Subject: gdbserver: use current_process in ps_getpid
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c0cb02a4cf590f3cb64cdcc1b5bf539196333160;p=binutils-gdb.git

gdbserver: use current_process in ps_getpid

The following patch ("gdbserver: switch to right process in
find_one_thread") makes it so find_one_thread calls into libthread_db
with a current process but no current thread.  This tripped on ps_getpid
using current_thread in order to get the process' pid.  Get the pid from
`current_process ()` instead, which removes the need to have a current
thread.  Eventually, it would be good to get it from the
gdb_ps_prochandle_t structure, to avoid the need for a current process
as well.
