Instruction tracing

[Gareth <g.c.bransby-99@student.lboro.ac.uk>]

Hello,

I am trying to debug a program running on a mips malta dev board (no operating
system). I am using gdb running on a linux pc connected to the board via
serial and the board is running YAMON gdb. I can step through the code, set
break points, examine memory and variables etc, but what I would really like 
to do is get an instruction trace of the program. 

Any help greatly appreciated.
Gareth
