case expressions and membership test.
8454 (Analyze_Attribute_Old_Result): use new predicate.
8455 (Analyze_Attribute, case Loop_Entry): ditto.
8457 2017-04-25 Bob Duff <duff@adacore.com>
8459 * s-secsta.adb (SS_Info): Add a comment
8460 explaining why we don't need to walk all the chunks in order to
8461 compute the total size.
8463 2017-04-25 Bob Duff <duff@adacore.com>
8465 * namet.ads, namet.adb (Global_Name_Buffer): Increase the length
8466 of the global name buffer to 4*Max_Line_Length.
8468 2017-04-25 Javier Miranda <miranda@adacore.com>
8470 * exp_ch8.adb (Expand_N_Object_Renaming_Declaration): When creating a
8471 renaming entity for debug information, mark the entity as needing debug
8472 info if it comes from sources.
8474 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8476 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Remove the
8477 restriction converning the use of 'Address where the prefix is
8478 of a controlled type.
8480 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
8482 * exp_dbug.adb: In Debug_Renaming_Declaration,
8483 skip slices that are made redundant by an indexed component
8484 access.
8485 * atree.h: New definition for Original_Node.
8487 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8489 * sem_prag.adb, sem_prag.ads: Minor reformatting.
8491 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8493 * sem_ch3.adb (Check_Entry_Contract): Call
8494 Preanalyze_Spec_Expression so that resolution takes place as well.
8495 * sem_util.adb (Check_Internal_Protected_Use): Reject properly
8496 internal calls that appear in preconditions of protected
8497 operations, in default values for same, and in contract guards
8498 for contract cases in SPARK.
8500 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8502 * a-numaux.ads: Fix description of a-numaux-darwin
8503 and a-numaux-x86.
8504 (Double): Define to Long_Float.
8505 * a-numaux-vxworks.ads (Double): Likewise.
8506 * a-numaux-darwin.ads
8507 (Double): Likewise.
8508 * a-numaux-libc-x86.ads (Double): Define to Long_Long_Float.
8509 * a-numaux-x86.ads: Fix package description.
8510 * a-numaux-x86.adb (Is_Nan): Minor tweak.
8511 (Reduce): Adjust and complete description. Call Is_Nan instead of
8512 testing manually. Use an integer temporary to hold rounded value.
8513 * a-numaux-darwin.adb (Reduce): Likewise.
8514 (Is_Nan): New function.
8516 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8518 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
8519 on analysis of prefix whose type is a current instance of a
8520 synchronized type, but where the prefix itself is an entity that
8521 is an object.
8523 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8525 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
8526 the identity of callable entities therein, because they have been
8527 properly resolved, and prefixed calls may have been rewritten
8528 as normal calls.
8530 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
8532 * exp_ch3.adb (Build_Init_Statements): Convert
8533 the expression of the pragma/aspect Secondary_Stack_Size to
8534 internal type System.Parameters.Size_Type before assigning
8535 it to the Secondary_Stack_Size component of the task type's
8536 corresponding record.
8538 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8540 * sem_eval.adb (Compile_Time_Compare): Reinstate the expr+literal
8541 (etc) optimizations when the type is modular and the offsets
8542 are equal.
8544 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8546 * s-osinte-freebsd.ads: Minor comment tweaks
8548 2017-04-25 Javier Miranda <miranda@adacore.com>
8550 * urealp.adb (UR_Write): Reverse previous patch
8551 adding documentation on why we generate multiplications instead
8552 of divisions (needed to avoid expressions whose computation with
8553 large numbers may cause division by 0).
8555 2017-04-25 Bob Duff <duff@adacore.com>
8557 * erroutc.adb (Set_Specific_Warning_Off,
8558 Set_Warnings_Mode_Off): Use the correct source file for
8559 Stop. Was using Current_Source_File, which is only valid during
8560 parsing. Current_Source_File will have a leftover value from
8561 whatever file happened to be parsed last, because of a with_clause
8562 or something.
8564 2017-04-25 Bob Duff <duff@adacore.com>
8566 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
8567 to In_Predefined_Unit, but including GNAT units.
8568 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
8569 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
8570 because Should_Ignore_Pragma was not working reliably outside
8571 the parser, because Current_Source_File is not valid.
8572 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
8573 * par-prag.adb: Call Should_Ignore_Pragma_Par.
8575 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>
8577 * gnat1drv.adb (Gnat1Drv): Disable Generate_Processed_File in
8578 codepeer mode.
8580 2017-04-25 Javier Miranda <miranda@adacore.com>
8582 * urealp.adb (UR_Write): Fix output of constants with a base other
8583 that 10.
8585 2017-04-25 Justin Squirek <squirek@adacore.com>
8587 * sem_ch13.adb (Get_Interfacing_Aspects): Moved to sem_util.adb.
8588 * sem_prag.adb (Analyze_Pragma, Process_Import_Or_Interface):
8589 Add extra parameter for Process_Interface_Name.
8590 (Process_Interface_Name): Add parameter for pragma to analyze
8591 corresponding aspect.
8592 * sem_util.ads, sem_util.adb (Get_Interfacing_Aspects): Added
8593 from sem_ch13.adb
8595 2017-04-25 Gary Dismukes <dismukes@adacore.com>
8597 * exp_ch7.adb, einfo.ads, sem_prag.adb: Minor reformatting and typo
8598 correction.
8600 2017-04-25 Yannick Moy <moy@adacore.com>
8602 * sem_res.adb (Resolve_Comparison_Op): Do not
8603 attempt evaluation of relational operations inside assertions.
8605 2017-04-25 Justin Squirek <squirek@adacore.com>
8607 * exp_util.adb (Add_Interface_Invariants):
8608 Restored, code moved back from Build_Invariant_Procedure_Body.
8609 (Add_Parent_Invariants): Restored, code moved back from
8610 Build_Invariant_Procedure_Body.
8611 (Build_Invariant_Procedure_Body):
8612 Remove refactored calls and integrated code from
8613 Add_Parent_Invariants and Add_Interface_Invariants.
8615 2017-04-25 Johannes Kanig <kanig@adacore.com>
8617 * errout.adb (Output_Messages): Adjust computation of total
8618 errors
8619 * erroutc.adb (Error_Msg): In statistics counts, deal
8620 correctly with informational messages that are not warnings.
8621 * errutil.adb (Finalize): adjust computation of total errors.
8623 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>
8625 * terminals.c (__gnat_terminate_pid): New.
8626 * g-exptty.ads (Terminate_Process): New. Update comments.
8628 2017-04-25 Arnaud Charlet <charlet@adacore.com>
8630 * a-cfinve.ads, a-cofove.ads (Empty_Vector): add Global contract.
8632 2017-04-25 Justin Squirek <squirek@adacore.com>
8634 * sem_ch3.adb (Analyze_Declarations): Minor
8635 correction to comments, move out large conditional and scope
8636 traversal into a predicate.
8637 (Uses_Unseen_Lib_Unit_Priv): Predicate function made from extracted
8638 logic.
8640 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8642 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
8643 of prefix whose type is a current instance of a synchronized
8644 type. If the prefix is an object this is an external call (or
8645 requeue) that can only access public operations of the object. The
8646 previous predicate was too restrictive, and did not allow public
8647 protected operations, only task entries.
8649 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8651 * sem_ch5.adb, fname.adb: Minor reformatting.
8653 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8655 * einfo.adb (Is_Anonymous_Access_Type): New routine.
8656 * einfo.ads Update the placement of
8657 E_Anonymous_Access_Subprogram_Type along with all subtypes that
8658 mention the ekind.
8659 (Is_Anonymous_Access_Type): New routine.
8660 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
8661 master for an access type subject to pragma No_Heap_Finalization.
8662 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
8663 allocated or deallocated does not finalization actions if the
8664 associated access type is subject to pragma No_Heap_Finalization.
8665 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
8666 * par-prag.adb Pragma No_Heap_Finalization does not need special
8667 processing from the parser.
8668 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
8669 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
8670 * sem_prag.adb Add an entry in table Sig_Flags for pragma
8671 No_Heap_Finalization.
8672 (Analyze_Pragma): Add processing for

8681 * freeze.adb (Freeze_Record_Type): Use the
8682 underlying type of the component type to determine whether it's
8683 elementary. For representation clause purposes, a private type
8684 should behave the same as its full type.
8685 * fname.ads, fname.adb (Is_Predefined_File_Name):
8686 Make sure things like "system.ali" are recognized as predefined.
8688 2017-04-25 Javier Miranda <miranda@adacore.com>

8700 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
8701 Is_Internal_Unit_Name): New functions for operating on unit
8702 names, as opposed to file names. There's some duplicated code
8703 with fname.adb, which is unfortunate, but it seems like we don't
8704 want to add dependencies here.
8705 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
8706 to Is_Predefined_Unit_Name; the former was wrong, because Uname
8707 is not a file name at all.
8708 * fname.ads, fname.adb: Document the fact that
8709 Is_Predefined_File_Name and Is_Internal_File_Name can be called
8710 for ALI files, and fix the code so it works properly for ALI
8711 files. E.g. these should return True for "system.ali".
8713 2017-04-25 Justin Squirek <squirek@adacore.com>
8715 * exp_util.adb (Add_Invariant): Removed,
8716 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
8717 and Add_Own_Invariant. (Add_Invariant_Check): Used
8718 for adding runtime checks from any kind of invariant.
8719 (Add_Inherited_Invariant): Generates invariant checks for
8720 class-wide invariants (Add_Interface_Invariants): Removed, code
8721 moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):

8725 and integrated code from Add_Parent_Invariants and
8726 Add_Interface_Invariants.

8728 relavant code was inlined into both Add_Own_Invariant and
8729 Add_Inherited_Invariant.

8751 * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
8752 and Build_Invariant_Procedure_Declaration from exp_ch7
8753 and break-out Is_Untagged_Private_Derivation from
8754 Build_Invariant_Procedure_Body.
8755 (Replace_Type_References):
8756 Append an extra parameter to allow for dispatching replacements
8757 and add the corrasponding logic.
8758 (Type_Invariant): Remove
8759 Replace_Typ_Refs and replace its references with calls to
8760 Replace_Type_References.
8761 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.

8768 when compiling predefined files.
8769 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
8770 "gnat.adc" should not be considered a predefined file name.
8771 That required (or at least encouraged) a lot of cleanup of global
8772 variable usage. We shouldn't be communicating information via
8773 the global name buffer.
8774 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
8775 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes
8776 required by the above-mentioned cleanup.

8834 * sem_ch5.adb (Analyze_Assignment): Reset Full_Analysis flag on
8835 the first pass over an assignment statement with target names,
8836 to prevent the generation of subtypes (such as discriminated
8837 record components)that may carry the target name outside of the

8839 the assignment is reanalyzed in full.
8840 (Analyze_Target_Name): Handle properly class-wide types.

8851 refer to the proper entities. Update the replacement of
8852 references.
8853 (Build_DIC_Procedure_Body): Add formal parameter
8854 For_Freeze. Add local variable Build_Body. Inherited DIC pragmas
8855 are now only processed when freezing occurs. Build a body only

8875 DIC pragma is placed at the top of a declarative region.
8877 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>

8885 the error message when the attribute reference is an actual in
8886 a call to a subprogram inherited from a generic formal type with
8887 unknown discriminants, which makes the subprogram and its formal
8888 parameters intrinsic (see RM 6.3.1 (8) and (13)).
8890 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8892 * sem_aggr.adb, inline.adb, einfo.adb, einfo.ads, scng.adb,

8897 * sem_attr.adb (Type_Key): Add code in the
8898 recursive Compute_Type_Key to protect against fetching the source
8899 code for Standard, in case a component of the type is declared
8900 in Standard. There was already code to do this for the original
8901 type, but not for its components.

8922 * sem_prag.adb (Process_Inline): Set Body_Needed_For_Inlining if
8923 context is a package declaration.

9118 * sem_util.adb (New_Copy_Tree): By default
9119 copying of defining identifiers is prohibited because
9120 this would introduce an entirely new entity into the
9121 tree. This patch introduces an exception to this general
9122 rule: the declaration of constants and variables located in
9123 Expression_With_Action nodes.
9124 (Copy_Itype_With_Replacement): Renamed as Copy_Entity_With_Replacement.
9125 (In_Map): New subprogram.

9643 * exp_spark.adb (Expand_SPARK_Attribute_Reference): For
9644 attributes which return Universal_Integer, introduce a conversion
9645 to the expected type with the appropriate check flags set.
9646 * sem_res.adb (Resolve_Range): The higher bound can be in Typ's
9647 base type if the range is null. It may still be invalid if it

9664 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
9665 an object declaration for an array type with a modular index type
9666 with the size of Long_Long_Integer. Special processing is needed
9667 in this case to compute reliably the size of the object, and
9668 eventually to raise Storage_Error, when wrap-around arithmetic
9669 might compute a meangingless size for the object.
9671 2017-01-23 Justin Squirek <squirek@adacore.com>

9679 it is deciding whether to turn the call into an indexed
9680 component, avoid doing so if the call is to an instance of
9681 Unchecked_Conversion. Otherwise, the compiler turns it into an
9682 indexed component, and resolution of that turns it back into a
9683 function call, and so on, resulting in infinite recursion.
9684 * sem_util.adb (Needs_One_Actual): If the first formal has a
9685 default, then return False.

9787 returns a limited view of a type and at the point of the call the
9788 function is not declared in the extended main unit then replace
9789 it with the non-limited view, which must be available. If the
9790 called function is in the extended main unit then no action is
9791 needed since the back-end handles this case.

9803 2017-01-20 Ed Schonberg <schonberg@adacore.com>
9805 * sem_ch3.adb (Complete_Private_Subtype): If the scope of the
9806 base type differs from that of the completion and the private
9807 subtype is an itype (created for a constraint on an access

10138 public, for use elsewhere.
10139 * sem_ch6.adb (Analyze_Procedure_Call): In SPARK_Mode and within
10140 an Inlined_body, recognize a call that uses object notation
10141 and has not been rewritten as a regular call because regular
10142 expansion has not taken place.
10144 2017-01-19 Bob Duff <duff@adacore.com>
10146 * checks.adb (Apply_Type_Conversion_Checks): Disable small optimization
10147 in case of generic formal discrete types, because it causes crashes in
10148 the compiler when built with assertions on.

10159 wrong since we just issued a warning message.
10160 * binderr.ads (Errors_Detected, Warnings_Detected): Declare
10161 these variables to be of subtype Nat instead of Int, because
10162 they should never be negative.

10193 2017-01-19 Ed Schonberg <schonberg@adacore.com>
10195 * sem_ch4.adb (Diagnose_Call): Improve error message when a
10196 selected component has a prefix that might be interpreted
10197 as a parameterless function call, but none of the candidate
10198 interpretations is parameterless, and there is a hidden homonym
10199 of the prefix that is a package.
10200 * sem_ch8.adb (Find_Selected_Component): If the prefix might be
10201 interpreted as a parameterless function call and its analysis
10202 fails, do not call Analyze_Selected_Component.
10204 2017-01-19 Steve Baird <baird@adacore.com>
10206 * sem_util.ads: Add new Use_Full_View Boolean parameter to
10207 Get_Index_Bounds.

10216 * lib-xref-spark_specific.adb (Traverse_Stub): routine refactored
10217 from repeated code of Traverse_Compilation_Unit.
10218 (Traverse_Declaration_Or_Statement): fixed detection of
10219 generic subprograms and packages; also, iteration over case
10220 statement alternatives rewritten to avoid testing if the first
10221 alternative is present (since it must be present due to Ada
10222 syntax restrictions).

10236 * sem_dim.adb (Analyze_Dimension): Analyze object declaration and
10237 identifier nodes that do not come from source, to handle properly
10238 dimensionality check within an inlined body which inclddes both
10239 original operands and rewritten operands. This removes spurious
10240 dimensionality errors in the presence of front-end inlining,

10359 2017-01-13 Bob Duff <duff@adacore.com>
10361 * binde.adb (Elab_New): New elaboration order algorithm
10362 that is expected to cause fewer ABE issues. This is a work in
10363 progress. The new algorithm is currently disabled, and can be
10364 enable by the -dp switch, or by modifying the Do_Old and Do_New
10365 etc. flags and rebuilding. Experimental code is included to
10366 compare the results of the old and new algorithms.
10367 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
10368 can have multiple of these tables, so the old and new algorithms
10369 can coexist.
10370 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
10371 parameter of type array. This avoids the global variable, and
10372 allows bounds checking (which is normally defeated by the tables
10373 packages). It also ensures that the Elab_Order is read-only
10374 to Bindgen.
10375 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
10376 subprograms that need it, as above.
10377 * debug.adb: Document new -dp switch. Modify doc of old -do
10378 switch.
10379 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
10380 and Bindgen. Move writing of closure (-R and -Ra switches)
10381 to Binde; that's more convenient.
10383 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10385 * sem_ch6.adb (Analyze_Expression_Function): If the expression
10386 function is a completion, all entities referenced in the
10387 expression are frozen. As a consequence, a reference to an
10388 uncompleted private type from an enclosing scope is illegal.
10390 2017-01-13 Javier Miranda <miranda@adacore.com>
10392 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
10393 (Analyze_Subprogram_Body_Helper): At the occurrence of an
10394 expression function declaration that is a completion, its
10395 expression causes freezing (AI12-0103).

10420 an Iterated_component_ association.
10421 (Resolve_Iterated_Component_Association): An others choice
10422 is legal.
10423 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An
10424 Iterated_Component_Association is not static.
10426 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
10428 * exp_ch3.adb (Freeze_Type): Mark the Ghost mode as set in case

10450 * sem_aggr.adb (Resolve_Array_Aggregate): Remove
10451 Iterated_Component_Present.
10452 * exp_aggr.adb: Use Choice_List throughout, to handle
10453 Iterated_Component_Associations.
10454 (Gen_Loop): Generate proper loop for an
10455 Iterated_Component_Association: loop variable has the identifier
10456 of the original association. Generate a loop even for a single
10457 component choice, in order to make loop parameter visible in
10458 expression.
10459 (Flatten): An Iterated_Component_Association is not static.
10461 2017-01-13 Yannick Moy <moy@adacore.com>
10463 * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
10464 float exponentiation for statically known small negative values
10465 is the reciprocal of the exponentiation for the opposite value
10466 of the exponent.
10467 * s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):
10468 Ensure that the value of float exponentiation for negative values
10469 is the reciprocal of the exponentiation for the opposite value
10470 of the exponent.
10471 * inline.adb (Expand_Inlined_Call): Fix the count

10480 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10482 * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
10483 mode a choice that is a subtype with a static predicate is
10484 replaced by the values it covers. This transformation must not
10485 be performed in ASIS mode, to preserve the source for analysis.

10498 Iterated_Component_Association is a named association in an
10499 array aggregate.
10500 * sem_aggr.adb (Resolve_Iterated_Component_Association): New
10501 procedure, subsidiary of Resolve_Array_Aggregate, to analyze
10502 and resolve the discrete choices and the expression of the
10503 new construct.
10504 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
10505 Loop_Actions and Box_Present are attributes of
10506 N_Iterated_Component_Association nodes. Box_Present is always
10507 False in this case.
10508 * sprint.adb (Sprint_Node): An Iterated_Component_Association
10509 has a Discrete_Choices list, as specified in the RM. A
10510 Component_Association for aggregate uses instead a Choices list.
10511 We have to live with this small inconsistency because the new
10512 construct also has a defining identifier, and there is no way
10513 to merge the two node structures.

10522 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10524 * sem_ch3.adb (Resolve_Aspects): New procedure, subsidiary of
10525 Analyze_Declarations, to analyze and resolve the expressions of
10526 aspect specifications in the current declarative list, so that
10527 the expressions have proper entity and type info. This is needed
10528 for ASIS when there is no subsequent expansion to generate this
10529 semantic information.
10530 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
10531 original expression, to suppress cascaded errors when expression
10532 has been constant-folded.
10533 (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
10534 ASIS mode, because there is no subsequent expansion to decorate
10535 the tree.
10537 2017-01-13 Yannick Moy <moy@adacore.com>
10539 * inline.adb, inline.ads (Call_Can_Be_Inlined_In_GNATprove_Mode):
10540 New function to detect when a call may be inlined or not in
10541 GNATprove mode.
10542 (Expand_Inlined_Call): Ensure that a temporary
10543 is always created in the cases where a type conversion may be
10544 needed on an input parameter in GNATprove mode, so that GNATprove
10545 sees the check to perform.
10546 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
10547 when not applicable due to actual requiring type conversion
10548 with possible check but no temporary value can be copied for
10549 GNATprove to see the check.

11856 for accessing and setting were added as well.
11857 * par-prag.adb (Prag): Register Pramga_Max_Entry_Queue.
11858 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): Emit
11859 declaration for pramga arguments and store them in the protected
11860 type node.
11861 (Make_Initialize_Protection): Pass a reference to
11862 the Entry_Max_Queue_Lengths_Array in the protected type node to
11863 the runtime.
11864 * rtsfind.adb: Minor grammar fix.
11865 * rtsfind.ads: Register new types taken from the
11866 runtime libraries RE_Protected_Entry_Queue_Max and
11867 RE_Protected_Entry_Queue_Max_Array
11868 * s-tposen.adb, s-tpoben.adb
11869 (Initialize_Protection_Entry/Initialize_Protection_Entries):
11870 Add extra parameter and add assignment to local object.
11871 * s-tposen.ads, s-tpoben.ads: Add new types to
11872 store entry queue maximums and a field to the entry object record.
11873 * sem_ch13.adb (Analyze_Aspect_Specifications): Add case statement
11874 for Aspect_Max_Queue_Length.
11875 (Check_Aspect_At_Freeze_Point):
11876 Add aspect to list of aspects that don't require delayed analysis.
11877 * sem_prag.adb (Analyze_Pragma): Add case statement for
11878 Pragma_Max_Queue_Length, check semantics, and register arugments
11879 in the respective entry nodes.
11880 * sem_util.adb, sem_util.ads Add functions Get_Max_Queue_Length
11881 and Has_Max_Queue_Length
11882 * snames.ads-tmpl: Add constant for the new aspect-name
11883 Name_Max_Queue_Length and corrasponding pragma.
11885 2017-01-06 Hristian Kirtchev <kirtchev@adacore.com>
11887 * exp_util.adb (Is_Controlled_Function_Call):
11888 Reimplemented. Consider any node which has an entity as the
11889 function call may appear in various ways.
11891 2017-01-06 Hristian Kirtchev <kirtchev@adacore.com>
11893 * exp_attr.adb (Rewrite_Stream_Proc_Call): Use
11894 an unchecked type conversion when performing a view conversion
11895 to/from a private type. In all other cases use a regular type
11896 conversion to ensure that any relevant checks are properly
11897 installed.
11899 2017-01-06 Hristian Kirtchev <kirtchev@adacore.com>
11901 * sem_prag.adb, sem_ch8.adb: Minor reformatting.
11903 2017-01-06 Ed Schonberg <schonberg@adacore.com>
11905 * sem_case.adb (Explain_Non_Static_Bound): Suppress cascaded
11906 error on case expression that is an entity, when coverage is
11907 incomplete and entity has a static value obtained by local
11908 propagation.
11909 (Handle_Static_Predicate): New procedure, subsidiary of
11910 Check_Choices, to handle case alternatives that are either
11911 subtype names or subtype indications involving subtypes that
11912 have static predicates.
11914 2017-01-06 Thomas Quinot <quinot@adacore.com>
11916 * s-oscons-tmplt.c, g-socket.adb, g-socket.ads, g-sothco.ads:

11921 * sem_elab.adb (Activate_Elaborate_All_Desirable): Don't add
11922 Elaborate_All(P) to P itself. That could happen in obscure cases,
11923 and always introduced a cycle (P body must be elaborated before
11924 P body).
11925 * lib-writ.ads: Comment clarification.
11926 * ali-util.ads: Minor comment fix.
11927 * ali.adb: Minor reformatting.
