Towards #23868
-
This is copied from m4/ghc_convert_vendor.m4 Towards #23868
-
We were not normalising the target triple anymore like we did with the old make build system. Fixes #23856
-
This allows you to load ghc-toolchain and ghc-toolchain-bin into HLS.
-
The motivation for the flag is given in #21917.

The class is defined as class HasAnnotation e where noAnnSrcSpan :: SrcSpan -> e This generalises noAnnSrcSpan, and allows noLocA :: (HasAnnotation e) => a -> GenLocated e a noLocA = L (noAnnSrcSpan noSrcSpan)

In the `StgRhsCon` case of `GHC.Stg.Debug.collectStgRhs`, we were not coming up with an initial source span based on the span of the binder, which was causing instance dictionaries without dynamic superclass constraints to not have source locations in their IPE info. Now they do. Resolves #24005

Fixes #23802

Previously `NONMOVING_SEGMENT_MASK` and friends were defined with the `UL` size suffix. However, this is wrong on LLP64 platforms like Windows, where `long` is 32-bits. Fixes #23003. Fixes #24042.

This reverts commit 1c18d3b4. `-optP` should pass options to the preprocessor, that might be a very different program to the C compiler, so passing the options to the C compiler is likely to result in `-optP` being useless. Fixes #17185 and #21291

This is a bit of a shot in the dark to fix #24033, which appears to be another instance of #21712. For some reason the ld-override logic *still* appears to be active on Darwin targets (or at least one). Consequently, on misconfigured systems we may choose a non-`ld64` linker. It's a bit unclear exactly what happened in #24033 but ultimately the check added for #21712 was not quite right, checking for the `ghc_host_os` (the value of which depends upon the bootstrap compiler) instead of the target platform. Fix this. Fixes #24033.

This fixes #21062. No test case, because triggering this code seems challenging.

We currently use the Monoid class as a constraint on Exact Print Annotation functions, so we can use mempty. But this leads to requiring Semigroup instances too, which do not always make sense. Instead, introduce a class NoAnn, with a function noAnn analogous to mempty. Closes #20372 Updates haddock submodule

Rewrite conditional jump instructions with offsets >= 1MB to use unconditional jumps to avoid overflowing the immediate. Fixes #23746

This MR is pure refactoring (#23916): * Combine `HsLam` and `HsLamCase` * Combine `HsCmdLam` and `HsCmdLamCase` This just arranges to treat uniformly \x -> e \case pi -> ei \cases pis -> ie In the exising code base the first is treated differently to the latter two. No change in behaviour. More specifics: * Combine `HsLam` and `HsLamCase` (constructors of `Language.Haskell.Syntax.Expr.HsExpr`) into one data construtor covering * Lambda * `\case` * `\cases` * The new `HsLam` has an argument of type `HsLamVariant` to distinguish the three cases. * Similarly, combine `HsCmdLam` and `HsCmdLamCase` (constructors of `Language.Haskell.Syntax.Expr.HsCmd` ) into one. * Similarly, combine `mkHsLamPV` and `mkHsLamCasePV` (methods of class `DisambECP`) into one. (Thank you Alan Zimmerman.) * Similarly, combine `LambdaExpr` and `LamCaseAlt` (constructors of `Language.Haskell.Syntax.Expr.HsMatchContext`) into one: `LamAlt` with a `HsLamVariant` argument. * Similarly, combine `KappaExpr` and `ArrowLamCaseAlt` (constructors of `Language.Haskell.Syntax.Expr.HsArrowMatchContext`) into one: `ArrowLamAlt` with a `HsLamVariant` argument. * Similarly, combine `PsErrLambdaInPat` and `PsErrLambdaCaseInPat` (constructors of `GHC.Parser.Errors.Ppr.PsError`) into one. * Similarly, combine `PsErrLambdaInPat` and `PsErrLambdaCaseInPat` (constructors of `GHC.Parser.Errors.Ppr.PsError`) into one. * In the same `PsError` data type, combine `PsErrLambdaCmdInFunAppCmd` and `PsErrLambdaCaseCmdInFunAppCmd` into one. * In the same `PsError` data tpye, combine `PsErrLambdaInFunAppExpr` and `PsErrLambdaCaseInFunAppExpr` into one. p* Smilarly combine `ExpectedFunTyLam` and `ExpectedFunTyLamCase` (constructors of `GHC.Tc.Types.Origin.ExpectedFunTyOrigin`) into one. Phew!

Fixes #23612 , #23607, #23998 and #23666. MR: !11026 The fingerprinting logic in `Iface.Recomp` failed lookups when processing decls containing breakpoints for two reasons: * IfaceBreakpoint created binders for free variables instead of expressions * When collecting free names for the dependency analysis for fingerprinting, breakpoint FVs were skipped

This commit adds new Hadrian targets: codes, codes:used - list all used diagnostic codes codes:outdated - list outdated diagnostic codes This allows users to easily query GHC for used and outdated diagnostic codes, e.g. hadrian/build -j --flavour=<..> codes will list all used diagnostic codes in the command line by running the lint-codes utility in the "list codes" mode of operation. The diagnostic code consistency and coverage test is still run as usual, through the testsuite: hadrian/build test --only="codes"
