1881 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Simplify code to
1882 create the procedure body for an function returning an array type,
1883 when generating C code. Reuse the subprogram body rather than

1975 (Analyze_Pragma, case Pure): Do not check placement if pragma
1976 appears within an instantiation, which can be nested at any level.
1977 * sem_ch12.adb (Analyze_Instance_And_Renamings): Do not copy Freeze

2075 conditioned by the value of this flag, whose default is True.
2076 * sem_attr.adb (Resolve_Attribute, case 'Access): The attribute
2077 reference freezes the prefix, but it the prefix is a subprogram
2078 it does not freeze its profile.
2080 2016-04-21 Javier Miranda <miranda@adacore.com>
2082 * exp_util.adb (Build_Procedure_Form): No action needed for
2083 subprogram renamings since the backend can generate the call
2084 using the renamed subprogram. This leaves the tree more clean

2100 Handle Extended_Return_Statements by replacing it with a block
2101 with assignments and a simple return statement.

2108 * sem_ch6.adb (Build_Subprogram_Declaration): Propagate the
2109 attribute Rewritten_For_C to the body since since the expander

2193 * sem_ch13.adb (Build_Predicate_Function_Declaration): New
2194 function, to construct the declaration of a predicate function
2195 at the end of the current declarative part rather than at the
2196 (possibly later) freeze point of the type. This also allows uses
2197 of a type with predicates in instantiations elsewhere.

2199 errors in aspect expressions, at the end of the declarative part
2200 that includes the type declaration.

2236 * sem_ch6.adb (Enter_Overloaded_Entity): Do not warn about
2237 hiding unless we're actually hiding something. The previous
2238 code would (for example) warn about a "<" on a record type
2239 because it incorrectly thought it was hiding the "<" on Boolean
2240 in Standard. We need to check that the homonym S is in fact a
2241 homograph of a predefined operator.

2250 function that renames an instance of Unchecked_Conversion.
2251 * freeze.adb (Freeze_Subprogram): Generate the proper procedure
2252 declaration for a function returning an array.

2586 * sem_ch13.adb (Add_Invariant): Do not replace
2587 the saved expression of an invariatn aspect when inheriting
2588 a class-wide type invariant as this clobbers the existing
2589 expression. Do not use New_Copy_List as it is unnecessary
2590 and leaves the parent pointers referencing the wrong part of
2591 the tree. Do not replace the type references for ASIS when
2592 inheriting a class-wide type invariant as this clobbers the
2593 existing replacement.
2595 2016-04-20 Ed Schonberg <schonberg@adacore.com>
2597 * sem_util.adb (Build_Explicit_Dereference): If the designated

2643 another unit and cannot be frozen at this point.
2645 2016-04-19 Ed Schonberg <schonberg@adacore.com>
2647 * exp_aggr.adb (Component_Count): Handle properly superflat
2648 arrays, i.e. empty arrays where Hi < Lo - 1, to ensure that the
2649 return value of the function is Natural, rather than leaving
2650 the handling of such arrays to the caller of this function.
2652 2016-04-19 Arnaud Charlet <charlet@adacore.com>

2728 2016-04-19 Hristian Kirtchev <kirtchev@adacore.com>
2730 * sem_disp.adb (Check_Dispatching_Context): Code cleanup. Add

2769 * sem_prag.adb (Analyze_Pragma): Pragma Ghost can now apply to
2770 a subprogram declaration that acts as a compilation unit.

2844 * exp_ch4.adb (Optimize_Length_Comparison): Return immediately
2845 in the case of AAMP (same as for use of the -gnatd.P switch) to

2849 2016-04-18 Arnaud Charlet <charlet@adacore.com>
2851 * exp_ch4.adb: Update comment.

2881 element type is done elsewhere.
2883 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2885 * sem_ch6.adb (Process_Formals): Do not set a delay freeze on
2886 a subprogram that returns a class-wide type, if the subprogram
2887 is a compilation unit, because otherwise gigi will treat the
2888 subprogram as external, leading to link errors.
2890 2016-04-18 Arnaud Charlet <charlet@adacore.com>
2892 * sem_res.adb (Resolve_Short_Circuit): Do not use
2893 expression-with-actions when generating C.

2913 or implicit).
2915 2016-04-18 Arnaud Charlet <charlet@adacore.com>
2917 * osint-c.ads, osint-c.adb (Delete_C_File, Delete_H_File): New.

2939 * sem_prag.adb (Check_In_Out_States.Check_Constituent_Usage):
2940 Update the comment on usage. Reimplemented.
2941 (Check_Input_States.Check_Constituent_Usage): Update the comment
2942 on usage. A Proof_In constituent can now refine an Input state
2943 as long as there is at least one Input constituent present.
2945 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2947 * sem_ch6.adb (Check_Inline_Pragma): Use the Sloc of the
2948 body id as the sloc of the entity in the generated subprogram
2949 declaration, to avoid spurious conformance errors when style
2950 checks are enabled.
2952 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2954 * sem_ch4.adb (Analyze_Selected_Component, Has_Dereference):
2955 Refine check on illegal calls to entities within a task body,
2956 when the entity is declared in an object of the same type. In
2957 a generic context there might be no explicit dereference but if
2958 the prefix includes an access type the construct is legal.
2960 2016-04-18 Arnaud Charlet <charlet@adacore.com>

2974 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2976 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): To suppress
2977 superfluous conformance check on an inlined body with a previous
2978 spec, use the fact that the generated declaration does not come
2979 from source. We must treat the entity as coming from source to
2980 enable some back-end inlining when pragma appears after the body.
2982 2016-04-18 Gary Dismukes <dismukes@adacore.com>
2984 * lib-xref-spark_specific.adb, par-ch2.adb, errout.ads,

3000 2016-04-18 Bob Duff <duff@adacore.com>
3002 * s-fileio.adb (Fopen_Mode): If Mode = Out_File, and the file
3003 exists, and it's a fifo, we use "w" as the open string instead of
3004 "r+". This is necessary to make a write to the fifo block until
3005 a reader is ready.

3009 * sem_attr.adb (Denote_Same_Function): Account
3010 for a special case where a primitive of a tagged type inherits
3011 a class-wide postcondition from a parent type.
3013 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
3015 * par-ch2.adb (P_Expression_Or_Reserved_Word): New routine.
3016 (P_Pragma): Signal Scan_Pragma_Argument_Association when the use
3017 of reserved words is OK.
3018 (Scan_Pragma_Argument_Association):
3019 Add new formal Reserved_Words_OK and update the comment on
3020 usage. Code cleanup. Parse an expression or a reserved word in
3021 identifier form for pragmas Restriction_Warnings and Restrictions
3022 No_Use_Of_Attribute.
3023 * restrict.adb (Check_Restriction_No_Use_Of_Attribute):
3024 Reimplemented. (Check_Restriction_No_Use_Of_Pragma): Code cleanup.
3025 (Set_Restriction_No_Specification_Of_Aspect): Properly set the warning
3026 flag for an aspect.
3027 (Set_Restriction_No_Use_Of_Attribute): Properly set the warning
3028 flag for an attribute. (Set_Restriction_No_Use_Of_Entity):
3029 Update the parameter profile.
3030 (Set_Restriction_No_Use_Of_Pragma): Properly set the warning flag for
3031 a pragma.
3032 * restrict.ads (Check_Restriction_No_Use_Of_Attribute): Update
3033 the comment on usage.
3034 (Set_Restriction_No_Use_Of_Entity): Update the parameter profile.
3035 * sem_attr.adb (Analyze_Attribute): Check restriction
3036 No_Use_Of_Attribute.
3037 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Check
3038 restriction No_Use_Of_Attribute before any rewritings have
3039 taken place.
3040 * sem_prag.adb (Analyze_Pragma): Check restriction
3041 No_Use_Of_Pragma before any rewritings have taken place.
3043 2016-04-18 Bob Duff <duff@adacore.com>
3045 * sem_ch6.adb (Is_Inline_Pragma): The pragma
3046 argument can be a selected component, which has no Chars field,
3047 so we need to deal with that case (use the Selector_Name).
3048 (Check_Inline_Pragma): We need to test Is_List_Member before
3049 calling In_Same_List, because in case of a library unit, they're
3050 not in lists, so In_Same_List fails an assertion.
3052 2016-04-18 Bob Duff <duff@adacore.com>
3054 * namet.ads, namet.adb: Add an Append that appends a
3055 Bounded_String onto a Bounded_String. Probably a little more
3056 efficient than "Append(X, +Y);". Also minor cleanup.
3057 (Append_Decoded, Append_Decoded_With_Brackets, Append_Unqualified,
3058 Append_Unqualified_Decoded): Make sure these work with non-empty
3059 buffers.
3060 * casing.ads, casing.adb (Set_Casing): Pass a Bounded_String
3061 parameter, defaulting to Global_Name_Buffer.
3062 * errout.ads, errout.adb (Adjust_Name_Case): Pass a
3063 Bounded_String parameter, no default.
3064 * exp_ch11.adb (Expand_N_Raise_Statement): Use local
3065 Bounded_String instead of Global_Name_Buffer.
3066 * exp_intr.ads, exp_intr.adb (Write_Entity_Name): Rename it
3067 to Append_Entity_Name, and pass a Bounded_String parameter,
3068 instead of using globals.
3069 (Add_Source_Info): Pass a Bounded_String parameter, instead of
3070 using globals.
3071 (Expand_Source_Info): Use local instead of globals.
3072 * stringt.ads, stringt.adb (Append): Add an Append procedure
3073 for appending a String_Id onto a Bounded_String.
3074 (String_To_Name_Buffer, Add_String_To_Name_Buffer): Rewrite in
3075 terms of Append.
3076 * sem_prag.adb (Set_Error_Msg_To_Profile_Name): Adjust for new
3077 Adjust_Name_Case parameter.
3078 * erroutc.adb, uname.adb: Don't pass D => Mixed_Case to
3079 Set_Casing; that's the default.
3080 * lib-xref-spark_specific.adb (Add_SPARK_Scope): Pretend that calls to
3081 protected subprograms are entry calls; otherwise it is not possible to
3082 distinguish them from regular subprogram calls.
3084 2016-04-18 Gary Dismukes <dismukes@adacore.com>
3086 * sem_ch13.adb (Has_Good_Profile): Improvement
3087 of error message. Now indicates subtype_mark of formal parameter
3088 rather than the formal's name, plus minor rewording.
3090 2016-04-18 Pascal Obry <obry@adacore.com>
3092 * adaint.c, adaint.h, s-os_lib.ads: Add new routine Current_Process_Id.
3094 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
3096 * stringt.adb, exp_ch6.adb, sem_ch13.adb: Minor reformatting.
3098 2016-04-18 Gary Dismukes <dismukes@adacore.com>
3100 * par-ch4.adb, sem_prag.adb: Minor reformatting.
3102 2016-04-18 Bob Duff <duff@adacore.com>
3104 * sinput.ads, sinput.adb (Build_Location_String): Take a
3105 parameter instead of using a global variable. The function
3106 version no longer destroys the Name_Buffer.
3107 * stringt.ads, stringt.adb (String_From_Name_Buffer): Take a
3108 parameter, which defaults to the Global_Name_Buffer, so some
3109 calls can avoid the global.
3110 * exp_ch11.adb, exp_intr.adb: Use new interfaces above
3111 to avoid using globals. All but one call to Build_Location_String
3112 avoids the global. Only one call to String_From_Name_Buffer
3113 avoids it.
3115 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
3117 * namet.adb, namet.ads, exp_unst.adb: Minor reformatting.
3119 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
3121 * sem_eval.adb (Choice_Matches): Check the expression
3122 against the predicate values when the choice denotes a
3123 subtype with a static predicate.
3124 (Eval_Membership_Op): Code cleanup. Remove the suspicious guard which
3125 tests for predicates.
3126 (Is_OK_Static_Subtype): A subtype with a dynamic predicate
3127 is not static. (Is_Static_Subtype): A subtype with a dynamic
3128 predicate is not static.
3129 * sem_eval.ads (Is_OK_Static_Subtype): Update the comment on usage.
3130 (Is_Static_Subtype): Update the comment on usage.
3132 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
3134 * sem_prag.adb (Analyze_Input_Item): Allow
3135 generic formals to appear as initialization items.
3137 2016-04-18 Ed Schonberg <schonberg@adacore.com>
3139 * sem_ch13.adb (Analyze_Stream_TSS_Definition,
3140 Has_Good_Profile): Additional error message to indicate that
3141 the second parameter of the subprogram must be a first subtype.
3143 2016-04-18 Ed Schonberg <schonberg@adacore.com>
3145 * sem_ch6.adb (Analyze_Subprogram_Body_Helper, Is_Inline_Pragma):
3146 Use the pragma lookahead that determines whether a subprogram
3147 is to be inlined, when some level of backend optimization is
3148 required.
3149 * sem_ch12.ads, sem_ch12.adb (Add_Pending_Instantiation): Factorize
3150 code used to create an instance body when needed for inlining.
3151 * exp_ch6.adb (Expand_Call): When a call is to be inlined, and the
3152 call appears within an instantiation that is not a compilation
3153 unit, add a pending instantiation for the enclosing instance,
3154 so the backend can inline in turn the calls contained in the
3155 inlined body.
3157 2016-04-18 Ed Schonberg <schonberg@adacore.com>
3159 * sem_prag.adb (Build_Pragma_Check_Equivalent): The mapping
3160 that relates operations of the parent type to the operations of
3161 the derived type has three distinct sources:
3162 a) explicit operations of the derived type carry an
3163 Overridden_Operation that designates the operation in the
3164 ancestor.
3165 b) Implicit operations that are inherited by the derived type
3166 carry an alias that may be an explicit subprogram (in which case
3167 it may have an Overridden_ Operation indicator) or may also be
3168 inherited and carry its own alias.
3169 c) If the parent type is an interface, the operation of the
3170 derived type does not override, but the interface operation
3171 indicates the operation that implements it.
3172 * sem_prag.adb: Minor reformatting.
3173 * sem_prag.adb (Check_External_Property): Update
3174 the comment on usage. Reimplement.
3176 2016-04-18 Ed Schonberg <schonberg@adacore.com>
3178 * exp_ch5.adb (Expand_Assignment_Statement): In restricted
3179 profiles such as ZFP, ceiling priority is not available.
3181 2016-04-18 Bob Duff <duff@adacore.com>
3183 * namet-sp.ads: Minor typo fix, ironically in 'Spelling_Checker'.
3185 2016-04-18 Bob Duff <duff@adacore.com>
3187 * sem_elab.adb (Output_Calls): Use
3188 Get_Name_String, to clearly indicate that the global Name_Buffer
3189 is being used. The previous code used Is_Internal_Name, which
3190 returns a Boolean, but also has a side effect of setting the
3191 Name_Buffer. Then it called the other Is_Internal_Name, which uses
3192 the Name_Buffer for its input. And then it called Error_Msg_N,
3193 again using the Name_Buffer. We haven't eliminated the global
3194 usage here, but we've made it a bit clearer.
3195 This also allows us to have a side-effect-free version of
3196 Is_Internal_Name.
3197 * namet.ads, namet.adb: Provide a type Bounded_String, along with
3198 routines that can be used without using global variables. Provide
3199 Global_Name_Buffer so existing code can continue to use the
3200 global. Mark the routines that use globals as obsolete. New code
3201 shouldn't call the obsolete ones, and we should clean up existing
3202 code from time to time.
3203 Name_Find_Str is renamed as Name_Find.
3204 * namet.h: Changed as necessary to interface to the new version
3205 of Namet.
3206 * bindgen.adb, exp_unst.adb: Name_Find_Str is renamed as
3207 Name_Find.
3209 2016-04-18 Yannick Moy <moy@adacore.com>
3211 * sem_util.adb, sem_util.ads (Has_Full_Default_Initialization): used
3212 outside of GNATprove, hence it should not be removed.
3214 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
3216 * sem_prag.adb (Analyze_Refinement_Clause):
3217 The refinement of an external abstract state can now mention
3218 non-external constituents.
3219 (Check_External_Property): Update all SPARK RM references.
3221 2016-04-18 Bob Duff <duff@adacore.com>
3223 * exp_intr.adb: Remove some duplicated code.
3225 2016-04-18 Yannick Moy <moy@adacore.com>
3227 * a-nudira.adb, a-nudira.ads, a-nuflra.adb, a-nuflra.ads: Mark
3228 package spec and body out of SPARK.
3230 2016-04-18 Johannes Kanig <kanig@adacore.com>
3232 * spark_xrefs.ads: Minor comment update.
3234 2016-04-18 Johannes Kanig <kanig@adacore.com>
3236 * gnat1drv.adb (Gnat1drv): Force loading of System
3237 unit for SPARK.
3239 2016-04-18 Bob Duff <duff@adacore.com>
3241 * a-cuprqu.adb: Correction to previous change. If a new node
3242 is inserted at the front of the queue (because it is higher
3243 priority than the previous front node), we need to update
3244 Header.Next_Unequal -- not just in the case where the queue was
3245 previously empty.
3247 2016-04-18 Bob Duff <duff@adacore.com>
3249 * a-cuprqu.ads: Change the representation of List_Type from a
3250 singly-linked list to a doubly-linked list. In addition, add a
3251 pointer Next_Unequal, which points past a possibly-long chain
3252 of equal-priority items. This increases efficiency, especially
3253 in the case of many equal-priority items.
3254 * a-cuprqu.adb (Dequeue, Enqueue): Rewrite algorithms to take
3255 advantage of new data structure.
3256 (Finalize): Rewrite in terms of Dequeue, for simplicity.
3258 2016-04-18 Yannick Moy <moy@adacore.com>
3260 * contracts.adb (Analyze_Object_Contract,
3261 Analyze_Protected_Contract): Remove tests performed in GNATprove.
3262 * sem_util.adb, sem_util.ads (Has_Full_Default_Initialization):
3263 Remove query for tests performed in GNATprove.
3265 2016-04-18 Ed Schonberg <schonberg@adacore.com>
3267 * sem_aggr.adb (Resolve_Record_Aggregate): If
3268 Warn_On_Redundant_Constructs is enabled, report a redundant box
3269 association that does not cover any components, as it done for
3270 redundant others associations in case statements.
3272 2016-04-18 Ed Schonberg <schonberg@adacore.com>
3274 * sem_prag.adb (Collect_Inherited_Class_Wide_Conditions):
3275 Analyze the generated Check pragma for an inherited condition so
3276 that it does not freeze the dispatching type of the primitive
3277 operation, because it is pre-analyzed at the point of the
3278 subprogram declaration (and not in the subprogram body, as is
3279 done during regular expansion).
3281 2016-04-18 Vincent Celier <celier@adacore.com>
3283 * ali.ads: Increase the range of all _Id types to 100 millions.
3285 2016-04-18 Gary Dismukes <dismukes@adacore.com>
3287 * sem_warn.adb (Check_References): Change warning to suggest
3288 using pragma Export rather than saying "volatile has no effect".
3290 2016-04-18 Bob Duff <duff@adacore.com>
3292 * g-souinf.ads (Compilation_ISO_Date): New function to return
3293 the current date in ISO form.
3294 * exp_intr.adb (Expand_Source_Info, Add_Source_Info): Expand
3295 a call to Compilation_ISO_Date into a string literal containing
3296 the current date in ISO form.
3297 * exp_intr.ads (Add_Source_Info): Improve documentation.
3298 * sem_intr.adb (Check_Intrinsic_Subprogram): Recognize
3299 Compilation_ISO_Date.
3300 * snames.ads-tmpl (Name_Compilation_ISO_Date): New Name_Id.
3302 2016-04-18 Eric Botcazou <ebotcazou@adacore.com>
3304 * layout.adb (Set_Elem_Alignment): Extend setting of alignment
3305 to subtypes that are not first subtypes.
3307 2016-04-18 Ed Schonberg <schonberg@adacore.com>
3309 * sem_prag.ads (Collect_Inherited_Class_Wide_Conditions):
3310 Simplify interface.
3311 * sem_prag.adb (Collect_Inherited_Class_Wide_Conditions): Insert
3312 generated pragmas after subprogram declaration, rather than in
3313 the corresponding subprogram body.
3314 * sem_ch6.adb (New_Overloaded_Entity): In GNATProve
3315 mode, if the operation is overridding, call
3316 Collect_Inherited_Class_Wide_Conditions to generate the
3317 corresponding pragmas immediately after the corresponding
3318 subprogram declaration.
3320 2016-04-18 Arnaud Charlet <charlet@adacore.com>
3322 * spark_xrefs.ads (Xref_Index, Scope_Index, File_Index): restrict
3323 type to natural numbers.
3324 (Stype): document code characters for concurrent entities.
3326 2016-04-18 Olivier Hainque <hainque@adacore.com>
3328 * targparm.ads: Update the Frontend_Exceptions default internal
3329 value.
3330 (Frontend_Exceptions_On_Target): Change default value to True.
3332 2016-04-18 Ed Schonberg <schonberg@adacore.com>
3334 * sem_ch4.adb (Analyze_Selected_Component): Refine error
3335 detection when a selected component in the body of a synchronized
3336 type is a reference to an object of the same type declared
3337 elsewhere. The construct is legal if the prefix of the selected
3338 component includes an explicit dereference at any point.
3340 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
3342 * sem_ch3.adb (Analyze_Object_Declaration): Do not consider
3343 internally generated expressions when trying to determine whether
3344 a formal parameter of a tagged type subject to Extensions_Visible
3345 False is used to initialize an object.
3346 * sem_ch4.adb (Analyze_Type_Conversion): Do not consider
3347 internally generated expressions when trying to determine whether
3348 a formal parameter of a tagged type subject to Extensions_Visible
3349 False is used in a type conversion.
3351 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
3353 * sem_res.adb (Is_Protected_Operation_Call):
3354 Add guards to account for a non-decorated selected component.
3356 2016-04-18 Yannick Moy <moy@adacore.com>
3358 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Improve
3359 implementation of Body_Has_SPARK_Mode_On.
3360 * sem_prag.adb, sem_prag.ads (Get_SPARK_Mode_From_Annotation):
3361 New function replacing previous Get_SPARK_Mode_From_Pragma, that
3362 deals also with aspects.
3363 (Get_SPARK_Mode_Type): Make function internal again.
3364 * inline.adb, sem_ch7.adb, sem_util.adb: Use new
3365 Get_SPARK_Mode_From_Annotation.
3367 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
3369 * contracts.adb (Analyze_Object_Contract): Update references to
3370 SPARK RM.
3371 * freeze.adb (Freeze_Entity): Update references to SPARK RM.
3372 * ghost.adb Add with and use clauses for Sem_Disp.
3373 (Check_Ghost_Derivation): Removed.
3374 (Check_Ghost_Overriding):
3375 Reimplemented. (Check_Ghost_Policy): Update references to SPARK RM.
3376 (Check_Ghost_Primitive): New routine.
3377 (Check_Ghost_Refinement): New routine. (Is_OK_Ghost_Context):
3378 Update references to SPARK RM. (Is_OK_Pragma): Update references
3379 to SPARK RM. Predicates are now a valid context for references
3380 to Ghost entities.
3381 * ghost.ads (Check_Ghost_Derivation): Removed.
3382 (Check_Ghost_Overriding): Update the comment on usage.
3383 (Check_Ghost_Primitive): New routine.

3386 * sem_ch3.adb (Process_Full_View): Remove the now obsolete check
3387 related to Ghost derivations
3388 * sem_ch6.adb (Check_Conformance): Remove now obsolete check
3389 related to the convention-like behavior of pragma Ghost.
3390 (Check_For_Primitive_Subprogram): Verify that the Ghost policy
3391 of a tagged type and its primitive agree.
3392 * sem_prag.adb (Analyze_Pragma): Update references to SPARK
3393 RM. Move the verification of pragma Assertion_Policy Ghost
3394 to the proper place. Remove the now obsolete check related
3395 to Ghost derivations.
3396 (Collect_Constituent): Add a call to Check_Ghost_Refinement.
3397 * sem_res.adb (Resolve_Actuals): Update references to SPARK RM.
3399 2016-04-18 Eric Botcazou <ebotcazou@adacore.com>
3401 * layout.adb: Fix more minor typos in comments.
3403 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
3405 * a-calend.ads, sem_prag.adb, sem_ch6.adb: Minor reformatting.
3407 2016-04-18 Ed Schonberg <schonberg@adacore.com>
3409 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): In GNATprove
3410 mode, collect inherited class-wide conditions to generate the
3411 corresponding pragmas.
3412 * sem_prag.ads (Build_Pragma_Check_Equivalent): Moved from contracts
3413 * contracts.adb (Collect_Inherited_Class_Wide_Conditions): New
3414 procedure for overriding subprograms, used to generate the pragmas
3415 corresponding to an inherited class- wide pre- or postcondition.
3416 * sem_prag.adb (Build_Pragma_Check_Equivalent): moved here
3417 from contracts.adb (Replace_Condition_Entities): Subsidiary
3418 Build_Pragma_Check_Equivalent, to implement the proper semantics
3419 of inherited class-wide conditions, as given in AI12-0113.
3420 (Process_Class_Wide_Condition): Removed.
3421 (Collect_Inherited_Class_Wide_Conditions): Iterate over pragmas
3422 in contract of subprogram, to collect inherited class-wide
3423 conditions.
3424 (Build_Pragma_Check_Equivalent): Moved to sem_prag.adb
3426 2016-04-18 Yannick Moy <moy@adacore.com>
3428 * a-calend.adb (Ada.Calendar): Mark package body as SPARK_Mode Off.
3429 * a-calend.ads (Ada.Calendar): Mark package spec as
3430 SPARK_Mode and add synchronous external abstract state Clock_Time.
3432 2016-04-18 Yannick Moy <moy@adacore.com>
3434 * sem_res.adb (Resolve_Call): Prevent inlining of
3435 calls inside expression functions. Factor previous code issuing
3436 errors to call Cannot_Inline instead, which does appropriate
3437 processing of message for GNATprove.
3439 2016-04-18 Arnaud Charlet <charlet@adacore.com>
3441 * einfo.ads, sem_ch3.adb, sem_ch8.adb, osint-l.adb, rtsfind.adb,
3442 osint-b.adb: Cleanups.
3444 2016-04-18 Yannick Moy <moy@adacore.com>
3446 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Only create
3447 body to inline in GNATprove mode when SPARK_Mode On applies to
3448 subprogram body.
3449 * sem_prag.adb, sem_prag.ads (Get_SPARK_Mode_Type): Make function
3450 public.
3452 2016-04-18 Eric Botcazou <ebotcazou@adacore.com>
3454 * layout.adb: Fix minor typo in comment.
3455 * inline.adb: Fix minor pasto.
3456 * sem_ch12.ads: Fix minor typos in comments.
3458 2016-04-18 Ed Schonberg <schonberg@adacore.com>
3460 * sem_disp.adb (Check_Dispatching_Call): Major rewriting to
3461 handle some complex cases of tag indeterminate calls that are
3462 actuals in other dispatching calls that are themselves tag
3463 indeterminate.
3464 (Check_Dispatching_Context): Add parameter to support recursive
3465 check for an enclosing construct that may provide a tag for a
3466 tag-indeterminate call.
3468 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
3470 * sem_prag.adb (Analyze_Depends_In_Decl_Part):
3471 Add global variables Task_Input_Seen and Task_Output_Seen.
3472 (Analyze_Global_Item): Detect an illegal use of the current
3473 instance of a single protected/task type in a global annotation.
3474 (Analyze_Input_Output): Inputs and output related to the current
3475 instance of a task unit are now tracked.
3476 (Check_Usage): Require
3477 the presence of the current instance of a task unit only when
3478 one input/output is available. (Current_Task_Instance_Seen):
3479 New routine.
3480 (Is_CCT_Instance): New parameter profile. Update
3481 the comment on usage. The routine now properly recognizes several
3482 cases related to single protected/task types.
3484 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
3486 * freeze.adb (Freeze_Entity): Use New_Freeze_Node
3487 to create a brand new freeze node. This handles a case where an
3488 ignored Ghost context is freezing something which is not ignored
