VLDM (floating-point)

11.11 VLDM (floating-point)

Extension register load multiple.

Syntax

VLDMmode{cond} Rn{!}, Registers
where:
mode
must be one of:
IA
meaning Increment address After each transfer. IA is the default, and can be omitted.
DB
meaning Decrement address Before each transfer.
EA
meaning Empty Ascending stack operation. This is the same as DB for loads.
FD
meaning Full Descending stack operation. This is the same as IA for loads.
cond
is an optional condition code.
Rn
is the ARM register holding the base address for the transfer.
!
is optional. ! specifies that the updated base address must be written back to Rn. If ! is not specified, mode must be IA.
Registers
is a list of consecutive extension registers enclosed in braces, { and }. The list can be comma-separated, or in range format. There must be at least one register in the list.
You can specify S or D registers, but they must not be mixed. The number of registers must not exceed 16 D registers.

Note

VPOP Registers is equivalent to VLDM sp!, Registers.
You can use either form of this instruction. They both disassemble to VPOP.
