Problems in Dpc++ build

[tneval]

I cloned open source Dpc++ from https://github.com/intel/llvm.

(From commit 29044ff10b0a1a0ce6c5a8369d847ed20621cfca)

and I'm following these instructions:
https://intel.github.io/llvm/GetStartedGuide.html

python llvm/buildbot/configure.py -o ../build
python llvm/buildbot/compile.py -o ../build

It compiles fine, but llvm-spirv related tests seem to fail:

python llvm/buildbot/check.py -o ../build

It works on some level: I can compile and run some simple SYCL programs with it but
when trying to compile Gromacs with it, I get:

llvm-foreach: 
RequiresExtension: Feature requires the following SPIR-V extension:
 SPV_INTEL_fp_max_error

llvm-foreach: 
RequiresExtension: Feature requires the following SPIR-V extension:
 SPV_INTEL_fp_max_error

llvm-foreach: 
clang++: error: llvm-spirv command failed with exit code 18 (use -v to see invocation)

I also tried downloading pre-built release from Github page, but Gromacs installation gave same error.

Any idea where this could stem from?

Managed to overcome the issue by using non - open source version instead.
