+ * i386-dis.c (MOVSXD_Fixup): New function.
+ (movsxd_mode): New enum.
+ (x86_64_table): Use MOVSXD_Fixup and movsxd_mode on movsxd.
+ (intel_operand_size): Handle movsxd_mode.
+ (OP_E_register): Likewise.
+ (OP_G): Likewise.
+ * i386-opc.tbl: Remove Rex64 and allow 32-bit destination
+ register on movsxd. Add movsxd with 16-bit destination register
+ for AMD64 and Intel64 ISAs.
+ * i386-tbl.h: Regenerated.
