2003-11-17 Jerome Guitton <guitton@act-europe.fr>
* 5zthrini.adb: Remove the call to Init_RTS at elaboration, as it is already called in System.Threads. * 5ztiitho.adb (Initialize_Task_Hooks): Remove the registration of the environment task, as it has been moved to System.Threads.Initialization. 2003-11-17 Arnaud Charlet <charlet@act-europe.fr> * adaint.c (__gnatlib_install_locks): Only reference __gnat_install_locks on VMS, since other platforms can avoid using --enable-threads=gnat 2003-11-17 Richard Kenner <kenner@vlsi1.ultra.nyu.edu> * ada-tree.h: (TYPE_IS_PACKED_ARRAY_TYPE_P): New macro. * decl.c (gnat_to_gnu_entity, case E_Array_Subtype): Set TYPE_PACKED_ARRAY_TYPE_P. (validate_size): Do not verify size if TYPE_IS_PACKED_ARRAY_TYPE_P. Part of PR ada/12806 * utils.c (float_type_for_precision): Renamed from float_type_for_size. Use GET_MODE_PRECISION instead of GET_MODE_BITSIZE. 2003-11-17 Vincent Celier <celier@gnat.com> * gnatchop.adb (Error_Msg): New Boolean parameter Warning, defaulted to False. Do not set exit status to Failure when Warning is True. (Gnatchop): Make errors "no compilation units found" and "no source files written" warnings only. * make.adb (Gnatmake): When using a project file, set Look_In_Primary_Dir to False. (Configuration_Pragmas_Switch): Check for Global_Configuration_Pragmas and Local_Configuration_Pragmas in the project where they are declared not an extending project which might have inherited them. * osint.adb (Locate_File): If Name is already an absolute path, do not look for a directory. * par-ch10.adb (P_Compilation_Unit): If source contains no token, and -gnats (Check_Syntax) is used, issue only a warning, not an error. * prj.adb (Register_Default_Naming_Scheme): Add new component Project in objects of type Variable_Value. * prj.ads: (Variable_Value): New component Project * prj-nmsc.adb (Ada_Check.Warn_If_Not_Sources): No warning if source is in a project extended by Project. * prj-proc.adb (Add_Attributes): New parameter Project. Set component Project of Variable_Values to this new parameter value. (Expression): Set component Project of Variable_Values. (Process_Declarative_Items): Call Add_Attributes with parameter Project. Set the component Project in array elements. 2003-11-17 Sergey Rybin <rybin@act-europe.fr> * errout.adb: (Initialize): Add initialization for error nodes. * sem_ch12.adb (Initialize): Add missing initializations for Exchanged_Views and Hidden_Entities. 2003-11-17 Ed Schonberg <schonberg@gnat.com> * sem_ch12.adb (Copy_Generic_Node): Preserve entity when copying an already instantiated tree for use in subsequent inlining. (Analyze_Associations, Instantiate_Formal_Subprogram, Instantiate_Object): improve error message for mismatch in instantiations. * sem_ch6.adb (Build_Body_To_Inline): Major cleanup to handle instantiations of subprograms declared in instances. 2003-11-17 Javier Miranda <miranda@gnat.com> * sem_ch4.adb (Analyze_Allocator): Previous modification must be executed only under the Extensions_Allowed flag. 2003-11-17 Robert Dewar <dewar@gnat.com> * a-exexda.adb (Address_Image): Fix documentation to indicate leading zeroes suppressed. (Address_Image): Fix bug of returning 0x instead of 0x0 Minor reformatting (function specs). * einfo.ads: Minor fix for documentation of Is_Bit_Packed_Array (missed case of 33-63) * freeze.adb, sem_ch13.adb: Properly check size of packed bit array * s-thread.adb: Add comments for pragma Restriction * exp_aggr.adb, g-debuti.adb, par-ch4.adb, sem_aggr.adb, sem_ch6.adb, sprint.adb, xref_lib.adb: Minor reformatting 2003-11-17 Ed Falis <falis@gnat.com> * s-thread.adb: Added No_Tasking restriction for this implementation. 2003-11-17 Emmanuel Briot <briot@act-europe.fr> * xref_lib.adb (Parse_Identifier_Info): Add handling of generic instanciation references in the parent type description. 2003-11-17 GNAT Script <nobody@gnat.com> * Make-lang.in: Makefile automatically updated git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@73672 138bc75d-0d04-0410-961f-82ee72b054a4
