Subject: * Passes return true if they change something, not if they fail
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=6db0f4795cbd9b58add13c2b2f0c7124112ab9b7;p=oota-llvm.git

* Passes return true if they change something, not if they fail
* Convert opt to use Pass's and convert optimizations to pass structure
