Hi Guys,
Redefining a previously defined static function as both public and
weak triggers an ICE in ipa-visibility.c:
internal compiler error: in function_and_variable_visibility, at
ipa-visibility.c:518
This bug has been discussed and patch proposed here:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=49899
This submission is an updated version of that patch, made against
the latest gcc sources. It still chooses to generate an error message
and disallow the conversion, which I hope is the correct action.
OK to apply ?
Cheers
Nick

Does this fix a regression? Essentially I'm trying to figure out if we
want this for gcc-6 or gcc-7.
