Re: Signed v Unsigned Immediate: vsaddu.vi

The non-normative text you quoted should be edited to delete the words “it is signed”.
The immediate is sign-extended, but then is treated as an unsigned value. So the operation doesn’t differ based on the argument type.
(This sign-extended-but-unsigned-immediate pattern is also exists for e.g. sltiu in the base ISA and vmsgtu.vi in the vector extension.)
