Add a test of whether the (possible) dereference prefix is a variable, and also test whether that prefix might just be of an access type (occurs in some implicit dereference cases) rather than being an explicit dereference. Retrieve the Original_Node of the object name's main prefix and handle the possibility of that being a qualified expression. Remove special-case code for explicit dereferences that don't come from source. Add test for the renaming not being within a generic body for proper determination of whether a formal access type is known to be constrained (it is within a generic spec, but not in the body). Fix an existing incorrect test for renaming of a discriminant-dependent component of a untagged generic formal type being within a generic body, adding test of taggedness and calling In_Generic_Body (now properly checks for cases where the renaming is in a nongeneric body nested within a generic). Return False in cases where the selector is not a component (or discriminant), which can occur for prefixed-notation calls. 2018-12-03 Ed Schonberg * sem_res.adb (Apply_Check): For array types, apply a length check rather than a qualification, to avoid spurious errors when the value of a dependend expression has a matching length but different bounds from those of the type of the contect. 2018-12-03 Hristian Kirtchev * libgnat/a-calend.adb: Update the number of leap seconds.

Do not reuse the DECL of the implementation type for the original type. Tidy up. 2018-05-31 Eric Botcazou * einfo.ads (Object_Size_Clause): Declare. * einfo.adb (Object_Size_Clause): New function. * gcc-interface/utils.c (maybe_pad_type): Test Has_Size_Clause before retrieving Size_Clause and post the warning on the object size clause if Has_Object_Size_Clause is true. 2018-05-31 Javier Miranda * sem_util.ads, sem_util.adb (Find_Primitive_Eq): New subprogram. * exp_ch4.adb (Expand_Composite_Equality): Use the new subprogram Find_Primitive_Eq to search for the primitive of types whose underlying type is a tagged type. 2018-05-31 Yannick Moy * sem_prag.adb (Analyze_Pragma.Check_Loop_Pragma_Placement): Inverse order of treatment between nodes recognized as loop pragmas (or generated from one) and block statements. 2018-05-31 Doug Rupp * libgnat/s-osprim__posix2008.adb (Clock): Implement using clock_gettime. 2018-05-31 Ed Schonberg * exp_unst.ads, exp_unst.adb (In_Synchronized_Unit): New predicate to mark subprograms that cannot be eliminated because they must be treated as reachable from outside the current unit. This includes entry bodies and protected operations. 2018-05-31 Ed Schonberg * exp_ch4.adb (Expand_Modular_Addition, Expand_Modular_Subtraction): Convert all operands of the generated code to Standard.Unsigned, to prevent spurious visibility errors. This is needed when the generated expansion involves a modular index type of an array type, and the index type is not immediately visible. 2018-05-30 Piotr Trojanek * einfo.ads (Package_Instantiation): Update comment after a routine that uses this field has been renamed. 2018-05-30 Ed Schonberg * exp_ch11.adb (Replace_Raise_By_Goto): The transfomation is legal even if the local raise statement includes a string expression.

We need to analyze it as part of analyzing the block, so that if the call to Element that initializes Elmt_Decl returns on the secondary stack, the block will ss_mark/ss_release. This block is inside the loop; we don't want to leak memory until the loop exits. The purpose of analyzing Elmt_Decl first was to catch the error of modifying it, which is illegal because it's a loop parameter. The above causes us to miss that error. Therefore, we add a flag Is_Loop_Parameter, and set it on the Element entity, so we end up with an E_Variable node with the flag set. * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag. * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop parameter not allowed" error if Is_Loop_Parameter. * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to trigger the call to Diagnose_Non_Variable_Lhs. 2018-05-30 Arnaud Charlet * checks.adb (Apply_Scalar_Range_Check): * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of range values for System.Priority in CodePeer mode since the actual target compiler may provide a wider range. 2018-05-30 Ed Schonberg * exp_unst.adb: Search specification of main unit as well, for unnesting. 2018-05-30 Ed Schonberg * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of a package body that is a compilation unit may contain blocks that declare local subprograms. In Subprogram_Unnesting Mode such subprograms must be handled as nested inside the (implicit) elaboration procedure that executes that statement part. To handle properly uplevel references we construct that subprogram explicitly, to contain blocks and inner subprograms, The statement part of the compilation unit becomes a call to this subprogram. This is only done if blocks are present in the statement list of the body. 2018-05-30 Bob Duff * exp_ch7.adb: Minor comment fix. 2018-05-30 Ed Schonberg * exp_unst.adb (Visit_Node): Handle properly subprogram instantiations that have no corresponding body and appear as attributes of the corresponding wrapper package declaration.

This may mean an omission of an attribute reference 'Result, in particular if the function is pqrameterless. 2018-05-28 Justin Squirek * sem_ch8.adb (Find_Expanded_Name): Add extra guard to make sure the misresolved package name is not a case of mistaken identity. 2018-05-28 Yannick Moy * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in GNATprove mode, as the order of resolution (low then high) means that all the information is not available when resolving the low bound the first time. 2018-05-28 Eric Botcazou * repinfo.adb (List_Array_Info): Start with an explicit blank line and end with the linker section, if any. (List_Entities): Do not output the linker section for record types, array types and variables. (Print_Expr): Factor out common processing for unary operators and special values. Adjust and reorder the various cases. (List_Object_Info): End with the linker section, if any. (List_Record_Info): Likewise. (List_Type_Info): Do not start with a blank line. 2018-05-25 Nicolas Roche * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure that the result will be either -infinite or +infinite. 2018-05-25 Patrick Bernardi * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads, libgnat/s-parame__ae653.ads, libgnat/s-parame__hpux.ads (Size_Type): Expand range of type to match the address space of the target. (Task_Storage_Size): Remove unused type. 2018-05-25 Ed Schonberg * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression of a fixed point type and the parent is a multiplying operation, resolve the operand with its own type because the context will impose a resulting type on the result of the multiplication by means of approriate conversion. 2018-05-25 Hristian Kirtchev * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of the in-place initialization aggregate created for pragmas Initialize_Scalars or Normalize_Scalars is performed with checks suppressed. 2018-05-25 Arnaud Charlet * exp_aggr.adb (Convert_To_Positional): Bump default for Max_Others_Replicate to 32. Update comments. * osint.ads (Unknown_Attributes): No longer pretend this is a constant.

(Component_OK_For_Backend): Return false for a quantified expression. (Check_Static_Component): Ditto. 2018-05-25 Hristian Kirtchev * libgnat/s-secsta.adb (SS_Allocate): Reimplemented. (SS_Allocate_Dynamic): New routine. The allocation logic is now split into three distring cases rather than in one loop which attempts to handle all three cases. This rewrite eliminates an issue where the last frame of the stack cannot be freed, thus causing the memory range of a new frame to approach the overflow point of the memory index type. Since the overflow is logically treated as a too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error. (SS_Allocate_Static): New routine. The routine factorizes the static secondary stack-related code from the former SS_Allocate. 2018-05-25 Sergey Rybin * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U' option for gnatelim. 2018-05-25 Ed Schonberg * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone is created when the proper body of the stub is analyzed. * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body is the proper body of a subunit, the cloned body must be inserted in the declarative list that contains the stub. 2018-05-25 Justin Squirek * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to generate code for 6.5(8-10) so that we don't get an assertion error when dealing with an incomplete return type. 2018-05-25 Arnaud Charlet * pprint.adb (Expression_Name): Strip too long expressions to avoid carrying very large strings. 2018-05-25 Patrick Bernardi * switch-b.adb (Scan_Binder_Switches): binder switch -Q accepts Natural numbers. 2018-05-25 Doug Rupp * tracebak.c (aarch64-linux): Implement. 2018-05-25 Justin Squirek * sem_ch8.adb: Minor reformatting. 2018-05-25 Piotr Trojanek * sem_util.adb (Iterate_Call_Parameters): Fix code convention and assertions. 2018-05-25 Hristian Kirtchev * einfo.adb, einfo.ads, exp_ch3.adb, exp_ch8.adb, exp_unst.adb, pprint.adb, sem_ch12.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb: Minor reformatting. 2018-05-25 Ed Schonberg * sem_ch12.adb (Instance_Exists): New function, subsidiary of Validate_Derived_Type_Instance, to verify that all interfaces implemented by the formal type are also implemented by the actual. The verification is complicated when an interface of the formal is declared in a generic unit and the actual is declared in an instance of it. There is currently no mechanism to relate an interface declared within a generic to the corresponding interface in an instance, so we must traverse the list of interfaces of the actual, looking for a name match, and verifying that that interface is declared in an instance. 2018-05-25 Piotr Trojanek * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra assertions; replace function versions of Next_Formal/Next_Actual with their procedural versions (which are more concise). 2018-05-25 Doug Rupp * libgnarl/s-osinte__aix.ads, libgnarl/s-osinte__android.ads, libgnarl/s-osinte__darwin.ads, libgnarl/s-osinte__freebsd.ads, libgnarl/s-osinte__hpux.ads, libgnarl/s-osinte__kfreebsd-gnu.ads, libgnarl/s-osinte__linux.ads, libgnarl/s-osinte__lynxos178e.ads, libgnarl/s-osinte__qnx.ads, libgnarl/s-osinte__rtems.ads (Relative_Timed_Wait): Remove. * libgnarl/s-tpopmo.adb (Timed_Sleep, Timed_Delay): Rewrite to allow for incremental looping.

(Note_Uplevel_Bound): Verify that the bound is declared in an enclosing subprogram, as itype created for loops in pre/postcondition may appear in loops at the library level. 2018-05-25 Ed Schonberg * sem_ch13.adb (Build_Predicate_Functions): The predicate function declaration is inserted into the tree and analyzed at that point, so should not be reinserted when the body is constructed. Inside a generic, ensure that the body is not inserted twice in the tree. 2018-05-25 Yannick Moy * sem_prag.adb (Check_Grouping): Modify test to ignore statements and declarations not coming from source. 2018-05-25 Fedor Rybin * doc/gnat_ugn/gnat_utility_programs.rst: Document new switch --copy-environment for gnattest. 2018-05-24 Piotr Trojanek * sem_elab.adb (Non_Private_View): Simplify by removing a local Result variable. * sem_prag.adb (Get_Base_Subprogram): Same as above. 2018-05-24 Eric Botcazou * fe.h (Set_Normalized_First_Bit): Declare.

Fix formatting. (gnat_to_gnu) : Minor tweak. : Likewise. 2018-05-24 Javier Miranda * exp_ch8.adb (Build_Body_For_Renaming): Adding support to build the body of a variant record equality renaming. (Expand_N_Subprogram_Renaming_Declaration): Adapt the code to the new implementation of Build_Body_For_Renaming. * exp_ch3.ads (Build_Variant_Record_Equality): New library level function that factorizes the functionality needed by Build_Body_For_Renaming and Expand_Freeze_Record_Type to build the body of a variant record equality subprogram. * exp_ch3.adb (Build_Variant_Record_Equality): New subprogram. (Build_Variant_Record_Equality): New local procedure of Expand_Freeze_Record_Type containing all the code specific for freezing the record type that cannot be place in the new library level function. 2018-05-24 Ed Schonberg * einfo.ads, einfo.adb (Is_Activation_Record): New flag on in_parameters, used when unesting subprograms for LLVM, to indicate that a generated parameter carries the activation record from the enclosing subprogram. * exp_unst.adb (Check_Static_Type): Handle array attributes of types whose bounds may contain up-level references that need to be added to an activation recoord.

This may happen when the redundant clauses appear in the context of a child unit and the context of its parent. 2018-05-24 Piotr Trojanek * sinfo.ads: Fix grammar in comment. 2018-05-24 Justin Squirek * einfo.ads, einfo.adb (Append_Entity): Modified to use Link_Entities and manage doubly-linked entity chain. (Nested_Scenarios): Removed entity field used for optimization during elaboration to make room for the new field Prev_Entity.
