Actually TargetMachine is pretty clean: only the getSchedInfo and
getRegInfo methods are sparc specific, and getSchedInfo is likely to be
refactored at some point to be more target specific (getRegInfo() is
already replaced by getRegisterInfo()).  Worse is TargetInstrInfo, which
has a large number of methods that are sparc specific (located under the
"WARNING: these methods are sparc specific" comment).
