Subject: Don't print the debug directory; it's often long and uninteresting. Omit
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=4b808b014b0cd25261f93e1885ffdbd0247d8634;p=oota-llvm.git

Don't print the debug directory; it's often long and uninteresting. Omit
the column number if it is not known. Handle the case of a missing filename
better.
