The way libgcc functions are used depends on compiler optimizations ans isn't guaranteed to stay stable over minor versions (or even different compiler switches). > I.e.

The design bug is that the kernel provides only a (now insufficient) subset of libgcc. For some architectures, that is -- others have already __udivdi3 implementations.
