friend constexpr basic_simd& operator+=(basic_simd& lhs, const basic_simd& rhs) noexcept;
friend constexpr basic_simd& operator-=(basic_simd& lhs, const basic_simd& rhs) noexcept;
friend constexpr basic_simd& operator*=(basic_simd& lhs, const basic_simd& rhs) noexcept;
friend constexpr basic_simd& operator/=(basic_simd& lhs, const basic_simd& rhs) noexcept;
friend constexpr basic_simd& operator%=(basic_simd& lhs, const basic_simd& rhs) noexcept;
friend constexpr basic_simd& operator&=(basic_simd& lhs, const basic_simd& rhs) noexcept;
friend constexpr basic_simd& operator|=(basic_simd& lhs, const basic_simd& rhs) noexcept;
friend constexpr basic_simd& operator^=(basic_simd& lhs, const basic_simd& rhs) noexcept;
friend constexpr basic_simd& operator<<=(basic_simd& lhs, const basic_simd& rhs) noexcept;
friend constexpr basic_simd& operator>>=(basic_simd& lhs, const basic_simd& rhs) noexcept;

Let op be the operator.

Constraints: requires (value_type a, value_type b) { a op b; } is true.

Effects: These operators apply the indicated operator to lhs and rhs as an element-wise operation.

Returns: lhs.

friend constexpr basic_simd& operator<<=(basic_simd& lhs, simd-size-type n) noexcept;
friend constexpr basic_simd& operator>>=(basic_simd& lhs, simd-size-type n) noexcept;

Let op be the operator.

Constraints: requires (value_type a, simd-size-type b) { a op b; } is true.

Effects: Equivalent to: return operator op (lhs, basic_simd(n));
