Cross gdb for ARM

Cross gdb for ARM

[Robert Schwebel]

Hi, 

which version of gdb/gdbserver is currently recommended for StrongARM?
I've tried 5.2 and 5.2.1, but both do not work. I can start the program
on the target remotely with "run", but I cannot set breakpoints. It
simply continues running and doesn't stop. 

I also wanted to try CVS, but it doesn't compile at the moment:

5.2 should work.  More details?

Get a 5.3 or trunk snapshot from the
sources.redhat.com/pub/gdb/snapshots directory; that won't include SID.

Daniel, Robert et al:

We at Cisco managed to get an ARM cross gdb working on 5.0
even though the FSF code was missing quite a bit.  I'm
interested in helping anyone else out with ARM x-gdb issues
or donating parts of it to the FSF (after it clears paperwork here).

Might I be able to help you out here?  The code was written by
myself (GDB Support) and Mickey Sartin (who works on the ARM
backend).

Hi Robert,

FWIW, I've been doing something similar, with gdb/gdbserver 5.2 and with
the 5.3 CVS branch (the main difference is that the 5.3 has thread
support, which Daniel did.  I tried this on mips and it works great, but
I've not tried it on arm yet).

As far as the not stopping goes, this may be the same problem that I
reported a week ago (look for software single step in the archives). 
With Daniel's assistance, I've been able to isolate the problem (same on
5.2 and 5.3), and I have a fix.  Once I've cleaned up and checked it,
I'll send an patch and an explanation to the list (replying to software
single step thread), hopefully I should get that done today.

Regards, Stuart
