--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
In the r16-1886-gb610132ddbe4cb870b9c2752053616dcf12979fe commit I've been
expecting finally_tmp.N will be only 0/1, but on this testcase it uses 0/1/2
values and even the assumption that the SSA_NAMEs (e.g. PHI result of
finally_tmp.N has a single user is wrong, there can be multiple).
