They didn't really pan out in terms of large uptake. They did solve some problems pretty well with shorter, developer time. There's also been open source ones designed. Here's a few:
Many of the other ones seem dead or don't have a software page. I'm not sure what's current in FOSS HLS with C-like languages. Anyone know of other developments at least as good as the two I linked?
Nitpick: LegUp is published under a "no commercial use" license. Synflow mentions they use a "open-source language" but it is not clear how much of the tool chain is open source.
