<p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'>This
predicate doesn't make much sense inside of LLVM currently because all of the
backends track 64-bitness separately for some (likely historical) reason.
However, Clang could benefit greatly from this predicate, it would remove one
of the most commonly repeated queries about a triple. It also seems likely that
targets could move toward relying more heavily on the triple to deduce these
things, or at least start asserting that the explicit 64-bitness of the
subtarget objects matches the triple.<o:p></o:p></span></p>
