where:
op
must be one of:
GE
Absolute Greater than or Equal.
GT
Absolute Greater Than.
LE
Absolute Less than or Equal.
LT
Absolute Less Than.
cond
is an optional condition code.
Qd
,Qn
,Qm
specifies the destination register, the first operand register, and the second operand register, for a quadword operation.
Dd
,Dn
,Dm
specifies the destination register, the first operand register, and the second operand register, for a doubleword operation.
The result datatype is I32
.
Operation
These instructions take the absolute value of each element in a vector, and compare it with the absolute value of the corresponding element of a second vector. If the condition is true, the corresponding element in the destination vector is set to all ones. Otherwise, it is set to all zeros.
Note
On disassembly, the VACLE
and VACLT
pseudo-instructions
are disassembled to the corresponding VACGE
and VACGT
instructions, with the operands reversed.
