Hi again, Regarding building https://github.com/etcd-io/etcd.git with gollvm -- I have a fix for the compiler problem you ran into, but in my testing I've run into other problems that are not amenable to compiler fixes. Specifically, it looks as though some of the dependent packages for etcd are not compatible with gccgo/gollvm:
/tmp/go/pkg/mod/github.com/modern-go/reflect2@v1.0.1/type_map.go:42: error: undefined reference to 'reflect.typelinks' /tmp/go/pkg/mod/github.com/modern-go/reflect2@v1.0.1/type_map.go:74: error: undefined reference to 'reflect.typelinks' /tmp/go/pkg/mod/github.com/modern-go/reflect2@v1.0.1/type_map.go:78: error: undefined reference to 'reflect.resolveTypeOff' /tmp/go/pkg/mod/ golang.org/x/sys@v0.0.0-20180909124046-d0be0721c37e/unix/gccgo.go:50: error: undefined reference to 'gccgoRealSyscallNoError' /tmp/go/pkg/mod/ golang.org/x/sys@v0.0.0-20180909124046-d0be0721c37e/unix/gccgo.go:23: error: undefined reference to 'gccgoRealSyscallNoError' /tmp/go/pkg/mod/ golang.org/x/sys@v0.0.0-20180909124046-d0be0721c37e/unix/gccgo.go:30: error: undefined reference to 'gccgoRealSyscall' /tmp/go/pkg/mod/ golang.org/x/sys@v0.0.0-20180909124046-d0be0721c37e/unix/gccgo.go:37: error: undefined reference to 'gccgoRealSyscall' /tmp/go/pkg/mod/ golang.org/x/sys@v0.0.0-20180909124046-d0be0721c37e/unix/gccgo.go:44: error: undefined reference to 'gccgoRealSyscall' /tmp/go/pkg/mod/ golang.org/x/sys@v0.0.0-20180909124046-d0be0721c37e/unix/gccgo.go:55: error: undefined reference to 'gccgoRealSyscall' error: ld returned 1 exit status The vendored copy of golang.org/x.sys seems to be targeting gccgo symbols that no longer exist (e.g. "gccgoRealSyscall"), and the "modern-go/reflect2" package is using unsafe to reach into the reflect package to access symbols that are only present in the main Gc version of the runtime... without work done to fix these issues the application is not going to be buildable with gollvm.
