- Revision 1.2 1998/03/28 23:09:57 florian
- * secondin bugfix (m68k and i386)
- * overflow checking bugfix (m68k and i386) -- pretty useless in
- secondadd, since everything is done using 32-bit
- * loading pointer to routines hopefully fixed (m68k)
- * flags problem with calls to RTL internal routines fixed (still strcmp
- to fix) (m68k)
- * #ELSE was still incorrect (didn't take care of the previous level)
- * problem with filenames in the command line solved
- * problem with mangledname solved
- * linking name problem solved (was case insensitive)
- * double id problem and potential crash solved
- * stop after first error
- * and=>test problem removed
- * correct read for all float types
- * 2 sigsegv fixes and a cosmetic fix for Internal Error
- * push/pop is now correct optimized (=> mov (%esp),reg)
-
- Revision 1.1.1.1 1998/03/25 11:18:15 root
- * Restored version
-
- Revision 1.17 1998/03/10 16:43:34 peter
- * fixed Fatal error writting
-
- Revision 1.16 1998/03/10 01:17:30 peter
- * all files have the same header
- * messages are fully implemented, EXTDEBUG uses Comment()
- + AG... files for the Assembler generation
-
- Revision 1.15 1998/03/06 00:53:02 peter
- * replaced all old messages from errore.msg, only ExtDebug and some
- Comment() calls are left
- * fixed options.pas
-
- Revision 1.14 1998/03/04 01:35:15 peter
- * messages for unit-handling and assembler/linker
- * the compiler compiles without -dGDB, but doesn't work yet
- + -vh for Hint
-
- Revision 1.13 1998/03/03 16:45:25 peter
- + message support for assembler parsers
-
- Revision 1.12 1998/03/02 16:02:05 peter
- * new style messages for pp.pas
- * cleanup of pp.pas
-
- Revision 1.11 1998/03/02 01:49:40 peter
- * renamed target_DOS to target_GO32V1
- + new verbose system, merged old errors and verbose units into one new
- verbose.pas, so errors.pas is obsolete
