One of the side-effects of this change is shared objects are now loaded eagerly (i.e. with `RTLD_NOW`). This is needed by NativeObj to ensure full visibility of the mappings of the loaded object, which is in turn needed for safe shared object unloading. Unfortunately, this change subtly regressed, causing compilation failures in some programs. Specifically, shared objects which refer to undefined symbols (e.g. which may be usually provided by either the executable image or libraries loaded via `dlopen`) will fail to load with eager binding. This is problematic as GHC loads all package dependencies while, e.g., evaluating TemplateHaskell splices. This results in compilation failures in programs depending upon (but not using at compile-time) packages with undefined symbol references. To mitigate this NativeObj now first attempts to load an object via eager binding, reverting to lazy binding (and disabling unloading) on failure. See Note [Don't fail due to RTLD_NOW]. Fixes #25943.

Also adds the sanity way to rts_clearMemory test to prevent future regression. Closes #26011.

If a stack overflow happens between the creation of the stack frame for BCO_1 and BCO_N the RTS might move BCO_N to a new stack chunk while leaving BCO_1 in place, invalidating a simple offset based reference to the outer stack frames. Therefore `ReadSpW` first performs a bounds check to ensure that accesses onto the stack will succeed. If the target address would not be a valid location for the current stack chunk then `slow_spw` function is called, which dereferences the underflow frame to adjust the offset before performing the lookup. ┌->--x | CHK_1 | | CHK_2 | | | |---------| |---------| | └-> | BCO_1 | | UD_FLOW | -- x |---------| |---------| | | ...... | | |---------| | PUSH_L <n> | BCO_ N | ->-┘ |---------| Fixes #25750 (cherry picked from commit f4da90f11e3a3a634ec3edb6d70d96fe3515b726) - - - - - 63480835 by Ben Gamari at 2025-09-04T17:54:58+05:30 base: Note strictness changes made in 4.16.0.0 Addresses #25886.

Type data declarations end up as `PromotedDataCon`s by the time Haddock performs this check, causing a panic. This commit extends `tyConStupidTheta` so that it returns an empty list for `PromotedDataCon`s. This decision was guided by the fact that type data declarations never have data type contexts (see (R1) in Note [Type data declarations]). Fixes #25739.

It should encode the exact length of the member payload, excluding any padding byte, otherwise malformed archive that extracts a broken object with an extra trailing byte could be created. Apart from the in-tree `T26120` test, I've also created an out-of-tree testsuite at https://github.com/TerrorJack/ghc-ar-quickcheck that contains QuickCheck roundtrip tests for `GHC.SysTools.Ar`. With this fix, simple roundtrip tests and `writeGNUAr`/GNU `ar` roundtrip test passes. There might be more bugs lurking in here, but this patch is still a critical bugfix already.

We wanted this to track the length of nonmovingHeap.free. But this isn't possible to do atomically. When this isn't accurate we can get a segfault by going past the end of the list.

Currently GHC considers cost centres as destructive to join contexts. Or in other words this is not considered valid: join f x = ... in ... -> scc<tick> jmp This makes the functionality of `-fprof-late-overloaded-calls` not feasible for join points in general. We used to try to work around this by putting the ticks on the rhs of the join point rather than around the jump. However beyond the loss of accuracy this was broken for recursive join points as we ended up with something like: rec-join f x = scc<tick> ... jmp f x Which similarly is not valid as the tick once again destroys the tail call. One might think we could limit ourselves to non-recursive tail calls and do something clever like: join f x = scc<tick> ... in ... jmp f x And sometimes this works! But sometimes the full rhs would look something like: join g x = .... join f x = scc<tick> ... -> jmp g x Which, would again no longer be valid. I believe in the long run we can make cost centre ticks non-destructive to join points. Or we could keep track of where we are/are not allowed to insert a cost centre. But in the short term I will simply disable the annotation of join calls under this flag.

This is now detected in the `Cast` case of `cprAnal`. The same reproducer made it clear that `isRecDataCon` lacked congruent handling for `AppTy` and `CastTy`, now fixed. Furthermore, the new repro case T25944 triggered this bug via an infinite loop in `cprFix`, caused by the infelicity in `isRecDataCon`. While it should be much less likely to trigger such an infinite loop now that `isRecDataCon` has been fixed, I made sure to abort the loop after 10 iterations and emitting a warning instead.

naturalAndNot ((2 ^ 65) .|. (2 ^ 3)) (2 ^ 3) 0

In contrast, `naturalAndNot` does not truncate when both arguments are larger than a `Word`, so this appears to be a bug.
Luckily, the fix is pretty easy: we just need to call `bigNatAndNotWord#` instead of truncating.

Fixes #26230
