Lu <[email protected]> Date: Fri Jun 26 08:43:20 2026 +0800 determine_block_size: Set len_rtx to min size if min size == max size added + gcc_assert (min_size != max_size + || rtx_equal_p (ops[2].value, ops[6].value)); But the number of operands isn't fixed and may be less than 7. Replace the min size rtx with GEN_INT (min_size) to support different numbers of operands. ---------------cut end ---------------------- Others LGTM. -- BR, Hongtao
