New Revision: 142710

URL: http://llvm.org/viewvc/llvm-project?rev=142710&view=rev
Log:
Add "display" and "undisplay" aliases for target stop-hook add/delete.
A patina of gdb's "display" command, intended mostly for simply monitoring
a variable as you step through source code.  Formatters do not work, e.g.
display/x $pc does not work.
