CLang's optimizer is more aggressive at inlining functions than gcc and so will often inline functions that our tests want to mock-override. This causes the test to fail in bizarre ways. We don't want to disable inlining completely, but we must at least prevent inlining of mocked functions. Fortunately there is a 'noinline' attribute that lets us control this per function. A syntax check rule is added that parses tests/*mock.c to extract the list of functions that are mocked (restricted to names starting with 'vir' prefix). It then checks that src/*.h header file to ensure it has a 'ATTRIBUTE_NOINLINE' annotation. This should prevent use from bit-rotting in future. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
