Ah yes, you are right. Compile the following snippet:
#define PORTA (*(volatile uint8_t *)0x3B)
static inline void __attribute__((always_inline))
toggle_pin(void)
{
PORTA |= 1;
PORTA &= ~1;
}
int
main(void)
{
toggle_pin();
return 0;
}
with these two commands:
avr-gcc -O0 -S foo.c # works correctly
avr-gcc -O0 -S -Dinline= foo.c # doesn't inline toggle_pin()

Never trust an operating system you don't have sources for. ;-)
