--- Comment #11 from howarth at bromo dot med.uc.edu --- FYI, the darwin linker developer had the following comments on @GOTOFF.. > This may be a red herring. > > @GOTOFF is a different concept. IIRC, the ELF runtime sets of RBX to point > to the GOT table. @GOTOFF is for accessing variables that are a (link time) > fixed offset in the GOT table. > > Darwin does not support @GOTOFF at all. Local variables are accessed > RIP-rel, or if large, indirectly via @GOT. However, outside of the sections of gcc/config/i386/i386.[c/md] conditional on HAVE_AS_GOTOFF_IN_DATA, I don't see any other obvious places where %rip would be emitted for Mach-O but not linux.
