Maybe I'm in the minority but I would rather have resources devoted to improving compile times in 1.5+ versions vs. having golang work on arm.

Isn't the best course usually to build a solid foundation, then branch out?

It's incredible to run buildall.sh on a recent go repo and see all the cross-compilers get built with no fuss or hassle. There are at least 30 different target platforms I can get to from my ubuntu box with a single command line.

I'm not aware of anything that even comes close to tooling out cross compilation so easily.

I, too, would like compile and lint times faster, ideally a lot faster.

That said, the counterpoint is that cross-compilation is not something you can easily bolt on later -- if you aren't doing, and testing it along the way, you will never be able to add it back in. It needs to be there from the beginning and stay a first-class support goal, otherwise mistakes, good intentions and laziness will all yield a product that just can't easily make the leap back to solid cross compilation with no hassle.

This is for both development on ARM systems (standard go commands, eg: go build, etc) and deploying to ARM systems (setting ARM as a compile target). That said, I'm genuinely curious why anyone would develop on an ARM-based system as opposed to your run of the mill desktop.

I realize that standard towers may be supplanted by their SoC brethren, but so what? Will we all be using iMac-like computers as desktops in the next 36-72 months? Will there even be any differentiation between "regular" desktops with discrete CPUs, memory, etc and the system-on-a-chip variant?

ARM is really important. It's probably the fastest growing architecture other than x86 where people use things like this.

I'd also like to see Go on MIPS64, though probably less important than ARM.

Not everybody compiles all binaries they deploy on developer workstations. If you run ARM servers, it makes sense that your build servers are on ARM as well, especially since you should run tests on the same architecture you're deploying to.

Really? I know 1.5 is slower than previous versions, but it's still by far the fastest compiler I've ever worked with.
