Fix VoidRep handling in ghci debugger
'go' inside extractSubTerms was giving a bad result given a VoidRep,
attempting to round towards the next multiple of 0.
I don't understand much about the debugger but the code should be better
than it was.
Fixes #24306

VoidRep-related refactor
* In GHC.StgToByteCode, replace bcIdPrimId with idPrimRep,
bcIdArgRep with idArgRep, atomPrimRep with stgArgRep1.
All of them were duplicates.
* In GHC.Stg.Unarise, we were converting a PrimRep to a Type and back to
PrimRep. Remove the calls to primRepToType and typePrimRep1 which cancel out.
* In GHC.STG.Lint, GHC.StgToCmm, GHC.Types.RepType we were filtering out
VoidRep from the result of typePrimRep. But typePrimRep never returns
VoidRep - remove the filtering.

Remove VoidRep from PrimRep, introduce PrimOrVoidRep
This introduces
data PrimOrVoidRep = VoidRep | NVRep PrimRep
changes typePrimRep1 to return PrimOrVoidRep, and adds a new function
typePrimRepU to be used when the argument is definitely non-void.

Deprecate -Wsemigroup
This warning was used to prepare for Semigroup becoming a superclass
of Monoid, and for (<>) being exported from Prelude. This happened in
GHC 8.4 in 8ae263ceb3566 and feac0a3bc69fd3.
The leftover logic for (<>) has been removed in GHC 9.8, 4d29ecdfcc79.
Now the warning does nothing at all and can be deprecated.

driver: Set -DPROFILING when compiling C++ sources with profiling
Earlier, we used to pass all preprocessor flags to the c++ compiler.
This meant that -DPROFILING was passed to the c++ compiler because
it was a part of C++ flags
However, this was incorrect and the behaviour was changed in
8ff3134ed4aa323b0199ad683f72165e51a59ab6. See #21291.
But that commit exposed this bug where -DPROFILING was no longer being passed
when compiling c++ sources.
The fix is to explicitly include -DPROFILING in `opt_cxx` when profiling is
enabled to ensure we pass the correct options for the way to both C and C++
compilers
Fixes #24286

Arity: Require called *exactly once* for eta exp with -fpedantic-bottoms (#24296)
In #24296, we had a program in which we eta expanded away an error despite the
presence of `-fpedantic-bottoms`.
This was caused by turning called *at least once* lambdas into one-shot lambdas,
while with `-fpedantic-bottoms` it is only sound to eta expand over lambdas that
are called *exactly* once.
An example can be found in `Note [Combining arity type with demand info]`.
Fixes #24296.

When looking up a value, we want to be able to find both variables

a record field with the given textual name will belong to.

Make the build more strict on documentation errors
* Detect undefined labels. This can be tested by adding :ref:`nonexistent`
to a documentation rst file; attempting to build docs will fail.
Fixed the undefined label in `9.8.1-notes.rst`.
* Detect errors. While we have plenty of warnings, we can at least enforce
that Sphinx does not report errors.
Fixed the error in `required_type_arguments.rst`.
Unrelated change: I have documented that the `-dlint` enables
`-fcatch-nonexhaustive-cases`, as can be verified by checking
`enableDLint`.

Profiling: Adds an option to not start time profiling at startup
Using the functionality provided by
d89deeba47ce04a5198a71fa4cbc203fe2c90794, this patch creates a new rts
flag `--no-automatic-time-samples` which disables the time profiling
when starting a program. It is then expected that the user starts it
whenever it is needed.

eventlog: Fix off-by-one error in postIPE
We were missing the extra_comma from the calculation of the size of the
payload of postIPE. This was causing assertion failures when the event
would overflow the buffer by one byte, as ensureRoomForVariable event
would report there was enough space for `n` bytes but then we would
write `n + 1` bytes into the buffer.

Improve SpecConstr (esp nofib/spectral/ansi)
This MR makes three improvements to SpecConstr: see #24282
* It fixes an outright (and recently-introduced) bug in `betterPat`, which
was wrongly forgetting to compare the lengths of the argument lists.
* It enhances ConVal to inclue a boolean for work-free-ness, so that the
envt can contain non-work-free constructor applications, so that we
can do more: see Note [ConVal work-free-ness]
* It rejigs `subsumePats` so that it doesn't reverse the list. This can
make a difference because, when patterns overlap, we arbitrarily pick
the first. There is no "right" way, but this retains the old
pre-subsumePats behaviour, thereby "fixing" the regression in #24282.
Nofib results
+========================================
| spectral/ansi -21.14%
| spectral/hartel/comp_lab_zift -0.12%
| spectral/hartel/parstof +0.09%
| spectral/last-piece -2.32%
| spectral/multiplier +6.03%
| spectral/para +0.60%
| spectral/simple -0.26%
+========================================
| geom mean -0.18%
+----------------------------------------
The regression in `multiplier` is sad, but it simply replicates GHC's
previous behaviour (e.g. GHC 9.6).

hadrian: Reduce Cabal verbosity
The comment claims that `simpleUserHooks` decrease verbosity, and it
does, but only for the `postConf` phase. The other phases are too
verbose with `-V`.
At the moment > 5000 lines of the build log are devoted to output from
`cabal copy`.
So I take the simple approach and just decrease the verbosity level
again.
If the output of `postConf` is essential then it would be better to
implement our own `UserHooks` which doesn't decrease the verbosity for
`postConf`.
Fixes #24338

Stop retaining old ModGuts throughout subsequent simplifier phases
Each phase of the simplifier typically rewrites the majority of ModGuts,
so we want to be able to release the old ModGuts as soon as possible.
`name_ppr_ctxt` lives throught the whole optimiser phase and it was
retaining a reference to `ModGuts`, so we were failing to release the
old `ModGuts` until the end of the phase (potentially doubling peak
memory usage for that particular phase).
This was discovered using eras profiling (#24332)

base: treat all FDs as "nonblocking" on wasm
On posix platforms, when performing read/write on FDs, we check the
nonblocking flag first. For FDs without this flag (e.g. stdout), we
call fdReady() first, which in turn calls poll() to wait for I/O to be
available on that FD. This is problematic for wasm32-wasi: although
select()/poll() is supported via the poll_oneoff() wasi syscall, that
syscall is rather heavyweight and runtime behavior differs in
different wasi implementations. The issue is even worse when targeting
browsers, given there's no satisfactory way to implement async I/O as
a synchronous syscall, so existing JS polyfills for wasi often give up
and simply return ENOSYS.
Before we have a proper I/O manager that avoids poll_oneoff() for
async I/O on wasm, this patch improves the status quo a lot by merely
pretending all FDs are "nonblocking". Read/write on FDs will directly
invoke read()/write(), which are much more reliably handled in
existing wasi implementations, especially those in browsers.
Fixes #23275 and the following test cases: T7773 isEOF001 openFile009

- the instruction name is "llvm.fma.f32" or "llvm.fma.f64", not "fmadd"

we implement these by flipping signs of some arguments

Fix irrelevant dodgy-foreign-imports warning on import f-pointers by value
A test *сс018* is attached (not sure about the naming convention though).
Note that without the fix, the test fails with the *dodgy-foreign-imports*
warning passed to stderr. The warning disappears after the fix.
GHC shouldn't warn on imports of natural function pointers from C by value
(which is feasible with CApiFFI), such as
```haskell
foreign import capi "cc018.h value f" f :: FunPtr (Int -> IO ())
```
where
```c
void (*f)(int);
```
See a related real-world use-case
[here](https://gitlab.com/daniel-casanueva/pcre-light/-/merge_requests/17).
There, GHC warns on import of C function pointer `pcre_free`.

from memory deep within an expression (e.g. see the `CHECK_GC` macro).
This MachOp provides a convenient way to do so without breaking the
expression into multiple statements.

Namespacing for WARNING/DEPRECATED pragmas (#24396)
New syntax for WARNING and DEPRECATED pragmas was added,
namely namespace specifierss:
namespace_spec ::= 'type' | 'data' | {- empty -}
warning ::= warning_category namespace_spec namelist strings
deprecation ::= namespace_spec namelist strings
A new data type was introduced to represent these namespace specifiers:
data NamespaceSpecifier =
NoSpecifier |
TypeNamespaceSpecifier (EpToken "type") |
DataNamespaceSpecifier (EpToken "data")
Extension field XWarning now contains this NamespaceSpecifier.
lookupBindGroupOcc function was changed: it now takes NamespaceSpecifier
and checks that the namespace of the found names matches the passed flag.
With this change {-# WARNING data D "..." #-} pragma will only affect value
namespace and {-# WARNING type D "..." #-} will only affect type
namespace. The same logic is applicable to DEPRECATED pragmas.
Finding duplicated warnings inside rnSrcWarnDecls now takes into
consideration NamespaceSpecifier flag to allow warnings with the
same names that refer to different namespaces.

Bump bytestring submodule to something closer to 0.12.1
...mostly so that 16d6b7e835ffdcf9b894e79f933dd52348dedd0c
(which reworks unaligned writes in Builder) and the stuff in
https://github.com/haskell/bytestring/pull/631 can see wider testing.
The less-terrible code for unaligned writes used in Builder on
hosts not known to be ulaigned-friendly also takes less effort
for GHC to compile, resulting in a metric decrease for T21839c
on some platforms.
The metric increase on T21839r is caused by the unrelated commit
750dac33465e7b59100698a330b44de7049a345c. It perhaps warrants
further analysis and discussion (see #23822) but is not critical.

and $CXX variables, which we traditionally assume to be just the

Expand `do` blocks right before typechecking using the `HsExpansion` philosophy.
- Fixes #18324 #20020 #23147 #22788 #15598 #22086 #21206
- The change is detailed in
- Note [Expanding HsDo with HsExpansion] in `GHC.Tc.Gen.Do`
- Note [Doing HsExpansion in the Renamer vs Typechecker] in `GHC.Rename.Expr`
expains the rational of doing expansions in type checker as opposed to in the renamer
- Adds new datatypes:
- `GHC.Hs.Expr.XXExprGhcRn`: new datatype makes this expansion work easier
1. Expansion bits for Expressions, Statements and Patterns in (`ExpandedThingRn`)
2. `PopErrCtxt` a special GhcRn Phase only artifcat to pop the previous error message in the error context stack
- `GHC.Basic.Origin` now tracks the reason for expansion in case of Generated
This is useful for type checking cf. `GHC.Tc.Gen.Expr.tcExpr` case for `HsLam`
- Kills `HsExpansion` and `HsExpanded` as we have inlined them in `XXExprGhcRn` and `XXExprGhcTc`
- Ensures warnings such as
1. Pattern match checks
2. Failable patterns
3. non-() return in body statements are preserved
- Kill `HsMatchCtxt` in favor of `TcMatchAltChecker`
- Testcases:
* T18324 T20020 T23147 T22788 T15598 T22086
* T23147b (error message check),
* DoubleMatch (match inside a match for pmc check)
* pattern-fails (check pattern match with non-refutable pattern, eg. newtype)
* Simple-rec (rec statements inside do statment)
* T22788 (code snippet from #22788)
* DoExpanion1 (Error messages for body statments)
* DoExpansion2 (Error messages for bind statements)
* DoExpansion3 (Error messages for let statements)
Also repoint haddock to the right submodule so that the test (haddockHypsrcTest) pass
Metric Increase 'compile_time/bytes allocated':
T9020
The testcase is a pathalogical example of a `do`-block with many statements that do nothing.
Given that we are expanding the statements into function binds, we will have to bear
a (small) 2% cost upfront in the compiler to unroll the statements.

a complete user-supplied signature) is its own data type.
- Split TcIdSigInfo(CompleteSig, PartialSig) into
TcCompleteSig(CSig)
TcPartialSig(PSig)
- Use TcCompleteSig in tcPolyCheck, CheckGen

- Shuffle around helper functions:
tcSigInfoName (moved to GHC.Tc.Types.BasicTypes)
completeSigPolyId_maybe (moved to GHC.Tc.Types.BasicTypes)
tcIdSigName (inlined and removed)
tcIdSigLoc (introduced)

Lazy skolemisation for @a-binders (#17594)
This patch is a preparation for @a-binders implementation. The main changes are:

- Utils.Unify.matchExpectedFunTys
- Gen.Pat.tcMatchPats
- Gen.Expr.tcPolyExprCheck
- Gen.Binds.tcPolyCheck
Some accompanying refactoring:
* I found that funTyConAppTy_maybe was doing a lot of allocation, and

driver: Really don't lose track of nodes when we fail to resolve cycles
This fixes a bug in 8db8d2fd1c881032b1b360c032b6d9d072c11723, where we could lose
track of acyclic components at the start of an unresolved cycle. We now ensure we
never loose track of any of these components.
As T24275 demonstrates, a "cyclic" SCC might not really be a true SCC:
When viewed without boot files, we have a single SCC
```
[REC main:T24275B [main:T24275B {-# SOURCE #-},
main:T24275A {-# SOURCE #-}]
main:T24275A [main:T24275A {-# SOURCE #-}]]
```
But with boot files this turns into
```
[NONREC main:T24275B {-# SOURCE #-} [],
REC main:T24275B [main:T24275B {-# SOURCE #-},
main:T24275A {-# SOURCE #-}]
main:T24275A {-# SOURCE #-} [main:T24275B],
NONREC main:T24275A [main:T24275A {-# SOURCE #-}]]
```
Note that this is truly not an SCC, as no nodes are reachable from T24275B.hs-boot.
However, we treat this entire group as a single "SCC" because it seems so when we
analyse the graph without taking boot files into account.
Indeed, we must return a single ResolvedCycle element in the BuildPlan for this
as described in Note [Upsweep].
However, since after resolving this is not a true SCC anymore, `findCycle` fails
to find a cycle and we have a sub-optimal error message as a result.
To handle this, I extended `findCycle` to not assume its input is an SCC, and to
try harder to find cycles in its input.

ts: add compile_artifact, ignore_extension flag
In b521354216f2821e00d75f088d74081d8b236810 the testsuite gained the
capability to collect generic metrics. But this assumed that the test
was not linking and producing artifacts and we only wanted to track
object files, interface files, or build artifacts from the compiler
build. However, some backends, such as the JS backend, produce artifacts when
compiling, such as the jsexe directory which we want to track.
This patch:
- tweaks the testsuite to collect generic metrics on any build artifact
in the test directory.
- expands the exe_extension function to consider windows and adds the
ignore_extension flag.
- Modifies certain tests to add the ignore_extension flag. Tests such as
heaprof002 expect a .ps file, but on windows without ignore_extensions
the testsuite will look for foo.exe.ps. Hence the flag.
- adds the size_hello_artifact test

This logic appears to be incorrect as it would drop any dependency which
was not in a direct dependency of the package being linked.
In the ghc-internals split this started to cause errors because
`ghc-internal` is not a direct dependency of most packages, and hence
important symbols to keep which are hard coded into the js runtime were
getting dropped.

44f6557a by Ben Gamari at 2024-02-08T00:35:59-05:00
Move `base` to `ghc-internal`
Here we move a good deal of the implementation of `base` into a new
package, `ghc-internal` such that it can be evolved independently
from the user-visible interfaces of `base`.
While we want to isolate implementation from interfaces, naturally, we
would like to avoid turning `base` into a mere set of module re-exports.
However, this is a non-trivial undertaking for a variety of reasons:
* `base` contains numerous known-key and wired-in things, requiring
corresponding changes in the compiler
* `base` contains a significant amount of C code and corresponding
autoconf logic, which is very fragile and difficult to break apart
* `base` has numerous import cycles, which are currently dealt with via
carefully balanced `hs-boot` files
* We must not break existing users
To accomplish this migration, I tried the following approaches:
* [Split-GHC.Base]: Break apart the GHC.Base knot to allow incremental
migration of modules into ghc-internal: this knot is simply too
intertwined to be easily pulled apart, especially given the rather
tricky import cycles that it contains)
* [Move-Core]: Moving the "core" connected component of base (roughly
150 modules) into ghc-internal. While the Haskell side of this seems
tractable, the C dependencies are very subtle to break apart.
* [Move-Incrementally]:
1. Move all of base into ghc-internal
2. Examine the module structure and begin moving obvious modules (e.g.
leaves of the import graph) back into base
3. Examine the modules remaining in ghc-internal, refactor as necessary
to facilitate further moves
4. Go to (2) iterate until the cost/benefit of further moves is
insufficient to justify continuing
5. Rename the modules moved into ghc-internal to ensure that they don't
overlap with those in base
6. For each module moved into ghc-internal, add a shim module to base
with the declarations which should be exposed and any requisite
Haddocks (thus guaranteeing that base will be insulated from changes
in the export lists of modules in ghc-internal
Here I am using the [Move-Incrementally] approach, which is empirically
the least painful of the unpleasant options above

also can easily create this file.)

rts: eras profiling mode
The eras profiling mode is useful for tracking the life-time of
closures. When a closure is written, the current era is recorded in the
profiling header. This records the era in which the closure was created.
* Enable with -he
* User mode: Use functions ghc-experimental module GHC.Profiling.Eras to modify the era
* Automatically: --automatic-era-increment, increases the user era on major
collections
* The first era is era 1
* -he<era> can be used with other profiling modes to select a specific
era
If you just want to record the era but not to perform heap profiling you
can use `-he --no-automatic-heap-samples`.

JS: handle stored null StablePtr
Some Haskell codes unsafely cast StablePtr into ptr to compare against
NULL. E.g. in direct-sqlite:
if castStablePtrToPtr aggStPtr /= nullPtr then
where `aggStPtr` is read (`peek`) from zeroed memory initially.
We fix this by giving these StablePtr the same representation as other
null pointers. It's safe because StablePtr at offset 0 is unused (for
this exact reason).

JS: add support for linking C sources
Support linking C sources with JS output of the JavaScript backend.
See the added documentation in the users guide.
The implementation simply extends the JS linker to use the objects (.o)
that were already produced by the emcc compiler and which were filtered
out previously. I've also added some options to control the link with C
functions (see the documentation about pragmas).
With this change I've successfully compiled the direct-sqlite package
which embeds the sqlite.c database code. Some wrappers are still
required (see the documentation about wrappers) but everything generic
enough to be reused for other libraries have been integrated into
rts/js/mem.js.

nonmoving: Add support for heap profiling
Add support for heap profiling while using the nonmoving collector.
We greatly simply the implementation by disabling concurrent collection for
GCs when heap profiling is enabled. This entails that the marked objects on
the nonmoving heap are exactly the live objects.
Note that we match the behaviour for live bytes accounting by taking the size
of objects on the nonmoving heap to be that of the segment's block
rather than the object itself.

Parser, renamer, type checker for @a-binders (#17594)
GHC Proposal 448 introduces binders for invisible type arguments
(@a-binders) in various contexts. This patch implements @-binders
in lambda patterns and function equations:
{-# LANGUAGE TypeAbstractions #-}
id1 :: a -> a
id1 @t x = x :: t -- @t-binder on the LHS of a function equation
higherRank :: (forall a. (Num a, Bounded a) => a -> a) -> (Int8, Int16)
higherRank f = (f 42, f 42)
ex :: (Int8, Int16)
ex = higherRank (\ @a x -> maxBound @a - x )
-- @a-binder in a lambda pattern in an argument
-- to a higher-order function
Syntax
------
To represent those @-binders in the AST, the list of patterns in Match
now uses ArgPat instead of Pat:
data Match p body
= Match {
...
- m_pats :: [LPat p],
+ m_pats :: [LArgPat p],
...
}
+ data ArgPat pass
+ = VisPat (XVisPat pass) (LPat pass)
+ | InvisPat (XInvisPat pass) (HsTyPat (NoGhcTc pass))
+ | XArgPat !(XXArgPat pass)
The VisPat constructor represents patterns for visible arguments,
which include ordinary value-level arguments and required type arguments
(neither is prefixed with a @), while InvisPat represents invisible type
arguments (prefixed with a @).
Parser
------
In the grammar (Parser.y), the lambda and lambda-cases productions of
aexp non-terminal were updated to accept argpats instead of apats:
aexp : ...
- | '\\' apats '->' exp
+ | '\\' argpats '->' exp
...
- | '\\' 'lcases' altslist(apats)
+ | '\\' 'lcases' altslist(argpats)
...
+ argpat : apat
+ | PREFIX_AT atype
Function left-hand sides did not require any changes to the grammar, as
they were already parsed with productions capable of parsing @-binders.
Those binders were being rejected in post-processing (isFunLhs), and now
we accept them.
In Parser.PostProcess, patterns are constructed with the help of
PatBuilder, which is used as an intermediate data structure when
disambiguating between FunBind and PatBind. In this patch we define
ArgPatBuilder to accompany PatBuilder. ArgPatBuilder is a short-lived
data structure produced in isFunLhs and consumed in checkFunBind.
Renamer
-------
Renaming of @-binders builds upon prior work on type patterns,
implemented in 2afbddb0f24, which guarantees proper scoping and
shadowing behavior of bound type variables.
This patch merely defines rnLArgPatsAndThen to process a mix of visible
and invisible patterns:
+ rnLArgPatsAndThen :: NameMaker -> [LArgPat GhcPs] -> CpsRn [LArgPat GhcRn]
+ rnLArgPatsAndThen mk = mapM (wrapSrcSpanCps rnArgPatAndThen) where
+ rnArgPatAndThen (VisPat x p) = ... rnLPatAndThen ...
+ rnArgPatAndThen (InvisPat _ tp) = ... rnHsTyPat ...
Common logic between rnArgPats and rnPats is factored out into the
rn_pats_general helper.
Type checker
------------
Type-checking of @-binders builds upon prior work on lazy skolemisation,
implemented in f5d3e03c56f.
This patch extends tcMatchPats to handle @-binders. Now it takes and
returns a list of LArgPat rather than LPat:
tcMatchPats ::
...
- -> [LPat GhcRn]
+ -> [LArgPat GhcRn]
...
- -> TcM ([LPat GhcTc], a)
+ -> TcM ([LArgPat GhcTc], a)
Invisible binders in the Match are matched up with invisible (Specified)
foralls in the type. This is done with a new clause in the `loop` worker
of tcMatchPats:
loop :: [LArgPat GhcRn] -> [ExpPatType] -> TcM ([LArgPat GhcTc], a)
loop (L l apat : pats) (ExpForAllPatTy (Bndr tv vis) : pat_tys)
...
-- NEW CLAUSE:

hadrian: Generate HSC2HS_EXTRAS variable in bindist installation
We must generate the hsc2hs wrapper at bindist installation time since
it must contain `--lflag` and `--cflag` arguments which depend upon the
installation path.
The solution here is to substitute these variables in the configure
script (see mk/hsc2hs.in). This is then copied over a dummy wrapper in
the install rules.
Fixes #24050.

Namespacing for fixity signatures (#14032)
Namespace specifiers were added to syntax of fixity signatures:
- sigdecl ::= infix prec ops | ...
+ sigdecl ::= infix prec namespace_spec ops | ...
To preserve namespace during renaming MiniFixityEnv type
now has separate FastStringEnv fields for names that should be
on the term level and for name that should be on the type level.
makeMiniFixityEnv function was changed to fill MiniFixityEnv in the right way:
- signatures without namespace specifiers fill both fields
- signatures with 'data' specifier fill data field only
- signatures with 'type' specifier fill type field only
Was added helper function lookupMiniFixityEnv that takes care about
looking for a name in an appropriate namespace.
Updates haddock submodule.

rts: remove unused HAVE_C11_ATOMICS macro
This commit removes the unused HAVE_C11_ATOMICS macro. We used to have
a few places that have fallback paths when HAVE_C11_ATOMICS is not
defined, but that is completely redundant, since the
FP_CC_SUPPORTS__ATOMICS configure check will fail when the C compiler
doesn't support C11 style atomics. There are also many places (e.g. in
unreg backend, SMP.h, library cbits, etc) where we unconditionally use
C11 style atomics anyway which work in even CentOS 7 (gcc 4.8), the
oldest distro we test in our CI, so there's no value in keeping
HAVE_C11_ATOMICS.

Accept performance shifts from ghc-internal restructure
As expected, Haddock now does more work. Less expected is that some
other testcases actually get faster, presumably due to less interface
file loading. As well, the size_hello_artifact test regressed a bit when
debug information is enabled due to debug information for the new stub
symbols.

base: Explicit dependency to workaround #24436
Currently `ghc -M` fails to account for `.hs-boot` files correctly,
leading to issues with cross-package one-shot builds failing. This
currently manifests in `GHC.Exception` due to the boot file for
`GHC.Internal.Stack`. Work around this by adding an explicit `import`,
ensuring that `GHC.Internal.Stack` is built before `GHC.Exception`.
See #24436.
