ghc-toolchain: Match CPP args with configure script
At the moment we need ghc-toolchain to precisely match the output as
provided by the normal configure script. The normal configure script
(FP_HSCPP_CMD_WITH_ARGS) branches on whether we are using clang or gcc
so we match that logic exactly in ghc-toolchain.
The old implementation (which checks if certain flags are supported) is
better but for now we have to match to catch any potential errors in the
configuration.
Ticket: #23720

configure: Fix `-Wl,--no-as-needed` check
The check was failing because the args supplied by $$1 were quoted which
failed because then the C compiler thought they were an input file.

configure: Add flag which turns ghc-toolchain check into error
We want to catch these errors in CI, but first we need to a flag which

ci: Enable --enable-strict-ghc-toolchain-check for all CI jobs
This will cause any CI job to fail if we have a mismatch between what
ghc-toolchain reports and what ./configure natively reports. Fixing
these kinds of issues is highest priority for 9.10 release.

Pass user-specified options to ghc-toolchain
The current user interface to configuring target toolchains is `./configure`.
In !9263 we added a new tool to configure target toolchains called
`ghc-toolchain`, but the blessed way of creating these toolchains is
still through configure.
However, we were not passing the user-specified options given with the
`./configure` invocation to the ghc-toolchain tool.
This commit remedies that by storing the user options and environment
variables in USER_* variables, which then get passed to GHC-toolchain.
The exception to the rule is the windows bundled toolchain, which
overrides the USER_* variables with whatever flags the windows bundled
toolchain requires to work.
We consider the bundled toolchain to be effectively the user specifying
options, since the actual user delegated that configuration work.
Closes #23678

Only check for no_compact_unwind support on darwin
While writing ghc-toolchain we noticed that the
FP_PROG_LD_NO_COMPACT_UNWIND check is subtly wrong. Specifically, we
pass -Wl,-no_compact_unwind to cc. However, ld.gold interprets this as
-n o_compact_unwind, which is a valid argument.

Add some javascript special cases to ghc-toolchain
On javascript there isn't a choice of toolchain but some of the
configure checks were not accurately providing the correct answer.
1. The linker was reported as gnu LD because the --version output
mentioned gnu LD.
2. The --target flag makes no sense on javascript but it was just
ignored by the linker, so we add a special case to stop ghc-toolchain
thinking that emcc supports --target when used as a linker.

Add ldOverrideWhitelist to only default to ldOverride on windows/linux
On some platforms - ie darwin, javascript etc we really do not want to
allow the user to use any linker other than the default one as this
leads to all kinds of bugs. Therefore it is a bit more prudant to add a
whitelist which specifies on which platforms it might be possible to use
a different linker.

ghc-toolchain: Add format mode to normalise differences before diffing.
The "format" mode takes an "--input" and "--ouput" target file and
formats it.
This is intended to be useful on windows where the
configure/ghc-toolchain target files can't be diffed very easily because
the path separators are different.

configure: MergeObjsCmd - distinguish between empty string and unset variable
If `MergeObjsCmd` is explicitly set to the empty string then we should
assume that MergeObjs is just not supported.
This is especially important for windows where we set MergeObjsCmd to ""

ghc-toolchain: Configure Cpp and HsCpp correctly when user specifies flags
In ghc-toolchain, we were only /not/ configuring required flags when the
user specified any flags at all for the of the HsCpp and Cpp tools.
Otherwise, the linker takes into consideration the user specified flags
to determine whether to search for a better linker implementation, but
already configured the remaining GHC and platform-specific flags
regardless of the user options.
Other Tools consider the user options as a baseline for further
configuration (see `findProgram`), so #23689 is not applicable.
Closes #23689

Use unsatisfiable for missing methods w/ defaults
When a class instance has an Unsatisfiable constraint in its context
and the user has not explicitly provided an implementation of a method,
we now always provide a RHS of the form `unsatisfiable @msg`, even
if the method has a default definition available. This ensures that,
when deferring type errors, users get the appropriate error message
instead of a possible runtime loop, if class default methods were
defined recursively.
Fixes #23816

set of accessors with clear semantics.

EPA: Use Introduce [DeclTag] in AnnSortKey
The AnnSortKey is used to keep track of the order of declarations for
printing when the container has split them apart.
This applies to HsValBinds and ClassDecl, ClsInstDecl.
When making modifications to the list of declarations, the new order
must be captured for when it must be printed. For each list of
declarations (binds and sigs for a HsValBind) we can just store the
list in order.
To recreate the list when printing, we must merge them, and this is
what the AnnSortKey records. It used to be indexed by SrcSpan, we now
simply index by a marker as to which list to take the next item from.

Don't attempt pattern synonym error recovery
This commit gets rid of the pattern synonym error recovery mechanism
(recoverPSB). The rationale is that the fake pattern synonym binding
that the recovery mechanism introduced could lead to undesirable
knock-on errors, and it isn't really feasible to conjure up a
satisfactory binding as pattern synonyms can be used both in expressions
and patterns.
See Note [Pattern synonym error recovery] in GHC.Tc.TyCl.PatSyn.
It isn't such a big deal to eagerly fail compilation on a pattern synonym
that doesn't typecheck anyway.

Abstract windows toolchain setup
This commit splits up the windows toolchain setup logic into two
functions.
* FP_INSTALL_WINDOWS_TOOLCHAIN - deals with downloading the toolchain if
it isn't already downloaded
* FP_SETUP_WINDOWS_TOOLCHAIN - sets the environment variables to point
to the correct place
FP_SETUP_WINDOWS_TOOLCHAIN is abstracted from the location of the mingw
toolchain and also the eventual location where we will install the
toolchain in the installed bindist.
This is the first step towards #23608

Generate build.mk for bindists
The config.mk.in script was relying on some variables which were
supposed to be set by build.mk but therefore never were when used to
install a bindist.
Specifically
* BUILD_PROF_LIBS to determine whether we had profiled libraries or not
* DYNAMIC_GHC_PROGRAMS to determine whether we had shared libraries or
not
Not only were these never set but also not really accurate because you
could have shared libaries but still statically linked ghc executable.
In addition variables like GhcLibWays were just never used, so those
have been deleted from the script.
Now instead we generate a build.mk file which just directly specifies
which RtsWays we have supplied in the bindist and whether we have
DYNAMIC_GHC_PROGRAMS.

hadrian: Add reloc-binary-dist-* targets
This adds a command line option to build a "relocatable" bindist.
The bindist is created by first creating a normal bindist and then
installing it using the `RelocatableBuild=YES` option. This creates a
bindist without any wrapper scripts pointing to the libdir.
The motivation for this feature is that we want to ship relocatable
bindists on windows and this method is more uniform than the ad-hoc
method which lead to bugs such as #23608 and #23476
The relocatable bindist can be built with the "reloc-binary-dist" target
and supports the same suffixes as the normal "binary-dist" command to
specify the compression style.

This commit changes how hints are handled in conjunction with
constraint solver report messages.
Instead of storing `[GhcHint]` in the TcRnSolverReport error constructor,
we compute the hints depending on the underlying TcSolverReportMsg.
This disentangles the logic and makes it easier to add new hints for
certain errors.

This commit performs boot-file consistency checking for TyCons into
checkValidTyCl. This ensures that we eagerly catch any mismatches,
which prevents the compiler from seeing these inconsistencies and
panicking as a result.
See Note [TyCon boot consistency checking] in GHC.Tc.TyCl.
Fixes #16127

Refactor estimation of stack info table provenance
This commit greatly refactors the way we compute estimated provenance for stack
info tables. Previously, this process was done using an entirely separate traversal
of the whole Cmm code stream to build the map from info tables to source locations.
The separate traversal is now fused with the Cmm code generation pipeline in
GHC.Driver.Main.
This results in very significant code generation speed ups when -finfo-table-map is
enabled. In testing, this patch reduces code generation times by almost 30% with
-finfo-table-map and -O0, and 60% with -finfo-table-map and -O1 or -O2 .
Fixes #23103

Add a test checking overhead of -finfo-table-map
We want to make sure we don't end up with poor codegen performance resulting from
-finfo-table-map again as in #23103. This test adds a performance test tracking
total allocations while compiling ExactPrint with -finfo-table-map.

llvmGen: Don't pass stack alignment via command line
As of https://reviews.llvm.org/D103048 LLVM no longer supports the
`-stack-alignment=...` flag. Instead this information is passed via a
module flag metadata node.
This requires dropping support for LLVM 11 and 12.

CorePrep: Eliminate EmptyCase and unsafeEqualityProof in CoreToStg instead
We eliminate EmptyCase by way of `coreToStg (Case e _ _ []) = coreToStg e` now.
The main reason is that it plays far better in conjunction with eta expansion
(as we aim to do for arguments in CorePrep, #23083), because we can discard
any arguments, `(case e of {}) eta == case e of {}`, whereas in `(e |> co) eta`
it's impossible to discard the argument.

Remove ScopedTypeVariables => TypeAbstractions
This commit implements [amendment 604](https://github.com/ghc-proposals/ghc-proposals/pull/604/)
to [GHC proposal 448](https://github.com/ghc-proposals/ghc-proposals/pull/448)
by removing the implication of language extensions
ScopedTypeVariables => TypeAbstractions
To limit breakage, we now allow type arguments in constructor patterns
when both ScopedTypeVariables and TypeApplications are enabled, but
we emit a warning notifying the user that this is deprecated behaviour
that will go away starting in GHC 9.12.

Make some evidence uses reachable by toHie
Resolves #23540, #23120
This adds spans to certain expressions in the typechecker and renamer,
and lets 'toHie' make use of those spans. Therefore the relevant
evidence uses for the following syntax will now show up under the
expected nodes in 'HieAst's:
- Overloaded literals ('IsString', 'Num', 'Fractional')
- Natural patterns and N+k patterns ('Eq', 'Ord', and instances from the
overloaded literals being matched on)
- Arithmetic sequences ('Enum')
- Monadic bind statements ('Monad')
- Monadic body statements ('Monad', 'Alternative')
- ApplicativeDo ('Applicative', 'Functor')
- Overloaded lists ('IsList')
Also see Note [Source locations for implicit function calls]
In the process of handling overloaded lists I added an extra 'SrcSpan'
field to 'VAExpansion' - this allows us to more accurately reconstruct
the locations from the renamer in 'rebuildHsApps'. This also happens to
fix #23120.

Don't bundle children for non-parent Avails
We used to bundle all children of the parent Avail with things that

class C a where
type T a

we would bundle the whole Avail (C, T, meth) with all of C, T and meth,
instead of only with C.

Neither has anything to do with `foldl'`, so I conclude that both are flaky.

Implement Or Patterns (Proposal 0522)
This commit introduces a language extension, `OrPatterns`, as described in proposal 0522.
It extends the syntax by the production
`pat -> (one of pat1, ..., patk)`.
The or-pattern `pat` succeeds iff one of the patterns `pat1`, ..., `patk` succeed, in this order.
Currently, or-patterns cannot bind variables. They are still of great use as they discourage the use of wildcard patterns in favour of writing out all "default" cases explicitly:
```
isIrrefutableHsPat pat = case pat of
...
(one of WildPat{}, VarPat{}, LazyPat{})
= True
(one of PArrPat{}, ConPatIn{}, LitPat{}, NPat{}, NPlusKPat{}, ListPat{})
= False
```
This makes code safer where data types are extended now and then - just like GHC's `Pat` in the example when adding the new `OrPat` constructor. This would be catched by `-fwarn-incomplete-patterns`, but not when a wildcard pattern was used.
