The main purpose of this is to tuck the module name `xxx` in `module xxx where` into the hieAst. It should fix #24493. The following have been done: 1. Renamed and update the `tcg_doc_hdr :: Maybe (LHsDoc GhcRn)` to `tcg_hdr_info :: (Maybe (LHsDoc GhcRn), Maybe (XRec GhcRn ModuleName))` To store the located module name information. 2. update the `RenamedSource` and `RenamedStuff` with extra `Maybe (XRec GhcRn ModuleName)` located module name information. 3. add test `testsuite/tests/hiefile/should_compile/T24493.hs` to ensure the module name is added and update several relevent tests. 4. accompanied submodule haddoc test update MR in haddock!53

As noted by #24344, `strerror` is not necessarily thread-safe. Thankfully, POSIX.1-2001 has long offered `strerror_r`, which is safe to use. Fixes #24344. CLC discussion: https://github.com/haskell/core-libraries-committee/issues/249

This fixes a regression in retainer set profiling introduced by b0293f78. Prior to that commit the heap traversal word would be initialized by `SET_HDR` using `LDV_RECORD_CREATE`. However, the commit added a `doingLDVProfiling` check in `LDV_RECORD_CREATE`, meaning that this initialization no longer happened. Given that this initialization was awkwardly indirectly anyways, I have fixed this by explicitly initializating the heap traversal word to `NULL` in `SET_PROF_HDR`. This is equivalent to the previous behavior, but much more direct. Fixes #24513.

This was simply reexporting things from `ghc-prim`. Instead reexport these directly from `Data.Kind`. Also add build ordering dependency to work around #23942.

Also tweak rendering of SrcSpan to remove extra blank line.

Most GhcExceptions are user-facing errors and therefore the ExceptionContext has little value. Ideally we would enable it in the DEBUG compiler but I am leaving this for future work.

Here we introduce the `Backtraces` type and associated machinery for attaching these via `ExceptionContext`. These has a few compile-time regressions (`T15703` and `T9872d`) due to the additional dependencies in the exception machinery. As well, there is a surprisingly large regression in the `size_hello_artifact` test. This appears to be due to various `Integer` and `Read` bits now being reachable at link-time. I believe it should be possible to avoid this but I have accepted the change for now to get the feature merged.

Vladislav Zavialov authored* Main change: make the error message generated by mkFunTysMsg more accurate by changing "value arguments" to "visible arguments". * Refactor: define a new type synonym VisArity and use it instead of Arity in a few places. It might be the case that there other places in the compiler that should talk about visible arguments rather than value arguments, but I haven't tried to find them all, focusing only on the error message reported in the ticket.

These were changes are all triggered by #24471. 1. Make GHC.Core.Opt.SetLevels.lvlMFE behave better when there are many free variables. See Note [Large free-variable sets]. 2. Make GHC.Core.Opt.Arity.floatIn a bit lazier in its Cost argument. This benefits the common case where the ArityType turns out to be nullary. See Note [Care with nested expressions] 3. Make GHC.CoreToStg.Prep.cpeArg behave for deeply-nested expressions. See Note [Eta expansion of arguments in CorePrep] wrinkle (EA2). Compile times go down by up to 4.5%, and much more in artificial cases. (Geo mean of compiler/perf changes is -0.4%.) Metric Decrease: CoOpt_Read T10421 T12425 -
This is a temporary measure to improve CI reliability until a proper solution is developed. Works around #23942.

This commit adds an assertion to Bdescr() to assert the pointer is indeed heap allocated. This is useful to rule out RTS bugs that attempt to access non-existent block descriptor of a static closure, #24492 being one such example.
-
This commit exposes HeapAlloc.h as a public header. The intention is to expose HEAP_ALLOCED/HEAP_ALLOCED_GC, so they can be used in assertions in other public headers, and they may also be useful for user code.

This patch adds a -xr RTS option to control the size of virtual memory address space reserved by the two step allocator on a 64-bit platform, see added documentation for explanation. Closes #24498.

There were a few issues with the hackage links: 1. We were using the package id rather than the package name for the package links. This is fixed by now allowing the template to mention %pkg% or %pkgid% and substituing both appropiatly. 2. The `--haddock-base-url` flag is renamed to `--haddock-for-hackage` as the new base link works on a local or remote hackage server. 3. The "src" path including too much stuff, so cross-package source links were broken as the template was getting double expanded. Fixes #24086

The file mentioned some artifacts relating to the base library. I have renamed these to the new ghc-internal variants.

This adds the upload of ghc-internal and ghc-experimental to our scripts which upload packages to hackage.

Fix a bug in the x86 ncg where results would be wrong when the desired output register and one of the input registers were the same global. Also adds a tiny optimization to make use of the memory addressing support when convenient. Fixes #24496

cmmToRawCmmHook was added 4 years ago in d561c8f6. Its only user is the Asterius project, which has been archived and deprecated in favor of the ghc wasm backend. This patch starts deprecating cmmToRawCmmHook by placing a DEPRECATED pragma, and actual removal shall happen in a future GHC major release if no issue to oppose the deprecation has been raised in the meantime.

This enriched the `CtOrigin` for non-linear patterns to include data of the pattern that created the constraint (which can be quite useful if it occurs nested in a pattern) as well as an explanation why the pattern is non-restricted in (at least in some cases).

This implements Proposal 0475, introducing the `ListTuplePuns` extension which is enabled by default. Disabling this extension makes it invalid to refer to list, tuple and sum type constructors by using built-in syntax like `[Int]`, `(Int, Int)`, `(# Int#, Int# #)` or `(# Int | Int #)`. Instead, this syntax exclusively denotes data constructors for use with `DataKinds`. The conventional way of referring to these data constructors by prefixing them with a single quote (`'(Int, Int)`) is now a parser error. Tuple declarations have been moved to `GHC.Tuple.Prim` and the `Solo` data constructor has been renamed to `MkSolo` (in a previous commit). Unboxed tuples and sums now have real source declarations in `GHC.Types`. Unit and solo types for tuples are now called `Unit`, `Unit#`, `Solo` and `Solo#`. Constraint tuples now have the unambiguous type constructors `CTuple<n>` as well as `CUnit` and `CSolo`, defined in `GHC.Classes` like before. A new parser construct has been added for the unboxed sum data constructor declarations. The type families `Tuple`, `Sum#` etc. that were intended to provide nicer syntax have been omitted from this change set due to inference problems, to be implemented at a later time. See the MR discussion for more info. Updates the submodule utils/haddock. Updates the cabal submodule due to new language extension.
