C到黄金转换，为什么我的代码不能工作？

Question

这些天我遇到了一个问题，我需要把c代码转换成golang。我试过convert.It不起作用。

id应该是db_和table_64的子数据库和子表；id :3ca042611c8411e3b068 db_d0189890a。

C代码：

uint64_t __fastcall LiveHash(const char *key, int len, int left, int right)
{
  int v4; // ecx
  unsigned __int8 *v5; // r8
  int v6; // er9
  int v7; // eax
  int v8; // edx
  int v9; // ecx
  unsigned int v10; // eax
  int v11; // eax
  unsigned int v12; // eax
  int v14; // eax
  unsigned int v15; // eax

  if ( len <= 0 || !key )
    return 0LL;
  v4 = len;
  v5 = (unsigned __int8 *)key;
  if ( len >> 2 > 0 )
  {
    v6 = len >> 2;
    do
    {
      v7 = v5[3];
      v8 = v4 + *v5 + (v5[1] << 8);
      v9 = v5[2];
      v5 += 4;
      v10 = (v8 << 16) ^ v8 ^ ((v9 + (v7 << 8)) << 11);
      --v6;
      v4 = v10 + (v10 >> 11);
    }
    while ( v6 );
    v5 = (unsigned __int8 *)&key[4 * ((len >> 2) - 1) + 4];
  }
  v11 = len & 3;
  switch ( v11 )
  {
    case 2:
      v4 = ((v4 + *v5 + (v5[1] << 8)) ^ ((v4 + *v5 + (v5[1] << 8)) << 11))
         + (((v4 + *v5 + (v5[1] << 8)) ^ ((v4 + *v5 + ((unsigned int)v5[1] << 8)) << 11)) >> 17);
      break;
    case 3:
      v14 = v4 + *v5 + (v5[1] << 8);
      v15 = v14 ^ ((char)v5[2] << 18) ^ (v14 << 16);
      v4 = v15 + (v15 >> 11);
      break;
    case 1:
      v4 = ((v4 + (char)*v5) ^ ((v4 + (char)*v5) << 10))
         + (((v4 + (char)*v5) ^ (unsigned int)((v4 + (char)*v5) << 10)) >> 1);
      break;
  }
  v12 = ((v4 ^ (unsigned int)(8 * v4)) >> 5) + (v4 ^ 8 * v4);
  return (((v12 ^ 4 * v12) >> 15) + (v12 ^ 4 * v12)) ^ ((((v12 ^ 4 * v12) >> 15) + (v12 ^ 4 * v12)) << 10);
}

我的围棋代码：

func hash(guid string)int{
    v5 := make([]int, len(guid))
    for i := range guid{
        v5[i]= int(guid[i])
    }
    fmt.Println(v5)
    var v7,v8,v9, v10 int
    v4 := len(guid)
    if v4 >> 2 > 0{
        v6 := v4>>2
        for i:=v6;i>0;i--{
            v7 = v5[3]
            v8 = v4+v5[0]+(v5[1]<<8)
            v9 = v5[2]
            v10 = (v8<<16) ^ v8 ^((v9+(v7<<8))<<11)
            v6--
            v4 = v10+(v10>>11)
        }
        start := 4*((v4>>2)-1)+4
        if start < 0{
            start = 0
        }
        v5 = v5[start:]
    }
    v11:= v4&3
    switch v11 {
    case 2:
        v4 = ((v4+v5[0]+(v5[1]<<8))^((v4+v5[0]+(v5[1]<<8))<<11))+
            (((v4+v5[0]+(v5[1]<<8)) ^ ((v4+v5[0]+(v5[1]<<8))<<11))>> 17)
    case 3:
        v14:=v4+v5[0]+(v5[1]<<8)
        v15 := v14^(v5[2]<<18)^(v14<<16)
        v4 = v15+(v15>>11)
    case 1:
        v4 = ((v4+v5[0])^((v4+v5[0])<<10))+(((v4+v5[0])^((v4+v5[0]) << 10))>>1)
    }
    v12 := ((v4^(8*v4))>>5)+(v4^8*v4)
    return (((v12^4*v12)>>15)+(v12^4*v12))^((((v12^4*v12)>>15)+(v12^4*12))<< 10)
}

我的函数运行结果是2782879514833785705，不知道如何将子数据库和子表转到db_和table_64；

这是我的密码，哈哈

func hash(guid string)uint32{
    v5 := make([]uint8, len(guid))
    for i := range guid{
        v5[i]= guid[i]
    }
    var v7,v8,v9 int32
    var v10 uint32
    v4 := int32(len(guid))
    if v4 >> 2 > 0{
        v6 := v4>>2
        for i:=v6;i>0;i--{
            v7 = int32(v5[3])
            v8 = v4+int32(v5[0])+(int32(v5[1])<<8)
            v9 = int32(v5[2])
            v5 = v5[4:]
            v10 = uint32((v8<<16) ^ v8 ^((v9+(v7<<8))<<11))
            v6--
            v4 = int32(v10+(v10 >> 11))
        }
    }
    v12 :=  int32(int64(uint32(v4^int32(uint32(8*v4)))>>5)+int64(v4^8*v4))
    v13 := uint32(v12)
    v14 := int32((v13^4*v13)>>15)
    v15 := v12^4*v12
    return uint32((v14+v15)^((v14+v15)<< 10))
}

Answer 2

我有一些关于数学计算的代码，在python中正常工作。它能工作100000000次。但是在go中，它只能给我正确的答案100000,100000000次将停止在一个高CPU的使用，而从来没有给我答案。

66811根20 0 703688 6808 1200 S 100.7 0.3 3:52.52

我想，这是一个内存问题，但实际上，CPU问题。我不知道怎么修理。

同样的问题？golang math can not finished with my code, but python is ok
