Subject: Fix for PR26690
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d58b976bb7a38fa438c06782827d25d266af81e5;p=platform%2Fupstream%2Fllvm.git

Fix for PR26690

I mistook BitVector::empty() to mean BitVector::count() == 0 and it does
not. Corrected the issue with the fix for PR26500.
