What version of Go are you using (go version)?
go version devel +149ac34 Mon May 9 17:50:29 2016 +0000 linux/ppc64le
What operating system and processor architecture are you using (go env)?
GOARCH="ppc64le"
GOOS="linux"
What did you do?
I noticed that the current port for Power does not support vector (VMX/Altivec) registers and instructions.
What did you expect to see?
Vector registers and instructions support are important to enable performance optimization for runtime packages on Power. Those should be implemented.
I have a change to add the initial support for the VMX instructions, starting with the vector registers and X-form load/store instructions.

Related to this work, I was not able to find much documentation about the golang ABI for ppc64x in general and how it affects the VMX registers in particular.
