Simon Jakobi pushed to branch wip/sjakobi/T25450-march-native at Glasgow Haskell Compiler / GHC Commits: a0369c82 by Simon Jakobi at 2026-06-02T13:59:36+02:00 Mark -march=native as expected-undocumented for the flag linter --show-options emits the full token "-march=native", but compare-flags.py strips documented flags at "=", so the ghc-flag directive reduces to "-march" and never matches. List the full token here, consistent with other value-variant flags such as -rtsopts=all and -fdiagnostics-color=always. Issue reported in #27321.
