avr-gcc crashes with an internal compiler error when shift operations with
negative shift count are used, e.g. a >> -13. Error message is "negative
instruction length", probably since the expression used for calculating the
instruction length (c-code) assumes the shift count to be a positive number.
Test cases known to fail are, e.g. .
gcc.c-torture/compile/20020710-1
20021119-1
20021123-4
920626-1
930621-1
Problem is present in 4.0 and I expect it to exist in all the previous
releases. (compare the test report in [EMAIL PROTECTED]
