--- Comment #4 from Peter Bergner <bergner at gcc dot gnu.org> --- (In reply to Michael Meissner from comment #3) > The -mupper-regs-df and -mupper-regs-sf options are a work in progress. I > am working on these options right now on a private branch, but the code is > not yet ready for incorporation into the tree. I don't know how long it > will take to track down the various bugs before the patches are submitted. Meaning, don't use the -mupper-regs-df and -mupper-regs-sf options until Mike has his patch(es) upstream.
