Here's what I got: -- master (a3bce956d7) -- {{{ Unexpected stat failures: /tmp/ghctest-hajvz66w/test spaces/perf/compiler/T9630.run T9630 [stat not good enough] (normal) }}} -- + step 1 (wip/T14880-2-step1) -- {{{ Unexpected stat failures: /tmp/ghctest-shsa0qwp/test spaces/perf/compiler/T9630.run T9630 [stat not good enough] (normal) }}} -- + step 2 (wip/T14880-2-step2-c123) -- {{{ Unexpected failures: /tmp/ghctest-5yp1lu_z/test spaces/dependent/should_fail/BadTelescope4.run BadTelescope4 [exit code 0] (normal) /tmp/ghctest-5yp1lu_z/test spaces/dependent/should_fail/T14066g.run T14066g [exit code 0] (normal) /tmp/ghctest-5yp1lu_z/test spaces/partial- sigs/should_compile/T12844.run T12844 [stderr mismatch] (normal) /tmp/ghctest-5yp1lu_z/test spaces/partial- sigs/should_compile/T15039a.run T15039a [stderr mismatch] (normal) /tmp/ghctest-5yp1lu_z/test spaces/partial- sigs/should_compile/T15039b.run T15039b [stderr mismatch] (normal) /tmp/ghctest-5yp1lu_z/test spaces/partial- sigs/should_compile/T15039c.run T15039c [stderr mismatch] (normal) /tmp/ghctest-5yp1lu_z/test spaces/partial- sigs/should_compile/T15039d.run T15039d [stderr mismatch] (normal) /tmp/ghctest-5yp1lu_z/test spaces/partial-sigs/should_run/T15415.run T15415 [bad stderr] (ghci) /tmp/ghctest-5yp1lu_z/test spaces/polykinds/T14265.run T14265 [stderr mismatch] (normal) }}} -- + step 3 (wip/T14880-2-step3) -- {{{ Unexpected failures: /tmp/ghctest-ht1chu9r/test spaces/dependent/should_compile/T14880-2.run T14880-2 [exit code non-0] (normal) /tmp/ghctest-ht1chu9r/test spaces/dependent/should_fail/BadTelescope4.run BadTelescope4 [exit code 0] (normal) /tmp/ghctest-ht1chu9r/test spaces/dependent/should_compile/dynamic- paper.run dynamic-paper [stderr mismatch] (normal) /tmp/ghctest-ht1chu9r/test spaces/dependent/should_fail/T14066g.run T14066g [exit code 0] (normal) /tmp/ghctest-ht1chu9r/test spaces/partial- sigs/should_compile/T12844.run T12844 [stderr mismatch] (normal) /tmp/ghctest-ht1chu9r/test spaces/partial- sigs/should_compile/T15039a.run T15039a [stderr mismatch] (normal) /tmp/ghctest-ht1chu9r/test spaces/partial- sigs/should_compile/T15039b.run T15039b [stderr mismatch] (normal) /tmp/ghctest-ht1chu9r/test spaces/partial- sigs/should_compile/T15039c.run T15039c [stderr mismatch] (normal) /tmp/ghctest-ht1chu9r/test spaces/partial- sigs/should_compile/T15039d.run T15039d [stderr mismatch] (normal) /tmp/ghctest-ht1chu9r/test spaces/partial-sigs/should_run/T15415.run T15415 [bad stderr] (ghci) /tmp/ghctest-ht1chu9r/test spaces/polykinds/T9222.run T9222 [stderr mismatch] (normal) /tmp/ghctest-ht1chu9r/test spaces/polykinds/T14265.run T14265 [stderr mismatch] (normal) }}} So it seems that step1 doesn't add any regressions beyond what's on master already, but steps 2 and 3 do. Step 3 also fails to pass the additional test `T14880-2` it introduces. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14880#comment:134 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
