[Jordan Rupprecht via Phabricator via llvm-commits]

rupprecht added inline comments.


================
Comment at: llvm/lib/Target/AArch64/AArch64FrameLowering.cpp:443-445
+  // Build up the expression (SP + NumBytes + NumVGScaledBytes * AArch64::VG)
+  SmallString<64> Expr;
+  Expr.push_back(dwarf::DW_OP_breg0 + /*SP*/ 31);
----------------
I'm seeing the following warning here:

```

  Expr.push_back(dwarf::DW_OP_breg0 + /*SP*/ 31);

```

Do you see it as well? Is there a way to silence it?
