Subject: Always create a shadow node for a store instruction, even if it's storing
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=eef796c767407aff5f29bd061a58c99b9b97927b;p=oota-llvm.git

Always create a shadow node for a store instruction, even if it's storing
a scalar value.  Likewise for load instructions.
