Duncan,
Is this expected for x86_64-apple-darwin12 under Xcode 5? Using current
llvm/compiler-rt/clang/polly/testsuite with dragonegg 3.4 branch, I see
the warnings...

'-cmpxchg16b' is not a recognized feature for this target (ignoring

'-cmpxchg16b' is not a recognized feature for this target (ignoring

Are these warnings for...
'-cmpxchg16b' is not a recognized feature for this target (ignoring
feature)
expected? The resulting executable runs fine but I don't recall seeing this
warning before.

The resulting executable runs fine but I don't recall seeing this warning before.The cmpxchg16b feature was renamed to cx16 in LLVM. I've made the corresponding change to DragonEgg in r195404.
