Not currently relevant, as we don't have Nested\n CPR yet.\n- `T13380f`: Demonstrating unsoundness of the \"IO hack\" for safe FFI\n calls.\n\nBasically, the IO hack assumed that precise exceptions can only be\nthrown from a case scrutinee of type `(# State# RealWorld, _ #)`. I\ncouldn't come up with a program using the `IO` abstraction that violates\nthis assumption. But it's easy to do so via manual state token threading\nand direct use of primops, see `T13380d`. Also similar code might be\ngenerated by Nested CPR in the (hopefully not too) distant future, see\n`T13380e`. Hence, we now have a more careful test in `forcesRealWorld`\nthat passes `T13380{d,e}` (and will hopefully be robust to Nested CPR).\n\n**Precise exceptions**\n\nIn #13380 and #17676 we saw that we didn't preserve precise exception\nsemantics in demand analysis. We fixed that with minimal changes in\n!2956, but that was terribly unprincipled.\n\nThat unprincipledness resulted in a loss of precision, which is tracked\nby these new test cases:\n\n- `T13380b`: Regression in dead code elimination, because !2956 was too\n syntactic about `raiseIO#`\n- `T13380c`: No need to apply the \"IO hack\" when the IO action may not\n throw a precise exception (and the existing IO hack doesn't\n detect that)\n\nFixing both issues in !3014 turned out to be too complicated and had\nthe potential to regress in the future. Hence we decided to only fix\n`T13380b` and augment the `Divergence` lattice with a new middle-layer\nelement, `ExnOrDiv`, which means either `Diverges` (, throws an\nimprecise exception) or throws a *precise* exception.\n\nSee the wiki page on Step 2.1 for more implementational details:\nhttps://gitlab.haskell.org/ghc/ghc/wikis/fixing-precise-exceptions#dead-code-elimination-for-raiseio-with-isdeadenddiv-introducing-exnordiv-step-21\n\n",

Thankfully, it's\npossible to remove one `Maybe` argument from each of these functions,\nwhich this patch accomplishes:\n\n* `bindHsQTyVars` takes a `Maybe SDoc` argument, which is `Just` if\n GHC should warn about any of the quantified type variables going\n unused. However, every call site uses `Nothing` in practice. This\n makes sense, since it doesn't really make sense to warn about\n unused type variables bound by an `LHsQTyVars`. For instance, you\n wouldn't warn about the `a` in `data Proxy a = Proxy` going unused.\n\n As a result, I simply remove this `Maybe SDoc` argument altogether.\n* `bindLHsTyVarBndrs` also takes a `Maybe SDoc` argument for the same\n reasons that `bindHsQTyVars` took one. To make things more\n confusing, however, `bindLHsTyVarBndrs` also takes a separate\n `HsDocContext` argument, which is pretty-printed (to an `SDoc`) in\n warnings and error messages.\n\n In practice, the `Maybe SDoc` and the `HsDocContext` often contain\n the same text. See the call sites for `bindLHsTyVarBndrs` in\n `rnFamInstEqn` and `rnConDecl`, for instance. There are only a\n handful of call sites where the text differs between the\n `Maybe SDoc` and `HsDocContext` arguments:\n\n * In `rnHsRuleDecl`, where the `Maybe SDoc` says \"`In the rule`\"\n and the `HsDocContext` says \"`In the transformation rule`\".\n * In `rnHsTyKi`/`rn_ty`, where the `Maybe SDoc` says\n \"`In the type`\" but the `HsDocContext` is inhereted from the\n surrounding context (e.g., if `rnHsTyKi` were called on a\n top-level type signature, the `HsDocContext` would be\n \"`In the type signature`\" instead)\n\n In both cases, warnings/error messages arguably _improve_ by\n unifying making the `Maybe SDoc`'s text match that of the\n `HsDocContext`. As a result, I decided to remove the `Maybe SDoc`\n argument to `bindLHsTyVarBndrs` entirely and simply reuse the text\n from the `HsDocContext`. (I decided to change the phrase\n \"transformation rule\" to \"rewrite rule\" while I was in the area.)\n\n The `Maybe SDoc` argument has one other purpose: signaling when to\n emit \"`Unused quantified type variable`\" warnings. To recover this\n functionality, I replaced the `Maybe SDoc` argument with a\n boolean-like `WarnUnusedForalls` argument.

This patch serves to clean up\nthis sad state of affairs somewhat. The main change is not in the\ncode itself, but in the documentation, as this patch introduces two\nsections to the GHC User's Guide:\n\n* A \"Formal syntax for GADTs\" section that presents a BNF-style\n grammar for what is and isn't allowed in GADT constructor types.\n This mostly exists to codify GHC's existing behavior, but it also\n imposes a new restriction that addresses #18191: the outermost\n `forall` and/or context in a GADT constructor is not allowed to be\n surrounded by parentheses.

Surprisingly, there was\n no mention of this anywhere in the User's Guide up until now!\n\nTo adhere the new specification in the \"Formal syntax for GADTs\"\nsection of the User's Guide, the following code changes were made:\n\n* A new function, `GHC.Hs.Type.splitLHsGADTPrefixTy`, was introduced.\n This is very much like `splitLHsSigmaTy`, except that it avoids\n splitting apart any parentheses, which can be syntactically\n significant for GADT types. See\n `Note [No nested foralls or contexts in GADT constructors]` in\n `GHC.Hs.Type`.\n\n* `ConDeclGADTPrefixPs`, an extension constructor for `XConDecl`, was\n introduced so that `GHC.Parser.PostProcess.mkGadtDecl` can return\n it when given a prefix GADT constructor. Unlike `ConDeclGADT`,\n `ConDeclGADTPrefixPs` does not split the GADT type into its argument\n and result types, as this cannot be done until after the type is\n renamed (see `Note [GADT abstract syntax]` in `GHC.Hs.Decls` for why\n this is the case).\n\n* `GHC.Renamer.Module.rnConDecl` now has an additional case for\n `ConDeclGADTPrefixPs` that (1) splits apart the full `LHsType` into\n its `forall`s, context, argument types, and result type, and\n (2) checks for nested `forall`s/contexts. Step (2) used to be\n performed the typechecker (in `GHC.Tc.TyCl.badDataConTyCon`) rather\n than the renamer, but now the relevant code from the typechecker\n can simply be deleted.\n\n One nice side effect of this change is that we are able to give a\n more accurate error message for GADT constructors that use visible\n dependent quantification (e.g., `MkFoo :: forall a -> a -> Foo a`),\n which improves the stderr in the `T16326_Fail6` test case.\n\nFixes #18191. Bumps the Haddock submodule.\n\n",
"a47e6442bc4be4a33339499d876792ba109e8d32": "Always use rnImplicitBndrs to bring implicit tyvars into scope\n\nThis implements a first step towards #16762 by changing the renamer\nto always use `rnImplicitBndrs` to bring implicitly bound type\nvariables into scope. The main change is in `rnFamInstEqn` and\n`bindHsQTyVars`, which previously used _ad hoc_ methods of binding\ntheir implicit tyvars.\n\nThere are a number of knock-on consequences:\n\n* One of the reasons that `rnFamInstEqn` used an _ad hoc_ binding\n mechanism was to give more precise source locations in\n `-Wunused-type-patterns` warnings. (See\n https://gitlab.haskell.org/ghc/ghc/issues/16762#note_273343 for an\n example of this.) However, these warnings are actually a little\n _too_ precise, since implicitly bound type variables don't have\n exact binding sites like explicitly bound type variables do.\n A similar problem existed for\n \"`Different names for the same type variable`\" errors involving\n implicit tyvars bound by `bindHsQTyVars`.\n Therefore, we simply accept the less precise (but more accurate)\n source locations from `rnImplicitBndrs` in `rnFamInstEqn` and\n `bindHsQTyVars`. See\n `Note [Source locations for implicitly bound type variables]` in\n `GHC.Rename.HsType` for the full story.\n* In order for `rnImplicitBndrs` to work in `rnFamInstEqn`, it needs\n to be able to look up names from the parent class (in the event\n that we are renaming an associated type family instance). As a\n result, `rnImplicitBndrs` now takes an argument of type\n `Maybe assoc`, which is `Just` in the event that a type family\n instance is associated with a class.\n* Previously, GHC kept track of three type synonyms for free type\n variables in the renamer: `FreeKiTyVars`, `FreeKiTyVarsDups`\n (which are allowed to contain duplicates), and\n `FreeKiTyVarsNoDups` (which contain no duplicates). However, making\n is a distinction between `-Dups` and `-NoDups` is now pointless, as\n all code that returns `FreeKiTyVars{,Dups,NoDups}` will eventually\n end up being passed to `rnImplicitBndrs`, which removes duplicates.\n As a result, I decided to just get rid of `FreeKiTyVarsDups` and\n `FreeKiTyVarsNoDups`, leaving only `FreeKiTyVars`.\n* The `bindLRdrNames` and `deleteBys` functions are now dead code, so\n I took the liberty of removing them.\n\n",

As a consequence, this functions can\n be inlined, and trigger case-of-known constructor (_e.g._\n `kindRep_maybe`, `isLiftedRuntimeRep`, `isMultiplicityTy`,\n `getTyVar_maybe`, `splitAppTy_maybe`, `splitFunType_maybe`,\n `tyConAppTyCon_maybe`). The common pattern about all these functions\n is that they are almost always used as views, and immediately\n consumed by a case expression. This commit also mark them asx `INLINE`.\n- In `subst_ty` add a special case for nullary `TyConApp`, which avoid\n allocations altogether.\n- Use `mkTyConApp` in `subst_ty` for the general `TyConApp`.

Historically, this was\ndone with the `typeToLHsType` function, which walked over the entire\n`Type` and attempted to construct an `LHsType` with the same overall\nstructure. `typeToLHsType` is quite complicated, however, and has\nbeen the subject of numerous bugs over the years (e.g., #14579).\n\nLuckily, there is an easier way to accomplish the same thing: the\n`XHsType` constructor of `HsType`. `XHsType` bundles an `NHsCoreTy`,\nwhich allows embedding a Core `Type` directly into an `HsType`,\navoiding the need to laboriously convert from one to another (as\n`typeToLHsType` did). Moreover, renaming and typechecking an\n`XHsType` is simple, since one doesn't need to do anything to a\nCore `Type`...\n\n...well, almost. For the reasons described in\n`Note [Typechecking NHsCoreTys]` in `GHC.Tc.Gen.HsType`, we must\napply a substitution that we build from the local `tcl_env` type\nenvironment. But that's a relatively modest price to pay.\n\nNow that `GeneralizedNewtypeDeriving` uses `NHsCoreTy`, the\n`typeToLHsType` function no longer has any uses in GHC, so this patch\nrips it out. Some additional tweaks to `hsTypeNeedsParens` were\nnecessary to make the new `-ddump-deriv` output correctly\nparenthesized, but other than that, this patch is quite\nstraightforward.\n\nThis is a mostly internal refactoring, although it is likely that\n`GeneralizedNewtypeDeriving`-generated code will now need fewer\nlanguage extensions in certain situations than it did before.\n\n",

This can even lead to some strange interactions with\n`ScopedTypeVariables`, as demonstrated in #18240. This patch makes\nGHC more consistently reject instance types with nested\n`forall`s/contexts so as to prevent these strange interactions.\n\nOn the implementation side, this patch tweaks `splitLHsInstDeclTy`\nand `getLHsInstDeclHead` to not look through parentheses, which can\nbe semantically significant. I've added a\n`Note [No nested foralls or contexts in instance types]` in\n`GHC.Hs.Type` to explain why. This also introduces a\n`no_nested_foralls_contexts_err` function in `GHC.Rename.HsType` to\ncatch nested `forall`s/contexts in instance types. This function is\nnow used in `rnClsInstDecl` (for ordinary instance declarations) and\n`rnSrcDerivDecl` (for standalone `deriving` declarations), the latter\nof which fixes #18271.\n\nOn the documentation side, this adds a new\n\"Formal syntax for instance declaration types\" section to the GHC\nUser's Guide that presents a BNF-style grammar for what is and isn't\nallowed in instance types.\n\nFixes #18240.
