--- Comment #24 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-07-22 17:16:43 UTC --- As far as I can see, Vincenzo, in that case the problem is a bit different, because those functions aren't ISO: should Intel issue an updated document describing the builtins and acknowledging the new C++? To be honest I know little about the way those builtins are "standardized", the way Intel issues updates to the specs. Maybe you could open about that a separate "exploratory" Bugzilla (in CC people like Uros)?!?
