--- Comment #3 from ktkachov at gcc dot gnu.org ---
I remember noticing weird loads to VFP regs when investigating PR59913 and
looking at the assembly output of genattrtab. That was at least as far back as
r206958.
pinskia: Playing with the TARGET_REGISTER_MOVE_COST hook in arm did not make a
difference, even when I set the move between GPR and VFP regs to ridiculously
high numbers
