With this change, the type/kind of an object as well as it's category and definition site are added to the output of the :doc command for each object matching the argument string.

The ccall calling convention doesn't support varargs functions, so switch to capi instead. See https://ghc.gitlab.haskell.org/ghc/doc/users_guide/exts/ffi.html#varargs-not-supported-by-ccall-calling-convention

As noted in #19179, conc059 can sometimes fail due to too short of a delay in the its Haskell threads. Address this by increasing the delay by an order of magnitude to 5 seconds. While I'm in town I refactored the test to eliminate a great deal of unnecessary platform dependence, eliminate use of the deprecated usleep, and properly handle interruption by signals. Fixes #19179.

We don't run the testsuite in cross-compiled builds so there is nothing to push.

Previously lookupSymbol_PEi386 would call lookupSymbol while holding linker_mutex. Fix this by rather calling `lookupDependentSymbol`. This is safe because lookupSymbol_PEi386 unconditionally holds linker_mutex. Happily, this un-breaks `T12771`, `T13082_good`, and `T14611`, which were previously marked as broken due to #18718. Closes #19155.

When checking n_returning_tasks.

These are the two remaining non-atomic accesses to `wakeup` which were missed by the original TSAN patch.
-
This check is merely a service to the user; no reason to synchronize.

Solves #19147. When n_capabilities > 1 we were not correctly accounting for gc time for sequential collections. In this case par_n_gcthreads == 1, however it is not guaranteed that the single gc thread is capability 0. A similar issue for copied is addressed as well.

- Renamed new "update function" to "operator" from synopses - More accurate divergence conditions. - Fewer references to the Tree structure in examples, which may not have the definition close-by in context in other modules, e.g. Prelude. - Improved description of foldlM and foldrM - More detail on Tree instance construction - Misc fixes

ghcconfig.h, which depends upon ghcautoconf.h, and is a runtime dependency of deriveConstants. This is essentially a continuation of #18290.

This commit removes the errShortString field from the ErrMsg type, allowing us to cleanup a lot of dynflag-dependent error functions, and move them in a more specialised 'GHC.Driver.Errors' closer to the driver, where they are actually used. Metric Increase: T4801 T9961

* Mention changed in profiler's treatment of PINNED closures * Fix formatting * Move plugins-relevant changes to GHC API section

The weak pointer check in `checkGenWeakPtrList` previously failed to account for dead weak pointers. This caused `fptr01` to fail in the `sanity` way. Fixes #19162.

The refactoring in ed57c3a9 failed to initialize this field, resulting in no exports being registered. A very silly bug and yet somehow none of our tests caught it. See #18548. Fixes #19149.
-
For interactive evaluations set the field `DynFlags.dumpPrefix` to the GHCi internal module name. The GHCi module name for an interactive evaluation is something like `Ghci9`. To avoid user confusion, don't dump any data for GHCi internal evaluations. Extend the comment for `DynFlags.dumpPrefix` and fix a little typo in a comment about the GHCi internal module names.

Progress towards #19026. The type was added before, but not its primops. We follow the conventions in 36fcf9ed and 2c959a18 for names and testing. Along with the previous 8- and 16-bit primops, this will allow us to avoid many conversions for 8-, 16-, and 32-bit sized numeric types. Co-authored-by:

This flag requires that there be no space between the filename and the argument.
-
As noted in #9666, the mark-region GC is not compatible with heap profiling. Also add documentation for this flag. Closes #9666.
-
But only when profiling or DEBUG are enabled. Fixes #17572.
-
This is necessary since the user may enable `+RTS -hT` at any time.
-
It turns out that this was fairly straightforward to implement since we are now pretty careful about zeroing slop.
-
Move the logic for taking censuses of "normal" and pinned blocks to their own functions.

Before this patch the compiler depended on the RTS way (threaded or not) to use atomic incrementation or not. This is wrong because the RTS is supposed to be switchable at link time, without recompilation. Now we always use atomic incrementation of the unique counter.
