  32
  33         * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
  34         formsl type corresponding to the actual fixed point type is private,
  35         because in this case there can be no suspicious arithmetic operations
  36         in the generic unless they reference a formal subprogram.  Clarify
  37         warning.
  38
  39 2018-01-11  Javier Miranda  <miranda@adacore.com>
  40
  41         * exp_util.adb (Remove_Side_Effects): No action done for functions
  42         returning class-wide types since it requires generating code using
  43         'reference and the CCG target has no secondary stack.
  44         * gnat1drv.adb: Disable building static dispatch tables when generating
  45         C code.
  46
  47 2018-01-11  Piotr Trojanek  <trojanek@adacore.com>

  62
  63 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
  64
  65         * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
  66         if it contains at least one component declaration employing a function
  67         call returning on the secondary stack.
  68
  69 2018-01-11  Yannick Moy  <moy@adacore.com>
  70

  82         sem_res.adb, sem_util.adb: Minor reformatting.
  83
  84 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
  85
  86         * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
  87         has a delayed aspect which must be processed at the point the type is
  88         frozen. This mimics what is done when the predicate is provided by a
  89         source aspect.
  90
  91 2018-01-11  Doug Rupp  <rupp@adacore.com>
  92
  93         * init.c (vxworks): Add macro checks for __aarch64__.
  94
  95 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
  96
  97         * exp_util.adb (Add_Failure_Expression): New routine.
  98         (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
  99         * sem_util.adb (Is_Current_Instance): Code cleanup.
 100
 101 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
 102
 103         * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
 104         Default_Sec_Stack_Size.
 105         * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
 106         limit check so that the integer index does not overflow. Check the
 107         dynamic stack allocation does not cause the secondary stack pointer to
 108         overflow.
 109         (SS_Info): Align colons.
 110         (SS_Init): Cover the case when bootstraping with an old compiler that
 111         does not set Default_SS_Size.
 112
 113 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
 114
 115         * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
 116         legality of an inherited operation that may require overriding, ignore
 117         primitive_wrappers that correspond to explicit operations that override
 118         an interface primitive.
 119         * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
 120         operation to which the class-wide expression applies is a protected op.
 121         with a primitive_wrapper, verify that the updated inherited expression
 122         does not contain an internal call to a protected function.  This
 123         completes the implementation of AI12-0166.
 124
 125 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 126
 127         * ali.adb: Document the remaining letters available for ALI lines.
 128         (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
 129         * ali.ads: Update type With_Record. Field
 130         Implicit_With_From_Instantiation is no longer in use. Add field
 131         Implicit_With.
 132         * csinfo.adb (CSinfo): Remove the setup for attribute
 133         Implicit_With_From_Instantiation.
 134         * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
 135         either implicitly or explicitly withed.
 136         (Is_Implicit_With_Clause): New routine.
 137         (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
 138         confusion with the with clause attribute by the same name.
 139         (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
 140         * rtsfind.adb (Maybe_Add_With): Code cleanup.
 141         * sem_ch8.adb (Present_System_Aux): Code cleanup.
 142         * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
 143         for a parent unit.
 144         (Implicit_With_On_Parent): Mark the with clause as generated for a
 145         parent unit.
 146         * sem_ch12.adb (Inherit_Context): With clauses inherited by an
 147         instantiation are no longer marked as Implicit_With_From_Instantiation
 148         because they are already marked as implicit.
 149         * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
 150         which marks implicit with clauses as related to an instantiation.
 151         * sinfo.adb (Implicit_With_From_Instantiation): Removed.
 152         (Parent_With): New routine.
 153         (Set_Implicit_With_From_Instantiation): Removed.
 154         (Set_Parent_With): New routine.
 155         * sinfo.ads: Update the documentation of attribute Implicit_With.
 156         Remove attribute Implicit_With_From_Instantiation along with
 157         occurrences in nodes.  Add attribute Parent_With along with occurrences
 158         in nodes.
 159         (Implicit_With_From_Instantiation): Removed along with pragma Inline.
 160         (Parent_With): New routine along with pragma Inline.
 161         (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
 162         (Set_Parent_With): New routine along with pragma Inline.
 163
 164 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 165
 166         * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
 167         entity when the enclosing construct is a body.
 168
 169 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
 170
 171         * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
 172         Secondary_Stack_Size handling as a pragma is now generated for the
 173         corresponding aspect instead of an attribute.  Pragma expression is
 174         relocated instead of evaluated. Discriminant of the corresponding
 175         record type is referenced rather than the type discriminant.
 176         (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
 177         Secondary_Stack_Size rep item checks to only look for the pragma rep.
 178         * sem_ch13.adb (Analyze_One_Aspect): Transform
 179         Aspect_Secondary_Stack_Size into a pragma instead of an attribute
 180         because the attribute does not have visibility on a task type's
 181         discriminants when the type's definition is expanded.
 182         (Analyze_Attribute_Definition_Clause): Remove handling of
 183         Attribute_Secondary_Stack_Size.
 184         * snames.adb-tmpl, snames.ads-tmpl: Remove
 185         Attribute_Secondary_Stack_Size, no longer used.
 186
 187 2018-01-11  Justin Squirek  <squirek@adacore.com>
 188
 189         * sem_ch8.adb: Minor comment fix.
 190
 191 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 192
 193         * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
 194         individual action because the action may denote a complex expression,
 195         such as a case statement, which in turn may contain additional
 196         transient objects.
 197
 198 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
 199
 200         * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
 201         analysis on a copy of the expression with a copy of the index variable,
 202         because full expansion will rewrite construct into a loop with the
 203         original loop variable.
 204         * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
 205         expression is an iterated component association. Full analysis takes
 206         place when construct is rewritten as a loop.
 207         (In_Place_Assign_OK, Safe_Component): An iterated_component_association
 208         is not safe for in-place assignment.
 209         * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
 210         entity with no homonym and no other entity in the scope.
 211
 212 2018-01-11  Justin Squirek  <squirek@adacore.com>
 213
 214         * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
 215         message to be printed on the pragma argument identifier.
 216
 217 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 218
 219         * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
 220         entity of the generated invariant procedure in order to construct a
 221         proper entity chain.
 222
 223 2018-01-11  Piotr Trojanek  <trojanek@adacore.com>
 224
 225         * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
 226         comment.
 227
 228 2018-01-11  Arnaud Charlet  <charlet@adacore.com>
 229
 230         * einfo.ads, einfo.adb (Activation_Record_Component,
 231         Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
 232         Allow E_Discriminant.
 233
 234 2018-01-10  Eric Botcazou  <ebotcazou@adacore.com>
 235
 236         * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
 237         for atomic access once the component size is taken into account and
 238         also do it if the component type is Atomic or Volatile_Full_Access.
 239
 240 2018-01-04  Eric Botcazou  <ebotcazou@adacore.com>
 241
 242         * gnatvsn.ads: Bump copyright year.
 243
 244 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 245             Alan Hayward  <alan.hayward@arm.com>
 246             David Sherwood  <david.sherwood@arm.com>
 247
 248         * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_BITSIZE
 249         as polynomial.
 250
 251 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>

 253             David Sherwood  <david.sherwood@arm.com>
 254
 255         * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_PRECISION
 256         as polynomial.
 257
 258 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 259             Alan Hayward  <alan.hayward@arm.com>
 260             David Sherwood  <david.sherwood@arm.com>
 261
 262         * gcc-interface/utils.c (gnat_types_compatible_p): Handle
 263         polynomial TYPE_VECTOR_SUBPARTS.
 264
 265 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 266             Alan Hayward  <alan.hayward@arm.com>
