Author: jhibbits Date: Sat Feb 9 21:08:19 2019 New Revision: 343943 URL: https://svnweb.freebsd.org/changeset/base/343943 Log: ddb: Print the thread's pcb in 'show thread' This can aid with debugging when a thread is running and has no backtrace. State can be estimated based on the pcb, and refined from there, for example, to get a rough idea of the stack pointer.
