A declaration such as infixr ++++ is supplied with an implicit fixity of 9 in the parser, but uses an invalid SrcSpan to capture this. Use of this span triggers a panic. Fix the problem by not recording an exact print annotation for the non-existent fixity source. Closes #20846

I made a mistake in the bash script so there were errors about "$CI_MERGE_REQUEST_DIFF_BASE_SHA" not existing.

OpenBSD doesn't have this library and so the linker complains: ld.lld: error: unable to find library -ldl
-
This is not entirely accurate because some openbsd architectures use gcc. Yet we don't have ghc ported to them and thus the approximation is good enough. Fixes ghcilink006 test
-
Plugins were directly fetched from HscEnv (hsc_static_plugins and hsc_plugins). The tight coupling of plugins and of HscEnv is undesirable and it's better to store them in a new Plugins datatype and to use it in the plugins' API (e.g. withPlugins, mapPlugins...). In the process, the interactive context (used by GHCi) got proper support for different static plugins than those used for loaded modules. Bump haddock submodule

As suggested in #20601, this is a short-hand for enabling the usual GHC-internal sanity checks one typically leans on when debugging runtime crashes.
-
As noted in #20601, the previous name was rather misleading.

Here we introduce code generator support for instrument array primops with bounds checking, enabled with the `-fcheck-prim-bounds` flag. Introduced to debug #20769.

This place ensures that the default -dcore-lint option is disabled by default when collect_compiler_stats is used but you can still pass -dcore-lint as an additional option (see T1969 which tests core lint performance).

Fixes #20827 by filtering out any default free variable demands (as per `defaultFvDmd`) prior to comparing the assocs of the `DmdEnv`. The details are in `Note [Demand type Equality]`.

With this patch, withBinBuffer will construct a ByteString that properly captures the reference to the BinHandle internal MutableByteArray#, making it safe to convert a BinHandle to ByteString and use that ByteString outside the continuation.

It turns out there was already a function in the CI script to correctly set the baseline for performance tests but it was just never called. I now call it during the initialisation to set the correct baseline. I also made the make testsuite driver take into account the PERF_BASELINE_COMMIT environment variable Fixes #20811

As noted in #20763 the way the stats were printed was quite hard for a human to compare. Therefore we now insert the comma separator so that they are easier to compare at a glance.

isUnliftedTyCon was used in three places: Ticky, Template Haskell and FFI checks. It was straightforward to remove it from Ticky and Template Haskell. It is now used in FFI only and renamed to marshalablePrimTyCon. Previously, it was fetching information from a field in PrimTyCon called is_unlifted. Instead, I've changed the code to compute liftedness based on the kind. isFFITy and legalFFITyCon are removed. They were only referred from an old comment that I removed. There were three functions to define a PrimTyCon, but the only difference was that they were setting is_unlifted to True or False. Everything is now done in mkPrimTyCon. I also added missing integer types in Ticky.hs, I think it was an oversight. Fixes #20401

We used to attempt compiling `foo_t val; *val;` to determine if `foo_t` is a pointer type in C. This doesn't work if `foo_t` points to an incomplete type, and autoconf will detect `foo_t` as a floating point type in that case. Now we use `memset(val, 0, 0)` instead, and it works for incomplete types as well.
-
When autoconf detects a C pointer type, we used to specify `Ptr ()` as the Haskell type. This doesn't work in some cases, e.g. in `wasi-libc`, `clockid_t` is a pointer type, but we expected `CClockId` to be an integral type, and `Ptr ()` lacks various integral type instances.

This adds a new mode, `--merge-objs`, which can be used to produce merged GHCi library objects. As future work we will rip out the object-merging logic in Hadrian and Cabal and instead use this mode. Closes #20712.

This flag was previously called `--mk-dll`. It was renamed to `-shared` in b562cbe3 but the documentation wasn't updated to match.
