This is OK, but:

+/* AARCH64 extensions.
+   DW_OP_AARCH64_operation takes one mandatory unsigned LEB128 operand.
+   Bits[6:0] of this operand is the action code, all others bits are
initialized
+   to 0 except explicitly documented for one action.  Please refer
AArch64 DWARF
+   ABI documentation for details.  */

Is it possible to include a stable URL that points to the ABI document?
