RE: [avr-gcc-list] On getting an ISR leaner with GCC
If you look in the avr-libc manual under Frequently Asked Questions you can find FAQ #3: How to permanently bind a variable to a register. That allows you to assign particular registers to variables, although care must be used when using the avr-libc library functions. I had faced a similar situation and some time ago I posted a query for a similar problem. The manual mentions a single register binding and in some cases a pointer may (two registers) may be required for binding and the manual does not talk about such binding. Now that this topic is being discussed, I was wondering if I can solve my problem!! Thank you. P.

I'd be quite suprised if the solution wasn't just to remove -lgcc from the link command and find out there weren't actually any uses of the code in libgcc.a That would also explain why there were no previous compilation errors, because the libgcc headers aren't there either, am I right Joerg Eric?
