I can't do for example:

lea RAX, [RIP+something];

Generally, RIP does not seem to be available.

The general trick in x86 assembly for this is

call next;
next:
pop EAX;


The call instruction pushes RIP to the stack (for a future ret 
instruction) but if you put it right where you are, you can 
simply pop it right back off the stack into another register.
