Dear,

Dcompute: https://github.com/libmir/dcompute need a SPIRV capable LLVM.
For this Dcompute project show https://github.com/thewilsonator/llvm as a SPIRV capable LLVM.

But it is not an official llvm source, moreover the source is outdated. Indeed it provide LLVM 5.0.0 while the current stable is the 6.0.0

Furthermore kronos group provide too an old SPIRV capable LLVM https://github.com/KhronosGroup/SPIRV-LLVM (3.6.1)

So can I use official LLVM source in order to use dcompute ?
If no, why the SPIRV feature part added to LLVM was not send to the upstream ?

Thanks

Best regard

It should provide 6.0.0, I'll fix this at DConf.

Yep it's wayyy too old.

No. I plan to fix this after DConf.

Because Khronos hasn't got their act together or doesn't understand the importance of widespread support.

Thanks Nicholas for this quick answer,

About to push your work on llvm SPIR V enabled , by official upstream (I was not very clear) I mean llvm.org not the khronos group. Indeed I see on the llvm.org page a project named  libclc : http://libclc.llvm.org/ and this project aims to implement the OpenCL standard library.

Maybe your work could be put to this official project ?

Have a nice day
