Building chromium on an icecc cluster

Prerequisites

A chromium checkout on a Linux computer
ccache
icecc version >= 1.1rc2.
A functioning icecc cluster and a running iceccd on the local computer

Setup

Add repo root directory to $PATH
source ccache-env
Add custom hook to .gclient. See documentation in icecc-create-env.py
Run gclient runhooks

Usage

Build with icecc-ninja instead of ninja. For instance:

icecc-ninja -j64 -C out/Release blink_tests

Issues

Using clang plugins does not work. They are disabled in icecc.gni which means that e.g. some oilpan errors will go unnoticed.

From time to time there are compile errors which only happen when distributed with icecc. I have seen at least the avx512 issue mentioned in [1]. A workaround for that without messing with local patches is to run ninja instead of icecc-ninja for the problematic target(s).
