It turns out that gmp 6.2.1 uses the platform-reserved `x18` register on
AArch64/Darwin. This was fixed in upstream changeset 18164:5f32dbc41afc,
which was merged in 2020. Here I backport this patch although I do hope
that a new release is forthcoming soon.
Bumps gmp-tarballs submodule.
Fixes #22497.

We need to ensure that the output of `cvtSigTypeKind` is parenthesized (at
precedence `sigPrec`) so that any type signatures with an outermost, explicit
kind signature can parse correctly.
Fixes #22784.

Following the plan in GHC Proposal #143 "Remove the * kind syntax",
which states:
In the next release (or 3 years in), enable -fwarn-star-is-type by default.
The "next release" happens to be 9.6.1
I also moved the T21583 test case from should_fail to should_compile,
because the only reason it was failing was -Werror=compat in our test
suite configuration.

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

In #22739 @AndreasK noticed that assertM performed the action to compute
the asserted predicate regardless of whether DEBUG is enabled. This is
inconsistent with the other assertion operations and general convention.

1. A python script in .gitlab/rel_eng/mk-ghcup-metadata which generates
suitable metadata for consumption by GHCUp for the relevant
pipelines.
- The script generates the metadata just as the ghcup maintainers
want, without taking into account platform/library combinations. It
is updated manually when the mapping changes.
- The script downloads the bindists which ghcup wants to distribute,
calculates the hash and generates the yaml in the correct structure.
- The script is documented in the .gitlab/rel_eng/mk-ghcup-metadata/README.mk file
1a. The script requires us to understand the mapping from platform ->
job. To choose the preferred bindist for each platform the
.gitlab/gen_ci.hs script is modified to allow outputting a metadata
file which answers the question about which job produces the
bindist which we want to distribute to users for a specific
platform.
2. Pipelines to run on nightly and release jobs to generate metadata
- ghcup-metadata-nightly: Generates metadata which points directly to
artifacts in the nightly job.
- ghcup-metadata-release: Generates metadata suitable for inclusion
directly in ghcup by pointing to the downloads folder where the
bindist will be uploaded to.
2a. Trigger jobs which test the generated metadata in the downstream
`ghccup-ci` repo. See that repo for documentation about what is
tested and how but essentially we test in a variety of clean images
that ghcup can download and install the bindists we say exist in our
metadata.
|
|
|
|
|
|
| |
This job exists only for the meta-reason of not allowing nightly
pipelines to be cancelled. It was taking two minutes to run as in order
to run "true" we would also clone the whole GHC repo.

It is better to keep these scripts in the tree as they depend on the CI
configuration and so on. By keeping them in tree we can keep them
up-to-date as the CI config changes and also makes it easier to backport
changes to the release script between release branches in future.
The final motivation is that it makes generating GHCUp metadata
possible.

Having the same CACHE_REV on both branches leads to issues where the
darwin toolchain is different on ghc-9.6 and HEAD which leads to long
darwin build times.
In general we should ensure that each branch has a different CACHE_REV.

The RHS was too large to inline which often prevented the overhead of the Maybe
from being optimized away. By marking it as INLINE we can eliminate the
overhead of both the maybe and are able to unpack the accumulator when
possible.

This patch introduces a more general version of &%> that works
with general traversable shapes, instead of lists. This allows us
to pass along the information that the length of the list of filepaths
passed to the function exactly matches the length of the input list
of filepath patterns, avoiding pattern match warnings.

This removes the wasm release jobs, as we do not yet intend to
distribute these binaries.
|
|
|
|
|

- There is one regular wasm job run in validate pipelines
- Additionally, int-native/unreg wasm jobs run in nightly/release pipelines
Also, remove the legacy handwritten wasm ci jobs in .gitlab-ci.yml.

- Add a ghc environment including prebuilt dependencies to the
nix-shell. Get rid of the ad hoc cabal cache and all dependencies
are now downloaded from the nixos binary cache.
- Make gen_ci.hs a cabal package with HLS integration, to make future
hacking of gen_ci.hs easier.
- Fix some ghc/hlint warnings after I got HLS to work.
- For the lint-ci-config job, do a shallow clone to save a few minutes
of unnecessary git checkout time.

When performing GC without work stealing there was no guarantee that
spark pruning was happening after marking of the sparks. This could

Many functions now return a `TailUsageDetails` that adorns a `UsageDetails` with
a `JoinArity` that reflects the number of join point binders around the body
for which the `UsageDetails` was computed. `TailUsageDetails` is now returned by
`occAnalLamTail` as well as `occAnalUnfolding` and `occAnalRules`.
I adjusted `Note [Join points and unfoldings/rules]` and
`Note [Adjusting right-hand sides]` to account for the new machinery.
I also wrote a new `Note [Join arity prediction based on joinRhsArity]`
and refer to it when we combine `TailUsageDetails` for a recursive RHS.
I also renamed
* `occAnalLam` to `occAnalLamTail`
* `adjustRhsUsage` to `adjustTailUsage`
* a few other less important functions
and properly documented the that each call of `occAnalLamTail` must pair up with
`adjustTailUsage`.
I removed `Note [Unfoldings and join points]` because it was redundant with
`Note [Occurrences in stable unfoldings]`.
While in town, I refactored `mkLoopBreakerNodes` so that it returns a condensed
`NodeDetails` called `SimpleNodeDetails`.
Fixes #22428.

As #22725 shows, in worker/wrapper we must add the void argument
/last/, not first. See GHC.Core.Opt.WorkWrap.Utils
Note [Worker/wrapper needs to add void arg last].
That led me to to study GHC.Core.Opt.SpecConstr
Note [SpecConstr needs to add void args first] which suggests the
opposite! And indeed I think it's the other way round for SpecConstr
-- or more precisely the void arg must precede the "extra_bndrs".
That led me to some refactoring of GHC.Core.Opt.SpecConstr.calcSpecInfo.

This patch completely re-engineers how we deal with loopy superclass
dictionaries in instance declarations. It fixes #20666 and #19690
The highlights are
* Recognise that the loopy-superclass business should use precisely
the Paterson conditions. This is much much nicer. See
Note [Recursive superclasses] in GHC.Tc.TyCl.Instance
* With that in mind, define "Paterson-smaller" in
Note [Paterson conditions] in GHC.Tc.Validity, and the new
data type `PatersonSize` in GHC.Tc.Utils.TcType, along with
functions to compute and compare PatsonSizes
* Use the new PatersonSize stuff when solving superclass constraints
See Note [Solving superclass constraints] in GHC.Tc.TyCl.Instance
* In GHC.Tc.Solver.Monad.lookupInInerts, add a missing call to
prohibitedSuperClassSolve. This was the original cause of #20666.
* Treat (TypeError "stuff") as having PatersonSize zero. See
Note [Paterson size for type family applications] in GHC.Tc.Utils.TcType.
* Treat the head of a Wanted quantified constraint in the same way
as the superclass of an instance decl; this is what fixes #19690.
See GHC.Tc.Solver.Canonical Note [Solving a Wanted forall-constraint]
(Thanks to Matthew Craven for this insight.)
This entailed refactoring the GivenSc constructor of CtOrigin a bit,
to say whether it comes from an instance decl or quantified constraint.
* Some refactoring way in which redundant constraints are reported; we
don't want to complain about the extra, apparently-redundant
constraints that we must add to an instance decl because of the
loopy-superclass thing. I moved some work from GHC.Tc.Errors to
GHC.Tc.Solver.
* Add a new section to the user manual to describe the loopy
superclass issue and what rules it follows.
