Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- See Also| |https://gcc.gnu.org/bugzill | |a/show_bug.cgi?id=107099 --- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Note -fdisable-tree-uncprop1 makes it even slightly better. I suspect un-copy-prop (which tries to undo copy prop into phi nodes) is doing something it should not.
