--- Comment #3 from Jan Hubicka <hubicka at gcc dot gnu.org> 2011-06-11 17:08:08 UTC --- The patch is expected to cause g++.dg/torture/pr43879-1_1.C. I do not get the other LTO failures. Perhaps it depends whether or not one use linker plugin. The final testing was done on gccfarm machines, so w/o plugin. What kind of error do you get there? I will look into those tomorrow. Honza
