Subject: Upreferences are always OpaqueTypes, meaning that it is impossible for a non-abstract
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=2c37c18c6e9f5f2b898ac410da5306614a4db5c0;p=oota-llvm.git

Upreferences are always OpaqueTypes, meaning that it is impossible for a non-abstract
type from containing one.  This speeds up the asmparser on the testcase in PR224 from
61->50s.
