Subject: DWARF emission: Remove unnecessary/redundant DIE reference code
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=9e39e0d56d105f97b9d8f851403619bb0d9f780d;p=oota-llvm.git

DWARF emission: Remove unnecessary/redundant DIE reference code

The default case at the end of the switch handles this just fine.
