Hello!

Could you create a ticket about this with all the relevant details (OS X version, boot ghc version, commit, hadrian command, etc), and the 'hadrian' label? You should even feel free to mention @snowleopard and @alp there.

Any ideas?

Hi Alp,

Just confirming now but it seems its https://gitlab.haskell.org/ghc/ghc/commit/e529c65eacf595006dd5358491d28c202d... where the breakage came in ("Remove all target specific portions of Config.hs" @John Ericson).
