-  /* Normally signal frames are detected via amd64fbsd_sigtramp_p.
-     However, FreeBSD 9.2 through 10.1 do not include the page holding
-     the signal code in core dumps.  These releases do provide a
-     kern.proc.sigtramp.<pid> sysctl that returns the location of the
-     signal trampoline for a running process.  We fetch the location
-     of the current (gdb) process and use this to identify signal
-     frames in core dumps from these releases.  Note that this only
-     works for core dumps of 64-bit (FreeBSD/amd64) processes and does
-     not handle core dumps of 32-bit (FreeBSD/i386) processes.  */
