      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.

      forkProcess: fix task mutex release order · e261b852
      Ömer Sinan Ağacan authored
      `all_tasks_mutex` should be released before calling `releaseCapability_`
      in the parent process as `releaseCapability_` spawns worker tasks in
      some cases.

      Cache the fingerprint of sOpt_P · b8f03bbe
      niteria authored
      Before this change we would compute a hash of
      all the command line -optP flags once per file.
      With a lot of files and many -optP flags, that's a lot
      of repeated work.
      I added a new Note that explains the approach and rationale.

      Slight refactor of stock deriving internals · f4336593
      Ryan Scott authored
      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
      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
      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

      Sadly it's not immediately obvious where this regression came from:
       * T5837 started failing on OS X with 0c2350c2
       * It's not clear when T1969 started failing due to the recent out of memory
