27 * libgnat/s-casuti.ads, libgnat/s-casuti.adb (To_Upper, To_Lower,
28 To_Mixed): New functions.
29 * osint.adb: Cleanup: use Is_Directory_Separator, which correctly
30 allows both '\' and '/' on Windows.

58 * exp_unst.adb (Visit_Node): For indexed components and attribute
59 references, examine index expressions or associated expressions as well
60 to record uplevel references.
61 (Vist_Node): For function and procedure calls, if a formal is an
62 unconstrained array and the actual is constrained, check whether bounds
63 of actual have uplevel references.
65 2018-05-28 Ed Schonberg <schonberg@adacore.com>
67 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
68 they can appear as components of activation records.

87 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
88 value when converting a float value to a fixed-point value. This is
89 required for CCG because it handles fixed-point types by means of
90 unsigned integer type variables. The range check is now performed using
91 the integer value stored in this temporary.
93 2018-05-28 Yannick Moy <moy@adacore.com>
95 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and
96 Length as valid non-interfering contexts for SPARK.

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

125 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
127 2018-05-28 Ed Schonberg <schonberg@adacore.com>
129 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
130 when bounds of fixed type are static, to remove some spuerfluous
131 implicit conversions and provide an accurate result when converting
132 back and forth between the fixed point type and a floating point type.

139 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
141 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
142 replaced, if any; all callers changed.
143 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
144 constant with private view so we take the address of that entity.
145 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
146 any; all callers changed. Handle N_Indexed_Component like
147 N_Attribute_Reference. Add N_Type_Conversion case.
148 (Visit_Node): Indexed references can be uplevel if the type isn't
150 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
151 been relocated, set first_named pointer in original node as well.
153 2018-05-28 Ed Schonberg <schonberg@adacore.com>
155 * exp_aggr.adb (Flatten): Copy tree of expression in a component
156 association with a range or a set of discrete choices, rather than
157 relocating the node. This avoids inconsistencies in the tree when
158 handling nested subprograms with uplevel references for LLVM.

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

243 * repinfo.adb (List_Array_Info): Start with an explicit blank line and

245 (List_Entities): Do not output the linker section for record types,
246 array types and variables.
247 (Print_Expr): Factor out common processing for unary operators and
248 special values. Adjust and reorder the various cases.

265 2018-05-25 Ed Schonberg <schonberg@adacore.com>
267 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
268 of a fixed point type and the parent is a multiplying operation,
269 resolve the operand with its own type because the context will impose a
270 resulting type on the result of the multiplication by means of
271 approriate conversion.
273 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
275 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
276 the in-place initialization aggregate created for pragmas
277 Initialize_Scalars or Normalize_Scalars is performed with checks
280 2018-05-25 Arnaud Charlet <charlet@adacore.com>
282 * exp_aggr.adb (Convert_To_Positional): Bump default for
283 Max_Others_Replicate to 32. Update comments.
284 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.

306 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
307 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
308 into three distring cases rather than in one loop which attempts to
309 handle all three cases. This rewrite eliminates an issue where the last
310 frame of the stack cannot be freed, thus causing the memory range of a
311 new frame to approach the overflow point of the memory index type.
312 Since the overflow is logically treated as a
313 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
314 (SS_Allocate_Static): New routine. The routine factorizes the static
315 secondary stack-related code from the former SS_Allocate.
317 2018-05-25 Sergey Rybin <rybin@adacore.com>
319 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'

324 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
325 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
326 is created when the proper body of the stub is analyzed.
327 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
328 is the proper body of a subunit, the cloned body must be inserted in
329 the declarative list that contains the stub.
331 2018-05-25 Justin Squirek <squirek@adacore.com>
333 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
334 generate code for 6.5(8-10) so that we don't get an assertion error
335 when dealing with an incomplete return type.
337 2018-05-25 Arnaud Charlet <charlet@adacore.com>

366 2018-05-25 Ed Schonberg <schonberg@adacore.com>
368 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
369 Validate_Derived_Type_Instance, to verify that all interfaces
370 implemented by the formal type are also implemented by the actual. The
371 verification is complicated when an interface of the formal is declared
372 in a generic unit and the actual is declared in an instance of it.
373 There is currently no mechanism to relate an interface declared within
374 a generic to the corresponding interface in an instance, so we must
375 traverse the list of interfaces of the actual, looking for a name
376 match, and verifying that that interface is declared in an instance.
378 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
380 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
381 assertions; replace function versions of Next_Formal/Next_Actual with
382 their procedural versions (which are more concise).

451 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
452 declaration is inserted into the tree and analyzed at that point, so
453 should not be reinserted when the body is constructed. Inside a
454 generic, ensure that the body is not inserted twice in the tree.
456 2018-05-25 Yannick Moy <moy@adacore.com>

491 * exp_ch8.adb (Build_Body_For_Renaming): Adding support to build the
492 body of a variant record equality renaming.
493 (Expand_N_Subprogram_Renaming_Declaration): Adapt the code to the new
494 implementation of Build_Body_For_Renaming.
495 * exp_ch3.ads (Build_Variant_Record_Equality): New library level
496 function that factorizes the functionality needed by
497 Build_Body_For_Renaming and Expand_Freeze_Record_Type to build the body
498 of a variant record equality subprogram.

1549 Address, and type of Low, High to Storage_Offset.
1550 (Low): Rename as Low_Address and convey that the return value is a
1551 runtime reference accounting for a load address.

1612 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
1613 delegate the secondary stack management when there is no suitable
1614 transient context, and the transient scope was intended to manage the

1616 transient scope creation logic by special casing assignment statements
1617 of controlled components for type initialization procedures.

1619 the comment on usage.
1620 (Find_Transient_Context): Change the initinte loop into a while loop.

1622 contexts because they rely on special processing. Assignment statements
1623 are now treated as a normal transient context, special cases are
1624 handled by the caller. Add special processing for pragma Check.
1625 (Is_OK_Construct): Removed. Its functionality has been merged in
1626 routine Find_Transient_Context.
1627 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly

1832 suitable construct to wrap, and the transient scope was intended to
1833 manage the secondary stack.
1834 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
1835 is a valid boundary for a transient expression which comes from the
1836 statements of the alternative, otherwise alternatives cannot be
1837 wrapped. Assignments of controlled objects which have controlled
1838 actions suppressed now stop the traversal as there is no point in
1839 looking for an enclosing construct. Add several N_xxx_Body choices to
1840 the termination conditions for completeness.

1847 (Resolve_Actuals): Account for additional cases where finalization
1848 actions are required by utilizing predicate Needs_Finalization rather
1850 (Resolve_Call): Type initialization procedures can now utilize
1851 transient scopes to manage the secondary stack, thus preventing leaks
1852 during initialization. Remove the previous kludgy algorithm which
1853 attempts to manage the secondary stack at the object creation site.

2039 relocated instead of evaluated. Discriminant of the corresponding
2040 record type is referenced rather than the type discriminant.
2041 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2042 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2043 * sem_ch13.adb (Analyze_One_Aspect): Transform
2044 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2045 because the attribute does not have visibility on a task type's
2046 discriminants when the type's definition is expanded.
2047 (Analyze_Attribute_Definition_Clause): Remove handling of
2048 Attribute_Secondary_Stack_Size.
2049 * snames.adb-tmpl, snames.ads-tmpl: Remove
2050 Attribute_Secondary_Stack_Size, no longer used.

2054 * sem_ch8.adb: Minor comment fix.
2056 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2058 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
2059 individual action because the action may denote a complex expression,
2060 such as a case statement, which in turn may contain additional
2063 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2065 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2066 analysis on a copy of the expression with a copy of the index variable,
2067 because full expansion will rewrite construct into a loop with the
2068 original loop variable.
2069 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2070 expression is an iterated component association. Full analysis takes
2071 place when construct is rewritten as a loop.
2072 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2073 is not safe for in-place assignment.
2074 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2075 entity with no homonym and no other entity in the scope.
2077 2018-01-11 Justin Squirek <squirek@adacore.com>
2079 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
2080 message to be printed on the pragma argument identifier.
2082 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2084 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
2085 entity of the generated invariant procedure in order to construct a
2086 proper entity chain.

2090 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
2093 2018-01-11 Arnaud Charlet <charlet@adacore.com>
2095 * einfo.ads, einfo.adb (Activation_Record_Component,
2096 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
2097 Allow E_Discriminant.
2099 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
2101 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
2102 for atomic access once the component size is taken into account and
2103 also do it if the component type is Atomic or Volatile_Full_Access.
2105 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
2107 * gnatvsn.ads: Bump copyright year.
