The following describes three kinds of data dependence. The notation
S1, S2, and SN is used to denote statement
1, statement 2, and statement N, respectively. In each example,
S2 is dependent on S1 , due to variable
x .
(S1): x = 3; (S2): y = x;
(S1): y = x; (S2): x = 3;
(S1): x = 3;
:
(SN): x = 4;
