The gcc.attribute module just reuses the UDA mechanism, the value after @ can
be any kind of compile-time evaluated tuple or literal.

So you can do instead. if it makes things much nicer for you.

static if (GNU_ARM_EABI_Unwinder)
    enum personality_fn_attributes = attribute("target", ("general-regs-only"))
else
    enum personality_fn_attributes = "";

@personality_fn_attributes
private _Unwind_Reason_Code __gdc_personality(...)
