Computer-readable recording medium storing program for converting first single instruction multiple data (simd) command using first mask register into second simd command using second mask register, command conversion method for converting first simd command using first mask register into second simd command using second mask register, and command conversion apparatus for converting first simd command using first mask register into second simd command using second mask register

Abstract

A recording medium stores a program for causing a computer to execute a process including: converting, in a first source code corresponding to a first-type processor, a first load command for a first mask register included in the first-type processor into a second load command for a second mask register included in a second-type processor; and converting, when a first SIMD command for performing an arithmetic operation using the first mask register exists after the first load command in the first source code and a state of a value of the first mask register does not coincide with a state of a value of the first mask register, the first SIMD command into a second SIMD command corresponding to the second-type processor and a change command for changing a state of a value of the second mask register to a state of a value of the second mask register.
