| 25 | * Note: MEM_MODULE stops xxhash redefining BYTE, U16, etc., which are also |
| 26 | * defined in mem.h (breaking C99 compatibility). |
| 27 | * |
| 28 | * Note: the undefs for xxHash allow Zstd's implementation to coincide with |
| 29 | * standalone xxHash usage (with global defines). |
| 30 | * |
| 31 | * Note: if you enable ZSTD_LEGACY_SUPPORT the combine.py script will need |
| 32 | * re-running without the "-x legacy/zstd_legacy.h" option (it excludes the |
| 33 | * legacy support at the source level). |
