There's an Airport Planning Doc at airbus.com (see under the 380 family on the main site rather than the reveal site) which gives graphs for temps/alts/weights and runway lengths required for Trent and GP engines, freight and pax versions.
As has been pointed out, many aircraft can beat the "standard" runway restriction if the performance penalty is worth it (say a ferry after an emergency landing at a short field, using min fuel and no pax/cargo)
