Subject: Prevent use of the implicit copy constructor on SmallPtrSetImpl. An accidental copy... 
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=25fc910167b86a517628a64742f2555a3b05bd9e;p=oota-llvm.git

Prevent use of the implicit copy constructor on SmallPtrSetImpl. An accidental copy caused my SmallPtrSet->SmallPtrSetImpl conversion commit to fail the other day.
