Simon Jakobi pushed to branch wip/sjakobi/21176-integer-bits at Glasgow Haskell Compiler / GHC Commits: 5f97e000 by Simon Jakobi at 2026-06-24T11:13:27+02:00 Add explicit setBit/clearBit/complementBit for instance Bits Integer (#21176) The default setBit, clearBit, and complementBit methods allocate intermediate Integers per call. Define them explicitly via the new integerSetBit[#], integerClearBit[#] and integerComplementBit[#], built on the BigNat# primitives, which avoid those allocations. Allocation is not eliminated entirely -- the negative (IN) cases would need in-place mutation, which is left as future work. The default methods constant-folded on literal arguments via the integerOr/integerAnd/integerXor rules, which fold literal Integers of any size. The explicit functions have no such rule, so they (their Word-argument wrappers, and the Bits Integer methods) are marked INLINE to expose the underlying primops to the simplifier; see Note [INLINE for constant folding of bit operations]. This restores folding only on the small-int (IS) path -- large literal Integers (IP/IN) are no longer constant-folded, a minor regression for that case. T8832 covers the IS-path folding. The new golden-output test T21176 checks all three operations against the default implementations across the sign/size boundaries, recording each result plus its integerCheck validity. The base and ghc-bignum interface- stability export goldens gain the new functions. The main changelog entry lives in changelog.d under a new ghc-internal section (renamed from ghc-prim).
