Dear GCC help pages maintainers,
I recently encountered a statement like this one
__attribute__((__mode__(__DI__)))
in a micro kernel source file.
As I'm not so skilled with this kind of C/C++ syntax I tried to read the
manual about the keywords involved in that expression. Despite I found
information about "__attribute__" and "__mode__" I wasn't able to find
information about "__DI__" (on the gcc manual pages). Of course I found
in Internet partial explanation of the meaning of "__DI__" keyword and
also found out that there are many of the same type like "__SI__",
"__HI__", and "__QI__". By the way, do they mean Double-, Single-,
Half-, Quarter-, -Integer?
The point is that it seem to me those identifiers are actually keywords
of the compiler. So they really have be mentioned (at least) in the
compiler manual. Better would be if they are explained. I guess that
part of the manual is not so well maintained because I found only
reference to the keywords "__byte__" or "__word__" or "__pointer__".
This message is just to inform u about something if u have the time to
work about has to be done (in my opinion) .
Best regards,
