The definition of 'optSemi' claimed it had type
([Located a],Bool)
Note that its production actually returns ([Located Token],Bool):
: ';' { ([$1],True) } -- $1 :: Located Token
Due to an infelicity in the implementation of 'happy -c', it effectively
resulted in 'unsafeCoerce :: Token -> a'.
See https://github.com/simonmar/happy/pull/134
If any consumer of 'optSemi' tried to instantiate 'a' to something not
representationally equal to 'Token', they would experience a segfault.
In addition to that, this definition made it impossible to compile Parser.y
without the -c flag (as it's reliant on this bug to cast 'Token' to 'forall
a. a').

This addresses some glaring omissions from

This includes two bug fixes in profiling version of stg_ap_0_fast:
- PAPs allocated by stg_ap_0_fast are now correctly tagged. This
invariant is checked in Sanity.c:checkPAP.
(This was originally implemented in 2693eb11f5, later reverted with
ab55b4ddb7 because it revealed the bug below, but it wasn't clear at
the time whether the bug was the one below or something in the commit)
- The local variable `untaggedfun` is now marked as a pointer so it
survives GC.
With this we finally fix all known bugs caught in #15508. `concprog001`
now works reliably with prof+threaded and prof runtimes (with and
without -debug).

rlim_t is a signed type on FreeBSD, and the build fails with a
sign-compare error. Add explicit (unsigned) cast to handle this
case.

The initial motivation for this is to have a chance to run the binary
distribution rules in our Windows CI without having to install
sphinx-build and xelatex there, while retaining the ability to
generate haddocks. I just ended up extending this idea a little bit so
as to have control over whether we build haddocks, (sphinx) HTML manuals,
(sphinx) PDF manuals and (sphinx) manpages.

This function makes it easy to turn on `-Werror` in the correct manner
to mimic how CI turns on -Werror.

This fixes #16440, where the build system incorrectly concluded that the
`.subsections_via_symbols` assembler directive was supported on a Linux
system. This was caused by the fact that gcc was invoked with `-flto`;
when so-configured gcc does not call the assembler but rather simply
serialises its AST for compilation during the final link.
This is described in Note [autoconf assembler checks and -flto].

This fixes #16514: Xmm6-15 was restored based off rax instead of rsp.
The code was introduced in the fix for #14619.

Currently, the `hpc` submodule is pinned against the `wip/final-mfp`
branch, not against `master`. This pins it back against `master`.

A simple oversight. Fixes #16527.

This bumps `array` to version 0.5.4.0 so that we can distinguish
it with `MIN_VERSION_array` (as it introduces some changes to the
`Show` instance for `UArray`).

It should work to write an indefinite package using TemplateHaskell,
so long as all of the actual TH code lives outside of the package.
However, cleverness we had to build TH code even when building
with -fno-code meant that we attempted to build object code for
modules in an indefinite package, even when the signatures were
not instantiated. This patch disables said logic in the event
that an indefinite package is being typechecked.
