The VS2026 STL headers use
__isa_available(a runtime global variable) to detect CPU features. SYCL device code can't access host runtime globals, and that leads to failures. ( "SYCL kernel cannot use a non-const global variable." ) But we can define it easily and then things move forward.But once we are moving forward again, we encounter a second issue, the feature map is empty. The solution here is to just init the feature map like we already do in
SPIRV64AMDGCNTargetInfo::initFeatureMap.
