Hi All,
how you should know, I'm working to port OpenWRT on m68k/coldfire arch.
I compiled with success (and some patch) the toolchain... but I have
this error during the kernel build:
make[5]: Leaving directory
`/mnt/devel/openwrt/OpenWRT.git/build_dir/linux-cf547x/linux-2.6.23'

umoddi3 and udivdi3 are helper functions that support the long long
arithmetic. the libcc.a has these function:
$ m68k-linux-gnu-objdump -t libgcc.a
In archive libgcc.a:

I found the keyword ".hidden" placed before the symbols __umoddi3 and
__udivdi3 also on mipsel-compiled libgcc.a...
Any idea?
