I found that difference(ILP32 disabled/ILP32 unmerged) is bigger when aarch32 el0 is enabled, compare with aarch32 el0 disabled kernel. And bzip2, mcg, hmmer, libquantum are the top four differences[1]. Note that bigger is better in specint test. In order to make sure the above results, I retest these four testcases in reportable way(reference the command in the end). The result[2] show that libquantum decrease -2.09% after ILP32 enabled and aarch32 on. I think it is in significant. The result of lmbench is not stable in my board. I plan to dig it later.
