VLDn (single n-element structure to all lanes)

Vector Load single n-element structure to all lanes.


VLDn{cond}.datatype list, [Rn{@align}]{!}

VLDn{cond}.datatype list, [Rn{@align}], Rm



must be one of 1, 2, 3, or 4.


is an optional condition code.


see the following table.


is the list of Advanced SIMD registers enclosed in braces, { and }. See the following table for options.


is the ARM register containing the base address. Rn cannot be PC.


specifies an optional alignment. See the following table for options.


if ! is present, Rn is updated to (Rn + the number of bytes transferred by the instruction). The update occurs after all the loads have taken place.


is an ARM register containing an offset from the base address. If Rm is present, the instruction updates Rn to (Rn + Rm) after using the address to access memory. Rm cannot be SP or PC.


VLDn loads multiple copies of one n-element structure from memory into one or more Advanced SIMD registers.

Every register in the list must be in the range D0-D31.


align can be omitted. In this case, standard alignment rules apply.
