Not as far as I know.

Well, the current scheme uses the gas frag structure to store the
source lines as well as the generated code.  The problem is that each
line generates a new frag, and breaking up the generated code
occasionally turns off some optimisations.  You'd need a scheme that
stored multiple source lines within one frag.  Shouldn't be too hard.
