How bad do branch misses hurt a programs performance? In C and Java?
for example how big of an impact would :
be knowing that val will most likely be 0 99% of the time compared to the below function
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;
}
