Boah, workaround alert. Why do you not fix the compiler?
We need to copy from address 0 (that's where the lowcore resides).
But gcc
insists to complain if memcpy is used with src == NULL.. Now what?
Erm sorry, misread your question. Usually it's a bug to use memcpy with
src == NULL. In this case it's ok. So I think it's perfectly ok if gcc
emits a warning.
If you know of a better way to get around this please let me know.
-ffreestanding or -Wno-nonnull?
