+// The local_accessor_kernel spv files were generated from the SYCL program
+// included in this comment. The program can be compiled using
+// `icpx -fsycl local_accessor_kernel.cpp`. After that if the generated
+// executable is run with the environment variable `SYCL_DUMP_IMAGES=1`, icpx
+// runtime will dump all offload sections of fat binary to the current working
+// directory. When tested with DPC++ 2024.0 the kernels are split across two
+// separate SPV files. One contains all kernels for integers and FP32
+// data type, and another contains the kernel for FP64.
+//
+// Note that, `SYCL_DUMP_IMAGES=1` will also generate extra SPV files that
+// contain the code for built in functions such as indexing and barriers. To
+// figure which SPV file contains the kernels, use `spirv-dis` from the
+// spirv-tools package to translate the SPV binary format to a human-readable
+// textual format.
