   1 2018-05-25  Nicolas Roche  <roche@adacore.com>
   2
   3         * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
   4         that the result will be either -infinite or +infinite.
   5
   6 2018-05-25  Patrick Bernardi  <bernardi@adacore.com>
   7
   8         * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,
   9         libgnat/s-parame__ae653.ads, libgnat/s-parame__hpux.ads (Size_Type):
  10         Expand range of type to match the address space of the target.
  11         (Task_Storage_Size): Remove unused type.
  12
  13 2018-05-25  Ed Schonberg  <schonberg@adacore.com>
  14
  15         * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
  16         of a fixed point type and the parent is a multiplying operation,
  17         resolve the operand with its own type because the context will impose a
  18         resulting type on the result of the multiplication by means of
  19         approriate conversion.
  20
  21 2018-05-25  Hristian Kirtchev  <kirtchev@adacore.com>
  22
  23         * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
  24         the in-place initialization aggregate created for pragmas
  25         Initialize_Scalars or Normalize_Scalars is performed with checks
  26         suppressed.
  27
  28 2018-05-25  Arnaud Charlet  <charlet@adacore.com>
  29
  30         * exp_aggr.adb (Convert_To_Positional): Bump default for
  31         Max_Others_Replicate to 32. Update comments.
  32         * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
  33         (No_File_Info_Cache): Initialize separately.
  34         * osint.adb (No_File_Info_Cache): Update initializer.
  35
  36 2018-05-25  Javier Miranda  <miranda@adacore.com>
  37
  38         * sem_res.adb (Resolve_Membership_Op): Allow the use of the membership
  39         test when the left operand is a class-wide interface and the right
  40         operand is not a class-wide type.
  41         * exp_ch4.adb (Tagged_Membership): Adding support for interface as the
  42         left operand.
  43
  44 2018-05-25  Ed Schonberg  <schonberg@adacore.com>
  45
  46         * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated
  47         in an others clause to prevent visibility issues with the generated
  48         loop variable.
  49         (Component_OK_For_Backend): Return false for a quantified expression.
  50         (Check_Static_Component): Ditto.
  51
  52 2018-05-25  Hristian Kirtchev  <kirtchev@adacore.com>
  53
  54         * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
  55         (SS_Allocate_Dynamic): New routine. The allocation logic is now split
  56         into three distring cases rather than in one loop which attempts to
  57         handle all three cases. This rewrite eliminates an issue where the last
  58         frame of the stack cannot be freed, thus causing the memory range of a
  59         new frame to approach the overflow point of the memory index type.
  60         Since the overflow is logically treated as a
  61         too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
  62         (SS_Allocate_Static): New routine. The routine factorizes the static
  63         secondary stack-related code from the former SS_Allocate.
  64
  65 2018-05-25  Sergey Rybin  <rybin@adacore.com>
  66
  67         * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
  68         option for gnatelim.
  69
  70 2018-05-25  Ed Schonberg  <schonberg@adacore.com>
  71
  72         * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
  73         Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
  74         is created when the proper body of the stub is analyzed.
  75         * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
  76         is the proper body of a subunit, the cloned body must be inserted in
  77         the declarative list that contains the stub.
  78
  79 2018-05-25  Justin Squirek  <squirek@adacore.com>
  80
  81         * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
  82         generate code for 6.5(8-10) so that we don't get an assertion error
  83         when dealing with an incomplete return type.
  84
  85 2018-05-25  Arnaud Charlet  <charlet@adacore.com>
  86
  87         * pprint.adb (Expression_Name): Strip too long expressions to avoid
  88         carrying very large strings.
  89
  90 2018-05-25  Patrick Bernardi  <bernardi@adacore.com>
  91
  92         * switch-b.adb (Scan_Binder_Switches): binder switch -Q accepts Natural
  93         numbers.
  94
  95 2018-05-25  Doug Rupp  <rupp@adacore.com>
  96
  97         * tracebak.c (aarch64-linux): Implement.
  98
  99 2018-05-25  Justin Squirek  <squirek@adacore.com>
 100
 101         * sem_ch8.adb: Minor reformatting.
 102
 103 2018-05-25  Piotr Trojanek  <trojanek@adacore.com>
 104
 105         * sem_util.adb (Iterate_Call_Parameters): Fix code convention and
 106         assertions.
 107
 108 2018-05-25  Hristian Kirtchev  <kirtchev@adacore.com>
 109
 110         * einfo.adb, einfo.ads, exp_ch3.adb, exp_ch8.adb, exp_unst.adb,
 111         pprint.adb, sem_ch12.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
 112         Minor reformatting.
 113
 114 2018-05-25  Ed Schonberg  <schonberg@adacore.com>
 115
 116         * sem_ch12.adb (Instance_Exists): New function, subsidiary of
 117         Validate_Derived_Type_Instance, to verify that all interfaces
 118         implemented by the formal type are also implemented by the actual. The
 119         verification is complicated when an interface of the formal is declared
 120         in a generic unit and the actual is declared in an instance of it.
 121         There is currently no mechanism to relate an interface declared within
 122         a generic to the corresponding interface in an instance, so we must
 123         traverse the list of interfaces of the actual, looking for a name
 124         match, and verifying that that interface is declared in an instance.
 125
 126 2018-05-25  Piotr Trojanek  <trojanek@adacore.com>
 127
 128         * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
 129         assertions; replace function versions of Next_Formal/Next_Actual with
 130         their procedural versions (which are more concise).
 131
 132 2018-05-25  Doug Rupp  <rupp@adacore.com>
 133
 134         * libgnarl/s-osinte__aix.ads, libgnarl/s-osinte__android.ads,

 140         * libgnarl/s-tpopmo.adb (Timed_Sleep, Timed_Delay): Rewrite to allow
 141         for incremental looping. Remove references to Rel_Time and
 142         Relative_Timed_Wait.
 143         * libgnat/s-osprim__posix.adb, libgnat/s-osprim__posix2008.adb
 144         (Timed_Delay): Make separate.
 145         * libgnat/s-optide.adb: New separate procedure.
 146         * libgnat/s-osprim.ads (Max_System_Delay): New constant.

 148         (Max_System_Delay): New constant.
 149
 150 2018-05-25  Ed Schonberg  <schonberg@adacore.com>
 151
 152         * sem_ch12.adb (Validate_Derived_Type_Instance): Verify that the actual
 153         for a formal derived type implements all the interfaces declared for
 154         the formal.
 155
 156 2018-05-25  Yannick Moy  <moy@adacore.com>
 157
 158         * sem_prag.adb (Check_Applicable_Policy): Deal specially with CodePeer
 159         and GNATprove modes when applicable policy is Ignore.
 160
 161 2018-05-25  Eric Botcazou  <ebotcazou@adacore.com>
 162
 163         * freeze.adb (Freeze_Enumeration_Type): Do not give integer size to a
 164         boolean type with convention C.
 165         * libgnat/i-cexten.ads (bool): Change to boolean with convention C.
 166         * gcc-interface/decl.c (gnat_to_gnu_entity): Add new local variable
 167         FOREIGN and use it throughout the function.

 169         convention.
 170         <E_Enumeration_Subtype>: Likewise for subtypes.
 171         <E_Record_Type>: Force the size of a storage unit on empty classes.
 172         * gcc-interface/utils.c (make_type_from_size) <BOOLEAN_TYPE>: Skip
 173         boolean types with precision 1 if the size is the expected one.
 174
 175 2018-05-25  Arnaud Charlet  <charlet@adacore.com>
 176
 177         * pprint.adb (Expression_Name): Do not print non ASCII characters.
 178
 179 2018-05-25  Bob Duff  <duff@adacore.com>
 180
 181         * libgnat/a-strunb__shared.ads, libgnat/a-stwiun__shared.ads,
 182         libgnat/a-stzunb__shared.ads: (Initialize, Adjust): Add pragma Inline.

 185
 186         * sem_util.ads: Minor comment fix.
 187
 188 2018-05-25  Ed Schonberg  <schonberg@adacore.com>
 189
 190         * exp_unst.adb (Visit_Node): Restrict check for uplevel references in
 191         prefixes of array attributes, to prefixes that are entity names whose
 192         type is constrained.
 193         (Note_Uplevel_Bound): Verify that the bound is declared in an enclosing
 194         subprogram, as itype created for loops in pre/postcondition may appear
 195         in loops at the library level.
 196
 197 2018-05-25  Ed Schonberg  <schonberg@adacore.com>
 198
 199         * sem_ch13.adb (Build_Predicate_Functions): The predicate function
 200         declaration is inserted into the tree and analyzed at that point, so
 201         should not be reinserted when the body is constructed. Inside a
 202         generic, ensure that the body is not inserted twice in the tree.
 203
 204 2018-05-25  Yannick Moy  <moy@adacore.com>

 241         (Expand_N_Subprogram_Renaming_Declaration): Adapt the code to the new
 242         implementation of Build_Body_For_Renaming.
 243         * exp_ch3.ads (Build_Variant_Record_Equality): New library level
 244         function that factorizes the functionality needed by
 245         Build_Body_For_Renaming and Expand_Freeze_Record_Type to build the body
 246         of a variant record equality subprogram.
 247         * exp_ch3.adb (Build_Variant_Record_Equality): New subprogram.
 248         (Build_Variant_Record_Equality): New local procedure of
 249         Expand_Freeze_Record_Type containing all the code specific for freezing
 250         the record type that cannot be place in the new library level function.
 251
 252 2018-05-24  Ed Schonberg  <schonberg@adacore.com>
 253
 254         * einfo.ads, einfo.adb (Is_Activation_Record): New flag on
 255         in_parameters, used when unesting subprograms for LLVM, to indicate
 256         that a generated parameter carries the activation record from the
 257         enclosing subprogram.
 258         * exp_unst.adb (Check_Static_Type): Handle array attributes of types
 259         whose bounds may contain up-level references that need to be added to

 279 2018-05-24  Ed Schonberg  <schonberg@adacore.com>
 280
 281         * sem_ch8.adb (Analyze_Use_Type): Do not assign the Prev_Use_Clause
 282         link to a use_type clause if this would cause an infinite loop in the
 283         machinery that detects redundant use clauses. This may happen when the
 284         redundant clauses appear in the context of a child unit and the context
 285         of its parent.
 286
 287 2018-05-24  Piotr Trojanek  <trojanek@adacore.com>
 288
 289         * sinfo.ads: Fix grammar in comment.

 292
 293         * einfo.ads, einfo.adb (Append_Entity): Modified to use Link_Entities
 294         and manage doubly-linked entity chain.
 295         (Nested_Scenarios): Removed entity field used for optimization during
 296          elaboration to make room for the new field Prev_Entity.
 297         (Link_Entities): Added to replace redundant calls to Set_Next_Entity
 298         and Set_Prev_Entity as well as centralize changes to the entity chain.
 299         (Predicated_Parent): Modified to use Node38.
 300         (Prev_Entity): Added to fetch new node field Prev_Entity in all entity

 302         (Remove_Entity): Moved from sem_util.
 303         (Set_Nested_Scenarios): Deleted.

 306         (Set_Validated_Object): Modified to use Node38.
 307         (Unlink_Next_Entity): Added to process Prev_Entity when an unlinking
 308         action is required.
 309         (Validated_Object): Modified to use Node38.
 310         (Write_Field36_Name): Remove Nested_Scenarios, Validated_Object, and

 319         w/ Link_Entities.
 320         (New_Overloaded_Entity): Remove block created to search for previous
 321         entities in the entity chain with relevant calls to Prev_Entity as well
 322         as replace duplicated code from Remove_Entity_And_Homonym with a call
 323         to that subprogram.
 324         * sem_ch7.adb (Exchange_Declarations): Replace Set_Next_Entity w/
 325         Link_Entities.

 697         must also suppress the generation of freeze nodes, which may otherwise

1359

1361         delegate the secondary stack management when there is no suitable
1362         transient context, and the transient scope was intended to manage the
1363         secondary stack because this causes premature reclamation. Change the

1727
1728         * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
1729         legality of an inherited operation that may require overriding, ignore
1730         primitive_wrappers that correspond to explicit operations that override
1731         an interface primitive.
1732         * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
1733         operation to which the class-wide expression applies is a protected op.
1734         with a primitive_wrapper, verify that the updated inherited expression
1735         does not contain an internal call to a protected function.  This
1736         completes the implementation of AI12-0166.
1737
1738 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
1739
1740         * ali.adb: Document the remaining letters available for ALI lines.
1741         (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
1742         * ali.ads: Update type With_Record. Field
1743         Implicit_With_From_Instantiation is no longer in use. Add field
1744         Implicit_With.
1745         * csinfo.adb (CSinfo): Remove the setup for attribute
1746         Implicit_With_From_Instantiation.
1747         * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
1748         either implicitly or explicitly withed.
1749         (Is_Implicit_With_Clause): New routine.
1750         (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
1751         confusion with the with clause attribute by the same name.
1752         (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
1753         * rtsfind.adb (Maybe_Add_With): Code cleanup.
1754         * sem_ch8.adb (Present_System_Aux): Code cleanup.
1755         * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
1756         for a parent unit.
1757         (Implicit_With_On_Parent): Mark the with clause as generated for a
1758         parent unit.
1759         * sem_ch12.adb (Inherit_Context): With clauses inherited by an
1760         instantiation are no longer marked as Implicit_With_From_Instantiation
1761         because they are already marked as implicit.
1762         * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
1763         which marks implicit with clauses as related to an instantiation.
1764         * sinfo.adb (Implicit_With_From_Instantiation): Removed.
1765         (Parent_With): New routine.
1766         (Set_Implicit_With_From_Instantiation): Removed.
1767         (Set_Parent_With): New routine.
1768         * sinfo.ads: Update the documentation of attribute Implicit_With.
1769         Remove attribute Implicit_With_From_Instantiation along with
1770         occurrences in nodes.  Add attribute Parent_With along with occurrences
1771         in nodes.
1772         (Implicit_With_From_Instantiation): Removed along with pragma Inline.
1773         (Parent_With): New routine along with pragma Inline.
1774         (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
1775         (Set_Parent_With): New routine along with pragma Inline.

1778
1779         * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
1780         entity when the enclosing construct is a body.
1781
1782 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
1783
1784         * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
1785         Secondary_Stack_Size handling as a pragma is now generated for the
1786         corresponding aspect instead of an attribute.  Pragma expression is
1787         relocated instead of evaluated. Discriminant of the corresponding
1788         record type is referenced rather than the type discriminant.
1789         (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
1790         Secondary_Stack_Size rep item checks to only look for the pragma rep.
1791         * sem_ch13.adb (Analyze_One_Aspect): Transform
1792         Aspect_Secondary_Stack_Size into a pragma instead of an attribute
1793         because the attribute does not have visibility on a task type's
1794         discriminants when the type's definition is expanded.
1795         (Analyze_Attribute_Definition_Clause): Remove handling of
1796         Attribute_Secondary_Stack_Size.
1797         * snames.adb-tmpl, snames.ads-tmpl: Remove
1798         Attribute_Secondary_Stack_Size, no longer used.

1803
1804 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
1805
1806         * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
1807         individual action because the action may denote a complex expression,
1808         such as a case statement, which in turn may contain additional
1809         transient objects.
1810
1811 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
1812
1813         * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
1814         analysis on a copy of the expression with a copy of the index variable,
1815         because full expansion will rewrite construct into a loop with the
1816         original loop variable.
1817         * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
1818         expression is an iterated component association. Full analysis takes
1819         place when construct is rewritten as a loop.
1820         (In_Place_Assign_OK, Safe_Component): An iterated_component_association
1821         is not safe for in-place assignment.
1822         * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
1823         entity with no homonym and no other entity in the scope.
1824

1831
1832         * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
1833         entity of the generated invariant procedure in order to construct a
1834         proper entity chain.
1835
1836 2018-01-11  Piotr Trojanek  <trojanek@adacore.com>
1837

1843         * einfo.ads, einfo.adb (Activation_Record_Component,
1844         Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
1845         Allow E_Discriminant.
1846

1848
1849         * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
1850         for atomic access once the component size is taken into account and
1851         also do it if the component type is Atomic or Volatile_Full_Access.
1852
1853 2018-01-04  Eric Botcazou  <ebotcazou@adacore.com>
