+ * arm.c (arm_const_double_inline_cost): Handle any constant by
+ using gen_lowpart and gen_highpart_mode.
+ (note_invalid_constants): All constants in an RTX with a constraint
+ that permits memory are now pushed to the constant pool.
+ (output_move_double): Delete code to handle reg to reg and
+ constant to reg moves.
+ (const_double_needs_minipool, output_mov_immediate): Delete.
+ * arm.h (EXTRA_CONSTRAINT_STR_ARM): All 'D' variants now handle
+ CONST_INT and CONST_VECTOR.
+ * arm.md (ANY64): New mode macro.
+ (arm_movdi): Split reg-reg and const-reg moves. Simplify constraints.
+ (movdf_soft_insn): Split reg-reg and const-reg moves.
+ (split patterns for 64-bit constant and register moves): New.
+ * cirrus.md (cirrus_arm_movdi): Split reg-reg and const-reg moves.
+ (cirrus_movdf_hard_insn): Likewise.
+ * fpa.md (movdf_fpa): Likewise.
+ * iwmmxt.md (iwmmxt_arm_movdi): Likewise.
+ (movv8qi_internal, movv4hi_internal, movv2si_internal): Fix
+ constraints.
+ (movv2si_internal_2): Likewise.
+ * vfp.md (arm_movdi_vfp): Split reg-reg and const-reg moves.
+ (movdf_vfp): Likewise.
