Subject: Redirect DataLayout from TargetMachine to Module in SelectionDAG
X-Git-Url: http://plrg.eecs.uci.edu/git/?p=oota-llvm.git;a=commitdiff_plain;h=298a718c94bad00f580ddd4cb4fec5d218053f86

Redirect DataLayout from TargetMachine to Module in SelectionDAG

Summary:
SelectionDAG itself is not invoking directly the DataLayout in the
TargetMachine, but the "TargetLowering" class is still using it. I'll
address it in a following commit.

This change is part of a series of commits dedicated to have a single
DataLayout during compilation by using always the one owned by the
module.
