@philnik @Mordante Hi reviewers! Thank you very much for your attention to this patch! There are exactly still many issues with this patch. In addition to the problems you mentioned, there are also problems with the logic of some tests. And there are still 4 tests that failed on arm64. And We have not run the test in Aarch64 and PPC environments. I believe that fixing these issues is necessary before the patch is merged.

FYI, the implementation of Zvamo, Zvlsseg, Zvediv and Pseudo instructions is available here: https://github.com/isrc-cas/rvv-llvm
