I know how to write functions in assembly so that they C-callable; if the C-callable name is foo() then the assembly function is named _foo().
What if I want to use C++ and optimize a class method in assembly? How do I do that? I assume the only major issues are:
- naming
- accessing the "this" pointer
- accessing class members by somehow knowing offsets
and if I don't want to worry about the last two, then perhaps I would write a static member function and do this:
class MyClass
{
int x;
static int _doSomething(int u); // implement this in assembly
public:
inline void doSomething() { x = _doSomething(x); } // lightweight C++ wrapper to handle the class member / "this" pointer stuff
};
