Ivan reported that a simple
$ go get -v -d github.com/FactomProject/factom
Will result in errors when vector instructions are in use. Turns out
golang makes excessive use of vector instructions, e.g., for crypto, hashes
but also basic math.
I tracked the involved vector instructions and started writing more
tests for them (will upstream them once they are in a better shape). Turns
out there are quite some issues remaining. golang uses instructions not
yet used by the kernel or by glibc.
With these patches, "go get" works again. It wouldn't surprise me if there
are more BUGs in the vector instructions. Will continue writing more tests.
