In compiler theory, a reaching definition for a given instruction is another instruction, the target variable of which may reach the given instruction without an intervening assignment. For example, in the following code:
d1 : y := 3 d2 : x := yd1 is a reaching definition at d2. In the following, example, however:
d1 is no longer a reaching definition at d3, because d2 kills its reach.

Famous quotes containing the words reaching and/or definition:
“And the ambitious vine
Crowns with his purple mass
The cedar reaching high
To kiss the sky,
The cypress, pine,
And useful sassafras.”
—Michael Drayton (1563–1631)
“According to our social pyramid, all men who feel displaced racially, culturally, and/or because of economic hardships will turn on those whom they feel they can order and humiliate, usually women, children, and animals—just as they have been ordered and humiliated by those privileged few who are in power. However, this definition does not explain why there are privileged men who behave this way toward women.”
—Ana Castillo (b. 1953)
