How can I detect at compile time from an ASM source file if the target architecture is I386 or AMD64?
So I took a look at the x86 assembly language; All the commands are pretty clear but: I don\'t see anything that can actually trigger something in the computer like: Access RAM and not only CPU regist
As far as I understood it, BigInts are usually implemented in most programming languages as arrays containing digits, where, eg.: when adding two of them, each d开发者_如何学Cigit is added one after a

What is the cost of the atomic operation (any of compare-and-swap or atomic add/decrement)? How much cycles does it consume? Will it pause other processors on SMP or NUMA, or will it block memory acce

I have a basic question about assembly. Why do we bother doing arithmetic operations only on registers if they can work on memory as well?
