Sorry, I finished it but didn't push up. I changed the flow of the conformance test, which was better. No need for the operation of copying any more.

```shell $ make RISCV_PREFIX=riscv-none-embed- RISCV_DEVICE=rv32i TARGET_SIM=/abs/to/emu-rv32i RISCV_TARGET=rv32emu TARGETDIR=/abs/to/riscv-target variant ... make[1]: Leaving directory '/path/to/riscv-compliance/riscv-test-suite/rv32i' riscv-test-env/verify.sh Compare to reference files ... Check comb ... OK Check I-ADD-01 ... OK Check I-ADDI-01...

Sorry, It's been a while for not updating this PR. Except I will delete the CSR.h file which is not necessary for this conformance test. My integrity of conformance tests...

Sorry, I have a question. Do I need to rework all the commit messages?

Hello, Jserv I have reworked these commit messages. Please check, thank you~

Not yet, I will update it tomorrow. Jim Huang 於 2020年1月17日 週五 上午1:10寫道： > Reworked yet? > > — > You are receiving this because you authored the thread. >...
