/// Tests for SYCL offloading JIT that require Unix commands (rm, ln, mkdir, touch)
// These tests require a fake install tree with a symlinked clang so that D.Dir points to a
// controlled location, allowing us to place a dummy libLLVMSYCL.so where the driver expects it.
// UNSUPPORTED: system-windows, system-cygwin

// Check if path to the SYCL RT is passed to clang-linker-wrapper for SYCL compilation.
// The test also checks if SYCL header include paths are added to the SYCL host and device compilation.

// Check LLVM_ENABLE_PER_TARGET_RUNTIME_DIR=ON case: library is in lib/<triple>/
