Subject: Remove the default constructor and count variable from the Mangler since
X-Git-Tag: llvmorg-4.0.0-rc1~8661
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1c3bb79864f45bd3c6dfc1563d72a2eb89f03a3a;p=platform%2Fupstream%2Fllvm.git

Remove the default constructor and count variable from the Mangler since
we can just use the size of the DenseMap as a unique counter.
