  12
  13         * sem_ch6.adb (Freeze_Expr_Types): If an access value is the
  14         controlling argument of a dispatching call. freeze the corresponding
  15         designated type.
  16

  27 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
  28
  29         * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
  30         formsl type corresponding to the actual fixed point type is private,
  31         because in this case there can be no suspicious arithmetic operations
  32         in the generic unless they reference a formal subprogram.  Clarify
  33         warning.
  34
  35 2018-01-11  Javier Miranda  <miranda@adacore.com>
  36
  37         * exp_util.adb (Remove_Side_Effects): No action done for functions
  38         returning class-wide types since it requires generating code using
  39         'reference and the CCG target has no secondary stack.
  40         * gnat1drv.adb: Disable building static dispatch tables when generating
  41         C code.
  42
  43 2018-01-11  Piotr Trojanek  <trojanek@adacore.com>

  58
  59 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
  60
  61         * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
  62         if it contains at least one component declaration employing a function
  63         call returning on the secondary stack.
  64
  65 2018-01-11  Yannick Moy  <moy@adacore.com>
  66
  67         * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:

  74
  75 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
  76
  77         * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
  78         sem_res.adb, sem_util.adb: Minor reformatting.
  79
  80 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
  81
  82         * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
  83         has a delayed aspect which must be processed at the point the type is
  84         frozen. This mimics what is done when the predicate is provided by a
  85         source aspect.
  86
  87 2018-01-11  Doug Rupp  <rupp@adacore.com>
  88
  89         * init.c (vxworks): Add macro checks for __aarch64__.
  90
  91 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
  92
  93         * exp_util.adb (Add_Failure_Expression): New routine.
  94         (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
  95         * sem_util.adb (Is_Current_Instance): Code cleanup.
  96
  97 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
  98
  99         * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
 100         Default_Sec_Stack_Size.
 101         * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
 102         limit check so that the integer index does not overflow. Check the
 103         dynamic stack allocation does not cause the secondary stack pointer to
 104         overflow.
 105         (SS_Info): Align colons.
 106         (SS_Init): Cover the case when bootstraping with an old compiler that
 107         does not set Default_SS_Size.
 108
 109 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
 110
 111         * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
 112         legality of an inherited operation that may require overriding, ignore
 113         primitive_wrappers that correspond to explicit operations that override
 114         an interface primitive.
 115         * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
 116         operation to which the class-wide expression applies is a protected op.
 117         with a primitive_wrapper, verify that the updated inherited expression
 118         does not contain an internal call to a protected function.  This
 119         completes the implementation of AI12-0166.
 120
 121 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 122
 123         * ali.adb: Document the remaining letters available for ALI lines.
 124         (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
 125         * ali.ads: Update type With_Record. Field
 126         Implicit_With_From_Instantiation is no longer in use. Add field
 127         Implicit_With.
 128         * csinfo.adb (CSinfo): Remove the setup for attribute
 129         Implicit_With_From_Instantiation.
 130         * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
 131         either implicitly or explicitly withed.
 132         (Is_Implicit_With_Clause): New routine.
 133         (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
 134         confusion with the with clause attribute by the same name.
 135         (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
 136         * rtsfind.adb (Maybe_Add_With): Code cleanup.
 137         * sem_ch8.adb (Present_System_Aux): Code cleanup.
 138         * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
 139         for a parent unit.
 140         (Implicit_With_On_Parent): Mark the with clause as generated for a
 141         parent unit.
 142         * sem_ch12.adb (Inherit_Context): With clauses inherited by an
 143         instantiation are no longer marked as Implicit_With_From_Instantiation
 144         because they are already marked as implicit.
 145         * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
 146         which marks implicit with clauses as related to an instantiation.
 147         * sinfo.adb (Implicit_With_From_Instantiation): Removed.
 148         (Parent_With): New routine.
 149         (Set_Implicit_With_From_Instantiation): Removed.
 150         (Set_Parent_With): New routine.
 151         * sinfo.ads: Update the documentation of attribute Implicit_With.
 152         Remove attribute Implicit_With_From_Instantiation along with
 153         occurrences in nodes.  Add attribute Parent_With along with occurrences
 154         in nodes.
 155         (Implicit_With_From_Instantiation): Removed along with pragma Inline.
 156         (Parent_With): New routine along with pragma Inline.
 157         (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
 158         (Set_Parent_With): New routine along with pragma Inline.
 159
 160 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 161
 162         * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
 163         entity when the enclosing construct is a body.
 164
 165 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
 166
 167         * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
 168         Secondary_Stack_Size handling as a pragma is now generated for the
 169         corresponding aspect instead of an attribute.  Pragma expression is
 170         relocated instead of evaluated. Discriminant of the corresponding
 171         record type is referenced rather than the type discriminant.
 172         (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
 173         Secondary_Stack_Size rep item checks to only look for the pragma rep.
 174         * sem_ch13.adb (Analyze_One_Aspect): Transform
 175         Aspect_Secondary_Stack_Size into a pragma instead of an attribute
 176         because the attribute does not have visibility on a task type's
 177         discriminants when the type's definition is expanded.
 178         (Analyze_Attribute_Definition_Clause): Remove handling of
 179         Attribute_Secondary_Stack_Size.
 180         * snames.adb-tmpl, snames.ads-tmpl: Remove
 181         Attribute_Secondary_Stack_Size, no longer used.
 182
 183 2018-01-11  Justin Squirek  <squirek@adacore.com>
 184
 185         * sem_ch8.adb: Minor comment fix.
 186
 187 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 188
 189         * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
 190         individual action because the action may denote a complex expression,
 191         such as a case statement, which in turn may contain additional
 192         transient objects.
 193
 194 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
 195
 196         * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
 197         analysis on a copy of the expression with a copy of the index variable,
 198         because full expansion will rewrite construct into a loop with the
 199         original loop variable.
 200         * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
 201         expression is an iterated component association. Full analysis takes
 202         place when construct is rewritten as a loop.
 203         (In_Place_Assign_OK, Safe_Component): An iterated_component_association
 204         is not safe for in-place assignment.
 205         * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
 206         entity with no homonym and no other entity in the scope.
 207
 208 2018-01-11  Justin Squirek  <squirek@adacore.com>
 209
 210         * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
 211         message to be printed on the pragma argument identifier.
 212
 213 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 214
 215         * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
 216         entity of the generated invariant procedure in order to construct a
 217         proper entity chain.
 218
 219 2018-01-11  Piotr Trojanek  <trojanek@adacore.com>
 220
 221         * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
 222         comment.
 223
 224 2018-01-11  Arnaud Charlet  <charlet@adacore.com>
 225
 226         * einfo.ads, einfo.adb (Activation_Record_Component,
 227         Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
 228         Allow E_Discriminant.
 229
 230 2018-01-10  Eric Botcazou  <ebotcazou@adacore.com>
 231
 232         * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
 233         for atomic access once the component size is taken into account and
 234         also do it if the component type is Atomic or Volatile_Full_Access.
 235
 236 2018-01-04  Eric Botcazou  <ebotcazou@adacore.com>
 237
 238         * gnatvsn.ads: Bump copyright year.
 239
 240 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 241             Alan Hayward  <alan.hayward@arm.com>
 242             David Sherwood  <david.sherwood@arm.com>
 243
 244         * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_BITSIZE
 245         as polynomial.
 246

 249             David Sherwood  <david.sherwood@arm.com>
 250
 251         * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_PRECISION
 252         as polynomial.
 253
 254 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 255             Alan Hayward  <alan.hayward@arm.com>
 256             David Sherwood  <david.sherwood@arm.com>
 257
 258         * gcc-interface/utils.c (gnat_types_compatible_p): Handle
 259         polynomial TYPE_VECTOR_SUBPARTS.
 260
 261 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 262             Alan Hayward  <alan.hayward@arm.com>

 264
 265         * gcc-interface/misc.c (enumerate_modes): Handle polynomial
 266         GET_MODE_NUNITS.
