VSTR

Extension register store.

Syntax

VSTR{cond}{.64} Dd, [Rn{, #offset}]

where:

cond

is an optional condition code.

Dd

is the extension register to be saved.

Rn

is the general-purpose register holding the base address for the transfer.

offset

is an optional numeric expression. It must evaluate to a numeric value at assembly time. The value must be a multiple of 4, and lie in the range -1020 to +1020. The value is added to the base address to form the address used for the transfer.
