get optimization level at compile time

[Johanan]

Hi,

Is there a way to know optimization level at compile time (STM32)? for example:

//————————————-

void _delay_us_x(int dly)
{
while (dly–)
__NOP();
}

#if  (_OPTIMIZE_LEVEL_  ==  0)

#define delay_us(x) _delay_us_x(x*4)

#else

#define delay_us(x) _delay_us_x(x*8)

#endif

//——————————————

Thanks
