[hatari-devel] Most wanted debugger/profiler feature or convenience?

[Eero Tamminen <oak@xxxxxxxxxxxxxx>]

Hi,

I have had quite a bit of free time this winter, so I could
do a lot of work on the profiler & debugger, but that's going
to end in few weeks.

Before that I could still do some smaller stuff to debugger
or profiler (besides documenting the new features), so...

What's your most wanted debugger/profiler feature or convenience?


Things that have been proposed so far, or which I've thought
of otherwise:

* Stack backtrace output option for breakpoints
  (when symbols are loaded)

* Improved Callgrind format output for Kcachegrind
  from the profile data

* Modifying disassembly to show symbol names for jumps/branches

* Being able to specify how many instructions/lines
  d/dd/m/dm commands show (not just set it in cnf file)

* hex/string search for RAM  [1]
	<start>[-<end>] "<string>"|<hex> [alignment]

* "info mmu" command to show MMU state(?)

* being able to specify which exceptions (with -D option)
  invoke the debugger:

devel/2012/11/msg00040.html

* Symbolic names for OS call numbers
  (just GEMDOS, BIOS & XBIOS as AES & VDI isn't single number)

* Any additional debugger variables (for use in breakpoints), e.g:
  - exception number
?

NOTE that the use of '"' for indicating strings in debugger commands
requires changing immediate expression evaluation marker to something
else, e.g. to '{}', see:
  http://lists.berlios.de/pipermail/hatari-devel/2011q2/003571.html

-> If such a syntax change is done, I'd like it done for a major Hatari
   release, as soon as possible.


As to other "debugging" features proposed earlier:

* Statusbar LED showing activity also for other HW things
  than HD, e.g. Blitter, and using different colors for
  different activities.

Question is, what all other HW activities that LED could/should show
(which are used rarely together), and what colors should be used
for them, so that they can be differentiated?

PS. Debugger GUI is out of question, it's several months full
time project.
