URL: https://github.com/llvm/llvm-project/commit/7f415e444197025180d786c5e212f13b738179cb DIFF: https://github.com/llvm/llvm-project/commit/7f415e444197025180d786c5e212f13b738179cb.diff LOG: [clang][SYCL] Disable float128 device mode diagnostic (#128513) This diagnostic is disabled for device compilation as float128 is not supported on the device side. Other diagnostics are already covering the cases where float128 is actually used in the kernel code, and it's already tested for in the existing test. This is expanding on the patch 318bff6 that handled this for cuda compilation.
