Changlog: 1. 修改根目录下的scons编译配置文件“SConstruct” 增加mips架构处理器配置支持。 2. 增加mips架构暂停宏定义MONGO_YIELD_CORE_FOR_SMT（汇编）到头文件pause.h中。 3. third_party IntelRDFPMathLib20U1 增加mips架构编译配置。 4. third_party gperftools 通过脚本，platform增加mips架构支持源码。 5. third_party mozjs 通过脚本“./get-sources.sh ”从官源下载mozjs源码。 在脚本gen-config.sh中，增加生成mips架构源码的配置，利用脚本“./gen-config.sh mips64el linux”自动生成mips架构源码到platform文件夹中。 通过脚本./extract.sh生成mongodb所需源码并修改完善。 6. third_party wiredtiger 修改scons编译配置文件及脚本“SConstruct”和“SConscript”。 增加mips架构下的crc32算法代码支持。（当前不支持硬件加速计算） 增加mips架构源码路径配置到filelist中。

Hi @wenyunwei. I am cleaning up our pull request queue and saw this was from 5 years ago, and we have many changes since then. I am going to close this PR - if you make another one, can you please also create a new SERVER ticket on JIRA so we can track and prioritize this? Thanks! |

Add mips arch support. Test on loongson cloud platform(base on loongson 3A4000)
I noted that there was a pull request before, but it was rejected. The main reason is mongodb version too old, and you don't have test machine for mips arch.
We have modified and tested it in the master brach.
If necessary, We can provide a mips arch test environment by an account of loongson cloud platform.
In the third party, most of the changes are related to the configuratin of the arch. Only "mozjs-60" and "wiredtiger" require some simple source code changes.
