I don't think this is true for all languages targeting AMDGPU. For example, HIP has APIs like `hipMemcpyToSymbol` which accept a string identifying a symbol for a variable in global/constant address space. @yaxunl is my understanding about the HIP runtime requiring dynamic symbols for global variables correct here?
