[Lldb-commits] [lldb] r115249 - in /lldb/trunk/test/foundation: TestDisassemble.py main.m

New Revision: 115249

URL: http://llvm.org/viewvc/llvm-project?rev=115249&view=rev
Log:
Add a simple test for the lldb 'disassemble' command.  The initial version just
sets some breakpoints and invokes 'disassemble' when the breakpoint hits, which
just disassembles the bytes in the current function, i.e., frame #0's function.
