Hi !

I am new to this mailing list but I have already been working for
two years with avr-gcc on an ATMega103 (i am working in the framework
of a robotics club in order to participate in the 'e=m6' French Robotics
Cup - some of you might know it).

Some instructions do work only on registers above 15 (such as sbci, and
most of instructions with immediate values i guess). Therefore, I'd like
to know if there is a special constraint when writing inline assembler
to tell gcc to use registers above 15...
