ARM Compiler armasm User Guide : VORR (register)

VORR (register)

Vector bitwise OR (register).

Syntax

VORR{cond}{.datatype} {Qd}, Qn, Qm

VORR{cond}{.datatype} {Dd}, Dn, Dm

where:

cond

is an optional condition code.

datatype

is an optional data type. The assembler ignores datatype.

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.

Note

VORR with the same register for both operands is a VMOV instruction. You can use VORR in this way, but disassembly of the resulting code produces the VMOV syntax.

Operation

VORR performs a bitwise logical OR between two registers, and places the result in the destination register.
