[cfe-dev] Cilk Plus extensions in LLVM/Clang

[Hal Finkel]

Ben,

This is great news! Thanks for making sure this ended up in the open.

Now what I'd like is some kind of (perhaps informal) "porting guide" for the compiler and the runtime. I'll want to get this working on other architectures, operating systems, etc.

 -Hal

> This code currently supports the _Cilk_spawn and _Cilk_sync tasking
> keywords, as well as hyperobjects and the runtime library. The

> The implementation of _Cilk_spawn uses our original implementation of
> captured statements. We recently proposed this feature to cfe-dev
> for inclusion in trunk, and an improved version of captured
> statements is currently in review. We hope to continue upstreaming
> improvements that are valuable to the broader Clang community into
> trunk as they come up.
