Simon Peyton Jones pushed to branch wip/T26772 at Glasgow Haskell Compiler / GHC Commits: 56db94f7 by Peter Trommler at 2026-01-26T11:26:18+01:00 PPC NCG: Generate clear right insn at arch width The clear right immediate (clrrxi) is only available in word and doubleword width. Generate clrrxi instructions at architecture width for all MachOp widths. Fixes #24145 - - - - - 5957a8ad by Wolfgang Jeltsch at 2026-01-27T06:11:40-05:00 Add operations for obtaining operating-system handles This contribution implements CLC proposal #369. It adds operations for obtaining POSIX file descriptors and Windows handles that underlie Haskell handles. Those operating system handles can also be obtained without such additional operations, but this is more involved and, more importantly, requires using internals. - - - - - 86a0510c by Greg Steuck at 2026-01-27T06:12:34-05:00 Move flags to precede patterns for grep and read files directly This makes the tests pass with non-GNU (i.e. POSIX-complicant) tools. There's no reason to use cat and pipe where direct file argument works. - - - - - efa4b101 by Simon Peyton Jones at 2026-01-27T16:56:38+00:00 Fix subtle bug in GHC.Core.Utils.mkTick ..Proper commit message still to come... - - - - - a4f9eb90 by Simon Peyton Jones at 2026-01-27T16:56:38+00:00 Modify the debug-trace a little - - - - - 575a61a9 by Simon Peyton Jones at 2026-01-27T16:56:38+00:00 Fix long-standing interaction between ticks and casts The code for Note [Eliminate Identity Cases] was simply wrong when ticks and casts interacted. This patch fixes the interaction. It was shown up when validating #26772, although it's not the exactly the bug that's reported by #26772. Nor is it easy to reproduce, hence no regression test. - - - - - 31 changed files: - compiler/GHC/CmmToAsm/PPC/CodeGen.hs - compiler/GHC/Core/Opt/Simplify/Iteration.hs - compiler/GHC/Core/Opt/Simplify/Utils.hs - compiler/GHC/Core/Utils.hs - compiler/GHC/Tc/Instance/Class.hs - compiler/GHC/Tc/Types/Evidence.hs - libraries/base/base.cabal.in - libraries/base/changelog.md - + libraries/base/src/System/IO/OS.hs - libraries/base/tests/IO/all.T - + libraries/base/tests/IO/osHandles001FileDescriptors.hs - + libraries/base/tests/IO/osHandles001FileDescriptors.stdout - + libraries/base/tests/IO/osHandles001WindowsHandles.hs - + libraries/base/tests/IO/osHandles001WindowsHandles.stdout - + libraries/base/tests/IO/osHandles002FileDescriptors.hs - + libraries/base/tests/IO/osHandles002FileDescriptors.stderr - + libraries/base/tests/IO/osHandles002FileDescriptors.stdin - + libraries/base/tests/IO/osHandles002FileDescriptors.stdout - + libraries/base/tests/IO/osHandles002WindowsHandles.hs - + libraries/base/tests/IO/osHandles002WindowsHandles.stderr - + libraries/base/tests/IO/osHandles002WindowsHandles.stdin - + libraries/base/tests/IO/osHandles002WindowsHandles.stdout - libraries/base/tests/perf/Makefile - libraries/ghc-internal/ghc-internal.cabal.in - + libraries/ghc-internal/src/GHC/Internal/System/IO/OS.hs - testsuite/tests/driver/T16318/Makefile - testsuite/tests/driver/T18125/Makefile - 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 The diff was not included because it is too large.
