Hello, I am a PhD student in Computer Science at UW Wisconsin Madison. I have been using gcc with the -fdump-rtl-expand-lineno and -fdump-tree-cfg-lineno flags for my research doing some static analysis of the linux kernel. I am in particular trying to parse inside line number pairs for loops and function calls/pointers. For loops I want to find the loop length/number of iterations or what the loop is dependent on. For function calls and pointers I want to follow the function calls recursively and repeat some of my static analysis along the full call stack. I am trying to find some flags that can give me more information than I have coming from the current flags (or maybe differently formatted info), but I am struggling to understand the flag options and dump formats. Even with the flags I am already using to some success I find myself struggling to understand the information already there, even with the existing documentation. Is there anyone who knows more about these flags and may be able to hear a bit more the info I am looking for and help point me in the right direction? Any pointers or suggestions would be really helpful. Thank you, Abby
