enum lldb_private::wasm::WasmAddressType : uint8_t

Each WebAssembly module has separate address spaces for Code and Memory.

A WebAssembly module also has a Data section which, when the module is loaded, gets mapped into a region in the module Memory.

Globals are not addressable: they live in an index space of their own. The synthetic Global space stands in for one, holding the index where an address would hold an offset, so that a global can be named and read.

The tag is two bits wide and these are the only spaces there are, so the remaining value means an address that belongs to nothing.
