--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
So, I've patched the r235622 cross-compiler to:
--- tree-ssa-alias.c.xx 2017-02-21 19:17:36.000000000 +0100
+++ tree-ssa-alias.c 2017-02-22 11:37:12.714172891 +0100

and for the SSA_NAMEs printed with PTRS_COMPARE_UNEQUAL=10000 tested assembly
for PTRS_COMPARE_UNEQUAL set to all those versions.
This gave me (10000 is randomly chosen SSA_NAME that doesn't appear in the
list, so effectively all ptrs_compare_unequal return false):
