摘要：
To provide a method for enabling a trace of a stack even without the base pointer. When compiling a subroutine, a stack pointer (SP) change table is created and registered with a subroutine together with an initial frame size, the table recording a pair of an address of a code and the amount of change in the stack pointer from the initial frame size, the code causing an address of the stack pointer to be changed, and a thread is caused to pause at a stack tracing time to calculate the be address of the frame from an address of the initial frame, an execution restarting address in this frame and the SP change table registered with a subroutine corresponding to this address and the initial frame size, and thus a trace of a stack is performed.
