There are at least two concurrent efforts that work on an IR extension
similar to what you cite below, one by Intel and one by a researcher
working group. Afaik, both will approach the community in the next few
weeks. (And to make sure they'll see your mail I put them all in the
In the meantime you could take a look at this proposal . It is not
an IR extension but an abstraction layer that allows to design and
test parallel specific analysis and optimizations on both current and
future parallel representations.
I realized you saw the proposal already but I didn't want to remove
the paragraph about it once I was done.
