17 To_Mixed): New functions.
18 * osint.adb: Cleanup: use Is_Directory_Separator, which correctly

47 * exp_unst.adb (Visit_Node): For indexed components and attribute
48 references, examine index expressions or associated expressions as well
49 to record uplevel references.
50 (Vist_Node): For function and procedure calls, if a formal is an
51 unconstrained array and the actual is constrained, check whether bounds
52 of actual have uplevel references.
54 2018-05-28 Ed Schonberg <schonberg@adacore.com>
56 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
57 they can appear as components of activation records.

76 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
77 value when converting a float value to a fixed-point value. This is
78 required for CCG because it handles fixed-point types by means of
79 unsigned integer type variables. The range check is now performed using
80 the integer value stored in this temporary.
82 2018-05-28 Yannick Moy <moy@adacore.com>
84 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and
85 Length as valid non-interfering contexts for SPARK.

89 * sem_disp.ads, sem_disp.adb (Inheritance_Utilities): Package for
90 generic inheritance utilities.

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

114 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
116 2018-05-28 Ed Schonberg <schonberg@adacore.com>
118 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
119 when bounds of fixed type are static, to remove some spuerfluous
120 implicit conversions and provide an accurate result when converting
121 back and forth between the fixed point type and a floating point type.
123 2018-05-28 Ed Schonberg <schonberg@adacore.com>
125 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
128 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
130 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
131 replaced, if any; all callers changed.
132 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
133 constant with private view so we take the address of that entity.
134 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
135 any; all callers changed. Handle N_Indexed_Component like
136 N_Attribute_Reference. Add N_Type_Conversion case.
137 (Visit_Node): Indexed references can be uplevel if the type isn't
139 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
140 been relocated, set first_named pointer in original node as well.
142 2018-05-28 Ed Schonberg <schonberg@adacore.com>
144 * exp_aggr.adb (Flatten): Copy tree of expression in a component
145 association with a range or a set of discrete choices, rather than
146 relocating the node. This avoids inconsistencies in the tree when
147 handling nested subprograms with uplevel references for LLVM.

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

234 (List_Entities): Do not output the linker section for record types,
235 array types and variables.
236 (Print_Expr): Factor out common processing for unary operators and
237 special values. Adjust and reorder the various cases.

254 2018-05-25 Ed Schonberg <schonberg@adacore.com>
256 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
257 of a fixed point type and the parent is a multiplying operation,
258 resolve the operand with its own type because the context will impose a
259 resulting type on the result of the multiplication by means of
260 approriate conversion.
262 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
264 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
265 the in-place initialization aggregate created for pragmas
266 Initialize_Scalars or Normalize_Scalars is performed with checks
269 2018-05-25 Arnaud Charlet <charlet@adacore.com>
271 * exp_aggr.adb (Convert_To_Positional): Bump default for
272 Max_Others_Replicate to 32. Update comments.

295 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
296 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
297 into three distring cases rather than in one loop which attempts to
298 handle all three cases. This rewrite eliminates an issue where the last
299 frame of the stack cannot be freed, thus causing the memory range of a
300 new frame to approach the overflow point of the memory index type.
301 Since the overflow is logically treated as a
302 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
303 (SS_Allocate_Static): New routine. The routine factorizes the static
304 secondary stack-related code from the former SS_Allocate.
306 2018-05-25 Sergey Rybin <rybin@adacore.com>

313 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
314 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
315 is created when the proper body of the stub is analyzed.
316 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
317 is the proper body of a subunit, the cloned body must be inserted in
318 the declarative list that contains the stub.
320 2018-05-25 Justin Squirek <squirek@adacore.com>
322 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
323 generate code for 6.5(8-10) so that we don't get an assertion error
324 when dealing with an incomplete return type.
326 2018-05-25 Arnaud Charlet <charlet@adacore.com>

357 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
358 Validate_Derived_Type_Instance, to verify that all interfaces
359 implemented by the formal type are also implemented by the actual. The
360 verification is complicated when an interface of the formal is declared
361 in a generic unit and the actual is declared in an instance of it.
362 There is currently no mechanism to relate an interface declared within
363 a generic to the corresponding interface in an instance, so we must
364 traverse the list of interfaces of the actual, looking for a name
365 match, and verifying that that interface is declared in an instance.
367 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
369 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
370 assertions; replace function versions of Next_Formal/Next_Actual with

481 body of a variant record equality renaming.
482 (Expand_N_Subprogram_Renaming_Declaration): Adapt the code to the new
483 implementation of Build_Body_For_Renaming.
484 * exp_ch3.ads (Build_Variant_Record_Equality): New library level
485 function that factorizes the functionality needed by

1537 * libgnat/s-dwalin.ads (Dwarf_Context): Change type of Load_Address to
1538 Address, and type of Low, High to Storage_Offset.
1539 (Low): Rename as Low_Address and convey that the return value is a
1540 runtime reference accounting for a load address.
1541 * libgnat/s-dwalin.adb (Read_Aranges_Entry): Adjust to the
1542 address/offset type changes.
1543 (Aranges_Lookup): Likewise.
1544 (Symbolic_Address): Likewise.

1552 (Multi_Module_Symbolic_Traceback): Compare address in traceback
1553 with module Low_Address instead of Low.

1565 * libgnat/s-trasym__dwarf.adb (Add_Module_To_Cache): Expect a
1566 Load_Address argument and pass it down to Init_Module.
1567 * libgnat/s-tsmona__linux.adb (Build_Cache_For_All_Modules): Pass
1568 lm.l_addr as the Load_Address to Add_Module_To_Cache.
1570 2018-05-21 Piotr Trojanek <trojanek@adacore.com>
1572 * einfo.adb (Has_Discriminants): Stronger assertion.

1597 formal private type.
1599 2018-05-21 Hristian Kirtchev <kirtchev@adacore.com>
1601 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
1602 delegate the secondary stack management when there is no suitable
1603 transient context, and the transient scope was intended to manage the
1604 secondary stack because this causes premature reclamation. Change the
1605 transient scope creation logic by special casing assignment statements
1606 of controlled components for type initialization procedures.
1607 (Find_Node_To_Be_Wrapped): Renamed to Find_Transient_Context. Update
1608 the comment on usage.
1609 (Find_Transient_Context): Change the initinte loop into a while loop.
1610 Iterations schemes and iterator specifications are not valid transient
1611 contexts because they rely on special processing. Assignment statements
1612 are now treated as a normal transient context, special cases are
1613 handled by the caller. Add special processing for pragma Check.
1614 (Is_OK_Construct): Removed. Its functionality has been merged in
1615 routine Find_Transient_Context.
1616 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly
1617 retrieve the subprogram being invoked. Use a more accurate predicate
1618 (Requires_Transient_Scope) to determine that the function will emply
1619 the secondary stack.

1821 suitable construct to wrap, and the transient scope was intended to
1822 manage the secondary stack.
1823 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
1824 is a valid boundary for a transient expression which comes from the
1825 statements of the alternative, otherwise alternatives cannot be
1826 wrapped. Assignments of controlled objects which have controlled
1827 actions suppressed now stop the traversal as there is no point in
1828 looking for an enclosing construct. Add several N_xxx_Body choices to
1829 the termination conditions for completeness.

1831 and the associated comment on usage.

1836 (Resolve_Actuals): Account for additional cases where finalization
1837 actions are required by utilizing predicate Needs_Finalization rather
1839 (Resolve_Call): Type initialization procedures can now utilize
1840 transient scopes to manage the secondary stack, thus preventing leaks
1841 during initialization. Remove the previous kludgy algorithm which
1842 attempts to manage the secondary stack at the object creation site.

2025 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2026 Secondary_Stack_Size handling as a pragma is now generated for the
2027 corresponding aspect instead of an attribute. Pragma expression is
2028 relocated instead of evaluated. Discriminant of the corresponding
2029 record type is referenced rather than the type discriminant.

2037 Attribute_Secondary_Stack_Size.
2038 * snames.adb-tmpl, snames.ads-tmpl: Remove

2047 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
2048 individual action because the action may denote a complex expression,
2049 such as a case statement, which in turn may contain additional
2052 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2054 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2055 analysis on a copy of the expression with a copy of the index variable,
2056 because full expansion will rewrite construct into a loop with the
2057 original loop variable.
2058 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2059 expression is an iterated component association. Full analysis takes
2060 place when construct is rewritten as a loop.
2061 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2062 is not safe for in-place assignment.
2063 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2064 entity with no homonym and no other entity in the scope.
2066 2018-01-11 Justin Squirek <squirek@adacore.com>
2068 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
2069 message to be printed on the pragma argument identifier.
2071 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2073 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
2074 entity of the generated invariant procedure in order to construct a
2075 proper entity chain.

2082 2018-01-11 Arnaud Charlet <charlet@adacore.com>
2084 * einfo.ads, einfo.adb (Activation_Record_Component,
2085 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
2086 Allow E_Discriminant.
2088 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
2090 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
2091 for atomic access once the component size is taken into account and
2092 also do it if the component type is Atomic or Volatile_Full_Access.
2094 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
2096 * gnatvsn.ads: Bump copyright year.
