Would it be possible (do we have the resources?) to set up a build and test bot for 32-bit x86 similar to the C Loop LLINT bot?  I would like to run the layout tests on it, but I think that that might require a lot of work to triage test failures that only exists on 32-bit x86 (e.g. webgl issues).  I think a good goal to start with, is to build and run the jsc tests only.  Unlike the C loop LLINT, the 32-bit x86 build should be able to run the full jsc tests and complete in a relative short amount of time still.  Currently, there is a regression (https://bugs.webkit.org/show_bug.cgi?id=130134) that I need to fix first before we can turn this bot on.

To build from open source (we should make this an open source bot):
$ ./Tools/Script/build-jsc —debug —32-bit

To run the tests:
$ ./Tools/Script/run-javascriptcore-tests —debug —32-bit —no-build

I think having this bot will help us notice and fix 32-bit JIT issues (not covered by the C loop LLINT bot) sooner, and avoid regressions that may impact 32-bit ARM on iOS as well.  If we can spare the resource for it, it’ll be great to have such a bot.
