Subject: Re: [PATCH] diagnostics.h: GCC 13 got -Wself-move, breaks GDB build
Date: Mon, 3 Oct 2022 14:49:55 +0100	[thread overview]
Message-ID: <670fd724-f14f-565f-b4a1-5883a8a1b5ab@redhat.com> (raw)

Hi Jan-Benedict,

> +# if __GNUC__ >= 13
> +#  define DIAGNOSTIC_IGNORE_SELF_MOVE DIAGNOSTIC_IGNORE ("-Wself-move")
> +# endif

There appears to be a convention that the definition should be broken
up over two lines, ie:

   # if __GNUC__ >= 13
   #  define DIAGNOSTIC_IGNORE_SELF_MOVE \
      DIAGNOSTIC_IGNORE ("-Wself-move")
   # endif

Although DIAGNOSTIC_ERROR_SWITCH appears to be the exception to this rule.

More importantly however, you need to provide an empty definition at the
end of the file should the macro not be defined.  ie:

   #ifndef DIAGNOSTIC_IGNORE_SELF_MOVE
   # define DIAGNOSTIC_IGNORE_SELF_MOVE
   #endif

Cheers
   Nick
