I'm sure you have done the research on why the existing arguments
against providing libatomic are wrong. For some reasons, you have missed
including them in your email.

LLDB doesn't need libatomic. It needs a patch to fix the timer
implementation to not require 64bit atomics. Which is exactly one of the
original points that libatomic hides major performance issues and
amusingly in this case, even in time sensitive code.
