MOVT (scalar to ZT0)

Move 8 bytes to the ZT0 register at the byte offset specified by the immediate index from a general-purpose register. This instruction is UNDEFINED in Non-debug state.

SME2
(FEAT_SME2)

if !HaveSME2() || !Halted() then UNDEFINED; integer t = UInt(Rt); integer offset = UInt(off3);

Assembler Symbols

<offs>

Is the immediate byte offset, a multiple of 8 in the range of 0 to 56, encoded in the "off3" field as <offs>/8.

<Xt>	Is the 64-bit name of the general-purpose register to be transferred, encoded in the "Rt" field.

Operation

CheckSMEEnabled(); CheckSMEZT0Enabled(); bits(512) result = ZT0[512]; Elem[result, offset, 64] = X[t, 64]; ZT0[512] = result;

Operational information

If PSTATE.DIT is 1:

The execution time of this instruction is independent of:
- The values of the data supplied in any of its registers.
- The values of the NZCV flags.
The response of this instruction to asynchronous exceptions does not vary based on:
- The values of the data supplied in any of its registers.
- The values of the NZCV flags.
