Hi,
I am trying to use recog_data.operand in ASM_OUTPUT_OPCODE to access the
operands of the current insn for printing as the documentation for
ASM_OUTPUT_OPCODE suggests. However, this does not work for printing
inline assembly because asm insns are never matched. How can I
distinguish recognized from unrecognized insns in ASM_OUTPUT_OPCODE?
Thank you,
Charles

Try using the variable this_is_asm_operands.
ASM_OUTPUT_OPCODE is an old macro that doesn't get used much anymore.
FINAL_PRESCAN_INSN is better if you can use it. No recog_data.operand
trickery is needed here, as this one has the operands passed into it as
a macro argument. Or maybe you can use the two macros in combination to
get the behaviour you need.
