19 2018-05-29 Javier Miranda <miranda@adacore.com>
21 * exp_ch4.adb (Expand_N_Op_Eq, Expand_Composite_Equality): Use the new
22 subprogram Inherits_From_Tagged_Full_View to identify more reliably
23 untagged private types completed with a derivation of an untagged
24 private whose full view is a tagged type.
25 * sem_util.ads, sem_util.adb (Inherits_From_Tagged_Full_View): New
27 (Collect_Primitive_Operations): Handle untagged private types completed
28 with a derivation of an untagged private type whose full view is a
29 tagged type. In such case, collecting the list of primitives we may
30 find two equality primitives: one associated with the untagged private
31 and another associated with the ultimate tagged type (and we must
32 remove from the returned list this latter one).

69 carry no type. Such selected components appear in unit names that are
70 child units, both in the specification and possibly in an end label for
71 the unit, and they do not contain any relevant uplevel references.

89 2018-05-29 Olivier Hainque <hainque@adacore.com>
91 * vx_crtbegin.inc: Use a consistent naming convention for the
92 registration/deregistration functions across RTP or kernel. Remove the
93 ctor/dtor attribute setting based on RTP/kernel, expect the optional

265 references, examine index expressions or associated expressions as well
266 to record uplevel references.

268 unconstrained array and the actual is constrained, check whether bounds
269 of actual have uplevel references.
271 2018-05-28 Ed Schonberg <schonberg@adacore.com>
273 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
274 they can appear as components of activation records.

278 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>

281 depends on a discriminant manually instead of using the predicate
282 Size_Depends_On_Discriminant in the array type case.

293 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
294 value when converting a float value to a fixed-point value. This is
295 required for CCG because it handles fixed-point types by means of
296 unsigned integer type variables. The range check is now performed using
297 the integer value stored in this temporary.
299 2018-05-28 Yannick Moy <moy@adacore.com>
301 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and
302 Length as valid non-interfering contexts for SPARK.
304 2018-05-28 Claire Dross <dross@adacore.com>
306 * sem_disp.ads, sem_disp.adb (Inheritance_Utilities): Package for
307 generic inheritance utilities.
308 (Generic_Inherited_Subprograms): Generic version of
309 Inherited_Subprograms, generic in Find_Dispatching_Type function.
310 (Generic_Is_Overriding_Subprogram): Generic version of
311 Is_Overriding_Subprogram, generic in Find_Dispatching_Type function.

321 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
322 component type, do not expand array equality using the unconstrained
323 base type, except for the case where the bounds of the type depend on a
326 2018-05-28 Ed Schonberg <schonberg@adacore.com>
328 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
329 access-to-subprogram types, to indicate that an indirect call through
330 such a type requires an activation record when compiling for LLVM.
331 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
333 2018-05-28 Ed Schonberg <schonberg@adacore.com>
335 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
336 when bounds of fixed type are static, to remove some spuerfluous
337 implicit conversions and provide an accurate result when converting
338 back and forth between the fixed point type and a floating point type.
340 2018-05-28 Ed Schonberg <schonberg@adacore.com>
342 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
345 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
347 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
348 replaced, if any; all callers changed.
349 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
350 constant with private view so we take the address of that entity.
351 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
352 any; all callers changed. Handle N_Indexed_Component like
353 N_Attribute_Reference. Add N_Type_Conversion case.
354 (Visit_Node): Indexed references can be uplevel if the type isn't
356 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
357 been relocated, set first_named pointer in original node as well.
359 2018-05-28 Ed Schonberg <schonberg@adacore.com>
361 * exp_aggr.adb (Flatten): Copy tree of expression in a component
362 association with a range or a set of discrete choices, rather than
363 relocating the node. This avoids inconsistencies in the tree when
364 handling nested subprograms with uplevel references for LLVM.
366 2018-05-28 Arnaud Charlet <charlet@adacore.com>

378 unnecessary use of 'Unrestricted_Access.

419 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
420 the declarations of single concurrent types because they fall in the
421 category of full type and object declarations.

430 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
431 includes a call to function to which it applies. This may mean an
432 omission of an attribute reference 'Result, in particular if the
433 function is pqrameterless.
435 2018-05-28 Justin Squirek <squirek@adacore.com>
437 * sem_ch8.adb (Find_Expanded_Name): Add extra guard to make sure the

449 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
450 end with the linker section, if any.
451 (List_Entities): Do not output the linker section for record types,
452 array types and variables.
453 (Print_Expr): Factor out common processing for unary operators and
454 special values. Adjust and reorder the various cases.
455 (List_Object_Info): End with the linker section, if any.
456 (List_Record_Info): Likewise.

461 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
462 that the result will be either -infinite or +infinite.
464 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
466 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,
467 libgnat/s-parame__ae653.ads, libgnat/s-parame__hpux.ads (Size_Type):
468 Expand range of type to match the address space of the target.
469 (Task_Storage_Size): Remove unused type.
471 2018-05-25 Ed Schonberg <schonberg@adacore.com>
473 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
474 of a fixed point type and the parent is a multiplying operation,
475 resolve the operand with its own type because the context will impose a
476 resulting type on the result of the multiplication by means of
477 approriate conversion.
479 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
481 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
482 the in-place initialization aggregate created for pragmas
483 Initialize_Scalars or Normalize_Scalars is performed with checks
486 2018-05-25 Arnaud Charlet <charlet@adacore.com>
488 * exp_aggr.adb (Convert_To_Positional): Bump default for
489 Max_Others_Replicate to 32. Update comments.
490 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
491 (No_File_Info_Cache): Initialize separately.
492 * osint.adb (No_File_Info_Cache): Update initializer.

510 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
512 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
513 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
514 into three distring cases rather than in one loop which attempts to
515 handle all three cases. This rewrite eliminates an issue where the last
516 frame of the stack cannot be freed, thus causing the memory range of a
517 new frame to approach the overflow point of the memory index type.
518 Since the overflow is logically treated as a
519 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
520 (SS_Allocate_Static): New routine. The routine factorizes the static
521 secondary stack-related code from the former SS_Allocate.
523 2018-05-25 Sergey Rybin <rybin@adacore.com>

574 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
575 Validate_Derived_Type_Instance, to verify that all interfaces
576 implemented by the formal type are also implemented by the actual. The

579 There is currently no mechanism to relate an interface declared within
580 a generic to the corresponding interface in an instance, so we must
581 traverse the list of interfaces of the actual, looking for a name
582 match, and verifying that that interface is declared in an instance.

2031 (Expand_Array_Aggregate): Update the call to Establish_Transient_Scope.
2032 * exp_ch6.adb (Expand_Call_Helper): Update the call to
2033 Establish_Transient_Scope.
2034 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
2035 Establish_Transient_Scope.
2036 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
2037 management of the secondary stack to an enclosing scope if there is no
2038 suitable construct to wrap, and the transient scope was intended to
2039 manage the secondary stack.
2040 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
2041 is a valid boundary for a transient expression which comes from the
2042 statements of the alternative, otherwise alternatives cannot be
2043 wrapped. Assignments of controlled objects which have controlled
2044 actions suppressed now stop the traversal as there is no point in
2045 looking for an enclosing construct. Add several N_xxx_Body choices to
2046 the termination conditions for completeness.
2047 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
2048 and the associated comment on usage.
2049 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
2050 Establish_Transient_Scope.
2051 (Add_Write_After): Update the call to Establish_Transient_Scope.
2052 * sem_res.adb (Check_Initialization_Call): Removed.
2053 (Resolve_Actuals): Account for additional cases where finalization
2054 actions are required by utilizing predicate Needs_Finalization rather
2056 (Resolve_Call): Type initialization procedures can now utilize
2057 transient scopes to manage the secondary stack, thus preventing leaks
2058 during initialization. Remove the previous kludgy algorithm which
2059 attempts to manage the secondary stack at the object creation site.
2061 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
2063 * libgnat/g-soliop__qnx.ads: New.

2100 * gnat_rm.texi: Regenerate.
2102 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2104 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
2105 formsl type corresponding to the actual fixed point type is private,
2106 because in this case there can be no suspicious arithmetic operations
2107 in the generic unless they reference a formal subprogram. Clarify
2110 2018-01-11 Javier Miranda <miranda@adacore.com>
2112 * exp_util.adb (Remove_Side_Effects): No action done for functions
2113 returning class-wide types since it requires generating code using
2114 'reference and the CCG target has no secondary stack.
2115 * gnat1drv.adb: Disable building static dispatch tables when generating
2118 2018-01-11 Piotr Trojanek <trojanek@adacore.com>

2122 (File_Type): Add Default_Initial_Condition aspect.
2124 2018-01-11 Pascal Obry <obry@adacore.com>
2126 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
2128 2018-01-11 Bob Duff <duff@adacore.com>
2130 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
2131 to match what the Libadalang-based version does.
2132 * doc/gnat_ugn/about_this_guide.rst: Update reference.
2134 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2136 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
2137 if it contains at least one component declaration employing a function
2138 call returning on the secondary stack.
2140 2018-01-11 Yannick Moy <moy@adacore.com>
2142 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
2143 Update description of restriction SPARK_05 with SPARK 2014.

2152 * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
2153 sem_res.adb, sem_util.adb: Minor reformatting.
2155 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2157 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
2158 has a delayed aspect which must be processed at the point the type is
2159 frozen. This mimics what is done when the predicate is provided by a
2162 2018-01-11 Doug Rupp <rupp@adacore.com>
2164 * init.c (vxworks): Add macro checks for __aarch64__.
2166 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2168 * exp_util.adb (Add_Failure_Expression): New routine.

2170 * sem_util.adb (Is_Current_Instance): Code cleanup.
2172 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2174 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
2175 Default_Sec_Stack_Size.
2176 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
2177 limit check so that the integer index does not overflow. Check the
2178 dynamic stack allocation does not cause the secondary stack pointer to
2180 (SS_Info): Align colons.
2181 (SS_Init): Cover the case when bootstraping with an old compiler that
2182 does not set Default_SS_Size.
2184 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2186 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
2187 legality of an inherited operation that may require overriding, ignore
2188 primitive_wrappers that correspond to explicit operations that override
2189 an interface primitive.
2190 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2191 operation to which the class-wide expression applies is a protected op.
2192 with a primitive_wrapper, verify that the updated inherited expression
2193 does not contain an internal call to a protected function. This
2194 completes the implementation of AI12-0166.
2196 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2198 * ali.adb: Document the remaining letters available for ALI lines.
2199 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
2200 * ali.ads: Update type With_Record. Field
2201 Implicit_With_From_Instantiation is no longer in use. Add field
2203 * csinfo.adb (CSinfo): Remove the setup for attribute
2204 Implicit_With_From_Instantiation.
2205 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
2206 either implicitly or explicitly withed.
2207 (Is_Implicit_With_Clause): New routine.
2208 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2209 confusion with the with clause attribute by the same name.
2210 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
2211 * rtsfind.adb (Maybe_Add_With): Code cleanup.
2212 * sem_ch8.adb (Present_System_Aux): Code cleanup.
2213 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
2215 (Implicit_With_On_Parent): Mark the with clause as generated for a
2217 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
2218 instantiation are no longer marked as Implicit_With_From_Instantiation
2219 because they are already marked as implicit.
2220 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
2221 which marks implicit with clauses as related to an instantiation.
2222 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2223 (Parent_With): New routine.
2224 (Set_Implicit_With_From_Instantiation): Removed.
2225 (Set_Parent_With): New routine.
2226 * sinfo.ads: Update the documentation of attribute Implicit_With.
2227 Remove attribute Implicit_With_From_Instantiation along with
2228 occurrences in nodes. Add attribute Parent_With along with occurrences

2231 (Parent_With): New routine along with pragma Inline.
2232 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
2233 (Set_Parent_With): New routine along with pragma Inline.
2235 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2237 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
2238 entity when the enclosing construct is a body.
2240 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2242 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2243 Secondary_Stack_Size handling as a pragma is now generated for the
2244 corresponding aspect instead of an attribute. Pragma expression is
2245 relocated instead of evaluated. Discriminant of the corresponding
2246 record type is referenced rather than the type discriminant.
2247 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2248 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2249 * sem_ch13.adb (Analyze_One_Aspect): Transform
2250 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2251 because the attribute does not have visibility on a task type's
2252 discriminants when the type's definition is expanded.
2253 (Analyze_Attribute_Definition_Clause): Remove handling of
2254 Attribute_Secondary_Stack_Size.
2255 * snames.adb-tmpl, snames.ads-tmpl: Remove
2256 Attribute_Secondary_Stack_Size, no longer used.
2258 2018-01-11 Justin Squirek <squirek@adacore.com>

2262 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2264 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
2265 individual action because the action may denote a complex expression,
2266 such as a case statement, which in turn may contain additional
2269 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2271 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2272 analysis on a copy of the expression with a copy of the index variable,
2273 because full expansion will rewrite construct into a loop with the
2274 original loop variable.
2275 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2276 expression is an iterated component association. Full analysis takes
2277 place when construct is rewritten as a loop.
2278 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2279 is not safe for in-place assignment.
2280 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2281 entity with no homonym and no other entity in the scope.
2283 2018-01-11 Justin Squirek <squirek@adacore.com>
2285 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
2286 message to be printed on the pragma argument identifier.
2288 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2290 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
2291 entity of the generated invariant procedure in order to construct a
2292 proper entity chain.
2294 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
2296 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
2299 2018-01-11 Arnaud Charlet <charlet@adacore.com>
2301 * einfo.ads, einfo.adb (Activation_Record_Component,
2302 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
2303 Allow E_Discriminant.
2305 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
2307 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
2308 for atomic access once the component size is taken into account and
2309 also do it if the component type is Atomic or Volatile_Full_Access.
2311 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
2313 * gnatvsn.ads: Bump copyright year.
