      Improve missing-home-modules warning formatting · 6a7e159c
      Matthew Pickering authored
      Previously the modules were smashed together at the end of the line. As
      the header is quite long, this meant for quite long lines which wrapped
      on smaller terminals.
      
      err msg: A
               B
      
      Now they are nested underneath the long first line of the error message.

      GHCi info: Use src file for cache invalidation · 969e747f
      alexbiehl authored
      Prior to this patch GHCi used the modification time of a module's object
      file to invalidate the info cache.
      
      We now look at the modification time of the source file, if present.

      Fix #14817 by not double-printing data family instance kind signatures · aef2b429
      Ryan Scott authored
      Within `pprDataFamInstDecl`, we were invoking `pprFamInstLHS` to
      pretty-print a data family instance header, and we were passing `Just` a
      kind signature to `pprFamInstLHS` to make it pretty-print the kind
      signature alongside it (this is a consequence of commit
      d1ef223c). But this is silly, because
      then invoke `pp_data_defn`, which //also// pretty-prints the kind
      signature, resulting in the kind signature being printed twice by
      mistake.
      
      This fix is simple—pass `Nothing` to `pprFamInstLHS` instead.

      Tao He authored
      Previously we didn't do exhaustive checking on MultiIf expressions
      and guards in pattern bindings.
      
      We can construct the `LMatch` directly from GRHSs or [LHsExpr]
      (MultiIf's alts) then feed it to checkMatches, without construct the
      MatchGroup and using function `matchWrapper`.

      Move Data.Functor.Contravariant from the contravariant package to base. · 8c7a1551
      Andrew Martin authored
      Move Data.Functor.Contravariant from the contravariant package to base.
      Since base is the bottom of the dependency hierarchy, several instances
      have been removed. They will need to be added to the following packages:
      transformers, StateVar, and possibly tagged. There may not actually have
      been any types from tagged that previous had instanced provided by this
      module though, since it may have only been used for Data.Proxy. Additionally,
      all CPP has been removed. Derived Typeable instances have been removed
      (since Typeable is now automatically derived for everything). The language
      extension Safe is still used, although it is unclear to ATM whether or not
      it is necessary.
      
      This resolves trac issue #14767.

      Make cost centre symbol names deterministic. · d8e47a2e
      shlevy authored
      Previously, non-CAF cost centre symbol names contained a unique,
      leading to non-deterministic object files which, among other issues,
      can lead to an inconsistency causing linking failure when using cached
      builds sourced from multiple machines, such as with nix. Now, each
      cost centre symbol is annotated with the type of cost centre it
      is (CAF, expression annotation, declaration annotation, or HPC) and,
      when a single module has multiple cost centres with the same name and
      type, a 0-based index.

      With a lot of files and many -optP flags, that's a lot

      Slight refactor of stock deriving internals · f4336593
      Ryan Scott authored
      Summary:
      Before, the `hasStockDeriving` function, which determines
      how derived bindings should be generated for stock classes, was
      awkwardly separated from the `checkSideConditions` function, which
      checks invariants of the same classes that `hasStockDeriving` does.
      As a result, there was a fair deal of hoopla needed to actually use
      `hasStockDeriving`.
      
      But this hoopla really isn't required—we should be using
      `hasStockDeriving` from within `checkSideConditions`, since they're
      looking up information about the same classes! By doing this, we can
      eliminate some kludgy code in the form of `mk_eqn_stock'`, which had
      an unreachable `pprPanic` that was stinking up the place.

      Change how includes for input file directory works · eb2daa2b
      Tamar Christina authored
      GHC Used to only allow for one include mode, namely `-I`.  The problem
      with `-I` includes is that it supercedes all other includes, including
      the system include paths.
      
      This is not a problem for paths requested by the user, but it is a
      problem for the ones we implicitly derive and add.
      
      In particular we add the source directory of the input file to the
      include path. This is problematic because it causes any file with the
      name of a system include, to inadvertently loop as the wrong file gets
      included.
      
      Since this is an implicitly include, and as far as I can tell, only done
      so local includes are found (as the sources given to GCC reside in a
      temp folder) then switch from `-I` to `-iquote`.
      
      This requires a submodule update for haddock
