3; Check that our compiler never emits global constructors
4; inside the .init_array section when building for a non-Linux ELF target.
5; Because of this, the test depends on UseInitArray behavior under FreeBSD
6; as found in Generic_ELF::addClangTargetOptions().
7
8; This is to workaround a Visual Studio bug which causes field
9; UseInitArray to be left uninitialized instead of being
10; zero-initialized (as specified in [dcl.init]p7).
11; This workaround consists in providing a user default constructor
12; that explicitly initializes field UseInitArray.
