Hi, I'm seeing three build failures in CI: 1. On perf-nofib, it fails with: == make boot -j --jobserver-fds=3,4 --no-print-directory; in /builds/cactus/ghc/nofib/real/smallpt ------------------------------------------------------------------------ /builds/cactus/ghc/ghc/bin/ghc -M -dep-suffix "" -dep-makefile .depend -osuf o -O2 -Wno-tabs -Rghc-timing -H32m -hisuf hi -packageunboxed-ref -rtsopts smallpt.hs <command line>: cannot satisfy -package unboxed-ref (use -v for more information) (e.g. https://gitlab.haskell.org/cactus/ghc/-/jobs/743141#L1465) 2. On validate-x86_64-darwin, pretty much every test fails because of the following extra stderr output: + +<no location info>: + warning: Couldn't figure out C compiler information! + Make sure you're using GNU gcc, or clang (e.g. https://gitlab.haskell.org/cactus/ghc/-/jobs/743129#L3655) 3. On validate-x86_64-linux-deb9-integer-simple, T11545 fails on memory consumption: Unexpected stat failures: perf/compiler/T11545.run T11545 [stat decreased from x86_64-linux-deb9-integer-simple-validate baseline @ 5f3991c7cab8ccc9ab8daeebbfce57afbd9acc33] (normal) This one is interesting because there is already a commit that is supposed to fix this: commit efaad7add092c88eab46e00a9f349d4675bbee06 Author: Matthew Pickering <matthewtpickering@gmail.com> Date: Wed Jul 21 10:03:42 2021 +0100 Stop ug_boring_info retaining a chain of old CoreExpr [...] ------------------------- Metric Decrease: T11545 ------------------------- But still, it's failing. Can someone kick these build setups please? -- .--= ULLA! =-----------------. \ http://gergo.erdi.hu \ `---= gergo@erdi.hu =-------'
