<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">powerpc32: fix 64-bit comparison (#16465)
On powerpc32 64-bit comparison code generated dangling
target labels. This caused ghc build failure as:
$ ./configure --target=powerpc-unknown-linux-gnu && make
...
SCCs aren't in reverse dependent order
bad blockId n3U
This happened because condIntCode' in PPC codegen generated
label name but did not place the label into `cmp_lo` code block.
The change adds the `cmp_lo` label into the case of negative
comparison.

When ghc was built for powerpc32 built failed as:
It's a fallout of commit 3f46cffcc2850e68405a1
("PPC NCG: Refactor stack allocation code") where
word size used to be
II32/II64
and changed to
II8/panic "no width for given number of bytes"
widthFromBytes ((platformWordSize platform) `quot` 8)
The change restores initial behaviour by removing extra division.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Fix arity type of coerced types in CoreArity
Previously if we had
f |> co
where `f` had arity type `ABot N` and `co` had arity M and M < N,
`arityType` would return `ABot M` which is wrong, because `f` is only
known to diverge when applied to `N` args, as described in Note
[ArityType]:
If at = ABot n, then (f x1..xn) definitely diverges. Partial
applications to fewer than n args may *or may not* diverge.
This caused incorrect eta expansion in the simplifier, causing #16066.
We now return `ATop M` for the same expression so the simplifier can't
assume partial applications of `f |> co` is divergent.
A regression test T16066 is also added.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Put COMPLETE sigs into ModDetails with -fno-code (#16682)
`mkBootModDetailsTc`, which creates a special `ModDetails` when
`-fno-code` is enabled, was not properly filling in the `COMPLETE`
signatures from the `TcGblEnv`, resulting in incorrect pattern-match
coverage warnings. Easily fixed.
Fixes #16682.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Fix space leaks in dynLoadObjs (#16708)
When running the test suite on a GHC built with the `quick` build
flavour, `-fghci-leak-check` noticed some space leaks. Careful
investigation led to `Linker.dynLoadObjs` being the culprit.
Pattern-matching on `PeristentLinkerState` and a dash of `$!` were
sufficient to fix the issue. (ht to mpickering for his suggestions,
which were crucial to discovering a fix)
Fixes #16708.
