Substitutes for x86 assembly 'call' instruction?

Question

What are some alternatives to the x86 call instruction? Maybe something like a push of the return address then a jump?

Also is their a command for obtaining the curr

Answer 1

If I don't get something mixed up I would say it depends. As you can see here there are near and far calls, but let's just consider the near call. There are again two possibilities

E8  # relative
FF 
 # absolute

whereas FF means an absolute "jump" and E8 indeed means relative to current eip.

So if you have e.g.

E8 32 45 ab 6f

which means

call 0x3245ab6f

This would translate to

push %eip
add $0x3245ab6f, %eip

and not

push %eip
jmp $0x3245ab6f
