   2
   3         * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
   4         Update description of restriction SPARK_05 with SPARK 2014.
   5         * gnat_rm.texi: Regenerate.
   6
   7 2018-01-11  Vasiliy Fofanov  <fofanov@adacore.com>
   8
   9         * doc/gnat_ugn/gnat_utility_programs.rst: Fix layout.
  10
  11 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
  12
  13         * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
  14         sem_res.adb, sem_util.adb: Minor reformatting.
  15
  16 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
  17
  18         * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
  19         has a delayed aspect which must be processed at the point the type is
  20         frozen. This mimics what is done when the predicate is provided by a
  21         source aspect.
  22
  23 2018-01-11  Doug Rupp  <rupp@adacore.com>
  24
  25         * init.c (vxworks): Add macro checks for __aarch64__.
  26
  27 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
  28
  29         * exp_util.adb (Add_Failure_Expression): New routine.
  30         (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
  31         * sem_util.adb (Is_Current_Instance): Code cleanup.
  32
  33 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
  34
  35         * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
  36         Default_Sec_Stack_Size.
  37         * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
  38         limit check so that the integer index does not overflow. Check the
  39         dynamic stack allocation does not cause the secondary stack pointer to
  40         overflow.
  41         (SS_Info): Align colons.
  42         (SS_Init): Cover the case when bootstraping with an old compiler that
  43         does not set Default_SS_Size.
  44
  45 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
  46
  47         * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
  48         legality of an inherited operation that may require overriding, ignore
  49         primitive_wrappers that correspond to explicit operations that override
  50         an interface primitive.
  51         * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
  52         operation to which the class-wide expression applies is a protected op.
  53         with a primitive_wrapper, verify that the updated inherited expression
  54         does not contain an internal call to a protected function.  This
  55         completes the implementation of AI12-0166.
  56
  57 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
  58
  59         * ali.adb: Document the remaining letters available for ALI lines.
  60         (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
  61         * ali.ads: Update type With_Record. Field
  62         Implicit_With_From_Instantiation is no longer in use. Add field
  63         Implicit_With.
  64         * csinfo.adb (CSinfo): Remove the setup for attribute
  65         Implicit_With_From_Instantiation.
  66         * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
  67         either implicitly or explicitly withed.
  68         (Is_Implicit_With_Clause): New routine.
  69         (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
  70         confusion with the with clause attribute by the same name.
  71         (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
  72         * rtsfind.adb (Maybe_Add_With): Code cleanup.
  73         * sem_ch8.adb (Present_System_Aux): Code cleanup.
  74         * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
  75         for a parent unit.
  76         (Implicit_With_On_Parent): Mark the with clause as generated for a
  77         parent unit.
  78         * sem_ch12.adb (Inherit_Context): With clauses inherited by an
  79         instantiation are no longer marked as Implicit_With_From_Instantiation
  80         because they are already marked as implicit.
  81         * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
  82         which marks implicit with clauses as related to an instantiation.
  83         * sinfo.adb (Implicit_With_From_Instantiation): Removed.
  84         (Parent_With): New routine.
  85         (Set_Implicit_With_From_Instantiation): Removed.
  86         (Set_Parent_With): New routine.
  87         * sinfo.ads: Update the documentation of attribute Implicit_With.
  88         Remove attribute Implicit_With_From_Instantiation along with
  89         occurrences in nodes.  Add attribute Parent_With along with occurrences
  90         in nodes.
  91         (Implicit_With_From_Instantiation): Removed along with pragma Inline.
  92         (Parent_With): New routine along with pragma Inline.
  93         (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
  94         (Set_Parent_With): New routine along with pragma Inline.
  95
  96 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
  97
  98         * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
  99         entity when the enclosing construct is a body.
 100
 101 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
 102
 103         * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
 104         Secondary_Stack_Size handling as a pragma is now generated for the
 105         corresponding aspect instead of an attribute.  Pragma expression is
 106         relocated instead of evaluated. Discriminant of the corresponding
 107         record type is referenced rather than the type discriminant.
 108         (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
 109         Secondary_Stack_Size rep item checks to only look for the pragma rep.
 110         * sem_ch13.adb (Analyze_One_Aspect): Transform
 111         Aspect_Secondary_Stack_Size into a pragma instead of an attribute
 112         because the attribute does not have visibility on a task type's
 113         discriminants when the type's definition is expanded.
 114         (Analyze_Attribute_Definition_Clause): Remove handling of
 115         Attribute_Secondary_Stack_Size.
 116         * snames.adb-tmpl, snames.ads-tmpl: Remove
 117         Attribute_Secondary_Stack_Size, no longer used.
 118
 119 2018-01-11  Justin Squirek  <squirek@adacore.com>
 120
 121         * sem_ch8.adb: Minor comment fix.
 122
 123 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 124
 125         * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
 126         individual action because the action may denote a complex expression,
 127         such as a case statement, which in turn may contain additional
 128         transient objects.
 129
 130 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
 131
 132         * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
 133         analysis on a copy of the expression with a copy of the index variable,
 134         because full expansion will rewrite construct into a loop with the
 135         original loop variable.
 136         * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
 137         expression is an iterated component association. Full analysis takes
 138         place when construct is rewritten as a loop.
 139         (In_Place_Assign_OK, Safe_Component): An iterated_component_association
 140         is not safe for in-place assignment.
 141         * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
 142         entity with no homonym and no other entity in the scope.
 143
 144 2018-01-11  Justin Squirek  <squirek@adacore.com>
 145
 146         * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
 147         message to be printed on the pragma argument identifier.
 148
 149 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 150
 151         * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
 152         entity of the generated invariant procedure in order to construct a
 153         proper entity chain.
 154
 155 2018-01-11  Piotr Trojanek  <trojanek@adacore.com>
 156
 157         * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
 158         comment.
 159
 160 2018-01-11  Arnaud Charlet  <charlet@adacore.com>
 161
 162         * einfo.ads, einfo.adb (Activation_Record_Component,
 163         Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
 164         Allow E_Discriminant.
 165
 166 2018-01-10  Eric Botcazou  <ebotcazou@adacore.com>
 167
 168         * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
 169         for atomic access once the component size is taken into account and
 170         also do it if the component type is Atomic or Volatile_Full_Access.
 171
 172 2018-01-04  Eric Botcazou  <ebotcazou@adacore.com>
 173
 174         * gnatvsn.ads: Bump copyright year.
 175
 176 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 177             Alan Hayward  <alan.hayward@arm.com>
 178             David Sherwood  <david.sherwood@arm.com>
 179
 180         * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_BITSIZE
 181         as polynomial.
 182
 183 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 184             Alan Hayward  <alan.hayward@arm.com>
 185             David Sherwood  <david.sherwood@arm.com>
 186
 187         * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_PRECISION
 188         as polynomial.
 189
 190 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 191             Alan Hayward  <alan.hayward@arm.com>
 192             David Sherwood  <david.sherwood@arm.com>
 193
 194         * gcc-interface/utils.c (gnat_types_compatible_p): Handle
 195         polynomial TYPE_VECTOR_SUBPARTS.
 196
 197 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 198             Alan Hayward  <alan.hayward@arm.com>
 199             David Sherwood  <david.sherwood@arm.com>
 200
 201         * gcc-interface/misc.c (enumerate_modes): Handle polynomial
 202         GET_MODE_NUNITS.
 203
