[Lldb-commits] [lldb] r233236 - Add a test to make sure if you do:

New Revision: 233236

URL: http://llvm.org/viewvc/llvm-project?rev=233236&view=rev
Log:
Add a test to make sure if you do:

% lldb /bin/echo
(lldb) r 1 2 3
(lldb) r 

You get "1", "2", and "3" as arguments in the next re-run when no args are specified. This is behavior we do to match what GDB did and we need to test that we don't regress on it.
