<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Export singleton function from Data.List
Data.OldList exports a monomorphized singleton function but
it is not re-exported by Data.List. Adding the export to
Data.List causes a conflict with a 14-year old function of the
same name and type by SPJ in GHC.Utils.Misc. We can't just remove
this function because that leads to a problems when building
GHC with a stage0 compiler that does not have singleton in
Data.List yet. We also can't hide the function in GHC.Utils.Misc
since it is not possible to hide a function from a module if the
module does not export the function. To work around this, all
places where the Utils.Misc singleton was used now use a qualified
version like Utils.singleton and in GHC.Utils.Misc we are very
specific about which version we export.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Remove ConDeclGADTPrefixPs
This removes the `ConDeclGADTPrefixPs` per the discussion in #18517.
Most of this patch simply removes code, although the code in the
`rnConDecl` case for `ConDeclGADTPrefixPs` had to be moved around a
bit:
* The nested `forall`s check now lives in the `rnConDecl` case for
`ConDeclGADT`.
* The `LinearTypes`-specific code that used to live in the
`rnConDecl` case for `ConDeclGADTPrefixPs` now lives in
`GHC.Parser.PostProcess.mkGadtDecl`, which is now monadic so that
it can check if `-XLinearTypes` is enabled.
Fixes #18157.

Fixes #18439 .
The rhs of the pattern guard was consumed with multiplicity one, while
the pattern assumed it was Many. We use Many everywhere instead.
This is behaviour consistent with that of `case` expression. See #18738.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">[macOS] improved runpath handling
In b592bd98ff25730bbe3c13d6f62a427df8c78e28 we started using
-dead_strip_dylib on macOS when lining dynamic libraries and binaries.
The underlying reason being the Load Command Size Limit in macOS
Sierra (10.14) and later.
GHC will produce @rpath/libHS... dependency entries together with a
corresponding RPATH entry pointing to the location of the libHS...
library. Thus for every library we produce two Load Commands. One to
specify the dependent library, and one with the path where to find it.
This makes relocating libraries and binaries easier, as we just need to
update the RPATH entry with the install_name_tool. The dynamic linker
will then subsitute each @rpath with the RPATH entries it finds in the
libraries load commands or the environement, when looking up @rpath
relative libraries.
-dead_strip_dylibs intructs the linker to drop unused libraries. This in
turn help us reduce the number of referenced libraries, and subsequently
the size of the load commands. This however does not remove the RPATH
entries. Subsequently we can end up (in extreme cases) with only a
single @rpath/libHS... entry, but 100s or more RPATH entries in the Load
Commands.
This patch rectifies this (slighly unorthodox) by passing *no* -rpath
arguments to the linker at link time, but -headerpad 8000. The
headerpad argument is in hexadecimal and the maxium 32k of the load
command size. This tells the linker to pad the load command section
enough for us to inject the RPATHs later. We then proceed to link the
library or binary with -dead_strip_dylibs, and *after* the linking
inspect the library to find the left over (non-dead-stripped)
dependencies (using otool). We find the corresponding RPATHs for each
@rpath relative dependency, and inject them into the library or binary
using the install_name_tool. Thus achieving a deadstripped dylib (and
rpaths) build product.
We can not do this in GHC, without starting to reimplement a dynamic
linker as we do not know which symbols and subsequently libraries are
necessary.
