Subject: Windows gdb: Enable "set scheduler-locking on"
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b36c26b485d3fe9e50ace0605a2ed7bb3a6c8a31;p=thirdparty%2Fbinutils-gdb.git

Windows gdb: Enable "set scheduler-locking on"

Surprisingly (to me), enabling scheduler locking on Windows currently
fails:

 (gdb)
 set scheduler-locking on
 Target 'native' cannot support this command.

The backend itself does support scheduler-locking.  This patch
implements windows_nat_target::get_thread_control_capabilities so that
the core knows schedlocking works for this target.
