--- Comment #1 from Peter Bergner <bergner at gcc dot gnu.org> --- This seems somewhat related to PR24644 which was "fixed". That bug showed we do not want to copy global registers to other "tmp" registers and use them from the "tmp" reg. In this case, at least we're still using the global register, but it would be interesting to know how is creating those copies. Aaron, can you look thru the dump files to see where these are being generated?
