Issues with XuanTie Cseries instruction manual #3

I want to report issues with descriptions (syntax and opcodes) in these chapters:

5.33 LURWU: a load word instruction that shifts 32 bits of registers and
extends zero bits.

5.34 LWD: a load word instruction that loads double registers and extends signed bits.

LLVM disassembler shows one extra operand for:

lwd t1, t2, (t3), 2, 3
lwud t1, t2, (t3), 2, 3
ldd t1, t2, (t3), 2, 4
swd t1, t2, (t3), 2, 3
sdd t1, t2, (t3), 2, 4

instructions. Is it OK?
