What does this diode do on pin#1 and Pin#8 on this Op-amp?

Mostly I see a capacitor on Pin#1 and Pin#8 for frequency compensation

Are they using the capacitance of the diode?

Take a look please

This circuit is possibly a comparator, cf. page 13 of the datasheet. It is very unlikely that they usewd the diode's capacitance as this would be rather unspecified, temperature dependent, voltage dependdent etc.

I also have never seen anything other than a cap in that position
