Subject: Experiment with printing a warning message when lldb is unable to
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=56c23285f938949819bde377726f867a7d9bcfbb;p=platform%2Fupstream%2Fllvm.git

Experiment with printing a warning message when lldb is unable to
find a binary on the debugger-host during a kernel debug session
for a kernel extension (kext).  This may prove to be too verbose
in typical usage, particularly if there are many third-party kexts.
We'll try this and see how it works.
