In Pintool, How to find the name of an routine's caller?

Question

I want to trace the mutex variables in my rust program(e.g. which mutex called lock() and unlock() methods). And I think there're static methods.

Answer 1

In instruction instrumentation function, you can check if the instruction is indeed a call instruction. Something like -

if (INS_IsCall(ins))
    {
        if (INS_IsDirectCall(ins))
        {

Then get the name of the routine:

if (RTN_FindNameByAddress(INS_DirectBranchOrCallTargetAddress(ins)) 
== "yourfavouritefun")
do something;
        }
}

And you can obviously log the caller.

VOID Instruction(INS ins, VOID *v) {
ADDRINT insaddress = INS_Address(ins);
if (RTN_FindNameByAddress(insaddress))
  do something more;
