Hi Yuao,
first, good to have you on board!
As I am relatively new to submitting patches via mailing lists, I would
like to
send a very simple patch primarily to familiarize myself with the correct
procedure. I have reviewed the contribution guidelines on the GCC
website and
have tried to follow them closely.
The patch itself is OK.
There should be a ChangeLog entry. You can generate a template by
running your patch through contrib/mklog.py, which you can then fill
out with the details.
Best regards
Thomas
