During heap analysis, we noticed that during generation of
'mi_extra_decls' we have lots of duplicates for the instances:
* `IfaceTyConInfo NotPromoted IfaceNormalTyCon`
* `IfaceTyConInfo IsPromoted IfaceNormalTyCon`
which should be shared instead of duplicated. This duplication increased
the number of live bytes by around 200MB while loading the agda codebase
into GHCi.
These instances are created during `CoreToIface` translation, in
particular `toIfaceTyCon`.
The generated core looks like:
toIfaceTyCon
= \ tc_sjJw ->
case $wtoIfaceTyCon tc_sjJw of
{ (# ww_sjJz, ww1_sjNL, ww2_sjNM #) ->
IfaceTyCon ww_sjJz (IfaceTyConInfo ww1_sjNL ww2_sjNM)
}
whichs removes causes the sharing to work propery.
Adding explicit sharing, with NOINLINE annotations, changes the core to:
toIfaceTyCon
= \ tc_sjJq ->
case $wtoIfaceTyCon tc_sjJq of { (# ww_sjNB, ww1_sjNC #) ->
IfaceTyCon ww_sjNB ww1_sjNC
}
which looks much more like sharing is happening.
We confirmed via ghc-debug that all duplications were eliminated and the
number of live bytes are noticeably reduced.

Uses responseFile syntax.
The issue arises when GHC is installed on windows into a location that
has a space, for example the user name is 'Fake User'.
The $topdir will also contain a space, consequentially.
When we resolve the top dir in the string `-I$topdir/mingw/include`,
then `words` will turn this single argument into `-I/C/Users/Fake` and
`User/.../mingw/include` which trips up the flag argument parser of
various tools such as gcc or clang.
We avoid this by escaping the $topdir before replacing it in
`initSettngs`.
Additionally, we allow to escape spaces and quotation marks for
arguments in `settings` file.
Add regression test case to count the number of options after variable
expansion and argument escaping took place.
Additionally, we check that escaped spaces and double quotation marks are
correctly parsed.

Before this patch, the global package database was always assumed to be
in libdir </> package.conf.d.
This causes issues in GHC's build system because there are sometimes
situations where the package database you need to use is not located in
the same place as the settings file.
* The stage1 compiler needs to use stage1 libraries, so we should set
"Global Package DB" for the stage1 compiler to the stage1 package
database.
* Stage 2 cross compilers need to use stage2 libraries, so likewise, we
should set the package database path to `_build/stage2/lib/`
* The normal situation is where the stage2 compiler uses stage1
libraries. Then everything lines up.
* When installing we have rearranged everything so that the settings
file and package database line up properly, so then everything should
continue to work as before. In this case we set the relative package
db path to `package.conf.d`, so it resolves the same as before.
* ghc-pkg needs to be modified as well to look in the settings file fo
the package database rather than assuming the global package database
location relative to the lib folder.
* Cabal/cabal-install will work correctly because they query the global
package database using `--print-global-package-db`.
A reasonable question is why not generate the "right" settings files in
the right places in GHC's build system. In order to do this you would
need to engineer wrappers for all executables to point to a specific
libdir. There are also situations where the same package db is used by
two different compilers with two different settings files (think stage2
cross compiler and stage3 compiler).
In short, this 10 line patch allows for some reasonable simplifications
in Hadrian at very little cost to anything else.
Fixes #24502

Don't use bigNatFromWord#, because that's terrible:
* We shouldn't have to traverse a linked list at run-time
to build a BigNat# literal. That's just silly!
* The static List object we have to create is much larger
than the actual BigNat#'s contents, bloating code size.
* We have to read the corresponding interface file,
which causes un-tracked implicit dependencies. (#23942)
Instead, encode them into the appropriate platform-dependent
sequence of bytes, and generate code that copies these bytes
at run-time from an Addr# literal into a new ByteArray#.
A ByteArray# literal would be the correct thing to generate,
but these are not yet supported; see also #17747.
Somewhat surprisingly, this change results in a slight
reduction in compiler allocations, averaging around 0.5%
on ghc's compiler performance tests, including when compiling
programs that contain no bignum literals to begin with.
The specific cause of this has not been investigated.
Since this lowering no longer reads the interface file for
GHC.Num.BigNat, the reasoning in Note [Depend on GHC.Num.Integer]
is obsoleted. But the story of un-tracked built-in dependencies
remains complex, and Note [Tracking dependencies on primitives]
now exists to explain this complexity.
Additionally, many empty imports have been modified to refer to
this new note and comply with its guidance. Several empty imports
necessary for other reasons have also been given brief explanations.

Heap analysis showed that `IfaceTyCon` retains a thunk to
`IfaceTyConInfo`, defeating the sharing of the most common instances of
`IfaceTyConInfo`.
We make sure the indirection is removed by adding bang patterns to
`IfaceTyCon`.
Experimental results on the agda code base, where the `mi_extra_decls`
were read from disk:
Before this change, we observe around 8654045 instances of:
`IfaceTyCon[Name,THUNK_1_0]`
But these thunks almost exclusively point to a shared value!
Forcing the thunk a little bit more, leads to `ghc-debug` reporting:
`IfaceTyCon[Name:Name,IfaceTyConInfo]`
and a noticeable reduction of live bytes (on agda ~10%).

ghcup can apparently infer the output name of an artifact from its URL.
Consequently, we should only include the `dlOutput` field when it would
differ from the filename of `dlUri`.

This reverts commit c82770f57977a2b5add6e1378f234f8dd6153392.
The shellcheck suggestion is spurious and results in SUBST_TOOLDIR being a
no-op. `set` sets positional arguments for bash, but we want to set the variable
given as the first autoconf argument.

In #24563, we identified that IfaceAppArgs serialisation tags each
cons cell element with a discriminator byte. These bytes add up
quickly, blowing up interface files considerably when
'-fwrite-if-simplified-core' is enabled.
We compact the serialisation by writing out the length of
'IfaceAppArgs', followed by serialising the elements directly without
any discriminator byte.
This improvement can decrease the size of some interface files by up
to 35%.

Type operators differ from term operators in that they are lexically
classified as (type) constructors, not as (type) variables.
Prior to this change, promoteOccName did not account for this
difference, causing a scoping issue that affected RequiredTypeArguments.
type (!@#) = Bool
f = idee (!@#) -- Not in scope: ‘!@#’ (BUG)
Now we have a special case in promoteOccName to account for this.

In #24551, we abstracted a string literal binding over a type variable,
triggering a CoreLint error when that binding floated to top-level.
The solution implemented in this patch fixes this by re-doing dependency
analysis on a simplified recursive let binding that is about to be type
abstracted, in order to find the minimal set of type variables to abstract over.
See wrinkle (AB5) of Note [Floating and type abstraction] for more details.

Fixes for a bug in desugaring pattern synonyms matches, introduced

default wild patterns in a match. Now the wild pattern alternative is
simply ignored by the pm check as its origin is `Generated`.
The current code now matches the expected semantics according to the language spec.

A user may configure `LDFLAGS` but not `LD`. When choosing a linker, we
will prefer `ldd`, then `ld.gold`, then `ld.bfd` -- however, we have to
check for a working linker. If either of these fail, we try the next in
line.
However, we were not considering the `$LDFLAGS` when checking if these
linkers worked. So we would pick a linker that does not support the
current $LDFLAGS and fail further down the line when we used that linker
with those flags.
Fixes #24565, where `LDFLAGS=-Wl,-z,pack-relative-relocs` is not
supported by `ld.gold` but that was being picked still.

For issue #21506, we started cleaning the extended attributes of
binaries and libraries from the bindist *after* they were installed to
workaround notarisation (#17418), as part of `make install`.
However, the `ghc-toolchain` binary that is now shipped with the bindist
must be run at `./configure` time. Since we only cleaned the xattributes
of the binaries and libs after they were installed, in some situations
users would be unable to run `ghc-toolchain` from the bindist, failing
at configure time (#24554).
In this commit we move the xattr cleaning logic to the configure script.
Fixes #24554
