pub unsafe fn __ssub8(a: int8x4_t, b: int8x4_t) -> int8x4_t🔬This is a nightly-only experimental API. (
stdsimd #48556)Available on ARM only.
Expand description
Inserts a SSUB8 instruction.
Returns the 8-bit signed equivalent of
res[0] = a[0] - a[0] res[1] = a[1] - a[1] res[2] = a[2] - a[2] res[3] = a[3] - a[3]
where [0] is the lower 8 bits and [3] is the upper 8 bits. The GE bits of the APSR are set.
