Re: [go-nuts] Build kubernetes with gollvm

Hello Yuan Ting: I am trying to build Kubernetes with gollvm, and I am glad you have made some progress. Did you finish compiling Kubernetes with gollvm and generating IR? If it is true, could you show me some practical steps so I can compile the Kubernetes to LLVM IR files? Looking forward to y

Brendan, could you review this and express your vision against the usage of https://godoc.org/k8s.io/kubernetes/third_party/forked/golang/reflect https://golang.org/pkg/reflect/ https://github.com/modern-go/reflect2 packages?

Hi Ivan, Yes, I still try to build famous projects by gollvm but there are still some troubles (such as https://groups.google.com/d/msg/golang-nuts/2fIk7hbbYJc/zIh3B4tbAAAJ ) The trouble mentioned here is gccgo compatibility of reflect2 (a package imported by k8s). The developers of reflect2 giv

Yuan, are you still working on gollvm based port of k8s? Ivan On Saturday, July 20, 2019 at 5:32:03 AM UTC+3 Yuan Ting wrote: > OK, I will check out the reflect2 package and take a look. Thanks a lot > for your direction! > > Best, > Ting > > On Friday, July 19, 2019 at 10:30:32 PM UTC+8, Ian L

Re: [go-nuts] Build kubernetes with gollvm

Sorry to have troubled you again, I found that many famous Go projects also import github.com/modern-go/reflect2 , such as kubernetes and moby. According to the second paragraph in your explanation, these popular projects will also failed in compilation. I think this may be a big challenge for

Re: [go-nuts] Build kubernetes with gollvm

Thank you. The explanation really makes sense. I think I should modify the source code of etcd, or change to another project that is not so hackful. On Thursday, July 18, 2019 at 10:55:39 PM UTC+8, Ian Lance Taylor wrote: > > On Thu, Jul 18, 2019 at 6:50 AM Yuan Ting > > wrote: > > > > Thank

Re: [go-nuts] Build kubernetes with gollvm

Hi Than Thank you for your fix. I have some curious about the difference between the main Go compiler and gollvm. I read gollvm's readme and know that the main difference comes from the efficiency of GC. Is the other difference causes the symbol undefined reference as you mentioned above? Or so

Re: [go-nuts] Build kubernetes with gollvm

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

Re: [go-nuts] Build kubernetes with gollvm

OK, thanks for checking on that. Sounds like this is a new problem (not too surprising, since this is an area of the compiler that is undergoing a lot of changes in recent weeks; tip is a bit unstable). I have my hands full with a couple of other bugs that I am juggling right now; filed issue htt

[go-nuts] Build kubernetes with gollvm

Hi, I'm working on converting some Go projects to llvm IR for static analysis. When I build kubernetes with gollvm, an unexpected error occurred as : I0709 10:48:29.158892 16573 deepcopy.go:266] Type k8s.io/apimachinery/pkg/apis/meta/v1.map_StatusDetails is not copyable I0709 10:48:29.158899
