    I am currently seeking guidance regarding the submission of code for SIMD (Single Instruction, Multiple Data) optimization targeting the LoongArch architecture, akin to the SSE series. The locally optimized version is currently compatible with the 5.15 version. Could you please advise whether it would be appropriate for me to submit the relevant code on the 5.15 branch? Alternatively, would it be preferable to submit it on the dev branch?

      Qt5. 15 will not get anything except urgent bug fixes.

        Because there is a significant difference between the code in the 5.15 version and the dev branch, submitting on the dev branch would be a major undertaking. I'm sorry to confirm again, but am I correct in understanding that I can only submit on the dev branch? Also, besides ensuring that the submitted code passes the tests under the /tests/auto directory, what other issues should I pay attention to?

        Thank you.

          Yes, patches have to go into the dev branch and then into the other branches if possible/needed/allowed.
