Re: [RFA] remote.c: adjust Z packet addr using BREAKPOINT_FROM_PC

[David Smith <dsmith at redhat dot com>]

I'm not exactly sure what you are trying to do here, but Kevin Buettner
posted a patch (that never got committed) that added a new architecture
feature that explicitly adjusted a breakpoint address (if necessary). 
You might look at it for ideas if nothing else.  The nice thing about it
is that the address "swizzling" is very explicit.  Here's a link:

<http://sources.redhat.com/ml/gdb-patches/2000-06/msg00257.html>

I hope this helps.
