[−][src]Macro safe_arch::extract_i16_as_i32_m256i

macro_rules! extract_i16_as_i32_m256i {
    ($a:expr, $imm:expr) => { ... };
}
This is supported with target feature avx2 only.

Gets an i16 value out of an m256i, returns as i32.

The lane to get must be a constant. If you select outside the range 0..16 then the selection is wrapped to be in range (only the lowest 4 bits of the input are used).

let a =
  m256i::from([0xA_i16, 0xB, 0xC, 0xD, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]);
//
assert_eq!(extract_i16_as_i32_m256i!(a, 0), 0xA);
assert_eq!(extract_i16_as_i32_m256i!(a, 1), 0xB);
// the lane requested is "wrapped" to be a valid index.
assert_eq!(0b1_0010 & 0b1111, 2);
assert_eq!(extract_i16_as_i32_m256i!(a, 0b1_0010), 0xC);
