I worked on an unreleased third-party C compiler for the i860. It wasn't that compilers couldn't handle the double-issue float mode, it was more that it was worthless in real-world code due to the entry/exit latency. It had high performance on paper but not in reality, which was exactly the lesson that Intel did not learn for the Itanium.
