10.6.5 Data Transfer Instructions (between Stack and Register)
Types and functions of extended instructions
These extended instructions allow you to directly specify a displacement of up to 32 bits. Specification of imm32
can be omitted.
Basic instructions after expansion
Expansion formats
(1) Byte data transfer (xld.b, xld.ub)
(2) Half word data transfer (xld.h, xld.uh)
(3) Word data transfer (xld.w)
(4) Word data transfer using SP as the source (xld.w [%sp+imm32], %sp)

If imm32 is omitted, the ext33 assumes that [%sp+0x0] is specified as it expands the instruction.
Example: xld.b %rd, [%sp+imm32]
Example: xld.h %rd, [%sp+imm32]
Example: xld.w %rd, [%sp+imm32]
