Lu <hjl.to...@gmail.com> Date: Fri Nov 4 13:47:59 2022 -0700 i386: Check invalid (%dx) usage (%dx) isn't a valid memory address in any modes. It is used as a special memory operand for input/output port address in AT&T syntax and should only be used with input/output instructions. Update i386_att_operand to set i.input_output_operand to true for (%dx) and issue an error if (%dx) is used with non-input/output instructions. PR gas/29751 * config/tc-i386.c (_i386_insn): Add input_output_operand. (md_assemble): Issue an error if input/output memory operand is used with non-input/output instructions.
