How to analyse lock acquire and release using intel pin instrumentation - How to analyse lock acquire and release using intel pin instrumentation
I am analyzing C++ codes to find data races in them using intel pin Now I found some inbuilt functions in Intel Pin like INS_IsMemoryRead and INS_IsMemoryWrite to determine if a instruction is memory read or write respectively Now I want to achive the same for lock acquire and lock release (only for C++ pthread_mutex) but I didn't find any such function So I disassembled the lock acquire statement and found a lock prefix and a cmpxchg statement So I decided to use lockPrefix function of Intel Pin to determine if the instruction has lock prefix and INS_Opcode function to check if xed value is cmpxchg and then check if the adress being written to has value 1 then we can say lock acquire is successful But I believe there is something simpler and also have doubts regarding correctness of my approach

I am really sorry but I don't understand what you mean by "FPGA question"
