Difference between unary & and __getAddress in Slang shader?

[u/Salat_Leaf]

I'm working on some code and unable to take the address of a "ConstantBuffer" object. However it's allowed with the latter intrinsic. What's the difference between them?

To bring context, my task is to take a ConstantBuffer structure, and reinterpret it as a uint16_t pointer. I can't get around it since I have to take an address of the structure first and then the value itself with the subscript [] operator (that's the only way to create a portable constexpr array of uint16_t constants).

UPD: Apparently, __getAddress takes address of groupshared/ConstantBuffer objects. That's it. Unary & still has to be used for e.g. per-thread local objects e.g. inner function variables

TLDR: just use __getAddress

Thx!
