On my buildbots I try and update the compiler once a week or so.

Perhaps we ought to have nightly (or whatever appropriate > frequency) clean builds in addition to such a ccache bot. Very good point. As I understand it, this should only matter when the compiler changes. I'll make sure to clear the cache entirely when updating the compilers.

As it currently stands that wouldn't work. cxx_under_test is expected to be a single token. I understand concerns about this setup being fragile. However I would still like to try it out on my bots for the time being. There are a number of extra configurations I would like to run and currently I don't have the resources to do it. My OSX builder takes 30-45 minutes per run. It would be nice to get this down. http://reviews.llvm.org/D6647 EMAIL PREFERENCES http://reviews.llvm.org/settings/panel/emailpreferences/ _______________________________________________ cfe-commits mailing list [email protected] http://lists.cs.uiuc.edu/mailman/listinfo/cfe-commits
