  38         * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
  39         formsl type corresponding to the actual fixed point type is private,
  40         because in this case there can be no suspicious arithmetic operations
  41         in the generic unless they reference a formal subprogram.  Clarify
  42         warning.
  43
  44 2018-01-11  Javier Miranda  <miranda@adacore.com>
  45
  46         * exp_util.adb (Remove_Side_Effects): No action done for functions
  47         returning class-wide types since it requires generating code using
  48         'reference and the CCG target has no secondary stack.
  49         * gnat1drv.adb: Disable building static dispatch tables when generating
  50         C code.
  51
  52 2018-01-11  Piotr Trojanek  <trojanek@adacore.com>

  69
  70         * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
  71         if it contains at least one component declaration employing a function
  72         call returning on the secondary stack.
  73
  74 2018-01-11  Yannick Moy  <moy@adacore.com>
  75

  88
  89 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
  90
  91         * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
  92         has a delayed aspect which must be processed at the point the type is
  93         frozen. This mimics what is done when the predicate is provided by a
  94         source aspect.
  95
  96 2018-01-11  Doug Rupp  <rupp@adacore.com>
  97
  98         * init.c (vxworks): Add macro checks for __aarch64__.
  99
 100 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 101
 102         * exp_util.adb (Add_Failure_Expression): New routine.
 103         (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
 104         * sem_util.adb (Is_Current_Instance): Code cleanup.
 105
 106 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
 107
 108         * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
 109         Default_Sec_Stack_Size.
 110         * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
 111         limit check so that the integer index does not overflow. Check the
 112         dynamic stack allocation does not cause the secondary stack pointer to
 113         overflow.
 114         (SS_Info): Align colons.
 115         (SS_Init): Cover the case when bootstraping with an old compiler that
 116         does not set Default_SS_Size.
 117
 118 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
 119
 120         * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
 121         legality of an inherited operation that may require overriding, ignore
 122         primitive_wrappers that correspond to explicit operations that override
 123         an interface primitive.
 124         * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
 125         operation to which the class-wide expression applies is a protected op.
 126         with a primitive_wrapper, verify that the updated inherited expression
 127         does not contain an internal call to a protected function.  This
 128         completes the implementation of AI12-0166.
 129
 130 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 131
 132         * ali.adb: Document the remaining letters available for ALI lines.
 133         (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
 134         * ali.ads: Update type With_Record. Field
 135         Implicit_With_From_Instantiation is no longer in use. Add field
 136         Implicit_With.
 137         * csinfo.adb (CSinfo): Remove the setup for attribute
 138         Implicit_With_From_Instantiation.
 139         * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
 140         either implicitly or explicitly withed.
 141         (Is_Implicit_With_Clause): New routine.
 142         (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
 143         confusion with the with clause attribute by the same name.
 144         (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
 145         * rtsfind.adb (Maybe_Add_With): Code cleanup.
 146         * sem_ch8.adb (Present_System_Aux): Code cleanup.
 147         * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
 148         for a parent unit.
 149         (Implicit_With_On_Parent): Mark the with clause as generated for a
 150         parent unit.
 151         * sem_ch12.adb (Inherit_Context): With clauses inherited by an
 152         instantiation are no longer marked as Implicit_With_From_Instantiation
 153         because they are already marked as implicit.
 154         * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
 155         which marks implicit with clauses as related to an instantiation.
 156         * sinfo.adb (Implicit_With_From_Instantiation): Removed.
 157         (Parent_With): New routine.
 158         (Set_Implicit_With_From_Instantiation): Removed.
 159         (Set_Parent_With): New routine.
 160         * sinfo.ads: Update the documentation of attribute Implicit_With.
 161         Remove attribute Implicit_With_From_Instantiation along with
 162         occurrences in nodes.  Add attribute Parent_With along with occurrences
 163         in nodes.
 164         (Implicit_With_From_Instantiation): Removed along with pragma Inline.
 165         (Parent_With): New routine along with pragma Inline.
 166         (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
 167         (Set_Parent_With): New routine along with pragma Inline.
 168
 169 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 170
 171         * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
 172         entity when the enclosing construct is a body.
 173
 174 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
 175
 176         * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
 177         Secondary_Stack_Size handling as a pragma is now generated for the
 178         corresponding aspect instead of an attribute.  Pragma expression is
 179         relocated instead of evaluated. Discriminant of the corresponding
 180         record type is referenced rather than the type discriminant.
 181         (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
 182         Secondary_Stack_Size rep item checks to only look for the pragma rep.
 183         * sem_ch13.adb (Analyze_One_Aspect): Transform
 184         Aspect_Secondary_Stack_Size into a pragma instead of an attribute
 185         because the attribute does not have visibility on a task type's
 186         discriminants when the type's definition is expanded.
 187         (Analyze_Attribute_Definition_Clause): Remove handling of
 188         Attribute_Secondary_Stack_Size.
 189         * snames.adb-tmpl, snames.ads-tmpl: Remove
 190         Attribute_Secondary_Stack_Size, no longer used.
 191
 192 2018-01-11  Justin Squirek  <squirek@adacore.com>
 193
 194         * sem_ch8.adb: Minor comment fix.
 195
 196 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 197
 198         * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
 199         individual action because the action may denote a complex expression,
 200         such as a case statement, which in turn may contain additional
 201         transient objects.
 202
 203 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
 204
 205         * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
 206         analysis on a copy of the expression with a copy of the index variable,
 207         because full expansion will rewrite construct into a loop with the
 208         original loop variable.
 209         * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
 210         expression is an iterated component association. Full analysis takes
 211         place when construct is rewritten as a loop.
 212         (In_Place_Assign_OK, Safe_Component): An iterated_component_association
 213         is not safe for in-place assignment.
 214         * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
 215         entity with no homonym and no other entity in the scope.
 216
 217 2018-01-11  Justin Squirek  <squirek@adacore.com>
 218
 219         * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
 220         message to be printed on the pragma argument identifier.
 221
 222 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 223
 224         * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
 225         entity of the generated invariant procedure in order to construct a
 226         proper entity chain.
 227
 228 2018-01-11  Piotr Trojanek  <trojanek@adacore.com>
 229
 230         * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
 231         comment.
 232
 233 2018-01-11  Arnaud Charlet  <charlet@adacore.com>
 234
 235         * einfo.ads, einfo.adb (Activation_Record_Component,
 236         Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
 237         Allow E_Discriminant.
 238
 239 2018-01-10  Eric Botcazou  <ebotcazou@adacore.com>
 240
 241         * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
 242         for atomic access once the component size is taken into account and
 243         also do it if the component type is Atomic or Volatile_Full_Access.
 244
 245 2018-01-04  Eric Botcazou  <ebotcazou@adacore.com>
 246
 247         * gnatvsn.ads: Bump copyright year.
 248
 249 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 250             Alan Hayward  <alan.hayward@arm.com>
 251             David Sherwood  <david.sherwood@arm.com>
 252
 253         * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_BITSIZE
 254         as polynomial.

 260         * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_PRECISION
 261         as polynomial.
 262
 263 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 264             Alan Hayward  <alan.hayward@arm.com>
 265             David Sherwood  <david.sherwood@arm.com>
 266
 267         * gcc-interface/utils.c (gnat_types_compatible_p): Handle
 268         polynomial TYPE_VECTOR_SUBPARTS.
 269
 270 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 271             Alan Hayward  <alan.hayward@arm.com>
