      Increase precision of timings reported by RTS · 57ed4101
      Herbert Valerio Riedel authored
      Summary:
      Today's hardware is much faster, so it makes sense to report timings
      with more precision, and possibly help reduce rounding-induced
      fluctuations in the nofib statistics.
      
      This commit increases the precision of all timings previously reported
      with a granularity of 10ms to 1ms. For instance, the `+RTS -S` output is
      now rendered as:

      Implement OVERLAPPING and OVERLAPPABLE pragmas (see #9242) · 97f499b5
      Iavor S. Diatchki authored
      This also removes the short-lived NO_OVERLAP pragama, and renames
      OVERLAP to OVERLAPS.
      
      An instance may be annotated with one of 4 pragams, to control its
      interaction with other overlapping instances:
      
        * OVERLAPPABLE:
          this instance is ignored if a more specific candidate exists
      
        * OVERLAPPING:
          this instance is preferred over more general candidates
      
        * OVERLAPS:
          both OVERLAPPING and OVERLAPPABLE (i.e., the previous GHC behavior).
          When compiling with -XOverlappingInstances, all instance are OVERLAPS.
      
        * INCOHERENT:
          same as before (see manual for details).
          When compiling with -XIncoherentInstances, all instances are INCOHERENT.

      Module reexports, fixing #8407. · 7f5c1086
      Edward Z. Yang authored
      
      
      The general approach is to add a new field to the package database,
      reexported-modules, which considered by the module finder as possible
      module declarations.  Unlike declaring stub module files, multiple
      reexports of the same physical package at the same name do not
      result in an ambiguous import.
      
      Has submodule updates for Cabal and haddock.
      
      NB: When a reexport renames a module, that renaming is *not* accessible
      from inside the package.  This is not so much a deliberate design choice
      as for implementation expediency (reexport resolution happens only when
      a package is in the package database.)
      
      TODO: Error handling when there are duplicate reexports/etc is not very
      well tested.
