// Test that the runtime correctly interposes atexit.
//
// REQUIRES: disabled
//   This test is disabled until a proper atexit interpose can be implemented:
//   the current one assumes that atexit is defined in the dylib that calls it,
//   which is not true in general. See
//   https://github.com/llvm/llvm-project/issues/74641.

// RUN: %clang -c -o %t %s
