Subject: Centralize thread ID printing
X-Git-Url: http://git.efficios.com/?a=commitdiff_plain;h=43792cf0de3a49fb871d432343672bdf16270e99;p=deliverable%2Fbinutils-gdb.git

Centralize thread ID printing

Add a new function to print a thread ID, in the style of paddress,
plongest, etc. and adjust all CLI-reachable paths to use it.

This gives us a single place to tweak to print inferior-qualified
thread IDs later:

 - [Switching to thread 1 (Thread 0x7ffff7fc2740 (LWP 8155))]
 + [Switching to thread 1.1 (Thread 0x7ffff7fc2740 (LWP 8155))]

etc., though for now, this has no user-visible change.

No regressions on x86_64 Fedora 20.

gdb/ChangeLog:
2016-01-13  Pedro Alves  <palves@redhat.com>

	* breakpoint.c (remove_threaded_breakpoints)
	(print_one_breakpoint_location): Use print_thread_id.
