Hello,, I am new to all this,, And i have some questions i hope i can find answers for in here!! any answer is appreciated, please answer whatever question you know the answer to!!

1st, how is xmm0 different for every address ? is it static among all addresses or it changes for avery app or what ?

2nd, i need to multiply the value of xmm0 before i do a "movq [###], xmm0", i need for example to multiply it by 5.00, What is the statement for doing that ? (Note: multiply by a double value)

3rd, Can i search the memory view for a specific xmm0 value ? and find the code the address that holds that xmm0

4th, Can i find out the chain of commands that a certain address or register has passed through ?? from its creation until its last edit!

finally, is there a good tutorial tutorial for how to navigate in the memory view and understand it ??
