Branch Misses

How bad do branch misses hurt a programs performance? In C and Java?

for example how big of an impact would :


int shitinanus()
{
    int val = getanus();
    if(val != 0)
        return ANALTONIGHT;
    return ALONETONIGHT;
}

be knowing that val will most likely be 0 99% of the time compared to the below function


int shitinanus()
{
    int val = getanus();
    if(val == 0)
        return ALONETONIGHT;
    return ANALTONIGHT;
}

Listen little girl, there is a reason why those of us program who living preach the standards. This is because some of us have to compile the same fucking thing on 8 different platforms. If you have non standard/non conforming code, then the works becomes a lot more difficult.

But you wouldn't know anything about this. Now go scrub another toilet and keep studying SICP you fucking nowhere bitch.
