   4
   5 2018-01-11  Ben Brosgol  <brosgol@adacore.com>
   6
   7         * doc/gnat_rm/implementation_defined_aspects.rst: Minor type/wording
   8         corrections.

  10
  11 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
  12
  13         * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
  14         formsl type corresponding to the actual fixed point type is private,
  15         because in this case there can be no suspicious arithmetic operations
  16         in the generic unless they reference a formal subprogram.  Clarify
  17         warning.
  18
  19 2018-01-11  Javier Miranda  <miranda@adacore.com>
  20
  21         * exp_util.adb (Remove_Side_Effects): No action done for functions
  22         returning class-wide types since it requires generating code using
  23         'reference and the CCG target has no secondary stack.
  24         * gnat1drv.adb: Disable building static dispatch tables when generating
  25         C code.
  26
  27 2018-01-11  Piotr Trojanek  <trojanek@adacore.com>
  28
  29         * libgnat/a-direio.ads, libgnat/a-sequio.ads, libgnat/a-ststio.ads,

  36
  37 2018-01-11  Bob Duff  <duff@adacore.com>
  38
  39         * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
  40         to match what the Libadalang-based version does.
  41         * doc/gnat_ugn/about_this_guide.rst: Update reference.
  42
  43 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
  44
  45         * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
  46         if it contains at least one component declaration employing a function
  47         call returning on the secondary stack.
  48
  49 2018-01-11  Yannick Moy  <moy@adacore.com>
  50
  51         * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
  52         Update description of restriction SPARK_05 with SPARK 2014.
  53         * gnat_rm.texi: Regenerate.
  54
  55 2018-01-11  Vasiliy Fofanov  <fofanov@adacore.com>
  56
  57         * doc/gnat_ugn/gnat_utility_programs.rst: Fix layout.
  58
  59 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
  60
  61         * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
  62         sem_res.adb, sem_util.adb: Minor reformatting.
  63
  64 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
  65
  66         * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
  67         has a delayed aspect which must be processed at the point the type is
  68         frozen. This mimics what is done when the predicate is provided by a
  69         source aspect.
  70
  71 2018-01-11  Doug Rupp  <rupp@adacore.com>
  72
  73         * init.c (vxworks): Add macro checks for __aarch64__.
  74
  75 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
  76
  77         * exp_util.adb (Add_Failure_Expression): New routine.
  78         (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
  79         * sem_util.adb (Is_Current_Instance): Code cleanup.
  80
  81 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
  82
  83         * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
  84         Default_Sec_Stack_Size.
  85         * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
  86         limit check so that the integer index does not overflow. Check the
  87         dynamic stack allocation does not cause the secondary stack pointer to
  88         overflow.
  89         (SS_Info): Align colons.
  90         (SS_Init): Cover the case when bootstraping with an old compiler that
  91         does not set Default_SS_Size.
  92
  93 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
  94
  95         * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
  96         legality of an inherited operation that may require overriding, ignore
  97         primitive_wrappers that correspond to explicit operations that override
  98         an interface primitive.
  99         * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
 100         operation to which the class-wide expression applies is a protected op.
 101         with a primitive_wrapper, verify that the updated inherited expression
 102         does not contain an internal call to a protected function.  This
 103         completes the implementation of AI12-0166.
 104
 105 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 106
 107         * ali.adb: Document the remaining letters available for ALI lines.
 108         (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
 109         * ali.ads: Update type With_Record. Field
 110         Implicit_With_From_Instantiation is no longer in use. Add field
 111         Implicit_With.
 112         * csinfo.adb (CSinfo): Remove the setup for attribute
 113         Implicit_With_From_Instantiation.
 114         * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
 115         either implicitly or explicitly withed.
 116         (Is_Implicit_With_Clause): New routine.
 117         (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
 118         confusion with the with clause attribute by the same name.
 119         (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
 120         * rtsfind.adb (Maybe_Add_With): Code cleanup.
 121         * sem_ch8.adb (Present_System_Aux): Code cleanup.
 122         * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
 123         for a parent unit.
 124         (Implicit_With_On_Parent): Mark the with clause as generated for a
 125         parent unit.
 126         * sem_ch12.adb (Inherit_Context): With clauses inherited by an
 127         instantiation are no longer marked as Implicit_With_From_Instantiation
 128         because they are already marked as implicit.
 129         * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
 130         which marks implicit with clauses as related to an instantiation.
 131         * sinfo.adb (Implicit_With_From_Instantiation): Removed.
 132         (Parent_With): New routine.
 133         (Set_Implicit_With_From_Instantiation): Removed.
 134         (Set_Parent_With): New routine.
 135         * sinfo.ads: Update the documentation of attribute Implicit_With.
 136         Remove attribute Implicit_With_From_Instantiation along with
 137         occurrences in nodes.  Add attribute Parent_With along with occurrences
 138         in nodes.
 139         (Implicit_With_From_Instantiation): Removed along with pragma Inline.
 140         (Parent_With): New routine along with pragma Inline.
 141         (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
 142         (Set_Parent_With): New routine along with pragma Inline.
 143
 144 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 145
 146         * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
 147         entity when the enclosing construct is a body.
 148
 149 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
 150
 151         * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
 152         Secondary_Stack_Size handling as a pragma is now generated for the
 153         corresponding aspect instead of an attribute.  Pragma expression is
 154         relocated instead of evaluated. Discriminant of the corresponding
 155         record type is referenced rather than the type discriminant.
 156         (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
 157         Secondary_Stack_Size rep item checks to only look for the pragma rep.
 158         * sem_ch13.adb (Analyze_One_Aspect): Transform
 159         Aspect_Secondary_Stack_Size into a pragma instead of an attribute
 160         because the attribute does not have visibility on a task type's
 161         discriminants when the type's definition is expanded.
 162         (Analyze_Attribute_Definition_Clause): Remove handling of
 163         Attribute_Secondary_Stack_Size.
 164         * snames.adb-tmpl, snames.ads-tmpl: Remove
 165         Attribute_Secondary_Stack_Size, no longer used.
 166
 167 2018-01-11  Justin Squirek  <squirek@adacore.com>
 168
 169         * sem_ch8.adb: Minor comment fix.
 170
 171 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 172
 173         * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
 174         individual action because the action may denote a complex expression,
 175         such as a case statement, which in turn may contain additional
 176         transient objects.
 177
 178 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
 179
 180         * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
 181         analysis on a copy of the expression with a copy of the index variable,
 182         because full expansion will rewrite construct into a loop with the
 183         original loop variable.
 184         * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
 185         expression is an iterated component association. Full analysis takes
 186         place when construct is rewritten as a loop.
 187         (In_Place_Assign_OK, Safe_Component): An iterated_component_association
 188         is not safe for in-place assignment.
 189         * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
 190         entity with no homonym and no other entity in the scope.
 191
 192 2018-01-11  Justin Squirek  <squirek@adacore.com>
 193
 194         * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
 195         message to be printed on the pragma argument identifier.
 196
 197 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 198
 199         * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
 200         entity of the generated invariant procedure in order to construct a
 201         proper entity chain.
 202
 203 2018-01-11  Piotr Trojanek  <trojanek@adacore.com>
 204
 205         * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
 206         comment.
 207
 208 2018-01-11  Arnaud Charlet  <charlet@adacore.com>
 209
 210         * einfo.ads, einfo.adb (Activation_Record_Component,
 211         Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
 212         Allow E_Discriminant.
 213
 214 2018-01-10  Eric Botcazou  <ebotcazou@adacore.com>
 215
 216         * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
 217         for atomic access once the component size is taken into account and
 218         also do it if the component type is Atomic or Volatile_Full_Access.
 219
 220 2018-01-04  Eric Botcazou  <ebotcazou@adacore.com>
 221
 222         * gnatvsn.ads: Bump copyright year.
 223
 224 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 225             Alan Hayward  <alan.hayward@arm.com>
 226             David Sherwood  <david.sherwood@arm.com>
 227
 228         * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_BITSIZE
 229         as polynomial.
 230
 231 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 232             Alan Hayward  <alan.hayward@arm.com>
 233             David Sherwood  <david.sherwood@arm.com>
 234
 235         * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_PRECISION
 236         as polynomial.
 237
 238 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 239             Alan Hayward  <alan.hayward@arm.com>
 240             David Sherwood  <david.sherwood@arm.com>
 241
 242         * gcc-interface/utils.c (gnat_types_compatible_p): Handle
 243         polynomial TYPE_VECTOR_SUBPARTS.
 244
 245 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 246             Alan Hayward  <alan.hayward@arm.com>
 247             David Sherwood  <david.sherwood@arm.com>
 248
 249         * gcc-interface/misc.c (enumerate_modes): Handle polynomial
 250         GET_MODE_NUNITS.
