Hi, I am currently developing a new pass in the late_ipa_passes phase, located behind the pass_ipa_pta and in front of the pass_omp_simd_clone. I now hope that after the pass I developed, the code can be vectorized, that is, the code that can be vectorized during the pass_omp_simd_clone.
But not yet, I'm guessing that maybe it's because I added some dead code during the pass I developed, so I want to be followed by a DCE pass right after my pass, hoping that this will allow pass_omp_simd_clone to vectorize the code after my pass. But I've found that adding NEXT_PASS(pass_dce) directly after my pass results in a runtime error, so I would like to ask if there is any good way to get pass_dce to work in the late_ipa_passes phase?
