VMOV{cond} Sm, Sm1, Rd, Rn

VMOV{cond} Rd, Rn, Sm, Sm1

where:

cond

is an optional condition code.

Dm

is a 64-bit extension register.

Sm

is a VFP 32-bit register.

Sm1

is the next consecutive VFP 32-bit register after Sm.

Rd, Rn

are the ARM registers. Rd and Rn must not be PC.

Operation

VMOV Dm, Rd, Rn transfers the contents of Rd into the low half of Dm, and the contents of Rn into the high half of Dm.

VMOV Rd, Rn, Dm transfers the contents of the low half of Dm into Rd, and the contents of the high half of Dm into Rn.

VMOV Rd, Rn, Sm, Sm1 transfers the contents of Sm into Rd, and the contents of Sm1 into Rn.
