Ddebugging.rst38 3. 有趣的Q位
41 某些非常关键的代码必须清除PSW中的Q位。当Q位被清除时，CPU不会更新中断处理
42 程序所读取的寄存器，以找出机器被中断的位置——所以如果你在清除Q位的指令和再
43 次设置Q位的RFI之间遇到中断，你不知道它到底发生在哪里。如果你幸运的话，IAOQ
44 会指向清除Q位的指令，如果你不幸运的话，它会指向任何地方。通常Q位的问题会

22 Q: Is BPF a generic virtual machine ?
29 Q: Why C calling convention was chosen?
39 Q: Can multiple return values be supported in the future?
43 Q: Can more than 5 function arguments be supported in the future?
49 Q: Can BPF programs access instruction pointer or return address?
53 Q: Can BPF programs access stack pointer ?
62 Q: Does C-calling convention diminishes possible use cases?
74 Q: Does it mean that 'innovative' extensions to BPF code are disallowed?
