|
; Check that our compiler never emits global constructors
|
|
; inside the .init_array section when building for a non-Linux ELF target.
|
|
; Because of this, the test depends on UseInitArray behavior under FreeBSD
|
|
; 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.
