            Bug ID: 30512
           Summary: objdump 2.40 for risc-v doesn't have "addi"
                    instruction
           Product: binutils
           Version: 2.40
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

binutils 2.39 vs 2.40 <objdump -D> of the same ELF

I have noticed the objdump for risc-v calls the "addi" instruction "add", and
doesn't generates the "addi" instruction at all.
I looked at the op code at it matches the "addi" instruction but in the dump
it's named "add", and also the third argument is a number and not a register.
Same for shift instructions.
In binutils 2.39 it doesn't seem to happen.

Might not be a bug, since it's pretty clear the the third argument is an
immediate, but I think these two different instructions should have different
names in the dump as well.
