Tried building the experimental PR here, as well as switching to static linking against LLVM 20, however:

In file included from /home/runner/.julia/artifacts/0c8a7d47e3327c7247a3a4c60fb6df027918c6f9/include/LLVMSPIRVLib/LLVMSPIRVLib.h:44,
                 from /home/runner/work/OpenCL.jl/OpenCL.jl/pocl/lib/CL/pocl_llvm_spirv.cc:67:

   42 | #include <llvm/ADT/Optional.h>
      |          ^~~~~~~~~~~~~~~~~~~~~
compilation terminated.

... so I guess mixing LLVM 20 with LLVM-SPIRV translator 16 does not work, and we'll have to link that one statically as well.

[maleadt]

Yay, just a single segfault. Probably because of having switched to LLVM 20, which is still kinda experimental with PoCL.

[maleadt]

Huh, the same segfault. Guess I'll have to reduce that.

[maleadt]

Awesome, this passes tests :-)
