VSEL
Floating-point select.
Note
This instruction is supported only in ARMv8.Syntax
VSELcondSdSnSm
VSELcondDdDnDm
where:
cond- must be one of GE, GT, EQ, VS.
Sd,Sn,Sm- are the single-precision registers for the result and operands.
Dd,Dn,Dm- are the double-precision registers for the result and operands.
Usage
The VSEL instruction compares the
values in the operand registers. If the condition is true, it copies
the value in the first operand register into the destination operand
register. Otherwise, it copies the value in the second operand register.
You cannot use VSEL inside an IT
block.
Floating-point exceptions
VSEL instructions cannot produce
any exceptions.
