Apoorv Ingle pushed to branch wip/ani/T27156 at Glasgow Haskell Compiler / GHC Commits: 576987d0 by Simon Jakobi at 2026-06-02T04:53:36-04:00 compiler: use nubOrd from containers Address #27103 by replacing GHC.Utils.Misc.ordNub[On] with Data.Containers.ListUtils.nubOrd[On]. Note that nubOrd suffers from a small inefficiency, a fix for which will be included in the next containers release: https://github.com/haskell/containers/issues/1202 - - - - - deea53c3 by David Eichmann at 2026-06-02T04:54:22-04:00 Hadrian: disable response files for GHC/Haddock builders on non-Windows This makes debugging build errors easier on non-windows hosts.

This patch introduces a variant of mkTick that skips the single optimisation that could break ANF. This is preferrable over switching to the raw Tick constructor, as the latter may introduce spurious cost centres in profiling reports. This is a temporary measure until we more thoroughly refactor how mkTick works (see #27141). See Note [mkTick breaks ANF] in GHC.CoreToStg.Prep.

Convert ACLOCAL_PATH to a unix style path when invoking autoreconf. Autoreconf doesn't handle windows paths. See Note [Autoreconf unix paths from ACLOCAL_PATH]. Fixes #27311 - - - - - 18f6138a by Simon Jakobi at 2026-06-04T20:20:31-04:00 testsuite: Deduplicate --only test names config.only is assumed to be a set, but supplying --only overwrote it with the (list) argparse result, which can contain duplicates. When a test ran, config.only.remove(name) dropped only the first occurrence, so a duplicated name lingered and was later misreported as a "test not found" framework failure. Store it as a set instead.

That error went to stderr and leaked into the captured stderr of every makefile_test, causing spurious [bad stderr] failures across the suite. The probe also silently returned empty, so config.have_fast_bignum was wrongly False even on GMP builds. Probe ghc-internal's extra-libraries for the gmp library instead: the GMP backend module is an other-module (not exposed), but GMP_LIBS adds gmp to extra-libraries only on a GMP build, so this distinguishes the backends. Redirect stderr to keep any future missing-package error off the harness's stderr. This also removes a stale comment as per suggestion from hsyl20.
