Problems in Dpc++ build

tneval — Wed, 05 Feb 2025 15:44:26 GMT

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 ******************** ******************** Failed Tests (41): LLVM_SPIRV :: AtomicBuiltinsFloat.ll LLVM_SPIRV :: AtomicCompareExchange.ll LLVM_SPIRV :: AtomicCompareExchange_cl20.ll LLVM_SPIRV :: CXX/global-ctor.cl LLVM_SPIRV :: EnqueueEmptyKernel.ll LLVM_SPIRV :: SpecConstants/spec-constant-length-array.ll LLVM_SPIRV :: array-alloca.ll LLVM_SPIRV :: atomic-load-store.ll LLVM_SPIRV :: atomicrmw.ll LLVM_SPIRV :: entry-point-interfaces.ll LLVM_SPIRV :: extensions/EXT/SPV_EXT_relaxed_printf_string_address_space/builtin_printf.ll LLVM_SPIRV :: extensions/INTEL/SPV_INTEL_cache_controls/decorate-prefetch-w-cache-controls.ll LLVM_SPIRV :: extensions/KHR/SPV_KHR_cooperative_matrix/access_store.ll LLVM_SPIRV :: extensions/KHR/SPV_KHR_cooperative_matrix/access_store_untyped.ll LLVM_SPIRV :: extensions/KHR/SPV_KHR_untyped_pointers/infinite-phi.ll LLVM_SPIRV :: extensions/KHR/SPV_KHR_untyped_pointers/store.ll LLVM_SPIRV :: extensions/KHR/SPV_KHR_untyped_pointers/untyped_ptr_access_chain.ll LLVM_SPIRV :: extensions/KHR/SPV_KHR_untyped_pointers/untyped_ptr_type.ll LLVM_SPIRV :: extensions/KHR/SPV_KHR_untyped_pointers/untyped_var.spvasm LLVM_SPIRV :: group_non_uniform_shuffle_down.ll LLVM_SPIRV :: link-attribute.ll LLVM_SPIRV :: llvm-intrinsics/lifetime.ll LLVM_SPIRV :: llvm-intrinsics/memmove.ll LLVM_SPIRV :: llvm-intrinsics/memset-opaque.ll LLVM_SPIRV :: spirv_global_variable_decoration.ll LLVM_SPIRV :: transcoding/AtomicCompareExchangeExplicit_cl20.cl LLVM_SPIRV :: transcoding/AtomicCompareExchange_cl20.ll LLVM_SPIRV :: transcoding/BuiltinPrintf.cl LLVM_SPIRV :: transcoding/OpenCL/atomic_cmpxchg.cl LLVM_SPIRV :: transcoding/OpenCL/atomic_legacy.cl LLVM_SPIRV :: transcoding/OpenCL/atomic_syncscope_test.ll LLVM_SPIRV :: transcoding/Printf.cl LLVM_SPIRV :: transcoding/atomic_load_store.ll LLVM_SPIRV :: transcoding/builtin_calls.ll LLVM_SPIRV :: transcoding/builtin_vars.ll LLVM_SPIRV :: transcoding/enqueue_marker.cl LLVM_SPIRV :: transcoding/get_image_num_mip_levels.ll LLVM_SPIRV :: transcoding/multiple_user_semantic.ll LLVM_SPIRV :: transcoding/ptr_diff.ll LLVM_SPIRV :: transcoding/ptr_not_equal.ll LLVM_SPIRV :: transcoding/undef-gv.ll

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.
