Testing LLVM

I always find committing to LLVM very nerve wrecking, because of the post-commit CI testing. LLVM has so many architectures that more often than not something I write will fail on one of them. And the only way for me to find out is to commit it, wait for the buildbot to fail (which can take a few hours, during which I really can't leave my computer lest I leave trunk broken on some buildbot, which is a big faux pas), revert it and then figure out what went wrong. I'm hoping that at some point this will be improved, such that I can run the whole buildbot army on my commit before putting it on trunk.

Interesting to see screenshots of LCOV. I'm hoping to get an intern to work on test coverage this summer, and I wondered whether LCOV is still current. Looks like the latest release is from December 2016.

<i>&quot;Compilers are usually not networked, concurrent, or timing-dependent, and overall interact with the outside world only in very constrained ways.&quot;</i><p>Are there any parallel compliers?

One quirk of llvm is that they don&#x27;t have a pre-commit CI.

I do find it strange that such a large project isn&#x27;t using a better VCS. SVN seems to be very antiquated.
