3 * exp_unst.adb (Visit_Node): Exclude selected components whose prefix
4 carry no type. Such selected components appear in unit names that are
5 child units, both in the specification and possibly in an end label for
6 the unit, and they do not contain any relevant uplevel references.

204 of actual have uplevel references.
206 2018-05-28 Ed Schonberg <schonberg@adacore.com>
208 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus

228 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
229 value when converting a float value to a fixed-point value. This is
230 required for CCG because it handles fixed-point types by means of
231 unsigned integer type variables. The range check is now performed using
232 the integer value stored in this temporary.
234 2018-05-28 Yannick Moy <moy@adacore.com>
236 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and
237 Length as valid non-interfering contexts for SPARK.

241 * sem_disp.ads, sem_disp.adb (Inheritance_Utilities): Package for
242 generic inheritance utilities.
243 (Generic_Inherited_Subprograms): Generic version of
244 Inherited_Subprograms, generic in Find_Dispatching_Type function.
245 (Generic_Is_Overriding_Subprogram): Generic version of
246 Is_Overriding_Subprogram, generic in Find_Dispatching_Type function.

258 base type, except for the case where the bounds of the type depend on a

263 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
264 access-to-subprogram types, to indicate that an indirect call through
265 such a type requires an activation record when compiling for LLVM.
266 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
268 2018-05-28 Ed Schonberg <schonberg@adacore.com>
270 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
271 when bounds of fixed type are static, to remove some spuerfluous
272 implicit conversions and provide an accurate result when converting
273 back and forth between the fixed point type and a floating point type.
275 2018-05-28 Ed Schonberg <schonberg@adacore.com>
277 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
280 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
282 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
283 replaced, if any; all callers changed.
284 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
285 constant with private view so we take the address of that entity.
286 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
287 any; all callers changed. Handle N_Indexed_Component like
288 N_Attribute_Reference. Add N_Type_Conversion case.
289 (Visit_Node): Indexed references can be uplevel if the type isn't
291 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
292 been relocated, set first_named pointer in original node as well.
294 2018-05-28 Ed Schonberg <schonberg@adacore.com>
296 * exp_aggr.adb (Flatten): Copy tree of expression in a component
297 association with a range or a set of discrete choices, rather than
298 relocating the node. This avoids inconsistencies in the tree when
299 handling nested subprograms with uplevel references for LLVM.

313 unnecessary use of 'Unrestricted_Access.

365 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
366 includes a call to function to which it applies. This may mean an
367 omission of an attribute reference 'Result, in particular if the
368 function is pqrameterless.

384 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
385 end with the linker section, if any.
386 (List_Entities): Do not output the linker section for record types,
387 array types and variables.
388 (Print_Expr): Factor out common processing for unary operators and
389 special values. Adjust and reorder the various cases.
390 (List_Object_Info): End with the linker section, if any.

397 that the result will be either -infinite or +infinite.

401 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,

403 Expand range of type to match the address space of the target.
404 (Task_Storage_Size): Remove unused type.
406 2018-05-25 Ed Schonberg <schonberg@adacore.com>
408 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
409 of a fixed point type and the parent is a multiplying operation,
410 resolve the operand with its own type because the context will impose a
411 resulting type on the result of the multiplication by means of
412 approriate conversion.
414 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
416 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
417 the in-place initialization aggregate created for pragmas
418 Initialize_Scalars or Normalize_Scalars is performed with checks
421 2018-05-25 Arnaud Charlet <charlet@adacore.com>
423 * exp_aggr.adb (Convert_To_Positional): Bump default for
424 Max_Others_Replicate to 32. Update comments.
425 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
426 (No_File_Info_Cache): Initialize separately.

445 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
447 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
448 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
449 into three distring cases rather than in one loop which attempts to
450 handle all three cases. This rewrite eliminates an issue where the last
451 frame of the stack cannot be freed, thus causing the memory range of a
452 new frame to approach the overflow point of the memory index type.
453 Since the overflow is logically treated as a
454 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
455 (SS_Allocate_Static): New routine. The routine factorizes the static
456 secondary stack-related code from the former SS_Allocate.
458 2018-05-25 Sergey Rybin <rybin@adacore.com>
460 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'

465 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
466 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
467 is created when the proper body of the stub is analyzed.
468 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
469 is the proper body of a subunit, the cloned body must be inserted in
470 the declarative list that contains the stub.
472 2018-05-25 Justin Squirek <squirek@adacore.com>
474 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
475 generate code for 6.5(8-10) so that we don't get an assertion error
476 when dealing with an incomplete return type.
478 2018-05-25 Arnaud Charlet <charlet@adacore.com>

481 carrying very large strings.

509 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
510 Validate_Derived_Type_Instance, to verify that all interfaces
511 implemented by the formal type are also implemented by the actual. The
512 verification is complicated when an interface of the formal is declared
513 in a generic unit and the actual is declared in an instance of it.
514 There is currently no mechanism to relate an interface declared within
515 a generic to the corresponding interface in an instance, so we must
516 traverse the list of interfaces of the actual, looking for a name
517 match, and verifying that that interface is declared in an instance.
519 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
521 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
522 assertions; replace function versions of Next_Formal/Next_Actual with
523 their procedural versions (which are more concise).

1753 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
1754 delegate the secondary stack management when there is no suitable
1755 transient context, and the transient scope was intended to manage the

1760 the comment on usage.
1761 (Find_Transient_Context): Change the initinte loop into a while loop.

2035 * gnat_rm.texi: Regenerate.
2037 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2039 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
2040 formsl type corresponding to the actual fixed point type is private,
2041 because in this case there can be no suspicious arithmetic operations
2042 in the generic unless they reference a formal subprogram. Clarify
2045 2018-01-11 Javier Miranda <miranda@adacore.com>
2047 * exp_util.adb (Remove_Side_Effects): No action done for functions
2048 returning class-wide types since it requires generating code using
2049 'reference and the CCG target has no secondary stack.
2050 * gnat1drv.adb: Disable building static dispatch tables when generating
2053 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
2055 * libgnat/a-direio.ads, libgnat/a-sequio.ads, libgnat/a-ststio.ads,
2056 libgnat/a-textio.ads, libgnat/a-witeio.ads, libgnat/a-ztexio.ads
2057 (File_Type): Add Default_Initial_Condition aspect.
2059 2018-01-11 Pascal Obry <obry@adacore.com>
2061 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
2063 2018-01-11 Bob Duff <duff@adacore.com>
2065 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
2066 to match what the Libadalang-based version does.
2067 * doc/gnat_ugn/about_this_guide.rst: Update reference.
2069 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2071 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
2072 if it contains at least one component declaration employing a function
2073 call returning on the secondary stack.
2075 2018-01-11 Yannick Moy <moy@adacore.com>
2077 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
2078 Update description of restriction SPARK_05 with SPARK 2014.

2085 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2087 * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
2088 sem_res.adb, sem_util.adb: Minor reformatting.
2090 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2092 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
2093 has a delayed aspect which must be processed at the point the type is
2094 frozen. This mimics what is done when the predicate is provided by a
2097 2018-01-11 Doug Rupp <rupp@adacore.com>
2099 * init.c (vxworks): Add macro checks for __aarch64__.
2101 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2103 * exp_util.adb (Add_Failure_Expression): New routine.
2104 (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
2105 * sem_util.adb (Is_Current_Instance): Code cleanup.
2107 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2109 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
2110 Default_Sec_Stack_Size.
2111 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
2112 limit check so that the integer index does not overflow. Check the
2113 dynamic stack allocation does not cause the secondary stack pointer to
2115 (SS_Info): Align colons.
2116 (SS_Init): Cover the case when bootstraping with an old compiler that
2117 does not set Default_SS_Size.
2119 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2121 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
2122 legality of an inherited operation that may require overriding, ignore
2123 primitive_wrappers that correspond to explicit operations that override
2124 an interface primitive.
2125 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2126 operation to which the class-wide expression applies is a protected op.
2127 with a primitive_wrapper, verify that the updated inherited expression
2128 does not contain an internal call to a protected function. This
2129 completes the implementation of AI12-0166.
2131 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2133 * ali.adb: Document the remaining letters available for ALI lines.
2134 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
2135 * ali.ads: Update type With_Record. Field
2136 Implicit_With_From_Instantiation is no longer in use. Add field
2138 * csinfo.adb (CSinfo): Remove the setup for attribute
2139 Implicit_With_From_Instantiation.
2140 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
2141 either implicitly or explicitly withed.
2142 (Is_Implicit_With_Clause): New routine.
2143 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2144 confusion with the with clause attribute by the same name.
2145 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
2146 * rtsfind.adb (Maybe_Add_With): Code cleanup.
2147 * sem_ch8.adb (Present_System_Aux): Code cleanup.
2148 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
2150 (Implicit_With_On_Parent): Mark the with clause as generated for a
2152 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
2153 instantiation are no longer marked as Implicit_With_From_Instantiation
2154 because they are already marked as implicit.
2155 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
2156 which marks implicit with clauses as related to an instantiation.
2157 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2158 (Parent_With): New routine.
2159 (Set_Implicit_With_From_Instantiation): Removed.
2160 (Set_Parent_With): New routine.
2161 * sinfo.ads: Update the documentation of attribute Implicit_With.
2162 Remove attribute Implicit_With_From_Instantiation along with
2163 occurrences in nodes. Add attribute Parent_With along with occurrences
2165 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
2166 (Parent_With): New routine along with pragma Inline.
2167 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
2168 (Set_Parent_With): New routine along with pragma Inline.
2170 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2172 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
2173 entity when the enclosing construct is a body.
2175 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2177 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2178 Secondary_Stack_Size handling as a pragma is now generated for the
2179 corresponding aspect instead of an attribute. Pragma expression is
2180 relocated instead of evaluated. Discriminant of the corresponding
2181 record type is referenced rather than the type discriminant.
2182 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2183 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2184 * sem_ch13.adb (Analyze_One_Aspect): Transform
2185 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2186 because the attribute does not have visibility on a task type's
2187 discriminants when the type's definition is expanded.
2188 (Analyze_Attribute_Definition_Clause): Remove handling of
2189 Attribute_Secondary_Stack_Size.
2190 * snames.adb-tmpl, snames.ads-tmpl: Remove
2191 Attribute_Secondary_Stack_Size, no longer used.
2193 2018-01-11 Justin Squirek <squirek@adacore.com>
2195 * sem_ch8.adb: Minor comment fix.
2197 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2199 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
2200 individual action because the action may denote a complex expression,
2201 such as a case statement, which in turn may contain additional
2204 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2206 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2207 analysis on a copy of the expression with a copy of the index variable,
2208 because full expansion will rewrite construct into a loop with the
2209 original loop variable.
2210 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2211 expression is an iterated component association. Full analysis takes
2212 place when construct is rewritten as a loop.
2213 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2214 is not safe for in-place assignment.
2215 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2216 entity with no homonym and no other entity in the scope.
2218 2018-01-11 Justin Squirek <squirek@adacore.com>
2220 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
2221 message to be printed on the pragma argument identifier.
2223 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2225 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
2226 entity of the generated invariant procedure in order to construct a
2227 proper entity chain.
2229 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
2231 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
2234 2018-01-11 Arnaud Charlet <charlet@adacore.com>
2236 * einfo.ads, einfo.adb (Activation_Record_Component,
2237 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
2238 Allow E_Discriminant.
2240 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
2242 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
2243 for atomic access once the component size is taken into account and
2244 also do it if the component type is Atomic or Volatile_Full_Access.
2246 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
2248 * gnatvsn.ads: Bump copyright year.

2265 Alan Hayward <alan.hayward@arm.com>
2266 David Sherwood <david.sherwood@arm.com>
2268 * gcc-interface/utils.c (gnat_types_compatible_p): Handle
2269 polynomial TYPE_VECTOR_SUBPARTS.
