Peter Bergner <bergner at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |ASSIGNED Assignee|unassigned at gcc dot gnu.org |bergner at gcc dot gnu.org --- Comment #3 from Peter Bergner <bergner at gcc dot gnu.org> --- This looks to be a similar problem that I fixed in PR83399 except that the store here isn't generated by a builtin, but by Kelvin's optimization here: https://gcc.gnu.org/ml/gcc-patches/2018-01/msg01115.html My guess is we'll need a similar fix here, meaning tighten some predicates used in some vsx patterns/splitters. I'll have a look.
