Matthew Pickering pushed to branch wip/gbc-files at Glasgow Haskell Compiler / GHC Commits: 33732b36 by Matthew Pickering at 2025-10-10T15:39:29+01:00 Revert "Add a perf test for #26425" This test has a large memory spike currently, which makes the test sensitive, since if you allocate a little more or less, the precise location where GC happens shifts and you observe a different part of the spike. Andreas told me to revert the patch for now, and he will add it back when he fixes the memory spike.
