================
Comment at: clang/lib/CodeGen/BackendUtil.cpp:1470
+  case Triple::XCOFF:
+    // TODO: Falling through for XCOFF format for now.
+    break;
----------------
This is confusing, you say fall through but you break? I would prefer a `llvm_unreachable("XCOFF not yet implemented");` here and elsewhere in this patch. 



================
Comment at: clang/lib/CodeGen/BackendUtil.cpp:1486
+  case Triple::XCOFF:
+    // TODO: Falling through for XCOFF format for now.
+    break;
----------------
See previous comment.


================
Comment at: clang/lib/CodeGen/CodeGenModule.cpp:4410
+  case llvm::Triple::XCOFF:
+    llvm_unreachable("to be determined for XCOFF format");
   case llvm::Triple::COFF:
----------------
See previous comment.


================
Comment at: lldb/source/Plugins/Process/gdb-remote/GDBRemoteCommunicationClient.cpp:2079
+          if (log)
+            log->Printf("sorry: unimplemented for XCOFF");
+          return false;
----------------

Just bundle this with the WASM case, the error message is correct for both.


================
Comment at: llvm/lib/MC/MCContext.cpp:165
+    case MCObjectFileInfo::IsXCOFF:
+      // TODO: Need to implement class MCSymbolXCOFF.
+      break;
----------------
See previous comment.
