Dear developers, Thank you to all developers who give me feedback. I will continue to search based on your suggestions. If you know of other published projects which used static pointer analysis through Dyninst on x86/64 binary, please let me know. I appreciate it.

This isn't my area of expertise, but I believe using dataflow analysis would be a place to start. DataflowAPI won't have a single method to solve pointer aliasing because it's too complex of a problem, but the information it provides should get you started. Feel free to ask more questions here or open a question issue on our Github. Thanks. - Tim On 12/12/22 3:37 PM, Wen Zhang wrote: Dear developers, I am using Dyninst to do the static binary analysis on x86/64. And I meet one problem with how to use Dyninst to identify two memory locations represented by different registers that may point to the same memory location. For example, there are two assembly codes: mov %rax, 0x8(%rbp) mov %rcx, 0x4(%rcx) Even though these two memory writings look totally different, 0x8(%rbp) and 0x4(%rcx) may point to the same memory location. I have looked at all manuals in Dyininst, but it seems nothing related to this problem. Is there any API or method given by Dyninst that can solve this problem? I appreciate your feedback.
