Hi, the attached graph shows a noticable increase in build time caused by Update Cabal submodule & ghc-pkg to use new module re-export types author Edward Z. Yang <ezyang@cs.stanford.edu> https://git.haskell.org/ghc.git/commit/4b648be19c75e6c6a8e6f9f93fa12c7a4176f... and only halfway mitigated by Update `binary` submodule in an attempt to address #9630 author Herbert Valerio Riedel <hvr@gnu.org> https://git.haskell.org/ghc.git/commit/3ecca02516af5de803e4ff667c8c969c5bffb... I am not sure if the improvement is related to the regression, but in any case: Edward, was such an increase expected by you? If not, can you explain it? Can it be avoided? Or maybe Cabal just became much larger... +38% in allocations when running haddock on it seems to confirm this.
