Hi, To use the libgcc, we need to link the object file, this doesn't work in system that use non ELF format like mach-o. And actually, the int function rarely changed, and some project like openbios also include the libgcc function directly. -- Bean gitgrub home: http://github.com/grub/grub/ my fork page: http://github.com/bean123/grub/ _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
