* Check that libs found by GCC aren't foldersAlec Theriault2019-01-071-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: We use 'gcc -B<base-location> --print-file-name mylib.a' as a way of checking if 'gcc' can discover 'mylib.a' at the given location. However, this can break down if there is a folder caller 'mylib.a' that 'gcc' can discover. We can guard against this by explicitly checking that the path returned by 'gcc' is a file. This may seem like a far-fetched scenario, but since 3d17f1f10fc00540ac052f2fd03182906aa47e35, we look for libraries without any prefix or suffix (ie. 'extra-libraries: softfloat', we look for just 'softfloat' as well as 'softloat.a', 'softfloat.dll.a', etc.) which means that there might actusally be a folder of that name in one of the base locations.

* Visible kind applicationmynguyen2019-01-0323-526/+889
| | | | | | | | | | | | | | | | | | | | | | | Summary: This patch implements visible kind application (GHC Proposal 15/#12045), as well as #15360 and #15362. It also refactors unnamed wildcard handling, and requires that type equations in type families in Template Haskell be written with full type on lhs. PartialTypeSignatures are on and warnings are off automatically with visible kind application, just like in term-level. There are a few remaining issues with this patch, as documented in ticket #16082. Includes a submodule update for Haddock.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Trac #16038 exposed the fact that TcRnDriver.checkHiBootIface was creating a binding, in the module being compiled, for $fxBlah = $fBlah but $fxBlah was a /GlobalId/. But all bindings should be for /LocalIds/ else dependency analysis goes down the tubes. * I added a CoreLint check that an occurrence of a GlobalId is not bound by an binding of a LocalId. (There is already a binding-site check that no binding binds a GlobalId.) * I refactored (and actually signficantly simplified) the tricky code for dfuns in checkHiBootIface to ensure that we get LocalIds for those boot-dfuns. Alas, I then got "duplicate instance" messages when compiling HsExpr. It turns out that this is a long-standing, but extremely delicate, bug: even before this patch, if you compile HsExpr with -ddump-tc-trace, you get "duplicate instance". Without -ddump-tc-trace, it's OK. What a mess! The reason for the duplicate-instance is now explained in Note [Loading your own hi-boot file] in LoadIface. I fixed it by a Gross Hack in LoadIface.loadInterface. This is at least no worse than before. But there should be a better way. I have opened #16081 for this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: GHCi's `:info` command was pretty-printined GADT constructors suboptimally in the following ways: 1. Sometimes, fields were parenthesized when they did not need it, e.g., ```lang=haskell data Foo a where MkFoo :: (Maybe a) -> Foo a ``` I fixed this by refactoring some code in `pprIfaceConDecl` to be a little smarter with respect to GADT syntax. See `pprFieldArgTy` and `pprArgTy`. 2. With `-fprint-explicit-kinds` enabled, there would be times when specified arguments would be printed without a leading `@` in GADT return types, e.g., ```lang=haskell data Bar @k (a :: k) where MkBar :: Bar k a ``` It turns out that `ppr_tc_app`, the function which pretty-prints these return types, was not using the proper machinery to print out the arguments, which caused the visibilities to be forgotten entirely. I refactored `ppr_tc_app` to do this correctly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Allow GHCi to not crash when no assumed DLL is found in the standard location. E.g. when loading the package built "dyn" way, we may well have the package's DLL around, and it's the system linker which loads necessary dependencies. Why does this (partially) fix #11042? It's because we often (and when having packages built `dyn` way -- almost always) don't need to load anything recorded in the `extra-libraries` stanza, since if the package DLL exists, GHCi linker simply calls the system linker (via `dlopen`/ `LoadLibrary` APIs) to load it and doesn't bother to load package prelinked object file (if any) or package static library. Thus, all "regular" (with no fancy low-level package content manipulation) packages built "dyn" way should be OK after this fix.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously datacon strictness was accounted for when we demand analysed a case analysis. However, this results in pessimistic demands in some cases. For instance, consider the program (from T10482) data family Bar a data instance Bar (a, b) = BarPair !(Bar a) !(Bar b) newtype instance Bar Int = Bar Int foo :: Bar ((Int, Int), Int) -> Int -> Int foo f k = case f of BarPair x y -> case burble of True -> case x of BarPair p q -> ... False -> ... We really should be able to assume that `p` is already evaluated since it came from a strict field of BarPair. However, as written the demand analyser can not conclude this since we may end up in the False branch of the case on `burble` (which places no demand on `x`). By accounting for the data con strictness later, applied to the demand of the RHS, we get the strict demand signature we want. See Note [Add demands for strict constructors] for a more comprehensive discussion.
