What is the difference between MOV and LEA?
...
In NASM syntax:
mov eax, var == lea eax, [var] ; i.e. mov r32, imm32
lea eax, [var+16] == mov eax, var+16
lea eax, [eax*4] == shl eax, 2 ; but without setting flags
In MASM syntax, use OFFSET var to get a mov-immediate instead of a load.

How does C compute sin() and other math functions?

What is the size of an enum in C?
I'm creating a set of enum values, but I need each enum value to be 64 bits wide. If I recall correctly, an enum is generally the same size as an int; but I thought I read somewhere that (at least in GCC) the compiler can make the enum any width they need to be to hold their values. So, is it possib...
