ASSEMBLY

I've decided I'd like to try and learn assembly in my spare time.

But I want to know how hard it would be compared to learning C.

And also if you know assembly, how long did it take you to learn and how often do you end up using it?

Not really sure how threads like these go down on /prog/ but I figured here is the best place to ask at least.

EIP points to the current instruction, so you can't really use it to meaninfully store anything without crashing the thread.
On Intel 64 I imagine you could use the upper bits to store things.

I dont think so.
I dont know much about IA64 and the way of addressing for that matter, but i dont think there are 32 extra bits in RIP just unused.

>>36
Not 32, but at least 16 since 64-bit addresses are only 48 bits wide.
