New Revision: 211811
URL: http://llvm.org/viewvc/llvm-project?rev=211811&view=rev
Log:
Move the various Subtarget dependent members down to the subtarget
for the Sparc port. Use the same initializeSubtargetDependencies
function to handle initialization similar to the other ports to
handle dependencies.
