lxvx

Load VSX Vector Indexed X-form

lxvx XT,RA,RB

Loads a quadword from memory into a VSX register.

Details

Loads a 128-bit quadword from memory into a VSX register using indexed addressing. The effective address is computed as RA|0 + RB. No status fields are modified by this instruction.

Pseudocode Operation

EA ← (RA=0 ? 0 : GPR[RA]) + GPR[RB]
VSR[XT] ← MEM(EA, 16)

Programming Note

The lxvx instruction is used to load vector data from memory into VSX registers.
