| ; 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. |
