Bug#950517: golang-1.14: please add support for riscv64

[Aurelien Jarno]

Source: golang-1.14
Version: 1.14~beta1-2
Severity: wishlist
Tags: patch

Hi,

golang 1.14 will add support for the 64-bit RISC-V architecture, aka
riscv64. It has been committed upstream over the last days.

On the Debian packaging side, it requires very few changes. See the
attached patch. With it and with a git snapshot from today, I have been
able to bootstrap golang. Unfortunately bootstrapping it from gcc-go
didn't work, one of the go1 process never ends. It's probably a GCC bug.
Instead I have followed the process from Carlos Eduardo [1] to bootstrap
it from amd64, and then build it natively. All seems to work fine.

Would it be possible to include that patch in the next golang-1.14
upload?

Thanks,
Aurelien
