Andreas Klebinger pushed to branch wip/andreask/split-driver-main at Glasgow Haskell Compiler / GHC Commits: 72d6dc74 by aparker at 2026-04-20T20:15:44-04:00 NCG: Implement constant folding for vector simd ops (Issue #25030) - - - - - b9cab907 by sheaf at 2026-04-20T20:15:44-04:00 Mark some SIMD tests as broken on i386 optllvm As seen in #25498, several SIMD tests are broken on i386 in the optllvm way. This commit marks them as "expect_broken". - - - - - 76528cc3 by Wolfgang Jeltsch at 2026-04-20T20:16:25-04:00 Move most of the `System.IO` implementation into `base` This involves a rewrite of the `combine` helper function to avoid the use of `last`, which would now be flagged as an error.

This commit splits GHC.Driver.Main into four components: * GHC.Driver.Main.Compile * GHC.Driver.Main.Hsc * GHC.Driver.Main.Interactive * GHC.Driver.Main.Passes We might improve that separation further in the future but this should hopefully make it easier to reason about and work with this part of the code. - - - - - 73 changed files: - + changelog.d/fix-finalizers-27072 - + changelog.d/simd_constant_folding - compiler/GHC/Cmm/Opt.hs - compiler/GHC/Driver/Backpack.hs - compiler/GHC/Driver/CodeOutput.hs - compiler/GHC/Driver/Env/Types.hs - compiler/GHC/Driver/Main.hs - + compiler/GHC/Driver/Main/Compile.hs - compiler/GHC/Driver/Main.hs-boot → compiler/GHC/Driver/Main/Compile.hs-boot - + compiler/GHC/Driver/Main/Hsc.hs - + compiler/GHC/Driver/Main/Interactive.hs - + compiler/GHC/Driver/Main/Passes.hs - + compiler/GHC/Driver/Main/Passes.hs-boot - compiler/GHC/Iface/Load.hs - compiler/GHC/Linker/Executable.hs - compiler/GHC/Types/Error.hs - compiler/GHC/Types/Error.hs-boot - compiler/GHC/Types/ForeignStubs.hs - compiler/GHC/Utils/Misc.hs - compiler/ghc.cabal.in - libraries/base/src/Control/Concurrent.hs - libraries/base/src/GHC/IO/Handle.hs - libraries/base/src/Prelude.hs - libraries/base/src/System/IO.hs - libraries/base/src/Text/Printf.hs - libraries/ghc-internal/src/GHC/Internal/System/IO.hs - rts/Linker.c - rts/LinkerInternals.h - rts/linker/Elf.c - + testsuite/tests/codeGen/should_run/T27072d.hs - + testsuite/tests/codeGen/should_run/T27072d.stdout - + testsuite/tests/codeGen/should_run/T27072d_c.c - + testsuite/tests/codeGen/should_run/T27072d_check.c - + testsuite/tests/codeGen/should_run/T27072w.hs - + testsuite/tests/codeGen/should_run/T27072w.stdout - + testsuite/tests/codeGen/should_run/T27072w_c.c - testsuite/tests/codeGen/should_run/all.T - + testsuite/tests/driver/T10531/A.hs - + testsuite/tests/driver/T10531/B.hs - + testsuite/tests/driver/T10531/C.hs - + testsuite/tests/driver/T10531/Makefile - + testsuite/tests/driver/T10531/all.T - testsuite/tests/interface-stability/base-exports.stdout - testsuite/tests/interface-stability/base-exports.stdout-javascript-unknown-ghcjs - testsuite/tests/interface-stability/base-exports.stdout-mingw32 - testsuite/tests/interface-stability/base-exports.stdout-ws-32 - + testsuite/tests/rts/linker/T27072/Lib.c - + testsuite/tests/rts/linker/T27072/Makefile - + testsuite/tests/rts/linker/T27072/T27072.stdout - + testsuite/tests/rts/linker/T27072/all.T - + testsuite/tests/rts/linker/T27072/main.c - + testsuite/tests/simd/should_run/Makefile - + testsuite/tests/simd/should_run/T25030.hs - + testsuite/tests/simd/should_run/T25030.stdout - testsuite/tests/simd/should_run/all.T - testsuite/tests/th/all.T - testsuite/tests/typecheck/should_compile/T9497a.stderr - testsuite/tests/typecheck/should_compile/holes.stderr - testsuite/tests/typecheck/should_compile/holes3.stderr - testsuite/tests/typecheck/should_compile/valid_hole_fits.stderr - testsuite/tests/typecheck/should_fail/T9497d.stderr - testsuite/tests/typecheck/should_run/T9497a-run.stderr - testsuite/tests/typecheck/should_run/T9497b-run.stderr - testsuite/tests/typecheck/should_run/T9497c-run.stderr - utils/haddock/html-test/ref/Bug1004.html - utils/haddock/html-test/ref/Bug973.html - utils/haddock/html-test/ref/ConstructorPatternExport.html - utils/haddock/html-test/ref/DefaultSignatures.html - utils/haddock/html-test/ref/Hash.html - utils/haddock/html-test/ref/PatternSyns.html - utils/haddock/html-test/ref/PatternSyns2.html - utils/haddock/html-test/ref/QuasiExpr.html - utils/haddock/html-test/ref/Test.html The diff was not included because it is too large.
