Deploying the rust compiler to Blue Gene

Luckily for us, powerpc64-unknown-linux-gnu is a supported target triple, and we can download the toolchain through rustup.

If a firewall prevents the use of rustup on the remote machine, you can download the toolchain on your own machine

[ lampam@arch-t430s ] ~
$ rustup toolchain add 1.20.0-powerpc64-unknown-linux-gnu
$ cd ~/.rustup/toolchains/1.20.0-powerpc64-unknown-linux-gnu/

Testing setup

I improved my testing setup a bit from what I used in this comment. Now you can see when argdebug gets called multiple times.

$HOME/bin/argdebug

#!/bin/sh
echo >&2 'argdebug'
for x in "$@"; do
