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

1013 * sem_ch6.adb (Check_Synchronized_Overriding): The conformance
1014 between an overriding protected operation and the overridden
1015 abstract progenitor operation requires subtype conformance;
1016 requiring equality of return types in the case of a function is

1072 one expected (in the statement being analyzed).
1073 (Process_Path): Given an operation and a current state, call
1074 Perm_Error if there is any mismatch.
1075 (Return_Declarations, Return_Globals, Return_The_Global): Check
1076 the state of a given name at the end of the subprogram. These
1077 procedures may change depending on how we shall finally deal
1078 with globals and the rhs state in a move operation.

1080 Set_Perm_Prefixes, Setup_Globals, Setup_Parameter_Or_Global,

2142 generated code. Generate a branch for the heap and pool cases where
2143 the object is not necessarity controlled.

2674 2018-05-30 Bob Duff <duff@adacore.com>
2676 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
2677 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
2678 We need to analyze it as part of analyzing the block, so that if the
2679 call to Element that initializes Elmt_Decl returns on the secondary
2680 stack, the block will ss_mark/ss_release. This block is inside the
2681 loop; we don't want to leak memory until the loop exits. The purpose
2682 of analyzing Elmt_Decl first was to catch the error of modifying it,
2683 which is illegal because it's a loop parameter. The above causes us to
2684 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
2685 it on the Element entity, so we end up with an E_Variable node with the

2708 a package body that is a compilation unit may contain blocks that
2709 declare local subprograms. In Subprogram_Unnesting Mode such
2710 subprograms must be handled as nested inside the (implicit) elaboration
2711 procedure that executes that statement part. To handle properly uplevel
2712 references we construct that subprogram explicitly, to contain blocks
2713 and inner subprograms, The statement part of the compilation unit
2714 becomes a call to this subprogram. This is only done if blocks are
2715 present in the statement list of the body.

3111 (Visit_Node): Indexed references can be uplevel if the type isn't
3113 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
3114 been relocated, set first_named pointer in original node as well.

3118 * exp_aggr.adb (Flatten): Copy tree of expression in a component
3119 association with a range or a set of discrete choices, rather than

3135 unnecessary use of 'Unrestricted_Access.
3137 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
3139 * repinfo.adb (Expr_Value_S): New routine.
3140 (List_Linker_Section): Properly extract the value of the section
3143 2018-05-28 Patrick Bernardi <bernardi@adacore.com>
3145 * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Update the
3146 description of the -D binder switch to reflect current usage.
3147 * gnat_ugn.texi: Regenerate.
3149 2018-05-28 Gary Dismukes <dismukes@adacore.com>

3174 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
3176 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
3177 the declarations of single concurrent types because they fall in the
3178 category of full type and object declarations.
3180 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>

3187 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
3188 includes a call to function to which it applies. This may mean an
3189 omission of an attribute reference 'Result, in particular if the
3190 function is pqrameterless.
3192 2018-05-28 Justin Squirek <squirek@adacore.com>

3206 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
3207 end with the linker section, if any.
3208 (List_Entities): Do not output the linker section for record types,
3209 array types and variables.
3210 (Print_Expr): Factor out common processing for unary operators and
3211 special values. Adjust and reorder the various cases.
3212 (List_Object_Info): End with the linker section, if any.
3213 (List_Record_Info): Likewise.
3214 (List_Type_Info): Do not start with a blank line.
3216 2018-05-25 Nicolas Roche <roche@adacore.com>
3218 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
3219 that the result will be either -infinite or +infinite.

3226 (Task_Storage_Size): Remove unused type.
3228 2018-05-25 Ed Schonberg <schonberg@adacore.com>
3230 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
3231 of a fixed point type and the parent is a multiplying operation,
3232 resolve the operand with its own type because the context will impose a
3233 resulting type on the result of the multiplication by means of
3234 approriate conversion.
3236 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
3238 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
3239 the in-place initialization aggregate created for pragmas
3240 Initialize_Scalars or Normalize_Scalars is performed with checks
3243 2018-05-25 Arnaud Charlet <charlet@adacore.com>
3245 * exp_aggr.adb (Convert_To_Positional): Bump default for
3246 Max_Others_Replicate to 32. Update comments.
3247 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.

3267 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
3269 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
3270 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
3271 into three distring cases rather than in one loop which attempts to
3272 handle all three cases. This rewrite eliminates an issue where the last
3273 frame of the stack cannot be freed, thus causing the memory range of a
3274 new frame to approach the overflow point of the memory index type.
3275 Since the overflow is logically treated as a
3276 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
3277 (SS_Allocate_Static): New routine. The routine factorizes the static
3278 secondary stack-related code from the former SS_Allocate.
3280 2018-05-25 Sergey Rybin <rybin@adacore.com>

3287 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
3288 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
3289 is created when the proper body of the stub is analyzed.
3290 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
3291 is the proper body of a subunit, the cloned body must be inserted in
3292 the declarative list that contains the stub.
3294 2018-05-25 Justin Squirek <squirek@adacore.com>
3296 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
3297 generate code for 6.5(8-10) so that we don't get an assertion error
3298 when dealing with an incomplete return type.
3300 2018-05-25 Arnaud Charlet <charlet@adacore.com>

3329 2018-05-25 Ed Schonberg <schonberg@adacore.com>
3331 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
3332 Validate_Derived_Type_Instance, to verify that all interfaces
3333 implemented by the formal type are also implemented by the actual. The
3334 verification is complicated when an interface of the formal is declared
3335 in a generic unit and the actual is declared in an instance of it.
3336 There is currently no mechanism to relate an interface declared within
3337 a generic to the corresponding interface in an instance, so we must
3338 traverse the list of interfaces of the actual, looking for a name
3339 match, and verifying that that interface is declared in an instance.
3341 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
3343 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
3344 assertions; replace function versions of Next_Formal/Next_Actual with

3386 <E_Record_Type>: Force the size of a storage unit on empty classes.
3387 * gcc-interface/utils.c (make_type_from_size) <BOOLEAN_TYPE>: Skip
3388 boolean types with precision 1 if the size is the expected one.

3410 in loops at the library level.
3412 2018-05-25 Ed Schonberg <schonberg@adacore.com>
3414 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
3415 declaration is inserted into the tree and analyzed at that point, so
3416 should not be reinserted when the body is constructed. Inside a
3417 generic, ensure that the body is not inserted twice in the tree.

3909 iteration of an Ada2012 loop is performed to determine the type of the

4576 delegate the secondary stack management when there is no suitable
4577 transient context, and the transient scope was intended to manage the

4795 suitable construct to wrap, and the transient scope was intended to
4796 manage the secondary stack.
4797 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
4798 is a valid boundary for a transient expression which comes from the
4799 statements of the alternative, otherwise alternatives cannot be
4800 wrapped. Assignments of controlled objects which have controlled
4801 actions suppressed now stop the traversal as there is no point in

4810 (Resolve_Actuals): Account for additional cases where finalization
4811 actions are required by utilizing predicate Needs_Finalization rather
4813 (Resolve_Call): Type initialization procedures can now utilize
4814 transient scopes to manage the secondary stack, thus preventing leaks
4815 during initialization. Remove the previous kludgy algorithm which
4816 attempts to manage the secondary stack at the object creation site.

4948 operation to which the class-wide expression applies is a protected op.
4949 with a primitive_wrapper, verify that the updated inherited expression
4950 does not contain an internal call to a protected function. This
4951 completes the implementation of AI12-0166.

4978 which marks implicit with clauses as related to an instantiation.
4979 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
4980 (Parent_With): New routine.

4999 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
5000 Secondary_Stack_Size handling as a pragma is now generated for the
5001 corresponding aspect instead of an attribute. Pragma expression is
5002 relocated instead of evaluated. Discriminant of the corresponding
5003 record type is referenced rather than the type discriminant.
5004 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
5005 Secondary_Stack_Size rep item checks to only look for the pragma rep.
5006 * sem_ch13.adb (Analyze_One_Aspect): Transform
5007 Aspect_Secondary_Stack_Size into a pragma instead of an attribute

5028 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
5029 analysis on a copy of the expression with a copy of the index variable,
5030 because full expansion will rewrite construct into a loop with the
5031 original loop variable.
5032 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
5033 expression is an iterated component association. Full analysis takes
5034 place when construct is rewritten as a loop.
5035 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
5036 is not safe for in-place assignment.
