This patch removes unused `USE_REPORT_PRELUDE` code paths from the

tree. They have been present since the first git revision

4fb94ae5e5d632748fa2e6c35e259eccc5a1a3f4, and might have been useful

for debugging purposes many years ago, but these code paths are never

actually built. Removing these ease maintenance of relevant modules in

the future, and also allows us to get rid of `CPP` extension in those

modules as a nice byproduct.

There are two parts to this commit.

* We moved the definition of BooleanFormula over to L.H.S.BooleanFormula

* We parameterized the BooleanFormula over the pass

The GHC specific details of BooleanFormula remain in Ghc.Data.BooleanFormula.

Because its parameterized over the pass its no longer a functor or

traversable, but we defined bfMap and bfTraverse for the cases where we

needed fmap and traverse originally. Most other changes are just churn.

Before this patch, some custom hacks were necessary in ghc-prim's

Setup.hs to register the GHC.Prim (virtual) module and in Hadrian to

generate haddocks properly.

In this patch we special-case this module in the compiler itself instead

(which it already is, see ghcPrimIface in GHC.Iface.Load). From

Cabal/Hadrian's perspective GHC.Prim is now just a normal autogenerated

module.

This simplification is worthwhile on its own. It was found while looking

into the work needed for #24453 which aims to merge ghc-prim,

ghc-bignum, and ghc-internal. It's also one step closer to remove

ghc-prim's custom setup.

Here we verify the previously informal invariant that stable release

version numbers must have three components, preventing costly failed

releases.

Specifically, the check fails in the following scenarios:

 * `version=9.13` while `RELEASE=YES` since this would imply a

   release made from an unstable branch

 * `version=9.13.0` since unstable versions should only have two

   components

 * `version=9.12` since this has the wrong number of version components

   for a stable branch

Fixes #25390.

When a testsuite linter is executed with the `tracked` strategy, the

driver runs `git ls-tree` to collect eligible files.

This appears to have ceased producing any paths – `ls-tree` restricts

its results to the current working directory, which is

`testsuite/tests/linters` in this case.

As a quick fix, this patch changes the working directory to match

expectations.

included in some boot packages were too old. As a mitigation for this,

we introduced logic in the `boot` script to update the `config.sub`

with that from the GHC tree. However, this causes submodules which

have `config.sub` committted to appear to be dirty. This is a

considerable headache.

Now since `config.sub` with full platform support is more common we can

remove `boot`'s `config.sub` logic.

Fixes #19574.

This patch improves the compile_flags.txt config used to power clangd

for the rts C codebase. The flags in the file are sampled & deduped

from a real stage1 build with clang-19 and vastly improves the IDE

accuracy when hacking the rts.

For maximum code coverage under the default settings,

compile_flags.txt defaults to threaded+profiled+dynamic+debug way.

This does not mean profdyn needs to be actually built in _build/stage1

for IDE to work. To activate IDE for other RTS ways, simply remove one

of the -D flags at the end of compile_flags.txt and restart clangd.

Basic changes:

* Change `catch` function to propagate exceptions using the

  WhileHandling mechanism.

* Introduce `catchNoPropagate`, which does the same as before, but

  passes an exception which can be rethrown.

* Introduce `rethrowIO` combinator, which rethrows an exception with a

  context and doesn't add a new backtrace.

* Introduce `tryWithContext` for a variant of `try` which can rethrow

  the exception with it's original context.

* onException is modified to rethrow the original error rather than

  creating a new callstack.

* Functions which rethrow in GHC.Internal.IO.Handle.FD,

  GHC.Internal.IO.Handle.Internals, GHC.Internal.IO.Handle.Text, and

  GHC.Internal.System.IO.Error are modified to not add a new callstack.

This commit changes the Exception instance of SomeException to *simply*

display the underlying exception in `displayException`. The augmented

exception message that included the type and backtrace of the exception

are now only printed on a call to `displayExceptionWithInfo`.

At a surface level, existing programs should behave the same since the

`uncaughtExceptionHandler`, which is responsible for printing out uncaught

exceptions to the user, will use `displayExceptionWithInfo` by default.

However, unlike the instance's `displayException` method, the

`uncaughtExceptionHandler` can be overriden with

`setUncaughtExceptionHandler`. This makes the extra information opt-in

without fixing it the instance, which can be valuable if your program

wants to display uncaught exceptions to users in a user-facing way

(ie without backtraces).

This is what was originally agreed for CLC#231 or CLC#261 with regard to

the type of the exception information.

The call stack also becoming part of the default handler rather than the

Exception instance is an ammendment to CLC#164.

Discussion of the ammendment is part of CLC#285.

accumulated its own callstack via HasCallStack constraints, but

re-defining displayExceptionContext.

When running the program with `runhaskell`/`runghc` the backtrace should

match the backtrace one would get by compiling and running the program.

But currently, an exception thrown in a program interpreted with

`runhaskell` will:

    * Not include the original exception backtrace at all

    * Include the backtrace from the internal GHCi/ghc rethrowing of the

      original exception

This commit fixes this divergence by not annotating the ghc(i) backtrace

(with NoBacktrace) and making sure that the backtrace of the original

exception is serialized across the boundary and rethrown with the

appropriate context.

Fixes #25116

The !13301 MR (not this commit in particular) improves performance of

MultiLayerModules. Unfortunately, T3294 regresses on aarch64-linux-deb12

by 1% allocations. Since this patch must be merged for 9.12 ASAP, we

will not be able to investigate the slight regression on this platform

in time.

Introduces `ReachabilityIndex`, an index constructed from a

`GHC.Data.Graph.Directed` `Graph` that supports fast reachability

queries (in $O(1)$). This abstract data structure is exposed from

`GHC.Data.Graph.Directed.Reachability`.

This index is constructed from the module graph nodes and cached in

`ModuleGraph`, enabling efficient reachability queries on the module

graph. Previously, we'd construct a Map of Set of ModuleGraph nodes

which used a lot of memory (`O(n^2)` in the number of nodes) and cache

that in the `ModuleGraph`. By using the reachability index we get rid of

this space leak in the module graph -- even though the index is still

quadratic in the number of modules, it is much, much more space

efficient due to its representation using an IntMap of IntSet as opposed

to the transitive closure we previously cached.

In a memory profile of MultiLayerModules with 100x100 modules, memory

usage improved from 6GB residency to 2.8GB, out of which roughly 1.8GB

are caused by a second space leak related to ModuleGraph. On the same

program, it brings compile time from 7.5s to 5.5s.

Note how we simplify `checkHomeUnitsClosed` in terms of

`isReachableMany` and by avoiding constructing a second graph with the

full transitive closure -- it suffices to answer the reachability query

on the full graph without collapsing the transitive closure completely

into nodes.

Unfortunately, solving this leak means we have to do a little bit more

work since we can no longer cache the result of turning vertex indices

into nodes. This results in a slight regression in MultiLayerModulesTH_Make,

but results in large performance and memory wins when compiling large

amounts of modules.

This patch removes the unused `GHC.Linker.Loader.loadExpr` function.

It was moved from `GHC.Runtime.Linker.linkExpr` in `ghc-9.0` to

`GHC.Linker.Loader.loadExpr` in `ghc-9.2`, and remain completely

unused and untested ever since. There's also no third party user of

this function to my best knowledge, so let's remove this. Anyone who

wants to write their own GHC API function to load bytecode can consult

the source code in older release branches.

was using the linker's `mmapAnonForLinker`, which tries hard to ensure

Previously the structure of `mmapInRegion` concealed a subtle bug

concerning handling of `mmap` returning mappings below the beginning of

the desired region. Specifically, we would reset `p = result + bytes`

and then again reset `p = region->start` before looping around for

another iteration. This resulted in an infinite loop on FreeBSD.

Fixes #25492.

The 'ModuleGraph' abstraction represents the relationship and strucutre

of the modules being compiled. This structure is meant to be constructed

once at the start of compilation, and never changed again.

However, it's exposed interface was confusing and exposed too many

footguns which led to inneficient usages of the ModuleGraph. This commit

improves significantly the exported interface of ModuleGraph, taking

into consideration the recent improvements around reachability queries.

Since the ModuleGraph graphs and related structures (HPT, EPS) are

performance critical in the sense that somewhat simple mistakes can

cause bad leaks and non-linear memory usage, we want to have proper APIs

that guide efficient usage. This is a good step in that direction.

Code analysis shown that such optimization would be possible out of the box if `cachedIdentForId` allowed to do that for Haskell `Id`s which are represented by few JavaScript `Ident`s. It is a usual for strings which are represented at JavaScript as a pair of 2 values: the string content and the offset where to start reading actual string from the full content. Usually offset is 0 but technically we need to allow such complex structures to be treated as "global".

Enabling it there shown that `genToplevelRhs` and `globalOccs` had inaccuracies in their implementations:

1. `globalOccs` operated over JavaScript's `Ident`s but for complex structures it didn't pay attention to the fact that different Idents actually could be pointed to same Id. Now the algo is changed to calculate occurencies for Ids.

2. `genToplevelRhs` didn't assume that different Idents pointed to same Id can have mixed order of occurence. But actually the order is important. Strings are encoded into 2 variables where first is content and second is offset and their order are not interchangeable. It is fixed by regeneration Idents from collected Ids which is fine because all Idents generation is passed through the Cache and they are quasi-stable.
