Wolfgang Jeltsch pushed to branch wip/jeltsch/text-read-implementation-into-base at Glasgow Haskell Compiler / GHC Commits: cc9cc6d5 by Cheng Shao at 2026-04-23T09:40:46+00:00 configure: bump LlvmMaxVersion to 23 This patch bumps `LlvmMaxVersion` to 23 to support LLVM 22.x releases. - - - - - 2ea7ef8e by Cheng Shao at 2026-04-23T09:46:26+00:00 changelog: add llvm 22.x support - - - - - 5574ee10 by Cheng Shao at 2026-04-24T08:24:30-04:00 compiler: avoid unused temporary `appendFS` operands This patch fixes unused temporary `appendFS` operands in the codebase that are retained in the `FastString` table after concatenation. Rewrite rules are added so that if an operand is `fsLit`/`mkFastString`, the `appendFS` application is rewritten to append the `ShortByteString` operands first. The patch also fixes `sconcat` behavior to align with `mconcat` for the same reason. Fixes #27205. - - - - - 4ed78760 by mangoiv at 2026-04-24T08:25:13-04:00 contributing: adjust MR template to be less verbose - MR template only shows text that is relevant for submissiong - MR template was rewritten so it's readable from a user's and reviewer's perspective Resolves #27165 Co-Authored-By: @sheaf - - - - - 87db83e2 by Cheng Shao at 2026-04-24T14:37:21-04:00 ci: bump freebsd boot ghc to 9.10.3 This commit bumps freebsd boot ghc to 9.10.3 to align with other platforms and prevent outdated boot libs in boot ghc to block the freebsd job. - - - - - 17e3a0b7 by Cheng Shao at 2026-04-24T14:37:21-04:00 compiler: improve Binary instance of Array This patch improves the `Binary` instance of `Array`: - We no longer allocate intermediate lists. When serializing an `Array`, we iterate over the elements directly; when deserializing it, we allocate the result `Array` and fill it in a loop. - Now we only serialize the array bounds tuple; the length field is not needed. Closes #27109. - - - - - 2d30f7d3 by sheaf at 2026-04-24T14:38:23-04:00 Vendor mini-QuickCheck for testsuite This commit extracts the vendored QuickCheck implementation from the foundation testsuite to make it more broadly available in the GHC testsuite, and makes use of it in the simd006 test (which also used a vendored QuickCheck implementation). On the way, we update the linear congruential generator to avoid the shortcoming of only generating 31 bit large numbers. Fixes #25990 and #25969. - - - - - a3786627 by Wolfgang Jeltsch at 2026-04-25T15:22:55+03:00 Move code that uses `GHC.Internal.Text.Read` into `base` This contribution serves to remove all dependencies on `GHC.Internal.Text.Read` from within `ghc-internal`, so that the implementation of `Text.Read` and ultimately more reading-related code can be moved to `base` as well. The following things are moved from `ghc-internal` to `base`: * I/O-related `Read` instances * Most of the `Numeric` implementation * The instance `Read ByteOrder` * The `parseVersion` operation * The `readConstr` operation Metric Increase: LinkableUsage01 T12425 T13035 - - - - - ae2be0b0 by Wolfgang Jeltsch at 2026-04-25T15:23:26+03:00 Move the `Text.Read` implementation into `base` - - - - - 41 changed files: - .gitlab/generate-ci/gen_ci.hs - .gitlab/jobs.yaml - .gitlab/merge_request_templates/Default.md - + changelog.d/binary-array-no-list - + changelog.d/llvm-22 - compiler/GHC/Data/FastString.hs - compiler/GHC/Utils/Binary.hs - configure.ac - libraries/base/src/Data/Data.hs - libraries/base/src/Data/Functor/Classes.hs - libraries/base/src/Data/Functor/Compose.hs - libraries/base/src/Data/Version.hs - libraries/base/src/GHC/ByteOrder.hs - libraries/base/src/Numeric.hs - libraries/base/src/Prelude.hs - libraries/base/src/System/IO.hs - libraries/base/src/Text/Printf.hs - libraries/base/src/Text/Read.hs - libraries/ghc-internal/ghc-internal.cabal.in - libraries/ghc-internal/src/GHC/Internal/Data/Data.hs - libraries/ghc-internal/src/GHC/Internal/Data/Version.hs - libraries/ghc-internal/src/GHC/Internal/IO/Device.hs - libraries/ghc-internal/src/GHC/Internal/IO/Handle/Types.hs - libraries/ghc-internal/src/GHC/Internal/IO/IOMode.hs - libraries/ghc-internal/src/GHC/Internal/Numeric.hs - libraries/ghc-internal/src/GHC/Internal/Read.hs - − libraries/ghc-internal/src/GHC/Internal/Text/Read.hs - testsuite/driver/testlib.py - + testsuite/tests/MiniQuickCheck.hs - 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/numeric/should_run/all.T - testsuite/tests/numeric/should_run/foundation.hs - testsuite/tests/plugins/plugins09.stdout - testsuite/tests/plugins/plugins10.stdout - testsuite/tests/plugins/plugins11.stdout - testsuite/tests/plugins/static-plugins.stdout - testsuite/tests/simd/should_run/all.T - testsuite/tests/simd/should_run/simd006.hs The diff was not included because it is too large.
