New Revision: 208726
URL: http://llvm.org/viewvc/llvm-project?rev=208726&view=rev
Log:
Save the optimization level the subtarget was created with in a
member variable and sink the initialization of crbits into the
subtarget feature reset code.
No functional change, but this refactor will be used in a future
commit.
