    pub fn _mm_set_ps(a: f32, b: f32, c: f32, d: f32) -> __m128

Available on (x86 or x86-64) and target feature `sse` and x86-64 only.
Expand description

Construct a `__m128` from four floating point values highest to lowest.

Note that `a` will be the highest 32 bits of the result, and `d` the lowest. This matches the standard way of writing bit patterns on x86:

     bit    127 .. 96  95 .. 64  63 .. 32  31 .. 0
           +---------+---------+---------+---------+
           |    a    |    b    |    c    |    d    |   result
           +---------+---------+---------+---------+

Alternatively:

    let v = _mm_set_ps(d, c, b, a);
