Subject: Question about JUMP and LINK
Date: Fri, 16 Mar 2012 14:52:03 +0800	[thread overview]
Message-ID: <4F62E313.3070707@gmail.com> (raw)

Hi, All

The question is simple.

func_a {

    call func_b
}

func_b {

    call func_c
}

func_c {

	return to func_a
}


The compiler I use let func_c to return func_a directly, IOW when func_b
calls func_c, it use JUMP, other JUMP and LINK, and it's definitely not
a question about inline or noinline.

So can I ask why how to let the compiler use JUMP and LINK when func_b
calls func_c?

If it's not the right place to post this, sorry for the noise.

thanks
