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.

>>35-37
Yes and no. The instruction pointer register was named: ip, eip, rip, for 16bit x86, 32bit x86 and 64bit x86. in the case of ip and eip, all the bits are in use, however as >>37 said, only 48bits are currently used for addressing. So, in the case of EIP, you can't use it for extra storage, but in the case of RIP, you can (at least for now). I once disassembled some x86_64 kernel code (from ntoskrnl) and saw that they do indeed use the upper bits for special purposes. I could also see some languages like Lisps benefit from this as they could use it to tag data.
