--- Comment #3 from Matthias Kretz (Vir) <mkretz at gcc dot gnu.org> --- As a simple "solution" I could change the target selector of 'dg-do run' to 'target avx512f', which makes the test match the original PR. And then make this PR about find_last_set not working on all other non-AVX512 systems but mine. ;)
