// Test that unprofiled files are recognized. Here, we have two functions in the
// profile, main() and function_in_header, but we use the profile on a file that
// has the profile-less some_unprofiled_function so that the only profiled code
// in #included in a header.

// FIXME: It would be nice to use -verify here instead of FileCheck, but -verify
// doesn't play well with warnings that have no line number.
