c.ld

Loads a 64-bit value from memory into register xd. It computes an effective address by adding the zero-extended offset, scaled by 8, to the base address in register xs1. It expands to `ld` `xd, offset(xs1)`. For RV32, if the Zclsd extension is enabled, this instruction loads a 64-bit value into registers xd and xd+1. It computes an effective address by adding the zero-extended imm, scaled by 8, to the base address in register xs1.

c.ld xd, imm(xs1)
