Expand description

Get the state of a specific barrier type.

The `barrier_type` argument must be uniform, otherwise behavior is undefined.

This intrinsic does not behave like a normal function call; it is a “convergent” operation and as such has non-standard control-flow effects which need special treatment by the language. Rust currently does not properly support convergent operations. This operation is hence provided on a best-effort basis. Using it may result in incorrect code under some circumstances.
