Folks, I'm trying to create a buildbot that would do a great many things, including building clang/llvm/compiler-rt + check-all and libc++/libc++abi + testit, install all that into a prefix and run the test-suite with it. I know ClangBuilder can pull compiler-rt with it, and make check-all would also include its tests. I also know that there is a LibCXXBuilder that can build and test libc++, and that there is an LNTBuilder that can run the test-suite, but I don't know if it's possible to join them all together in one buildbot to rule them all kind of way. Since we have many other buildbots (fast and slow ones), this one could actually take a long time to run (like a day), it doesn't matter that much. But would be good to have a confirmation that the whole toolchain is working in unison for a particular architecture. In the future, I'd like to add an LLD build integrated with this mega-bot, to close the lid on the LLVM Toolchain package. Has it been done? If not, is it possible? cheers, --renato
