Segher Boessenkool <segher at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Last reconfirmed| |2020-03-11 Ever confirmed|0 |1 --- Comment #5 from Segher Boessenkool <segher at gcc dot gnu.org> --- Confirmed. On p9 it is all fine. On p7 it is worse, you get std's followed by an lxvd2x from the same stack address (big LHS/SHL hazard there), and then two stxvd2x. On p8 the TImode values aren't split at all, not until final output anyway.
