Subject: Add a default constructor for LiveRange.
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=2319a2397990c6ae638b79efd43f88135db66d7b;p=oota-llvm.git

Add a default constructor for LiveRange.

It is useful to be able to create temporary LiveRange object whose
members are filled in later.
