}通过 objdump 生成 so 库的反汇编
命令行如下：
>J:\Programs\Android\sdk\ndk-bundle\toolchains\aarch64-linux-android-4.9\prebuilt\windows-x86_64\bin\aarch64-linux-android-objdump.exe -d libnative-lib.so > objdump_d.txt
一. arm-linux-objdump
常用来显示二进制文件信息,常用来查看反汇编代码
二. 常用选项:
1.-b bfdname 指定目标码格式
2.—disassemble或者-d 反汇编可执行段
3.—dissassemble-all或者-D 反汇编所有段
4.-EB,-EL指定字节序
5.—file-headers或者-f 显示文件的整体头部摘要信息
6.—section-headers,--headers或者-h 显示目标文件中各个段的头部摘要信息
7.—info 或者-I 显示支持的目标文件格式和CPU架构
8.—section=name或者-j name显示指定section 的信息
9.—architecture=machine或者-m machine 指定反汇编目标文件时使用的架构
三. 示例
Arm-linux-objdump –D elf_file > dis_file 或者
Arm-linux-objdump –D –b binary –m arm bin_file > dis_file

Neon 版在我的手机上是 “负优化” 。。。跑得比朴素 CPU 还慢。。。看来网上给的 NEON 代码也未必靠谱，还是得亲自实践对比！
经过我的优化后，NEON 版达到了 53ms 左右，展开（一次）版是51 ms左右，原图大小为 1600*1873
