* JS: replace "js" architecture with "javascript"wip/T22740Sylvain Henry2023-02-0641-91/+92
| | | | | | | | | | | | | | | Despite Cabal supporting any architecture name, `cabal --check` only supports a few built-in ones. Sadly `cabal --check` is used by Hackage hence using any non built-in name in a package (e.g. `arch(js)`) is rejected and the package is prevented from being uploaded on Hackage. Luckily built-in support for the `javascript` architecture was added for GHCJS a while ago. In order to allow newer `base` to be uploaded on Hackage we make the switch from `js` to `javascript` architecture. Fixes #22740. Co-authored-by: Ben Gamari <ben@smart-cactus.org>

* linker: Fix BFD import librariesTamar Christina2023-02-0310-29/+121
| | | | | | | | | | This commit fixes the BFD style import library support in the runtime linker. This was accidentally broken during the refactoring to clang and went unnoticed because clang itself is unable to generate the BFD style import libraries. With this change we can not link against both GCC or Clang produced libraries again and intermix code produced by both compilers.
* Windows: Remove mingwex dependencyRyan Scott2023-02-0314-260/+95
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The clang based toolchain uses ucrt as its math library and so mingwex is no longer needed. In fact using mingwex will cause incompatibilities as the default routines in both have differing ULPs and string formatting modifiers. ``` $ LIBRARY_PATH=/mingw64/lib ghc/_build/stage1/bin/ghc Bug.hs -fforce-recomp && ./Bug.exe [1 of 2] Compiling Main ( Bug.hs, Bug.o ) ghc.exe: | C:\Users\winferno\Software\ghc\_build\stage1\lib\x86_64-windows-ghc-9.5.20220908\base-4.17.0.0\libHSbase-4.17.0.0.a: unknown symbol `__imp___p__environ' ghc.exe: | C:\Users\winferno\Software\ghc\_build\stage1\lib\x86_64-windows-ghc-9.5.20220908\base-4.17.0.0\libHSbase-4.17.0.0.a: unknown symbol `__hscore_get_errno' ghc.exe: | C:\Users\winferno\Software\ghc\_build\stage1\lib\x86_64-windows-ghc-9.5.20220908\base-4.17.0.0\libHSbase-4.17.0.0.a: unknown symbol `base_ForeignziCziError_errnoToIOError_info' ghc.exe: | C:\Users\winferno\Software\ghc\_build\stage1\lib\x86_64-windows-ghc-9.5.20220908\base-4.17.0.0\libHSbase-4.17.0.0.a: unknown symbol `base_GHCziWindows_failIf2_closure' ghc.exe: | C:\Users\winferno\Software\ghc\_build\stage1\lib\x86_64-windows-ghc-9.5.20220908\base-4.17.0.0\libHSbase-4.17.0.0.a: unknown symbol `base_GHCziIOziEncodingziCodePageziAPI_mkCodePageEncoding_info' ghc.exe: | C:\Users\winferno\Software\ghc\_build\stage1\lib\x86_64-windows-ghc-9.5.20220908\base-4.17.0.0\libHSbase-4.17.0.0.a: unknown symbol `base_GHCziIOziEncodingziCodePage_currentCodePage_closure' ghc.exe: | C:\Users\winferno\Software\ghc\_build\stage1\lib\x86_64-windows-ghc-9.5.20220908\base-4.17.0.0\libHSbase-4.17.0.0.a: unknown symbol `base_GHCziIOziEncoding_getForeignEncoding_closure' ghc.exe: | C:\Users\winferno\Software\ghc\_build\stage1\lib\x86_64-windows-ghc-9.5.20220908\base-4.17.0.0\libHSbase-4.17.0.0.a: unknown symbol `base_ForeignziCziString_withCStringLen1_info' ghc.exe: | C:\Users\winferno\Software\ghc\_build\stage1\lib\x86_64-windows-ghc-9.5.20220908\base-4.17.0.0\libHSbase-4.17.0.0.a: unknown symbol `base_GHCziIOziHandleziInternals_zdwflushCharReadBuffer_info' ghc.exe: | C:\Users\winferno\Software\ghc\_build\stage1\lib\x86_64-windows-ghc-9.5.20220908\base-4.17.0.0\libHSbase-4.17.0.0.a: unknown symbol `base_GHCziIOziHandleziText_hGetBuf1_info' ghc.exe: | C:\Users\winferno\Software\ghc\_build\stage1\lib\x86_64-windows-ghc-9.5.20220908\base-4.17.0.0\libHSbase-4.17.0.0.a: unknown symbol `base_GHCziFingerprint_fingerprintString_closure' ghc.exe: | C:\Users\winferno\Software\ghc\_build\stage1\lib\x86_64-windows-ghc-9.5.20220908\base-4.17.0.0\libHSbase-4.17.0.0.a: unknown symbol `base_DataziTypeableziInternal_mkTrCon_closure' ghc.exe: | C:\Users\winferno\Software\ghc\_build\stage1\lib\x86_64-windows-ghc-9.5.20220908\base-4.17.0.0\libHSbase-4.17.0.0.a: unknown symbol `base_GHCziException_errorCallWithCallStackException_closure' ghc.exe: | C:\Users\winferno\Software\ghc\_build\stage1\lib\x86_64-windows-ghc-9.5.20220908\base-4.17.0.0\libHSbase-4.17.0.0.a: unknown symbol `base_GHCziErr_error_info' ghc.exe: | C:\Users\winferno\Software\ghc\_build\stage1\lib\x86_64-windows-ghc-9.5.20220908\template-haskell-2.19.0.0\libHStemplate-haskell-2.19.0.0.a: unknown symbol `base_DataziMaybe_fromJust1_info' ghc.exe: | C:\Users\winferno\Software\ghc\_build\stage1\lib\x86_64-windows-ghc-9.5.20220908\template-haskell-2.19.0.0\libHStemplate-haskell-2.19.0.0.a: unknown symbol `templatezmhaskell_LanguageziHaskellziTHziSyntax_IntPrimL_con_info' ghc.exe: ^^ Could not load 'templatezmhaskell_LanguageziHaskellziTHziLibziInternal_stringL_closure', dependency unresolved.

* gitlab-ci: Eliminate redundant ghc --info outputBen Gamari2023-02-031-2/+5
| | | | | | | Previously ci.sh would emit the output of `ghc --info` every time it ran when using the nix toolchain. This produced a significant amount of noise. See #22861.

* Disable unfolding sharing for interface files with core definitionsMatthew Pickering2023-02-0210-4/+56
| | | | | | | | | | | | | | | | | | | | | | Ticket #22807 pointed out that the RHS sharing was not compatible with -fignore-interface-pragmas because the flag would remove unfoldings from identifiers before the `extra-decls` field was populated. For the 9.6 timescale the only solution is to disable this sharing, which will make interface files bigger but this is acceptable for the first release of `-fwrite-if-simplified-core`. For 9.8 it would be good to fix this by implementing #20056 due to the large number of other bugs that would fix. I also improved the error message in tc_iface_binding to avoid the "no match in record selector" error but it should never happen now as the entire sharing logic is disabled. Also added the currently broken test for #22807 which could be fixed by !6080 Fixes #22807

Note that this is a temporary solution until !9515 is merged. Key point: The CI runs hadrian on the built cross compiler _but not_ on the bindist. Other Highlights: - stm submodule gets a bump to mark tests as broken - several tests are marked as broken or are fixed by adding more - conditions to their test runner instance.

* Bump DOCKER_REV to use alpine image without LLVM installedMatthew Pickering2023-02-011-1/+1
| | | | | alpine_3_12 only supports LLVM 10, which is now outside the supported version range.
* Bump supported LLVM range from 10 through 15 to 11 through 16Matthew Pickering2023-02-012-5/+5
| | | | | | | | | | | | | | LLVM 15 turns on the new pass manager by default, which we have yet to migrate to so for new we pass the `-enable-new-pm-0` flag in our llvm-passes flag. LLVM 11 was the first version to support the `-enable-new-pm` flag so we bump the lowest supported version to 11. Our CI jobs are using LLVM 12 so they should continue to work despite this bump to the lower bound. Fixes #21936
* Treat existentials correctly in dubiousDataConInstArgTysSimon Peyton Jones2023-02-013-9/+33
| | | | | | | | | | | | | Consider (#22849) data T a where MkT :: forall k (t::k->*) (ix::k). t ix -> T @k a Then dubiousDataConInstArgTys MkT [Type, Foo] should return [Foo (ix::Type)] NOT [Foo (ix::k)] A bit of an obscure case, but it's an outright bug, and the fix is easy.
* Improve treatment of type applications in patternswip/T19847Simon Peyton Jones2023-02-0111-105/+411
| | | | | | | | | | This patch fixes a subtle bug in the typechecking of type applications in patterns, e.g. f (MkT @Int @a x y) = ... See Note [Type applications in patterns] in GHC.Tc.Gen.Pat. This fixes #19847, #22383, #19577, #21501
* compiler: properly handle non-word-sized CmmSwitch scrutinees in the wasm NCGwip/T21776Cheng Shao2023-01-315-1/+49
| | | | | | | | Currently, the wasm NCG has an implicit assumption: all CmmSwitch scrutinees are 32-bit integers. This is not always true; #22864 is one counter-example with a 64-bit scrutinee. This patch fixes the logic by explicitly converting the scrutinee to a word that can be used as a br_table operand. Fixes #22871. Also includes a regression test.

* hadrian: Substitute LIBRARY_*_VERSION variablesBen Gamari2023-01-312-2/+18
| | | | | | | This teaches Hadrian to substitute the `LIBRARY_*_VERSION` variables in `libraries/prologue.txt`, fixing #22714. Fixes #22714.
* hadrian: Refactor templating logicBen Gamari2023-01-311-61/+90
| | | | | | This refactors Hadrian's autoconf-style templating logic to be explicit about which interpolation variables should be substituted in which files. This clears the way to fix #22714 without incurring rule cycles.
* hadrian: Sphinx docs require templated cabal filesBen Gamari2023-01-311-2/+15
| | | | | | | The package-version discovery logic in `doc/users_guide/package_versions.py` uses packages' cabal files to determine package versions. Teach Sphinx about these dependencies in cases where the cabal files are generated by templates.

* nativeGen/AArch64: Fix graph-colouring allocatorBen Gamari2023-01-311-1/+10
| | | | | | | | Previously various `Instr` queries used by the graph-colouring allocator failed to handle a few pseudo-instructions. This manifested in compiler panicks while compiling `SHA`, which uses `-fregs-graph`. Fixes #22798.
* nativeGen: Teach graph-colouring allocator that x18 is unusableBen Gamari2023-01-311-4/+2
| | | | | | | | Previously trivColourable for AArch64 claimed that at 18 registers were trivially-colourable. This is incorrect as x18 is reserved by the platform on AArch64/Darwin. See #22798.
* nativeGen/AArch64: Fix debugging outputBen Gamari2023-01-311-10/+68
| | | | | | | Previously various panics would rely on a half-written Show instance, leading to very unhelpful errors. Fix this. See #22798.
* Revert "Cmm Lint: relax SIMD register assignment check"sheaf2023-01-311-14/+1
| | | | | | This reverts commit 3be48877, which weakened a Cmm Lint check involving SIMD vectors. Now that we keep track of the type a global register is used at, we can restore the original stronger check.
* Cmm: track the type of global registerssheaf2023-01-3140-617/+671
| | | | | | | | | | | | This patch tracks the type of Cmm global registers. This is needed in order to lint uses of polymorphic registers, such as SIMD vector registers that can be used both for floating-point and integer values. This changes allows us to refactor VanillaReg to not store VGcPtr, as that information is instead stored in the type of the usage of the register. Fixes #22297
* configure: Always create the VERSION fileBen Gamari2023-01-313-7/+4
| | | | | | | | Teach the `configure` script to create the `VERSION` file. This will serve as the stable interface to allow the user to determine the version number of a working tree. Fixes #22322.

* Improve exprOkForSpeculation for classopsSimon Peyton Jones2023-01-3121-80/+228
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes #22745 and #15205, which are about GHC's failure to discard unnecessary superclass selections that yield coercions. See GHC.Core.Utils Note [exprOkForSpeculation and type classes] The main changes are: * Write new Note [NON-BOTTOM_DICTS invariant] in GHC.Core, and refer to it * Define new function isTerminatingType, to identify those guaranteed-terminating dictionary types. * exprOkForSpeculation has a new (very simple) case for ClassOpId * ClassOpId has a new field that says if the return type is an unlifted type, or a terminating type. This was surprisingly tricky to get right. In particular note that unlifted types are not terminating types; you can write an expression of unlifted type, that diverges. Not so for dictionaries (or, more precisely, for the dictionaries that GHC constructs). Metric Decrease: LargeRecord

* User's guide: Clarify overlapping instance candidate eliminationJason Shipman2023-01-301-2/+2
| | | | | | | | | | | | This commit updates the user's guide section on overlapping instance candidate elimination to use "or" verbiage instead of "either/or" in regards to the current pair of candidates' being overlappable or overlapping. "Either IX is overlappable, or IY is overlapping" can cause confusion as it suggests "Either IX is overlappable, or IY is overlapping, but not both". This was initially discussed on this Discourse topic: https://discourse.haskell.org/t/clarification-on-overlapping-instance-candidate-elimination/5677
