19 component type, do not expand array equality using the unconstrained
20 base type, except for the case where the bounds of the type depend on a
23 2018-05-28 Ed Schonberg <schonberg@adacore.com>
25 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
26 access-to-subprogram types, to indicate that an indirect call through
27 such a type requires an activation record when compiling for LLVM.
28 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
30 2018-05-28 Ed Schonberg <schonberg@adacore.com>
32 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
33 when bounds of fixed type are static, to remove some spuerfluous
34 implicit conversions and provide an accurate result when converting
35 back and forth between the fixed point type and a floating point type.
37 2018-05-28 Ed Schonberg <schonberg@adacore.com>
39 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty

49 any; all callers changed. Handle N_Indexed_Component like
50 N_Attribute_Reference. Add N_Type_Conversion case.

58 * exp_aggr.adb (Flatten): Copy tree of expression in a component
59 association with a range or a set of discrete choices, rather than
60 relocating the node. This avoids inconsistencies in the tree when
61 handling nested subprograms with uplevel references for LLVM.
63 2018-05-28 Arnaud Charlet <charlet@adacore.com>
65 * exp_util.adb (Possible_Bit_Aligned_Component): Always return False in

72 2018-05-28 Bob Duff <duff@adacore.com>
74 * libgnat/a-convec.adb (Query_Element): Minor cleanup: remove an
75 unnecessary use of 'Unrestricted_Access.
77 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
79 * repinfo.adb (Expr_Value_S): New routine.

114 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
116 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
117 the declarations of single concurrent types because they fall in the

127 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
128 includes a call to function to which it applies. This may mean an
129 omission of an attribute reference 'Result, in particular if the
130 function is pqrameterless.
132 2018-05-28 Justin Squirek <squirek@adacore.com>
134 * sem_ch8.adb (Find_Expanded_Name): Add extra guard to make sure the
135 misresolved package name is not a case of mistaken identity.

139 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
140 GNATprove mode, as the order of resolution (low then high) means that
141 all the information is not available when resolving the low bound the
144 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
146 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
147 end with the linker section, if any.
148 (List_Entities): Do not output the linker section for record types,
149 array types and variables.
150 (Print_Expr): Factor out common processing for unary operators and
151 special values. Adjust and reorder the various cases.

165 Expand range of type to match the address space of the target.
166 (Task_Storage_Size): Remove unused type.
168 2018-05-25 Ed Schonberg <schonberg@adacore.com>
170 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
171 of a fixed point type and the parent is a multiplying operation,
172 resolve the operand with its own type because the context will impose a
173 resulting type on the result of the multiplication by means of
174 approriate conversion.
176 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
178 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
179 the in-place initialization aggregate created for pragmas
180 Initialize_Scalars or Normalize_Scalars is performed with checks
183 2018-05-25 Arnaud Charlet <charlet@adacore.com>
185 * exp_aggr.adb (Convert_To_Positional): Bump default for

209 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
210 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
211 into three distring cases rather than in one loop which attempts to
212 handle all three cases. This rewrite eliminates an issue where the last
213 frame of the stack cannot be freed, thus causing the memory range of a
214 new frame to approach the overflow point of the memory index type.
215 Since the overflow is logically treated as a
216 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
217 (SS_Allocate_Static): New routine. The routine factorizes the static
218 secondary stack-related code from the former SS_Allocate.
220 2018-05-25 Sergey Rybin <rybin@adacore.com>

227 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
228 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
229 is created when the proper body of the stub is analyzed.
230 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
231 is the proper body of a subunit, the cloned body must be inserted in
232 the declarative list that contains the stub.
234 2018-05-25 Justin Squirek <squirek@adacore.com>
236 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
237 generate code for 6.5(8-10) so that we don't get an assertion error
238 when dealing with an incomplete return type.
240 2018-05-25 Arnaud Charlet <charlet@adacore.com>
242 * pprint.adb (Expression_Name): Strip too long expressions to avoid
243 carrying very large strings.

269 2018-05-25 Ed Schonberg <schonberg@adacore.com>
271 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
272 Validate_Derived_Type_Instance, to verify that all interfaces
273 implemented by the formal type are also implemented by the actual. The
274 verification is complicated when an interface of the formal is declared
275 in a generic unit and the actual is declared in an instance of it.
276 There is currently no mechanism to relate an interface declared within
277 a generic to the corresponding interface in an instance, so we must
278 traverse the list of interfaces of the actual, looking for a name
279 match, and verifying that that interface is declared in an instance.
281 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
283 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
284 assertions; replace function versions of Next_Formal/Next_Actual with
285 their procedural versions (which are more concise).

354 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
355 declaration is inserted into the tree and analyzed at that point, so
356 should not be reinserted when the body is constructed. Inside a
357 generic, ensure that the body is not inserted twice in the tree.
359 2018-05-25 Yannick Moy <moy@adacore.com>
361 * sem_prag.adb (Check_Grouping): Modify test to ignore statements and
362 declarations not coming from source.

395 body of a variant record equality renaming.
396 (Expand_N_Subprogram_Renaming_Declaration): Adapt the code to the new
397 implementation of Build_Body_For_Renaming.
398 * exp_ch3.ads (Build_Variant_Record_Equality): New library level
399 function that factorizes the functionality needed by
400 Build_Body_For_Renaming and Expand_Freeze_Record_Type to build the body
401 of a variant record equality subprogram.
402 * exp_ch3.adb (Build_Variant_Record_Equality): New subprogram.

1735 suitable construct to wrap, and the transient scope was intended to
1736 manage the secondary stack.
1737 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
1738 is a valid boundary for a transient expression which comes from the
1739 statements of the alternative, otherwise alternatives cannot be
1740 wrapped. Assignments of controlled objects which have controlled
1741 actions suppressed now stop the traversal as there is no point in
1742 looking for an enclosing construct. Add several N_xxx_Body choices to

1750 (Resolve_Actuals): Account for additional cases where finalization
1751 actions are required by utilizing predicate Needs_Finalization rather
1753 (Resolve_Call): Type initialization procedures can now utilize
1754 transient scopes to manage the secondary stack, thus preventing leaks
1755 during initialization. Remove the previous kludgy algorithm which
1756 attempts to manage the secondary stack at the object creation site.

1885 primitive_wrappers that correspond to explicit operations that override
1886 an interface primitive.
1887 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
1888 operation to which the class-wide expression applies is a protected op.
1889 with a primitive_wrapper, verify that the updated inherited expression
1890 does not contain an internal call to a protected function. This
1891 completes the implementation of AI12-0166.

1903 either implicitly or explicitly withed.
1904 (Is_Implicit_With_Clause): New routine.
1905 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
1906 confusion with the with clause attribute by the same name.

1918 which marks implicit with clauses as related to an instantiation.
1919 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
1920 (Parent_With): New routine.
1921 (Set_Implicit_With_From_Instantiation): Removed.

1939 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
1940 Secondary_Stack_Size handling as a pragma is now generated for the
1941 corresponding aspect instead of an attribute. Pragma expression is
1942 relocated instead of evaluated. Discriminant of the corresponding
1943 record type is referenced rather than the type discriminant.
1944 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
1945 Secondary_Stack_Size rep item checks to only look for the pragma rep.
1946 * sem_ch13.adb (Analyze_One_Aspect): Transform
1947 Aspect_Secondary_Stack_Size into a pragma instead of an attribute

1968 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
1969 analysis on a copy of the expression with a copy of the index variable,
1970 because full expansion will rewrite construct into a loop with the
1971 original loop variable.
1972 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
1973 expression is an iterated component association. Full analysis takes
1974 place when construct is rewritten as a loop.
1975 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
1976 is not safe for in-place assignment.
