--- Comment #17 from qinzhao at gcc dot gnu.org --- So, based on the discussion so far, I'd like to take the following steps: 1. In GCC12, I will take a conservative solution to fix this bug, i.e: mark the load "MEM" as not needing a warning during __builtin_clear_padding folding phase; this should resolve this issue and has lowest risk to introduce more issues. 2. In GCC13, seeking a better way to do padding initialization. right now, based on the discussion so far, there is no conclusion on which way is better yet. let me know if you have other comments or suggestions.
