This is necessary for prereleases, where GHCup accesses the release via
`$ver/`

To do so is unsafe as we have no way of identifying references to
symbols provided by the object.

Fixes #24513. Fixes #23993.

The heap census may contain references (e.g. `Counter.identity`) to
static data which must be available when the census is reported at the
end of execution.

Fixes #24512.

Bumps haddock submodule.

The old `combine` approach was quite fragile due to use of filename
globbing. Moreover, it didn't parallelize well. This refactoring
makes the goal more obvious, parallelizes better, and is more robust.

This was previously mistakenly added to the GHC 9.8 release notes.

It appears that this was

This provides PVP compliance while maintaining a clear correspondence
between GHC releases and `ghc-internal` versions.

1 MByte was just too tight and failed intermittently on some platforms
(e.g. CentOS 7). Bumping the limit to 8 MByte should provide sufficient
headroom.

Fixes #23139.

In particular this fails on platforms without `dlinfo`. I plan to
address this but not before 9.10.1-alpha1.

I will fix this but not in time for 9.10.1-alpha1

* Mention TypeAbstractions in 9.10.1-notes.rst
* Set the status to "Experimental".
* Add a "Since: GHC 9.x" comment to each section.

Don't allocate a Ptr constructor per frame.

Here we add the unit ID to the info table provenance structure.

This allows us to shave a 64-bit word off of the packed IPE entry size.

Previously we would eagerly allocate `InfoTableEnt`s for each
info table registered in the info table provenance map. However, this
costs considerable memory and initialization time. Instead we now
lazily decode these tables. This allows us to use one-third the memory
*and* opens the door to taking advantage of sharing opportunities within
a module.

This required considerable reworking since lookupIPE now must be passed
its result buffer.

Such that we can add new helpers into GHC.InfoProv.Types without
breakage.

This should have been done in 0f0c53a5 but I missed it.

There is nothing platform-dependent about our GOT implementation and
GOT support is needed by `T24171` on i386.

This replicates the behavior on Windows, where `Hi.exe` will produce
profiling output named `Hi.prof` instead of `Hi.exe.prof`.

While in the area I also fixed the extension-stripping logic, which
incorrectly rewrote `Hi.exefoo` to `Hi.foo`.

Closes #24515.

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 ghc/haddock!53

This patch improves the error messages from invalid type signatures by
trying to guess what the user did and suggesting an appropriate fix.

Partially fixes: #17879

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.

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.
