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 general-purpose 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 a general-purpose 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.
