If all inputs to an fmadds instruction (including cousins like fmsubs, fnmadd...) are single-precision, then the result is identical between a double-precision calculation with an error-free transform (whether the calculation is fused or not) and a single-precision FMA instruction (must be fused). So as a performance optimization in JitArm64, if we were going to use double precision with EFT but the inputs are singles, instead we'll use a normal single-precision FMA instruction without anything extra. This lets us skip both the EFT and double-to-single conversions. Also renaming `inaccurate_fma` to `nonfused` because it's confusing that `inaccurate_fma` and `m_accurate_fmadds` have such similar names despite controlling separate things. |
