This begins to attempt to restructure the source tree so that the common parts are common and the different parts are different. The backend is now split into two parts: - serial (containing the implementation using serial formulas and mixed-model arithmetic). - vector (containing the implementation using parallel formulas and single-model arithmetic). The serial scalar_mul tree is now under backend::serial::scalar_mul. The avx2 scalar_mul tree is now under backend::avx2::scalar_mul.

//! The `u64` backend uses `u64`s and a `(u64, u64) -> u128` multiplier.
|
|
//!
|
|
//! On x86_64, the idiom `(x as u128) * (y as u128)` lowers to `MUL`
|
|
//! instructions taking 64-bit inputs and producing 128-bit outputs. On
|
|
//! other platforms, this implementation is not recommended.
|
|
//!
|
|
//! On Haswell and newer, the BMI2 extension provides `MULX`, and on
|
|
//! Broadwell and newer, the ADX extension provides `ADCX` and `ADOX`
|
|
//! (allowing the CPU to compute two carry chains in parallel). These
|
|
//! will be used if available.
