Subject: Switch LoopIdiom pass to directly require target transform information.
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;ds=sidebyside;h=d12aae6c0535bd2713207ef84b7098f905a89b78;p=oota-llvm.git

Switch LoopIdiom pass to directly require target transform information.

I'm sorry for duplicating bad style here, but I wanted to keep
consistency. I've pinged the code review thread where this style was
reviewed and changes were requested.
