Using group_barrier from virtual functions leads to UR_RESULT_ERROR_PROGRAM_LINK_FAILURE #15068
Description
Describe the bug
sycl/test-e2e/VirtualFunctions/misc/group-barrier.cpp that is added by #15067 fails on GPU when we link device images at runtime with UR_RESULT_ERROR_PROGRAM_LINK_FAILURE.
To reproduce
That's an in-tree e2e test, it should be clear how to reproduce it.
Environment
- OS: Linux
- Target device and vendor: I've only checked PVC, but that's unlikely device-specific
- DPC++ version: most recent intel/llvm build
- Dependencies version: I have NEO 24.22.29735.20 installed on my machine
Additional context
If I capture SPIR-V files that we send to IGC, reverse translate them into LLVM IR and link manually using llvm-link that operation succeeds, which makes me think that this is actually an IGC issue.
