Log:
libc: tag the Rune initialization function prototypes visibility as hidden.
How does this interact with symbol versioning/mapping? Wouldn't our C
library's symbol map already make these symbols hidden without any
explicit annotation?
It shouldn't hurt at all, this is not the first use that we make of the
visibility attributes in libc. I do notice we tend to put them at the
end of the prototype, while I followed the Apple notation of setting
them in front. No idea if that is worthwhile to change.
It is true that these symbols should already be hidden but in the case
some port is using -fvisibility= compiler flag this will prevent the
symbols from getting exported by accident.
Pedro.
