Is there an updated "OpenMP Representation in LLVM IR" document?

Runtimes OpenMP

Hello,

Is there a more recent version of the "OpenMP Representation in LLVM
IR" document that was originally posted here:
http://lists.cs.uiuc.edu/pipermail/llvmdev/2012-September/053870.html

I asked on the llvmdev list (where the original mail was posted), but
received no response.

Thanks!

Hi Matt,

Sorry for the lack of reply. We're not currently using a representation like that at all. Clang is directly lowering OpenMP constructions into calls to our OpenMP runtime library. There is no particular IR representation.

Thanks for the information Hal. I will wipe all knowledge of the
previous document from my brain.

Matt,

The most up-to-date information on how OpenMP is supported in clang
compiler can be found in Alexey Bataev's and Zinovy Nis' talk at last
year's LLVM conference.

As for the proposal you referred to, it wasn't accepted in the
community. There were a few proposals to extend LLVM IR to provide
more expressive support for OpenMP, but none of them got enough
traction.

Yours,
Andrey
