[9fans] any updates on go for plan9/arm?

I just tried cross compiling go1.6beta1 for plan9/arm, using os x, but no luck. is it still planned for go1.6?

Re: [9fans] any updates on go for plan9/arm?

I've just updated the patch so it should apply cleanly on Go 1.6. Richard, I think the following files have to be updated to match Go 1.6: - src/cmd/go/build.go (rebase to the current file) - src/runtime/os3_plan9.go (regSize → sys.RegSize, ptrSize → sys.PtrSize and go:nowritebarrier →

Richard Miller's work on the plan9/arm port is available here: http://9legacy.org/go/patch/go-arm.diff It has been tested successfully on Rasperry Pi 2 (ARMv7) with *ncpu=1. There is still a coherency issue that need to be fixed to be able to run reliably on multiple processors. -- David du

> http://9legacy.org/go/patch/go-arm.diff Thank you, David for the details. There are many rPi owners out there and some may be willing to contribute their efforts, it matters that they are well informed. Is the coherency problem documented anywhere? I appreciate I ought to know the answer,

> A plan9/arm builder has been already running for two months. I knew I'd have to qualify my statement :-) In your opinion, will Go for plan9/arm be ready for inclusion in 1.7? Is there any work that needs additional resources to make that possible? Lucio.

Re: [9fans] any updates on go for plan9/arm?

I just went through the patch, aside from minor cosmetic changes, I think it's ready for inclusion into Go 1.7 if all.bash passes. The author just has to split it up into CLs and push to Gerrit for review.
