Zce Branch: BEQI and BNEI wrong encoding

[abukharmeh]

Hi

It appears that BEQI and BNEI are encoded as they were in 0.40.1. In release 0.50.1, we compare against rs2 instead of rs1, and the immediate location was swapped around

This was changed in this commit, riscvarchive/riscv-code-size-reduction@4838a09

Could you please update this to match 0.50.1

Thank you,
Ibrahim

Hi, we have updated the repo to fix the encoding for beqi and bnei. Also we have added a mi pass to improve instruction compressing. Changes on branch riscv-zce-extension have also been cherry-picked to riscv-zce-llvm14. So it is suggested to try the branch riscv-zce-llvm14.

I think we have solved the problem, so I am going to close this issue. if there is still a problem, please reopen it
