Hi Eric,

I recently added the function smbus_write_byte() to 
src/southbridge/amd/amd8111/amd8111_early_smbus.c. 
if the code within #if 0 in that function is enabled, I get the
following internal compiler error:

./romcc -mcpu=k8  -O ./auto.E > auto.inc

Is the code running out of registers? What's happening here?
