antidependence and data hazard

See below example.

        ADDD  F6, F0, F8

        SUBD   F8, F10, F14

Some article would say that “ There’s an antidependence between ADDD and SUBD…”.

This statement certainly looks confusing because “anti” means opposite, and obviously there’s dependency between ADDD and SUBD by F8.

The truth is, though, the term “antidependence” is a misnomer. The correct term is “ante”, which means before.

The correct statement should be “There’s an antedependence between ADDD and SUBD”, which means there’s dependence between ADDD and SUBD and ADDD should be ahead of SUBD.

If SUBD is ahead of ADDD, then there may be a WAR hazard.
