I suspect one thing here: if "%%a requires memory" is accurate vs. "%%a requires a memory reference". Reference the words from doc: https://gcc.gnu.org/onlinedocs/gcc/Extended-Asm.html#Generic-Operand-Modifiers a: Substitute a memory reference, with the actual operand treated as the address. And for below code: '("#%a0" : :"m"(x))' is not accepted. While '("#%a0" : :"r"(&x))' is ok. So, it may be more accurate that: "%%a" as requirement of address of memory. Any comments? Thanks!
