   1 2018-01-11  Justin Squirek  <squirek@adacore.com>
   2
   3         * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
   4         to make sure a given expression function is properly parenthesized.
   5
   6 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
   7
   8         * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Check the
   9         categorization of a subprogram body which does not complete a previous
  10         declaration.
  11
  12 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
  13
  14         * sem_ch10.adb (Check_Private_Child_Unit): Ensure that the enclosing
  15         scope of package Ada is Standard.
  16
  17 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
  18
  19         * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
  20         subcomponent of the current entity when building the body for a dynamic
  21         predicate function for a record with composite subcomponents.
  22
  23 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
  24
  25         * exp_aggr.adb (Convert_Aggr_In_Object_Decl): Update the call to
  26         Establish_Transient_Scope.
  27         (Convert_To_Assignments): Update the call to Establish_Transient_Scope.
  28         (Expand_Array_Aggregate): Update the call to Establish_Transient_Scope.
  29         * exp_ch6.adb (Expand_Call_Helper): Update the call to
  30         Establish_Transient_Scope.
  31         (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
  32         Establish_Transient_Scope.
  33         * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
  34         management of the secondary stack to an enclosing scope if there is no
  35         suitable construct to wrap, and the transient scope was intended to
  36         manage the secondary stack.
  37         (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
  38         is a valid boundary for a transient expression which comes from the
  39         statements of the alternative, otherwise alternatives cannot be
  40         wrapped. Assignments of controlled objects which have controlled
  41         actions suppressed now stop the traversal as there is no point in
  42         looking for an enclosing construct. Add several N_xxx_Body choices to
  43         the termination conditions for completeness.
  44         * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
  45         and the associated comment on usage.
  46         * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
  47         Establish_Transient_Scope.
  48         (Add_Write_After): Update the call to Establish_Transient_Scope.
  49         * sem_res.adb (Check_Initialization_Call): Removed.
  50         (Resolve_Actuals): Account for additional cases where finalization
  51         actions are required by utilizing predicate Needs_Finalization rather
  52         than Is_Controlled.
  53         (Resolve_Call): Type initialization procedures can now utilize
  54         transient scopes to manage the secondary stack, thus preventing leaks
  55         during initialization.  Remove the previous kludgy algorithm which
  56         attempts to manage the secondary stack at the object creation site.
  57
  58 2018-01-11  Jerome Lambourg  <lambourg@adacore.com>
  59
  60         * libgnat/g-soliop__qnx.ads: New.
  61         * adaint.c, adaint.h, cstreams.c, s-oscons-tmplt.c, sysdep.c: Update
  62         for QNX.
  63
  64 2018-01-11  Bob Duff  <duff@adacore.com>
  65
  66         * par-ch9.adb (P_Protected_Operation_Declaration_Opt): Give an error if
  67         a null procedure occurs in a protected definition.
  68
  69 2018-01-11  Bob Duff  <duff@adacore.com>

  76         xml2gnat.
  77
  78 2018-01-11  Bob Duff  <duff@adacore.com>
  79
  80         * binde.adb (Force_Elab_Order): Give an error if there are duplicate
  81         unit names.
  82
  83 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
  84
  85         * sem_ch6.adb (Freeze_Expr_Types): If an access value is the
  86         controlling argument of a dispatching call. freeze the corresponding
  87         designated type.
  88
  89 2018-01-11  Ben Brosgol  <brosgol@adacore.com>
  90
  91         * doc/Makefile: Add Sphinx option -W to treat warnings as errors.
  92
  93 2018-01-11  Ben Brosgol  <brosgol@adacore.com>
  94
  95         * doc/gnat_rm/implementation_defined_aspects.rst: Minor type/wording
  96         corrections.
  97         * gnat_rm.texi: Regenerate.
  98
  99 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
 100
 101         * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
 102         formsl type corresponding to the actual fixed point type is private,
 103         because in this case there can be no suspicious arithmetic operations
 104         in the generic unless they reference a formal subprogram.  Clarify
 105         warning.
 106
 107 2018-01-11  Javier Miranda  <miranda@adacore.com>
 108
 109         * exp_util.adb (Remove_Side_Effects): No action done for functions
 110         returning class-wide types since it requires generating code using
 111         'reference and the CCG target has no secondary stack.
 112         * gnat1drv.adb: Disable building static dispatch tables when generating
 113         C code.
 114
 115 2018-01-11  Piotr Trojanek  <trojanek@adacore.com>
 116
 117         * libgnat/a-direio.ads, libgnat/a-sequio.ads, libgnat/a-ststio.ads,

 126
 127         * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
 128         to match what the Libadalang-based version does.
 129         * doc/gnat_ugn/about_this_guide.rst: Update reference.
 130
 131 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 132
 133         * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
 134         if it contains at least one component declaration employing a function
 135         call returning on the secondary stack.
 136
 137 2018-01-11  Yannick Moy  <moy@adacore.com>
 138
 139         * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:

 144
 145         * doc/gnat_ugn/gnat_utility_programs.rst: Fix layout.
 146
 147 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 148
 149         * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
 150         sem_res.adb, sem_util.adb: Minor reformatting.
 151
 152 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
 153
 154         * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
 155         has a delayed aspect which must be processed at the point the type is
 156         frozen. This mimics what is done when the predicate is provided by a
 157         source aspect.
 158
 159 2018-01-11  Doug Rupp  <rupp@adacore.com>
 160
 161         * init.c (vxworks): Add macro checks for __aarch64__.
 162
 163 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 164
 165         * exp_util.adb (Add_Failure_Expression): New routine.
 166         (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
 167         * sem_util.adb (Is_Current_Instance): Code cleanup.
 168
 169 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
 170
 171         * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
 172         Default_Sec_Stack_Size.
 173         * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
 174         limit check so that the integer index does not overflow. Check the
 175         dynamic stack allocation does not cause the secondary stack pointer to
 176         overflow.
 177         (SS_Info): Align colons.
 178         (SS_Init): Cover the case when bootstraping with an old compiler that
 179         does not set Default_SS_Size.
 180
 181 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
 182
 183         * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
 184         legality of an inherited operation that may require overriding, ignore
 185         primitive_wrappers that correspond to explicit operations that override
 186         an interface primitive.
 187         * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
 188         operation to which the class-wide expression applies is a protected op.
 189         with a primitive_wrapper, verify that the updated inherited expression
 190         does not contain an internal call to a protected function.  This
 191         completes the implementation of AI12-0166.
 192
 193 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 194
 195         * ali.adb: Document the remaining letters available for ALI lines.
 196         (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
 197         * ali.ads: Update type With_Record. Field
 198         Implicit_With_From_Instantiation is no longer in use. Add field
 199         Implicit_With.
 200         * csinfo.adb (CSinfo): Remove the setup for attribute
 201         Implicit_With_From_Instantiation.
 202         * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
 203         either implicitly or explicitly withed.
 204         (Is_Implicit_With_Clause): New routine.
 205         (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
 206         confusion with the with clause attribute by the same name.
 207         (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
 208         * rtsfind.adb (Maybe_Add_With): Code cleanup.
 209         * sem_ch8.adb (Present_System_Aux): Code cleanup.
 210         * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
 211         for a parent unit.
 212         (Implicit_With_On_Parent): Mark the with clause as generated for a
 213         parent unit.
 214         * sem_ch12.adb (Inherit_Context): With clauses inherited by an
 215         instantiation are no longer marked as Implicit_With_From_Instantiation
 216         because they are already marked as implicit.
 217         * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
 218         which marks implicit with clauses as related to an instantiation.
 219         * sinfo.adb (Implicit_With_From_Instantiation): Removed.
 220         (Parent_With): New routine.
 221         (Set_Implicit_With_From_Instantiation): Removed.
 222         (Set_Parent_With): New routine.
 223         * sinfo.ads: Update the documentation of attribute Implicit_With.
 224         Remove attribute Implicit_With_From_Instantiation along with
 225         occurrences in nodes.  Add attribute Parent_With along with occurrences
 226         in nodes.
 227         (Implicit_With_From_Instantiation): Removed along with pragma Inline.
 228         (Parent_With): New routine along with pragma Inline.
 229         (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
 230         (Set_Parent_With): New routine along with pragma Inline.
 231
 232 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 233
 234         * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
 235         entity when the enclosing construct is a body.
 236
 237 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
 238
 239         * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
 240         Secondary_Stack_Size handling as a pragma is now generated for the
 241         corresponding aspect instead of an attribute.  Pragma expression is
 242         relocated instead of evaluated. Discriminant of the corresponding
 243         record type is referenced rather than the type discriminant.
 244         (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
 245         Secondary_Stack_Size rep item checks to only look for the pragma rep.
 246         * sem_ch13.adb (Analyze_One_Aspect): Transform
 247         Aspect_Secondary_Stack_Size into a pragma instead of an attribute
 248         because the attribute does not have visibility on a task type's
 249         discriminants when the type's definition is expanded.
 250         (Analyze_Attribute_Definition_Clause): Remove handling of
 251         Attribute_Secondary_Stack_Size.
 252         * snames.adb-tmpl, snames.ads-tmpl: Remove
 253         Attribute_Secondary_Stack_Size, no longer used.
 254
 255 2018-01-11  Justin Squirek  <squirek@adacore.com>
 256
 257         * sem_ch8.adb: Minor comment fix.
 258
 259 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 260
 261         * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
 262         individual action because the action may denote a complex expression,
 263         such as a case statement, which in turn may contain additional
 264         transient objects.
 265
 266 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
 267
 268         * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
 269         analysis on a copy of the expression with a copy of the index variable,
 270         because full expansion will rewrite construct into a loop with the
 271         original loop variable.
 272         * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
 273         expression is an iterated component association. Full analysis takes
 274         place when construct is rewritten as a loop.
 275         (In_Place_Assign_OK, Safe_Component): An iterated_component_association
 276         is not safe for in-place assignment.
 277         * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
 278         entity with no homonym and no other entity in the scope.
 279
 280 2018-01-11  Justin Squirek  <squirek@adacore.com>
 281
 282         * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
 283         message to be printed on the pragma argument identifier.
 284
 285 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 286
 287         * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
 288         entity of the generated invariant procedure in order to construct a
 289         proper entity chain.
 290
 291 2018-01-11  Piotr Trojanek  <trojanek@adacore.com>
 292
 293         * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
 294         comment.

 298         * einfo.ads, einfo.adb (Activation_Record_Component,
 299         Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
 300         Allow E_Discriminant.
 301
 302 2018-01-10  Eric Botcazou  <ebotcazou@adacore.com>
 303
 304         * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
 305         for atomic access once the component size is taken into account and
 306         also do it if the component type is Atomic or Volatile_Full_Access.
 307
 308 2018-01-04  Eric Botcazou  <ebotcazou@adacore.com>
 309
 310         * gnatvsn.ads: Bump copyright year.

 329
 330         * gcc-interface/utils.c (gnat_types_compatible_p): Handle
