"avoid using named labels" mis-identifies inst operand as label

[androm3da]

Code

// In hexagon assembly syntax, register pairs are delimited with colons like `r17:16`.


pub unsafe fn hexagon_regpair_example() {
    asm!(
        // this instruction performs a double-word load to r1 and r0
        "r1:0 = memd(r29+#0)",
        lateout("r0") _, lateout("r1") _
    );
}

Current output

error: avoid using named labels in inline assembly
  --> src/lib.rs:23:10
   |
23 |         "r1:0 = memd(r29+#0)",
   |          ^^
   |

Desired output

<not an error - no diagnostic emitted>

Rationale and extra context

If you have a pointer to other similar "narrowing the pattern matched for this diag" commit(s) I can make the change.
