gdb hardware breakpoints under Linux PPC?

[Craig Rodrigues]

Hello,

I am debugging a problem with an application that
works under x86 based Redhat Linux 6.2, but
suffers a bizarre memory corruption under LinuxPPC 2000-Q4.
I am using gdb version 5 (gdb 5.05 rpm that comes with LinuxPPC).

I would like to set a hardware watchpoint under gdb
on a certain region of memory, to see why it is getting
clobbered (the element getting clobbered under PPC is
a dynamically allocated structure in a linked list).  Does
gdb 5 support hardware watchpoints under Linux PPC?

Can someone give me an example of how to set a watchpoint?
The gdb manual is a bit vague in explaining this.

Thanks.
