llvm generates additional information for kernels by creating structs on the device side named ` xxxx_kernel_environment` which are created as `weak_odr protected` . When calling spirv-link this symbols become "internal" and not exported in the final ELF image. Thus, the RTL cannot find them when running the binary.
A possible solution to this issue is to pass the ` --create-library` flang to `spirv-link`.
A test that exhibits this problem is ` offload/test/offloading/info.c`
