New Revision: 172882
URL: http://llvm.org/viewvc/llvm-project?rev=172882&view=rev
Log:
This is a resubmittal. For some reason it broke the bots yesterday
but I cannot reproduce the problem and have scrubed my sources and
even tested with llvm-lit -v --vg.
Formatting fixes. Mostly long lines and
blank spaces at end of lines.
