From 28ed91d40c6a1f579b76e546fa0ed42f8f28fd7b Mon Sep 17 00:00:00 2001 From: charlet Date: Mon, 15 Mar 2004 14:51:00 +0000 Subject: 2004-03-15 Jerome Guitton * 3zsoccon.ads: Fix multicast options. * s-thread.ads: Move unchecked conversion from ATSD_Access to Address in the spec. 2004-03-15 Robert Dewar * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when pragma used for a private type. * lib-xref.adb (Generate_Reference): Do not generate warning if reference is in a different unit from the pragma Unreferenced. * 5vtpopde.adb: Minor reformatting Fix casing of To_Task_ID * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing flag if we have an unchecked conversion to an access type in the same unit. 2004-03-15 Geert Bosch * a-ngcoty.adb (Modulus): In alternate formula for large real or imaginary parts, use Double precision throughout. * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only we want to be able to compile run-time with -gnata for testing, but this may also be instantiated in user code that is compiled with -gnata. 2004-03-15 Olivier Hainque * s-stalib.ads (Exception_Code): New type, to represent Import/Export codes. Having a separate type for this is useful to enforce consistency throughout the various run-time units. (Exception_Data): Use Exception_Code for Import_Code. * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of Natural and Integer in various places. (Register_VMS_Exception): Use Base_Code_In to compute the exception code with the severity bits masked off. (Register_VMS_Exception): Handle the additional exception data pointer argument. * raise.c (_GNAT_Exception structure): Remove the handled_by_others component, now reflected by an exported accessor. (is_handled_by): New routine to compute whether the propagated occurrence matches some handler choice specification. Extracted out of get_action_description_for, and expanded to take care of the VMS specifities. (get_action_description_for): Use is_handled_by instead of an explicit complex condition to decide if the current choice at hand catches the propagated occurrence. * raise.h (Exception_Code): New type for C. * rtsfind.ads (RE_Id, RE_Unit_Table): Add System.Standard_Library.Exception_Code, to allow references from the pragma import/export expander. * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For): New accessors to allow easy access to GNAT exception data characteristics. (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the redundant Handled_By_Others component, helper for the personality routine which will now be able to call the appropriate exception data accessor instead. * cstand.adb (Create_Standard): Adjust the type of the Import_Code component of Standard_Exception_Type to be the closest possible to Exception_Code in System.Standard_Library, that we cannot get at this point. Expand a ??? comment to notify that this type node should probably be rewritten later on. * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the registration call to include a pointer to the exception object in the arguments. * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In instead of int and explicit bitmasks. 2004-03-15 Vincent Celier * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED equivalent to /STATIC and /NOSTATIC equivalent to /SHARED. * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no longer needed now that it is in the spec of System.Tasking.Task_Attributes. * adaint.h, adaint.c: (__gnat_create_output_file): New function * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of = * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function. * make.adb (Gnatmake): Do not check the executable suffix; it is being taken care of in Scan_Make_Arg. (Scan_Make_Arg): Add the executable suffix only if the argument following -o, in canonical case, does not end with the executable suffix. When in verbose mode and executable file name does not end with executable suffix, output the executable name, in canonical case. * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing to avoid warnings when instantiating Ada.Task_Attributes. Minor reformating. * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries in the correct order. * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but redirect standard output and error to a file for the invocation of the compiler, then read the file. * prj-nmsc.adb (Find_Sources): Use the Display_Value for each directory, instead of the Value. (Find_Source_Dirs): Remove useless code & comments. 2004-03-15 Ed Schonberg * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a tagged type is inherited, and the parent operation is not frozen yet, force generation of a freeze node for the inherited operation, so the corresponding dispatch entry is properly initialized. (Make_Predefined_Primitive_Specs): Check that return type is Boolean when looking for user-defined equality operation. * exp_ch4.adb (Expand_Composite_Equality): Check that return type is boolean when locating primitive equality of tagged component. * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a bit-aligned field and the right-hand side a string literal, introduce a temporary before expanding assignment into a loop. * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for priority in full, to ensure that any expanded subepxressions of it are elaborated in the scope of the init_proc. * exp_prag.adb (Expand_Pragma_Import): Search for initialization call after object declaration, skipping over code that may have been generated for validity checks. * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown discriminants, ignore the known discriminants of its full view, if any, to check legality. * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained component if type has unknown discriminants. (Analyze_Private_Extension_Declaration): Discriminant constraint is null if type has unknown discriminants. * sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference for end label when present. * s-fileio.adb (Open): When called with a C_Stream, use given name for temporary file, rather than an empty string. 2004-03-15 Ed Falis * s-thread.adb: Removed, no longer used. 2004-03-15 Richard Kenner * decl.c (target.h): Now include. (gnat_to_gnu_entity, case E_Access_Type): Use mode derived from ESIZE in new build_pointer_from_mode calls for non-fat/non-thin pointer. (validate_size): For POINTER_TYPE, get smallest size permitted on machine. * fe.h: Sort Einfo decls and add Set_Mechanism. * Makefile.in: (LIBGNAT_SRCS): Remove types.h. (ada/decl.o): Depends on target.h. * trans.c (tree_transform, N_Unchecked_Type_Conversion): Do not use FUNCTION_BOUNDARY; always use TYPE_ALIGN. 2004-03-15 Thomas Quinot * 5ztpopsp.adb, 56tpopsp.adb: Fix spelling of Task_ID. * exp_ch4.adb (Expand_N_Indexed_Component): Do not call Insert_Dereference_Action when rewriting an implicit dereference into an explicit one, this will be taken care of during expansion of the explicit dereference. (Expand_N_Slice): Same. Always do the rewriting, even for the case of non-packed slices, since the dereference action generated by expansion of the explicit dereference is needed in any case. (Expand_N_Selected_Component): When rewriting an implicit dereference, analyze and resolve the rewritten explicit dereference so it is seen by the expander. (Insert_Dereference_Action): This procedure is now called only for the expansion of an N_Explcit_Dereference_Node. Do insert a check even for dereferences that do not come from source (including explicit dereferences resulting from rewriting implicit ones), but do not recursively insert a check for the dereference nodes contained within the check. (Insert_Dereference_Action): Clarify and correct comment. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@79494 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/ada/exp_ch3.adb | 37 +++++++++++++++++++++++++------------ 1 file changed, 25 insertions(+), 12 deletions(-) (limited to 'gcc/ada/exp_ch3.adb') diff --git a/gcc/ada/exp_ch3.adb b/gcc/ada/exp_ch3.adb index 92295eb8102..e6e42315eb2 100644 --- a/gcc/ada/exp_ch3.adb +++ b/gcc/ada/exp_ch3.adb @@ -4184,23 +4184,35 @@ package body Exp_Ch3 is -- (usually the inherited primitive address is inserted in the -- DT by Inherit_DT) - if Is_CPP_Class (Etype (Def_Id)) then - declare - Elmt : Elmt_Id := First_Elmt (Primitive_Operations (Def_Id)); - Subp : Entity_Id; + -- Similarly, if this is an inherited operation whose parent + -- is not frozen yet, it is not in the DT of the parent, and + -- we generate an explicit freeze node for the inherited + -- operation, so that it is properly inserted in the DT of the + -- current type. - begin - while Present (Elmt) loop - Subp := Node (Elmt); + declare + Elmt : Elmt_Id := First_Elmt (Primitive_Operations (Def_Id)); + Subp : Entity_Id; + + begin + while Present (Elmt) loop + Subp := Node (Elmt); + + if Present (Alias (Subp)) then + if Is_CPP_Class (Etype (Def_Id)) then + Set_Has_Delayed_Freeze (Subp); - if Present (Alias (Subp)) then + elsif Has_Delayed_Freeze (Alias (Subp)) + and then not Is_Frozen (Alias (Subp)) + then + Set_Is_Frozen (Subp, False); Set_Has_Delayed_Freeze (Subp); end if; + end if; - Next_Elmt (Elmt); - end loop; - end; - end if; + Next_Elmt (Elmt); + end loop; + end; if Underlying_Type (Etype (Def_Id)) = Def_Id then Expand_Tagged_Root (Def_Id); @@ -5275,6 +5287,7 @@ package body Exp_Ch3 is N_Subprogram_Renaming_Declaration) and then Etype (First_Formal (Node (Prim))) = Etype (Next_Formal (First_Formal (Node (Prim)))) + and then Base_Type (Etype (Node (Prim))) = Standard_Boolean then Eq_Needed := False; -- cgit v1.2.1
