// Test, using compiler diagnostic flags, that inlining of functions
// imported from the sync package is working.
// Compiles but does not run.
// FIXME: This test is disabled on architectures where atomic operations
// are function calls rather than intrinsics, since this prevents inlining
// of the sync fast paths. This test should be re-enabled once the problem
// is solved.
