@rnk Could you possibly post build metrics for Chromium (for the whole build process, compilation and link) with and without ghash?
In my early tests, it seemed that on a large project, compilation was a bit slower overall, but linking was faster.
If that still holds, enabling ghash seems only useful when iterating, given you have a good caching mecanism in your build system.
