Function core::arch::arm::__ssub8

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.

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.
