VMAX and VMIN
Vector Maximum, Vector Minimum.
Syntax
V{opconddatatypeQdQnQm
V{opconddatatypeDdDnDm
where:
opmust be either
MAXorMIN.condis an optional condition code.
datatypemust be one of
S8,S16,S32,U8,U16,U32, orF32.Qd,Qn,Qmare the destination vector, the first operand vector, and the second operand vector, for a quadword operation.
Dd,Dn,Dmare the destination vector, the first operand vector, and the second operand vector, for a doubleword operation.
Operation
VMAX compares corresponding elements in two vectors, and copies the larger
of each pair into the corresponding element in the destination vector.
VMIN compares corresponding elements in two vectors, and copies the
smaller of each pair into the corresponding element in the destination vector.
Floating-point maximum and minimum
max(+0.0, –0.0) = +0.0.
min(+0.0, –0.0) = –0.0
If any input is a NaN, the corresponding result element is the default NaN.
