| 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. |
