问题描述
我想知道MIPS syscall和trap指令之间是否有任何区别.我找不到与此相关的任何内容，因此不确定是否有区别.陷阱似乎只是有条件的系统调用，但进行一些澄清可能会有所帮助.
I am wondering if there is any difference between the MIPS syscall and trap instructions. I can't find anything involving this, so I am not sure if there is a difference. Traps seem to just be a conditional syscall, but some clarifying can be helpful.
推荐答案
SYSCALL和TRAP指令均触发异常，但是产生的异常类型不同(SystemCall与Trap)，并且操作系统将可能会以不同的方式处理它们.
The SYSCALL and TRAP instructions both trigger exceptions, but the resulting exception is of a different type (SystemCall versus Trap), and the operating system will likely handle them differently.
