Abstract: PROBLEM TO BE SOLVED: To provide a method for ensuring that a line is present in an instruction cache by instructing a computing system. SOLUTION: In the method for ensuring that the line is present in the instruction cache by instructing the computing system, a line-touch instruction is selected, the line-touch instruction is recognized as one type of a branch instruction which does not branch, the line-touch instruction is executed to fetch a target line from a target address into the instruction cache, and execution of the line-touch instruction is interlocked by completion of the fetch of the target line for preventing execution of an instruction following the line-touch instruction until the target line reaches the cache.
