  43
  44         * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
  45         formsl type corresponding to the actual fixed point type is private,
  46         because in this case there can be no suspicious arithmetic operations
  47         in the generic unless they reference a formal subprogram.  Clarify
  48         warning.
  49
  50 2018-01-11  Javier Miranda  <miranda@adacore.com>
  51
  52         * exp_util.adb (Remove_Side_Effects): No action done for functions
  53         returning class-wide types since it requires generating code using
  54         'reference and the CCG target has no secondary stack.
  55         * gnat1drv.adb: Disable building static dispatch tables when generating
  56         C code.
  57
  58 2018-01-11  Piotr Trojanek  <trojanek@adacore.com>

  76         * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
  77         if it contains at least one component declaration employing a function
  78         call returning on the secondary stack.
  79
  80 2018-01-11  Yannick Moy  <moy@adacore.com>

  94
  95 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
  96
  97         * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
  98         has a delayed aspect which must be processed at the point the type is
  99         frozen. This mimics what is done when the predicate is provided by a
 100         source aspect.
 101
 102 2018-01-11  Doug Rupp  <rupp@adacore.com>
 103
 104         * init.c (vxworks): Add macro checks for __aarch64__.
 105
 106 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 107
 108         * exp_util.adb (Add_Failure_Expression): New routine.
 109         (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
 110         * sem_util.adb (Is_Current_Instance): Code cleanup.
 111
 112 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
 113
 114         * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
 115         Default_Sec_Stack_Size.
 116         * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
 117         limit check so that the integer index does not overflow. Check the
 118         dynamic stack allocation does not cause the secondary stack pointer to
 119         overflow.
 120         (SS_Info): Align colons.
 121         (SS_Init): Cover the case when bootstraping with an old compiler that
 122         does not set Default_SS_Size.
 123
 124 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
 125
 126         * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
 127         legality of an inherited operation that may require overriding, ignore
 128         primitive_wrappers that correspond to explicit operations that override
 129         an interface primitive.
 130         * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
 131         operation to which the class-wide expression applies is a protected op.
 132         with a primitive_wrapper, verify that the updated inherited expression
 133         does not contain an internal call to a protected function.  This
 134         completes the implementation of AI12-0166.
 135
 136 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 137
 138         * ali.adb: Document the remaining letters available for ALI lines.
 139         (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
 140         * ali.ads: Update type With_Record. Field
 141         Implicit_With_From_Instantiation is no longer in use. Add field
 142         Implicit_With.
 143         * csinfo.adb (CSinfo): Remove the setup for attribute
 144         Implicit_With_From_Instantiation.
 145         * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
 146         either implicitly or explicitly withed.
 147         (Is_Implicit_With_Clause): New routine.
 148         (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
 149         confusion with the with clause attribute by the same name.
 150         (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
 151         * rtsfind.adb (Maybe_Add_With): Code cleanup.
 152         * sem_ch8.adb (Present_System_Aux): Code cleanup.
 153         * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
 154         for a parent unit.
 155         (Implicit_With_On_Parent): Mark the with clause as generated for a
 156         parent unit.
 157         * sem_ch12.adb (Inherit_Context): With clauses inherited by an
 158         instantiation are no longer marked as Implicit_With_From_Instantiation
 159         because they are already marked as implicit.
 160         * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
 161         which marks implicit with clauses as related to an instantiation.
 162         * sinfo.adb (Implicit_With_From_Instantiation): Removed.
 163         (Parent_With): New routine.
 164         (Set_Implicit_With_From_Instantiation): Removed.
 165         (Set_Parent_With): New routine.
 166         * sinfo.ads: Update the documentation of attribute Implicit_With.
 167         Remove attribute Implicit_With_From_Instantiation along with
 168         occurrences in nodes.  Add attribute Parent_With along with occurrences
 169         in nodes.
 170         (Implicit_With_From_Instantiation): Removed along with pragma Inline.
 171         (Parent_With): New routine along with pragma Inline.
 172         (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
 173         (Set_Parent_With): New routine along with pragma Inline.
 174
 175 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 176
 177         * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
 178         entity when the enclosing construct is a body.
 179
 180 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
 181
 182         * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
 183         Secondary_Stack_Size handling as a pragma is now generated for the
 184         corresponding aspect instead of an attribute.  Pragma expression is
 185         relocated instead of evaluated. Discriminant of the corresponding
 186         record type is referenced rather than the type discriminant.
 187         (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
 188         Secondary_Stack_Size rep item checks to only look for the pragma rep.
 189         * sem_ch13.adb (Analyze_One_Aspect): Transform
 190         Aspect_Secondary_Stack_Size into a pragma instead of an attribute
 191         because the attribute does not have visibility on a task type's
 192         discriminants when the type's definition is expanded.
 193         (Analyze_Attribute_Definition_Clause): Remove handling of
 194         Attribute_Secondary_Stack_Size.
 195         * snames.adb-tmpl, snames.ads-tmpl: Remove
 196         Attribute_Secondary_Stack_Size, no longer used.
 197
 198 2018-01-11  Justin Squirek  <squirek@adacore.com>
 199
 200         * sem_ch8.adb: Minor comment fix.
 201
 202 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 203
 204         * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
 205         individual action because the action may denote a complex expression,
 206         such as a case statement, which in turn may contain additional
 207         transient objects.
 208
 209 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
 210
 211         * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
 212         analysis on a copy of the expression with a copy of the index variable,
 213         because full expansion will rewrite construct into a loop with the
 214         original loop variable.
 215         * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
 216         expression is an iterated component association. Full analysis takes
 217         place when construct is rewritten as a loop.
 218         (In_Place_Assign_OK, Safe_Component): An iterated_component_association
 219         is not safe for in-place assignment.
 220         * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
 221         entity with no homonym and no other entity in the scope.
 222
 223 2018-01-11  Justin Squirek  <squirek@adacore.com>
 224
 225         * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
 226         message to be printed on the pragma argument identifier.
 227
 228 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 229
 230         * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
 231         entity of the generated invariant procedure in order to construct a
 232         proper entity chain.
 233
 234 2018-01-11  Piotr Trojanek  <trojanek@adacore.com>
 235
 236         * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
 237         comment.
 238
 239 2018-01-11  Arnaud Charlet  <charlet@adacore.com>
 240
 241         * einfo.ads, einfo.adb (Activation_Record_Component,
 242         Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
 243         Allow E_Discriminant.
 244
 245 2018-01-10  Eric Botcazou  <ebotcazou@adacore.com>
 246
 247         * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
 248         for atomic access once the component size is taken into account and
 249         also do it if the component type is Atomic or Volatile_Full_Access.
 250
 251 2018-01-04  Eric Botcazou  <ebotcazou@adacore.com>
 252
 253         * gnatvsn.ads: Bump copyright year.
 254
 255 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 256             Alan Hayward  <alan.hayward@arm.com>
 257             David Sherwood  <david.sherwood@arm.com>
 258
 259         * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_BITSIZE
 260         as polynomial.

 266         * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_PRECISION
 267         as polynomial.
 268
 269 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 270             Alan Hayward  <alan.hayward@arm.com>
 271             David Sherwood  <david.sherwood@arm.com>
 272
 273         * gcc-interface/utils.c (gnat_types_compatible_p): Handle
 274         polynomial TYPE_VECTOR_SUBPARTS.
 275
 276 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 277             Alan Hayward  <alan.hayward@arm.com>
