into the MC layer.
This is the sort of API that I was imagining:
void MoveAndEmitFragment(SmallVectorImpl<char> &&Data,
SmallVectorImpl<MCFixup> &&Fixups);
Note that this mirrors the fields
MCEncodedFragmentWithContents::Contents and MCEncodedFragmentWithFixups::Fixups
and the arguments could be directly moved into the fields of a newly created
MCDataFragment.
Would that work for your use case?

Just in case it interests anyone else, I'm playing around with trying to
broaden the MCStreamer API to allow for emission of bytes without copying
the contents into a local buffer first (either because you already have a
buffer, or the bytes are already present in another file, etc) in
http://reviews.llvm.org/D17694 . In theory there's some overlap with lld
here (no doubt it already does
