But I'd like the idea of it arriving intact in the move to compiler-rt.  If I'm able to get it back and running by the end of the week, would that be adequate?

Hi Brian,

Great, thanks!
I’m not sure why it’s not build: maybe because we never run “all” when LLVM_USE_SANITIZE_COVERAGE is set, which is required that to build that library.
