On the optimization side, profile guided opts are currently somewhat
limited. However, a couple of folks are actively working in this
area.<br>
<br>
All of the runtime support (i.e. recompiling, linking, etc..) is out
of scope for LLVM. Since this is the majority of the work required
to support PGO in a JIT, that's probably your answer.<br>
<br>
p.s. I'm answering what I *think* your question was. If this
doesn't help, you'll need to clarify your question.<br>

Hi <br>
Does current llvm support dynamic optimization level for
generated llvm IR which means , is it possible to monitor some
function's execution pattern during the runtime and apply
different optimization level for particular function using
