26 * gnat_rm.texi, gnat_ugn.texi: Regenerated.
28 2017-01-13 Ed Schonberg <schonberg@adacore.com>
30 * einfo.ads: minor grammar fixes in comment of Normalized_Position_Max.
31 * scil_ll.adb: Minor style fix in comment.
32 * sem_ch8.adb (Analyze_Expanded_Name): Perform dimension analysis
33 even if entity is already set, because the node may be renalyzed
34 after inlining transformations.
36 2017-01-13 Javier Miranda <miranda@adacore.com>
38 * sem_res.adb (Resolve_Call): Do not establish a transient scope
39 for a call to inlinable expression function (since the call will
40 be replaced by its returned object).
41 * exp_ch6.ads (Is_Inlinable_Expression_Function): New subprogram.
42 * exp_ch6.adb (Expression_Of_Expression_Function): New subprogram.
43 (Expand_Call): For inlinable expression function call replace the

49 * checks.adb: Minor typo fix and reformatting.
51 2017-01-13 Javier Miranda <miranda@adacore.com>
53 * contracts.adb (Contract_Only_Subprograms): Remove formal.
54 (Copy_Original_Specification): Removed.
55 (Skip_Contract_Only_Subprogram): Move here checks previously
56 located in the caller of this routine (to leave the code more clean).
57 (Build_Contract_Only_Subprogram): Code cleanup.
58 * scil_ll.ads, scil_ll.adb (Get_Contract_Only_Body_Name): Removed.
59 (Get_Contract_Only_Missing_Body_Name): Removed.
61 2017-01-13 Javier Miranda <miranda@adacore.com>
63 * sem_ch6.adb (Cloned_Expression): New subprogram.
64 (Freeze_Expr_Types): Complete previous patch since the expression
65 of an expression-function may have iterators and loops with
66 defining identifiers which, as part of the preanalysis of the
67 expression, may be left decorated with itypes that will not be
68 available in the tree passed to the backend.
70 2017-01-13 Ed Schonberg <schonberg@adacore.com>
72 * checks.adb (Apply_Type_Conversion_Checks): Optimize a type
73 conversion to Integer of an expression that is an attribute
74 reference 'Pos on an enumeration type.

83 calls in accessibility check on return statement.
85 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
87 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
88 Ensure that the input body is a subprogram body before trying to
89 determine whether it denoted an expression function. Note that
90 subprogram body stubs cannot denote expression functions.
92 2017-01-13 Gary Dismukes <dismukes@adacore.com>
94 * bindgen.adb, sem_ch6.adb, binde.adb, exp_ch3.adb: Minor reformatting

99 * einfo.ads (Component_Bit_Offset): Fix documentation.
100 * sem_ch13.adb (Check_Record_Representation_Clause): Skip check
101 on record holes for components with unknown compile-time offsets.

106 * g-locfil.ads: Minor comment fix.
108 2017-01-13 Bob Duff <duff@adacore.com>
110 * binde.adb (Elab_New): New elaboration order algorithm
111 that is expected to cause fewer ABE issues. This is a work in
112 progress. The new algorithm is currently disabled, and can be
113 enable by the -dp switch, or by modifying the Do_Old and Do_New
114 etc. flags and rebuilding. Experimental code is included to
115 compare the results of the old and new algorithms.
116 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
117 can have multiple of these tables, so the old and new algorithms
119 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
120 parameter of type array. This avoids the global variable, and
121 allows bounds checking (which is normally defeated by the tables
122 packages). It also ensures that the Elab_Order is read-only
124 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
125 subprograms that need it, as above.
126 * debug.adb: Document new -dp switch. Modify doc of old -do
128 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
129 and Bindgen. Move writing of closure (-R and -Ra switches)
130 to Binde; that's more convenient.
132 2017-01-13 Ed Schonberg <schonberg@adacore.com>
134 * sem_ch6.adb (Analyze_Expression_Function): If the expression
135 function is a completion, all entities referenced in the
136 expression are frozen. As a consequence, a reference to an
137 uncompleted private type from an enclosing scope is illegal.
139 2017-01-13 Javier Miranda <miranda@adacore.com>
141 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
142 (Analyze_Subprogram_Body_Helper): At the occurrence of an
143 expression function declaration that is a completion, its
144 expression causes freezing (AI12-0103).
146 2017-01-13 Vadim Godunko <godunko@adacore.com>
148 * a-coinho-shared.adb: Fix memory leaks in Constant_Reference and
149 Reference functions of Ada.Containers.Indefinite_Holders.
151 2017-01-13 Bob Duff <duff@adacore.com>
153 * s-os_lib.ads: Minor comment fixes.
155 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
157 * exp_ch3.adb (Default_Initialize_Object): Do not default
158 initialize an object when it is of a task type and restriction
159 No_Tasking is in effect because the initialization is obsolete.
160 * exp_ch9.adb (Build_Master_Entity): Do not generate a master when
161 restriction No_Tasking is in effect.
162 (Build_Master_Renaming): Do not rename a master when restriction
163 No_Tasking is in effect.
165 2017-01-13 Ed Schonberg <schonberg@adacore.com>
167 * sem_aggr.adb (Resolve_Array_Aggregate): The code that verifies
168 the legality of An others clause applies as well to a choice in
169 an Iterated_component_ association.
170 (Resolve_Iterated_Component_Association): An others choice
172 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An
173 Iterated_Component_Association is not static.
175 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
177 * exp_ch3.adb (Freeze_Type): Mark the Ghost mode as set in case
178 control is passed to the expresion handler before the new mode
180 * sem_ch12.adb (Analyze_Package_Instantiation,
181 Analyze_Subprogram_Instantiation): Mark the Ghost mode as set
182 in case control is passed to the expresion handler before the

187 * sem_aggr.adb, sem_ch3.adb, inline.adb, sem_util.adb, exp_ch4.adb,
188 exp_aggr.adb: Minor reformatting.
190 2017-01-13 Gary Dismukes <dismukes@adacore.com>
192 * inline.adb: Minor reformatting and typo fix.
194 2017-01-13 Ed Schonberg <schonberg@adacore.com>
196 * sem_util.ads, sem_util.adb (Choice_List): Move function here
197 from sem_aggr.adb, for use elsewhere.
198 * sem_ch3.adb (Analyze_Object_Declaration): Use Choice_List.
199 * sem_aggr.adb (Resolve_Array_Aggregate): Remove
200 Iterated_Component_Present.
201 * exp_aggr.adb: Use Choice_List throughout, to handle
202 Iterated_Component_Associations.
203 (Gen_Loop): Generate proper loop for an
204 Iterated_Component_Association: loop variable has the identifier
205 of the original association. Generate a loop even for a single
206 component choice, in order to make loop parameter visible in
208 (Flatten): An Iterated_Component_Association is not static.
210 2017-01-13 Yannick Moy <moy@adacore.com>
212 * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
213 float exponentiation for statically known small negative values
214 is the reciprocal of the exponentiation for the opposite value
216 * s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):
217 Ensure that the value of float exponentiation for negative values
218 is the reciprocal of the exponentiation for the opposite value
220 * inline.adb (Expand_Inlined_Call): Fix the count
221 for the number of generated gotos.
223 2017-01-13 Yannick Moy <moy@adacore.com>

227 expression in delay statement as OK for volatile context.
229 2017-01-13 Ed Schonberg <schonberg@adacore.com>
231 * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
232 mode a choice that is a subtype with a static predicate is
233 replaced by the values it covers. This transformation must not
234 be performed in ASIS mode, to preserve the source for analysis.
236 2017-01-13 Justin Squirek <squirek@adacore.com>
238 * nlists.ads: Correct minor typo.
240 2017-01-13 Gary Dismukes <dismukes@adacore.com>
242 * sem_ch13.adb: Minor reformatting and typo fix.
244 2017-01-13 Ed Schonberg <schonberg@adacore.com>
246 * par-ch4.adb (P_Aggregate_Or_Parent_Expr): An
247 Iterated_Component_Association is a named association in an
249 * sem_aggr.adb (Resolve_Iterated_Component_Association): New
250 procedure, subsidiary of Resolve_Array_Aggregate, to analyze
251 and resolve the discrete choices and the expression of the
253 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
254 Loop_Actions and Box_Present are attributes of
255 N_Iterated_Component_Association nodes. Box_Present is always
257 * sprint.adb (Sprint_Node): An Iterated_Component_Association
258 has a Discrete_Choices list, as specified in the RM. A
259 Component_Association for aggregate uses instead a Choices list.
260 We have to live with this small inconsistency because the new
261 construct also has a defining identifier, and there is no way
262 to merge the two node structures.
264 2017-01-13 Yannick Moy <moy@adacore.com>
266 * inline.adb (Remove_Aspects_And_Pragmas): Add Unused to the
267 list of pragmas to remove. Remove pragmas from the list of
268 statements in the body to inline.
269 * namet.adb, namet.ads (Nam_In): New version with 12 parameters.
271 2017-01-13 Ed Schonberg <schonberg@adacore.com>
273 * sem_ch3.adb (Resolve_Aspects): New procedure, subsidiary of
274 Analyze_Declarations, to analyze and resolve the expressions of
275 aspect specifications in the current declarative list, so that
276 the expressions have proper entity and type info. This is needed
277 for ASIS when there is no subsequent expansion to generate this
278 semantic information.
279 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
280 original expression, to suppress cascaded errors when expression
281 has been constant-folded.
282 (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
283 ASIS mode, because there is no subsequent expansion to decorate
286 2017-01-13 Yannick Moy <moy@adacore.com>
288 * inline.adb, inline.ads (Call_Can_Be_Inlined_In_GNATprove_Mode):
289 New function to detect when a call may be inlined or not in
291 (Expand_Inlined_Call): Ensure that a temporary
292 is always created in the cases where a type conversion may be
293 needed on an input parameter in GNATprove mode, so that GNATprove
294 sees the check to perform.
295 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
296 when not applicable due to actual requiring type conversion
297 with possible check but no temporary value can be copied for
298 GNATprove to see the check.

394 treat comparisons on strings as legal in a Static_Predicate.
395 (Is_Predicate_Static, Is_Type_Ref): Predicate also returns true on
396 a function call that is the expansion of a string comparison.The
397 function call is built when compiling the corresponding predicate
398 function, but the expression has been found legal as a static
399 predicate during earlier analysis.
400 * sem_eval.adb (Real_Or_String_Static_Predicate_Matches): Handle
401 properly a function call that is the expansion of a string

429 2017-01-13 Javier Miranda <miranda@adacore.com>
431 * sem_res.adb (Resolve_Generalized_Indexing): Compiling in ASIS mode,

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

481 * sem_attr.adb (Analyze_Attribute): In GNATprove_Mode, for the
482 four attributes identified in SRM 9(18), add an implicit with
483 to Ada.Task_Identification.
484 * sem_ch8.adb (Analyze_Subprogram_Renaming.Build_Class_Wide_Wrapper):
485 Deal specially with the wrapper introduced for AI05-0071 in GNATprove
487 * checks.adb (Apply_Discriminant_Check,
488 Apply_Selected_Length_Checks, Apply_Selected_Range_Checks):
489 In GNATprove mode, we do not apply the checks, but we still
