[Lldb-commits] [PATCH] Allow specification of no source display on stop

[Randy Smith]

Based on r212225.  I've sketched out my rationale for this change in
http://llvm.org/bugs/show_bug.cgi?id=20149.  It's fairly simple; is someone
willing to take a look?

Note that I don't (yet) have commit access, so if this patch is approved
someone will need to land it for me.  (I found the LLVM and LLDB pages not
completely consistent around the process for gaining commit access, so I'm
going with the LLVM "contribute several patches and then ask".)

I ran the "check-lldb" test suite on Linux, and found no difference in
results between r212225 and r212225+my patch.  (As a side note, what should
I expect from the Linux test suite?  TestConvenienceVariables.py is failing
for me at top of tree.)
