Similarly, I've got a jenkins instance here were I can get a bootstrap and regression test on the usual targets like aarch64, armv7, i686, powerpc (32, 64, 64le), s390x, sparc64, x86_64. But more interestingly it'll also do a bootstrap test on alpha, hppa, m68k, sh4 and other oddballs like aarch64-be.
A patch for the tip of the trunk is all I need. It doesn't run the testsuite, but the ability to bootstrap on the lesser used targets gives a level of code generator validation that is helpful. Takes about 24hrs to cycle through everything... jeff
