[llvm-dev] 32-bit Architectures no longer tested by any buildbots causing bitrot

[Peter Smith via llvm-dev]

Hello everyone,

Just to save you some effort. There are a quite a few Arm buildbots including armhf running on http://lab.llvm.org:8011/#/builders maintained by Linaro. For example: clang-cmake-armv7-full . More bots are always welcome though particularly if they are checking a different configuration.

I think there has been some buildbot maintenance recently, and the interface has completely changed since I last looked. There is a possibility that they missed this particular issue, or it was ignored which can happen if the failure isn't reproducible locally on a non Arm machine. If the bots aren't running properly will be worth pinging the maintainer.

Peter

I'm working to set up a build bot for the upcoming M68k target which is 32 bits. And while
I'm at it, I can also set up build bots for 32-bit MIPS, 32-bit PowerPC and 32-bit ARM.

We need these targets in Debian and openSUSE, so I'm happy to help with this effort.

We also need the SPARC target and we have enough SPARC hardware idling and waiting for
work, so that would be a perfect application as well.

I need to become familiar with the build bot setup first as I have not done this before,
so if someone experienced with those bots is willing to assist me, that would be great.

Adrian
