+// Unaligned memory access is automatically enabled for "common" CPU, such as x86.\r
+// For others CPU, the compiler will be more cautious, and insert extra code to ensure aligned access is respected.\r
+// If you know your target CPU supports unaligned memory access, you want to force this option manually to improve performance.\r
+// You can also enable this parameter if you know your input data will always be aligned (boundaries of 4, for U32).\r

+# define XXH_USE_UNALIGNED_ACCESS 1\r
+#endif\r
+\r
+// XXH_ACCEPT_NULL_INPUT_POINTER :\r
+// If the input pointer is a null pointer, xxHash default behavior is to trigger a memory access error, since it is a bad pointer.\r
+// When this option is enabled, xxHash output for null input pointers will be the same as a null-length input.\r
+// This option has a very small performance cost (only measurable on small inputs).\r
+// By default, this option is disabled. To enable it, uncomment below define :\r
+//#define XXH_ACCEPT_NULL_INPUT_POINTER 1\r
+\r
+// XXH_FORCE_NATIVE_FORMAT :\r
+// By default, xxHash library provides endian-independant Hash values, based on little-endian convention.\r
+// Results are therefore identical for little-endian and big-endian CPU.\r
+// This comes at a performance cost for big-endian CPU, since some swapping is required to emulate little-endian format.\r
+// Should endian-independance be of no importance for your application, you may set the #define below to 1.\r
+// It will improve speed for Big-endian CPU.\r
+// This option has no impact on Little_Endian CPU.\r

-// When this option is enabled, xxHash output for null input pointers will be the same as a null-length input.\r
