Function core::arch::arm::__usub8

pub unsafe fn __usub8(a: uint8x4_t, b: uint8x4_t) -> uint8x4_t

🔬 This is a nightly-only experimental API. (stdsimd #48556)

This is supported on ARM only.

Inserts a USUB8 instruction.

Returns the 8-bit unsigned 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.
