ghc-internal: avoid depending on GHC.Internal.Control.Monad.Fix
This module contains the definition of MonadFix, since we want an
instance for IO, that instance requires a lot of machinery and we want
to avoid an orphan instance, this will naturally be quite high up in the
dependency graph.
So we want to avoid other modules depending on it as far as possible.
On Windows, the IO manager depends on the RTSFlags type, which
transtively depends on MonadFix. We refactor things to avoid this
dependency, which would have caused a regression.

Refine the imports of `System.IO.OS`
Commit 68bd08055594b8cbf6148a72d108786deb6c12a1 replaced the
`GHC.Internal.Data.Bool` import by a `GHC.Internal.Base` import.
However, while the `GHC.Internal.Data.Bool` import was conditional and
partial, the `GHC.Internal.Base` import is unconditional and total. As a
result, the import list is not tuned to import only the necessary bits
anymore, and furthermore GHC emits a lot of warnings about redundant
imports.
This commit makes the `GHC.Internal.Base` import conditional and partial
in the same way that the `GHC.Internal.Data.Bool` import was.

wasm: add /assets endpoint to serve user-specified assets
This patch adds an `/assets` endpoint to the wasm dyld http server, so
that users can also fetch assets from the same host with sensible
default MIME types, without needing a separate http server for assets
that also introduces CORS headaches:
- A `-fghci-browser-assets-dir` driver flag is added to specify the
assets root directory (defaults to `$PWD`)
- The dyld http server fetches `mime-db` on demand and uses it as
source of truth for mime types.
Closes #26951.

Fix -fcheck-prim-bounds for non constant args (#26958)
Previously we were only checking bounds for constant (literal)
arguments!
I've refactored the code to simplify the generation of out-of-line Cmm
code for the primop composed of some inline code + some call to an
external Cmm function.

Notes added [Error Context Stack] [Typechecking by expansion: overview]
Notes updated Note [Expanding HsDo with XXExprGhcRn]
-------------------------
Metric Decrease:
T9020
-------------------------
* Streamlines implementations of `tcExpr` and `tcXExpr` to work on `XExpr`
* Kills `VACtxt` (and its associated `VAExpansion` and `VACall`) datatype, it is subsumed by simply a `SrcSpan`.
* Kills the function `addHeadCtxt` as it is now mearly setting a location
* The function `tcValArgs` does its own argument number management
* Makes `splitHsApps` not look through `XExpr`
* `tcExprSigma` is called if the head of the expression after calling `splitHsApps` turns out to be an `XExpr`
* Removes location information from `OrigPat` payload
* Removes special case of tcBody from `tcLambdaMatches`
* Removes special case of `dsExpr` for `ExpandedThingTc`
* Rename `HsThingRn` to `SrcCodeCtxt`
* Kills `tcl_in_gen_code` and `tcl_err_ctxt`. It is subsumed by `ErrCtxtStack`
* Kills `ExpectedFunTyOrig`. It is subsumed by `CtOrigin`
* Fixes `CtOrigin` for `HsProjection` case in `exprCtOrigin`. It was previously assigned to be `SectionOrigin`. It is now just the expression
* Adds a new `CtOrigin.ExpansionOrigin` for storing the original syntax
* Adds a new `CtOrigin.ExpectedTySyntax` as a replacement for `ExpectedTySyntaxOp`. Cannot kill the former yet because of `ApplicativeDo`
* Renames `tcMonoExpr` -> `tcMonoLExpr`, `tcMonoExprNC` -> `tcMonoLExpr`
* Renames `EValArg`, `EValArgQL` fields: `ea_ctxt` -> `ea_loc_span` and `eaql_ctx` -> `eaql_loc_span`
* kill `PopErrCtxt` from `XXExprGhcRn`
* simplify `addArgCtxt` and push `setSrcSpan` inside `addLExprCtxt`. Make sure addExprCtxt is not called by itself
* fun_orig in tcApp depends on the SrcSpan of the head of the application chain (similar to addArgCtxt)
* rename fun_ctxt to fun_lspan, fun_orig passed in tcInstFun to default to app chain head if its user located, fall back to srcCodeOrigin if it's a generated location
* fix quickLookArg function to blame the correct application chain head. The arguments application chain head should be blamed, not the original head when we quick look arg
* Make sure only expression wrapped around generated src span are ignored while adding them to the error context stack
* `getDeepSubsumptionFlag_DataConHead` performs a non-trivial traversal if the expression passed to it is complex.
This traversal is necessary if the head of the function is an `XExpr` and `splitHsApps` does not look through them
- The deepsubsumption flag is stored in EVAlArgQL to reduce the need to call `getDeepSubsumptionFlag_DataConHead`
- `getDeepSubsumptionFlag_DataConHead` is called in `tcExprSigma` and `tcInferAppHead` to reduce AST traversals
* Make a new variant `GeneratedSrcSpan` in `SrcSpan` for HIEAst Nodes
* wrap `fromListN` with a generated src span with GeneratedSrcSpanDetails field to store the original srcspan
* remove `UnhelpfulGenerated` from `UnhelpfulSpanReason` and into new datatype `GeneratedSrcSpanDetails`

Remove `extra_src_files` variable from `testsuite/driver/testlib.py`
While reading through the test harness code, I noticed this variable
with a TODO attached that referenced #12223. Although that bug is
closed, it strongly implied that this special-case variable that only
affected a single test was expected to be removed at some point.
I also looked at 3415bcaa0b1903b5e12dfaadb5b774718e406eab---where it
was added---whose commit message suggested that it would have been
desirable to remove it, but that there were special circumstances that
meant it had to remain (though it doesn't elucidate what those special
circumstances are).
However, the special circumstances were mentioned as if the test was
in a different location than is currently is, so I decided to try
changing the test to use the standard `extra_files` mechanism, which
works in local testing.
This also seems like a reasonable time to remove the script that was
originally used in the transition, since it doesn't really serve a
purpose anymore.

determinism: Use a stable sort in WithHsDocIdentifiers binary instance
`WithHsDocIdentifiers` is defined as
```
71 data WithHsDocIdentifiers a pass = WithHsDocIdentifiers
72 { hsDocString :: !a
73 , hsDocIdentifiers :: ![Located (IdP pass)]
74 }
```
This list of names is populated from `rnHsDocIdentifiers`, which calls
`lookupGRE`, which calls `lookupOccEnv_AllNameSpaces`, which calls
`nonDetEltsUFM` and returns the results in an order depending on
uniques.
Sorting the list with a stable sort before returning the interface makes
the output deterministic and follows the approach taken by other fields
in `Docs`.

rts: Switch prim to use modern atomic compiler builtins
The __sync_*() atomic compiler builtins have been deprecated in GCC
for a while now and also don't provide variants for 64-bit values
such as __sync_fetch_and_add_8().
Thus, replace them with the modern __atomic_*() compiler builtins and
while we're at it, also drop the helper macro CAS_NAND() which is now
no longer needed since we stopped using the __sync_*() compiler builtins
altogether.

ghc-toolchain: add C11 check
This patch partially reverts commit
b8307eab80c5809df5405d76c822bf86877f5960 that removed C99 check in
autoconf/ghc-toolchain. Now we:
- No longer re-implement `FP_SET_CFLAGS_C11` similar to
`FP_SET_CFLAGS_C99` in the past, since autoconf doesn't provide a
convenient `AC_PROG_CC_C11` function. ghc-toolchain will handle it
anyway.
- The Cmm CPP C99 check is relanded and repurposed for C11.
- The C99 logic in ghc-toolchain is relanded and repurposed for C11.
- The C99 check in Stg.h is corrected to check for C11. The obsolete
_ISOC99_SOURCE trick is dropped.
- Usages of `-std=gnu99` in the testsuite are corrected to use
`-std=gnu11`.
Closes #26908.

Simplify the treatment of static forms
This MR implements GHC proposal 732: simplify static forms,
https://github.com/ghc-proposals/ghc-proposals/pull/732
thereby addressing #26556.
See `Note [Grand plan for static forms]` in GHC.Iface.Tidy.StaticPtrTable
The main changes are:
* There is a new, simple rule for (static e), namely that the free
term variables of `e` must be bound at top level. The check is
done in the `HsStatic` case of `GHC.Rename.Expr.rnExpr`
* That in turn substantially simplifies the info that the typechecker
carries around in its type environment. Hooray.
* The desugarer emits static bindings to top level directly; see the
`HsStatic` case of `dsExpr`.
* There is no longer any special static-related magic in the FloatOut
pass. And the main Simplifier pipeline no longer needs a special case
to run FloatOut even with -O0. Hooray.
All this forced an unexpected change to the pattern match checker. It
recursively invokes the main Hs desugarer when it wants to take a look
at a term to spot some special cases (notably constructor applications).
We don't want to emit any nested (static e) bindings to top level a
second time! Yikes.
That forced a modest refactor in GHC.HsToCore.Pmc:
* The `dsl_nablas` field of `DsLclEnv` now has a `NoPmc` case, which says
"I'm desugaring just for pattern-match checking purposes".
* When that flag is set we don't emit static binds.
That in turn forces a cascade of refactoring, but the net effect is an
improvement; less risk of duplicated (even exponential?) work.
See Note [Desugaring HsExpr during pattern-match checking].

ghc-internal: avoid depending on GHC.Internal.Exts
This module is mostly just re-exports. It made sense as a user-facing
module, but there's no good reason ghc-internal modules should depend on
it and doing so linearises the module graph
- move considerAccessible to GHC.Internal.Magic
Previously it lived in GHC.Internal.Exts, but it really deserves to live
along with the other magic function, which are already re-exported from .Exts
- move maxTupleSize to GHC.Internal.Tuple
This previously lived in GHC.Internal.Exts but a comment already said it
should be moved to .Tuple

Hide implementation details from base exception stack traces
Ensure we hide the implementation details of the exception throwing mechanisms:
* `undefined`
* `throwSTM`
* `throw`
* `throwIO`
* `error`
The `HasCallStackBacktrace` should always have a length of exactly 1,
not showing internal implementation details in the stack trace, as these
are vastly distracting to end users.

Fix linking against libm by moving the -lm option
For those systems that need -lm for getting math functions, this is
currently added on the link line very early, before the object files being
linked together. Newer toolchains enable --as-needed by default, which means
-lm is ignored at that point because no object requires a math function
yet. With such toolchains, we thus have to add -lm after the objects, so the
linker actually includes libm in the link.

Add optional `SrcLoc` to `StackAnnotation` class
`StackAnnotation`s give access to an optional `SrcLoc` field that
user-added stack annotations can use to provide better backtraces in both error
messages and when decoding the callstack.
We update builtin stack annotations such as `StringAnnotation` and
`ShowAnnotation` to also capture the `SrcLoc` of the current `CallStack`
to improve backtraces by default (if stack annotations are used).
This change is backwards compatible with GHC 9.14.1.

Notes updated Note [Expanding HsDo with XXExprGhcRn]
-------------------------
Metric Decrease:
T9020
-------------------------
* Streamlines implementations of `tcExpr` and `tcXExpr` to work on `XExpr`
* Kills `VACtxt` (and its associated `VAExpansion` and `VACall`) datatype, it is subsumed by simply a `SrcSpan`.
* Kills the function `addHeadCtxt` as it is now mearly setting a location
* The function `tcValArgs` does its own argument number management
* Makes `splitHsApps` not look through `XExpr`
* `tcExprSigma` is called if the head of the expression after calling `splitHsApps` turns out to be an `XExpr`
* Removes location information from `OrigPat` payload
* Removes special case of tcBody from `tcLambdaMatches`
* Removes special case of `dsExpr` for `ExpandedThingTc`
* Rename `HsThingRn` to `SrcCodeCtxt`
* Kills `tcl_in_gen_code` and `tcl_err_ctxt`. It is subsumed by `ErrCtxtStack`
* Kills `ExpectedFunTyOrig`. It is subsumed by `CtOrigin`
* Fixes `CtOrigin` for `HsProjection` case in `exprCtOrigin`. It was previously assigned to be `SectionOrigin`. It is now just the expression
* Adds a new `CtOrigin.ExpansionOrigin` for storing the original syntax
* Adds a new `CtOrigin.ExpectedTySyntax` as a replacement for `ExpectedTySyntaxOp`. Cannot kill the former yet because of `ApplicativeDo`
* Renames `tcMonoExpr` -> `tcMonoLExpr`, `tcMonoExprNC` -> `tcMonoLExpr`
* Renames `EValArg`, `EValArgQL` fields: `ea_ctxt` -> `ea_loc_span` and `eaql_ctx` -> `eaql_loc_span`
* kill `PopErrCtxt` from `XXExprGhcRn`
* simplify `addArgCtxt` and push `setSrcSpan` inside `addLExprCtxt`. Make sure addExprCtxt is not called by itself
* fun_orig in tcApp depends on the SrcSpan of the head of the application chain (similar to addArgCtxt)
* rename fun_ctxt to fun_lspan, fun_orig passed in tcInstFun to default to app chain head if its user located, fall back to srcCodeOrigin if it's a generated location
* fix quickLookArg function to blame the correct application chain head. The arguments application chain head should be blamed, not the original head when we quick look arg
* Make sure only expression wrapped around generated src span are ignored while adding them to the error context stack
* `getDeepSubsumptionFlag_DataConHead` performs a non-trivial traversal if the expression passed to it is complex.
This traversal is necessary if the head of the function is an `XExpr` and `splitHsApps` does not look through them
- The deepsubsumption flag is stored in EVAlArgQL to reduce the need to call `getDeepSubsumptionFlag_DataConHead`
- `getDeepSubsumptionFlag_DataConHead` is called in `tcExprSigma` and `tcInferAppHead` to reduce AST traversals
* Make a new variant `GeneratedSrcSpan` in `SrcSpan` for HIEAst Nodes
* wrap `fromListN` with a generated src span with GeneratedSrcSpanDetails field to store the original srcspan
* remove `UnhelpfulGenerated` from `UnhelpfulSpanReason` and into new datatype `GeneratedSrcSpanDetails`

Remove in-package dependencies on `GHC.Internal.System.IO`
This contribution eliminates all dependencies on
`GHC.Internal.System.IO` from within `ghc-internal`. It comprises the
following changes:
* Make `GHC.Internal.Fingerprint` independent of I/O support
* Tighten the dependencies of `GHC.Internal.Data.Version`
* Move some `IsString` instance declarations into `base`
* Move the `* -> *` `Heap.Closure` instances into `ghc-heap`
* Move some code that needs `System.IO` to `template-haskell`
* Tighten the dependencies of `GHC.Internal.TH.Monad`
* Move the `GHC.ResponseFile` implementation into `base`
* Move the `System.Exit` implementation into `base`
* Move the `GHCi.Helpers` implementation into `base`
* Move the `System.IO.OS` implementation into `base`

Fix -fcheck-prim-bounds for non constant args (#26958)
Previously we were only checking bounds for constant (literal)
arguments!
I've refactored the code to simplify the generation of out-of-line Cmm
code for the primop composed of some inline code + some call to an
external Cmm function.

Check for negative type literals in the type checker (#26861)
GHC disallows negative type literals (e.g., -1), as tested by T8306 and
T8412. This check is currently performed in the renamer:
rnHsTyLit tyLit@(HsNumTy x i) = do
when (i < 0) $
addErr $ TcRnNegativeNumTypeLiteral tyLit
However, this check can be bypassed using RequiredTypeArguments
(see the new test case T26861). Prior to this patch, such programs
caused the compiler to hang instead of reporting a proper error.
This patch addresses the issue by adding an equivalent check in
the type checker, namely in tcHsType.
The diff is deliberately minimal to facilitate backporting. A more
comprehensive rework of HsTyLit is planned for a separate commit.

Consistent pretty-printing of HsString, HsIsString, HsStrTy
Factor out a helper to pretty-print string literals, thus fixing newline
handling for overloaded string literals and type literals.
Test cases: T26860ppr T26860ppr_overloaded T26860ppr_tylit
