Subject: Increase the initial vector size to be equivalent to the size of the Deps
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=b319f127274291a2f58e1f2a146f4e5a274f1e10;p=oota-llvm.git

Increase the initial vector size to be equivalent to the size of the Deps
vector. This potentially saves a resizing.
