See #22630 and !9552
This commit:
- splits req_smp into req_target_smp and req_ghc_smp
- changes the testsuite driver to calculate req_ghc_smp
- changes a handful of tests to use req_target_smp instead of req_smp
- changes a handful of tests to use req_host_smp when needed
The problem:
- the problem this solves is the ambiguity surrounding req_smp
- on master req_smp was used to express the constraint that the program
being compiled supports smp _and_ that the host RTS (i.e., the RTS used
to compile the program) supported smp. Normally that is fine, but in
cross compilation this is not always the case as was discovered in #22630.
The solution:
- Differentiate the two constraints:
- use req_target_smp to say the RTS the compiled program is linked
with (and the platform) supports smp
- use req_host_smp to say the RTS the host is linked with supports smp
WIP: fix req_smp (target vs ghc)
add flag to separate bootstrapper
split req_smp -> req_target_smp and req_ghc_smp
update tests smp flags
cleanup and add some docstrings
only set ghc_with_smp to bootstrapper on S1 or CC
Only set ghc_with_smp to bootstrapperWithSMP of when testing stage 1
and cross compiling
test the RTS in config/ghc not hadrian
re-add ghc_with_smp
fix and align req names
fix T11760 to use req_host_smp
test the rts directly, avoid python 3.5 limitation
test the compiler in a try block
align out of tree and in tree withSMP flags
mark failing tests as host req smp
testsuite: req_host_smp --> req_ghc_smp
Fix ghc vs host, fix ghc_with_smp leftover

This adds support for calling Cmm code from bytecode using the native
calling convention, allowing modules that use `foreign import prim`
to be loaded and debugged in GHCi.
This patch introduces a new `PRIMCALL` bytecode instruction and
a helper stack frame `stg_primcall`. The code is based on the
existing functionality for dealing with unboxed tuples in bytecode,
which has been generalised to handle arbitrary calls.

Currently it doesn't do much anything, we are just trying to introduce
it without breaking the build. Later, we will move functionality from
the top-level configure script over to it.
We need to bump Cabal for https://github.com/haskell/cabal/pull/8649; to
facilitate and existing hack of skipping some configure checks for the
RTS we now need to skip just *part* not *all* of the "post configure"
hook, as running the configure script (which we definitely want to do)
is also implemented as part of the "post configure" hook. But doing this
requires exposing functionality that wasn't exposed before.

In #22764 a user noticed that a program implementing a simple atomic
counter via an STRef regressed significantly due to the introduction of
necessary atomic operations in the MutVar# primops (#22468). This
regression was caused by a bug in the NCG, which emitted an unnecessary
MFENCE instruction for a release-ordered atomic write. MFENCE is rather
only needed to achieve sequentially consistent ordering.
Fixes #22764.

Problem: In 2463df2f, the Solo data constructor was renamed to MkSolo,
and Solo was turned into a pattern synonym for backwards compatibility.
Since pattern synonyms can not be promoted, the old code that pretty-printed
promoted single-element tuples started producing ill-typed code:
t :: Proxy ('Solo Int)
This fails with "Pattern synonym ‘Solo’ used as a type"
The solution is to track the distinction between type constructors and data
constructors more carefully when printing single-element tuples.

Currently the driver diagnostics don't give any indication about which unit they correspond to.
For example `-Wmissing-home-modules` can fire multiple times for each different home unit and gives no indication about which unit it's actually reporting about.
Perhaps a longer term fix is to generalise the providence information away from a SrcSpan so that these kind of whole project errors can be reported with an accurate provenance. For now we can just include the `UnitId` in the error message.

Multiple units can refer to the same files without any problem. Just
another assumption which needs to be updated when we may have multiple
home units.
However, there is the invariant that within each unit each file only
maps to one module, so as long as we also key the cache by UnitId then
we are all good.
This led to some confusing behaviour in GHCi when reloading,
multipleHomeUnits_shared distils the essence of what can go wrong.

In order to preserve existing behaviour it's important to look within the current component before consideirng a module might come from an external component.
This already happened by accident in `downsweep`, (because roots are used to repopulated the cache) but in the `Finder` the logic was the wrong way around.

Lint was checking for duplicate external names by calling removeDups,
which needs a comparison function that is passed to Data.List.sortBy.
But the comparison was not a valid ordering - it returned LT
if one of the names was not external.
For example, the previous implementation won't find a duplicate in
[M.x, y, M.x].
Instead, we filter out non-external names before looking for duplicates.

We used to print the offset value to a platform word sized integer.
This is incorrect when the offset is negative (e.g. output of cmm
constant folding) and the register is 64-bit but on a 32-bit target,
and may lead to incorrect runtime result (e.g. #22607).
The fix is simple: just treat it as a proper MO_Add, with the correct
width info inferred from the register itself.

The HLint jobs takes much longer to run (20 minutes) after "Give the RTS it's own configure script" eb5a6b91
Now the CI job will build the stage0 compiler before it generates the necessary RTS headers.
We either need to:
* Fix the linting rules so they take much less time
* Revert the commit
* Remove the linting of base from the hlint job
* Remove the hlint job
This is highest priority as it is affecting all CI pipelines.
For now I am just disabling the job because there are many more pressing
matters at hand.

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

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

Previously, when using `capi` calling convention in foreign declarations,
code generator failed to handle const-cualified pointer return types.
This resulted in CC toolchain throwing `-Wincompatible-pointer-types-discards-qualifiers`
warning.
`Foreign.C.Types.ConstPtr` newtype was introduced to handle these cases -
special treatment was put in place to generate appropritetly qualified C
wrapper that no longer triggers the above mentioned warning.
Fixes #22043.

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

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

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

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

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

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

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

This patch tracks the type of Cmm global registers. This is needed
in order to lint uses of polymorphic registers, such as SIMD vector
registers that can be used both for floating-point and integer values.
This changes allows us to refactor VanillaReg to not store VGcPtr,
as that information is instead stored in the type of the usage of the
register.

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

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

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

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

The clang based toolchain uses ucrt as its math library
and so mingwex is no longer needed. In fact using mingwex
will cause incompatibilities as the default routines in both
have differing ULPs and string formatting modifiers.

During interactive linking, GHCi couldn't find the following symbol:

This may be due to you not asking GHCi to load extra object files,
archives or DLLs needed by your current session. Restart GHCi, specifying
the missing library using the -L/path/to/object/dir and -lmissinglibname
flags, or simply by naming the relevant files on the GHCi command line.
Alternatively, this link failure might indicate a bug in GHCi.
If you suspect the latter, please report this as a GHC bug:

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

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

Type variables from class/instance headers scope over class/instance
method type signatures, but DO NOT scope over the type signatures in
SPECIALISE and SPECIALISE instance pragmas.
The logic in GHC.Rename.Bind.rnMethodBinds correctly accounted for
SPECIALISE inline pragmas, but forgot to apply the same treatment
to method SPECIALISE pragmas, which lead to a Core Lint failure with
an out-of-scope type variable. This patch makes sure we apply the same
logic for both cases.

This reverts commit caced75765472a1a94453f2e5a439dba0d04a265.
It seems the patch "Don't keep exit join points so much" is causing
wide-spread regressions in the bytestring library benchmarks. If I
revert it then the 9.6 numbers are better on average than 9.4.

The testsuite driver used to create one thread per test case, and
explicitly use semaphore and locks for rate limiting and
synchronization. This is a bad practice in any language, and
occasionally may result in livelock conditions (e.g. #22889). This
patch uses concurrent.futures.ThreadPoolExecutor for scheduling test
case runs, which is simpler and more robust.

The core change in this commit, which fixes #22761, is that
* In a Core rule, ru_rhs is always occ-analysed.
This means adding a couple of calls to occurAnalyseExpr when
building a Rule, in
* GHC.Core.Rules.mkRule
* GHC.Core.Opt.Simplify.Iteration.simplRules
But diagosing the bug made me stare carefully at the code of the
Simplifier, and I ended up doing some only-loosely-related refactoring.
* I think that RULES could be lost because not every code path
did addBndrRules
* The code around lambdas was very convoluted
It's mainly moving deck chairs around, but I like it more now.

1. Hint address to NetBSD mmap(2) has a different semantics from that of
Linux. When a hint address is provided, mmap(2) searches for a free
region at or below the hint but *never* above it. This means we can't
reliably search for free regions incrementally on the userland,
especially when ASLR is enabled. Let the kernel do it for us if we don't
care where the mapped address is going to be.
2. NetBSD not only hates to map pages as rwx, but also disallows to switch
pages from rw- to r-x unless the intention is declared when pages are
initially requested. This means we need a new MemoryAccess mode for
pages that are going to be changed to r-x.

Commit aed1974e completely re-engineered the treatment of loopy
superclass dictionaries in instance declarations. Unfortunately,
it has the potential to break (albeit in a rather minor way) user code.
To alleviate migration concerns, this commit re-introduces the old
behaviour. Any reliance on this old behaviour triggers a warning,
controlled by `-Wloopy-superclass-solve`. The warning text explains
that GHC might produce bottoming evidence, and provides a migration
strategy.
This allows us to provide a graceful migration period, alerting users
when they are relying on this unsound behaviour.

The MBLOCK_SHIFT macro must be the single source of truth for defining
the mblock size, and changing it should only affect performance, not
correctness. This patch makes it truly possible to reconfigure mblock
size, at least on 32-bit targets, by fixing places which implicitly
relied on the previous MBLOCK_SHIFT constant. Fixes #22901.

generateCgIPEStub already correctly implements the CmmTick finding

switches based on whether the codegen is unregisterised, but there do
exist registerised builds that disable tables-next-to-code! This patch
corrects that problem. Fixes #22896.

We went to and fro on the solution, as you can see in #22924.
The result is carefully documented in
Note [Decomoposing newtype equalities]
On the way I had revert most of
commit 3e827c3f74ef76d90d79ab6c4e71aa954a1a6b90

Do newtype unwrapping in the canonicaliser and rewriter
See Note [Unwrap newtypes first], which has the details.
It turns out that
(a) 3e827c3f makes GHC behave worse on some recursive newtypes
(see one of the tests on this commit)
(b) the finer-grained test (namely noGivenNewtypeReprEqs) renders
3e827c3f unnecessary

Commit cfc8e2e2 introduced a mechanism for handling of exceptions
that occur during Handle finalization, and 372cf730 set the default
handler to print out the error to stderr.
However, #21680 pointed out we might not want to set this by default,
as it might pollute users' terminals with unwanted information.
So, for the time being, the default handler discards the exception.

`libiserv` serves no purpose. As it depends on `ghci` and doesn't have
more dependencies than the `ghci` package, its code could live in the

This commit also moves most of the code from the `iserv` program into
the `ghci` package as well so that it can be reused. This is especially
useful for the implementation of TH for the JS backend (#22261, !9779).

The wasm NCG used to map CCCS to a wasm global, based on the
observation that CCCS is a transient register that's already handled
by thread state load/store logic, so it doesn't need to be backed by
the rCCCS field in the register table.
Unfortunately, this is wrong, since even when Cmm execution hasn't
yielded back to the scheduler, the Cmm code may call enterFunCCS,
which does use rCCCS.
This breaks cost centre profiling in a subtle way, resulting in
inaccurate stack traces in some test cases. The fix is simple though:
just remove the CCCS mapping.

Data constructor wrappers only make sense for _value_-level data constructors,
but data constructors for `type data` declarations only exist at the _type_
level. This patch does the following:
* The criteria in `GHC.Types.Id.Make.mkDataConRep` for whether a data
constructor receives a wrapper now consider whether or not its parent data
type was declared with `type data`, omitting a wrapper if this is the case.
* Now that `type data` data constructors no longer receive wrappers, there is a
spot of code in `refineDefaultAlt` that panics when it encounters a value
headed by a `type data` type constructor. I've fixed this with a special case
in `refineDefaultAlt` and expanded `Note [Refine DEFAULT case alternatives]`
to explain why we do this.

This patch implements GHC proposal 496, which allows record wildcards
to be used for nullary constructors, e.g.
data A = MkA1 | MkA2 { fld1 :: Int }
f :: A -> Int
f (MkA1 {..}) = 0
f (MkA2 {..}) = fld1
To achieve this, we add arity information to the record field
environment, so that we can accept a constructor which has no fields
while continuing to reject non-record constructors with more than 1
field. See Note [Nullary constructors and empty record wildcards],
as well as the more general overview in Note [Local constructor info in the renamer],
both in the newly introduced GHC.Types.ConInfo module.

This patch makes it so vars from one block of a parallel list

of scope variable shared the occ name of a var from a different block.
