How to eliminate "if continue " or "if break" statements in loop ?

hi,ti optimization experts!

Now I always find many "if continue " and " if break " statements in my algorithms.These statements prevented to produce software pipeline in loops and has poor 

performance.for example:

how to optimize code like this:

for(...)

{

if (A) continue;

if(B)  break;

}

when I compilered these code,I would found feedback information like this  "Disqualified loop: Loop contains control code "; So, I couldn't know how to eliminate 

"if break" and "if continue" to produce software pipeline.
