If two SFTs score equal we need to discriminate them somehow. DECL_UID is exactly the right thing to use for this. Note that 2007-10-25 Richard Guenther ... * tree-ssa-alias.c (mem_sym_stats): ... here and make it static. ... (compare_mp_info_entries): Make sort stable by disambiguating on DECL_UID. might have improved the situation. Or worsened it. The question would be - why should the DECL_UIDs for SFTs change spontaneously? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30194
