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.
