#define XXHASH_H_5627135585666179 1

XXH_INLINE_ALL (and XXH_PRIVATE_API) Use these build macros to inline xxhash into the target unit. Inlining improves performance on small inputs, especially when the length is expressed as a compile-time constant:

 https://fastcompression.blogspot.com/2018/03/xxhash-for-small-keys-impressive-power.html

It also keeps xxHash symbols private to the unit, so they are not exported.

Usage: #define XXH_INLINE_ALL #include "xxhash.h"

Do not compile and link xxhash.o as a separate object, as it is not useful.
