--- Comment #4 from Mark Wielaard <mark at gcc dot gnu.org> --- The slowdown is on the pioneer box, which has 64 cores and 128GB ram. https://builder.sourceware.org/buildbot/#/builders/gcc-full-fedora-riscv See the build times tab on that page. It used to do builds in 4 to 5 hours (it slowly increased in the last month) (bootstrap, make -j64 in ~2.5 hours, plus tests, make -j64 check in ~1.5 hours) But recently jumped to ~9 hours (bootstrap, make -j64 in ~7.5 hours, plus tests, make -j64 check in ~1.5 hours) And in the last day it kept timing out trying to build insn-attrtab.cc for more than 2.5 hours.
