Subject: Eliminate the TopLevelManagerType enum; instead, just make
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=7578ea887de6a7cb22c324b629101683a0afb3c5;p=oota-llvm.git

Eliminate the TopLevelManagerType enum; instead, just make
PMTopLevelManager's constructor take a PMDataManager *, which already
provides the needed abstraction support.
