Marge Bot pushed to branch master at Glasgow Haskell Compiler / GHC Commits: 9995c2b7 by Serge S. Gulin at 2025-05-04T17:13:36+03:00 Support for ARM64 Windows (LLVM-enabled) (fixes #24603) 1. Add Windows AArch64 cross-compilation support via CI jobs Introduce new CI configurations for cross-compiling to Windows ARM64 using Debian12Wine, FEX, and MSYS2. Configure toolchain variables for LLVM MinGW and Wine emulation in CI pipelines. 2. Adjust compiler and RTS for AArch64 Windows compatibility Reserve register `x18` on Windows and Darwin platforms in AArch64 codegen. Handle Windows-specific relocations and data sections in AArch64 assembler. Update PEi386 linker to recognize ARM64 binaries and support exception handling. Adjust LLVM target definitions and data layouts for new architectures. Update `ghc-toolchain` and build scripts to handle `TablesNextToCode` on Windows ARM64. 3. Enhance CI scripts and stability Modify `ci.sh` to handle mingw cross-targets, fixing GHC executable paths and test execution. Use `diff -w` in tests to ignore whitespace differences, improving cross-platform consistency. 4. Refactor and clean up code Remove redundant imports in hello.hs test. Improve error messages and checks for unsupported configurations in the driver. Add `EXDEV` error code to `errno.js`. Add async/sync flags to IO logs at `base.js`. Improve POSIX compatibility for file close at `base.js`: decrease indeterminism for mixed cases of async and sync code. 5. Update dependencies: `Cabal`, `Win32`, `directory`, `process`, `haskeline`, and `unix`. submodule Co-authored-by: Cheng Shao Co-authored-by: Dmitrii Egorov Co-authored-by: Andrei Borzenkov - - - - - 37 changed files: - .gitlab-ci.yml - .gitlab/ci.sh - .gitlab/generate-ci/gen_ci.hs - .gitlab/hello.hs - .gitlab/jobs.yaml - compiler/CodeGen.Platform.h - compiler/GHC/CmmToAsm/AArch64/CodeGen.hs - compiler/GHC/CmmToAsm/AArch64/Instr.hs - compiler/GHC/CmmToAsm/AArch64/Ppr.hs - compiler/GHC/CmmToAsm/Reg/Linear/AArch64.hs - compiler/GHC/Driver/Session.hs - compiler/GHC/Platform/Regs.hs - hadrian/src/Oracles/Setting.hs - hadrian/src/Rules/BinaryDist.hs - libraries/Cabal - libraries/Win32 - libraries/base/src/System/CPUTime/Windows.hsc - libraries/base/tests/perf/encodingAllocations.hs - libraries/directory - libraries/ghc-internal/jsbits/base.js - libraries/ghc-internal/jsbits/errno.js - libraries/ghc-internal/src/GHC/Internal/System/Posix/Internals.hs - libraries/haskeline - libraries/process - libraries/unix - llvm-targets - m4/fp_cc_supports_target.m4 - m4/fptools_set_platform_vars.m4 - m4/ghc_tables_next_to_code.m4 - rts/StgCRun.c - rts/linker/PEi386.c - rts/win32/veh_excn.c - testsuite/tests/ghc-api/fixed-nodes/all.T - testsuite/tests/interface-stability/base-exports.stdout-javascript-unknown-ghcjs - utils/ghc-toolchain/exe/Main.hs - utils/hsc2hs - utils/llvm-targets/gen-data-layout.sh The diff was not included because it is too large.
