Follow-up Comment #4, bug #36611 (project avr-libc):
I ran into this problem and just re-wrote the *__delay_loop_2_* assembly.
This should be equivalent for all AVRs. It should even take the same number of
clock cycles (since *_sbiw_* takes 2 clock cycles).
My initial tests suggest this is working. Since *___count_* is a 2 byte
number, *_%A0_* and *_%B0_* should always work as expected.
void
_delay_loop_2(uint16_t __count)
{
__asm__ volatile (
"1: subi %A0,1" "\n\t"
"sbci %B0,0" "\n\t"
"brne 1b"
: "=d" (__count)
: "0" (__count)
);
}
