317 * freeze.adb (Freeze_Expression): Handle freeze of an entity defined
318 outside of a subprogram body. This case was previously handled during
319 preanalysis; the frozen entities were remembered and left pending until
320 we continued freezeing entities outside of the subprogram. Now, when
321 climbing the parents chain to locate the correct placement for the
322 freezeing node, we check if the entity can be frozen and only when no

335 Its code is basically the previous version of this routine but extended
336 with an additional parameter which is used to specify if during
337 preanalysis we are allowed to freeze entities. If the new parameter is
338 True then the subtree root node is marked as Must_Not_Freeze and no
339 entities are frozen during preanalysis.
340 (Preanalyze_And_Resolve): Invokes the internal version of
341 Preanalyze_And_Resolve without entity freezing.
342 (Preanalyze_With_Freezing_And_Resolve): Invokes the internal version of

377 enclosing scope already handles the secondary stack, take into account
378 transient blocks nested in a block that do not manage the secondary
379 stack and are located within a loop.
381 2018-07-17 Ed Schonberg <schonberg@adacore.com>
383 * sem_util.adb (Enclosing_Subprogram): Protected entries and task
384 entries must be treated separately: task entries are within the

1258 as reachable from outside the current unit. This includes entry bodies
1259 and protected operations.
1261 2018-05-31 Ed Schonberg <schonberg@adacore.com>
1263 * exp_ch4.adb (Expand_Modular_Addition, Expand_Modular_Subtraction):
1264 Convert all operands of the generated code to Standard.Unsigned, to
1265 prevent spurious visibility errors. This is needed when the generated
1266 expansion involves a modular index type of an array type, and the index
1267 type is not immediately visible.

1312 is now legal on a variable of composite type initialized with an
1313 aggregate that is fully static and requires no elaboration code.

1330 (Start_Search): Modify to use Start_Search_Internal
1331 (Start_Search_Internal): Add to break out an extra flag for searching
1332 case insensative due to the potential for directories within the same
1333 OS to allow different casing schemes.
1334 * sysdep.c (__gnat_name_case_equivalence): Add as a default fallback
1335 for when the more precise solution fails.

1404 comment about the memset case.
1406 2018-05-30 Bob Duff <duff@adacore.com>
1408 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
1409 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
1410 We need to analyze it as part of analyzing the block, so that if the
1411 call to Element that initializes Elmt_Decl returns on the secondary
1412 stack, the block will ss_mark/ss_release. This block is inside the
1413 loop; we don't want to leak memory until the loop exits. The purpose
1414 of analyzing Elmt_Decl first was to catch the error of modifying it,
1415 which is illegal because it's a loop parameter. The above causes us to
1416 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
1417 it on the Element entity, so we end up with an E_Variable node with the
1419 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
1420 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
1421 parameter not allowed" error if Is_Loop_Parameter.
1422 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
1423 trigger the call to Diagnose_Non_Variable_Lhs.
1425 2018-05-30 Arnaud Charlet <charlet@adacore.com>
1427 * checks.adb (Apply_Scalar_Range_Check):
1428 * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of
1429 range values for System.Priority in CodePeer mode since the actual
1430 target compiler may provide a wider range.
1432 2018-05-30 Ed Schonberg <schonberg@adacore.com>
1434 * exp_unst.adb: Search specification of main unit as well, for
1437 2018-05-30 Ed Schonberg <schonberg@adacore.com>
1439 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
1440 a package body that is a compilation unit may contain blocks that
1441 declare local subprograms. In Subprogram_Unnesting Mode such
1442 subprograms must be handled as nested inside the (implicit) elaboration
1443 procedure that executes that statement part. To handle properly uplevel
1444 references we construct that subprogram explicitly, to contain blocks
1445 and inner subprograms, The statement part of the compilation unit
1446 becomes a call to this subprogram. This is only done if blocks are
1447 present in the statement list of the body.
1449 2018-05-30 Bob Duff <duff@adacore.com>
1451 * exp_ch7.adb: Minor comment fix.

1457 corresponding wrapper package declaration.
1458 (Register_Subprogram): New subprogram, used for subprogram bodies and
1459 for subprogram instantiations to enter callable entity into Subp table.

1463 * libgnat/s-secsta.adb: Reimplement the secondary stack support.
1464 * libgnat/s-secsta.ads: Update the documentation of all routines in the
1465 public part of the package. Reimplement the private part of the
1466 package to account for the new secondary stack structure. Add types
1467 and subprograms for testing purposes. Add several documentation

1517 with a derivation of an untagged private type whose full view is a
1518 tagged type. In such case, collecting the list of primitives we may
1519 find two equality primitives: one associated with the untagged private

1580 * vx_crtbegin.inc: Use a consistent naming convention for the
1581 registration/deregistration functions across RTP or kernel. Remove the
1582 ctor/dtor attribute setting based on RTP/kernel, expect the optional
1583 attribute extension to be provided by includers instead.
1584 * vx_crtbegin.c: Mere inclusion of vx_crtbegin.inc with empty attribute
1585 extension for the registration/deregistration functions.

1723 To_Mixed): New functions.
1724 * osint.adb: Cleanup: use Is_Directory_Separator, which correctly
1725 allows both '\' and '/' on Windows.

1751 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1753 * exp_unst.adb (Visit_Node): For indexed components and attribute
1754 references, examine index expressions or associated expressions as well
1755 to record uplevel references.
1756 (Vist_Node): For function and procedure calls, if a formal is an
1757 unconstrained array and the actual is constrained, check whether bounds
1758 of actual have uplevel references.
1760 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1762 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
1763 they can appear as components of activation records.

1770 depends on a discriminant manually instead of using the predicate
1771 Size_Depends_On_Discriminant in the array type case.
1773 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1775 * exp_unst.adb (Check_Static_Type): For a record subtype, check
1776 discriminant constraints as well.
1777 (Visit_Node): For a selected component, check type of prefix, as is
1778 done for indexed components and slices.
1780 2018-05-28 Javier Miranda <miranda@adacore.com>
1782 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1783 value when converting a float value to a fixed-point value. This is
1784 required for CCG because it handles fixed-point types by means of
1785 unsigned integer type variables. The range check is now performed using
1786 the integer value stored in this temporary.
1788 2018-05-28 Yannick Moy <moy@adacore.com>
1790 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and

1801 (Inherited_Subprograms): Instance of Generic_Inherited_Subprograms with
1802 Sem_Disp.Find_Dispatching_Type.
1803 (Is_Overriding_Subprogram): Instance of
1804 Generic_Is_Overriding_Subprogram with Sem_Disp.Find_Dispatching_Type.

1806 with Sem_Disp.Find_Dispatching_Type.
1808 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1810 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
1811 component type, do not expand array equality using the unconstrained
1812 base type, except for the case where the bounds of the type depend on a
1815 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1817 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
1818 access-to-subprogram types, to indicate that an indirect call through
1819 such a type requires an activation record when compiling for LLVM.
1820 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
1822 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1824 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1825 when bounds of fixed type are static, to remove some spuerfluous
1826 implicit conversions and provide an accurate result when converting
1827 back and forth between the fixed point type and a floating point type.
1829 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1831 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
1834 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1836 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1837 replaced, if any; all callers changed.
1838 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1839 constant with private view so we take the address of that entity.
1840 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1841 any; all callers changed. Handle N_Indexed_Component like
1842 N_Attribute_Reference. Add N_Type_Conversion case.
1843 (Visit_Node): Indexed references can be uplevel if the type isn't
1845 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1846 been relocated, set first_named pointer in original node as well.
1848 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1850 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1851 association with a range or a set of discrete choices, rather than
1852 relocating the node. This avoids inconsistencies in the tree when
1853 handling nested subprograms with uplevel references for LLVM.

1896 used to determine how to generate an Init_Proc for a given type.
1897 (Needs_Constant_Address): Minor reformatting
1899 (Resolve_Null): Add logic to generate a conditional check in certain cases

1906 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1908 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1909 the declarations of single concurrent types because they fall in the
1910 category of full type and object declarations.
1912 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1914 * repinfo.adb (Compute_Max_Length): Skip _Parent component.

1917 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1919 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1920 includes a call to function to which it applies. This may mean an
1921 omission of an attribute reference 'Result, in particular if the
1922 function is pqrameterless.
1924 2018-05-28 Justin Squirek <squirek@adacore.com>

1931 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
1932 GNATprove mode, as the order of resolution (low then high) means that

1938 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1939 end with the linker section, if any.
1940 (List_Entities): Do not output the linker section for record types,
1941 array types and variables.
1942 (Print_Expr): Factor out common processing for unary operators and
1943 special values. Adjust and reorder the various cases.
1944 (List_Object_Info): End with the linker section, if any.
1945 (List_Record_Info): Likewise.
1946 (List_Type_Info): Do not start with a blank line.
1948 2018-05-25 Nicolas Roche <roche@adacore.com>
1950 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
1951 that the result will be either -infinite or +infinite.
1953 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
1955 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,
1956 libgnat/s-parame__ae653.ads, libgnat/s-parame__hpux.ads (Size_Type):
1957 Expand range of type to match the address space of the target.
1958 (Task_Storage_Size): Remove unused type.
1960 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1962 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1963 of a fixed point type and the parent is a multiplying operation,
1964 resolve the operand with its own type because the context will impose a
1965 resulting type on the result of the multiplication by means of
1966 approriate conversion.
1968 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1970 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1971 the in-place initialization aggregate created for pragmas
1972 Initialize_Scalars or Normalize_Scalars is performed with checks
1975 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1977 * exp_aggr.adb (Convert_To_Positional): Bump default for
1978 Max_Others_Replicate to 32. Update comments.
1979 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
1980 (No_File_Info_Cache): Initialize separately.

1985 * sem_res.adb (Resolve_Membership_Op): Allow the use of the membership
1986 test when the left operand is a class-wide interface and the right
1987 operand is not a class-wide type.

1991 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1993 * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated
1994 in an others clause to prevent visibility issues with the generated

1997 (Check_Static_Component): Ditto.
1999 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2001 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
2002 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
2003 into three distring cases rather than in one loop which attempts to
2004 handle all three cases. This rewrite eliminates an issue where the last
2005 frame of the stack cannot be freed, thus causing the memory range of a
2006 new frame to approach the overflow point of the memory index type.
2007 Since the overflow is logically treated as a
2008 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
2009 (SS_Allocate_Static): New routine. The routine factorizes the static
2010 secondary stack-related code from the former SS_Allocate.
2012 2018-05-25 Sergey Rybin <rybin@adacore.com>
2014 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
2015 option for gnatelim.
2017 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2019 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
2020 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
2021 is created when the proper body of the stub is analyzed.
2022 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
2023 is the proper body of a subunit, the cloned body must be inserted in
2024 the declarative list that contains the stub.
2026 2018-05-25 Justin Squirek <squirek@adacore.com>
2028 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
2029 generate code for 6.5(8-10) so that we don't get an assertion error
2030 when dealing with an incomplete return type.
2032 2018-05-25 Arnaud Charlet <charlet@adacore.com>
2034 * pprint.adb (Expression_Name): Strip too long expressions to avoid
2035 carrying very large strings.
2037 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
2039 * switch-b.adb (Scan_Binder_Switches): binder switch -Q accepts Natural

2061 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2063 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
2064 Validate_Derived_Type_Instance, to verify that all interfaces
2065 implemented by the formal type are also implemented by the actual. The
2066 verification is complicated when an interface of the formal is declared
2067 in a generic unit and the actual is declared in an instance of it.
2068 There is currently no mechanism to relate an interface declared within
2069 a generic to the corresponding interface in an instance, so we must
2070 traverse the list of interfaces of the actual, looking for a name
2071 match, and verifying that that interface is declared in an instance.

3307 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
3308 delegate the secondary stack management when there is no suitable
3309 transient context, and the transient scope was intended to manage the

3314 the comment on usage.
3315 (Find_Transient_Context): Change the initinte loop into a while loop.

3545 (Resolve_Call): Type initialization procedures can now utilize
3546 transient scopes to manage the secondary stack, thus preventing leaks
3547 during initialization. Remove the previous kludgy algorithm which
3548 attempts to manage the secondary stack at the object creation site.

3593 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
3594 formsl type corresponding to the actual fixed point type is private,
3595 because in this case there can be no suspicious arithmetic operations
3596 in the generic unless they reference a formal subprogram. Clarify

3601 * exp_util.adb (Remove_Side_Effects): No action done for functions
3602 returning class-wide types since it requires generating code using
3603 'reference and the CCG target has no secondary stack.

3646 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
3647 has a delayed aspect which must be processed at the point the type is
3648 frozen. This mimics what is done when the predicate is provided by a

3671 does not set Default_SS_Size.
3673 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3675 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
3676 legality of an inherited operation that may require overriding, ignore
3677 primitive_wrappers that correspond to explicit operations that override
3678 an interface primitive.
3679 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
3680 operation to which the class-wide expression applies is a protected op.
3681 with a primitive_wrapper, verify that the updated inherited expression
3682 does not contain an internal call to a protected function. This
3683 completes the implementation of AI12-0166.
3685 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3687 * ali.adb: Document the remaining letters available for ALI lines.
3688 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
3689 * ali.ads: Update type With_Record. Field

3692 * csinfo.adb (CSinfo): Remove the setup for attribute
3693 Implicit_With_From_Instantiation.
3694 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
3695 either implicitly or explicitly withed.
3696 (Is_Implicit_With_Clause): New routine.

3704 (Implicit_With_On_Parent): Mark the with clause as generated for a
3706 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3707 instantiation are no longer marked as Implicit_With_From_Instantiation
3708 because they are already marked as implicit.
3709 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3710 which marks implicit with clauses as related to an instantiation.
3711 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3712 (Parent_With): New routine.
3713 (Set_Implicit_With_From_Instantiation): Removed.

3727 entity when the enclosing construct is a body.
3729 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3731 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3732 Secondary_Stack_Size handling as a pragma is now generated for the
3733 corresponding aspect instead of an attribute. Pragma expression is
3734 relocated instead of evaluated. Discriminant of the corresponding
3735 record type is referenced rather than the type discriminant.
3736 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3737 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3738 * sem_ch13.adb (Analyze_One_Aspect): Transform
3739 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3740 because the attribute does not have visibility on a task type's

3743 Attribute_Secondary_Stack_Size.
3744 * snames.adb-tmpl, snames.ads-tmpl: Remove

3753 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3754 individual action because the action may denote a complex expression,
3755 such as a case statement, which in turn may contain additional
3758 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3760 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3761 analysis on a copy of the expression with a copy of the index variable,
3762 because full expansion will rewrite construct into a loop with the
3763 original loop variable.
3764 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3765 expression is an iterated component association. Full analysis takes
3766 place when construct is rewritten as a loop.
3767 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3768 is not safe for in-place assignment.
3769 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3770 entity with no homonym and no other entity in the scope.
3772 2018-01-11 Justin Squirek <squirek@adacore.com>

3779 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
3780 entity of the generated invariant procedure in order to construct a
3781 proper entity chain.

3790 * einfo.ads, einfo.adb (Activation_Record_Component,
3791 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
3792 Allow E_Discriminant.
3794 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3796 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3797 for atomic access once the component size is taken into account and
3798 also do it if the component type is Atomic or Volatile_Full_Access.
3800 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
