------- Comment #10 from pinskia at gcc dot gnu dot org 2008-01-22 20:24 -------
Even though it has not been said here yet, the way to fix this is to have
lmw/stmw emitted for r30/r31. Though this only saves 8 bytes per function.
It is the only fix which will help. It does not fix the "regression" as it is
not really a regression anymore.
