- About COP
-
- COP is a low level debugger for all amiga systems. "Low Level" means it
- directly plays with the hardware, does not have GUI, but is unbeatable
- stable. Its main purpose is to debug programs not debugable with the usual
- "source level" debugger, like hardware device drivers, DOS handlers in action
- and much more. It supports debugging by the serial port, thru a standard
- tty terminal (also a COP type 5 terminal is better. A terminal program
- for amigas is included), and a build-in terminal emulation in case no
- second computer is available.
-
- In case you want to use COP, make sure:
-
- -that you really want it. COP is not easy to use!
- -that you know assembly language. It won't work without!
- -that you have a lot of good will!

-
-
- By the way: You should read the documentation first (before trying to get
- COP running)!
-
- This is even more important if you own a '060 or '040 system. Special hints
- can be found at the end of the COP.doc file.

-
- Changes made in 1.65:
-
- - Fixed a bug in the 68851 detection routine. This thing is now getting
- "metamagical", too. As the rest of the kernal code...
- Thanks, Dennis, for letting me know.
- - COP RESTOREVBR restores now, too ,the Alert entry that might have been
- reset by the Enforcer.
- - Removed a bug from the symbol hunk parser that didn't respect HUNK_DEBUGs
- as it should.
- _____________________________________________________________________________
-
- Changes made in 1.64:
-
- - Fixed another set of bugs in the disassembler. The "pmove bad/bac" opcoded
- did not work.
- - The disassembler knows now the "fnop" command.
- - The register saveback routine was faulty for the '020 - it tried to save
- the non-existing tt0,tt1 registers.
- _____________________________________________________________________________
-
- Changes made in 1.63:
-
- - Fixed a bug in the disassembler. The 0x7100 opcode was not detected as
- illegal.
- - Fixed memory addressing bugs in the disassembler. Did not check for
- validity of addresses.
- - Fixed an addressing bug in the label manager. Did not check whether an
- address is valid or not.
- - COP does no longer run the ROM code for the '060 in case no Enforcer/060
- library is installed.
- - Added support code for the 68851 PMMU coprocessor. Should be detected
- correctly now.
- _____________________________________________________________________________
-
- Changes made in 1.62:
-
- - Neither the NOMMU nor the NOEMU command line options worked in 1.61.
- Sigh.
- - Added MMU and EMU keywords for symmetry.
- - Fixed just another bug in the '060 support code, thanks to Mark for
- the hints and the testing. (I guess we're at 4% now).
- - Added the MMU support for MOVE, FIND and FILL commands.
- - Improved FIND command, displays the found instructions or bytes.
- - Made RESTOREVBR a bit smarter.
- - Updated the included DDT file to contain '060 specific gurus. Thanks,
- Mark!
- ____________________________________________________________________________
-
- Changes made in 1.61:
-
- - Fixed a lot of bugs in the '060 support code. Thus, the chance that
- this release operates properly on a '060 has about doubled (from 1% to
- 2%, to be precise...).
- - Added NOEMU command line switch to bypass emulator traps.
- - Added proper support for the '060 '040 MMU and cache.
- - Debugged the AbsExecBase move.l emulator for the '060. Might actually work
- by now, but is untested.
- - Changed some details in MMU handling.
- - Changed minor details for COP capturing its own bugs.
- - Added another function to the label manager, showing the label given an
- address - LABL.F command.
- - Fixed a bug in the memory manager that did not handle non-writable memory
- in the correct way.
- - Fixed a bug in the set-breakpoint logic.
- - Enhanced the stack traceback with the new label manager. It tries to find
- out the label names.
- _____________________________________________________________________________
-
- Changes made in 1.60:
-
- - Removed bugs in the breakpoint logic.
- - Added SegTracker support for the REGS.G and (new) SEGM commands.
- - Updated MMU/Enforcer support since I finally bought a real 68030.
- - Added the NOMMU command line switch to disable the MMU bypass.
- - Added the ability to pre-compile the DDT files for faster parsing
- with the "PRE" command line option.
- - Updated the Terminal program a bit.
- _____________________________________________________________________________
-
- Changes made in 1.59:
-
- - Removed a bug in the expression evaluator that made the indirection
- operator [] unuseable.
- - Removed a bug in the conditional break points.
- - Rewrote parts of the system segment.
- - Added support for the CyberGuard. That's not yet tested, however!
- - Added more '040 instructions I forgot.
- - Fixed a bug in the disassembler.
- - The previous fix of the "NODE" command broke it even more, fixed!
- - Fixed plain MC68000 support that was broken since 1.56.
- _____________________________________________________________________________
-
- Changes made in 1.58:
-
- -Added two '040 instructions I wasn't aware of.
- -Rewrote the complete math support, an FPU is no longer required.
- -Enhanced the "NODE" command, it displays now all additional information
- it can hold of.
- -Removed a stupid bug from the "NODE" command.
- -Added the "LABS" command to view the defined labels. Study the doc file for
- details.
-
- _____________________________________________________________________________
-
- Changes made in 1.57:
-
- -Added PAL/NTSC switch.
- -Added a check for many command that won't work in a splitted display.
-
- _____________________________________________________________________________
-
- Changes made in 1.56:
-
- -Removed a bug in the printer hardware driver that caused one additional
- character to be printed.
- -Added command to eject paper.
- -Added Enforcer support for the MC68020 and MC68030 CPUs.
- -Added partial MMU support, however no MMU related commands are available.
- Enforcer must be run for this purpose.
- -Added IRQ CopyBack mode.
- -Fixed several final bugs in the 1.55 release, esp. some MC68060 related,
- although the support isn't complete yet ('60 FPU support is still somewhat
- broken, as the FPU part must be re-written anyways).
