I submitted a proposal for a Masterclass talk on ISPC at the Graphics Programming Conference in Breda, NL this fall. Fingers crossed it gets accepted! They are still accepting proposals/abstracts for talks if you're interested.

This should help make getting setup to contribute, or to build ISPC with specific versions of LLVM much easier!

Everyone told me when I started this that Windows Docker containers on Windows were a pain in the ass. They were right. But I still did it. I'm happy to release the first version of a Dockerfile for setting up a build environment for ISPC and LLVM

[ISPC @ispc_updates]

@touisteur As far as I know, right now it's about on par with the TGL CPU, but hopefully Arina can shed some more light on this for you.

[ISPC @ispc_updates]

@touisteur @ArinaNeshlyaeva, have you done any performance measurements on TGL iGPU vs TGL CPU?

[ISPC @ispc_updates]

@AgileJebrim @ArinaNeshlyaeva - do we have any data we can share?

[ISPC @ispc_updates]

We added a link mode to ISPC, enabling linking several LLVM bitcode or SPIR-V files while outputting LLVM bitcode or SPIR-V as a result.

ispc link test_a.bc test_b.bc --emit-spirv -o test.spv

The CMake utilities were also updated to support the ispc link feature.

New device names acm-g10, acm-g11, and acm-g12 were added for Intel® Arc™ Graphics. The dg2 device name has been removed.

Performance on Xe targets has been improved significantly by analyzing and automatically reducing register spilling.
