-- SPIR-V extension, which allows shaders to explicitly define the layout
-- of @Workgroup@ storage class memory and create aliases between variables
-- from that storage class in a compute shader.
--
-- The aliasing feature allows different “views” on the same data, so the
-- shader can bulk copy data from another storage class using one type
-- (e.g. an array of large vectors), and then use the data with a more
-- specific type. It also enables reducing the amount of workgroup memory
-- consumed by allowing the shader to alias data whose lifetimes do not
-- overlap.
--
-- The explicit layout support and some form of aliasing is also required
-- for layering OpenCL on top of Vulkan.
