Subject: Make AsmPrinter::EmitTTypeReference() more robust - put
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=097b0e9d6a8f2499617fe11059bdfbd7e136ad28;p=platform%2Fupstream%2Fllvm.git

Make AsmPrinter::EmitTTypeReference() more robust - put
the zero GV check inside, so we won't forget it at the caller side.
