I'll likely fork `userstack.ll` since the majority of lines need changes.



================
Comment at: lld/wasm/Driver.cpp:385
+    StringRef s = arg->getValue();
+    if (s == "wasm32")
+      config->is64 = false;

Yup, @sbc100 suggested this.


================
Comment at: llvm/lib/Target/WebAssembly/WebAssemblyMCInstLower.cpp:84
     WasmSym->setGlobalType(wasm::WasmGlobalType{
-        uint8_t(Subtarget.hasAddr64() ? wasm::WASM_TYPE_I64
-                                      : wasm::WASM_TYPE_I32),
+        uint8_t(Subtarget.hasAddr64() && strcmp(Name, "__table_base") != 0
+                    ? wasm::WASM_TYPE_I64

I'd think so, right? since it refers to table indices, not memory
