   7
   8         * sem_ch6.adb (Freeze_Expr_Types): If an access value is the
   9         controlling argument of a dispatching call. freeze the corresponding
  10         designated type.
  11
  12 2018-01-11  Ben Brosgol  <brosgol@adacore.com>
  13

  21
  22 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
  23
  24         * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
  25         formsl type corresponding to the actual fixed point type is private,
  26         because in this case there can be no suspicious arithmetic operations
  27         in the generic unless they reference a formal subprogram.  Clarify
  28         warning.
  29
  30 2018-01-11  Javier Miranda  <miranda@adacore.com>
  31
  32         * exp_util.adb (Remove_Side_Effects): No action done for functions
  33         returning class-wide types since it requires generating code using
  34         'reference and the CCG target has no secondary stack.
  35         * gnat1drv.adb: Disable building static dispatch tables when generating
  36         C code.
  37
  38 2018-01-11  Piotr Trojanek  <trojanek@adacore.com>

  53
  54 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
  55
  56         * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
  57         if it contains at least one component declaration employing a function
  58         call returning on the secondary stack.
  59
  60 2018-01-11  Yannick Moy  <moy@adacore.com>
  61
  62         * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
  63         Update description of restriction SPARK_05 with SPARK 2014.
  64         * gnat_rm.texi: Regenerate.
  65

  68         * doc/gnat_ugn/gnat_utility_programs.rst: Fix layout.
  69
  70 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
  71
  72         * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
  73         sem_res.adb, sem_util.adb: Minor reformatting.
  74
  75 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
  76
  77         * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
  78         has a delayed aspect which must be processed at the point the type is
  79         frozen. This mimics what is done when the predicate is provided by a
  80         source aspect.
  81
  82 2018-01-11  Doug Rupp  <rupp@adacore.com>
  83
  84         * init.c (vxworks): Add macro checks for __aarch64__.
  85
  86 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
  87
  88         * exp_util.adb (Add_Failure_Expression): New routine.
  89         (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
  90         * sem_util.adb (Is_Current_Instance): Code cleanup.
  91
  92 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
  93
  94         * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
  95         Default_Sec_Stack_Size.
  96         * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
  97         limit check so that the integer index does not overflow. Check the
  98         dynamic stack allocation does not cause the secondary stack pointer to
  99         overflow.
 100         (SS_Info): Align colons.
 101         (SS_Init): Cover the case when bootstraping with an old compiler that
 102         does not set Default_SS_Size.
 103
 104 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
 105
 106         * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
 107         legality of an inherited operation that may require overriding, ignore
 108         primitive_wrappers that correspond to explicit operations that override
 109         an interface primitive.
 110         * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
 111         operation to which the class-wide expression applies is a protected op.
 112         with a primitive_wrapper, verify that the updated inherited expression
 113         does not contain an internal call to a protected function.  This
 114         completes the implementation of AI12-0166.
 115
 116 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 117
 118         * ali.adb: Document the remaining letters available for ALI lines.
 119         (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
 120         * ali.ads: Update type With_Record. Field
 121         Implicit_With_From_Instantiation is no longer in use. Add field
 122         Implicit_With.
 123         * csinfo.adb (CSinfo): Remove the setup for attribute
 124         Implicit_With_From_Instantiation.
 125         * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
 126         either implicitly or explicitly withed.
 127         (Is_Implicit_With_Clause): New routine.
 128         (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
 129         confusion with the with clause attribute by the same name.
 130         (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
 131         * rtsfind.adb (Maybe_Add_With): Code cleanup.
 132         * sem_ch8.adb (Present_System_Aux): Code cleanup.
 133         * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
 134         for a parent unit.
 135         (Implicit_With_On_Parent): Mark the with clause as generated for a
 136         parent unit.
 137         * sem_ch12.adb (Inherit_Context): With clauses inherited by an
 138         instantiation are no longer marked as Implicit_With_From_Instantiation
 139         because they are already marked as implicit.
 140         * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
 141         which marks implicit with clauses as related to an instantiation.
 142         * sinfo.adb (Implicit_With_From_Instantiation): Removed.
 143         (Parent_With): New routine.
 144         (Set_Implicit_With_From_Instantiation): Removed.
 145         (Set_Parent_With): New routine.
 146         * sinfo.ads: Update the documentation of attribute Implicit_With.
 147         Remove attribute Implicit_With_From_Instantiation along with
 148         occurrences in nodes.  Add attribute Parent_With along with occurrences
 149         in nodes.
 150         (Implicit_With_From_Instantiation): Removed along with pragma Inline.
 151         (Parent_With): New routine along with pragma Inline.
 152         (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
 153         (Set_Parent_With): New routine along with pragma Inline.
 154
 155 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 156
 157         * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
 158         entity when the enclosing construct is a body.
 159
 160 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
 161
 162         * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
 163         Secondary_Stack_Size handling as a pragma is now generated for the
 164         corresponding aspect instead of an attribute.  Pragma expression is
 165         relocated instead of evaluated. Discriminant of the corresponding
 166         record type is referenced rather than the type discriminant.
 167         (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
 168         Secondary_Stack_Size rep item checks to only look for the pragma rep.
 169         * sem_ch13.adb (Analyze_One_Aspect): Transform
 170         Aspect_Secondary_Stack_Size into a pragma instead of an attribute
 171         because the attribute does not have visibility on a task type's
 172         discriminants when the type's definition is expanded.
 173         (Analyze_Attribute_Definition_Clause): Remove handling of
 174         Attribute_Secondary_Stack_Size.
 175         * snames.adb-tmpl, snames.ads-tmpl: Remove
 176         Attribute_Secondary_Stack_Size, no longer used.
 177
 178 2018-01-11  Justin Squirek  <squirek@adacore.com>
 179
 180         * sem_ch8.adb: Minor comment fix.
 181
 182 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 183
 184         * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
 185         individual action because the action may denote a complex expression,
 186         such as a case statement, which in turn may contain additional
 187         transient objects.
 188
 189 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
 190
 191         * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
 192         analysis on a copy of the expression with a copy of the index variable,
 193         because full expansion will rewrite construct into a loop with the
 194         original loop variable.
 195         * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
 196         expression is an iterated component association. Full analysis takes
 197         place when construct is rewritten as a loop.
 198         (In_Place_Assign_OK, Safe_Component): An iterated_component_association
 199         is not safe for in-place assignment.
 200         * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
 201         entity with no homonym and no other entity in the scope.
 202
 203 2018-01-11  Justin Squirek  <squirek@adacore.com>
 204
 205         * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
 206         message to be printed on the pragma argument identifier.
 207
 208 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 209
 210         * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
 211         entity of the generated invariant procedure in order to construct a
 212         proper entity chain.
 213
 214 2018-01-11  Piotr Trojanek  <trojanek@adacore.com>
 215
 216         * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
 217         comment.
 218
 219 2018-01-11  Arnaud Charlet  <charlet@adacore.com>
 220
 221         * einfo.ads, einfo.adb (Activation_Record_Component,
 222         Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
 223         Allow E_Discriminant.
 224
 225 2018-01-10  Eric Botcazou  <ebotcazou@adacore.com>
 226
 227         * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
 228         for atomic access once the component size is taken into account and
 229         also do it if the component type is Atomic or Volatile_Full_Access.
 230
 231 2018-01-04  Eric Botcazou  <ebotcazou@adacore.com>
 232
 233         * gnatvsn.ads: Bump copyright year.
 234
 235 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 236             Alan Hayward  <alan.hayward@arm.com>
 237             David Sherwood  <david.sherwood@arm.com>
 238
 239         * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_BITSIZE
 240         as polynomial.
 241
 242 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>

 244             David Sherwood  <david.sherwood@arm.com>
 245
 246         * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_PRECISION
 247         as polynomial.
 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/utils.c (gnat_types_compatible_p): Handle
 254         polynomial TYPE_VECTOR_SUBPARTS.
 255
 256 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 257             Alan Hayward  <alan.hayward@arm.com>

 259
 260         * gcc-interface/misc.c (enumerate_modes): Handle polynomial
 261         GET_MODE_NUNITS.
