            Bug ID: 45742
           Summary: MC: Support for wasm globals other than
                    __stack_pointer is missing
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Backend: WebAssembly
          Assignee: unassignedbugs at nondot.org
          Reporter: sbc at chromium.org
                CC: llvm-bugs at lists.llvm.org

It would be useful to be able to support wasm global in the asm format and
object file format.

Currently we only support certain wasm globals such as __stack_pointer.

Trying to define other new globals in the assembly format currently results in:

```
clang -cc1as: fatal error: error in backend: don't yet support defined globals
```
