            Bug ID: 42441
           Summary: MC: Location info for fixups in .s files 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

Fixup issues are always reported as "<unknown>:0: error: ..."

e.g.

$ llvm-mc -triple=wasm32-unknown-unknown test.s -filetype=obj -o tmp.o
<unknown>:0: error: Cannot represent a difference across sections

Where as x86 gives:

$ llvm-mc -triple=i686-linux-gnu  test.s -filetype=obj -o tmp.o
test.s:16:9: error: Cannot represent a difference across sections


Wasm .s file:

```
  .section    .rodata.foo,"",@
  .hidden     foo
foo:
  .int8       1
  .int8       4
  .int8       2
  .size       foo, 3

  .section    .rodata.bar,"",@
  .hidden     bar
bar:
  .int8       9
  .int8       8
  .size       bar, 2

  .text
  .section .text.test_annotation,"",@
main:
  .functype   main () -> (i32)
  i32.const foo-bar
  end_function

```
