函数名称：Update chains up to ip (excluded)

函数原型：static inline __attribute__((__always_inline__)) void LZ4HC_Insert(LZ4HC_CCtx_internal *hc4, const BYTE *ip)

返回类型：void

参数：

类型参数名称
LZ4HC_CCtx_internal *hc4
const BYTE *ip
77  chainTable等于chainTable
78  hashTable等于hashTable
79  base等于All index relative to this position
80  target等于ip减base
81  idx等于dex from which to continue dict update
83  当idx小于target循环
84  h等于LZ4HC_hashPtr(base + idx)
85  delta等于idx减hashTable[h]
87  如果delta大于MAX_DISTANCE则delta等于MAX_DISTANCE
90  aster (idx)等于delta
92  hashTable[h]等于idx
93  idx自加
96  dex from which to continue dict update 等于target
