02 x64 asm : Functions

This is the second lesson in intermediate assembly language programming in linux for x64 architecture.
NOTE: I forgot to change a few of the comments on the write_console function. That is corrected in the source code.

I want you to make more of these videos. Please don't let me down.

[@cmdcs1]

Good to see this series back 🙂

[@thebirdhasbeencharged]

I concur!

[@lysdexic9129]

do you need to pass buffer to the functions can you set rsi to be buffer once and leave it?

[@artemsmirnov2963]

can you show example how to make key-value data structure or double linked list, with map filter and fold? maybe parse some file with recursion?

[@philipbohun740]

That's a good suggestion. I have another video coming showing how to read a file. After that, I may do one on creating a one of those data structures.

good! :)

how to create first class function, sort of function as param or return new function ? f(g(x,y),z) => h(t) ?

[@philipbohun740]

While you can pass function pointers around in assembly, it doesn't "natively" have the concept of first-class functions. While technically you could implement it in assembly, using it in assembly (instead of a higher level language) would be very painful.

@@philipbohun740 yes, instead polymorphism we have only label. But how to make sort of derivative calculation d-dx (lambda squere x) -> (lambda 2 * x) ?

@@philipbohun740 is it so painful g'(f(x)) = lanbda{(f(x) + epsilon) - f(x)/epsilon} ? or is it so painful lazy stream ?
