WebIt doesn't look like an issue: UMULL rdlo, rdhi, rn, rm rdlo and rdhi really must be different, but they are. Maybe CodeSourcery's toolchain is complaining about r0 appearing twice (as rdlo and rn) but that's not really an issue. We can multipply r0 and r3 and place the result in r0 and r1. Most likely to be gcc bug (or codesourcery's).
