I've added a comment on top of the function:
```cpp
// In HIP, dynamic LDS variables are represented using 0-element global arrays
// in the __shared__ language address-space.
//
// extern __shared__ int LDS[];
//
// These are not representable in SPIRV directly.
// To represent them, for AMD, we use an array with UINT32_MAX-elements.
// These are reverse translated to 0-element arrays.
