Hi Daisuke,
I create a new option "-tT" for gcore, so that it could display bt for user
space
directly inside crash itself, without needing to dump a separated core file
image,
and analyze it in a different gdb env.
The attached patch is directly based on below patch, and verify over ARM
platform.

Before use the corresponding gcore command, we need set env in crash by:
crash>> gdb set solib-search-path [system lib path]
crash>> gdb file [user space program symbol file]
crash>> gcore -t [user space thread id]
Thanks,
Lei
Hello Lei,
That must be a useful feature, but I think it's very othogonal to
gcore command...
Why not releasing your own extension module separately to gcore?
Thanks.
HATAYAMA, Daisuke
