gcc/ada/ChangeLog

   1 2018-05-28  Justin Squirek  <squirek@adacore.com>
   2
   3         * sem_ch8.adb (Find_Expanded_Name): Add extra guard to make sure the
   4         misresolved package name is not a case of mistaken identity.
   5
   6 2018-05-28  Yannick Moy  <moy@adacore.com>
   7
   8         * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
   9         GNATprove mode, as the order of resolution (low then high) means that
  10         all the information is not available when resolving the low bound the
  11         first time.
  12
  13 2018-05-28  Eric Botcazou  <ebotcazou@adacore.com>
  14
  15         * repinfo.adb (List_Array_Info): Start with an explicit blank line and
  16         end with the linker section, if any.
  17         (List_Entities): Do not output the linker section for record types,
  18         array types and variables.
  19         (Print_Expr): Factor out common processing for unary operators and
  20         special values.  Adjust and reorder the various cases.
  21         (List_Object_Info): End with the linker section, if any.
  22         (List_Record_Info): Likewise.
  23         (List_Type_Info): Do not start with a blank line.
  24
  25 2018-05-25  Nicolas Roche  <roche@adacore.com>
  26
  27         * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
  28         that the result will be either -infinite or +infinite.
  29
  30 2018-05-25  Patrick Bernardi  <bernardi@adacore.com>
  31
  32         * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,
  33         libgnat/s-parame__ae653.ads, libgnat/s-parame__hpux.ads (Size_Type):
  34         Expand range of type to match the address space of the target.
  35         (Task_Storage_Size): Remove unused type.
  36
  37 2018-05-25  Ed Schonberg  <schonberg@adacore.com>
  38
  39         * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
  40         of a fixed point type and the parent is a multiplying operation,
  41         resolve the operand with its own type because the context will impose a
  42         resulting type on the result of the multiplication by means of
  43         approriate conversion.
  44
  45 2018-05-25  Hristian Kirtchev  <kirtchev@adacore.com>
  46
  47         * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
  48         the in-place initialization aggregate created for pragmas
  49         Initialize_Scalars or Normalize_Scalars is performed with checks
  50         suppressed.
  51
  52 2018-05-25  Arnaud Charlet  <charlet@adacore.com>
  53
  54         * exp_aggr.adb (Convert_To_Positional): Bump default for
  55         Max_Others_Replicate to 32. Update comments.
  56         * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
  57         (No_File_Info_Cache): Initialize separately.
  58         * osint.adb (No_File_Info_Cache): Update initializer.
  59
  60 2018-05-25  Javier Miranda  <miranda@adacore.com>
  61
  62         * sem_res.adb (Resolve_Membership_Op): Allow the use of the membership
  63         test when the left operand is a class-wide interface and the right
  64         operand is not a class-wide type.
  65         * exp_ch4.adb (Tagged_Membership): Adding support for interface as the
  66         left operand.
  67
  68 2018-05-25  Ed Schonberg  <schonberg@adacore.com>
  69
  70         * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated
  71         in an others clause to prevent visibility issues with the generated
  72         loop variable.
  73         (Component_OK_For_Backend): Return false for a quantified expression.
  74         (Check_Static_Component): Ditto.
  75
  76 2018-05-25  Hristian Kirtchev  <kirtchev@adacore.com>
  77
  78         * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
  79         (SS_Allocate_Dynamic): New routine. The allocation logic is now split
  80         into three distring cases rather than in one loop which attempts to
  81         handle all three cases. This rewrite eliminates an issue where the last
  82         frame of the stack cannot be freed, thus causing the memory range of a
  83         new frame to approach the overflow point of the memory index type.
  84         Since the overflow is logically treated as a
  85         too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
  86         (SS_Allocate_Static): New routine. The routine factorizes the static
  87         secondary stack-related code from the former SS_Allocate.
  88
  89 2018-05-25  Sergey Rybin  <rybin@adacore.com>
  90
  91         * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
  92         option for gnatelim.
  93
  94 2018-05-25  Ed Schonberg  <schonberg@adacore.com>
  95
  96         * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
  97         Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
  98         is created when the proper body of the stub is analyzed.
  99         * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
 100         is the proper body of a subunit, the cloned body must be inserted in
 101         the declarative list that contains the stub.
 102
 103 2018-05-25  Justin Squirek  <squirek@adacore.com>
 104
 105         * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
 106         generate code for 6.5(8-10) so that we don't get an assertion error
 107         when dealing with an incomplete return type.
 108
 109 2018-05-25  Arnaud Charlet  <charlet@adacore.com>
 110
 111         * pprint.adb (Expression_Name): Strip too long expressions to avoid
 112         carrying very large strings.
 113
 114 2018-05-25  Patrick Bernardi  <bernardi@adacore.com>
 115
 116         * switch-b.adb (Scan_Binder_Switches): binder switch -Q accepts Natural
 117         numbers.
 118
 119 2018-05-25  Doug Rupp  <rupp@adacore.com>
 120
 121         * tracebak.c (aarch64-linux): Implement.
 122
 123 2018-05-25  Justin Squirek  <squirek@adacore.com>
 124
 125         * sem_ch8.adb: Minor reformatting.
 126
 127 2018-05-25  Piotr Trojanek  <trojanek@adacore.com>
 128
 129         * sem_util.adb (Iterate_Call_Parameters): Fix code convention and
 130         assertions.
 131
 132 2018-05-25  Hristian Kirtchev  <kirtchev@adacore.com>
 133
 134         * einfo.adb, einfo.ads, exp_ch3.adb, exp_ch8.adb, exp_unst.adb,
 135         pprint.adb, sem_ch12.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
 136         Minor reformatting.
 137
 138 2018-05-25  Ed Schonberg  <schonberg@adacore.com>
 139
 140         * sem_ch12.adb (Instance_Exists): New function, subsidiary of
 141         Validate_Derived_Type_Instance, to verify that all interfaces
 142         implemented by the formal type are also implemented by the actual. The
 143         verification is complicated when an interface of the formal is declared
 144         in a generic unit and the actual is declared in an instance of it.
 145         There is currently no mechanism to relate an interface declared within
 146         a generic to the corresponding interface in an instance, so we must
 147         traverse the list of interfaces of the actual, looking for a name
 148         match, and verifying that that interface is declared in an instance.
 149
 150 2018-05-25  Piotr Trojanek  <trojanek@adacore.com>
 151
 152         * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
 153         assertions; replace function versions of Next_Formal/Next_Actual with
 154         their procedural versions (which are more concise).
 155
 156 2018-05-25  Doug Rupp  <rupp@adacore.com>
 157
 158         * libgnarl/s-osinte__aix.ads, libgnarl/s-osinte__android.ads,

 164         * libgnarl/s-tpopmo.adb (Timed_Sleep, Timed_Delay): Rewrite to allow
 165         for incremental looping. Remove references to Rel_Time and
 166         Relative_Timed_Wait.
 167         * libgnat/s-osprim__posix.adb, libgnat/s-osprim__posix2008.adb
 168         (Timed_Delay): Make separate.
 169         * libgnat/s-optide.adb: New separate procedure.
 170         * libgnat/s-osprim.ads (Max_System_Delay): New constant.

 172         (Max_System_Delay): New constant.
 173
 174 2018-05-25  Ed Schonberg  <schonberg@adacore.com>
 175
 176         * sem_ch12.adb (Validate_Derived_Type_Instance): Verify that the actual
 177         for a formal derived type implements all the interfaces declared for
 178         the formal.
 179
 180 2018-05-25  Yannick Moy  <moy@adacore.com>
 181
 182         * sem_prag.adb (Check_Applicable_Policy): Deal specially with CodePeer
 183         and GNATprove modes when applicable policy is Ignore.
 184

 186
 187         * freeze.adb (Freeze_Enumeration_Type): Do not give integer size to a
 188         boolean type with convention C.
 189         * libgnat/i-cexten.ads (bool): Change to boolean with convention C.
 190         * gcc-interface/decl.c (gnat_to_gnu_entity): Add new local variable
 191         FOREIGN and use it throughout the function.

 193         convention.
 194         <E_Enumeration_Subtype>: Likewise for subtypes.
 195         <E_Record_Type>: Force the size of a storage unit on empty classes.
 196         * gcc-interface/utils.c (make_type_from_size) <BOOLEAN_TYPE>: Skip
 197         boolean types with precision 1 if the size is the expected one.
 198
 199 2018-05-25  Arnaud Charlet  <charlet@adacore.com>
 200
 201         * pprint.adb (Expression_Name): Do not print non ASCII characters.
 202
 203 2018-05-25  Bob Duff  <duff@adacore.com>
 204
 205         * libgnat/a-strunb__shared.ads, libgnat/a-stwiun__shared.ads,
 206         libgnat/a-stzunb__shared.ads: (Initialize, Adjust): Add pragma Inline.

 208 2018-05-25  Bob Duff  <duff@adacore.com>
 209
 210         * sem_util.ads: Minor comment fix.
 211

 215         prefixes of array attributes, to prefixes that are entity names whose
 216         type is constrained.
 217         (Note_Uplevel_Bound): Verify that the bound is declared in an enclosing
 218         subprogram, as itype created for loops in pre/postcondition may appear
 219         in loops at the library level.
 220
 221 2018-05-25  Ed Schonberg  <schonberg@adacore.com>
 222
 223         * sem_ch13.adb (Build_Predicate_Functions): The predicate function
 224         declaration is inserted into the tree and analyzed at that point, so
 225         should not be reinserted when the body is constructed. Inside a
 226         generic, ensure that the body is not inserted twice in the tree.
 227
 228 2018-05-25  Yannick Moy  <moy@adacore.com>
 229
 230         * sem_prag.adb (Check_Grouping): Modify test to ignore statements and

 265         (Expand_N_Subprogram_Renaming_Declaration): Adapt the code to the new
 266         implementation of Build_Body_For_Renaming.
 267         * exp_ch3.ads (Build_Variant_Record_Equality): New library level
 268         function that factorizes the functionality needed by
 269         Build_Body_For_Renaming and Expand_Freeze_Record_Type to build the body
 270         of a variant record equality subprogram.
 271         * exp_ch3.adb (Build_Variant_Record_Equality): New subprogram.
 272         (Build_Variant_Record_Equality): New local procedure of
 273         Expand_Freeze_Record_Type containing all the code specific for freezing
 274         the record type that cannot be place in the new library level function.
 275
 276 2018-05-24  Ed Schonberg  <schonberg@adacore.com>
 277
 278         * einfo.ads, einfo.adb (Is_Activation_Record): New flag on
 279         in_parameters, used when unesting subprograms for LLVM, to indicate
 280         that a generated parameter carries the activation record from the
 281         enclosing subprogram.
 282         * exp_unst.adb (Check_Static_Type): Handle array attributes of types
 283         whose bounds may contain up-level references that need to be added to

 286
 287 2018-05-24  Yannick Moy  <moy@adacore.com>
 288
 289         * pprint.adb (Expression_Image): Improve the printing of expressions,
 290         by taking more cases into account, in particular qualified expressions
 291         and aggregates.  Also count more the number of parentheses to close
 292         after the expression.

 303 2018-05-24  Ed Schonberg  <schonberg@adacore.com>
 304
 305         * sem_ch8.adb (Analyze_Use_Type): Do not assign the Prev_Use_Clause
 306         link to a use_type clause if this would cause an infinite loop in the
 307         machinery that detects redundant use clauses. This may happen when the
 308         redundant clauses appear in the context of a child unit and the context
 309         of its parent.
 310
 311 2018-05-24  Piotr Trojanek  <trojanek@adacore.com>
 312
 313         * sinfo.ads: Fix grammar in comment.
 314
 315 2018-05-24  Justin Squirek  <squirek@adacore.com>
 316
 317         * einfo.ads, einfo.adb (Append_Entity): Modified to use Link_Entities
 318         and manage doubly-linked entity chain.
 319         (Nested_Scenarios): Removed entity field used for optimization during
 320          elaboration to make room for the new field Prev_Entity.
 321         (Link_Entities): Added to replace redundant calls to Set_Next_Entity
 322         and Set_Prev_Entity as well as centralize changes to the entity chain.
 323         (Predicated_Parent): Modified to use Node38.
 324         (Prev_Entity): Added to fetch new node field Prev_Entity in all entity
 325         types.
 326         (Remove_Entity): Moved from sem_util.
 327         (Set_Nested_Scenarios): Deleted.
 328         (Set_Predicated_Parent): Modified to use Node38.
 329         (Set_Prev_Entity): Added to set Prev_Entity field.
 330         (Set_Validated_Object): Modified to use Node38.
 331         (Unlink_Next_Entity): Added to process Prev_Entity when an unlinking
 332         action is required.
 333         (Validated_Object): Modified to use Node38.
 334         (Write_Field36_Name): Remove Nested_Scenarios, Validated_Object, and
 335         predicated parent cases.

 342         * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Replace Set_Next_Entity
 343         w/ Link_Entities.
 344         (New_Overloaded_Entity): Remove block created to search for previous
 345         entities in the entity chain with relevant calls to Prev_Entity as well
 346         as replace duplicated code from Remove_Entity_And_Homonym with a call
 347         to that subprogram.
 348         * sem_ch7.adb (Exchange_Declarations): Replace Set_Next_Entity w/
 349         Link_Entities.

 720         while-loop during expansion. The pre-analysis suppresses expansion; it
 721         must also suppress the generation of freeze nodes, which may otherwise
 722         appear in the wrong scope before rewritting.

1386         transient context, and the transient scope was intended to manage the
1387         secondary stack because this causes premature reclamation. Change the
1388         transient scope creation logic by special casing assignment statements
1389         of controlled components for type initialization procedures.

1393         Iterations schemes and iterator specifications are not valid transient
1394         contexts because they rely on special processing. Assignment statements
1395         are now treated as a normal transient context, special cases are
1396         handled by the caller. Add special processing for pragma Check.

1402         the secondary stack.

1726         source aspect.

1728 2018-01-11  Doug Rupp  <rupp@adacore.com>
1729
1730         * init.c (vxworks): Add macro checks for __aarch64__.
1731
1732 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
1733
1734         * exp_util.adb (Add_Failure_Expression): New routine.
1735         (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
1736         * sem_util.adb (Is_Current_Instance): Code cleanup.
1737
1738 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
1739
1740         * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
1741         Default_Sec_Stack_Size.
1742         * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
1743         limit check so that the integer index does not overflow. Check the
1744         dynamic stack allocation does not cause the secondary stack pointer to
1745         overflow.
1746         (SS_Info): Align colons.
1747         (SS_Init): Cover the case when bootstraping with an old compiler that
1748         does not set Default_SS_Size.
1749
1750 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
1751
1752         * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
1753         legality of an inherited operation that may require overriding, ignore
1754         primitive_wrappers that correspond to explicit operations that override
1755         an interface primitive.
1756         * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
1757         operation to which the class-wide expression applies is a protected op.
1758         with a primitive_wrapper, verify that the updated inherited expression
1759         does not contain an internal call to a protected function.  This
1760         completes the implementation of AI12-0166.
1761
1762 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
1763
1764         * ali.adb: Document the remaining letters available for ALI lines.
1765         (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
1766         * ali.ads: Update type With_Record. Field
1767         Implicit_With_From_Instantiation is no longer in use. Add field
1768         Implicit_With.
1769         * csinfo.adb (CSinfo): Remove the setup for attribute
1770         Implicit_With_From_Instantiation.
1771         * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
1772         either implicitly or explicitly withed.
1773         (Is_Implicit_With_Clause): New routine.
1774         (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
1775         confusion with the with clause attribute by the same name.
1776         (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
1777         * rtsfind.adb (Maybe_Add_With): Code cleanup.
1778         * sem_ch8.adb (Present_System_Aux): Code cleanup.
1779         * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
1780         for a parent unit.
1781         (Implicit_With_On_Parent): Mark the with clause as generated for a
1782         parent unit.
1783         * sem_ch12.adb (Inherit_Context): With clauses inherited by an
1784         instantiation are no longer marked as Implicit_With_From_Instantiation
1785         because they are already marked as implicit.
1786         * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
1787         which marks implicit with clauses as related to an instantiation.
1788         * sinfo.adb (Implicit_With_From_Instantiation): Removed.
1789         (Parent_With): New routine.
1790         (Set_Implicit_With_From_Instantiation): Removed.
1791         (Set_Parent_With): New routine.
1792         * sinfo.ads: Update the documentation of attribute Implicit_With.
1793         Remove attribute Implicit_With_From_Instantiation along with
1794         occurrences in nodes.  Add attribute Parent_With along with occurrences
1795         in nodes.
1796         (Implicit_With_From_Instantiation): Removed along with pragma Inline.
1797         (Parent_With): New routine along with pragma Inline.
1798         (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
1799         (Set_Parent_With): New routine along with pragma Inline.
1800
1801 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
1802
1803         * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
1804         entity when the enclosing construct is a body.
1805
1806 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
1807
1808         * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
1809         Secondary_Stack_Size handling as a pragma is now generated for the
1810         corresponding aspect instead of an attribute.  Pragma expression is
1811         relocated instead of evaluated. Discriminant of the corresponding
1812         record type is referenced rather than the type discriminant.
1813         (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
1814         Secondary_Stack_Size rep item checks to only look for the pragma rep.
1815         * sem_ch13.adb (Analyze_One_Aspect): Transform
1816         Aspect_Secondary_Stack_Size into a pragma instead of an attribute
1817         because the attribute does not have visibility on a task type's
1818         discriminants when the type's definition is expanded.
1819         (Analyze_Attribute_Definition_Clause): Remove handling of
1820         Attribute_Secondary_Stack_Size.
1821         * snames.adb-tmpl, snames.ads-tmpl: Remove
1822         Attribute_Secondary_Stack_Size, no longer used.
1823
1824 2018-01-11  Justin Squirek  <squirek@adacore.com>
1825
1826         * sem_ch8.adb: Minor comment fix.
1827
1828 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
1829
1830         * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
1831         individual action because the action may denote a complex expression,
1832         such as a case statement, which in turn may contain additional
1833         transient objects.
1834
1835 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
1836
1837         * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
1838         analysis on a copy of the expression with a copy of the index variable,
1839         because full expansion will rewrite construct into a loop with the
1840         original loop variable.
1841         * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
1842         expression is an iterated component association. Full analysis takes
1843         place when construct is rewritten as a loop.
1844         (In_Place_Assign_OK, Safe_Component): An iterated_component_association
1845         is not safe for in-place assignment.
1846         * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
1847         entity with no homonym and no other entity in the scope.
1848
1849 2018-01-11  Justin Squirek  <squirek@adacore.com>
1850
1851         * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
1852         message to be printed on the pragma argument identifier.
1853
1854 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
1855
1856         * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
1857         entity of the generated invariant procedure in order to construct a
1858         proper entity chain.
1859
1860 2018-01-11  Piotr Trojanek  <trojanek@adacore.com>
1861

1863         comment.
1864
1865 2018-01-11  Arnaud Charlet  <charlet@adacore.com>
1866
1867         * einfo.ads, einfo.adb (Activation_Record_Component,
1868         Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
1869         Allow E_Discriminant.
1870

1872
1873         * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
1874         for atomic access once the component size is taken into account and
1875         also do it if the component type is Atomic or Volatile_Full_Access.
1876
1877 2018-01-04  Eric Botcazou  <ebotcazou@adacore.com>
