Sounds like you are looking at redundant extension problem in RISC-V port.
This is the issue I want to fix but I don't find the time to do that.
My first impression is that we need to fix redundant extension in "ree" PASS.
I am not sure.
Base on you are looking at this kind of issues, would you mind looking at this issue?
