--- Comment #1 from Richard Earnshaw <rearnsha at gcc dot gnu.org> ---
Confirmed.  Prologue and epilogue code is constructed in the backend late on. 
Any optimizations have to be done during the code generation.  The particular
path with -fomit-frame-pointer is not on by default and clearly hasn't been
tuned yet.
