Bruce Evans d85327d7bc Stop using the alias `pcb_ptd' for` pcb_tcc.tss_cr3'. Use the (existing) alias `pcb_cr3' instead. That is still one alias too many, but is convenient for me since I've replaced the tss in the pcb by a few scalar variables in the pcb.		1996-06-08 11:03:19 +00:00

README.FreeBSD

This is a greatly pared down version of GDB-4.13 for FreeBSD 2.0. It
also has support for kernel debugging a la the dearly beloved kgdb.
Kernel debugging is enabled either using the -k flag or by linking gdb
to kgdb and invoking it as kgdb. Linking is left up to the discretion
of the user.

The kernel debugging needs testing, I didn't have any useful crash dumps
available. The new gdb produced the same output as the old kgdb with
what I had available for testing, though. 

There's rudimentary support for attaching to a running process and
debugging (attach/detach commands in gdb). This works best if the
program being debugged was compiled with -g, of course.

Note that a plain vanilla gdb-4.13 without kernal debugging or
attach/detach support can be made by removing the
	#define ATTACH_DETACH
	#define KERNEL_DEBUG
lines from gdb/nm.h.
