Subject: Fix for machine licm assert: RCCost <= RegPressure[RCId]
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=dc986d2462ca8df72af9e2f6afac0ba86b753e5b;p=oota-llvm.git

Fix for machine licm assert: RCCost <= RegPressure[RCId]
in MultiSource/Benchmarks/VersaBench/beamformer/beamformer.
SmallSet.insert returns true if the element is inserted.
