Subject: Remove the unused MachineBasicBlock2IndexFunctor class.
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=3dfbb558b5e74554104710ed16807fe74ec220a3;p=oota-llvm.git

Remove the unused MachineBasicBlock2IndexFunctor class.
Move method bodies that depend on <algorithm> out of line to
MachineBasicBlock.cpp.  Patch contributed by Morten Ofstad!
