--- Comment #39 from Alexandre Oliva <aoliva at gcc dot gnu.org> ---
At least the sparc regression was caused by the change richi requested to
disregard the underlying decl in promote_ssa_mode. I didn't realize this could
cause a mismatch between the mode of the partition created for the QImode parm
default def and the promoted mode for the parm decl expected by the
parm-assignment code in function.c. This will likely take some time to sort
out, so I'm reverting the patch for now.
