[llvm-dev] How to check if a variable is updated inside a loop?

[karan raj singh ranawat via llvm-dev]

If there is a variable outside a loop, and if it is used inside a loop. How
can I check in the LLVM analysis if the variable is getting modified inside
a loop iteration.
Ex: int i = 0;
for(;;i++){}When there is i++, the load instruction updates existing i. How
can I identify if the load instruction is part of a loop.
