METHOD AND APPARATUS FOR MOVING AREA OPERATOR DEFINITION INSTRUCTIONS STATEMENTS WITHIN CONTROL FLOW STRUCTURES

摘要

pA method and apparatus for use in compiling data for a program shader identifies within data representing control flow information an area operator definition instruction statement located outside the data dependent control flow structures. The method identifies within one of the data dependent branches at least one area operator use instruction statement that has the resultant of the area operator definition instruction statement as an operand. After identifying the area operator use instruction statement, the area operator definition instruction statement is placed within the data dependent branch./p[US2007180437A1]
