No, you don't want this, because the same translated code may be invoked multiple times with different values in registers. > example, the tb has an instruction of mov 0x4(%ebx) %eax. > To calculate the address of 0x4(%ebx), I need to know the value of %ebx. > Is this correct? Thanks. Why don't you just instrument actual memory access functions in softmmu_template.h ? -- Thanks. -- Max
