You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: farmhashmk.go
    path of file: ./repos/goreportcard/vendor/github.com/dgryski/go-farm
    
    the code of the file until where you have to start completion: package farm

import (
	"encoding/binary"
	"math/bits"
)

func hash32Len5to12(s []byte, seed uint32) uint32 {
	sle
    
func hash32Len5to12(s []byte, seed uint32) uint32 {
	slen := len(s)
	a := uint32(len(s))
	b := uint32(len(s) * 5)
	c := uint32(9)
	d := b + seed
	a += binary.LittleEndian.Uint32(s[0 : 0+4])
	b += binary.LittleEndian.Uint32(s[slen-4 : slen-4+4])
	c += binary.LittleEndian.Uint32(s[((slen >> 1) & 4) : ((slen>>1)&4)+4])
	return fmix(seed ^ mur(c, mur(b, mur(a, d))))
}
