Subject: Remove the TargetMachine from DFAPacketizer since it was only
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2a321f74f0ac27f98ba98e6bcd326acf6907f9db;p=platform%2Fupstream%2Fllvm.git

Remove the TargetMachine from DFAPacketizer since it was only
being used to grab subtarget specific things that we can grab
from the MachineFunction anyhow.
