Add support for building bytecode libraries
A bytecode library is a collection of bytecode files (.gbc) and a
library which combines together additional object files.
A bytecode library is created by invoking GHC with the `-bytecodelib`
flag.
A library can be created from in-memory `ModuleByteCode` linkables or
by passing `.gbc` files as arguments on the command line.
Fixes #26298

Load bytecode libraries to satisfy package dependencies
This commit allows you to use a bytecode library to satisfy a package
dependency when using the interpreter.
If a user enables `-fprefer-byte-code`, then if a package provides a
bytecode library, that will be loaded and used to satisfy the
dependency.
The main change is to separate the relevant parts of the `LoaderState`
into external and home package byte code. Bytecode is loaded into either
the home package or external part (similar to HPT/EPS split), HPT
bytecode can be unloaded. External bytecode is never unloaded.
The unload function has also only been called with an empty list of
"stable linkables" for a long time. It has been modified to directly
implement a complete unloading of the home package bytecode linkables.
At the moment, the bytecode libraries are found in the "library-dirs"
field from the package description. In the future when `Cabal`
implements support for "bytecode-library-dirs" field, we can read the
bytecode libraries from there. No changes to the Cabal submodule are
necessary at the moment.
Four new tests are added in testsuite/tests/cabal, which generate fake
package descriptions and test loading the libraries into GHCi.
Fixes #26298

- don't pass the same value twice to functions
- some explanations of interesting but undocumented code paths
- adjust comment to not mention non-existent error message

driver: don't expect nodes to exist when checking paths between them
In `mgQueryZero`, previously node lookups were expected to never fail,
i.e. it was expected that when calculating the path between two nodes in
a zero level import graph, both nodes would always exist. This is not
the case, e.g. in some situations involving exact names (see the
test-case). The fix is to first check whether the node is present in the
graph at all, instead of panicking, just to report that there is no
path.
Closes #26568

hadrian: Use a response file to invoke GHC for dep gathering.
In some cases we construct an argument list too long for GHC to
handle directly on windows. This happens when we generate
the dependency file because the command line will contain
references to a large number of .hs files.
To avoid this we now invoke GHC using a response file when
generating dependencies to sidestep length limitations.
Note that we only pass the actual file names in the dependency
file. Why? Because this side-steps #26560

rts: Fix object file format detection in loadArchive
Commit 76d1041dfa4b96108cfdd22b07f2b3feb424dcbe seems to
have introduced this bug, ultimately leading to failure of
test T11788. I can only theorize that this test isn't run
in upstream's CI, because they don't build a static GHC.
The culprit is that we go through the thin archive, trying
to follow the members on the filesystem, but don't
re-identify the new object format of the member. This pins
`object_fmt` to `NotObject` from the thin archive.
Thanks to @angerman for spotting this.

Stack.Decode: Don't error on bitmap size 0
A RET_BCO may have a bitmap with no payload.
In that case, the bitmap = 0.
One can observe this by using -ddump-bcos and interpreting
```
main = pure ()
```
Observe, for instance, that the BCO for this main function has size 0:
```
ProtoBCO Main.main#0:
\u []
break<main:Main,0>() GHC.Internal.Base.pure
GHC.Internal.Base.$fApplicativeIO GHC.Internal.Tuple.()
bitmap: 0 []
BRK_FUN <breakarray> main:Main 0 <cc>
PACK () 0
PUSH_G GHC.Internal.Base.$fApplicativeIO
PUSH_APPLY_PP
PUSH_G GHC.Internal.Base.pure
ENTER
```
Perhaps we never tried to decode a stack in which a BCO like this was
present. However, for the debugger, we want to decode stacks of threads
stopped at breakpoints, and these kind of BCOs do get on a stack under
e.g. `stg_apply_interp_info` frames.
See the accompanying test in the next commit for an example to trigger
the bug this commit fixes.

hadrian: add with_profiled_libs flavour transformer
This patch adds a `with_profiled_libs` flavour transformer to hadrian
which is the exact opposite of `no_profiled_libs`. It adds profiling
ways to stage1+ rts/library ways, and doesn't alter other flavour
settings. It is useful when needing to test profiling logic locally
with a quick flavour.

rts: fix unaligned ReadSpB in interpretBCO
This commit fixes unaligned ReadSpB in interpretBCO, caught by UBSan:
```
+rts/Interpreter.c:2174:64: runtime load of misaligned address 0x004202059dd1 for type 'StgWord', which requires 8 byte alignment
```
To perform proper unaligned read, we define StgUnalignedWord as a type
alias of StgWord with aligned(1) attribute, and load StgUnalignedWord
instead of StgWord in ReadSpB, so the C compiler is aware that we're
not loading with natural alignment.

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+interpretBCO implements Cmm arithmetic primops by loading operands
+from the stack as C integers, applying C arithmetic operation, then
+storing the result back to the stack. But there are subtle differences
+in Cmm and C arithmetic operations:
+
+- The Cmm type system only tracks operand sizes for integer types, and
+ doesn't track signedness (#20652)
+- Cmm arithmetic operations are allowed to overflow based on two's
+ complement wrap-around semantics
+
+Meanwhile in C:
+
+- The C type system tracks signedness
+- Signed overflow is undefined behavior
+- Subword operands are implicitly promoted to int
+
+Consider an example where we do an `MO_Mul W16` on both 0xFFFF.
+Previously we would load each operand as a word, cast to a subword and
+do the multiplication. But C actually does multiplication on int,
+which is 32-bit on most platforms, and now a signed overflow occurs!
+
+To perform Cmm arithmetic without tripping on C undefined behavior, we
+now:
+
+- Always specify unsigned C operand type for the Cmm primop, unless
+ signed operand is absolutely needed for correctness (e.g. signed
+ comparison or right shift)
+- Explicitly promote operands to a C type no smaller than a host word,
+ so either StgInt or StgWord, depending on the signedness of ty,
+ hence the TYPE_IS_SIGNED macro

Add support for generating bytecode objects
This commit adds the `-fwrite-byte-code` option which makes GHC emit a
`.gbc` file which contains a serialised representation of bytecode.
The bytecode can be loaded by the compiler to avoid having to
reinterpret a module when using the bytecode interpreter (for example,
in GHCi).
There are also the new options:
* -gbcdir=<DIR>: Specify the directory to place the gbc files
* -gbcsuf=<suffix>: Specify the suffix for gbc files
The option `-fbyte-code-and-object-code` now implies
`-fwrite-byte-code`.
These performance tests fail due to https://github.com/haskell/directory/issues/204

Revert "Add a perf test for #26425"
This test has a large memory spike currently, which makes the test
sensitive, since if you allocate a little more or less, the precise
location where GC happens shifts and you observe a different part of the
spike.
Andreas told me to revert the patch for now, and he will add it back
when he fixes the memory spike.
This reverts commit 41bdb16fd083110a06507248f648c507a2feb4af.

testsuite: fix T3586 for non-SSE3 platforms
`T3586.hs` contains `-fvia-C -optc-msse3` which I think is a
best-effort basis to harvest the C compiler's auto vectorization
optimizations via the C backend back when the test was added. The
`-fvia-C` part is now a deprecated no-op because GHC can't fall back
to the C backend on a non-unregisterised build, and `-optc-msse3`
might actually cause the test to fail on non x86/x64 platforms, e.g.
recent builds of wasi-sdk would report `wasm32-wasi-clang: error:
unsupported option '-msse3' for target 'wasm32-unknown-wasi'`.
So this patch cleans up this historical cruft. `-fvia-C` is removed,
and `-optc-msse3` is only passed when cpuid contains `pni` (which
indicates support of SSE3).

Allow per constructor refinement of distinct-constructor-tables
Introduce `-fno-distinct-constructor-tables`. A distinct constructor table
configuration is built from the combination of flags given, in order. For
example, to only generate distinct constructor tables for a few specific
constructors and no others, just pass
`-fdistinct-constructor-tables-only=C1,...,CN`.
This flag can be supplied multiple times to extend the set of
constructors to generate a distinct info table for.
You can disable generation of distinct constructor tables for all
configurations by passing `-fno-distinct-constructor-tables`.
The various configurations of these flags is included in the `DynFlags`
fingerprints, which should result in the expected recompilation logic.
Adds a test that checks for distinct tables for various given or omitted
constructors.
Updates CountDepsAst and CountDepsParser tests to account for new dependencies.

Don't prematurely final-zonk PatSyn declarations
This commit makes GHC hold off on the final zonk for pattern synonym
declarations, in 'GHC.Tc.TyCl.PatSyn.tc_patsyn_finish'.
This accommodates the fact that pattern synonym declarations without a
type signature can contain unfilled metavariables, e.g. if the RHS of
the pattern synonym involves view-patterns whose type mentions promoted
(level 0) metavariables. Just like we do for ordinary function bindings,
we should allow these metavariables to be settled later, instead of
eagerly performing a final zonk-to-type.
Now, the final zonking-to-type for pattern synonyms is performed in
GHC.Tc.Module.zonkTcGblEnv.

Move code-gen aux symbols from ghc-internal to rts
These symbols were all previously defined in ghc-internal and made the
dependency structure awkward, where the rts may refer to some of these
symbols and had to work around that circular dependency the way
described in #26166.
Moreover, the code generator will produce code that uses these symbols!
Therefore, they should be available in the rts:
PRINCIPLE: If the code generator may produce code which uses this
symbol, then it should be defined in the rts rather than, say,
ghc-internal.
That said, the main motivation is towards fixing #26166.

This resolves #26166, a bug due to new constraints placed by Apple's
linker on undefined references.
One source of such references in the RTS is the many symbols referenced
in ghc-internal. To mitigate #26166, we make these references dynamic,
as described in Note [RTS/ghc-internal interface].

Add hints for unsolved HasField constraints
This commit adds hints and explanations for unsolved 'HasField'
constraints.
GHC will now provide additional explanations for an unsolved constraint
of the form 'HasField fld_name rec_ty fld_ty'; the details are laid out in
Note [Error messages for unsolved HasField constraints], but briefly:
1. Provide similar name suggestions (e.g. mis-spelled field name)
and import suggestions (record field not in scope).
These result in actionable 'GhcHints', which is helpful to provide
code actions in HLS.
2. Explain why GHC did not solve the constraint, e.g.:
- 'fld_name' is not a string literal (e.g. a type variable)
- 'rec_ty' is a TyCon without any fields, e.g. 'Int' or 'Bool'.
- 'fld_ty' contains existentials variables or foralls.
- The record field is a pattern synonym field (GHC does not generate
HasField instances for those).
- 'HasField' is a custom 'TyCon', not actually the built-in
'HasField' typeclass from 'GHC.Records'.
On the way, we slightly refactor the mechanisms for import suggestions
in GHC.Rename.Unbound. This is to account for the fact that, for
'HasField', we don't care whether the field is imported qualified or
unqualified. 'importSuggestions' was refactored, we now have
'sameQualImportSuggestions' and 'anyQualImportSuggestions'.

OccAnal: Be stricter for better compiler perf.
In particular we are now stricter:
* When combining usageDetails.
* When computing binder info.
In combineUsageDetails when combining the underlying adds we compute a
new `LocalOcc` for each entry by combining the two existing ones.
Rather than wait for those entries to be forced down the road we now
force them immediately. Speeding up T26425 by about 10% with little
effect on the common case.
We also force binders we put into the Core AST everywhere now.
Failure to do so risks leaking the occ env used to set the binders
OccInfo.
For T26425 compiler residency went down by a factor of ~10x.
Compile time also improved by a factor of ~1.6.

Fix namespace specifiers in subordinate exports (#12488)
This patch fixes an oversight in the `lookupChildrenExport` function that
caused explicit namespace specifiers of subordinate export items to be
ignored:
module M (T (type A)) where -- should be rejected
data T = A
Based on the `IEWrappedName` data type, there are 5 cases to consider:
1. Unadorned name: P(X)
2. Named default: P(default X)
3. Pattern synonym: P(pattern X)
4. Type name: P(type X)
5. Data name: P(data X)
Case 1 is already handled correctly; cases 2 and 3 are parse errors; and
it is cases 4 and 5 that we are concerned with in this patch.
Following the precedent established in `LookupExactName`, we introduce
a boolean flag in `LookupChildren` to control whether to look up in all
namespaces or in a specific one. If an export item is accompanied by an
explicit namespace specifier `type` or `data`, we restrict the lookup in
`lookupGRE` to a specific namespace.
The newly introduced diagnostic `TcRnExportedSubordinateNotFound`
provides error messages and suggestions more tailored to this context
than the previously used `reportUnboundName`.

wasm: support running dyld fully client side in the browser
This commit refactors the wasm dyld script so that it can be used to
load and run wasm shared libraries fully client-side in the browser
without needing a wasm32-wasi-ghci backend:
- A new `DyLDBrowserHost` class is exported, which runs in the browser
and uses the in-memory vfs without any RPC calls. This meant to be
used to create a `rpc` object for the fully client side use cases.
- The exported `main` function now can be used to load user-specified
shared libraries, and the user can use the returned `DyLD` instance
to run their own exported Haskell functions.
- The in-browser wasi implementation is switched to
https://github.com/haskell-wasm/browser_wasi_shim for bugfixes and
major performance improvements not landed upstream yet.
- When being run by deno, it now correctly switches to non-nodejs code
paths, so it's more convenient to test dyld logic with deno.
See added comments for details, as well as the added `playground001`
test case for an example of using it to build an in-browser Haskell
playground.

Refactor fundep solving
This commit is a large-scale refactor of the increasingly-messy code that
handles functional dependencies. It has virtually no effect on what compiles
but improves error messages a bit. And it does the groundwork for #23162.
The big picture is described in
Note [Overview of functional dependencies in type inference]
in GHC.Tc.Solver.FunDeps
* New module GHC.Tc.Solver.FunDeps contains all the fundep-handling
code for the constraint solver.
* Fundep-equalities are solved in a nested scope; they may generate
unifications but otherwise have no other effect.
See GHC.Tc.Solver.FunDeps.solveFunDeps
The nested needs to start from the Givens in the inert set, but
not the Wanteds; hence a new function `resetInertCans`, used in
`nestFunDepsTcS`.
* That in turn means that fundep equalities never show up in error
messages, so the complicated FunDepOrigin tracking can all disappear.
* We need to be careful about tracking unifications, so we kick out
constraints from the inert set after doing unifications. Unification
tracking has been majorly reformed: see Note [WhatUnifications] in
GHC.Tc.Utils.Unify.
A good consequence is that the hard-to-grok `resetUnificationFlag`
has been replaced with a simpler use of
`reportCoarseGrainUnifications`
Smaller things:
* Rename `FunDepEqn` to `FunDepEqns` since it contains multiple
type equalities.

QuickLook's tcInstFun should make instantiation variables directly
tcInstFun must make "instantiation variables", not regular
unification variables, when instantiating function types. That was
previously implemented by a hack: set the /ambient/ level to QLInstTyVar.
But the hack finally bit me, when I was refactoring WhatUnifications.
And it was always wrong: see the now-expunged (TCAPP2) note.
This commit does it right, by making tcInstFun call its own
instantiation functions. That entails a small bit of duplication,
but the result is much, much cleaner.

Build implication for constraints from (static e)
This commit addresses #26466, by buiding an implication for the
constraints arising from a (static e) form. The implication has
a special ic_info field of StaticFormSkol, which tells the constraint
solver to use an empty set of Givens.
See (SF3) in Note [Grand plan for static forms]
in GHC.Iface.Tidy.StaticPtrTable
This commit also reinstates an `assert` in GHC.Tc.Solver.Equality.
The test `StaticPtrTypeFamily` was failing with an assertion failure,
but it now works.

Improve tracking of rewriter-sets
This refactor substantially improves the treatment of so-called
"rewriter-sets" in the constraint solver.
The story is described in the rewritten
Note [Wanteds rewrite Wanteds: rewriter-sets]
in GHC.Tc.Types.Constraint
Some highlights
* Trace the free coercion holes of a filled CoercionHole,
in CoercionPlusHoles. See Note [Coercion holes] (COH5)
This avoids taking having to take the free coercion variables
of a coercion when zonking a rewrriter-set
* Many knock on changes
* Make fillCoercionHole take CoercionPlusHoles as its argument
rather than to separate arguments.
* Similarly setEqIfWanted, setWantedE, wrapUnifierAndEmit.
* Be more careful about passing the correct CoHoleSet to
`rewriteEqEvidence` and friends
* Make kickOurAfterFillingCoercionHole more clever. See
new Note [Kick out after filling a coercion hole]
Smaller matters
* Rename RewriterSet to CoHoleSet
* Add special-case helper `rewriteEqEvidenceSwapOnly`

Do not treat CoercionHoles as free variables in coercions
This fixes a long-standing wart in the free-variable finder;
now CoercionHoles are no longer treated as a "free variable"
of a coercion.
I got big and unexpected performance regressions when making
this change. Turned out that CallArity didn't discover that
the free variable finder could be eta-expanded, which gave very
poor code.
So I re-used Note [The one-shot state monad trick] for Endo,
resulting in GHC.Utils.EndoOS. Very simple, big win.

rts: fix eager black holes: record mutated closure and fix assertion
This fixes two problems with handling eager black holes, introduced
by a1de535f762bc23d4cf23a5b1853591dda12cdc9.
- the closure mutation must be recorded even for eager black holes,
since the mutator has mutated it before calling threadPaused
- The assertion that an unmarked eager black hole must be owned by
the TSO calling threadPaused is incorrect, since multiple threads
can race to claim the black hole.

Fix assertion in `postStringLen` to account for \0 byte
We fix the assertion to handle trailing \0 bytes in `postStringLen`.
Before this change, the assertion looked like this:
ASSERT(eb->begin + eb->size > eb->pos + len + 1);
Let's assume some values to see why this is actually off by one:
eb->begin = 0
eb->size = 1
eb->pos = 0
len = 1
then the assertion would trigger correctly:
0 + 1 > 0 + 1 + 1 => 1 > 2 => false
as there is not enough space for the \0 byte (which is the trailing +1).
However, if we change `eb->size = 2`, then we do have enough space for a
string of length 1, but the assertion still fails:
0 + 2 > 0 + 1 + 1 => 2 > 2 => false
Which causes the assertion to fail if there is exactly enough space for
the string with a trailing \0 byte.
Clearly, the assertion should be `>=`!
If we switch around the operand, it should become more obvious that `<=`
is the correct comparison:
ASSERT(eb->pos + len + 1 <= eb->begin + eb->size);
This is expresses more naturally that the current position plus the
length of the string (and the null byte) must be smaller or equal to the
overall size of the buffer.
This change also is in line with the implementation in
`hasRoomForEvent` and `hasRoomForVariableEvent`:
```
StgBool hasRoomForEvent(EventsBuf *eb, EventTypeNum eNum)
{
uint32_t size = ...;
if (eb->pos + size > eb->begin + eb->size)
...
```
the check `eb->pos + size > eb->begin + eb->size` is identical to
`eb->pos + size <= eb->begin + eb->size` plus a negation.

rts: use computed goto for instruction dispatch in the bytecode interpreter
This patch uses computed goto for instruction dispatch in the bytecode
interpreter. Previously instruction dispatch is done by a classic
switch loop, so executing the next instruction requires two jumps: one
to the start of the switch loop and another to the case block based on
the instruction tag. By using computed goto, we can build a jump table
consisted of code addresses indexed by the instruction tags
themselves, so executing the next instruction requires only one jump,
to the destination directly fetched from the jump table.
Closes #12953.

Correct hasFixedRuntimeRep in matchExpectedFunTys
This commit fixes a bug in the representation-polymormorphism check in
GHC.Tc.Utils.Unify.matchExpectedFunTys. The problem was that we put
the coercion resulting from hasFixedRuntimeRep in the wrong place,
leading to the Core Lint error reported in #26528.
The change is that we have to be careful when using 'mkWpFun': it
expects **both** the expected and actual argument types to have a
syntactically fixed RuntimeRep, as explained in Note [WpFun-FRR-INVARIANT]
in GHC.Tc.Types.Evidence.
On the way, this patch improves some of the commentary relating to
other usages of 'mkWpFun' in the compiler, in particular in the view
pattern case of 'tc_pat'. No functional changes, but some stylistic
changes to make the code more readable, and make it easier to understand
how we are upholding the WpFun-FRR-INVARIANT.

Preserve user-written kinds in data declarations
This commit ensures that we preserve the user-written kind for data
declarations, e.g. in
type T2T = Type -> Type
type D :: T2T
data D a where { .. }
that we preserve the user-written kind of D as 'T2T', instead of
expanding the type synonym 'T2T' during kind checking.
We do this by storing 'tyConKind' separately from 'tyConResKind'. This
means that 'tyConKind' is not necessarily equal to
'mkTyConKind binders res_kind', as e.g. in the above example the former
is 'T2T' while the latter is 'Type -> Type'.
This is explained in Note [Preserve user-written TyCon kind] in GHC.Core.TyCon.
This is particularly important for Haddock, as the kinds stored in
interface files affect the generated documentation, and we want to
preserve the user-written types as much as possible.

Store user-written datacon tvs in interface files
This commit ensures we store the user-written quantified type variables
of data constructors in interface files, e.g. in
data D a where
MkD1 :: forall x. x -> D x
MkD2 :: forall u v. u -> v -> D v
The previous behaviour was to rename the universal variables to match
the universal variables of the data constructor. This was undesirable
because the names that end up in interface files end up mattering for
generated Haddock documentation; it's better to preserve the user-written
type variables.
Moreover, the universal variables may not have been user-written at all,
e.g. in an example such as:
type T2T = Type -> Type
data G :: T2T where
MkG :: forall x. D x
Here GHC will invent the type variable name 'a' for the first binder of
the TyCon G. We really don't want to then rename the user-written 'x'
into the generated 'a'.

DataCon univ_tvs names: pick TyCon over inferred
This commit changes how we compute the names of universal type variables
in GADT data constructors. This augments the existing logic that chose
which type variable name to use, in GHC.Tc.TyCl.mkGADTVars. We continue
to prefer DataCon tv names for user-written binders, but we now prefer
TyCon tv names for inferred (non-user-written) DataCon binders.
This makes a difference in examples such as:
type (:~~:) :: k1 -> k2 -> Type
data a :~~: b where
HRefl :: a :~~: a
Before this patch, we ended up giving HRefl the type:
forall {k2}. forall (a :: k2). a :~~: a
whereas we now give it the type:
forall {k1}. forall (a :: k1). a :~~: a
The important part isn't really 'k1' or 'k2', but more that the inferred
type variable names of the DataCon can be arbitrary/unpredictable (as
they are chosen by GHC and depend on how unification proceeds), so it's
much better to use the more predictable TyCon type variable names.

Store # eta binders in TyCon and use for Haddock
This commit stores the number of TyCon binders that were introduced by
eta-expansion (by the function GHC.Tc.Gen.HsType.splitTyConKind).
This is then used to pretty-print the TyCon as the user wrote it, e.g.
for
type Effect :: (Type -> Type) -> Type -> Type
data State s :: Effect where {..} -- arity 3
GHC will eta-expand the data declaration to
data State s a b where {..}
but also store in the 'TyCon' that the number of binders introduced by
this eta expansion is 2. This allows us, in
'Haddock.Convert.synifyTyConKindSig', to recover the original user-written
syntax, preserving the user's intent in Haddock documentation.
See Note [Inline kind signatures with GADTSyntax] in Haddock.Convert.

localRegistersConflict: account for assignment LHS
This commit fixes a serious oversight in GHC.Cmm.Sink.conflicts,
specifically the code that computes which local registers conflict
between an assignment and a Cmm statement.
If we have:
assignment: <local_reg> = <expr>
node: <local_reg> = <other_expr>
then clearly the two conflict, because we cannot move one statement past
the other, as they assign two different values to the same local
register. (Recall that 'conflicts (local_reg,expr) node' is False if and
only if the assignment 'local_reg = expr' can be safely commuted past
the statement 'node'.)
The fix is to update 'GHC.Cmm.Sink.localRegistersConflict' to take into
account the following two situations:
(1) 'node' defines the LHS local register of the assignment,
(2) 'node' defines a local register used in the RHS of the assignment.
The bug is precisely that we were previously missing condition (1).

Update assigned register format when spilling
When we come to spilling a register to put new data into it, in
GHC.CmmToAsm.Reg.Linear.allocRegsAndSpill_spill, we need to:
1. Spill the data currently in the register. That is, do a spill
with a format that matches what's currently in the register.
2. Update the register assignment, allocating a virtual register to
this real register, but crucially **updating the format** of this
assignment.
Due to shadowing in the Haskell code for allocRegsAndSpill_spill, we
were mistakenly re-using the old format. This could lead to a situation
where:
a. We were using xmm6 to store a Double#.
b. We want to store a DoubleX2# into xmm6, so we spill the current
content of xmm6 to the stack using a scalar move (correct).
c. We update the register assignment, but we fail to update the format
of the assignment, so we continue to think that xmm6 stores a
Double# and not a DoubleX2#.
d. Later on, we need to spill xmm6 because it is getting clobbered by
another instruction. We then decide to only spill the lower 64 bits
of the register, because we still think that xmm6 only stores a
Double# and not a DoubleX2#.

JS: support more than 128 registers (#26558)
The JS backend only supported 128 registers (JS variables/array slots
used to pass function arguments). It failed in T26537 when 129
registers were required.
This commit adds support for more than 128 registers: it is now limited to
maxBound :: Int (compiler's Int). If we ever go above this threshold the
compiler now panics with a more descriptive message.
A few built-in JS functions were assuming 128 registers and have been
rewritten to use loops. Note that loops are only used for "high"
registers that are stored in an array: the 31 "low" registers are still
handled with JS global variables and with explicit switch-cases to
maintain good performance in the most common cases (i.e. few registers
used). Adjusting the number of low registers is now easy: just one
constant to adjust (GHC.StgToJS.Regs.lowRegsCount).
No new test added: T26537 is used as a regression test instead.

SimpleOpt: refactor & push coercions into lambdas
This commit improves the simple optimiser (in GHC.Core.SimpleOpt)
in a couple of ways:
- The logic to push coercion lambdas is shored up.
The function 'pushCoercionIntoLambda' used to be called in 'finish_app',
but this meant we could not continue to optimise the program after
performing this transformation.
Now, we call 'pushCoercionIntoLambda' as part of 'simple_app'.
Doing so can be important when dealing with unlifted newtypes,
as explained in Note [Desugaring unlifted newtypes].
- The code is re-structured to avoid duplication and out-of-sync
code paths.
Now, 'simple_opt_expr' defers to 'simple_app' for the 'App', 'Var',
'Cast' and 'Lam' cases. This means all the logic for those is
centralised in a single place (e.g. the 'go_lam' helper function).
To do this, the general structure is brought a bit closer to the
full-blown simplifier, with a notion of 'continuation'
(see 'SimpleContItem').
This commit also modifies GHC.Core.Opt.Arity.pushCoercionIntoLambda to
apply a substitution (a slight generalisation of its existing implementation).

Improve typechecking of data constructors
This commit changes the way in which we perform typecheck data
constructors, in particular how we make multiplicities line up.
Now, impedance matching occurs as part of the existing subsumption
machinery. See the revamped Note [Typechecking data constructors] in
GHC.Tc.Gen.App, as well as Note [Polymorphisation of linear fields]
in GHC.Core.Multiplicity.
This allows us to get rid of a fair amount of hacky code that was
added with the introduction of LinearTypes; in particular the logic of
GHC.Tc.Gen.Head.tcInferDataCon.

Make PmLit be in Ord, and use it in Map

data PmAltConSet = PACS !(UniqDSet ConLike) ![PmLit]
to
data PmAltConSet = PACS !(UniqDSet ConLike) !(Map PmLit PmLit)
This matters when doing pattern-match overlap checking, when there
is a very large set of patterns. For most programs it makes
no difference at all.
For the N=5000 case of the repro case in #26514, compiler
mutator time (with `-fno-code`) goes from 1.9s to 0.43s.
All for the price for an Ord instance for PmLit

mkCast: weaken bad cast warning for multiplicity
This commit weakens the warning message emitted when constructing a bad
cast in mkCast to ignore multiplicity.
Justification: since b33284c7, GHC uses sub-multiplicity coercions to
typecheck data constructors. The coercion optimiser is free to discard
these coercions, both for performance reasons, and because GHC's Core
simplifier does not (yet) preserve linearity.
We thus weaken 'mkCast' to use 'eqTypeIgnoringMultiplicity' instead of
'eqType', to avoid getting many spurious warnings about mismatched
multiplicities.

rts: Fix a deadlock with eventlog flush interval and RTS shutdown
The ghc_ticker thread attempts to flush at the eventlog tick interval, this requires
waiting to take all capabilities.
At the same time, the main thread is shutting down, the schedule is
stopped and then we wait for the ticker thread to finish.
Therefore we are deadlocked.
The solution is to use `newBoundTask/exitMyTask`, so that flushing can
cooperate with the scheduler shutdown.

SimpleOpt: don't subst in pushCoercionIntoLambda
It was noticed in #26589 that the change in 15b311be was incorrect:
the simple optimiser carries two different substitution-like pieces of
information: 'soe_subst' (from InVar to OutExpr) and 'soe_inl'
(from InId to InExpr). It is thus incorrect to have 'pushCoercionIntoLambda'
apply the substitution from 'soe_subst' while discarding 'soe_inl'
entirely, which is what was done in 15b311be.
Instead, we change back pushCoercionIntoLambda to take an InScopeSet,
and optimise the lambda before calling 'pushCoercionIntoLambda' to avoid
mixing InExpr with OutExpr, or mixing two InExpr with different
environments. We can then call 'soeZapSubst' without problems.

Namespace-specified wildcards in import/export lists (#25901)
This change adds support for top-level namespace-specified wildcards
`type ..` and `data ..` to import and export lists.
Examples:
import M (type ..) -- imports all type and class constructors from M
import M (data ..) -- imports all data constructors and terms from M
module M (type .., f) where
-- exports all type and class constructors defined in M,
-- plus the function 'f'
The primary intended usage of this feature is in combination with module
aliases, allowing namespace disambiguation:
import Data.Proxy as T (type ..) -- T.Proxy is unambiguously the type constructor
import Data.Proxy as D (data ..) -- D.Proxy is unambiguously the data constructor
The patch accounts for the interactions of wildcards with:
* Imports with `hiding` clauses
* Import warnings -Wunused-imports, -Wdodgy-imports
* Export warnings -Wduplicate-exports, -Wdodgy-exports
Summary of the changes:
1. Move the NamespaceSpecifier type from GHC.Hs.Binds to GHC.Hs.Basic,
making it possible to use it in more places in the AST.
2. Extend the AST (type: IE) with a representation of `..`, `type ..`,
and `data ..` (constructor: IEWholeNamespace). Per the proposal, the
plain `..` is always rejected with a dedicated error message.
3. Extend the grammar in Parser.y with productions for `..`, `type ..`,
and `data ..` in both import and export lists.
4. Implement wildcard imports by updating the `filterImports` function
in GHC.Rename.Names; the logic for IEWholeNamespace is roughly
modeled after the Nothing (no explicit import list) case.
5. Implement wildcard exports by updating the `exports_from_avail`
function in GHC.Tc.Gen.Export; the logic for IEWholeNamespace is
closely modeled after the IEModuleContents case.
6. Refactor and extend diagnostics to report the new warnings and
errors. See PsErrPlainWildcardImport, DodgyImportsWildcard,
PsErrPlainWildcardExport, DodgyExportsWildcard,
TcRnDupeWildcardExport.
Note that this patch is specifically about top-level import/export
items. Subordinate import/export items are left unchanged.

rts: Handle overflow of ELF section header string table
If the section header string table is stored in a section greater
than or equal to SHN_LORESERVE (0xff00), the 16-bit field e_shstrndx
in the ELF header does not contain the section number, but rather
an overflow value SHN_XINDEX (0xffff) indicating that we need to look
elsewhere.
This fixes the linker by not using e_shstrndx directly but calling
elf_shstrndx, which correctly handles the SHN_XINDEX value.

Load bytecode libraries to satisfy package dependencies
This commit allows you to use a bytecode library to satisfy a package
dependency when using the interpreter.
If a user enables `-fprefer-byte-code`, then if a package provides a
bytecode library, that will be loaded and used to satisfy the
dependency.
The main change is to separate the relevant parts of the `LoaderState`
into external and home package byte code. Bytecode is loaded into either
the home package or external part (similar to HPT/EPS split), HPT
bytecode can be unloaded. External bytecode is never unloaded.
The unload function has also only been called with an empty list of
"stable linkables" for a long time. It has been modified to directly
implement a complete unloading of the home package bytecode linkables.
At the moment, the bytecode libraries are found in the "library-dirs"
field from the package description. In the future when `Cabal`
implements support for "bytecode-library-dirs" field, we can read the
bytecode libraries from there. No changes to the Cabal submodule are
necessary at the moment.
Four new tests are added in testsuite/tests/cabal, which generate fake
package descriptions and test loading the libraries into GHCi.

driver: don't expect nodes to exist when checking paths between them
In `mgQueryZero`, previously node lookups were expected to never fail,
i.e. it was expected that when calculating the path between two nodes in
a zero level import graph, both nodes would always exist. This is not
the case, e.g. in some situations involving exact names (see the
test-case). The fix is to first check whether the node is present in the
graph at all, instead of panicking, just to report that there is no
path.

rts: Fix object file format detection in loadArchive
Commit 76d1041dfa4b96108cfdd22b07f2b3feb424dcbe seems to
have introduced this bug, ultimately leading to failure of
test T11788. I can only theorize that this test isn't run
in upstream's CI, because they don't build a static GHC.
The culprit is that we go through the thin archive, trying
to follow the members on the filesystem, but don't
re-identify the new object format of the member. This pins
`object_fmt` to `NotObject` from the thin archive.
Thanks to @angerman for spotting this.

ci: Try using multi repl in ghc-in-ghci test
This should be quite a bit faster than the ./hadrian/ghci command as it
doesn't properly build all the dependencies.

Stack.Decode: Don't error on bitmap size 0
A RET_BCO may have a bitmap with no payload.
In that case, the bitmap = 0.
One can observe this by using -ddump-bcos and interpreting
```
main = pure ()
```
Observe, for instance, that the BCO for this main function has size 0:
```
ProtoBCO Main.main#0:
\u []
break<main:Main,0>() GHC.Internal.Base.pure
GHC.Internal.Base.$fApplicativeIO GHC.Internal.Tuple.()
bitmap: 0 []
BRK_FUN <breakarray> main:Main 0 <cc>
PACK () 0
PUSH_G GHC.Internal.Base.$fApplicativeIO
PUSH_APPLY_PP
PUSH_G GHC.Internal.Base.pure
ENTER
```
Perhaps we never tried to decode a stack in which a BCO like this was
present. However, for the debugger, we want to decode stacks of threads
stopped at breakpoints, and these kind of BCOs do get on a stack under
e.g. `stg_apply_interp_info` frames.
See the accompanying test in the next commit for an example to trigger
the bug this commit fixes.
Fixes #26640

Narrow before optimising MUL/DIV/REM into shifts
The MUL/DIV/REM operations can be optimised into shifts when one of the
operands is a constant power of 2. However, as literals in Cmm are
stored as 'Integer', for this to be correct we first need to narrow the
literal to the appropriate width before checking whether the literal is
a power of 2.
Fixes #25664

Narrow before optimising MUL/DIV/REM into shifts
The MUL/DIV/REM operations can be optimised into shifts when one of the
operands is a constant power of 2. However, as literals in Cmm are
stored as 'Integer', for this to be correct we first need to narrow the
literal to the appropriate width before checking whether the literal is
a power of 2.
Fixes #25664

+-- which wraps round to 2^(_w - 1), and multiplying by -2^(_w - 1) is indeed

[Git][ghc/ghc][wip/int-index/imp-exp-wildcards] Subordinate namespace-specified wildcards
by Vladislav Zavialov (＠int-index) 09 Dec '25

Vladislav Zavialov pushed to branch wip/int-index/imp-exp-wildcards at Glasgow Haskell Compiler / GHC

Subordinate namespace-specified wildcards
Add support for subordinate namespace-specified wildcards
`X(type ..)` and `X(data ..)` to import and export lists.
Examples:
import M (Cls(type ..)) -- imports Cls and all its associated types
import M (Cls(data ..)) -- imports Cls and all its methods
module M (R(data ..), C(type ..)) where
-- exports R and all its data constructors and record fields;
-- exports C and all its associated types, but not its methods
The scope of this change is limited to the case where the wildcard is the only
subordinate import/export item, whereas the more complex forms `X(type .., f)`
or `X(type .., data ..)` are unsupported and raise the newly introduced
PsErrUnsupportedExplicitNamespace error. This restriction may be lifted later.
Summary of the changes:
1. Refactor IEThingAll to store its extension field XIEThingAll as a record
IEThingAllExt instead of a tuple.
2. Extend the AST by adding a NamespaceSpecifier field to IEThingAllExt,
representing an optional namespace specifier `type` or `data` in front
of a subordinate wildcard `X(..)`.
3. Extend the grammar in Parser.y with productions for `type ..` and `data ..`
in subordinate import/export items.
4. Introduce `filterByNamespaceGREs` to filter [GlobalRdrElt] by a
NamespaceSpecifier; use it in `filterImports` and `exports_from_avail`
to account for the namespace specifier in IEThingAll.
5. Improve diagnostics by storing more information in DodgyImportsEmptyParent
and DodgyExportsEmptyParent.
Test cases:
