METHOD FOR LINEARIZING NONLINEAR INDEX EXPRESSION BASED ON VALUE PROFILE

摘要

PROBLEM TO BE SOLVED: To improve the applicability of the optimization of a loop including an array reference having a nonlinear index expression.;SOLUTION: By this linearizing method, a language processing system 20 adds a value profile acquisition code of a variable as a nonlinear coefficient in some nonlinear index expression in some array having values set in a loop of a source program 10 to the source program 10, finds a nonlinear coefficient value profile 60 obtained by executing an object program generated from the source program, and uses the profile to linearlize the nonlinear index expression in the loop of the source program 10.;COPYRIGHT: (C)2000,JPO
