--- Comment #4 from Oleg Endo <olegendo at gcc dot gnu.org> --- Loads from volatile mems have been fixed on 4.9 trunk. While working on it I noticed that stores to volatile mems have basically the same issue. I'll try to come up with a fix for that, too. http://gcc.gnu.org/viewcvs/gcc?view=revision&revision=200350 PR target/52483 * config/sh/predicates.md (general_extend_operand): Invoke general_movsrc_operand for memory operands.
