Heliumuint32x4_t[__arm_]vsbciq_m[_u32](uint32x4_t inactive, uint32x4_t a, uint32x4_t b, unsigned * carry_out, mve_pred16_t p)Vector arithmetic / Subtract / Subtraction
Description
Beat-wise subtracts the value of the elements in the second source vector register and the value of NOT(Carry flag) from the respective elements in the first source vector register, the carry flag being FPSCR.C. The initial value of FPSCR.C can be overridden by using the 'I' variant. FPSCR.C is not updated for beats disabled due to predication. FPSCR.N, .V and .Z are zeroed.
