VADD (Vector Add) adds corresponding elements
in two vectors, and places the results in the destination vector.
VSUB (Vector Subtract) subtracts the elements
of one vector from the corresponding elements of another vector,
and places the results in the destination vector.
VADD and VSUB have these forms:
Saturating. The sticky QC flag (FPSCR bit[27]) is set if saturation occurs.
Long.
Wide.
Syntax
V{Q}op{cond}.datatype {Qd}, Qn, Qm ; Saturating instruction
V{Q}op{cond}.datatype {Dd}, Dn, Dm ; Saturating instruction
VopL{cond}.datatypeQd,Dn,Dm; Long instruction
VopW{cond}.datatype{Qd},Qn,Dm; Wide instruction
where:
Qif present, indicates that if any of the results overflow, they are saturated.
opmust be either
