Re: [go-nuts] Why golang garbage-collector not implement Generational and Compact gc?

To perform concurrent compaction/copying you should use Read Barriers. Read barrier is very expensive. It is less expensive in Java, cause pointers always looks into beginning of allocation (so redirect pointer is in known position). But it will be very expensive in Go cause of interior

Re: [go-nuts] Freebsd - Raspberry and Go from Source

It looks like FreeBSD on the Odroid does not support floating point. I believe at some point floating point support was added to the broadcom chip in the raspberry pi 2, but I haven't tried to use freebsd on any arm platform since the previous reply to this thread in 2015. On Thu, May 18, 2017 at

Actualy the secret is this GOARM=5 . Seems it impacts also on the error about struct_passwd, somehow. I had GOARM set to 6 because I took the settings from a linux machine (running on ODROID XU4) and it was failing like that. About compilation times of 3 hours, they depend mostly by disk

Hi, Having a default "go" folder inside your home directory is a recent change (I believe it was introduced in 1.8) The mac installer may do extra steps, but my guess is that you started using Go before you set GOPATH to the dropbox folder, a simple go get would create the $HOME/go folder

I don't know about the C1, just because I only own a Odroid XU4. Not sure if there will be a FreeBSD port of it, at all. What I have are 1 Raspi 1, 2 raspi 2 and one ODROID XU4. Actually Freebsd runs only on one Raspi2, and I confirm putting the GOARM to 5 was allowing the bootstrap to

Re: [go-nuts] Why golang garbage-collector not implement Generational and Compact gc?

My feeling is a per-P bump-pointer allocation space can fit into the current go's GMP model for faster allocation than the current allocation path with span calculation and free slot search. But anyway the fragmentation is a big pain. I'm not sure the non-moving property of go GC is the design
