   2
   3         * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
   4
   5 2018-01-11  Bob Duff  <duff@adacore.com>
   6
   7         * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
   8         to match what the Libadalang-based version does.
   9         * doc/gnat_ugn/about_this_guide.rst: Update reference.
  10
  11 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
  12
  13         * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
  14         if it contains at least one component declaration employing a function
  15         call returning on the secondary stack.
  16
  17 2018-01-11  Yannick Moy  <moy@adacore.com>
  18
  19         * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
  20         Update description of restriction SPARK_05 with SPARK 2014.
  21         * gnat_rm.texi: Regenerate.
  22
  23 2018-01-11  Vasiliy Fofanov  <fofanov@adacore.com>
  24
  25         * doc/gnat_ugn/gnat_utility_programs.rst: Fix layout.
  26
  27 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
  28
  29         * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
  30         sem_res.adb, sem_util.adb: Minor reformatting.
  31
  32 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
  33
  34         * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
  35         has a delayed aspect which must be processed at the point the type is
  36         frozen. This mimics what is done when the predicate is provided by a
  37         source aspect.
  38
  39 2018-01-11  Doug Rupp  <rupp@adacore.com>
  40
  41         * init.c (vxworks): Add macro checks for __aarch64__.
  42
  43 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
  44
  45         * exp_util.adb (Add_Failure_Expression): New routine.
  46         (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
  47         * sem_util.adb (Is_Current_Instance): Code cleanup.
  48
  49 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
  50
  51         * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
  52         Default_Sec_Stack_Size.
  53         * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
  54         limit check so that the integer index does not overflow. Check the
  55         dynamic stack allocation does not cause the secondary stack pointer to
  56         overflow.
  57         (SS_Info): Align colons.
  58         (SS_Init): Cover the case when bootstraping with an old compiler that
  59         does not set Default_SS_Size.
  60
  61 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
  62
  63         * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
  64         legality of an inherited operation that may require overriding, ignore
  65         primitive_wrappers that correspond to explicit operations that override
  66         an interface primitive.
  67         * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
  68         operation to which the class-wide expression applies is a protected op.
  69         with a primitive_wrapper, verify that the updated inherited expression
  70         does not contain an internal call to a protected function.  This
  71         completes the implementation of AI12-0166.
  72
  73 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
  74
  75         * ali.adb: Document the remaining letters available for ALI lines.
  76         (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
  77         * ali.ads: Update type With_Record. Field
  78         Implicit_With_From_Instantiation is no longer in use. Add field
  79         Implicit_With.
  80         * csinfo.adb (CSinfo): Remove the setup for attribute
  81         Implicit_With_From_Instantiation.
  82         * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
  83         either implicitly or explicitly withed.
  84         (Is_Implicit_With_Clause): New routine.
  85         (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
  86         confusion with the with clause attribute by the same name.
  87         (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
  88         * rtsfind.adb (Maybe_Add_With): Code cleanup.
  89         * sem_ch8.adb (Present_System_Aux): Code cleanup.
  90         * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
  91         for a parent unit.
  92         (Implicit_With_On_Parent): Mark the with clause as generated for a
  93         parent unit.
  94         * sem_ch12.adb (Inherit_Context): With clauses inherited by an
  95         instantiation are no longer marked as Implicit_With_From_Instantiation
  96         because they are already marked as implicit.
  97         * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
  98         which marks implicit with clauses as related to an instantiation.
  99         * sinfo.adb (Implicit_With_From_Instantiation): Removed.
 100         (Parent_With): New routine.
 101         (Set_Implicit_With_From_Instantiation): Removed.
 102         (Set_Parent_With): New routine.
 103         * sinfo.ads: Update the documentation of attribute Implicit_With.
 104         Remove attribute Implicit_With_From_Instantiation along with
 105         occurrences in nodes.  Add attribute Parent_With along with occurrences
 106         in nodes.
 107         (Implicit_With_From_Instantiation): Removed along with pragma Inline.
 108         (Parent_With): New routine along with pragma Inline.
 109         (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
 110         (Set_Parent_With): New routine along with pragma Inline.
 111
 112 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 113
 114         * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
 115         entity when the enclosing construct is a body.
 116
 117 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
 118
 119         * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
 120         Secondary_Stack_Size handling as a pragma is now generated for the
 121         corresponding aspect instead of an attribute.  Pragma expression is
 122         relocated instead of evaluated. Discriminant of the corresponding
 123         record type is referenced rather than the type discriminant.
 124         (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
 125         Secondary_Stack_Size rep item checks to only look for the pragma rep.
 126         * sem_ch13.adb (Analyze_One_Aspect): Transform
 127         Aspect_Secondary_Stack_Size into a pragma instead of an attribute
 128         because the attribute does not have visibility on a task type's
 129         discriminants when the type's definition is expanded.
 130         (Analyze_Attribute_Definition_Clause): Remove handling of
 131         Attribute_Secondary_Stack_Size.
 132         * snames.adb-tmpl, snames.ads-tmpl: Remove
 133         Attribute_Secondary_Stack_Size, no longer used.
 134
 135 2018-01-11  Justin Squirek  <squirek@adacore.com>
 136
 137         * sem_ch8.adb: Minor comment fix.
 138
 139 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 140
 141         * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
 142         individual action because the action may denote a complex expression,
 143         such as a case statement, which in turn may contain additional
 144         transient objects.
 145
 146 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
 147
 148         * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
 149         analysis on a copy of the expression with a copy of the index variable,
 150         because full expansion will rewrite construct into a loop with the
 151         original loop variable.
 152         * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
 153         expression is an iterated component association. Full analysis takes
 154         place when construct is rewritten as a loop.
 155         (In_Place_Assign_OK, Safe_Component): An iterated_component_association
 156         is not safe for in-place assignment.
 157         * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
 158         entity with no homonym and no other entity in the scope.
 159
 160 2018-01-11  Justin Squirek  <squirek@adacore.com>
 161
 162         * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
 163         message to be printed on the pragma argument identifier.
 164
 165 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
 166
 167         * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
 168         entity of the generated invariant procedure in order to construct a
 169         proper entity chain.
 170
 171 2018-01-11  Piotr Trojanek  <trojanek@adacore.com>
 172
 173         * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
 174         comment.
 175
 176 2018-01-11  Arnaud Charlet  <charlet@adacore.com>
 177
 178         * einfo.ads, einfo.adb (Activation_Record_Component,
 179         Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
 180         Allow E_Discriminant.
 181
 182 2018-01-10  Eric Botcazou  <ebotcazou@adacore.com>
 183
 184         * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
 185         for atomic access once the component size is taken into account and
 186         also do it if the component type is Atomic or Volatile_Full_Access.
 187
 188 2018-01-04  Eric Botcazou  <ebotcazou@adacore.com>
 189
 190         * gnatvsn.ads: Bump copyright year.
 191
 192 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 193             Alan Hayward  <alan.hayward@arm.com>
 194             David Sherwood  <david.sherwood@arm.com>
 195
 196         * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_BITSIZE
 197         as polynomial.
 198
 199 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 200             Alan Hayward  <alan.hayward@arm.com>
 201             David Sherwood  <david.sherwood@arm.com>
 202
 203         * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_PRECISION
 204         as polynomial.
 205
 206 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 207             Alan Hayward  <alan.hayward@arm.com>
 208             David Sherwood  <david.sherwood@arm.com>
 209
 210         * gcc-interface/utils.c (gnat_types_compatible_p): Handle
 211         polynomial TYPE_VECTOR_SUBPARTS.
 212
 213 2018-01-03  Richard Sandiford  <richard.sandiford@linaro.org>
 214             Alan Hayward  <alan.hayward@arm.com>
 215             David Sherwood  <david.sherwood@arm.com>
 216
 217         * gcc-interface/misc.c (enumerate_modes): Handle polynomial
 218         GET_MODE_NUNITS.
