Use goto

I'm using goto outside assembly and there's nothing you can do about it, meanwhile your jewish teachers gave your looping toys and forbid faster code for you.

Very common idiom in kernel code:

int foo(int x)
{
    int status = 0;
       
    (void) bar(x);

    if (0 != baz(x)) {
        status = -1;
        goto out1;
    }
   
    (void) qux(x);
out1:
    unbar(x);
    return status;
}

This saves writing a stub function just to break out and unbar if baz fails.

I've used goto before, but it isn't that necessary here.


int foo(int x)
{
    int status = 0;
      
    (void) bar(x);

    if (baz(x) == 0)
    {
      (void) qux(x);
    }
    else
    {
      status = -1;
    }
    unbar(x);
    return status;
}
