Find Unnecessary Includes

Definition: An #include directive is necessary if its removal will cause a compile error.

Definition: An #include directive is optional if its removal (and possibly accompanied by the addition of other #include directives) will not cause a compile error.

Given a C++ translation unit that successfully compiles, this tool lists necessary or optional #include directives in the main source file. Only #include directives in the main source file are considered. Nested #include directives are not considered.

Something went wrong with that request. Please try again.
