 603         (GNATBIND_OBJS): add g-crc32.o, a-tags.o, a-stream.o
 604         (GNATLS_RTL_OBJS): add g-crc32.o
 605         (GNATMAKE_RTL_OBJS): add g-crc32.o
 606
 607         * ali-util.adb:
 608         (CRC_Match): new function.
 609         (Get_File_Checksum): renamed Get_File_CRC. Use the GNAT.CRC32 unit
 610         instead of the previous simple checksum algorithm.
 611         (Time_Stamp_Mismatch): use CRC_Match for comparison.
 612         (Set_Source_Table): idem.
 613
 614         * ali-util.ads:
 615         (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
 616         instead of simple checksum.
 617         (CRC_Match): new function.
 618         (CRC_Error): new constant.
 619
 620         * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
 621         a CRC now and not a simple checksum. A CRC uses lower-case hex
 622         letters, fixes ambiguity in parsing.
 623
 624         * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
 625         is what this variable will store.

 628         (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
 629         rename All_Checksum_Match to All_CRC_Match. Change due to API

 631         CRC using GNAT.CRC32.
 632
 633         * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
 634         now and not anymore a simple checksum.
 635
 636         * lib-load.adb: Use Source_CRC instead of Source_Checksum in many
 637         places.
 638
 639         * lib-writ.adb (Write_ALI): Use Source_CRC instead of Source_Checksum.
 640
 641         * scans.adb:
 642         (Restore_Scan_State): rename Checksum to CRC.
 643         (Save_Scan_State): idem.
 644
 645         * scans.ads:
 646         With GNAT.CRC32.

 649
 650         * scn-nlit.adb: Rename many Accumulate_Checksum to Update (from
 651         GNAT.CRC32).  Update copyright notice.
 652
 653         * scn-slit.adb: Rename many Accumulate_Checksum to Update (from
 654         GNAT.CRC32).  Update copyright notice.
 655
 656         * scn.adb:
 657         (Accumulate_Checksum): removed.
 658         (Update): new procedure. Add a wide-character into the CRC.
 659
 660         * sinput-l.adb:
 661         (Complete_Source_File_Entry): use CRC32 instead of simple checksum.
 662         (Load_File): fix initialization of S (change Source_Checksum to
 663         Source_CRC)
 664
 665         * sinput-p.adb (Load_Project_File): rename Source_Checksum to
 666         Source_CRC in S initialization.
 667
 668         * sinput.adb (Source_Checksum): renamed to Source_CRC.
 669
 670         * sinput.ads (Source_Checksum): renamed to Source_CRC.
 671         Update comments for the CRC.
 672
 673         * types.adb (Hex): Use lowercase for the letter part.
 674
 675         * types.ads (Get_Hex_String): Returns the hexadecimal representation
 676         for a word. This is currently used only for CRC. In previous version,
 677         the checksum was using a representation with all letter being
 678         upper-case. With the new implementation (using CRC) we do not remove
 679         the 32th bit of the CRC, so we can have an upper-case starting letter
 680         in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
 681         It is ambigous since the CRC was optional and could be followed by
 682         options like EB, EE. So now this routines uses lower-case letter for
 683         the hexadecimal representation. Strange enough only lower case letters
 684         where checked in Scan_ALI (even if this was not a possible case).
 685
 686         * gnatvsn.ads (Library_Version): changed to 3.15a.
 687
 688         * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
 689         for the compiler.
 690
 691         * s-crc32.adb: Initial version from GNAT.CRC32. This is the version
 692         for the compiler.
 693
 694         * ali-util.adb: Redo previous change to avoid using word CRC everywhere
 695         Add 2001 to copyright notice
 696         (Accumulate_Checksum): Modify to use System.CRC32.
 697
 698         * ali-util.ads: Redo changes of previous revision to continue to use
 699         the word Checksum. Add 2001 to copyright notice.

 714         * lib-writ.adb: Undo previous change, not needed.

 716         * lib-writ.ads: Document that checksums use lower case,
 717         not upper case letters.
 718

 720
 721         * scans.ads: Undo previous change, not needed.
