--- Comment #13 from Richard Earnshaw <rearnsha at gcc dot gnu.org> --- On armv8-a thumb2 is currently restricting IT instructions to a single 16-bit conditional insn; but movdfcc always needs at least one 32-bit conditional insn, so is disabled. A work-around is to add -mno-restrict-it; but we should probably just disable that flag since no core I know of really benefits from the restrictions it imposes on the compiler.
