Problem: in 02279a9c the type-level [] syntax was changed from a built-in name
to an alias for the GHC.Types.List constructor. badOrigBinding assumes that if
a name is not built-in then it must have come from TH quotation, but this is
not necessarily the case with [].
The outdated assumption in badOrigBinding leads to incorrect error messages.
This code:
data []
Fails with "Cannot redefine a Name retrieved by a Template Haskell quote: []"
Unfortunately, there is not enough information in RdrName to directly determine
if the name was constructed via TH or by the parser, so this patch changes the
error message instead.
It unifies TcRnIllegalBindingOfBuiltIn and TcRnNameByTemplateHaskellQuote
into a new error TcRnBindingOfExistingName and changes its wording to avoid
guessing the origin of the name.

This reverts commit d0d7ba0fb053ebe7f919a5932066fbc776301ccd.
The module now lacks a dependency on GHC.Num.BigNat which it implicitly
depends on. It is causing all CI jobs to fail so we revert without haste
whilst the patch can be fixed.

This fixes the fact that we were not reporting orphan family instances
at all. The fix here is easy, but touches a bit of code. I refactored
the code to be much more similar to the way that class instances are done:
- Add a fi_orphan field to FamInst, like the is_orphan field in ClsInst
- Make newFamInst initialise this field, just like newClsInst
- And make newFamInst report a warning for an orphan, just like newClsInst
- I moved newFamInst from GHC.Tc.Instance.Family to GHC.Tc.Utils.Instantiate,
just like newClsInst.
- I added mkLocalFamInst to FamInstEnv, just like mkLocalClsInst in InstEnv
- TcRnOrphanInstance and SuggestFixOrphanInstance are now parametrised
over class instances vs type/data family instances.

Previously UnliftedTVar2 would fail when run with multiple capabilities
(and possibly even with one capability) as it would assume that
`killThread#` would immediately kill the "increment" thread.
Also, refactor the the executable to now succeed with no output and
fails with an exit code.

Previously, when using `capi` calling convention in foreign declarations,
code generator failed to handle const-cualified pointer return types.
This resulted in CC toolchain throwing `-Wincompatible-pointer-types-discards-qualifiers`
warning.
`Foreign.C.Types.ConstPtr` newtype was introduced to handle these cases -
special treatment was put in place to generate appropritetly qualified C
wrapper that no longer triggers the above mentioned warning.

Asm-shortcutting may produce relative references to symbols defined in
other compilation units. This is not something that MachO relocations
support (see #21972). For this reason we disable the optimisation on
Darwin. We do so without a warning since this flag is enabled by `-O2`.
Another way to address this issue would be to rather implement a
PLT-relocatable jump-table strategy. However, this would only benefit
Darwin and does not seem worth the effort.
Closes #21972.

Previously we tried to lower the alignment requirement as far as
possible, based on the section kind inferred from the CLabel. For info
tables, .p2align 1 was applied given the GC should only need the
lowest bit to tag forwarding pointers. But this would lead to
unaligned loads/stores, which has a performance penalty even if the
wasm spec permits it. Furthermore, the test suite has shown memory
corruption in a few cases when compacting gc is used.
This patch takes a more conservative approach: all data sections
except C strings align to word size.

We use keepCAFsForGHCi.c to force -fkeep-cafs behaviour by using a
__attribute__((constructor)) function.
This broke for static builds where the linker discarded the object file
since it was not reverenced from any exported code. We fix this by
asserting that the flag is enabled using a function in the same module
as the constructor. Which causes the object file to be retained by the
linker, which in turn causes the constructor the be run in static builds.
This changes nothing for dynamic builds using the ghc library. But causes
static to also retain CAFs (as we expect them to).
Fixes #22417.

Unlike most other data constructors, data constructors declared with `type data`
are represented in `TyThing`s as `ATyCon` rather than `ADataCon`. The `ATyCon`
case in `tyThingParent_maybe` previously did not consider the possibility of
the underlying `TyCon` being a promoted data constructor, which led to the
oddities observed in #22817. This patch adds a dedicated special case in
`tyThingParent_maybe`'s `ATyCon` case for `type data` data constructors to fix
these oddities.
Fixes #22817.

This patch fixes two issues in the way that `type data` declarations were
reified with Template Haskell:
* `type data` data constructors are now properly reified using `DataConI`.
This is accomplished with a special case in `reifyTyCon`. Fixes #22818.
* `type data` type constructors are now reified in `reifyTyCon` using
`TypeDataD` instead of `DataD`. Fixes #22819.

The key change is that in GHC.Core.Opt.Specialise.specLookupRule
we were using realIdUnfolding, which ignores the loop-breaker
flag. When given a loop breaker, rule matching therefore
looped infinitely -- #22802.
In fixing this I refactored a bit.
* Define GHC.Core.InScopeEnv as a data type, and use it.
(Previously it was a pair: hard to grep for.)
* Put several functions returning an IdUnfoldingFun into
GHC.Types.Id, namely
idUnfolding
alwaysActiveUnfoldingFun,
whenActiveUnfoldingFun,
noUnfoldingFun
and use them. (The are all loop-breaker aware.)

This commit updates the user's guide section on overlapping instance candidate
elimination to use "or" verbiage instead of "either/or" in regards to the
current pair of candidates' being overlappable or overlapping. "Either IX is
overlappable, or IY is overlapping" can cause confusion as it suggests "Either
IX is overlappable, or IY is overlapping, but not both".

This patch fixes #22745 and #15205, which are about GHC's
failure to discard unnecessary superclass selections that
yield coercions. See
GHC.Core.Utils Note [exprOkForSpeculation and type classes]
The main changes are:
* Write new Note [NON-BOTTOM_DICTS invariant] in GHC.Core, and
refer to it
* Define new function isTerminatingType, to identify those
guaranteed-terminating dictionary types.
* exprOkForSpeculation has a new (very simple) case for ClassOpId
* ClassOpId has a new field that says if the return type is
an unlifted type, or a terminating type.
This was surprisingly tricky to get right. In particular note
that unlifted types are not terminating types; you can write an
expression of unlifted type, that diverges. Not so for dictionaries
(or, more precisely, for the dictionaries that GHC constructs).

Currently, the wasm NCG has an implicit assumption: all CmmSwitch
scrutinees are 32-bit integers. This is not always true; #22864 is one
counter-example with a 64-bit scrutinee. This patch fixes the logic by
explicitly converting the scrutinee to a word that can be used as a
br_table operand. Fixes #22871. Also includes a regression test.

LLVM 15 turns on the new pass manager by default, which we have yet to
migrate to so for new we pass the `-enable-new-pm-0` flag in our
llvm-passes flag.
LLVM 11 was the first version to support the `-enable-new-pm` flag so we
bump the lowest supported version to 11.
Our CI jobs are using LLVM 12 so they should continue to work despite
this bump to the lower bound.

This MR runs the testsuite for the JS backend. Note that this is a
temporary solution until !9515 is merged.
Key point: The CI runs hadrian on the built cross compiler _but not_ on
the bindist.
Other Highlights:
- stm submodule gets a bump to mark tests as broken
- several tests are marked as broken or are fixed by adding more
- conditions to their test runner instance.
List of working commit messages:
CI: test cross target _and_ emulator
CI: JS: Try run testsuite with hadrian
JS.CI: cleanup and simplify hadrian invocation
use single bracket, print info
JS CI: remove call to test_compiler from hadrian
don't build haddock
JS: mark more tests as broken
Tracked in https://gitlab.haskell.org/ghc/ghc/-/issues/22576
JS testsuite: don't skip sum_mod test
Its expected to fail, yet we skipped it which automatically makes it
succeed leading to an unexpected success,
JS testsuite: don't mark T12035j as skip
leads to an unexpected pass
JS testsuite: remove broken on T14075
leads to unexpected pass
JS testsuite: mark more tests as broken
JS testsuite: mark T11760 in base as broken
JS testsuite: mark ManyUnbSums broken
submodules: bump process and hpc for JS tests
Both submodules has needed tests skipped or marked broken for th JS
backend. This commit now adds these changes to GHC.

Ticket #22807 pointed out that the RHS sharing was not compatible with
-fignore-interface-pragmas because the flag would remove unfoldings from
identifiers before the `extra-decls` field was populated.
For the 9.6 timescale the only solution is to disable this sharing,
which will make interface files bigger but this is acceptable for the
first release of `-fwrite-if-simplified-core`.
For 9.8 it would be good to fix this by implementing #20056 due to the
large number of other bugs that would fix.
I also improved the error message in tc_iface_binding to avoid the "no match
in record selector" error but it should never happen now as the entire
sharing logic is disabled.
Also added the currently broken test for #22807 which could be fixed by
!6080
Fixes #22807

The clang based toolchain uses ucrt as its math library

will cause incompatibilities as the default routines in both

This may be due to you not asking GHCi to load extra object files,
archives or DLLs needed by your current session. Restart GHCi, specifying
the missing library using the -L/path/to/object/dir and -lmissinglibname
flags, or simply by naming the relevant files on the GHCi command line.

This commit fixes the BFD style import library support in the runtime
linker. This was accidentally broken during the refactoring to clang
and went unnoticed because clang itself is unable to generate the BFD
style import libraries.
With this change we can not link against both GCC or Clang produced
libraries again and intermix code produced by both compilers.

Despite Cabal supporting any architecture name, `cabal --check` only
supports a few built-in ones. Sadly `cabal --check` is used by Hackage
hence using any non built-in name in a package (e.g. `arch(js)`) is
rejected and the package is prevented from being uploaded on Hackage.
Luckily built-in support for the `javascript` architecture was added for
GHCJS a while ago. In order to allow newer `base` to be uploaded on
Hackage we make the switch from `js` to `javascript` architecture.
Fixes #22740.

This fixes an interaction between aging and weak pointer handling which

While in the area, we also significantly improve the assertions
regarding weak pointers.

The current segments are conceptually owned by the mutator, not the
collector. Consequently, it was quite tricky to prove that the mutator
would not race with the collect due to this shared state. It turns out
that such races are possible: when resizing the current segment array
we may concurrently try to take a heap census. This will attempt to walk
the current segment array, causing a data race.
Fix this by moving the current segment array into `Capability`, where it
belongs.
Fixes #22926.

The nonmoving collector does not use `oldest_gen->blocks` to track its
block list. However, it nevertheless updates `oldest_gen->n_blocks` to
ensure that its size is accounted for by the storage manager.
Consequently, we must not attempt to assert consistency between the two.
