This is an implementation of the deprecated exports proposal #134. The proposal introduces an ability to introduce warnings to exports. This allows for deprecating a name only when it is exported from a specific module, rather than always depreacting its usage. In this example: module A ({-# DEPRECATED "do not use" #-} x) where x = undefined --- module B where import A(x) `x` will emit a warning when it is explicitly imported. Like the declaration warnings, export warnings are first accumulated within the `Warnings` struct, then passed into the ModIface, from which they are then looked up and warned about in the importing module in the `lookup_ie` helpers of the `filterImports` function (for the explicitly imported names) and in the `addUsedGRE(s)` functions where they warn about regular usages of the imported name. In terms of the AST information, the custom warning is stored in the extension field of the variants of the `IE` type (see Trees that Grow for more information). The commit includes a bump to the haddock submodule added in MR #28 Signed-off-by:

Problem: In 2463df2f, the Solo data constructor was renamed to MkSolo, and Solo was turned into a pattern synonym for backwards compatibility. Since pattern synonyms can not be promoted, the old code that pretty-printed promoted single-element tuples started producing ill-typed code: t :: Proxy ('Solo Int) This fails with "Pattern synonym ‘Solo’ used as a type" The solution is to track the distinction between type constructors and data constructors more carefully when printing single-element tuples.

Before this patch, GHC unconditionally printed ticks before promoted data constructors: ghci> type T = True -- unticked (user-written) ghci> :kind! T T :: Bool = 'True -- ticked (compiler output) After this patch, GHC prints ticks only when necessary: ghci> type F = False -- unticked (user-written) ghci> :kind! F F :: Bool = False -- unticked (compiler output) ghci> data False -- introduce ambiguity ghci> :kind! F F :: Bool = 'False -- ticked by necessity (compiler output) The old behavior can be enabled by -fprint-redundant-promotion-ticks. Summary of changes: * Rename PrintUnqualified to NamePprCtx * Add QueryPromotionTick to it * Consult the GlobalRdrEnv to decide whether to print a tick (see mkPromTick) * Introduce -fprint-redundant-promotion-ticks Co-authored-by:Artyom Kuznetsov <hi@wzrd.ht>

This patch fixes pretty-printing of character literals inside promoted lists and tuples. When we pretty-print a promoted list or tuple whose first element starts with a single quote, we want to add a space between the opening bracket and the element: '[True] -- ok '[ 'True] -- ok '['True] -- not ok If we don't add the space, we accidentally produce a character literal '['. Before this patch, pprSpaceIfPromotedTyCon inspected the type as an AST and tried to guess if it would be rendered with a single quote. However, it missed the case when the inner type was itself a character literal: '[ 'x'] -- ok '['x'] -- not ok Instead of adding this particular case, I opted for a more future-proof solution: check the SDoc directly. This way we can detect if the single quote is actually there instead of trying to predict it from the AST. The new function is called spaceIfSingleQuote.

GHC tests the exact print annotations using the contents of utils/check-exact. The same functionality is provided via https://github.com/alanz/ghc-exactprint The latter was updated to ensure it works with all of the files on hackage when 9.2 was released, as well as updated to ensure users of the library could work properly (apply-refact, retrie, etc). This commit brings the changes from ghc-exactprint into GHC/utils/check-exact, adapting for the changes to master. Once it lands, it will form the basis for the 9.4 version of ghc-exactprint. See also discussion around this process at #21355

Continue to prune the `Language.Haskell.Syntax.*` modules out of GHC imports according to the plan in the linked issue. Moves more GHC-specific declarations to `GHC.*` and brings more required GHC-independent declarations to `Language.Haskell.Syntax.*` (extending e.g. `Language.Haskell.Syntax.Basic`).

The ghc-exactPrint library has had to re-introduce the relatavise phase. This is needed if you change the length of an identifier and want the layout to be preserved afterwards. It is not possible to relatavise a bare SrcSpan, so introduce `SrcAnn NoEpAnns` for them instead. Updates haddock submodule.

The EpaAnnCO we were using contained an Anchor instead of EpaLocation, making it harder to work with. At the same time, using EpaLocation by itself isn't possible either, as we may have tokens without location information.
