Hello, Freebsd-hackers. I need to rebuild world and kernel often for experiments with NanoBSD, and I want to use clang. But clang bootstrap is drastically slow. And second clang build is not any faster. Whole "buildworld" with lots of parts, like gcc toolchain, games, examples, etc., switched off, takes about 90 (!) minutes in my case. And I don't need "in world" clang too, as it will not be installed on target device. My build host is very closely related to sources which I build -- both are amd64 CURRENT, build host is not as fresh as sources for NanoBSD, but clang is always the same (I rebuild host on every clang change). Is it possible to build NanoBSD faster? Use system compiler, and don't build bootstrap compiler at all? -- // Black Lion AKA Lev Serebryakov <lev@FreeBSD.org>
