314 Refine the handling of freezing types for expression functions
315 that are not completions, when analyzing the generated body for
316 the function: the body is inserted at the end of the enclosing

318 the same scope that have not been frozen yet.
320 2018-08-21 Ed Schonberg <schonberg@adacore.com>
322 * sem_ch6.adb: Remove Freeze_Expr_Types.

344 2018-08-21 Ed Schonberg <schonberg@adacore.com>
346 * sem_ch6.adb (Check_Synchronized_Overriding): The conformance
347 between an overriding protected operation and the overridden
348 abstract progenitor operation requires subtype conformance;
349 requiring equality of return types in the case of a function is
350 too restrictive and leads to spurious errors when the return
351 type is a generic actual.
353 2018-08-21 Ed Schonberg <schonberg@adacore.com>

377 parameters depending on their modes then analyse the body
379 (Check_Declaration): Consider both deep (including elementary
380 access) object declarations and normal variables. First check
381 whether the deep object is of Ownership Aspec True or not, then,
382 depending on its initialization, assign the appropriate state.
383 Check related to non access type variables deal with
384 initialization value permissions.

405 one expected (in the statement being analyzed).
406 (Process_Path): Given an operation and a current state, call
407 Perm_Error if there is any mismatch.
408 (Return_Declarations, Return_Globals, Return_The_Global): Check
409 the state of a given name at the end of the subprogram. These
410 procedures may change depending on how we shall finally deal
411 with globals and the rhs state in a move operation.
412 (Set_Perm_Extensions, Set_Perm_Prefixes_Borrow,
413 Set_Perm_Prefixes, Setup_Globals, Setup_Parameter_Or_Global,
414 Setup_Parameters): Set up the new states to the given node and

753 * sem_ch4.adb (Try_Object_Operation): Handle properly a prefixed call
754 in an instance, when the generic parameters include an interface type
755 and a abstract operation of that type, and the actuals in the instance

921 we continued freezeing entities outside of the subprogram. Now, when
922 climbing the parents chain to locate the correct placement for the
923 freezeing node, we check if the entity can be frozen and only when no

936 Its code is basically the previous version of this routine but extended
937 with an additional parameter which is used to specify if during
938 preanalysis we are allowed to freeze entities. If the new parameter is
939 True then the subtree root node is marked as Must_Not_Freeze and no
940 entities are frozen during preanalysis.
941 (Preanalyze_And_Resolve): Invokes the internal version of
942 Preanalyze_And_Resolve without entity freezing.
943 (Preanalyze_With_Freezing_And_Resolve): Invokes the internal version of

978 enclosing scope already handles the secondary stack, take into account
979 transient blocks nested in a block that do not manage the secondary
980 stack and are located within a loop.
982 2018-07-17 Ed Schonberg <schonberg@adacore.com>
984 * sem_util.adb (Enclosing_Subprogram): Protected entries and task
985 entries must be treated separately: task entries are within the

1864 * exp_ch4.adb (Expand_Modular_Addition, Expand_Modular_Subtraction):
1865 Convert all operands of the generated code to Standard.Unsigned, to
1866 prevent spurious visibility errors. This is needed when the generated

2007 2018-05-30 Bob Duff <duff@adacore.com>
2009 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
2010 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
2011 We need to analyze it as part of analyzing the block, so that if the
2012 call to Element that initializes Elmt_Decl returns on the secondary
2013 stack, the block will ss_mark/ss_release. This block is inside the
2014 loop; we don't want to leak memory until the loop exits. The purpose
2015 of analyzing Elmt_Decl first was to catch the error of modifying it,
2016 which is illegal because it's a loop parameter. The above causes us to
2017 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
2018 it on the Element entity, so we end up with an E_Variable node with the
2020 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
2021 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
2022 parameter not allowed" error if Is_Loop_Parameter.
2023 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to

2038 2018-05-30 Ed Schonberg <schonberg@adacore.com>
2040 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
2041 a package body that is a compilation unit may contain blocks that
2042 declare local subprograms. In Subprogram_Unnesting Mode such
2043 subprograms must be handled as nested inside the (implicit) elaboration
2044 procedure that executes that statement part. To handle properly uplevel
2045 references we construct that subprogram explicitly, to contain blocks
2046 and inner subprograms, The statement part of the compilation unit
2047 becomes a call to this subprogram. This is only done if blocks are
2048 present in the statement list of the body.

2112 subprogram Inherits_From_Tagged_Full_View to identify more reliably
2113 untagged private types completed with a derivation of an untagged
2114 private whose full view is a tagged type.

2117 (Collect_Primitive_Operations): Handle untagged private types completed
2118 with a derivation of an untagged private type whose full view is a
2119 tagged type. In such case, collecting the list of primitives we may
2120 find two equality primitives: one associated with the untagged private

2359 of actual have uplevel references.
2361 2018-05-28 Ed Schonberg <schonberg@adacore.com>

2381 2018-05-28 Javier Miranda <miranda@adacore.com>
2383 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
2384 value when converting a float value to a fixed-point value. This is
2385 required for CCG because it handles fixed-point types by means of

2387 the integer value stored in this temporary.
2389 2018-05-28 Yannick Moy <moy@adacore.com>

2418 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
2419 access-to-subprogram types, to indicate that an indirect call through

2423 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2425 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
2426 when bounds of fixed type are static, to remove some spuerfluous
2427 implicit conversions and provide an accurate result when converting
2428 back and forth between the fixed point type and a floating point type.

2437 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
2438 replaced, if any; all callers changed.
2439 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
2440 constant with private view so we take the address of that entity.
2441 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
2442 any; all callers changed. Handle N_Indexed_Component like
2443 N_Attribute_Reference. Add N_Type_Conversion case.
2444 (Visit_Node): Indexed references can be uplevel if the type isn't
2446 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
2447 been relocated, set first_named pointer in original node as well.

2451 * exp_aggr.adb (Flatten): Copy tree of expression in a component
2452 association with a range or a set of discrete choices, rather than
2453 relocating the node. This avoids inconsistencies in the tree when
2454 handling nested subprograms with uplevel references for LLVM.

2563 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
2564 of a fixed point type and the parent is a multiplying operation,
2565 resolve the operand with its own type because the context will impose a
2566 resulting type on the result of the multiplication by means of
2567 approriate conversion.

2600 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2602 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
2603 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
2604 into three distring cases rather than in one loop which attempts to
2605 handle all three cases. This rewrite eliminates an issue where the last
2606 frame of the stack cannot be freed, thus causing the memory range of a
2607 new frame to approach the overflow point of the memory index type.
2608 Since the overflow is logically treated as a
2609 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
2610 (SS_Allocate_Static): New routine. The routine factorizes the static
2611 secondary stack-related code from the former SS_Allocate.

2623 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
2624 is the proper body of a subunit, the cloned body must be inserted in
2625 the declarative list that contains the stub.

2664 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
2665 Validate_Derived_Type_Instance, to verify that all interfaces
2666 implemented by the formal type are also implemented by the actual. The
2667 verification is complicated when an interface of the formal is declared
2668 in a generic unit and the actual is declared in an instance of it.
2669 There is currently no mechanism to relate an interface declared within
2670 a generic to the corresponding interface in an instance, so we must
2671 traverse the list of interfaces of the actual, looking for a name
2672 match, and verifying that that interface is declared in an instance.

3908 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
3909 delegate the secondary stack management when there is no suitable
3910 transient context, and the transient scope was intended to manage the

4065 * ghost.adb (Check_Ghost_Type): New routine.
4066 * ghost.ads (Check_Ghost_Type): New routine.
4067 * sem_util.adb (Is_Declaration): Reimplemented. The routine can now
4068 consider specific subsets of declarations.
4069 (Is_Declaration_Other_Than_Renaming): Removed. Its functionality is
4070 replicated by Is_Declaration.
4071 * sem_util.ads (Is_Declaration): New parameter profile. Update the
4073 (Is_Declaration_Other_Than_Renaming): Removed.
4075 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4077 * sem_ch5.adb (Analyze_Assignment): Assignments to variables that act
4078 as Part_Of consituents of single protected types are illegal when they
4079 take place inside a protected function.
4080 (Diagnose_Non_Variable_Lhs): Use Within_Function to check for an
4082 (Is_Protected_Part_Of_Constituent): New routine.
4083 (Within_Function): New routine.

4087 Bump copyright notices to 2018.
4089 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4091 * binde.adb, par-ch6.adb, par-ch9.adb, sem_ch12.adb, sem_ch13.adb:
4094 2018-01-11 Justin Squirek <squirek@adacore.com>
4096 * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
4097 to make sure a given expression function is properly parenthesized.
4099 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4101 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Check the
4102 categorization of a subprogram body which does not complete a previous
4105 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4107 * sem_ch10.adb (Check_Private_Child_Unit): Ensure that the enclosing
4108 scope of package Ada is Standard.
4110 2018-01-11 Ed Schonberg <schonberg@adacore.com>
4112 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
4113 subcomponent of the current entity when building the body for a dynamic
4114 predicate function for a record with composite subcomponents.
4116 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4118 * exp_aggr.adb (Convert_Aggr_In_Object_Decl): Update the call to
4119 Establish_Transient_Scope.

4124 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
4125 Establish_Transient_Scope.
4126 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
4127 management of the secondary stack to an enclosing scope if there is no
4128 suitable construct to wrap, and the transient scope was intended to
4129 manage the secondary stack.
4130 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
4131 is a valid boundary for a transient expression which comes from the
4132 statements of the alternative, otherwise alternatives cannot be
4133 wrapped. Assignments of controlled objects which have controlled
4134 actions suppressed now stop the traversal as there is no point in
4135 looking for an enclosing construct. Add several N_xxx_Body choices to
4136 the termination conditions for completeness.
4137 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
4138 and the associated comment on usage.
4139 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
4140 Establish_Transient_Scope.
4141 (Add_Write_After): Update the call to Establish_Transient_Scope.
4142 * sem_res.adb (Check_Initialization_Call): Removed.
4143 (Resolve_Actuals): Account for additional cases where finalization
4144 actions are required by utilizing predicate Needs_Finalization rather
4146 (Resolve_Call): Type initialization procedures can now utilize
4147 transient scopes to manage the secondary stack, thus preventing leaks
4148 during initialization. Remove the previous kludgy algorithm which
4149 attempts to manage the secondary stack at the object creation site.
4151 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
4153 * libgnat/g-soliop__qnx.ads: New.

4190 * gnat_rm.texi: Regenerate.
4192 2018-01-11 Ed Schonberg <schonberg@adacore.com>
4194 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
4195 formsl type corresponding to the actual fixed point type is private,
4196 because in this case there can be no suspicious arithmetic operations
4197 in the generic unless they reference a formal subprogram. Clarify
4200 2018-01-11 Javier Miranda <miranda@adacore.com>
4202 * exp_util.adb (Remove_Side_Effects): No action done for functions
4203 returning class-wide types since it requires generating code using
4204 'reference and the CCG target has no secondary stack.
4205 * gnat1drv.adb: Disable building static dispatch tables when generating

4218 2018-01-11 Bob Duff <duff@adacore.com>
4220 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
4221 to match what the Libadalang-based version does.
4222 * doc/gnat_ugn/about_this_guide.rst: Update reference.
4224 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4226 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
4227 if it contains at least one component declaration employing a function
4228 call returning on the secondary stack.

4245 2018-01-11 Ed Schonberg <schonberg@adacore.com>
4247 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
4248 has a delayed aspect which must be processed at the point the type is
4249 frozen. This mimics what is done when the predicate is provided by a

4265 Default_Sec_Stack_Size.
4266 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
4267 limit check so that the integer index does not overflow. Check the
4268 dynamic stack allocation does not cause the secondary stack pointer to
4270 (SS_Info): Align colons.
4271 (SS_Init): Cover the case when bootstraping with an old compiler that
4272 does not set Default_SS_Size.
4274 2018-01-11 Ed Schonberg <schonberg@adacore.com>
4276 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
4277 legality of an inherited operation that may require overriding, ignore
4278 primitive_wrappers that correspond to explicit operations that override
4279 an interface primitive.
4280 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
4281 operation to which the class-wide expression applies is a protected op.
4282 with a primitive_wrapper, verify that the updated inherited expression
4283 does not contain an internal call to a protected function. This
4284 completes the implementation of AI12-0166.
4286 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4288 * ali.adb: Document the remaining letters available for ALI lines.
4289 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
4290 * ali.ads: Update type With_Record. Field
4291 Implicit_With_From_Instantiation is no longer in use. Add field
4293 * csinfo.adb (CSinfo): Remove the setup for attribute
4294 Implicit_With_From_Instantiation.
4295 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
4296 either implicitly or explicitly withed.
4297 (Is_Implicit_With_Clause): New routine.
4298 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
4299 confusion with the with clause attribute by the same name.
4300 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
4301 * rtsfind.adb (Maybe_Add_With): Code cleanup.
4302 * sem_ch8.adb (Present_System_Aux): Code cleanup.

4305 (Implicit_With_On_Parent): Mark the with clause as generated for a
4307 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
4308 instantiation are no longer marked as Implicit_With_From_Instantiation
4309 because they are already marked as implicit.
4310 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
4311 which marks implicit with clauses as related to an instantiation.
4312 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
4313 (Parent_With): New routine.
4314 (Set_Implicit_With_From_Instantiation): Removed.
4315 (Set_Parent_With): New routine.
4316 * sinfo.ads: Update the documentation of attribute Implicit_With.

4328 entity when the enclosing construct is a body.
4330 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
4332 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
4333 Secondary_Stack_Size handling as a pragma is now generated for the
4334 corresponding aspect instead of an attribute. Pragma expression is
4335 relocated instead of evaluated. Discriminant of the corresponding
4336 record type is referenced rather than the type discriminant.
4337 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
4338 Secondary_Stack_Size rep item checks to only look for the pragma rep.
4339 * sem_ch13.adb (Analyze_One_Aspect): Transform
4340 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
4341 because the attribute does not have visibility on a task type's

4343 (Analyze_Attribute_Definition_Clause): Remove handling of
4344 Attribute_Secondary_Stack_Size.
4345 * snames.adb-tmpl, snames.ads-tmpl: Remove
4346 Attribute_Secondary_Stack_Size, no longer used.

4354 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
4355 individual action because the action may denote a complex expression,
4356 such as a case statement, which in turn may contain additional
4359 2018-01-11 Ed Schonberg <schonberg@adacore.com>
4361 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
4362 analysis on a copy of the expression with a copy of the index variable,
4363 because full expansion will rewrite construct into a loop with the
4364 original loop variable.
4365 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
4366 expression is an iterated component association. Full analysis takes
4367 place when construct is rewritten as a loop.
4368 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
4369 is not safe for in-place assignment.
4370 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
4371 entity with no homonym and no other entity in the scope.
4373 2018-01-11 Justin Squirek <squirek@adacore.com>
4375 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
4376 message to be printed on the pragma argument identifier.
4378 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4380 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
4381 entity of the generated invariant procedure in order to construct a
4382 proper entity chain.

4391 * einfo.ads, einfo.adb (Activation_Record_Component,
4392 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
4393 Allow E_Discriminant.
4395 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
4397 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
4398 for atomic access once the component size is taken into account and
4399 also do it if the component type is Atomic or Volatile_Full_Access.
4401 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
