Add a basic Function call tracer to LogMaker

[R3x]

Function call tracer

• [ ] Iterate through the entire program and get details on all the function calls
• [ ] Get function arguments for each call
• [ ] Sort whether each call is a library call or a user defined call
• [ ] Store addresses of each function call
• [ ] Store statistics of each function call (ie how many times is it called)
• [ ] Sort function calls - by callee functions
• [ ] Mark out common arguments for multiple functions - (It can help us figure out some pattern)
