This:
- Hoists part of the condition outside of the initialization loop in

- Annotates one of the unlikely branches as unlikely, also in
`stg_newSmallArrayzh`.
- Adds a couple of annotations to `allocateMightFail` indicating which
branches are likely to be taken.
Together this gives about 5% improvement.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Fix faulty substitutions in StgCse (#11532).
`substBndr` should rename bindings which shadow existing ids.
However while it was renaming the bindings it was not adding proper substitutions
for renamed bindings.
Instead of adding a substitution of the form `old -> new` for renamed
bindings it mistakenly added `old -> old` if no replacement had taken
place while adding none if `old` had been renamed.
As a byproduct this should improve performance, as we no longer add
useless substitutions for unshadowed bindings.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Inline the definition of 'ap' in the Monad laws
The law as it is currently written is meaningless, because nowhere have
we defined the implementation of 'ap'. The reader of the Control.Monad
documentation is provided with only a type signature,
> ap :: Monad m => m (a -> b) -> m a -> m b
an informal description,
> In many situations, the liftM operations can be replaced by uses of
> ap, which promotes function application.
and a relationship between 'ap' and the 'liftM' functions
> return f `ap` x1 `ap` ... `ap` xn
> is equivalent to
> liftMn f x1 x2 ... xn
Without knowing how 'ap' is defined, a law involving 'ap' cannot
provide any guidance for how to write a lawful Monad instance, nor can
we conclude anything from the law.
I suspect that a reader equipped with the understanding that 'ap' was
defined prior to the invention of the Applicative class could deduce
that 'ap' must be defined in terms of (>>=), but nowhere as far as I can
tell have we written this down explicitly for readers without the
benefit of historical context.
If the law is meant to express a relationship among (<*>), (>>=), and
'return', it seems that it is better off making this statement directly,
sidestepping 'ap' altogether.

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].

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Fix Uncovered set of literal patterns
Issues #16289 and #15713 are proof that the pattern match checker did
an unsound job of estimating the value set abstraction corresponding to
the uncovered set.
The reason is that the fix from #11303 introducing `NLit` was
incomplete: The `LitCon` case desugared to `Var` rather than `LitVar`,
which would have done the necessary case splitting analogous to the
`ConVar` case.
This patch rectifies that by introducing the fresh unification variable
in `LitCon` in value abstraction position rather than pattern postition,
recording a constraint equating it to the constructor expression rather
than the literal. Fixes #16289 and #15713.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Fix #16518 with some more kind-splitting smarts
This patch corrects two simple oversights that led to #16518:
1. `HsUtils.typeToLHsType` was taking visibility into account in the
`TyConApp` case, but not the `AppTy` case. I've factored out the
visibility-related logic into its own `go_app` function and now
invoke `go_app` from both the `TyConApp` and `AppTy` cases.
2. `Type.fun_kind_arg_flags` did not properly split kinds with
nested `forall`s, such as
`(forall k. k -> Type) -> (forall k. k -> Type)`. This was simply
because `fun_kind_arg_flags`'s `FunTy` case always bailed out and
assumed all subsequent arguments were `Required`, which clearly
isn't the case for nested `forall`s. I tweaked the `FunTy` case
to recur on the result kind.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Tweak error messages for narrowly-kinded assoc default decls
This program, from #13971, currently has a rather confusing error
message:
```hs
class C a where
type T a :: k
type T a = Int
```
```
• Kind mis-match on LHS of default declaration for ‘T’
• In the default type instance declaration for ‘T’
In the class declaration for ‘C’
```
It's not at all obvious why GHC is complaining about the LHS until
you realize that the default, when printed with
`-fprint-explicit-kinds`, is actually `type T @{k} @* a = Int`.
That is to say, the kind of `a` is being instantiated to `Type`,
whereas it ought to be a kind variable. The primary thrust of this
patch is to weak the error message to make this connection
more obvious:
```
• Illegal argument ‘*’ in:
‘type T @{k} @* a = Int’
The arguments to ‘T’ must all be type variables
• In the default type instance declaration for ‘T’
In the class declaration for ‘C’
```
Along the way, I performed some code cleanup suggested by @rae in
https://gitlab.haskell.org/ghc/ghc/issues/13971#note_191287. Before,
we were creating a substitution from the default declaration's type
variables to the type family tycon's type variables by way of
`tcMatchTys`. But this is overkill, since we already know (from the
aforementioned validity checking) that all the arguments in a default
declaration must be type variables anyway. Therefore, creating the
substitution is as simple as using `zipTvSubst`. I took the
opportunity to perform this refactoring while I was in town.
Fixes #13971.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Generate straightline code for inline array allocation
GHC has an optimization for allocating arrays when the size is
statically known -- it'll generate the code allocating and initializing
the array inline (instead of a call to a procedure from
`rts/PrimOps.cmm`).
However, the generated code uses a loop to do the initialization. Since
we already check that the requested size is small (we check against
`maxInlineAllocSize`), we can generate faster straightline code instead.
This brings about 15% improvement for `newSmallArray#` in my testing and
slightly simplifies the code in GHC.

We are currently ignoring options set in the hiDir field of hsc_dflags
when looking for interface files while compiling in OneShot mode. This
is inconsistent with the behaviour of other directory redirecting fields
(such as objectDir or hieDir). It is also inconsistent with the
behaviour of compilation in CompManager mode (a.k.a `ghc --make`) which
looks for interface files in the directory set in hidir flag. This
changes Finder.hs so that we use the value of hiDir while looking for
interface in OneShot mode.

Previously, `singleConstructor` didn't handle singleton `COMPLETE` sets

in #15753.
This is fixed by making `singleConstructor` (now named
`singleMatchConstructor`) query `allCompleteMatches`, necessarily making
it effectful. As a result, most of this patch is concerned with
threading the side-effect through to `singleMatchConstructor`.
Unfortunately, this is not enough to completely fix the original
reproduction from #15753 and #15884, which are related to function
applications in pattern guards being translated too conservatively.

Fixes #16052
When the offset in `setByteArray#` is statically known, we can provide
better alignment guarantees then just 1 byte.
Also, memset can now do 64-bit wide sets.
The current memset intrinsic is not optimal however and can be
improved for the case when we know that we deal with
(baseAddress at known alignment) + offset
For instance, on 64-bit
`setByteArray# s 1# 23# 0#`
given that bytearray is 8 bytes aligned could be unrolled into
`movb, movw, movl, movq, movq`; but currently it is
`movb x23` since alignment of 1 is all we can embed into MO_Memset op.

GHC now works out-of-the-box (i.e. without any wrapper script) by
assuming that @bin@ and @lib@ directories sit next to each other. In
particular, its RUNPATH uses $ORIGIN-based relative path to find the
libraries.
However, to be good citizens we want to support the case where @bin@ and
@lib@ directories (respectively BINDIR and LIBDIR) don't sit next to
each other or are renamed. To do that the install script simply creates
GHC specific @bin@ and @lib@ siblings directories into:
LIBDIR/ghc-VERSION/{bin,lib}
Then it installs wrapper scripts into BINDIR that call the appropriate
programs into LIBDIR/ghc-VERSION/bin/.
The issue fixed by this patch is that libraries were not installed into
LIBDIR/ghc-VERSION/lib but directly into LIBDIR.

* simplifies registers to have GPR, Float and Double, by removing the SSE2 and X87 Constructors
* makes -msse2 assumed/default for x86 platforms, fixing a long standing nondeterminism in rounding
behavior in 32bit haskell code
* removes the 80bit floating point representation from the supported float sizes
* theres still 1 tiny bit of x87 support needed,
for handling float and double return values in FFI calls wrt the C ABI on x86_32,
but this one piece does not leak into the rest of NCG.
* Lots of code thats not been touched in a long time got deleted as a
consequence of all of this
all in all, this change paves the way towards a lot of future further
improvements in how GHC handles floating point computations, along with
making the native code gen more accessible to a larger pool of contributors.

When -a or --test-accept is passed, and if one runs the 'test' target, then
any test failing because of mismatching output and which is not expected to
fail will have its expected output adjusted by the test driver, effectively
considering the new output correct from now on.
When this flag is passed, hadrian's 'test' target becomes sensitive to the
PLATFORM and OS environment variable, just like the Make build system:
- when the PLATFORM env var is set to "YES", when accepting a result, accept it
for the current platform;
- when the OS env var is set to "YES", when accepting a result, accept it
for all wordsizes of the current operating system.
This can all be combined with `--only="..."` and `TEST="..." to only accept
the new output of a subset of tests.

Lint returns a pair (Maybe a, WarnsAndErrs). The Maybe monad
allows to handle an unrecoverable failure.
In case of such a failure, the error should be added to the second
component of the pair. If this is not done, Lint will silently
accept bad programs. This situation actually happened during
development of linear types. This adds a safeguard.

Directives in .ghci files in the current directory ("local .ghci")
can be overridden by global files. Change the order in which the
configs are loaded: global and $HOME/.ghci first, then local.
Also introduce a new field to GHCiState to control whether local
.ghci gets sourced or ignored. This commit does not add a way to
set this value (a subsequent commit will add this), but the .ghci
sourcing routine respects its value.

Besides the obvious benefits of being able to manipulate `TExp`'s of
unboxed types, this also simplified `-XDeriveLift` all while making
it more capable.
* `ghc-prim` is explicitly depended upon by `template-haskell`
* The following TH things are parametrized over `RuntimeRep`:
- `TExp(..)`
- `unTypeQ`
- `unsafeTExpCoerce`
- `Lift(..)`
* The following instances have been added to `Lift`:
- `Int#`, `Word#`, `Float#`, `Double#`, `Char#`, `Addr#`
- unboxed tuples of lifted types up to arity 7
- unboxed sums of lifted types up to arity 7
Ideally we would have levity-polymorphic _instances_ of unboxed
tuples and sums.
* The code generated by `-XDeriveLift` uses expression quotes
instead of generating large amounts of TH code and having
special hard-coded cases for some unboxed types.

Previously we would generate a local variable pointing after the array
header and use it to initialize the array elements. But we already use
stores with offset, so it's easy to just add the header to those offsets
during compilation and avoid generating the local variable (which would
become a LEA instruction when using native codegen; LLVM already
optimizes it away).

4 haddock tests assume that .haddock files have been produced, by using the
'req_haddock' modifier. The testsuite driver assumes that this condition is
satisfied if 'config.haddock' is non-empty, but before this patch Hadrian was
always passing the path to where the haddock executable should be, regardless
of whether it is actually there or not.
Instead, we now pass an empty config.haddock when we can't find all of
<build root>/docs/html/libraries/<pkg>/<pkg>.haddock>, where <pkg> ranges over
array, base, ghc-prim, process and template-haskell, and pass the path
to haddock when all those file exists. This has the (desired) effect of skipping
the 4 tests (marked as 'missing library') when the docs haven't been built,
and running the haddock tests when they have.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Stop misusing EWildPat in pattern match coverage checking
EWildPat is a constructor of HsExpr used in the parser to represent
wildcards in ambiguous positions:
* in expression context, EWildPat is turned into hsHoleExpr (see rnExpr)
* in pattern context, EWildPat is turned into WildPat (see checkPattern)
Since EWildPat exists solely for the needs of the parser, we could
remove it by improving the parser.
However, EWildPat has also been used for a different purpose since
8a50610: to represent patterns that the coverage checker cannot handle.
Not only this is a misuse of EWildPat, it also stymies the removal of
EWildPat.

The bulk of the work was done in #712, making settings be make/Hadrian
controlled. This commit then just moves the unlit command rules in
make/Hadrian from the `Config.hs` generator to the `settings` generator
in each build system.
I think this is a good change because the crucial benefit is *settings*
don't affect the build: ghc gets one baby step closer to being a regular
cabal executable, and make/Hadrian just maintains settings as part of
bootstrapping.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Pattern/expression ambiguity resolution
This patch removes 'EWildPat', 'EAsPat', 'EViewPat', and 'ELazyPat'
from 'HsExpr' by using the ambiguity resolution system introduced
earlier for the command/expression ambiguity.
Problem: there are places in the grammar where we do not know whether we
are parsing an expression or a pattern, for example:
do { Con a b <- x } -- 'Con a b' is a pattern
do { Con a b } -- 'Con a b' is an expression
Until we encounter binding syntax (<-) we don't know whether to parse
'Con a b' as an expression or a pattern.
The old solution was to parse as HsExpr always, and rejig later:
checkPattern :: LHsExpr GhcPs -> P (LPat GhcPs)
This meant polluting 'HsExpr' with pattern-related constructors. In
other words, limitations of the parser were affecting the AST, and all
other code (the renamer, the typechecker) had to deal with these extra
constructors.
We fix this abstraction leak by parsing into an overloaded
representation:
class DisambECP b where ...
newtype ECP = ECP { runECP_PV :: forall b. DisambECP b => PV (Located b) }
See Note [Ambiguous syntactic categories] for details.
Now the intricacies of parsing have no effect on the hsSyn AST when it
comes to the expression/pattern ambiguity.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Make equality constraints in kinds invisible
Issues #12102 and #15872 revealed something strange about the way GHC
handles equality constraints in kinds: it treats them as _visible_
arguments! This causes a litany of strange effects, from strange
error messages
(https://gitlab.haskell.org/ghc/ghc/issues/12102#note_169035)
to bizarre `Eq#`-related things leaking through to GHCi output, even
without any special flags enabled.
This patch is an attempt to contain some of this strangeness.
In particular:
* In `TcHsType.etaExpandAlgTyCon`, we propagate through the
`AnonArgFlag`s of any `Anon` binders. Previously, we were always
hard-coding them to `VisArg`, which meant that invisible binders
(like those whose kinds were equality constraint) would mistakenly
get flagged as visible.
* In `ToIface.toIfaceAppArgsX`, we previously assumed that the
argument to a `FunTy` always corresponding to a `Required`
argument. We now dispatch on the `FunTy`'s `AnonArgFlag` and map
`VisArg` to `Required` and `InvisArg` to `Inferred`. As a
consequence, the iface pretty-printer correctly recognizes that
equality coercions are inferred arguments, and as a result,
only displays them in `-fprint-explicit-kinds` is enabled.
* Speaking of iface pretty-printing, `Anon InvisArg` binders were
previously being pretty-printed like `T (a :: b ~ c)`, as if they
were required. This seemed inconsistent with other invisible
arguments (that are printed like `T @{d}`), so I decided to switch
this to `T @{a :: b ~ c}`.
Along the way, I also cleaned up a minor inaccuracy in the users'
guide section for constraints in kinds that was spotted in
https://gitlab.haskell.org/ghc/ghc/issues/12102#note_136220.
Fixes #12102 and #15872.

This required making the 'ghc-config-mk' variable overridable in

to point to '<build root>/test/ghcconfig' instead, which is where we
always put the test config.
Previously, we would build ghc-config and run it against the
GHC to be tested, a second time, while we're running the tests, because some

A follow-up to !696's, which attempted to clean up the error messages

attempt, !696, forgot to account for the possibility of duplicate
kind variable arguments, as in the following example:
```hs
class C (a :: j) where
type T (a :: j) (b :: k)
type T (a :: k) (b :: k) = k

This patch addresses this shortcoming by adding an additional check
for this. Fixes #13971 (hopefully for good this time).

1. If GHC is to be multi-target, these cannot be baked in at compile
time.
2. Compile-time flags have a higher maintenance than run-time flags.
3. The old way makes build system implementation (various bootstrapping
details) with the thing being built. E.g. GHC doesn't need to care
about which integer library *will* be used---this is purely a crutch
so the build system doesn't need to pass flags later when using that
library.
4. Experience with cross compilation in Nixpkgs has shown things work
nicer when compiler's can *optionally* delegate the bootstrapping the
package manager. The package manager knows the entire end-goal build
plan, and thus can make top-down decisions on bootstrapping. GHC can
just worry about GHC, not even core library like base and ghc-prim!

GHC Proposal #36 describes a transition plan away from CUSKs and to

1. Introduce a new extension, -XCUSKs, on by default, that detects CUSKs
as they currently exist.
2. We turn off the -XCUSKs extension in a few releases and remove it
sometime thereafter.
This patch implements phase 1 of this plan, introducing a new language
extension to control whether CUSKs are enabled. When top-level kind
signatures are implemented, we can transition to phase 2.

happy-1.19.10 has been released with a fix for --coerce in the presence

Previously, changing one of the .rst files from the user guide would not cause
the user guide to be rebuilt. This patch take a first stab at declaring the
documentation source files that our documentation rules depend on, focusing
on the .rst files only for now.
We eventually might want to rebuild docs when we, say, change the haddock style
file, but this level of tracking isn't really necessary for now.
This fixes #16645.
