I have following code ,and I can not understand the mark line,who can tell me.thanks.
00000ec7xorl 0x400dec(,%eax,4),%ecx ????<-----------------What it to do.
extern u_int32_t eax;
extern u_int32_t ecx;
{
u_int32_t *ptr;
ptr = (u_int32_t *)((eax * 4) + 0x400dec);
ecx ^= *ptr;
}Commonly used in the above form (with a fixed displacement) to access a 32bit value within an array of 32bit values.
The array start offset would be hardwired at 0x400dec, the zero based index into the array is provided by eax.
