Subject: Pacify the compiler.  BestWeight cannot in fact be used uninitialized
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=2aea490e163b53e966d693285c17c1a934db5e8d;p=oota-llvm.git

Pacify the compiler.  BestWeight cannot in fact be used uninitialized
in this function, but the compiler was warning that it might be when
doing a release build.
