* Generalize to support arbitrary theories.decision-procedureIavor S. Diatchki2013-10-192-681/+289
| | | | The theory of natural numbers is defined in TcTypeNats.
* Hook-up an SMT solver.Iavor S. Diatchki2013-10-174-14/+738
| | | | | | | | NOTE: This uses a very naive method to call the SMT solver: * GHC will call a program called cvc4, which better be an SMT solver, which is in the path * GHC will create (overwrite!) two files "ghc_input.smt" and "ghc_output,smt" two files in the current directory.

* Fix mkdirhier.sh on OS X 10.9 (#8139)Darin Morrison2013-10-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Mac OS X 10.9 mkdir is apparently stricter than the Mac OS X 10.8 mkdir about which paths are considered valid arguments. For example, in a typical build on Mac OS X 10.9, the first of the following invocations of mkdirhier.sh will succeed but the second will fail: "inplace/bin/mkdirhier" utils/ghc-cabal/dist/build/tmp//. # WORKS "inplace/bin/mkdirhier" bootstrapping/. # FAILS Simply prefixing the path arguments with "./" causes both to succeed: "inplace/bin/mkdirhier" ./utils/ghc-cabal/dist/build/tmp//. # WORKS "inplace/bin/mkdirhier" ./bootstrapping/. # WORKS Testing indicates failure on paths satisfying all of these criteria: - path is suffixed with "/." - path is only 1 level deep (e.g., "foo/."; _not_ "foo/bar/.") - path is _not_ prefixed with "./" This workaround prefixes "./" to the path argument passed to mkdir.

* Update and clean-up the implmenation of GHC.TypeLitsIavor S. Diatchki2013-10-096-109/+131
| | | | | | | | | | | | | | | | | | * Replace class `SingI` with two separate classes: `KnownNat` and `KnownSymbol` * Rename `magicSingId` to `magicDictId`. * Simplify and clean-up the "magic" implementation. This version makes a lot more sense, at least to me :-) * Update notes about how it all works: Note [KnownNat & KnownSymbol and EvLit] explains the evidence for the built-in classes Note [magicDictId magic] explains how we coerce singleton values into dictionaries. This is used to turn run-time integers and strings into Proxy singletons of unknwon type (using an existential).

* Nuke {save,restore}StaticFlagGlobals.Austin Seipp2013-10-092-21/+20
| | | | | | | | | | | | | | | | | | | As discussed in #8276, this code was somewhat broken because while you could always revert the actual argument list, you can never revert the CAFs upon which they are based - so really this didn't buy you much. However, Haddock in particular expects to be able to parse GHC flags, including static flags, and used this code to do so. In its place, we instead have discardStaticFlags, which will safely remove any of the remaining 5 flags from a list of arguments. Haddock instead discards these, as they aren't related to anything it does anyway (mostly controlling debugging output and some basic optimizer phases.) This fixes #8276. In the future, we will eventually completely remove the remaining StaticFlags, removing the need for this fix. Unfortunately these changes will be quite invasive and require more time.

* Use evaldUnfolding for proxyHashIdAustin Seipp2013-10-091-6/+11
| | | | | | | | | | | | Edward and I noticed this - like realWorld#, we want things applied to proxy# which are INLINE more likely to be inlined - we do this by marking proxy# as having an evaldUnfolding, which in turn makes it look like the primitive is evaluated and makes the simplifier more willing to do so. See Note [evaldUnfoldings] in MkId. Signed-off-by: Austin Seipp <austin@well-typed.com>

| * Change the types of typed brackets and splices.Geoffrey Mainland2013-10-042-9/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The essence of this change is that a TExp a now wraps a TH.Exp instead of a TH.ExpQ. This means: * A typed bracket [||...||] now has type Q (TExp tau), where tau is the type of the expression in the bracket. * A typed splice $(...) must contain a value of type Q (TExp tau), and has type tau. Previously, typed brackets had type TExp tau, and typed splices had to contain a value of type TExp tau.
