; Check that our compiler never emits global constructors
; inside the .init_array section when building for a non supported target.
; Because of this, the test depends on UseInitArray behavior under NetBSD
; as found in Generic_ELF::addClangTargetOptions().

; This is to workaround a Visual Studio bug which causes field
; UseInitArray to be left uninitialized instead of being 
; zero-initialized (as specified in [dcl.init]p7).
; This workaround consists in providing a user default constructor
; that explicitly initializes field UseInitArray.
