I do see regressions for zve32x-3.c et al. Those might be related to the recently fixed tests regarding partial vectorization with vector(1) typesbut I haven't checked further for now.
The regressions are "scan failures". One loop is not loop vectorized any more but SLP vectorized and the final output is similar. Given the changes in the patch this looks expected and we just need to adjust the scans.
