---
--- Normal @UniqFM@ when you turn it into a list will use

+{- Note [Deterministic UniqFM]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+When you enumerate the elements of a normal `UniqFM`, using `nonDetUFMToList`, you
+get the elements back in the order of their `Unique` keys. This can mess up deterministic
+compilation; see Note [Unique Determinism] in GHC.Types.Unique.
+
+This module defines /deterministic/ unique-keyed finite maps, `UniqDFM`, which have
+the following property:
+
+ (UniqDFM property) The function `udfmToList` returns the elements in the order
+ in which they were inserted; that is, in order of their "insertion date".
+
+ In particular, the order of elements does not depend on:
+ * The Unique key for those elements
+ * How existing entries are updated with `alterUDFM`; updating an element does not change
+ its insertion date.
+
+ If an element is completely deleted and then again inserted, the latter insertion counts as its
+ insertion date.
+
+ When we take (m1 `plusUDFM` m2), the insertion dates of elements in the smaller map are
+ adjusted to be after all those in the bigger map.
+
+Updating an existing entry keeps its original position in the order.
+This means `alterUDFM` is consistent with `addToUDFM` and `adjustUDFM`,
+so that for example `alterUDFM id k = id` and `alterUDFM (fmap f) k = adjustUDFM f k`
+
+It also keeps the order stable for
+maps whose entries are updated many times. The instance environments are
+the main example: inserting an instance updates the entry of its class in a
+DNameEnv, and when updates moved keys to the end the order of instances shown
+by :info depended on the order in which interfaces happened to be loaded
+(#27532). Now a class keeps its place once its first instance is added, so
+loading further interfaces cannot change the order.
+
+`foldUDFM` also preserves determinism:
+
+ foldUDFM k z m = foldr k z (eltsUDFM m)
+
+Implementation
+~~~~~~~~~~~~~~
+There's more than one way to implement this. The implementation here tags
+every value with the insertion time that can later be used to sort the
+values when asked to convert to a list.
+
+There is an implementation cost: each element is given a serial number
+as it is added, and `udfmToList` sorts its result by this serial
+number. So you should only use `UniqDFM` if you need the deterministic

Resolving many TTG related orphan type-class instances
This is part a technical debt removal effort made possible now
that separating out the AST via TTG has come to a close.
As the AST in 'L.H.S' has been incrementally separated from the GHC internals,
there are many accumulated orphan instance of 'Binary', 'NFData', 'Outputable',
and 'Uniquable'. The orphan instance of data-types from within 'L.H.S' have had
their orphan instances moved to either:
1. The module which defines the data-type
2. The module which defines the type-class;
i.e. moving an orphan 'Binary' instance to 'GHC.Utils.Binary'
Orphan instances resolved (37):

Eliminate STM_AWOKEN
It was used as nullary closure for the block_info.closure in the case of
a thread being awoken after an STM transaction.
However, while it was written, it was never read, so contributed nothing
to the behaviour. Furthermore, in the only place it was set (in
tryWakeupThread) the why_blocked was immediately overwritten by the
NotBlocked status, and the block_info was updated accordingly (by
appendToRunQueue).
So it didn't even serve a purpose of clarifying an intermediate state,
there really was no such intermediate state.
Cleaning this up will allow the BlockedOnSTM case to follow the same
pattern as the other why_blocked cases that do not use the block_info,
and in turn this reduces the number of different categories.

Add a proper mapping to eventlog external thread stop status
That is the mapping from rts-internal codes, to the coes used in the
status field in the eventlog EVENT_STOP_THREAD event.
See issue #9003 for what goes wrong when we mess this up. In that
ticket, people note that we should really not require the internal
tso->why_blocked codes to leak into the external eventlog thread stop
codes. The same principle applies to the StgThreadReturnCode.
This change properly separates them, and explicitly maps between them
using a pair of (compact, constant) tables. These tables are pretty
small (with no alignment constraints) and will soon shrink so it seems
a sensible tradeoff.
We also introduce and use proper EVENT_STOP_THREAD constants in the
event log format header. Previously there was not specification in the
code for these (only in the docs): the values were encoded into the
conversion code.
This will allow us to renumber the internal why_blockd codes without
breaking the eventlog output.

Add a tso->block_info.mvar member and use it
in preference to the generic block_info.closure union member, with
casts.
The plan is that when we know what case we're in (via tso->why_blocked)
then we can always access the correct union member, and so we will only
need to access block_info.closure for generic cases where we don't know
or don't care.

Avoid storing to tso->block_info.closure
In one case we can use a specific union member (.prev) instead. In
several cases the stores were in fact redundant because of subsequent
overwrites.
In scavengeTSO we replace setting tso->block_info.closure to a valid
closure, with an assertion that the block_info.unused is already set to
END_TSO_QUEUE which is a valid (static) closure.

96e4749d by Duncan Coutts at 2026-07-23T17:26:18-04:00
Renumber the tso->why_blocked constants
We can do this now because we have separated the internal values from
the external ones used in the eventlog.
This lets us put them back into a deliberate order and consolodate some
gaps.
More importantly, it is a prepation for a slightly more sophisticated
encoding.

Define constants for the existing stg_threadStatuszh return codes
The stg_threadStatuszh reuses the internal tso->why_blocked codes but
also extends them with a couple previously magic values. This is awkward
since we need to know what those magic values are so we don't
accidentally use those values to mean something else. By pulling a
definition up to where the why_blocked codes are defined we will be able
to avoid mistakenly assining those codes some meaning (or just changing
the BlockedThreadComplete, BlockedThreadKilled code if necessary).

42c69ae2 by Duncan Coutts at 2026-07-23T17:26:18-04:00
Extend the tso->why_blocked encoding to indicate block_info closures
We use some bit tricks to cheaply and generically test if a
tso->why_blocked tag implies that the corresponding tso->block_info will
contain a non-trivial valid closure (i.e. not just block_info.unused set
to END_TSO_QUEUE).
In particular we arrange for most why_blocked values to naturally have a
distinguishing bit, but for the BlockedOn{Read,Write,Delay} cases, they
can come in either non-closure or closure forms. We allow an additional
bit to distinguish these cases. The non-closure forms are only from
legacy I/O managers: select and win32-legacy. So this extra bit
mechanism will be able to be retired once the legacy I/O managers are
themselves retired.
This means in a few places we need to untag the why_blocked value before
inspecting it, but in most places we do not.

that are supposed to use block_info.unused == END_TSO_QUEUE, and which
cases are allowed to use BlockInfoForceNonClosure.
This partially enforces the use of why_blocked as a tag for the
block_info union. We could be stricter and check for the correct
expected info table for the closure cases.

Use IsBlockInfoClosure to simplify several tests
In GC and generic traversal we need to know if we should look at the
block_info.closure or not. Now we can do just that using a cheap bit
test on the why_blocked tag.
This fixes issue 26717, where the problem was that some GC modes did not
know when to look at block_info.closure, because the poll I/O manager
uses a closure for BlockedOn{Read,Write} while the select I/O manager
uses a non-closure. Now this information is in the why_blocked tag
itself.

Follow atomic access rules more consistently for tso->why_blocked
The rule is this:
store block_info *before* why_blocked
store why_blocked using store release
load why_blocked using load acquire
load block_info *after* why_blocked
This is a an atomic store release / load acquire pair and (if the reads
are in a separate thread to the writes, and the read receives the value
stored) then this guarantees a full "happens before" relationship of
these stores and loads.
In some cases, we do not need a full load acquire, because we don't read
the block_info at all and so do not need any ordering. In this case we
just need an atomic relaxed load.
This was being followed in most places, but not all. If there's good
reason in any case that we don't need atomic access, then we should
document that in a comment. In the absence of that I think it's easier
to follow the rule everywhere.

EPA: Keep decls together in ClassDecl
Similar to 1718230f4d3d19d8c49c0e5d496cb0fb6f399528 for HsValBindsLR,
this commit updates ClassDecl so that it no longer splits out the
assorted `LHsDecl GhcPs` until the renamer.
It does this by inserting a type family (separate from the classic TTG one) for this.
So
data TyClDecl
...
| ClassDecl {
...
tcdDecls :: XClassDecls pass
with
type instance XClassDecls GhcPs = [LHsDecl GhcPs]
type instance XClassDecls GhcRn = ClassDeclX GhcRn
type instance XClassDecls GhcTc = ClassDeclX GhcTc
data ClassDeclX pass
= ClassDeclX { tcdSigs :: [LSig pass], -- ^ Methods' signatures
tcdMeths :: LHsBinds pass, -- ^ Default methods
tcdATs :: [LFamilyDecl pass], -- ^ Associated types;
tcdATDefs :: [LTyFamDefltDecl pass], -- ^ Associated type defaults
tcdDocs :: [LDocDecl pass] -- ^ Haddock docs

Add -Wdefaulted-callstack
Adds a new warning, -Wdefaulted-callstack, which warns when an implicit
CallStack parameter is defaulted to the empty stack. In particular, this
includes call sites where a function with a HasCallStack constraint is called
from a definition that does *not* provide one. At such call sites the call stack
is cut off and does not include the enclosing definition's callers, which can be
a source of surprise if the user wants complete call stacks.
Closes #27077.

UniqueDFM: alter should preserve insertion order
Before it always inserting new elements at the end.
This is problematic because instances get inserted into the map with
`alterF`, which can change ordering of how instances are printed
with `:info` depending on the order in which we consult interfaces
I expect `alter id k = id` and `alter (fmap f) k = adjust f k`. Moving keys to
the end breaks that (`adjust` already preserves position).

Introduce global unit database cache
As a first step for better sharing of `UnitInfo` across `UnitEnv`,
we introduce a new datatype called `ExternalUnitDatabases`.
It primarily serves as an in-memory representation of *all*
`UnitDatabase`s across `UnitEnv`. This means, if multiple `HomeUnitEnv`s
depend on the same database, one way or another, we make sure that we
don't parse from disk every time.
Instead, we store the in-memory representation in `ExternalUnitDatabases`.
`ExternalUnitDatabaseCache` is the equivalent of `ExternalUnitState` in
the `UnitEnv`. It is a mutable variable wrapping `ExternalUnitDatabases`.
The mutable `ExternalUnitDatabaseCache` is used in `initUnits` to make
sure we don't parse the same unit database multiple times.
Almost by accident, we change the semantics of `initUnits` to honour
modifications to `packageDBFlags`.
The inability to change `packageDBFlags` while also reusing the already
parsed `UnitDatabase`s was reported in #26423 as a bug.
Hence, we think this behaviour change is warranted and acceptable,
especially since it comes with a breaking change to the `initUnits` API.
Add regression test for #26423
Closes #26423

Introduce UnitIndex for global external unit caching
`UnitInfo`s have been observed to cause a lot of memory usage in #27500.
Especially with multiple home units, as the same (external) units are
processed from scratch, even though most of the time we end up with
exactly the same `UnitInfo`.
We introduce a `UnitEnv` global cache that allows us to store external
unit information that is used across all `HomeUnitEnv`s.
The most important change in this commit is the introduction of the `UnitIndex`.
It stores a global mapping of `UnitId` -> `UnitInfo`, and `initUnits`
always uses the cached `UnitInfo` entry to populate each
`HomeUnitEnv`'s `UnitState`.
This allows us to ensure the following property:
> Each `UnitInfo` should be alive exactly once in GHC.
All `UnitState`s should reference 'UnitInfo's stored in the 'UnitIndex'.
This ensured by calling 'initUnits' with the 'UnitIndex'.
In addition, the `ExternalUnitDatabases` may also hold a reference
to each on-disk representation of `UnitInfo`.
This means, we impose an hard upper bound on the number of `UnitInfo`s
alive in the GHC session:
> The number of alive `UnitInfo`s closure objects must be the
> sum of all loaded unit database times two.
We add performance regression tests that make sure the number of live
`UnitInfo` cannot exceed this threshold.
Closes #27500
-------------------------
Metric Decrease:
MultiComponentModules
MultiComponentModulesRecomp
MultiComponentModulesRecomp100
mhu-perf
LinkableUsage02
-------------------------
These metrics increases are especially notable, as we are not even
sharing anything big but merely the global package database with 50
entries.
It shows how careful sharing of `UnitInfo` can improve memory usage.
We expect this to be much more notable when the whole cabal package
database is shared across multiple home units.
`LinkableUsage02` metric decreases on unreg and i386 platform, only.
---
Technical details
To share the `UnitInfo`s correctly, it is important that we extract
the `WireMap` into the `UnitIndex`. At the moment of writing, `WireMap`
must be globally the same for all `HomeUnitEnv`s.
This is important, as we could otherwise not cache the "fully-resolved"
`UnitInfo`, as we don't change the `UnitId` or `unitAbiHash` when
resolving wired-in units. Thus, there could be ambiguities, when the
`WireMap` is not the same for all `UnitState`s across the `UnitEnv`.
We consider a `UnitInfo` fully-resolved, if wired-in units have been
updated, the `UnitInfo` has been validated and variables in the unit
config, such as `${pkgroot}` have been resolved.
Updating the wired-in units requires the `WireMap` to be globally the
same.

hadrian: implement and use writeFileAtomic to fix race condition
This patch implements `writeFileAtomic` in hadrian and change all
invocations of shake non-atomic `writeFile'` to use `writeFileAtomic`,
to avoid multiple hadrian concurrent invocations overwriting the same
in-tree generated file not in the build root directory. Fixes #27536.
Additional notes:
- `writeFileChanged`/`writeFileChangedBS` cannot be made atomic since
it involves reading the file's older version, so their uses are left
alone. It doesn't affect #27536 given their outputs are contained in
the build root directory.
- It's possible to shrink this patch by only making writes outside the
build root directory atomic. But I think it's not worth the effort
for fine grained distinction here, and atomic writes within the
build root directory should also improve robustness of a hadrian
build.
- In the longer term we do want to make a ghc build only generate
files within the build root directory, though that's a lot of work
and outside the scope of this particular bugfix.

EPA: Remove LocatedP from OverlapMode
We have
type LocatedP = GenLocated SrcSpanAnnP
type SrcSpanAnnP = EpAnn AnnPragma
As the first step in removing this in favour of LocatedA which only
captures location, comments and trailing annotations, we remove it
from OverlapMode
We do this by moving the AnnPragma into the TTG extension point
instead.

hadrian: fix HLS support
This patch fixes hadrian's HLS support so one can rely on HLS when
working on the hadrian codebase. Fixes #27480.
Not building/linking shared libraries for hadrian is a severely
premature optimization; this top-level setting in `cabal.project` only
affects home packages while the dependencies in the cabal store are
built with vanilla/dynamic anyway, and even adding dynamic builds to
home packages would not be costly due to cabal's usage of
`-dynamic-too`.

ValBind data type, which is the bind equivalent of ValD, having
constructors for binds and sigs.

testsuite: fix bytecodeIPE test under +ipe flavours
This patch fixes the bytecodeIPE test under +ipe flavours. It used to
fail under +ipe because the RTS is built with IPE info, then
stg_AP_info in RTS carries IPE info, so whereFrom wouldn't return
Nothing. Now the test checks IPE info of a datacon in the ghci-loaded
module which is not affected by whether the RTS is built with IPE info
or not. Fixes #27498.

rts: fix missing UNTAG in stg_readTVarIOzh
This patch fixes missing UNTAG on the current value closure read from
StgTVar. UNTAG is a no-op when it's stg_TREC_HEADER_info which is word
aligned; it may be a tagged closure, and reading info table from the
tagged address is an unaligned load which may cause issues on
platforms with strict alignment requirements.

rts: fix missing UNTAG in stg_control0zh_ll
This patch fixes missing UNTAG on the cont closure returned by
captureContinuationAndAbort. In case it's not NULL,
captureContinuationAndAbort returns a tagged StgContinuation closure,
in which case it must be untagged before accessing the
apply_mask_frame field.
In the past it worked out of luck: when apply_mask_frame was NULL then
mask_frame_offset is also 0 so the control flow didn't diverge to a
wrong path. Still, this is horribly wrong and will crash once
StgContinuation struct is refactored and fields are shuffled around.

compiler: fix redundant AP thunk codegen when not using -ticky-ap-thunk
This patch fixes a double negation confusion in !7525 that results in
some redundant AP thunk code generation when not using
-ticky-ap-thunk. Now, we use `stgToCmmUseStdApThunk` to indicate
whether precomputed AP thunks in the RTS should be used, which
defaults to `True`, unless `-ticky-ap-thunk` is passed.
`-finfo-table-map` now also implies `-ticky-ap-thunk`, since when
doing IPE profiling we want the generated AP thunks to be unique.
Fixes #27502.

base: Display ExceptionContext in WhileHandling's textual description
As originally-implemented the implementation for
`WhileHandling(displayExceptionAnnotation)` would display the
`ExceptionContext` of the exception which it carries (as this was the
behavior of `displayException`, in terms of which
`displayExceptionAnnotation` was implemented).
However, in 284ffab3 the definition of `SomeException(displayException)`
was changed to exclude the `ExceptionContext`. This means that
`WhileHandling(displayExceptionAnnotation)` fails to describe the
provenance of the exception which it captures, greatly limiting its
utility.
Return the implementation to its originally-specified behavior by
implementing `WhileHandling(displayExceptionAnnotation)` in terms of
`displayExceptionWithInfo`.
Fixes #27456.

Coercion optimisation: avoid double-Sym for InstCo
Ticket #27374 pointed out an issue with GHC.Core.Coercion.Opt.optCoercion's
handling of InstCo: it contravened (LC2) in Note [The LiftingContext in optCoercion]
because it applied the ambient 'sym' to a coercion that was then added
to the lifting context substitution.

Move THREADED_RTS-conditional struct members to end of Capability
Accessing members of the Capability struct from CMM code rely on
accessor macros. (The macros are generated by deriveConstants).
These macros have a single definition. This means that the offsets of
all struct members must *not* vary based on THREADED_RTS vs
!THREADED_RTS. This requires that any struct members that are
conditional on THREADED_RTS must occur after the unconditional struct
members. Hence we move all the ones that are conditional on
THREADED_RTS to the end.
Add a deriveConstants entry for the iomgr member of the Capability
struct, which was the motivation for this change.
Add warning messages to help our future selves. Debugging this took me
a couple hours in gdb!

Make the IOManager API use CapIOManager rather than Capability
This makes the API somewhat more self-contained and more consistent.
Now the IOManager API and each of the backends takes just the I/O
manager structure. Previously we had a bit of a mixture, depending on
whether the function needed access to the Capability or just the
CapIOManager.
We still need access to the cap, so we introduce a back reference to
reach the capability, via iomgr->cap.
Convert all uses in select and poll backends, but not win32 ones.
Convert callers in the scheduler and elsewhere.
Also convert the three CMM primops that call IOManager APIs. They just
need to use Capability_iomgr(MyCapability()).

Free per-cap I/O managers during shutdown and forkProcess
Historically this was not strictly necessary. The select and win32
legacy I/O managers did not maintain any dynamically allocated
resources. The new poll one does (an auxillary table), and so this
should be freed.
After forkProcess, all threads get deleted. This includes threads
waiting on I/O or timers. So as of this patch, resetting the I/O
manager is just about tidying things up. For example, for the poll
I/O manager this will reset the size of the AIOP table (which
otherwise grows but never shrinks).
In future however the re-initialising will become neeecessary for
functionality, since some I/O managers will need to re-initialise
wakeup fds that are set CLOEXEC.

Remove wakeupIOManager, ioManagerWakeup and setIOManagerWakeupFd
We no longer need wakeupIOManager for the threaded RTS case, so we can
remove it and the bits only needed to support it. This includes the
pipe/eventfd fd shared between the RTS and the in-library I/O manager
used for waking up the I/O manager thread. The pipe/eventfd still
exists, but it no longer has to be communicated to the RTS, since the
RTS no longer needs to use it.
So we remove the RTS API export setIOManagerWakeupFd, and remove uses of
it within the I/O managers in ghc-internal.

Add interruptIOManager support for poll I/O manager
Uses the FdWakup mechanism.
A quirk we have to cope with is that we now need to poll one more fd --
the wakeup_fd_r -- but this fd has no corresponding entry in the
aiop_table. This is awkward since we have set up our aiop_poll_table to
be an auxilliary table with matching indicies.
The solution this patch uses (and described in the comments) is to have
two tables: struct pollfd *aiop_poll_table, *full_poll_table;
and to have the aiop_poll_table alias the tail of the full_poll_table.
The head entry in the full_poll_table is the extra fd. So we poll the
full_poll_table, while the aiop_poll_table still has matching indicies
with the aiop_table.
Hurrah for C aliasing rules.

Ignore ticks in the pattern-match term oracle
The term-oracle in the pattern-match checker is keyed by a canonical
form of the scrutinee, computed by `makeDictsCoherent`. That canonical
form was tick-sensitive: two occurrences of an otherwise identical
expression that happened to carry different ticks were treated as
distinct values, breaking long-distance information.
This shows up in practice under `-finfo-table-map`, because the
desugarer wraps every record-selector use site in a `SourceNote`
carrying that site's span. For example:
data Box = Box { unBox :: Maybe Int }
f b = case unBox b of
Nothing -> 0
Just _ -> let Just x = unBox b in x
The two `unBox b` expressionss carry different SourceNote spans, the
pattern-match checker sees them as different, the long-distance
information from the outer `Just _` branch never reaches the
let-pattern, and `Just x = unBox b` is wrongly reported as
non-exhaustive.
We now strip all ticks in `makeDictsCoherent`. This is documented as
Wrinkle (UD1) of Note [Unique dictionaries in the TmOracle CoreMap].

Resolving many TTG related orphan type-class instances
This is part a technical debt removal effort made possible now
that separating out the AST via TTG has come to a close.
As the AST in 'L.H.S' has been incrementally separated from the GHC internals,
there are many accumulated orphan instance of 'Binary', 'NFData', 'Outputable',
and 'Uniquable'. The orphan instance of data-types from within 'L.H.S' have had
their orphan instances moved to either:
1. The module which defines the data-type
2. The module which defines the type-class;
i.e. moving an orphan 'Binary' instance to 'GHC.Utils.Binary'

parser: don't suggest ImportQualifiedPost when it is already enabled
-Wprepositive-qualified-module unconditionally attached a hint to
enable ImportQualifiedPost, even when the extension was already on
(as it is by default under GHC2021). Record the extension's state in
the PsWarnImportPreQualified diagnostic and drop the hint when it is
already enabled.

ci: Reduce lint job setup costs
Avoid fetching unnecessary history and submodules for lightweight lint
jobs. Run changelog validation without Hadrian.
Because the lint-author job is now based on the .lint template directly,
we enhance it to allow Git to read from the runner-owned checkouts,
In the previously used .lint-params template, this permissions issue was
addressed via `chown`.
Closes #27521.

Eliminate STM_AWOKEN
It was used as nullary closure for the block_info.closure in the case of
a thread being awoken after an STM transaction.
However, while it was written, it was never read, so contributed nothing
to the behaviour. Furthermore, in the only place it was set (in
tryWakeupThread) the why_blocked was immediately overwritten by the
NotBlocked status, and the block_info was updated accordingly (by
appendToRunQueue).
So it didn't even serve a purpose of clarifying an intermediate state,
there really was no such intermediate state.
Cleaning this up will allow the BlockedOnSTM case to follow the same
pattern as the other why_blocked cases that do not use the block_info,
and in turn this reduces the number of different categories.

Add a proper mapping to eventlog external thread stop status
That is the mapping from rts-internal codes, to the coes used in the
status field in the eventlog EVENT_STOP_THREAD event.
See issue #9003 for what goes wrong when we mess this up. In that
ticket, people note that we should really not require the internal
tso->why_blocked codes to leak into the external eventlog thread stop
codes. The same principle applies to the StgThreadReturnCode.
This change properly separates them, and explicitly maps between them
using a pair of (compact, constant) tables. These tables are pretty
small (with no alignment constraints) and will soon shrink so it seems
a sensible tradeoff.
We also introduce and use proper EVENT_STOP_THREAD constants in the
event log format header. Previously there was not specification in the
code for these (only in the docs): the values were encoded into the
conversion code.
This will allow us to renumber the internal why_blockd codes without
breaking the eventlog output.

Add a tso->block_info.mvar member and use it
in preference to the generic block_info.closure union member, with
casts.
The plan is that when we know what case we're in (via tso->why_blocked)

need to access block_info.closure for generic cases where we don't know
or don't care.

Avoid storing to tso->block_info.closure
In one case we can use a specific union member (.prev) instead. In
several cases the stores were in fact redundant because of subsequent
overwrites.
In scavengeTSO we replace setting tso->block_info.closure to a valid
closure, with an assertion that the block_info.unused is already set to
END_TSO_QUEUE which is a valid (static) closure.

Renumber the tso->why_blocked constants
We can do this now because we have separated the internal values from
the external ones used in the eventlog.
This lets us put them back into a deliberate order and consolodate some
gaps.
More importantly, it is a prepation for a slightly more sophisticated
encoding.

Define constants for the existing stg_threadStatuszh return codes
The stg_threadStatuszh reuses the internal tso->why_blocked codes but
also extends them with a couple previously magic values. This is awkward
since we need to know what those magic values are so we don't
accidentally use those values to mean something else. By pulling a
definition up to where the why_blocked codes are defined we will be able
to avoid mistakenly assining those codes some meaning (or just changing
the BlockedThreadComplete, BlockedThreadKilled code if necessary).

42c69ae2 by Duncan Coutts at 2026-07-23T17:26:18-04:00
Extend the tso->why_blocked encoding to indicate block_info closures
We use some bit tricks to cheaply and generically test if a
tso->why_blocked tag implies that the corresponding tso->block_info will
contain a non-trivial valid closure (i.e. not just block_info.unused set
to END_TSO_QUEUE).
In particular we arrange for most why_blocked values to naturally have a
distinguishing bit, but for the BlockedOn{Read,Write,Delay} cases, they
can come in either non-closure or closure forms. We allow an additional
bit to distinguish these cases. The non-closure forms are only from
legacy I/O managers: select and win32-legacy. So this extra bit
mechanism will be able to be retired once the legacy I/O managers are
themselves retired.
This means in a few places we need to untag the why_blocked value before
inspecting it, but in most places we do not.

Enforce the why_blocked and block_info rules in checkTSO
We now check the cases wher IsBlockInfoClosure should hold, the cases
that are supposed to use block_info.unused == END_TSO_QUEUE, and which
cases are allowed to use BlockInfoForceNonClosure.
This partially enforces the use of why_blocked as a tag for the
block_info union. We could be stricter and check for the correct
expected info table for the closure cases.

Use IsBlockInfoClosure to simplify several tests
In GC and generic traversal we need to know if we should look at the
block_info.closure or not. Now we can do just that using a cheap bit
test on the why_blocked tag.
This fixes issue 26717, where the problem was that some GC modes did not
know when to look at block_info.closure, because the poll I/O manager
uses a closure for BlockedOn{Read,Write} while the select I/O manager
uses a non-closure. Now this information is in the why_blocked tag
itself.

Follow atomic access rules more consistently for tso->why_blocked
The rule is this:
store block_info *before* why_blocked
store why_blocked using store release
load why_blocked using load acquire
load block_info *after* why_blocked
This is a an atomic store release / load acquire pair and (if the reads
are in a separate thread to the writes, and the read receives the value
stored) then this guarantees a full "happens before" relationship of
these stores and loads.
In some cases, we do not need a full load acquire, because we don't read
the block_info at all and so do not need any ordering. In this case we
just need an atomic relaxed load.
This was being followed in most places, but not all. If there's good
reason in any case that we don't need atomic access, then we should
document that in a comment. In the absence of that I think it's easier
to follow the rule everywhere.

EPA: Keep decls together in ClassDecl
Similar to 1718230f4d3d19d8c49c0e5d496cb0fb6f399528 for HsValBindsLR,
this commit updates ClassDecl so that it no longer splits out the
assorted `LHsDecl GhcPs` until the renamer.
It does this by inserting a type family (separate from the classic TTG one) for this.
So
data TyClDecl
...
| ClassDecl {
...
tcdDecls :: XClassDecls pass
with
type instance XClassDecls GhcPs = [LHsDecl GhcPs]
type instance XClassDecls GhcRn = ClassDeclX GhcRn
type instance XClassDecls GhcTc = ClassDeclX GhcTc
data ClassDeclX pass
= ClassDeclX { tcdSigs :: [LSig pass], -- ^ Methods' signatures
tcdMeths :: LHsBinds pass, -- ^ Default methods
tcdATs :: [LFamilyDecl pass], -- ^ Associated types;
tcdATDefs :: [LTyFamDefltDecl pass], -- ^ Associated type defaults

Add -Wdefaulted-callstack
Adds a new warning, -Wdefaulted-callstack, which warns when an implicit
CallStack parameter is defaulted to the empty stack. In particular, this
includes call sites where a function with a HasCallStack constraint is called
from a definition that does *not* provide one. At such call sites the call stack
is cut off and does not include the enclosing definition's callers, which can be
a source of surprise if the user wants complete call stacks.

UniqueDFM: alter should preserve insertion order
Before it always inserting new elements at the end.
This is problematic because instances get inserted into the map with
`alterF`, which can change ordering of how instances are printed
with `:info` depending on the order in which we consult interfaces
I expect `alter id k = id` and `alter (fmap f) k = adjust f k`. Moving keys to
the end breaks that (`adjust` already preserves position).

Introduce global unit database cache
As a first step for better sharing of `UnitInfo` across `UnitEnv`,
we introduce a new datatype called `ExternalUnitDatabases`.
It primarily serves as an in-memory representation of *all*
`UnitDatabase`s across `UnitEnv`. This means, if multiple `HomeUnitEnv`s
depend on the same database, one way or another, we make sure that we
don't parse from disk every time.
Instead, we store the in-memory representation in `ExternalUnitDatabases`.
`ExternalUnitDatabaseCache` is the equivalent of `ExternalUnitState` in
the `UnitEnv`. It is a mutable variable wrapping `ExternalUnitDatabases`.
The mutable `ExternalUnitDatabaseCache` is used in `initUnits` to make
sure we don't parse the same unit database multiple times.
Almost by accident, we change the semantics of `initUnits` to honour
modifications to `packageDBFlags`.
The inability to change `packageDBFlags` while also reusing the already
parsed `UnitDatabase`s was reported in #26423 as a bug.
Hence, we think this behaviour change is warranted and acceptable,
especially since it comes with a breaking change to the `initUnits` API.
Add regression test for #26423
Closes #26423

Introduce UnitIndex for global external unit caching
`UnitInfo`s have been observed to cause a lot of memory usage in #27500.
Especially with multiple home units, as the same (external) units are
processed from scratch, even though most of the time we end up with
exactly the same `UnitInfo`.
We introduce a `UnitEnv` global cache that allows us to store external
unit information that is used across all `HomeUnitEnv`s.
The most important change in this commit is the introduction of the `UnitIndex`.
It stores a global mapping of `UnitId` -> `UnitInfo`, and `initUnits`
always uses the cached `UnitInfo` entry to populate each
`HomeUnitEnv`'s `UnitState`.
This allows us to ensure the following property:
> Each `UnitInfo` should be alive exactly once in GHC.
All `UnitState`s should reference 'UnitInfo's stored in the 'UnitIndex'.
This ensured by calling 'initUnits' with the 'UnitIndex'.
In addition, the `ExternalUnitDatabases` may also hold a reference
to each on-disk representation of `UnitInfo`.
This means, we impose an hard upper bound on the number of `UnitInfo`s
alive in the GHC session:
> The number of alive `UnitInfo`s closure objects must be the
> sum of all loaded unit database times two.
We add performance regression tests that make sure the number of live
`UnitInfo` cannot exceed this threshold.
Closes #27500
-------------------------
Metric Decrease:
MultiComponentModules
MultiComponentModulesRecomp
MultiComponentModulesRecomp100
mhu-perf
LinkableUsage02
-------------------------
These metrics increases are especially notable, as we are not even
sharing anything big but merely the global package database with 50
entries.
It shows how careful sharing of `UnitInfo` can improve memory usage.
We expect this to be much more notable when the whole cabal package
database is shared across multiple home units.
`LinkableUsage02` metric decreases on unreg and i386 platform, only.
---
Technical details
To share the `UnitInfo`s correctly, it is important that we extract
the `WireMap` into the `UnitIndex`. At the moment of writing, `WireMap`
must be globally the same for all `HomeUnitEnv`s.
This is important, as we could otherwise not cache the "fully-resolved"
`UnitInfo`, as we don't change the `UnitId` or `unitAbiHash` when
resolving wired-in units. Thus, there could be ambiguities, when the
`WireMap` is not the same for all `UnitState`s across the `UnitEnv`.
We consider a `UnitInfo` fully-resolved, if wired-in units have been
updated, the `UnitInfo` has been validated and variables in the unit
config, such as `${pkgroot}` have been resolved.
Updating the wired-in units requires the `WireMap` to be globally the
same.

hadrian: implement and use writeFileAtomic to fix race condition
This patch implements `writeFileAtomic` in hadrian and change all
invocations of shake non-atomic `writeFile'` to use `writeFileAtomic`,
to avoid multiple hadrian concurrent invocations overwriting the same
in-tree generated file not in the build root directory. Fixes #27536.
Additional notes:
- `writeFileChanged`/`writeFileChangedBS` cannot be made atomic since
it involves reading the file's older version, so their uses are left
alone. It doesn't affect #27536 given their outputs are contained in
the build root directory.
- It's possible to shrink this patch by only making writes outside the
build root directory atomic. But I think it's not worth the effort
for fine grained distinction here, and atomic writes within the
build root directory should also improve robustness of a hadrian
build.
- In the longer term we do want to make a ghc build only generate
files within the build root directory, though that's a lot of work
and outside the scope of this particular bugfix.
