[llvm-dev] Dependency Info from AST

[Siddharth Shankar Swain via llvm-dev]

Hi,
Can anyone help if for example we have multiple c files and we want to
analyze their ASTs to find out any dependency between them ( like a
function defined in one c file is used in other, any external variable etc
). How can we do it at the AST level? I mean is there any automated tool or
flag for it in LLVM. If anyone has any idea please tell.
sincerely,
Siddharth
