The kernel supported the IA32 debug registers, DR0-DR7, in
4.0-RELEASE, however, gdb did not make use of them until later.  IIRC,
gdb support for the debug registers came in the 4.1.1-RELEASE of
FreeBSD.

For a nice visual debugger, you can also give GVD (GNU Visual
Debugger) a try. See:

SoftICE is actually overkill; ddd and gdb are probably best,
unless you are talking protected mode code.

If your code is running in the kernel, you will want to
look at /sys/i386/conf/LINT, and look for the "DDB" and
"BREAK_TO_DEBUGGER" options.  That gives you access to a
non-visual SoftICE-like debugger, which is capable of
doing protected mode and user mode debugging.

I occasionally miss SoftICE's visual change notification
features.  8-(.

Try ald (assembly language debugger) from
http://ellipse.mcs.drexel.edu/ald.html

According to the author, it was tested with FreeBSD 4.1.1-STABLE.

Debuggers for FreeBSD

2001-05-29 Thread Nickolay A. Kritsky 

Hi all.
I am using assembly language to write some useful programs for my FreeBSD 3.3_release 
and i need some debugger. I am not happy with
gdb. Can you tell me if there is some Soft-ICE type debuggers under this OS ?
BTW - is it true that FreeBSD kernel started supporting DRx registers only from 
version 4.2? Do i need to upgrade?

Please cc me in reply, as i am not subscribed to the list.
Any help is very good! Thank you for attention.
