+.Sh DESCRIPTION
+Function
+.Fn dwarf_add_expr_addr_b
+adds a
+.Dv DW_OP_addr
+location expression to the location expression descriptor referenced
+by argument
+.Ar expr .
+.Pp
+Argument
+.Ar expr
+should reference a location expression descriptor allocated using
+the function
+.Xr dwarf_new_expr 3 .
+.Pp
+Argument
+.Ar address
+specifies the operand, a relocatable address value.
+.Pp
+Argument
+.Ar sym_index
+specifies the ELF symbol index of the symbol to be used for
+relocation.
+.Pp
+If argument
+.Ar err
+is not NULL, it will be used to store error information in case
+of an error.
+.Pp
+Function
+.Fn dwarf_add_expr_addr
+is deprecated.
+It is similar to function
+.Fn dwarf_add_expr_addr_b
+except that it cannot handle all possible symbol index values.
+.Sh RETURN VALUES
+On success, these functions return the size in bytes of the location
+expression byte stream generated.
+In case of an error, these functions return
+.Dv DW_DLV_NOCOUNT
+and set the argument
+.Ar err .
+.Sh ERRORS
+These functions can fail with:
+.Bl -tag -width ".Bq Er DW_DLE_ARGUMENT"
+.It Bq Er DW_DLE_ARGUMENT
+Argument
+.Ar expr
+was NULL.
+.It Bq Er DW_DLE_MEMORY
+An out of memory condition was encountered during the execution of
+the function.
