Travis Notes for Administrators

Administrators: Are PRs taking > 1 hr to run through Travis? If you look at the Travis logs is it building riscv-tools?

This is because someone committed a PR to master which bumped riscv-tools and the master cache needs to be updated. This is the procedure to follow to get things fast again. We don't generally build on merges to master, just PRs.

1. Wait for your PR that you want to merge to go green. This will take a long time.
2. On Travis, click More Options -> Caches on the upper right.
3. Click Delete all Repository Caches.
4. Click More Options->Settings
5. On the General Settings section, switch the Build Branch Updates toggle to ON.
6. perform your PR's merge to master. This will cause the master cache to build riscv-tools.
7. Once the merge commit goes green on Travis, switch the Build Branch Updates toggle to OFF.
