3// This test tries to ensure that a `row_major` layout default specified on
4// the command line makes it through to affect code generation on all targets.
5// The test was created because it was found that released versions of dxc
6// were ignoring the `#pragma pack_matrix` directive.

8// This has a compatibility issue on Windows 10.0.10586 on Dx12 - dxcompiler will crash (can remove form tests with -exclude compatibility-issue)
