◆ depends()

depends - Tests for a dependence between the Src and Dst instructions.

Returns NULL if no dependence; otherwise, returns a Dependence (or a FullDependence) with as much information as can be gleaned. By default, the dependence test collects a set of runtime assumptions that cannot be solved at compilation time. By default UnderRuntimeAssumptions is false for a safe approximation of the dependence relation that does not require runtime checks.
