Subject: if we have a phi translation failure of the start block,
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=3af23f8aba9ac28fe5a8646f57c2c307a35c1e4d;p=oota-llvm.git

if we have a phi translation failure of the start block,
return *just* a clobber of the start block, not other
random stuff as well.
