// NOTE: Assertions have been autogenerated by utils/update_cc_test_checks.py
// REQUIRES: native, target=powerpc64-{{.*}}
// The stdlib.h included in mm_malloc.h references native system header
// like: bits/libc-header-start.h or features.h, cross-compile it may
// require installing target headers in build env, otherwise expecting
// failures. So this test will focus on native build only.
