llvm/compiler-rt/test/orc/TestCases/Darwin/x86-64/Inputs/dlopen-dlclose-x2.S

// Runs a sequence of dlopen, dlclose, dlopen, dlclose on a library "inits".
// This is intended as a standard harness for testing constructor / destructor
// behavior in the context of a full dlclose and then re-dlopen'ing of the
// inits library.
//
// Compiled from:
//
// int main(int argc, char *argv[]) {
//  printf("entering main\n");
//  void *H = dlopen("inits", 0);
//  if (!H) {
//    printf("failed\n");
//    return -1;
//  }
//  if (dlclose(H) == -1) {
//    printf("failed\n");
//    return -1;
//  }
//  H = dlopen("inits", 0);
//  if (!H) {
//    printf("failed\n");
//    return -1;
//  }
//  if (dlclose(H) == -1) {
//    printf("failed\n");
//    return -1;
//  }
//  printf("leaving main\n");
//  return 0;
//}
