   4         Minor reformatting.
   5
   6 2018-01-11  Justin Squirek  <squirek@adacore.com>
   7
   8         * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
   9         to make sure a given expression function is properly parenthesized.
  10
  11 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
  12
  13         * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Check the
  14         categorization of a subprogram body which does not complete a previous
  15         declaration.
  16
  17 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
  18
  19         * sem_ch10.adb (Check_Private_Child_Unit): Ensure that the enclosing
  20         scope of package Ada is Standard.
  21
  22 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
  23
  24         * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
  25         subcomponent of the current entity when building the body for a dynamic
  26         predicate function for a record with composite subcomponents.
  27
  28 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
  29
  30         * exp_aggr.adb (Convert_Aggr_In_Object_Decl): Update the call to
  31         Establish_Transient_Scope.
  32         (Convert_To_Assignments): Update the call to Establish_Transient_Scope.
  33         (Expand_Array_Aggregate): Update the call to Establish_Transient_Scope.
  34         * exp_ch6.adb (Expand_Call_Helper): Update the call to
  35         Establish_Transient_Scope.
  36         (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
  37         Establish_Transient_Scope.
  38         * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
  39         management of the secondary stack to an enclosing scope if there is no
  40         suitable construct to wrap, and the transient scope was intended to
  41         manage the secondary stack.
  42         (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
  43         is a valid boundary for a transient expression which comes from the
  44         statements of the alternative, otherwise alternatives cannot be
  45         wrapped. Assignments of controlled objects which have controlled
  46         actions suppressed now stop the traversal as there is no point in
  47         looking for an enclosing construct. Add several N_xxx_Body choices to
  48         the termination conditions for completeness.
  49         * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
  50         and the associated comment on usage.
  51         * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
  52         Establish_Transient_Scope.
  53         (Add_Write_After): Update the call to Establish_Transient_Scope.
  54         * sem_res.adb (Check_Initialization_Call): Removed.
  55         (Resolve_Actuals): Account for additional cases where finalization
  56         actions are required by utilizing predicate Needs_Finalization rather
  57         than Is_Controlled.
  58         (Resolve_Call): Type initialization procedures can now utilize
  59         transient scopes to manage the secondary stack, thus preventing leaks
  60         during initialization.  Remove the previous kludgy algorithm which
  61         attempts to manage the secondary stack at the object creation site.
  62
  63 2018-01-11  Jerome Lambourg  <lambourg@adacore.com>
  64
  65         * libgnat/g-soliop__qnx.ads: New.
  66         * adaint.c, adaint.h, cstreams.c, s-oscons-tmplt.c, sysdep.c: Update
  67         for QNX.
  68
  69 2018-01-11  Bob Duff  <duff@adacore.com>
  70
  71         * par-ch9.adb (P_Protected_Operation_Declaration_Opt): Give an error if
  72         a null procedure occurs in a protected definition.
  73
  74 2018-01-11  Bob Duff  <duff@adacore.com>

  81         xml2gnat.
  82
  83 2018-01-11  Bob Duff  <duff@adacore.com>
  84
  85         * binde.adb (Force_Elab_Order): Give an error if there are duplicate
  86         unit names.
  87
  88 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
  89
  90         * sem_ch6.adb (Freeze_Expr_Types): If an access value is the
  91         controlling argument of a dispatching call. freeze the corresponding
  92         designated type.
  93
  94 2018-01-11  Ben Brosgol  <brosgol@adacore.com>
  95
  96         * doc/Makefile: Add Sphinx option -W to treat warnings as errors.
  97
  98 2018-01-11  Ben Brosgol  <brosgol@adacore.com>

 100         * doc/gnat_rm/implementation_defined_aspects.rst: Minor type/wording
 101         corrections.
 102         * gnat_rm.texi: Regenerate.
 103
 104 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
 105
 106         * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
 107         formsl type corresponding to the actual fixed point type is private,
 108         because in this case there can be no suspicious arithmetic operations
 109         in the generic unless they reference a formal subprogram.  Clarify
 110         warning.
 111
 112 2018-01-11  Javier Miranda  <miranda@adacore.com>
 113
 114         * exp_util.adb (Remove_Side_Effects): No action done for functions
 115         returning class-wide types since it requires generating code using
 116         'reference and the CCG target has no secondary stack.
 117         * gnat1drv.adb: Disable building static dispatch tables when generating
 118         C code.
 119
 120 2018-01-11  Piotr Trojanek  <trojanek@adacore.com>
 121
 122         * libgnat/a-direio.ads, libgnat/a-sequio.ads, libgnat/a-ststio.ads,

 134         * doc/gnat_ugn/about_this_guide.rst: Update reference.
 135
 136 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 137
 138         * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
 139         if it contains at least one component declaration employing a function
 140         call returning on the secondary stack.
 141
 142 2018-01-11  Yannick Moy  <moy@adacore.com>
 143
 144         * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:

 150         * doc/gnat_ugn/gnat_utility_programs.rst: Fix layout.
 151
 152 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 153
 154         * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
 155         sem_res.adb, sem_util.adb: Minor reformatting.
 156
 157 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
 158
 159         * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
 160         has a delayed aspect which must be processed at the point the type is
 161         frozen. This mimics what is done when the predicate is provided by a
 162         source aspect.
 163
 164 2018-01-11  Doug Rupp  <rupp@adacore.com>
 165
 166         * init.c (vxworks): Add macro checks for __aarch64__.
 167
 168 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 169
 170         * exp_util.adb (Add_Failure_Expression): New routine.
 171         (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
 172         * sem_util.adb (Is_Current_Instance): Code cleanup.
 173
 174 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
 175
 176         * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
 177         Default_Sec_Stack_Size.
 178         * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
 179         limit check so that the integer index does not overflow. Check the
 180         dynamic stack allocation does not cause the secondary stack pointer to
 181         overflow.
 182         (SS_Info): Align colons.
 183         (SS_Init): Cover the case when bootstraping with an old compiler that
 184         does not set Default_SS_Size.
 185
 186 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
 187
 188         * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
 189         legality of an inherited operation that may require overriding, ignore
 190         primitive_wrappers that correspond to explicit operations that override
 191         an interface primitive.
 192         * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
 193         operation to which the class-wide expression applies is a protected op.
 194         with a primitive_wrapper, verify that the updated inherited expression
 195         does not contain an internal call to a protected function.  This
 196         completes the implementation of AI12-0166.
 197
 198 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 199
 200         * ali.adb: Document the remaining letters available for ALI lines.
 201         (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
 202         * ali.ads: Update type With_Record. Field
 203         Implicit_With_From_Instantiation is no longer in use. Add field
 204         Implicit_With.
 205         * csinfo.adb (CSinfo): Remove the setup for attribute
 206         Implicit_With_From_Instantiation.
 207         * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
 208         either implicitly or explicitly withed.
 209         (Is_Implicit_With_Clause): New routine.
 210         (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
 211         confusion with the with clause attribute by the same name.
 212         (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
 213         * rtsfind.adb (Maybe_Add_With): Code cleanup.
 214         * sem_ch8.adb (Present_System_Aux): Code cleanup.
 215         * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
 216         for a parent unit.
 217         (Implicit_With_On_Parent): Mark the with clause as generated for a
 218         parent unit.
 219         * sem_ch12.adb (Inherit_Context): With clauses inherited by an
 220         instantiation are no longer marked as Implicit_With_From_Instantiation
 221         because they are already marked as implicit.
 222         * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
 223         which marks implicit with clauses as related to an instantiation.
 224         * sinfo.adb (Implicit_With_From_Instantiation): Removed.
 225         (Parent_With): New routine.
 226         (Set_Implicit_With_From_Instantiation): Removed.
 227         (Set_Parent_With): New routine.
 228         * sinfo.ads: Update the documentation of attribute Implicit_With.
 229         Remove attribute Implicit_With_From_Instantiation along with
 230         occurrences in nodes.  Add attribute Parent_With along with occurrences
 231         in nodes.
 232         (Implicit_With_From_Instantiation): Removed along with pragma Inline.
 233         (Parent_With): New routine along with pragma Inline.
 234         (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
 235         (Set_Parent_With): New routine along with pragma Inline.
 236
 237 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 238
 239         * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
 240         entity when the enclosing construct is a body.
 241
 242 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
 243
 244         * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
 245         Secondary_Stack_Size handling as a pragma is now generated for the
 246         corresponding aspect instead of an attribute.  Pragma expression is
 247         relocated instead of evaluated. Discriminant of the corresponding
 248         record type is referenced rather than the type discriminant.
 249         (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
 250         Secondary_Stack_Size rep item checks to only look for the pragma rep.
 251         * sem_ch13.adb (Analyze_One_Aspect): Transform
 252         Aspect_Secondary_Stack_Size into a pragma instead of an attribute
 253         because the attribute does not have visibility on a task type's
 254         discriminants when the type's definition is expanded.
 255         (Analyze_Attribute_Definition_Clause): Remove handling of
 256         Attribute_Secondary_Stack_Size.
 257         * snames.adb-tmpl, snames.ads-tmpl: Remove
 258         Attribute_Secondary_Stack_Size, no longer used.
 259
 260 2018-01-11  Justin Squirek  <squirek@adacore.com>
 261
 262         * sem_ch8.adb: Minor comment fix.
 263
 264 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 265
 266         * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
 267         individual action because the action may denote a complex expression,
 268         such as a case statement, which in turn may contain additional
 269         transient objects.
 270
 271 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
 272
 273         * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
 274         analysis on a copy of the expression with a copy of the index variable,
 275         because full expansion will rewrite construct into a loop with the
 276         original loop variable.
 277         * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
 278         expression is an iterated component association. Full analysis takes
 279         place when construct is rewritten as a loop.
 280         (In_Place_Assign_OK, Safe_Component): An iterated_component_association
 281         is not safe for in-place assignment.
 282         * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
 283         entity with no homonym and no other entity in the scope.
 284
 285 2018-01-11  Justin Squirek  <squirek@adacore.com>
 286
 287         * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
 288         message to be printed on the pragma argument identifier.
 289
 290 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 291
 292         * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
 293         entity of the generated invariant procedure in order to construct a
 294         proper entity chain.
 295
 296 2018-01-11  Piotr Trojanek  <trojanek@adacore.com>
 297
 298         * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in

 304         Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
 305         Allow E_Discriminant.
 306
 307 2018-01-10  Eric Botcazou  <ebotcazou@adacore.com>
 308
 309         * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
 310         for atomic access once the component size is taken into account and
 311         also do it if the component type is Atomic or Volatile_Full_Access.
 312
 313 2018-01-04  Eric Botcazou  <ebotcazou@adacore.com>
 314
 315         * gnatvsn.ads: Bump copyright year.
