Dear Sir,
Thank you very much. I will look in depth and raise the question if I get.
If theread support is disabled, then also gdb server side does the
symbolic address finding ? I think not, am I right ? please clarify me.
How can I get all the gdb mailing list into my inbox ? like rtems.
Regards
Raja Saleru

If you look at the linuxthreads_db/ directory in glibc source, you'll
see the trick - thread_db_init calls back into the application. Take a
look at gdbserver/proc-service.c, function ps_pglobal_lookup.
