2K1000龙芯派上编译Go
我是在一代派上编译的Go,yum install golang也可以安装龙芯官方的go1.9，但是不能build。我就删除了官方源的go,按照龙芯开源社区官方的龙芯Go！Go！Go！——龙芯平台上构建Go语言环境指南的做法自举编译Go http://www.loongnix.org/index.php/%E6%96%87%E7%AB%A0/loongson-go我的x86本本上是deepin 15.10
在x86机子上下载go1.4.2.linux-amd64.tar.gz go1.12.5.src.tar.gz
sudo tar zxvf go1.12.5.src.tar.gz -C /opt/golang/
susudo passwd rootsu
export GOROOT_BOOTSTRAP=/opt/go1.4.2
设置GOROOT_BOOTSTRAP 以后编译总是报错，说要root路径下的1.4.
我这边干脆把opt下的1.4.2mv到root路径下
mv /opt/go1.4.2 /root/
cd /opt/golang/go/src
GOOS=linux GOARCH=mips64le ./bootstrap.bash
如果遇到失败的情况则rm -rf ../../go-linux-mips64le-bootstrap（执行./bootstrap.bash会在上二级路径下生成我们要的go-linux-mips64le-bootstrap）
然后按照http://www.loongnix.org/index.php/%E6%96%87%E7%AB%A0/loongson-go的第二阶段：在龙芯平台上从源代码构建Go 1.6开发环境。的做法继续。
把go-linux-mips64le-bootstrap.tbz拷贝到派上，解压，然后mv到/root下，直接解压到/root/go1.4下
在派上我用的源码是 go1.12.4.src.tar.gz的
env.sh的shell脚本里面GO_TEST_TIMEOUT_SCALE的值我设为3,派用的高速U盘还是比龙芯台式机的磁盘io速度慢。
#!/bin/bash
export GOROOT_BOOTSTRAP=/root/go1.4
export GOROOT=/root/workspace/go
export GO_TEST_TIMEOUT_SCALE=3
先上图和编译记录
派开机后先清理内存，编译Go，很耗内存，清理内存以后一直到开始Testing packages不要再动内存了，但是不放心的话可以另开一个终端页面查看内存，测试完一项后会自动回收内存的，但是进行到 测试cmd/compile/internal/ssa的时候，我这边内存刚好耗光了，然后死机，其实这个时候可以耐心等待系统慢慢回复的，大概等了3分钟，go build cmd/compile/internal/ssa: /root/workspace/go/pkg/tool/linux_mips64le/compile: signal: killed
这个测试项kill掉了，开始测试下一个，内存也恢复到了1000多M.最后测试有一部分失败了，但是没关系，只要go编译好了就行。
go1.12.4 linux/mips64le
输出helloworld我这里打成shijie了:)

cmd/internal/obj是机器码生成的模块，这里x86和arm64机器码生成测试也能通过，福莱讲这个是检测编译器内部正确性，不执行，所以能通过，群里爱好编译器的也可以研究一下go是怎么写汇编程序的，在cmd/internal/obj里面，有x86,arm64,mips
