Subject: DebugInfo: Require non-null in DIBuilder::retainType()
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=6ed3a762fcce2b4ac8f232cd61dd07ee807b2a59;p=oota-llvm.git

DebugInfo: Require non-null in DIBuilder::retainType()

Assert that a non-null value is being passed in.  Note that I fixed the
one offender in clang in r233443.
