> Hi @HsiangKai, I want to know how you have written 12877+ lines of test cases such as in https://github.com/llvm/llvm-project/blob/main/llvm/test/CodeGen/RISCV/rvv/vluxseg-rv32.ll . I need to update them in this patch to pass check-llvm. It is some script? can you please tell me how to use that.

Read the very first line:

  ; NOTE: Assertions have been autogenerated by utils/update_llc_test_checks.py

Almost every test in llvm/test/CodeGen/RISCV uses that, you should rarely have to update them manually (I hope you didn't do so for all these tests here... if you did, please re-run the script on all of them, because the script can include things a human might not, e.g. you can see comments on many of the lines that technically aren't needed, but using the script ensures that when someone re-runs it they don't see spurious diffs).
