How to check the EIP value with assembly language? [duplicate]

Answer 1

Assuming 32-bit x86, use the following function:

get_eip: mov eax, [esp]
         ret

Then, to get the value of EIP in EAX, simply:

call get_eip

Answer 2

On x86-64 (as opposed to 32 bit x86), there's RIP-relative addressing (RIP is the 64-bit analogue of EIP). So in 64-bit code, you can just do

lea rax, [rip]

to move the current contents of RIP to RAX (you can use lea but not mov for this).

Answer 3

    call foo
foo:
    pop eax ; address of foo
