0ceaaa27c4- a * b + c is two roundings on every processor and --cpu: the IR has no fast-math flags, and clang compiles it with -ffp-contract=on (checked in the assembly: never fused, also with FMA hardware) - fma(a, b, c) / v.fma(b, c): one rounding, always (llvm.fma) - muladd(a, b, c) / v.muladd(b, c): the fastest way here (llvm.fmuladd), what v.fma was before - f32_bits / f32_from_bits / f64_bits / f64_from_bits: bitcasts, also of vectors - f16_to_f32 / f32_to_f16 (LLVM half), bf16_to_f32 / f32_to_bf16 (integer ops, ties to even, NaN kept) - docs (en, pl): what is guaranteed about floats, the new built-ins Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Psc42moPLwP43Cmb9oZqSR |
