create_new_frame() on Linux/IA64

[Johan Walles]

I'm trying to insert artificial stack frames in a backtrace using 
create_new_frame(addr, pc) on Linux/IA64.  The pc parameter is quite 
obvious, but what should I use for addr?

The problem I'm trying to solve is that we do our own code generation, 
and gdb can't parse our stack frames.  I'm trying to patch 
get_prev_frame() to call on us for help with stack frames it doesn't 
recognize.
