- Revision 1.1.1.1.2.1 1998/08/13 17:41:24 florian
- + some stuff for the PalmOS added
-
- Revision 1.1.1.1 1998/03/25 11:18:13 root
- * Restored version
-
- Revision 1.13 1998/03/10 01:17:20 peter
- * all files have the same header
- * messages are fully implemented, EXTDEBUG uses Comment()
- + AG... files for the Assembler generation
-
- Revision 1.12 1998/03/09 12:58:11 peter
- * FWait warning is only showed for Go32V2 and $E+
- * opcode tables moved to i386.pas/m68k.pas to reduce circular uses (and
- for m68k the same tables are removed)
- + $E for i386
-
- Revision 1.11 1998/03/06 00:52:24 peter
- * replaced all old messages from errore.msg, only ExtDebug and some
- Comment() calls are left
- * fixed options.pas
-
- Revision 1.10 1998/03/02 01:48:43 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- verbose.pas, so errors.pas is obsolete
-
- Revision 1.9 1998/02/13 10:35:09 daniel
- * Made Motorola version compilable.
- * Fixed optimizer
-
- Revision 1.8 1998/02/12 11:50:13 daniel
- Yes! Finally! After three retries, my patch!
-
- Changes:
-
- Complete rewrite of psub.pas.
- Added support for DLL's.
- Compiler requires less memory.
- Platform units for each platform.
-
- Revision 1.7 1998/01/11 03:38:05 carl
- * bugfix op_reg_const , op3t was never initialized
-
- Revision 1.3 1997/12/09 13:46:42 carl
- + renamed pai_labeled68k --> pai_labeled
- + added extended size constant
-
- Revision 1.2 1997/11/28 18:14:37 pierre
- working version with several bug fixes
-
- Revision 1.1.1.1 1997/11/27 08:32:57 michael

- Pre-CVS log:
-
- History:
- 30th september 1996:
- + unit started
- 15th october 1996:
- + tai386 added
- + some code from asmgen moved to this unit
- 26th november 1996:
- + tai386_labeled
- ---------------------
- 3rd september 1997:
- + unit started
- 5th september 1997:
- + first version completed
- 24 september 1997:
- + minor fixes regarding register conventions (CEC)
- 26 september 1997:
- + added divs/muls tai68k constructor (CEC)
- + added mc68020 instruction types (CEC)
- + converted to work with v093 (CEC)
- 4th october 1997:
- + version v95 (CEC)
- + added floating point flags (CEC)
- + added op_reg_const opcode for LINK instruction. (CEC)
- + added floating point branch / flags (CEC)
- 2nd november 1997:
