Expand description

128-bit wide set of four `f32` values, LoongArch-specific

This type is the same as the `__m128` type defined in `lsxintrin.h`, representing a 128-bit SIMD register which internally consists of four packed `f32` instances. Usage of this type typically occurs in conjunction with the `lsx` and higher target features for LoongArch.

Note that unlike `m128i`, the integer version of the 128-bit registers, this `m128` type has one interpretation. Each instance of `m128` corresponds to `f32x4`, or four `f32` values packed together.

The in-memory representation of this type is the same as the one of an equivalent array (i.e. the in-memory order of elements is the same, and there is no padding); however, the alignment is different and equal to the size of the type. Note that the ABI for function calls may not be the same.

Most intrinsics using `m128` are prefixed with `lsx_` and are suffixed with “s”.
