I have a set of equations in string format as given below. Need to assign some value to the left-hand side variable (In the below example: rsp, esp). Then have to calculate and store the results on the right-hand side variable (i.e., rax, esp, rsp).

Example:

rax = rsp

esp = esp - 0x4

rsp = rsp - 0x30

Though I have used the eval function in python, it is throwing me an error message as it won't support =. Could someone please help me to find the answer?

    The answers to this question are not quick and easy. Time to read up on abstract syntax trees, parsers, and interpreters. I have a reading list on my website: msreverseengineering.com/program-analysis-reading-list You can expect to spend at least weeks studying these subjects before you feel comfortable doing what your question asks.
