Brandon Chinn pushed to branch wip/interpolated-strings-refactor at Glasgow Haskell Compiler / GHC Commits: 4e9297ea by Simon Jakobi at 2026-09-11T08:32:45-04:00 ci: Actually pass --ignore-perf-failures to the testsuite driver 684c0018d9 changed the IGNORE_PERF_FAILURES handling to append to RUNTEST_ARGS with bash array syntax, but the three use sites still expand RUNTEST_ARGS as a scalar, which yields only the first array element. The appended flag was therefore dropped in every job, so perf improvements kept failing Marge Bot batches and master pipelines, contrary to #19562. Append as a string instead, matching the existing --force-colors append in test_hadrian. Fixes #27563.

None of them make sense at the type level, so restriction (R3) of Note [Type data declarations] now covers all of them. Fixes #27732.
