Hi,
here is the changed patch for avr.c . I hope that it is now compliant to the
gcc coding standards. I however did not understand what you have meant with
"this hunk adds spurious whitespace".

Never mind, as it's likely not worth the bother as the behavor
is undefined anyway, and the existing proposal is simpler.

Actually wonder if a better solutions would be to and (&) the rhs shift count by
Log2(rhs-mode-size) bit mask, thereby the resulting value will always be within
0 >= shift <= (N-1), resulting effectivly a shift m

Hi,
I have just stepped over a patch suggested by Bernardo Innocenti in order to
treat the case of "shift_count == 0" correctly. My presently suggested
patch (above) only treats the case of negati

If it would be OK for GCC to simply ignore negative constant shift counts,
the following patch would do. I have tested this with the test suite for
gcc-3.4.3 . Unfortunately avr-gcc is still broken o

It seems that the standard says that shift operations with negative shift count
