I've try to change march combination but which doesn't seems like the root cause of this issue. Even `-march=rv32gc_zve32f_xsfmm128t` could fail. But during the debug process I found that the root cause of this issue is from the `-O3` flag. The pass error could also happen for `-O2` flag. If I turn optimization flag off, or with `-O1`, `-O0`(the default optimization), `-Og`, the above problematic code could be compile successfully. https://github.com/llvm/llvm-project/pull/133031 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
