3// Test active mask synthesis for a `switch` statement
4// that exhibits "trivial fall-through" from one `case`
5// to another.
6
7// We've ended up having to disable this test everywhere,
8// which really speaks to the way that the "active mask" concept
9// in D3D and Vulkan was never really specified to a level
10// that makes it meaningful.
11//
12// Even if the specs get fixed at some point down the line,
13// we can't really re-enable these tests because they'd fail on way
14// too many GPUs and driver versions.
