* Documentation, tests for hsc2hs's new #alignment macroRyanGlScott2015-12-1910-0/+81
| | | | | | | | | | | | | | Adds two tests (one for Trac #4340 and one for Trac #10272), as well as advice on how to fix your code if `hsc2hs` emits warnings with GHC 8.0 due to a redefinition of `#alignment`. (I also put the advice in the [GHC 8.0 Migration Guide](https://ghc.haskell.org/trac/ghc/wiki/Migration/8.0).)

* SrcLoc: Eliminate constructors of RealSrcSpanBen Gamari2015-12-181-55/+40
| | | | | | | | | | | | | | This type is occurs very often but previously had multiple, meaning it could not be unboxed. Even worse, these constructors didn't offer any compelling safety benefits. Thankfully, the type is abstract, so changing the representation to be a single-constructor type was quite straightforward.

* tcCheckSatisfiability: less aggressive superclass expansionSimon Peyton Jones2015-12-184-16/+161
| | | | | | | | | | | | | | In the pattern-match check we are looking for a proof of *unsatisfiablity* among a bunch of givens. The unsat-ness might be hidden in the superclasses, so we must expand them. But in the common case where the constraints are satisfiable, we don't want to expand a recursive superclass forever. This is all a bit arbitrary, but then the whole question is undecidable anyway. The bug in Trac #10592 comment:12 was that I expanded superclasses forever. This patch fixes it.

* Move Data.Functor.(Classes,Compose,Product,Sum) into baseRyanGlScott2015-12-178-1/+753
| | | | | | | | | | | | | | | These modules were previously provided by the `transformers` package. Hence the submodule update. This patch was originally contributed by M Farkas-Dyck and subsequently taken over and completed by Ryan. The original proposal discussion can be found at https://mail.haskell.org/pipermail/libraries/2015-July/026014.html This addresses #11135 Differential Revision: https://phabricator.haskell.org/D1543

* Testsuite: allow spaces in TEST_HC passed in by the userThomas Miedema2015-12-171-17/+13
| | | | | | | | | | | | | | | | Don't use the GNU make function 'realpath' (reverting e66a81c6), because it doesn't handle spaces in paths. Instead, use 'cygpath' to convert Windows style paths (e.g. C:/foo/) to mingw style paths (e.g. c/foo/), and then call 'which'. Tests: * make TEST_HC=ghc * make TEST_HC=/d/home/thomie/ghc-validate/bindisttest/install\ \ \ dir/bin/ghc * make TEST_HC=D:/home/thomie/ghc-validate/bindisttest/install\ \ \ dir/bin/ghc Reviewed by: Phyx Differential Revision: https://phabricator.haskell.org/D1431

* Fix #11230.Richard Eisenberg2015-12-175-6/+42

* Fix tcTyClTyVars to handle SigTvsRichard Eisenberg2015-12-173-63/+130
| | | | | | | | | | | | | | Previously, tcTyClTyVars required that the names of the LHsQTyVars matched up exactly with the names of the kind of the given TyCon. It now does a bit of matching up when necessary to relax this restriction. This commit enables a few tests that had previously been disabled. The shortcoming this addresses is discussed in #11203, but that ticket is not directly addressed here. Test case: polykinds/SigTvKinds, perf/compiler/T9872d

* Reify DuplicateRecordFields by label, rather than by selectorAdam Gundry2015-12-176-3/+95
| | | | | | | | | | | | | | | | | | | | | | | See `Note [Reifying field labels]` in `TcSplice`. This makes typical uses of TH work better with `DuplicateRecordFields`. If `reify` is called on the `Name` of a field label produced by the output of a previous `reify`, and there are multiple fields with that label defined in the same module, it may fail with an ambiguity error. Test Plan: Added tests, and manually tested that this makes Aeson's `deriveJSON` avoid the `$sel:` prefixes.
