Peter Trommler pushed to branch wip/T26521 at Glasgow Haskell Compiler / GHC Commits: 6ef22fa0 by IC Rainbow at 2025-10-26T18:23:01-04:00 Add SIMD primops for bitwise logical operations This adds 128-bit wide and/or/xor instructions for X86 NCG, with both SSE and AVX encodings. ``` andFloatX4# :: FloatX4# -> FloatX4# -> FloatX4# -- andps / vandps andDoubleX2# :: DoubleX2# -> DoubleX2# -> DoubleX2# -- andpd / vandpd andInt8X16# :: Int8X16# -> Int8X16# -> Int8X16# -- pand / vpand ``` The new primops are available on ARM when using LLVM backend. Tests added: - simd015 (floats and doubles) - simd016 (integers) - simd017 (words) Fixes #26417 - - - - - fbdc623a by sheaf at 2025-10-26T18:23:52-04:00 Add hints for unsolved HasField constraints This commit adds hints and explanations for unsolved 'HasField' constraints. GHC will now provide additional explanations for an unsolved constraint of the form 'HasField fld_name rec_ty fld_ty'; the details are laid out in Note [Error messages for unsolved HasField constraints], but briefly: 1. Provide similar name suggestions (e.g. mis-spelled field name) and import suggestions (record field not in scope). These result in actionable 'GhcHints', which is helpful to provide code actions in HLS. 2. Explain why GHC did not solve the constraint, e.g.: - 'fld_name' is not a string literal (e.g. a type variable) - 'rec_ty' is a TyCon without any fields, e.g. 'Int' or 'Bool'. - 'fld_ty' contains existentials variables or foralls. - The record field is a pattern synonym field (GHC does not generate HasField instances for those). - 'HasField' is a custom 'TyCon', not actually the built-in 'HasField' typeclass from 'GHC.Records'. On the way, we slightly refactor the mechanisms for import suggestions in GHC.Rename.Unbound. This is to account for the fact that, for 'HasField', we don't care whether the field is imported qualified or unqualified. 'importSuggestions' was refactored, we now have 'sameQualImportSuggestions' and 'anyQualImportSuggestions'.
