ktkachov at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- Known to fail| |4.9.4, 5.2.1, 6.0 --- Comment #3 from ktkachov at gcc dot gnu.org --- Ok, I think I see the problem here. *arm32_movhf should not just have a !arm_restrict_it in its predicate, it should disable the alternatives in a smarter way. I'll see what I can do.
