Subject: Move the N->use_empty() assert from DeleteNode to
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=e77f89de8cb6690ac45b87b03c588e9d287c1eeb;p=oota-llvm.git

Move the N->use_empty() assert from DeleteNode to
DeleteNodeNotInCSEMaps, since DeleteNode just calls
DeleteNodeNotInCSEMaps.
