These were changes are all triggered by #24471. 1. Make GHC.Core.Opt.SetLevels.lvlMFE behave better when there are many free variables. See Note [Large free-variable sets]. 2. Make GHC.Core.Opt.Arity.floatIn a bit lazier in its Cost argument. This benefits the common case where the ArityType turns out to be nullary. See Note [Care with nested expressions] 3. Make GHC.CoreToStg.Prep.cpeArg behave for deeply-nested expressions. See Note [Eta expansion of arguments in CorePrep] wrinkle (EA2). Compile times go down by up to 4.5%, and much more in artificial cases. (Geo mean of compiler/perf changes is -0.4%.) Metric Decrease: CoOpt_Read T10421 T12425

This is a temporary measure to improve CI reliability until a proper solution is developed. Works around #23942.
-
This commit adds an assertion to Bdescr() to assert the pointer is indeed heap allocated. This is useful to rule out RTS bugs that attempt to access non-existent block descriptor of a static closure, #24492 being one such example.
-
This commit exposes HeapAlloc.h as a public header. The intention is to expose HEAP_ALLOCED/HEAP_ALLOCED_GC, so they can be used in assertions in other public headers, and they may also be useful for user code.
-
This patch adds a -xr RTS option to control the size of virtual memory address space reserved by the two step allocator on a 64-bit platform, see added documentation for explanation. Closes #24498.

There were a few issues with the hackage links: 1. We were using the package id rather than the package name for the package links. This is fixed by now allowing the template to mention %pkg% or %pkgid% and substituing both appropiatly. 2. The `--haddock-base-url` flag is renamed to `--haddock-for-hackage` as the new base link works on a local or remote hackage server. 3. The "src" path including too much stuff, so cross-package source links were broken as the template was getting double expanded. Fixes #24086
-
The file mentioned some artifacts relating to the base library. I have renamed these to the new ghc-internal variants.
-
-
This adds the upload of ghc-internal and ghc-experimental to our scripts which upload packages to hackage.

Fix a bug in the x86 ncg where results would be wrong when the desired output register and one of the input registers were the same global. Also adds a tiny optimization to make use of the memory addressing support when convenient. Fixes #24496

cmmToRawCmmHook was added 4 years ago in d561c8f6. Its only user is the Asterius project, which has been archived and deprecated in favor of the ghc wasm backend. This patch starts deprecating cmmToRawCmmHook by placing a DEPRECATED pragma, and actual removal shall happen in a future GHC major release if no issue to oppose the deprecation has been raised in the meantime.

This enriched the `CtOrigin` for non-linear patterns to include data of the pattern that created the constraint (which can be quite useful if it occurs nested in a pattern) as well as an explanation why the pattern is non-restricted in (at least in some cases).

This implements Proposal 0475, introducing the `ListTuplePuns` extension which is enabled by default. Disabling this extension makes it invalid to refer to list, tuple and sum type constructors by using built-in syntax like `[Int]`, `(Int, Int)`, `(# Int#, Int# #)` or `(# Int | Int #)`. Instead, this syntax exclusively denotes data constructors for use with `DataKinds`. The conventional way of referring to these data constructors by prefixing them with a single quote (`'(Int, Int)`) is now a parser error. Tuple declarations have been moved to `GHC.Tuple.Prim` and the `Solo` data constructor has been renamed to `MkSolo` (in a previous commit). Unboxed tuples and sums now have real source declarations in `GHC.Types`. Unit and solo types for tuples are now called `Unit`, `Unit#`, `Solo` and `Solo#`. Constraint tuples now have the unambiguous type constructors `CTuple<n>` as well as `CUnit` and `CSolo`, defined in `GHC.Classes` like before. A new parser construct has been added for the unboxed sum data constructor declarations. The type families `Tuple`, `Sum#` etc. that were intended to provide nicer syntax have been omitted from this change set due to inference problems, to be implemented at a later time.

Here we enable documentation building on 1. Darwin: The sphinx toolchain was already installed so we enable html and manpages. 2. Rocky8: Full documentation (toolchain already installed) 3. Alpine: Full documetnation (toolchain already installed) 4. Windows: HTML and manpages (toolchain already installed) Fixes #24465

9.6.4 is currently broken due to #24050 Also update to use LLVM-15 rather than LLVM-11, which is out of date.
-
We have previously bumped the docker images to use 9.6.4, but neglected to bump the windows images until now.
-
I noticed that the "docs" target was needed after the libraries and executables were built. We can improve the parallelism by needing everything at once so that documentation can be built immediately after a library is built for example.

This test leads to a lot of contention when N>2 and becomes very slow. Let's reduce the amount of work we do to compensate. Resolves #24490

T23540 is fragile on 32-bit platforms. The root cause is usage of `getEvidenceTreesAtPoint`, which internally relies on `Name`'s `Ord` instance, which is indeterministic. The solution is adding a deterministic `Ord` instance for `EvidenceInfo` and sorting the evidence trees before pretty printing. Fixes #24449.

In nonmovingTidyWeaks we want to check if the key of a weak pointer lives in the non-moving heap. We do this by checking the flags of the block the key lives in. But we need to be careful with values that live outside the Haskell heap, since they will lack a block descriptor and looking for one may lead to a segfault. In this case we should just accept that it isn't on the non-moving heap. Resolves #24492

Ever since the removal of the make build system, the in tree lndir hasn't been actually built, so this patch removes it.

In pursuit of #15560 and #17957 and generally removing redundancy.

See added comment for details. Closes #24423.

Its payload was used only for a small optimization in genAlts, avoiding a few assignments for programs of this form: case NormalDataCon arg1 arg2 of x { NormalDataCon x1 x2 -> ... ; } But when compiling with optimizations, this sort of code is generally eliminated by case-of-known-constructor in Core-to-Core. So it doesn't seem worth tracking and cleaning up again in StgToJS. -
- Use ClosureType for InfoProv.ipDesc. - Use ClosureType for CloneStack.closureType. - Now ghc-heap re-exports this type from ghc-internal. See the accompanying CLC proposal: https://github.com/haskell/core-libraries-committee/issues/210 Resolves #22600

When calling as `cc`, GCC does not outputs lowercased "gcc" at least in 13.2.1 version here. ``` $ cc --version cc (GCC) 13.2.1 20230801 ... ``` This fails the check and outputs the confusing message: `configure: $CC is not gcc; assuming it's a reasonably new C compiler` This patch makes it check for upper-cased "GCC" too so that it works correctly: ``` checking version of gcc... 13.2.1 ```

This commit enables parallelism when the hadrian/ghci scripts are called in CI. The time bottleneck is in the hadrian build step, but previously the build step wasn't parallelized.
