Juergen Ributzka 8a4f2500be [TLI] Add a new hook to TargetLowering to query the target if a load of a constant should be converted to simply the constant itself. ... Before this patch we used getIntImmCost from TargetTransformInfo to determine if a load of a constant should be converted to just a constant, but the threshold for this was set to an arbitrary value. This value works well for the two targets (X86 and ARM) that implement this target-hook, but it isn't target-independent at all. Now targets have the possibility to decide directly if this optimization should be performed. The default value is set to false to preserve the current behavior. The target hook has been moved to TargetLowering, which removed the last use and need of TargetTransformInfo in SelectionDAG. llvm-svn: 200271		2014-01-28 01:20:14 +00:00
