(Use_One_Package): Add condition to check for "hidden" open scopes to avoid skipping over packages that have not been properly installed even though they are visible. 2017-11-09 Ed Schonberg * sem_ch4.adb (Analyze_Selected_Component): Reject properly a call to a private operation of a protected type, when the type has no visible operations. 2017-11-09 Javier Miranda * rtsfind.ads (RE_Id, RE_Unit_Table): Add RE_HT_Link. * exp_disp.adb (Make_DT): Initialize the HT_Link field of the TSD only if available. 2017-11-09 Bob Duff * exp_ch4.adb, exp_ch9.adb, exp_prag.adb, par-ch3.adb, sem_aggr.adb, sem_ch12.adb, sem_ch13.adb, sem_ch4.adb, sem_disp.adb, sem_prag.adb, sem_res.adb, sem_util.adb: Get rid of warnings about uninitialized variables. 2017-11-09 Yannick Moy * exp_disp.adb (Make_DT): Default initialize Ifaces_List and Ifaces_Comp_List. 2017-11-09 Pascal Obry * libgnarl/s-taprop__mingw.adb: On Windows, initialize the thead handle only for foreign threads. We initialize the thread handle only if not yet initialized. This happens in Enter_Task for foreign threads only. But for native threads (Ada tasking) we do want to keep the real handle (from Create_Task) to be able to free the corresponding resources in Finalize_TCB (CloseHandle). 2017-11-09 Yannick Moy * sem_attr.adb (Analyze_Attribute): Default initialize P_Type, P_Base_Type. (Error_Attr_P): Fix name in pragma No_Return. (Unexpected_Argument): Add pragma No_Return.

(Check_Interfaces): Default initialize Full_T_Ifaces and Priv_T_Ifaces, which seem to be left uninitialized and possibly read in some cases. * sem_dim.adb (Analyze_Aspect_Dimension_System): Retype Position more precisely. This requires to exchange the test for exiting in case of too many positions and the increment to Position, inside the loop. * sem_eval.adb (Eval_Concatenation): Default initialize Folded_Val, which cannot be read uninitialized, but the reasons for that are quite subtle. * sem_intr.adb (Check_Intrinsic_Call): Default initialize Rtyp. * sem_prag.adb (Collect_Subprogram_Inputs_Outputs): Default initialize Spec_Id. * sem_res.adb (Make_Call_Into_Operator): Default initialize Opnd_Type, and test for presence of non-null Opnd_Type before testing its scope, in a test which would read its value uninitialized, and is very rarely exercized (it depends on the presence of an extension of System). * sem_spark.ads: Update comment to fix name of main analysis procedure. * sem_warn.adb (Warn_On_Known_Condition): Default initialize Test_Result. * set_targ.adb (FailN): Mark procedure with No_Return. * stylesw.adb (Save_Style_Check_Options): Delete useless code to initialize all array Options to white space, as there is already code doing the same for the remaining positions in Options at the end of the procedure. 2017-11-09 Eric Botcazou * exp_ch11.adb (Possible_Local_Raise): Do not issue the warning for generic instantiations either. 2017-11-09 Piotr Trojanek * sem_prag.adb (Analyze_Part_Of): Reword error message.

Use this (versus Name_Id) to indicate which objects can have those special values. Valid_Name_Id could usefully be used all over the compiler front end, but that's too much trouble for now. If we did that, we might want to rename: Name_Id --> Optional_Name_Id, Valid_Name_Id --> Name_Id. For parameters of type Valid_Name_Id, remove some redundant tests, including the ones found by CodePeer. Use Is_Valid_Name instead of membership test when appropriate. (Error_Name_Or_No_Name): Delete this; it's no longer needed. * sem_ch2.adb (Analyze_Identifier): Use "not Is_Valid_Name" instead of "in Error_Name_Or_No_Name".

(New_Copy_Tree): Reimplemented. 2017-09-08 Ed Schonberg * sem_ch13.adb (Resolve_Aspect_Expressions): The expression for aspect Default_Value is a static scalar value, but it does not freeze the type. Yhis allows for subsequent representation clauses for the type. 2017-09-08 Javier Miranda * sem_ch8.adb (Find_Direct_Name.Undefined): Do not add entries into the undefined reference table when we are compiling with errors ignored. 2017-09-08 Ed Schonberg * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance check if the instance is within an enclosing instance body.

Decrementing it here can lead to negative values of Warnings_Treated_As_Errors, raising Constraint_Error in checks-on builds, and causing the compiler to return an error code in checks-off builds. 2017-09-08 Arnaud Charlet * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect entities of named concurrent types as Ref_Id and not of anonymous concurrent objects (because callers already know when a conversion is necessary and can easily do it); also, do not expect protected types or protected objects as Context_Id (because no flow-related SPARK pragmas are attached there); reflect these changes in a more precise comment. 2017-09-08 Olivier Hainque * g-altive.ads: Add documentation. 2017-09-08 Bob Duff * sem_util.ads, debug.adb: Minor comment fix. * erroutc.ads: Comment fix. 2017-09-08 Ed Schonberg * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check for compatibility of component types of formal and actual in an instantiation of a child unit, when the component type of the formal is itself a formal of an enclosing generic. 2017-09-08 Arnaud Charlet * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from sem_prag.adb to make it available for GNATprove; for concurrent types replace custom scope climbing with Scope_Same_Or_Within; for single concurrent objects add scope climbing (with Scope_Within), which was not there (that's the primary semantic change of this commit); also, when comparing a single concurrent object with its corresponding concurrent type rely on equality of types, not of objects (because that's simpler to code). * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads. (Analyze_Global_Item): adjust special-casing of references to the current instance of a concurrent unit in the Global contracts of task types and single tasks objects; similar for references in the protected operations and entries of protected types and single protected objects (in all these cases the current instance behaves as an implicit parameter and must not be mentioned in the Global contract). 2017-09-08 Arnaud Charlet * exp_ch6.adb (Expand_Call_Helper): Introduce temporary for function calls returning a record within a subprogram call, for C generation. 2017-09-08 Ed Schonberg * sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded name that designates the current instance of a child unit in its own body and appears as the prefix of a reference to an entity local to the child unit. * exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb: Minor reformatting. 2017-09-08 Yannick Moy * sem_res.adb (Resolve_Equality_Op): Do not warn on comparisons that may be intentional. 2017-09-08 Tristan Gingold * sem_warn.adb (Check_Unused_Withs): Remove test that disabled warnings on internal units in configurable run time mode. 2017-09-08 Bob Duff * sem_ch3.adb (Build_Derived_Private_Type): Inherit representation items from interfaces that the derived type implements, not just from the parent type. * sem_util.ads, sem_util.adb (Abstract_Interface_List): Change this to return an empty list when there are no interfaces. * einfo.ads, sem_ch13.adb: Minor comment fixes. * sem_attr.adb: Minor comment fix. 2017-09-08 Doug Rupp * sigtramp-vxworks.c [i386]: Adjust the kernel context for x86-vx7. 2017-09-08 Hristian Kirtchev * exp_ch4.adb (Expand_N_Allocator): Generate a call to Allocate_Any_Controlled when the allocation does not require any initialization. 2017-09-08 Hristian Kirtchev * sem_util.adb (Copy_Node_With_Replacement): Update the Renamed_Object field of a replicated object renaming declaration. 2017-09-08 Patrick Bernardi * exp_ch9.adb (Is_Pure_Barrier): Allow type conversions and components of objects. Simplified the detection of the Count attribute by identifying the corresponding run-time calls. 2017-09-08 Yannick Moy * exp_ch9.adb, exp_disp.adb, repinfo.adb, sem_ch12.adb, sem_dim.adb, sem_type.adb, sinfo.ads: Minor reformatting. 2017-09-08 Ed Schonberg * freeze.adb (Has_Incomplete_Compoent): New predicate, subsidiary of Freeze_Profile, used to inhibit the freezing of the profile of an expression function declared within a nested package, when some type in the profile depends on a private type declared in an enclosing package. 2017-09-08 Bob Duff * gnat1drv.adb (Gnat1drv): Do not set the Force_ALI_Tree_File flag in the subunit case. It's still OK to set it in the "missing subunits" case, because that won't cause the obsolete .ali files that cause confusion. 2017-09-08 Bob Duff * sinput-l.adb: Remove unused "with Unchecked_Conversion;". It's unclear why this didn't cause a warning. * a-uncdea.ads, a-unccon.ads: Add "Ada." to names in the pragmas. It's unclear why this didn't cause an error. 2017-09-08 Hristian Kirtchev * exp_spark.adb (Expand_SPARK_N_Object_Renaming_Declaration): Reimplemented. (Expand_SPARK_Potential_Renaming): Code clean up. * sem_prag.adb (Analyze_Initialization_Item): Add a guard in case the item does not have a proper entity. (Analyze_Input_Item): Add a guard in case the item does not have a proper entity. (Collect_States_And_Objects): Include object renamings in the items being collected. (Resolve_State): Update the documentation of this routine. * sem_util.adb (Entity_Of): Add circuitry to handle renamings of function results. (Remove_Entity): New routine. (Remove_Overloaded_Entity): Take advantage of factorization. * sem_util.ads (Entity_Of): Update the documentation of this routine. (Remove_Entity): New routine. (Remove_Overloaded_Entity): Update the documentation of this routine. 2017-09-08 Eric Botcazou * repinfo.adb (List_Record_Info): During first loop, do not override the normalized position and first bit if they have already been set. Move fallback code for the packed case to the case where it belongs. * sem_ch13.adb (Adjust_Record_For_Reverse_Bit_Order): Also adjust the normalized position of components. (Adjust_Record_For_Reverse_Bit_Order_Ada_95): Likewise. 2017-09-08 Ed Schonberg * exp_disp.adb (Make_DT, Set_All_DT_Position): Handle properly the placement of a primitive operation O that renames an operation R declared in an inner package, and which is thus not a primitive of the dispatching type of O. In this case O is a new primitive and does not inherit its dispatch table position from R (which has none). 2017-09-08 Ed Schonberg * sem_dim.adb (Analyze_Dimension_If_Expression, Analyze_Dimension_Case_Expression): new subprograms to verify the dimensional correctness of Ada2012 conditional expressions, and set properly the dimensions of the construct. * sem_res.adb (Resolve_If_Expression, Resolve_Case_Expression)): call Analyze_Dimension. 2017-09-08 Ed Schonberg * sem_type.adb (Expand_Interface_Conversion): Prevent an infinite loop on an interface declared as a private extension of another synchronized interface. 2017-09-08 Ed Schonberg * sem_ch12.adb (Check_Generic_Parent): New procedure within Analyze_Associations, to handle actual packages that depend on previous instances. If a package IAP that is an instantiation is used as an actual in a subsequent instantiation SI in the same scope, and IAP has a body, IAP must be frozen before SI. If the generic parent of IAP is itself declared in a previous instantiation in the same scope, that instantiation must also be frozen before SI. (Install_Body): Prevent double insertion of freeze node for instance. 2017-09-08 Hristian Kirtchev * sem_prag.adb (Resolve_State): Update the comment on documentation. Generate a reference to the state once resolution takes place. 2017-09-08 Ed Schonberg * sem_ch13.adb (Analyze_Aspect_Specifications, case Linker_Section): If the aspect applies to an object declaration with explicit initialization, do not delay the freezing of the object, to prevent access-before-elaboration in the generated initialization code. 2017-09-08 Ed Schonberg * a-wtdeio.adb (Put, all versions): Use Long_Long_Integer (Integer_Value (Item)) when the size of the fixed decimal type is larger than Integer. 2017-09-07 Eric Botcazou PR ada/82127 * gcc-interface/decl.c (copy_and_substitute_in_layout): Put the fields in order of increasing position in more cases. 2017-09-07 Yannick Moy * a-exetim-mingw.ads: Add contract Global=>null on all operations that are modeled as having no read or write of global variables in SPARK. 2017-09-07 Raphael Amiard * a-chtgop.adb, a-chtgop.ads (Generic_Iteration_With_Position): Added to Hmaps.Generic_Ops. * a-cohama.adb (Ada.Containers.Hmaps.Iterate): Pass proper position in cursors. * a-cihama.adb (Ada.Containers.Indefinite_Hmaps.Iterate): Pass pos in cursors. * a-cohase.adb (Ada.Containers.Hashed_Sets.Iterate): Pass proper position in cursors. 2017-09-07 Javier Miranda * sem_elab.adb (Check_Task_Activation): Adding switch -gnatd.y to allow disabling the generation of implicit pragma Elaborate_All on task bodies. 2017-09-07 Javier Miranda * exp_disp.adb (Make_Tags): Avoid suffix counter in the external name of the elaboration flag. Required to fix the regressions introduced by the initial version of this patch. 2017-09-07 Bob Duff * sem_ch6.adb (Analyze_Function_Return): Do not insert an explicit conversion to force the displacement of the "this" pointer to reference the secondary dispatch table in the case where the return statement is returning a raise expression, as in "return raise ...". 2017-09-07 Arnaud Charlet * sem_disp.adb (Is_User_Defined_Equality): Removed procedure. * sem_util.ads, sem_util.adb (Is_User_Defined_Equality): Copied procedure from sem_disp.adb. * sem_ch12.ads (Get_Unit_Instantiation_Node): rename Package with Unit. * sem_ch12.adb (Get_Unit_Instantiation_Node): function extended to return the instantiation node for subprograms.

(Init_Secondary_Tags): Adding new formal (Init_Tags_List) and adjusting calls to Ada.Tags.Set_Dynamic_Offset_To_Top since it has a new formal; adjusting also calls to Ada.Tags.Register_Interface_Offset because the type of one of its formals has been changed. * a-tags.ads, a-tags.adb (Register_Interface_Offset): Profile modified.

Misc cleanup. * sem_util.ads, sem_util.adb (Unqual_Conv): New function to remove qualifications and type conversions. Fix various bugs where only a single level of qualification or conversion was removed, so e.g. "T1'(T2'(X))" would incorrectly return "T2'(X)" instead of "X". * checks.adb, exp_util.ads, exp_util.adb, sem_res.adb: Misc related cleanup. 2017-09-07 Ed Schonberg * sem_ch6.adb (setr_Actual_Subtypes): Within a predicate function do not create actual subtypes that may generate further predicate functions. * sem_ch13.adb (Build_Predicate_Functions): Indicate that entity of body is a predicate function as well.

Previously, the -do switch meant "run Elab_New and Elab_Old and use the order chosen by Elab_Old, possibly with debugging printouts comparing the two orders." Now it means "do not run Elab_New." This is of use if there are bugs that cause Elab_New to crash.

This is particularly relevant if the alternatives are aggregates. 2017-09-06 Ed Schonberg * checks.adb (Apply_Predicate_Check): If the expression is an aggregate that is the RHS of an assignment, apply the check to the LHS after the assignment, rather than to the aggregate. This is more efficient than creating a temporary for the aggregate, and prevents back-end crashes when the aggregate includes a dynamic "others' association. 2017-09-06 Yannick Moy * sem_ch12.adb (Analyze_Instance_And_Renamings): Set variable to ignore SPARK_Mode in instance before the analysis of the generated package declaration. 2017-09-06 Yannick Moy * sem_res.adb (Resolve_Call): Do not issue a message for calls inside expression function, unless body was seen and is candidate for inlining. 2017-09-06 Ed Schonberg * sem_aux.adb (Is_Generic_Formal): Handle properly formal packages. * sem_ch3.adb (Analyze_Declarations): In a generic subprogram body. do not freeze the formals of the generic unit. 2017-09-06 Gary Dismukes * errout.adb (Error_Msg): Separate the treatment for warning vs. style messages in inlinings and instantiations.

If the condition is inherited by a type extension, the prefix becomes a reference to the inherited operation, but there is no need to create a wrapper for this operation, because 'Result is expanded independently when elaborating the postconditions. 2017-04-27 Bob Duff * sinput.adb: Minor code cleanup. * namet.adb (Append): Create faster versions of Append(String) and Append(Name_Id) by using slice assignment instead of loops. * sem_util.adb (In_Instance): Speed this up by removing unnecessary tests; Is_Generic_Instance is defined for all entities. * sem_util.ads, sem_util.adb (In_Parameter_Specification): Remove unused function. * alloc.ads (Nodes_Initial): Use a much larger value, because the compiler was spending a lot of time copying the nodes table when it grows.

In Ada2012 'Image also belongs in this category, and A'Image (lo .. hi) is legal and must be parsed as a slice. 2017-04-27 Yannick Moy * exp_ch4.adb: Minor reformatting. * gnat1drv.adb (Adjust_Global_Switches): When in GNATprove mode, disable the CodePeer and C generation modes.

The loop now terminates much earlier as transient scopes are bounded by packages and subprograms. 2017-04-27 Claire Dross * a-cfdlli.adb, a-cfdlli.ads (=): Generic parameter removed to allow the use of regular equality over elements in contracts. (Cursor): Type is now public so that it can be used in model functions. (Formal_Model): Ghost package containing model functions that are used in subprogram contracts.

Switch -gnatd.s may be used to force strict management in which case the block will manage the secondary stack unconditionally. Add a guard to stop the traversal when encountering a package or a subprogram scope. 2017-04-27 Ed Schonberg * sem_res.adb (Resolve_Call): Refine further the handling of limited views of return types in function calls. If the function that returns a limited view appears in the current unit, we do not replace its type by the non-limited view because this transformation is performed int the back-end. However, the type of the call itself must be the non-limited view, to prevent spurious resolution errors. 2017-04-27 Ed Schonberg * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds): Removed, proposed implementation using generics for class-wide preconditions proved impractical. (Class_Wide_Clone): New attribute of subprogram. Designates subprogram created for primitive operations with class-wide pre/postconditions that contain calls to other primitives. The clone holds the body of the original primitive, but the pre/postonditions do not apply to it. The original body is rewritten as a wrapper for a call to the clone. (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If the flag is set, no code for the corresponding pre/postconditions is inserted into its body. 2017-04-27 Bob Duff * exp_prag.adb, par-prag.adb, sem_ch13.adb: Ignore Scalar_Storage_Order if -gnatI is given. * sem_prag.adb (Analyze_Pragma): Ignore Default_Scalar_Storage_Order if -gnatI is given. 2017-04-27 Claire Dross * a-cofuba.ads (Add): Take as an additional input parameter the position where the element should be inserted.

(Check_Fixed_Point_Actual): Do not emit a warning on a fixed point type actual that has user-defined arithmetic primitives, when there is a previous actual for a formal package that defines a fixed-point type with the parent user-defined operator. 2017-04-27 Hristian Kirtchev * checks.adb (Generate_Range_Check): Reinstate part of previous change. * sem_attr.adb (Resolve_Attribute): Generate a range check when the component type allows range checks. 2017-04-27 Ed Schonberg * sem_aux.adb (Is_Generic_Formal): Use original node to locate corresponding declaration, because formal derived types are rewritten as private extensions. 2017-04-27 Ed Schonberg * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check dimensions of operands if node has been analyzed already, because previous analysis and dimension checking will have removed the dimension information from the operands. 2017-04-27 Hristian Kirtchev * debug.adb: Document the use of switch -gnatd.s. * einfo.ads Update the documentation on attribute Sec_Stack_Needed_For_Return and attribute Uses_Sec_Stack.

Fix misc obscure bugs. * sinput.ads, sinput.adb: Use regular fat pointers, with bounds checking, for source buffers. Modify representation clause for Source_File_Record as appropriate. Move Source_File_Index_Table from spec to body, because it is not used outside the body. Move Set_Source_File_Index_Table into the private part, because it is used only in the body and in children. Use trickery to modify the dope in the generic instantiation case. It's ugly, but not as ugly as the previous method. Fix documentation. Remove obsolete code. * fname-sf.adb, targparm.adb: Fix misc out-of-bounds indexing in source buffers. * fmap.adb: Avoid conversions from one string type to another.

Add a condition to treat interface types as a partial view. * sem_prag.adb (Analyze_Pragma): Modify parameters in the call to Build_Invariant_Procedure_Declaration to properly generate a "partial" invariant procedure when Typ is an interface. 2017-04-25 Bob Duff * a-numeri.ads: Go back to using brackets encoding for the Greek letter pi. 2017-04-25 Ed Schonberg * sem_ch3.adb (Derive_Subprogram): Implement rule in RM 6.1.1 (10-15): if derived type T with progenitors is abstract, and primitive P of this type inherits non-trivial classwide preconditions from both a parent operation and from an interface operation, then the inherited operation is abstract if the parent operation is not null. * sem_disp.ads, sem_disp.adb: replace function Covers_Some_Interface with Covered_Interface_Op to yield the actual interface operation that is implemented by a given inherited operation. 2017-04-25 Javier Miranda * exp_ch4.adb (Expand_N_Op_Expon): Relocate left and right operands after performing the validity checks. Required because validity checks may remove side effects from the operands. 2017-04-25 Javier Miranda * exp_attr.adb (Attribute_Unrestricted_Access): Do not disable implicit type conversion. Required to generate code that displaces the pointer to reference the secondary dispatch table. 2017-04-25 Pascal Obry * prj-attr.adb, snames.ads-tmpl: Add package Install's Required_Artifacts attribute. 2017-04-25 Ed Schonberg * sem_util.adb (Same_Value): String literals are compile-time values, and comparing them must use Expr_Value_S. 2017-04-25 Ed Schonberg * sem_ch4.adb (Complete_Object_Interpretation): If an explicit dereference is introduced for the object, and the object is overloaded, do not check whether it is aliased, because it may include an implicit dereference. * sem_type.adb (Disambiguate): If two interpretations are access attribute types with the same designated type keep either of them and do not report an ambiguity. A true ambiguity will be reported elsewhere. 2017-04-25 Bob Duff * a-numeri.ads: Change the encoding of Greek letter Pi from brackets encoding to UTF-8. Use pragma Wide_Character_Encoding to indicate the encoding. We considered using a byte order mark (BOM), but that causes various trouble (misc software eats the BOM, if you have a patch with a BOM, then it's not at the start of the patch, so it's not a BOM, the BOM affects with-ing files, etc.). * scng.adb, s-wchcnv.adb: Minor. 2017-04-25 Hristian Kirtchev * sem_ch3.adb, sem_ch8.adb, sem_disp.adb: Minor reformatting. 2017-04-25 Ed Schonberg * sem_ch3.adb (Add_Internal_Interface_Entities): Move Has_Non_Trivial_Precondition to sem_util. for use elsewhere.

Set the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance when the corresponding spec also ignored all SPARK_Mode pragmas found within.

Set the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance when the corresponding instance spec also ignored all SPARK_Mode pragmas found within. * sem_prag.adb (Analyze_Pragma): Update the reference to Ignore_Pragma_SPARK_Mode. * sem_util.adb (SPARK_Mode_Is_Off): A construct which ignored all SPARK_Mode pragmas defined within yields mode "off". 2017-04-25 Hristian Kirtchev * bindgen.adb, exp_dbug.adb, errout.adb, fname.adb: Minor reformatting. 2017-04-25 Bob Duff * exp_atag.adb (Build_CW_Membership): Add "Suppress => All_Checks" to avoid generating unnecessary checks. * exp_ch4.adb (Expand_N_In, Make_Tag_Check): Add "Suppress => All_Checks". * sem.ads: Fix comment. * expander.ads: Fix comment. * exp_atag.ads: Fix comment: "Index = 0" should be "Index >= 0". 2017-04-25 Gary Dismukes * s-taprop-linux.adb: Minor editorial fixes. 2017-04-25 Eric Botcazou * sem_util.adb (New_Copy_Tree): Put back the declarations of the hash tables at library level. Reinstate the NCT_Hash_Tables_Used variable and set it to True whenever the main hash table is populated. Short- circuit the Assoc function if it is false and add associated guards. 2017-04-25 Olivier Hainque * bindgen.adb (Gen_Elab_Calls): Also update counter of lone specs without elaboration code that have an elaboration counter nevertheless, e.g. when compiled with -fpreserve-control-flow. * sem_ch10.adb (Analyze_Compilation_Unit): Set_Elaboration_Entity_Required when requested to preserve control flow, to ensure the unit elaboration is materialized at bind time, resulting in the inclusion of the unit object file in the executable closure at link time. 2017-04-25 Pierre-Marie de Rodat * exp_dbug.adb: In Debug_Renaming_Declaration, when dealing with indexed component, accept to produce a renaming symbol when the index is an IN parameter or when it is a name defined in an outer scope. 2017-04-25 Yannick Moy * errout.adb (Error_Msg): Adapt continuation message in instantiations and inlined bodies for info messages. 2017-04-25 Eric Botcazou * fname.adb (Has_Internal_Extension): Add pragma Inline. Use direct 4-character slice comparisons. (Has_Prefix): Add pragma Inline. (Has_Suffix): Delete. (Is_Internal_File_Name): Test Is_Predefined_File_Name first.

Specialize the error for the specless body case, as is done for (e.g.) pragma Convention. * debug.adb: Add switch -gnatd.J to disable the above legality checks. This is mainly for use in our test suite, to avoid rewriting a lot of illegal (but working) code. It might also be useful to customers. Under this switch, if a pragma No_Return applies to a body, and the procedure raises an exception (as it should), the pragma has no effect. If the procedure does return, execution is erroneous. 2017-04-25 Bob Duff * exp_ch6.adb (Expand_Actuals): This is the root of the problem. It took N as an 'in out' parameter, and in some cases, rewrote N, but then set N to Original_Node(N). So the node returned in N had no Parent. The caller continued processing of this orphaned node. In some cases that caused a crash (e.g. Remove_Side_Effects climbs up Parents in a loop, and trips over the Empty Parent). The solution is to make N an 'in' parameter. Instead of rewriting it, return the list of post-call actions, so the caller can do the rewriting later, after N has been fully processed. (Expand_Call_Helper): Move most of Expand_Call here. It has too many premature 'return' statements, and we want to do the rewriting on return. (Insert_Post_Call_Actions): New procedure to insert the post-call actions in the appropriate place. In the problematic case, that involves rewriting N as an Expression_With_Actions. (Expand_Call): Call the new procedures Expand_Call_Helper and Insert_Post_Call_Actions. 2017-04-25 Ed Schonberg * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle properly type derived from generic formal types, to handle properly modified version of ACATS 4.1B B611017. 2017-04-25 Javier Miranda * exp_unst.adb (Subp_Index): Adding missing support for renamings and functions that return a constrained array type (i.e. functions for which the frontend built a procedure with an extra out parameter). 2017-04-25 Pascal Obry * s-string.adb: Minor code clean-up. 2017-04-25 Bob Duff * s-os_lib.ads, s-os_lib.adb (Non_Blocking_Wait_Process): New procedure. * adaint.h, adaint.c (__gnat_portable_no_block_wait): C support function for Non_Blocking_Wait_Process. 2017-04-25 Bob Duff * prep.adb (Preprocess): Remove incorrect Assert. Current character can be ASCII.CR. 2017-04-25 Ed Schonberg * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for convention Stdcall, which has a number of exceptions. Convention is legal on a component declaration whose type is an anonymous access to subprogram. 2017-04-25 Hristian Kirtchev * sem_ch4.adb: sem_ch4.adb Various reformattings.

(Temp_File_Record): Add File component, so Close can know which Temp_File_Record corresponds to the file being closed. (Delete): Don't delete temp files, because they are deleted by Close. (Open): Set the File component of Temp_File_Record. This requires moving the creation of the Temp_File_Record to the end, after the AFCB has been created. 2017-04-25 Hristian Kirtchev * checks.adb (Insert_Valid_Check): Do not generate a validity check when inside a generic. 2017-04-25 Yannick Moy * sem_res.adb (Resolve_Type_Conversion): Fix bad logic. 2017-04-25 Arnaud Charlet * snames.ads-tmpl (Snames): More names for detecting predefined potentially blocking subprograms. 2017-04-25 Ed Schonberg * sem_prag.adb (Analyze_Pre_Post_Condition): The rules concerning inheritance of class-wide preconditions do not apply to postconditions. 2017-04-25 Bob Duff * s-ficobl.ads: Minor comment fix. 2017-04-25 Yannick Moy * checks.adb (Apply_Scalar_Range_Check): Analyze precisely conversions from float to integer in GNATprove mode. (Apply_Type_Conversion_Checks): Make sure in GNATprove mode to call Apply_Type_Conversion_Checks, so that range checks are properly positioned when needed on conversions, including when converting from float to integer. (Determine_Range): In GNATprove mode, take into account the possibility of conversion from float to integer. * sem_res.adb (Resolve_Type_Conversion): Only enforce range check on conversions from fixed-point to integer, not anymore on conversions from floating-point to integer, when in GNATprove mode. 2017-04-25 Yannick Moy * checks.adb (Determine_Range_R): Special case type conversions from integer to float in order to get bounds in that case too. * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove mode, for computations involved in interval checking. 2017-04-25 Hristian Kirtchev * checks.adb (Insert_Valid_Check): Partially reimplement validity checks. * einfo.adb Node36 is now used as Validated_Object.

This is only necessary for use clauses that appear in the parent of a generic child unit, because those use clauses get reanalyzed when we instantiate the generic, and we don't want the Used_Operations carried over from the original context (where it was probably not redundant). 2017-04-25 Hristian Kirtchev * exp_ch6.adb: Minor reformatting. 2017-04-25 Bob Duff * sem_prag.adb (Process_Restrictions_Or_Restriction_Warnings): Use Source_Index (Current_Sem_Unit) to find the correct casing. * exp_prag.adb (Expand_Pragma_Check): Use Source_Index (Current_Sem_Unit) to find the correct casing. * par.adb (Par): Null out Current_Source_File, to ensure that the above bugs won't rear their ugly heads again. 2017-04-25 Ed Schonberg * sem_ch8.adb (Find_Type): For an attribute reference 'Class, if prefix type is synchronized and previous errors have suppressed the creation of the corresponding record type, create a spurious class-wide for the synchonized type itself, to catch other misuses of the attribute 2017-04-25 Steve Baird * exp_ch6.adb (Expand_Simple_Function_Return): if CodePeer_Mode is True, then don't generate the accessibility check for the tag of a tagged result. * exp_intr.adb (Expand_Dispatching_Constructor_Call): if CodePeer_Mode is True, then don't generate the tag checks for the result of call to an instance of Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a descendant of" check and the accessibility check). 2017-04-25 Ed Schonberg * sem_ch13.adb: Code cleanups. * a-strbou.ads: minor whitespace fix in Trim for bounded strings. * sem_ch8.ads: Minor comment fix. 2017-04-25 Eric Botcazou * exp_ch4.adb (Library_Level_Target): New function.

If the prefix is an object this is an external call (or requeue) that can only access public operations of the object.

(Check_Aspect_At_Freeze_Point): Add aspect to list of aspects that don't require delayed analysis. * sem_prag.adb (Analyze_Pragma): Add case statement for Pragma_Max_Queue_Length, check semantics, and register arugments in the respective entry nodes. * sem_util.adb, sem_util.ads Add functions Get_Max_Queue_Length and Has_Max_Queue_Length * snames.ads-tmpl: Add constant for the new aspect-name Name_Max_Queue_Length and corrasponding pragma. 2017-01-06 Hristian Kirtchev * exp_util.adb (Is_Controlled_Function_Call): Reimplemented. Consider any node which has an entity as the function call may appear in various ways. 2017-01-06 Hristian Kirtchev * exp_attr.adb (Rewrite_Stream_Proc_Call): Use an unchecked type conversion when performing a view conversion to/from a private type. In all other cases use a regular type conversion to ensure that any relevant checks are properly installed. 2017-01-06 Hristian Kirtchev * sem_prag.adb, sem_ch8.adb: Minor reformatting. 2017-01-06 Ed Schonberg * sem_case.adb (Explain_Non_Static_Bound): Suppress cascaded error on case expression that is an entity, when coverage is incomplete and entity has a static value obtained by local propagation. (Handle_Static_Predicate): New procedure, subsidiary of Check_Choices, to handle case alternatives that are either subtype names or subtype indications involving subtypes that have static predicates. 2017-01-06 Thomas Quinot * s-oscons-tmplt.c, g-socket.adb, g-socket.ads, g-sothco.ads: (GNAT.Socket): Add support for Busy_Polling and Generic_Option 2017-01-06 Bob Duff * sem_elab.adb (Activate_Elaborate_All_Desirable): Don't add Elaborate_All(P) to P itself. That could happen in obscure cases, and always introduced a cycle (P body must be elaborated before P body). * lib-writ.ads: Comment clarification. * ali-util.ads: Minor comment fix. * ali.adb: Minor reformatting. 2017-01-06 Tristan Gingold * a-exexpr-gcc.adb: Improve comment. 2017-01-03 James Cowgill * s-linux-mips.ads: Use correct signal and errno constants. (sa_handler_pos, sa_mask_pos): Fix offsets for 64-bit MIPS. 2017-01-03 James Cowgill * s-linux-mips.ads: Rename from s-linux-mipsel.ads. * gcc-interface/Makefile.in (MIPS/Linux): Merge mips and mipsel sections. 2017-01-01 Eric Botcazou * gnatvsn.ads: Bump copyright year. 2017-01-01 Jakub Jelinek * gnat_ugn.texi: Bump @copying's copyright year. * gnat_rm.texi: Likewise.
