Register Variables

some say floats can't be stored in register.
size of int and float are same ( on some machine am i Wrong?)
so if int can be delcared as register than why not float(where in and
float are of same size) ?

My experience has been that with high levels of optimization, is that

So I've stopped using it for general coding, only trying it when I'm
trying to get better performance out of a piece of code. But even
then, the optimizer either usually out does me (or outsmarts me).

My experience is weak in the x86 arena, so some folks may have seen
different. On the SUN I'm currently using, there's so many f.p.
registers that you don't have to worry about it.


So you're using SPARC then. Scott McNealy's toy.


What sort of a troll are you?

Hi Group, I have a doubt about register variables. I know that if we have a variable used very frequently in a function, then provided we never apply the & function to it, we can define it as a register variable and this will make it much faster to access. Now the question is: obviously there are only a fixed number of registers in our CPU, maybe 6 or something. So how do we choose which

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
