Dmitry has taken responsibility for the math library code in avr-libc. I don't think he'll be able to tell you much about GCC's code generation... Regarding your bit test pessimizations, it might be worth opening a GCC bug report, but still, it would need some GCC developer to track that down, and eventually fix it... For the time being, I've seen better results by turning bit tests into inline functions (return type "bool"). -- cheers, J"org .-.-. --... ...-- -.. .
