Subject: Increase inliner thresholds by 25.
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=f9c3b228e5579e0d2a9cd05a2191fe17b4c58b23;p=oota-llvm.git

Increase inliner thresholds by 25.

This makes the inliner about as agressive as it was before my changes to the
inliner cost calculations. These levels give the same performance and slightly
smaller code than before.
