--- Comment #9 from Eric Gallager <egallager at gcc dot gnu.org> --- (In reply to Sam James from comment #8) > Using make synchronisation can help a bit: > https://www.gnu.org/software/make/manual/html_node/Parallel-Output.html. > It's made our build logs in Gentoo a lot more readable for GCC, FWIW. So, I'm finally getting around to trying this, and it makes it seem as if the testsuite is hanging while waiting for output to be synchronized...
