Fixes regression on ACATS C34005G. 2001-10-11 Robert Dewar * sem_ch5.adb (Analyze_Iteration_Scheme): Suppress warning on null loop in generic instance, since this is likely not very useful. 2001-10-11 Robert Dewar * restrict.adb (Disallow in No_Run_Time_Mode): Properly specialize the error message for high integrity mode. * rtsfind.adb (RTE): Give message if we try to find an entity that is not available in high integrity mode. * rtsfind.ads: (OK_To_Use_In_HIE_Mode): New array.

(Get_File_Checksum): renamed Get_File_CRC. Use the GNAT.CRC32 unit instead of the previous simple checksum algorithm. (Time_Stamp_Mismatch): use CRC_Match for comparison. (Set_Source_Table): idem. * ali-util.ads: (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC instead of simple checksum. (CRC_Match): new function. (CRC_Error): new constant. * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling a CRC now and not a simple checksum. A CRC uses lower-case hex letters, fixes ambiguity in parsing. * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this is what this variable will store. * bcheck.adb: Change reference to chechsum in comments by CRC. (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC. rename All_Checksum_Match to All_CRC_Match. Change due to API renaming since now GNAT does not use a simple checksum but a CRC using GNAT.CRC32. * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC now and not anymore a simple checksum. * lib-load.adb: Use Source_CRC instead of Source_Checksum in many places. * lib-writ.adb (Write_ALI): Use Source_CRC instead of Source_Checksum. * scans.adb: (Restore_Scan_State): rename Checksum to CRC. (Save_Scan_State): idem. * scans.ads: With GNAT.CRC32. (Checksum): rename to CRC. (Saved_Scan_State): Save_Checksum field renamed to Save_CRC * scn-nlit.adb: Rename many Accumulate_Checksum to Update (from GNAT.CRC32). Update copyright notice. * scn-slit.adb: Rename many Accumulate_Checksum to Update (from GNAT.CRC32). Update copyright notice. * scn.adb: (Accumulate_Checksum): removed. (Update): new procedure. Add a wide-character into the CRC. * sinput-l.adb: (Complete_Source_File_Entry): use CRC32 instead of simple checksum. (Load_File): fix initialization of S (change Source_Checksum to Source_CRC) * sinput-p.adb (Load_Project_File): rename Source_Checksum to Source_CRC in S initialization. * sinput.adb (Source_Checksum): renamed to Source_CRC. * sinput.ads (Source_Checksum): renamed to Source_CRC. Update comments for the CRC. * types.adb (Hex): Use lowercase for the letter part. * types.ads (Get_Hex_String): Returns the hexadecimal representation for a word. This is currently used only for CRC. In previous version, the checksum was using a representation with all letter being upper-case. With the new implementation (using CRC) we do not remove the 32th bit of the CRC, so we can have an upper-case starting letter in the CRC. This is not possible to parse in Scan_ALI (ali.adb). It is ambigous since the CRC was optional and could be followed by options like EB, EE. So now this routines uses lower-case letter for the hexadecimal representation. Strange enough only lower case letters where checked in Scan_ALI (even if this was not a possible case). * gnatvsn.ads (Library_Version): changed to 3.15a. * s-crc32.ads: Initial version from GNAT.CRC32. This is the version for the compiler. * s-crc32.adb: Initial version from GNAT.CRC32. This is the version for the compiler. * ali-util.adb: Redo previous change to avoid using word CRC everywhere Add 2001 to copyright notice (Accumulate_Checksum): Modify to use System.CRC32. * ali-util.ads: Redo changes of previous revision to continue to use the word Checksum. Add 2001 to copyright notice. * ali.adb: Undo some of previous changes, not needed. Keep the change for lower case letters in the checksum. * ali.ads: Undo previous change not needed. * bcheck.adb: Undo most of previous change, not needed. But do use Checksums_Match for checksum comparison. * gnatls.adb: Undo most of previous change, not needed. But do use Checksums_Match for comparing checksums. * lib-load.adb: Undo previous change, not needed. * lib-writ.adb: Undo previous change, not needed. * lib-writ.ads: Document that checksums use lower case, not upper case letters. * scans.adb: Undo previous change, not needed * scans.ads: Undo previous change, not needed. * scn-nlit.adb: Undo previous changes, not needed. * scn-slit.adb: Undo previous change, not needed. Fix header format. * scn.adb: (Accumulate_Checksum): Use System.CRC32. (Initialize_Checksum): New procedure. Remove other changes of previous revision. * sinput-p.adb: Undo previous change, not needed. * sinput.adb: Undo previous change, not needed. * sinput-l.adb: Undo previous change, not needed. * sinput.ads: Undo previous change, not needed. Keep only comment on new checksum algorithm * Makefile.in: Add s-crc32 as needed, remove g-crc32. Also remove a-tags and a-stream from GNAT sources. * ali.adb (Scan_ALI): fix typo introduce in latest check-in. * Makefile.in (GNATRTL_NONTASKING_OBJS): Add g-crc32.o. 2001-10-11 Geert Bosch * einfo.h: Regenerate. * nmake.ads: Regenerate. * nmake.adb: Regenerate. * sinfo.h: Regenerate. * treeprs.adb: Regenerate. 2001-10-10 Geert Bosch * gnat-style.texi: New file describing coding guidelines for Ada. 2001-10-10 Ed Schonberg * einfo.adb (Write_Entity_Flags): Elaboration_Entity_Required is Flag174. 2001-10-10 Geert Bosch * snames.ads: Add new names for project facility. * snames.adb: Update to reflect snames.ads changes. * snames.h: Update to reflect snames.ads changes. 2001-10-10 Vincent Celier * make.adb: (Add_Switches): reflect the changes for the switches attributes Default_Switches indexed by the programming language, Switches indexed by the file name. (Collect_Arguments_And_Compile): Idem. Reflect the attribute name changes. * prj-attr.adb: (Initialisation_Data): Change the names of some packages and attributes. (Initialize): process case insensitive associative arrays. * prj-attr.ads: (Attribute_Kind): Remove Both, add Case_Insensitive_Associative_Array. * prj-dect.adb: (Parse_Attribute_Declaration): For case insensitive associative arrays, set the index string to lower case. * prj-env.adb: Reflect the changes of the project attributes. * prj-nmsc.adb: Replace Check_Naming_Scheme by Ada_Check and Language_Independent_Check. * prj-nmsc.ads: Replaced Check_Naming_Scheme by 2 procedures: Ada_Check and Language_Independent_Check. * prj-proc.adb: (Process_Declarative_Items): For case-insensitive associative arrays, set the index string to lower case.

Removed Body_Part, Specification_Append, Body_Append, Separate_Append, Gnatmake, Gnatxref, Gnatfind, Gnatbind, Gnatlink. * prj.ads: (Ada_Default_Spec_Suffix, Ada_Default_Impl_Suffix): Add comments. * prj-nmsc.adb (Ada_Check): Test that Separate_Suffix is defaulted, not that it is Nil_Variable_Value. * prj.ads: Add ??? for uncommented declarations 2001-10-10 Ed Schonberg * sem_prag.adb: (Analyze_Pragma, case External): If entity is a constant, do not indicate possible modification, so that gigi can treat it as a bona fide constant. 2001-10-10 Robert Dewar * sem_prag.adb: Add processing for pragma External. * snames.ads: Add entry for pragma External. * par-prag.adb: Add pragma External. * snames.adb: Updated to match snames.ads. 2001-10-10 Ed Schonberg * exp_ch4.adb (Expand_N_Allocator): Generate meaningful names for a dynamic task if the allocator appears in an indexed assignment or selected component assignment. * exp_util.adb (Build_Task_Array_Image, Build_Task_Record_Image): For a dynamic task in an assignment statement, use target of assignment to generate meaningful name. 2001-10-10 Ed Schonberg * einfo.adb (Write_Field19_Name): Body_Entity is also defined for a generic package. * einfo.ads: Body_Entity is also defined for generic package.
