--- Comment #61 from Jack Howarth <howarth at nitro dot med.uc.edu> 2011-02-05 19:04:18 UTC --- Actually the two issues are entirely intertwined. PR47558 was due to not prioritizing symbols from libSystem over those from libgcc_ext. FYI, I don't see why getting ___divdc3 fixed in time for Lion should be that difficult. Since this issue is in the compiler-rt open source project, I'm sure the linux users of llvm would not be happy to see their math routines degraded.
