"""Script for running llvm validation tests on ChromeOS.
This script launches a buildbot to build ChromeOS with the llvm on
a particular board; then it finds and downloads the trybot image and the
corresponding official image, and runs test for correctness.
It then generates a report, emails it to the c-compiler-chrome, as
well as copying the result into a directory.
# Script to test different toolchains against ChromeOS benchmarks.
