Abstract: Reducing live range of variables for register allocation of structured control-flow programs is provided. The method comprises defining an affine expression for each static single assignment (SSA) variable contained in an input program for a computer compiler. The affine expression of a SSA variable in the input program is derived by substitution of affine expressions of input operands involved in computation of the SSA variable.

The method identifies one or more overlapping dependence edges with a same source among the dependence edges and eliminates the longer of the overlapping dependence edges according to the derived affine expressions.
